In 2003, 695,500 live births were registered in the United Kingdom; 38 per cent occurred outside marriage. Overall, total fertility is falling slowly. The number of births per 1,000 women aged over 40 years has been rising, and in 1999 was 8.9 per cent. In Great Britain in 2003, 193,817 legal abortions were performed under the Abortion Act 1967.... birth rate
The proportion of deaths in a specified population. The death rate is calculated by dividing the number of deaths in a population in a year by the midyear resident population. Death rates are often expressed as the number of deaths per 100 000 persons. The rate may be restricted to deaths in specific age, race, sex, or geographic groups or deaths from specific causes of death (specific rate), or it may be related to the entire population (crude rate).... death rate

A common form of irritant contact DERMATITIS in the nappy area in babies under one year old. Wetting of the skin by urine, abrasion, and chemical changes due to faecal contamination all play a part. Good hygiene and use of disposable absorbent nappies have much reduced its incidence. An ointment containing a barrier, such as titanium dioxide, may help; other medications such as mild CORTICOSTEROIDS or antibiotics should be used very cautiously and only under the guidance of a doctor, as harmful effects may result – especially from overuse.... nappy rash

This NERVE arises from the BRACHIAL plexus in the axilla. At ?rst descending posteriorly and then anteriorly, it ends just above the elbow by dividing into the super?cial radial and interosseous nerves. It supplies motor function to the muscles which extend the arm, wrist, and some ?ngers, and supplies sensation to parts of the posterior and lateral aspects of the arm, forearm and hand.... radial nerve
The term applied to the nausea, vomiting and loss of appetite which may follow exposure to RADIATION – for example, at work – or the use of RADIOTHERAPY in the treatment of cancer and other diseases. People exposed to radiation at work should have that exposure carefully monitored so it does not exceed safety limits. Doses of radiation given during radiotherapy treatment are carefully measured: even so, patients may suffer side-effects. The phenothiazine group of tranquillisers, such as CHLORPROMAZINE, as well as the ANTIHISTAMINE DRUGS, are of value in the prevention and treatment of radiation sickness.... radiation sickness
Breakdown of the nuclei of some elements resulting in the emission of energy in the form of alpha, beta and gamma rays. Because of this particle emission, the elements decay into other elements.

A technique introduced in 1960 which enables the minute quantities of natural substances in the blood such as HORMONES to be measured. A radioimmunoassay depends upon the ability of an unlabelled hormone to inhibit, by simple competition, the binding of isotopically labelled hormone by speci?c ANTIBODIES. The requirements for a radioimmunoassay include adequate amounts of the hormone; a method for labelling the hormone with a radioactive isotope; the production of satisfactory antibodies; and a technique for separating antibody-bound from free hormone. Radioimmunoassay is more sensitive than the best bioassay for a given hormone, and the most sensitive radioimmunoassays permit the detection of picogram (pg = 10?12g) and femtogram (fg = 10?15g) amounts of material.... radioimmunoassay
The radiations of radium consist of: (1) alpha rays, which are positively charged helium nuclei; (2) beta rays – negatively charged electrons; (3) gamma rays, similar to X-RAYS but of shorter wavelength. These days the use of radium is largely restricted to the treatment of carcinoma of the neck of the womb, the tongue, and the lips. Neither X-rays nor radium supersede active surgical measures when these are available for the complete removal of a tumour.... radium

An H2-receptor antagonist drug used in the treatment of DUODENAL ULCER by reducing the hyperacidity of the gastric juice. The drug blocks the production of histamine produced by mast cells in the stomach lining. Histamine stimulates the acid-secreting cells in the stomach. Ranitidine, like other H2-blocking drugs, should be used in combination with an antibiotic drug to treat ulcers caused by Helicobacter pylori infection in the stomach. The drug should be given for up to eight weeks with repeat courses if ulcers recur.... ranitidine

If an individual is unconscious – whether as a result of accident or illness or when in the postoperative recovery unit – but is breathing and has a pulse, he or she should be placed in the recovery position. The individual is turned on his or her side to allow the tongue to fall forwards and so reduce the likelihood of pharyngeal obstruction (see PHARYNX). Fluid in the mouth can also drain outwards instead of into the TRACHEA and LUNGS. The person can lie on either side with upper or lower leg ?exed. Sometimes the semi-prone position is used; this gives better drainage from the mouth and greater stability during transport, but makes it more di?cult to observe the face, colour or breathing. (See APPENDIX 1: BASIC FIRST AID.)... recovery position
The last part of the large INTESTINE. It pursues a more or less straight course downwards through the cavity of the pelvis, lying against the sacrum at the back of this cavity. This section of the intestine is about 23 cm (9 inches) long: its ?rst part is freely movable and corresponds to the upper three pieces of the sacrum; the second part corresponds to the lower two pieces of the sacrum and the coccyx; whilst the third part, known also as the anal canal, is about 25 mm (1 inch) long, runs downwards and backwards, and is kept tightly closed by the internal and external SPHINCTER muscles which surround it. The opening to the exterior is known as the ANUS. The structure of the rectum is similar to that of the rest of the intestine.... rectum
The deviation of rays of light on passing from one transparent medium into another of di?erent density. The refractive surfaces of the EYE are the anterior surface of the cornea (which accounts for approximately two-thirds of the focusing or refractive power of the eye), and the lens (one-third of the focusing power of the eye). The refractive power of the lens can change, whereas that of the cornea is ?xed. (For errors of refraction, see under EYE, DISORDERS OF.)... refraction

So-called because of the characteristic temperature chart showing recurring bouts of fever, this is an infectious disease caused by SPIROCHAETE. There are two main forms of the disease.
Louse-borne relapsing fever is an EPIDEMIC disease, usually associated with wars and famines, which has occurred in practically every country in the world. For long confused with TYPHUS FEVER and typhoid fever (see ENTERIC FEVER), it was not until the 1870s that the causal organism was described by Obermeier. It is now known as the Borrelia recurrentis, a motile spiral organism 10–20 micrometres in length. The organism is transmitted from person to person by the louse, Pediculus humanus.
Symptoms The incubation period is up to 12 days (but usually seven). The onset is sudden, with high temperature, generalised aches and pains, and nose-bleeding. In about half of cases, a rash appears at an early stage, beginning in the neck and spreading down over the trunk and arms. JAUNDICE may occur; and both the LIVER and the SPLEEN are enlarged. The temperature subsides after ?ve or six days, to rise again in about a week. There may be up to four such relapses (see the introductory paragraph above).
Treatment Preventive measures are the same as those for typhus. Rest in bed is essential, as are good nursing and a light, nourishing diet. There is usually a quick response to PENICILLIN; the TETRACYCLINES and CHLORAMPHENICOL are also e?ective. Following such treatment the incidence of relapse is about 15 per cent. The mortality rate is low, except in a starved population.
Tick-borne relapsing fever is an ENDEMIC disease which occurs in most tropical and sub-tropical countries. The causative organism is Borrelia duttoni, which is transmitted by a tick, Ornithodorus moubata. David Livingstone suggested that it was a tick-borne disease, but it was not until 1905 that Dutton and Todd produced the de?nitive evidence.
Symptoms The main di?erences from the louse-borne disease are: (a) the incubation period is usually shorter, 3–6 days (but may be as short as two days or as long as 12); (b) the febrile period is usually shorter, and the afebrile periods are more variable in duration, sometimes only lasting for a day or two; (c) relapses are much more numerous.
Treatment Preventive measures are more di?cult to carry out than in the case of the louse-borne infection. Protective clothing should always be worn in ‘tick country’, and old, heavily infected houses should be destroyed. Curative treatment is the same as for the louse-borne infection.... relapsing fever

An ENZYME produced by the kidney (see KIDNEYS) and released into the blood in response to STRESS. Renin reacts with a compound produced by the liver to produce ANGIOTENSIN. This causes blood vessels to constrict and raises the blood pressure. If too much renin is produced, this results in renal HYPERTENSION.... renin

The process in which air passes into and out of the lungs so that the blood can absorb oxygen and give o? carbon dioxide and water. This occurs 18 times a minute in a healthy adult at rest and is called the respiratory rate. An individual breathes more than 25,000 times a day and during this time inhales around 16 kg of air.
Mechanism of respiration For the structure of the respiratory apparatus, see AIR PASSAGES; CHEST; LUNGS. The air passes rhythmically into and out of the air passages, and mixes with the air already in the lungs, these two movements being known as inspiration and expiration. INSPIRATION is due to a muscular e?ort which enlarges the chest, so that the lungs have to expand in order to ?ll up the vacuum that would otherwise be left, the air entering these organs by the air passages. The increase of the chest in size from above downwards is mainly due to the diaphragm, the muscular ?bres of which contract and reduce its domed shape and cause it to descend, pushing down the abdominal organs beneath it. EXPIRATION is an elastic recoil, the diaphragm rising and the ribs sinking into the position that they naturally occupy, when muscular contraction is ?nished. Occasionally, forced expiration may occur, involving powerful muscles of the abdomen and thorax; this is typically seen in forcible coughing.
Nervous control Respiration is usually either an automatic or a REFLEX ACTION, each expiration sending up sensory impulses to the CENTRAL NERVOUS SYSTEM, from which impulses are sent down various other nerves to the muscles that produce inspiration. Several centres govern the rate and force of the breathing, although all are presided over by a chief respiratory centre in the medulla oblongata (see under BRAIN – Divisions). This in turn is controlled by the higher centres in the cerebral hemispheres, so that breathing can be voluntarily stopped or quickened.
Quantity of air The lungs do not completely empty themselves at each expiration and re?ll at each inspiration. With each breath, less than one-tenth of the total air in the lungs passes out and is replaced by the same quantity of fresh air, which mixes with the stale air in the lungs. This renewal, which in quiet breathing amounts to about 500 millilitres, is known as the tidal air. By a special inspiratory e?ort, an individual can draw in about 3,000 millilitres, this amount being known as complemental air. By a special expiratory e?ort, too, after an ordinary breath one can expel much more than the tidal air from the lungs – this extra amount being known as the supplemental or reserve air, and amounting to about 1,300 millilitres. If an individual takes as deep an inspiration as possible and then makes a forced expiration, the amount expired is known as the vital capacity, and amounts to around 4,000 millilitres in a healthy adult male of average size. Figures for women are about 25 per cent lower. The vital capacity varies with size, sex, age and ethnic origin.
Over and above the vital capacity, the lungs contain air which cannot be expelled; this is known as residual air, and amounts to another 1,500 millilitres.
Tests of respiratory e?ciency are used to assess lung function in health and disease. Pulmonary-function tests, as they are known, include spirometry (see SPIROMETER), PEAK FLOW METER (which measures the rate at which a person can expel air from the lungs, thus testing vital capacity and the extent of BRONCHOSPASM), and measurements of the concentration of oxygen and carbon dioxide in the blood. (See also LUNG VOLUMES.)
Abnormal forms of respiration Apart from mere changes in rate and force, respiration is modi?ed in several ways, either involuntarily or voluntarily. SNORING, or stertorous breathing, is due to a ?accid state of the soft palate causing it to vibrate as the air passes into the throat, or simply to sleeping with the mouth open, which has a similar e?ect. COUGH is a series of violent expirations, at each of which the larynx is suddenly opened after the pressure of air in the lungs has risen considerably; its object is to expel some irritating substance from the air passages. SNEEZING is a single sudden expiration, which di?ers from coughing in that the sudden rush of air is directed by the soft palate up into the nose in order to expel some source of irritation from this narrow passage. CHEYNE-STOKES BREATHING is a type of breathing found in persons suffering from stroke, heart disease, and some other conditions, in which death is impending; it consists in an alternate dying away and gradual strengthening of the inspirations. Other disorders of breathing are found in CROUP and in ASTHMA.... respiration
Inflammation of the retina... retinitis
A rare malignant growth of the retina (see EYE) which occurs in infants. It can sometimes be discovered at birth because shining a light in the baby’s pupil produces a white re?ection rather than a red one. Alternatively, the infant may present with a SQUINT or a mass in the abdomen. In 25 per cent of cases there is a family history of the condition and abnormality of chromosome 13 is common (see CHROMOSOMES). It is treated by removing the eye or, if affecting both eyes, by laser PHOTOCOAGULATION with or without RADIOTHERAPY.... retinoblastoma

An acute febrile illness, usually seen in children, which may include ARTHRALGIA, ARTHRITIS, CHOREA, carditis (see below) and rash (see ERUPTION). The illness has been shown to follow a beta-haemolytic streptococcal infection (see STREPTOCOCCUS).
Rheumatic fever is now extremely uncommon in developed countries, but remains common in developing areas. Diagnosis is based on the presence of two or more major manifestations – endocarditis (see under HEART, DISEASES OF), POLYARTHRITIS, chorea, ERYTHEMA marginatum, subcutaneous nodules – or one major and two or more minor ones – fever, arthralgia, previous attacks, raised ESR, raised white blood cell count, and ELECTROCARDIOGRAM (ECG) changes. Evidence of previous infection with streptococcus is also a criterion.
Clinical features Fever is high, with attacks of shivering or rigor. Joint pain and swelling (arthralgia) may affect the knee, ankle, wrist or shoulder and may migrate from one joint to another. TACHYCARDIA may indicate cardiac involvement. Subcutaneous nodules may occur, particularly over the back of the wrist or over the elbow or knee. Erythema marginatum is a red rash, looking like the outline of a map, characteristic of the condition.
Cardiac involvement includes PERICARDITIS, ENDOCARDITIS, and MYOCARDITIS. The main long-term complication is damage to the mitral and aortic valves (see HEART).
The chief neurological problem is chorea (St Vitus’s dance) which may develop after the acute symptoms have subsided.
Chronic rheumatic heart disease occurs subsequently in at least half of those who have had rheumatic fever with carditis. The heart valve usually involved is the mitral; less commonly the aortic, tricuspid and pulmonary. The lesions may take 10–20 years to develop in developed countries but sooner elsewhere. The heart valves progressively ?brose and ?brosis may also develop in the myocardium and pericardium. The outcome is either mitral stenosis or mitral regurgitation and the subsequent malfunction of this or other heart valves affected is chronic failure in the functioning of the heart. (see HEART, DISEASES OF).
Treatment Eradication of streptococcal infection is essential. Other features are treated symptomatically. PARACETAMOL may be preferred to ASPIRIN as an antipyretic in young children. One of the NON-STEROIDAL ANTIINFLAMMATORY DRUGS (NSAIDS) may bene?t the joint symptoms. CORTICOSTEROIDS may be indicated for more serious complications.
Patients who have developed cardiac-valve abnormalities require antibiotic prophylaxis during dental treatment and other procedures where bacteria may enter the bloodstream. Secondary cardiac problems may occur several decades later and require replacement of affected heart valves.... rheumatic fever
The condition characterised by swelling of the NOSE due to enormous enlargement of the sebaceous glands which may develop in the later stages of ROSACEA.... rhinophyma
Repair of the NOSE or modi?cation of its shape by operation. This operation is performed by reconstructive and ENT (ear, nose and throat) surgeons alike. It may involve alteration of the bony skeleton of the nose and/or alteration of the SEPTUM (septorhinoplasty). It is mostly performed for cosmetic reasons; however, any disease process or injury which has caused a defect in the nose may be repaired as well. The latter problem would usually involve the utilisation of some form of skin ?ap, whereas this would not be required for cosmetic surgical purposes.... rhinoplasty
The persistent discharge of watery mucus from the NOSE. This is a usual symptom as a result of COMMON COLD or consequent upon ALLERGY (perennial rhinitis and HAY FEVER).... rhinorrhoea
A chronic in?ammation of the synovial lining (see SYNOVIAL MEMBRANE) of several joints, tendon sheaths or bursae which is not due to SEPSIS or a reaction to URIC ACID crystals. It is distinguished from other patterns of in?ammatory arthritis by the symmetrical involvement of a large number of peripheral joints; by the common blood-?nding of rheumatoid factor antibody; by the presence of bony erosions around joints; and, in a few, by the presence of subcutaneous nodules with necrobiotic (decaying) centres.
Causes There is a major immunogenetic predisposition to rheumatoid arthritis in people carrying the HLA-DR4 antigen (see HLA SYSTEM). Other minor immunogenetic factors have also been implicated. In addition, there is a degree of familial clustering which suggests other unidenti?ed genetic factors. Genetic factors cannot alone explain aetiology, and environmental and chance factors must be important, but these have yet to be identi?ed.
Epidemiology Rheumatoid arthritis more commonly occurs in women from the age of 30 onwards, the sex ratio being approximately 4:1. Typical rheumatoid arthritis may occur in adolescence, but in childhood chronic SYNOVITIS usually takes one of a number of di?erent patterns, classi?ed under juvenile chronic arthritis.
Pathology The primary lesion is an in?ammation of the synovial membrane of joints. The synovial ?uid becomes diluted with in?ammatory exudate: if this persists for months it leads to progressive destruction of articular CARTILAGE and BONE. Cartilage is replaced by in?ammatory tissue known as pannus; a similar tissue invades bone to form erosions. Synovitis also affects tendon sheaths, and may lead to adhesion ?brosis or attrition and rupture of tendons. Subcutaneous and other bursae may be involved. Necrobiotic nodules also occur at sites outside synovium, including the subcutaneous tissues, the lungs, the pericardium and the pleura.
Clinical features Rheumatoid arthritis varies from the very mild to the severely disabling. Many mild cases probably go undiagnosed. At least 50 per cent of patients continue to lead a reasonably normal life; around 25 per cent are signi?cantly disabled in terms of work and leisure activities; and a minority become markedly disabled and are limited in their independence. There is often an early acute phase, followed by substantial remission, but in other patients gradual step-wise deterioration may occur, with progressive involvement of an increasing number of joints.
The diagnosis of rheumatoid arthritis is largely based on clinical symptoms and signs. Approximately 70 per cent of patients have rheumatoid factor ANTIBODIES in the SERUM but, because of the large number of false positives and false negatives, this test has very little value in clinical practice. It may be a useful pointer to a worse prognosis in early cases if the level is high. X-RAYS may help in diagnosing early cases and are particularly helpful when considering surgery or possible complications such as pathological fracture. Patients commonly develop ANAEMIA, which may be partly due to gastrointestinal blood loss from antiin?ammatory drug treatment (see below).
Treatment involves physical, pharmacological, and surgical measures, together with psychological and social support tailored to the individual patient’s needs. Regular activity should be maintained. Resting of certain joints such as the wrist with splints may be helpful at night or to assist prolonged manual activities. Sound footwear is important. Early use of antirheumatic drugs reduces long-term disability. Drug treatment includes simple ANALGESICS, NON-STEROIDAL ANTI-INFLAMMATORY DRUGS (NSAIDS), and slow-acting drugs including GOLD SALTS (in the form of SODIUM AUROTHIOMALATE), PENICILLAMINE, SULFASALAZINE, METHOTREXATE and AZATHIOPRINE.
The non-steroidal agents are largely e?ective in reducing pain and early-morning sti?ness, and have no e?ect on the chronic in?ammatory process. It is important, especially in the elderly, to explain to patients the adverse effects of NSAIDs, the dosage of which can be cut by prescribing paracetamol at the same time. Combinations of anti-rheumatic drugs seem better than single agents. The slow-acting drugs take approximately three months to act but have a more global e?ect on chronic in?ammation, with a greater reduction in swelling and an associated fall in erythrocyte sedimentation rate (ESR) and rise in the level of HAEMOGLOBIN. Local CORTICOSTEROIDS are useful, given into individual joints. Systemic corticosteroids carry serious problems if continued long term, but may be useful under special circumstances. Much research is currently going on into the use of tumour necrosis factor antagonists such as INFLIXIMAB and etanercept, but their precise role remains uncertain.... rheumatoid arthritis

Dietary ?bre is that part of food which cannot be digested in the gastrointestinal tract, although it can be metabolised in the colon by the micro-organisms there. Roughage falls into four groups: cellulose, hemicelluloses, lignins and pectins, found in unre?ned foods such as wholemeal cereals and ?our, root vegetables, nuts and fruit. It has long been known to affect bowel function, probably because of its capacity to hold water in a gel-like form. It plays an important role in the prevention of CONSTIPATION, DIVERTICULOSIS, IRRITABLE BOWEL SYNDROME (IBS), APPENDICITIS, DIABETES MELLITUS and cancer of the colon (see INTESTINE). At present, many western diets do not contain enough roughage.... roughage
Rubella, or German measles, is an acute infectious disease of a mild type, which may sometimes be di?cult to di?erentiate from mild forms of MEASLES and SCARLET FEVER.
Cause A virus spread by close contact with infected individuals. Rubella is infectious for a week before the rash appears and at least four days afterwards. It occurs in epidemics (see EPIDEMIC) every three years or so, predominantly in the winter and spring. Children are more likely to be affected than infants. One attack gives permanent IMMUNITY. The incubation period is usually 14–21 days.
Symptoms are very mild, and the disease is not at all serious. On the day of onset there may be shivering, headache, slight CATARRH with sneezing, coughing and sore throat, with very slight fever – not above 37·8 °C (100 °F). At the same time the glands of the neck become enlarged. Within 24 hours of the onset a pink, slightly raised eruption appears, ?rst on the face or neck, then on the chest, and the second day spreads all over the body. The clinical signs and symptoms of many other viral infections are indistinguishable from rubella so a precise diagnosis cannot be made without taking samples (such as saliva) for antibody testing, but this is rarely done in practice.
An attack of German measles during the early months of pregnancy may be responsible for CONGENITAL defects in the FETUS (for information on fetal abnormalities, see under PREGNANCY AND LABOUR). The incidence of such defects is not precisely known, but probably around 20 per cent of children whose mothers have had German measles in the ?rst three months of the pregnancy are born with congenital defects. These defects take a variety of forms, but the most important ones are: low birth weight with retarded physical development; malformations of the HEART; cataract (see under EYE, DISORDERS OF); and DEAFNESS.
Treatment There is no speci?c treatment. Children who develop the disease should not return to school until they have recovered, and in any case not before four days have passed from the onset of the rash.
In view of the possible dangerous e?ect of the disease upon the fetus, particular care should be taken to isolate pregnant mothers from contact with infected subjects. As the risk is particularly high during the ?rst 16 weeks of pregnancy, any pregnant mother exposed to infection during this period should be given an intramuscular injection of GAMMA-GLOBULIN. A vaccine is available to protect an individual against rubella (see IMMUNISATION).
In the United Kingdom it is NHS policy for all children to have the combined measles, mumps and rubella vaccine (see MMR VACCINE), subject to parental consent. All women of childbearing age, who have been shown by a simple laboratory test not to have had the disease, should be vaccinated, provided that the woman is not pregnant at the time and has not been exposed to the risk of pregnancy during the previous eight weeks.... rubella
A popular name for HERNIA.... rupture
Also known as Röntgen rays, these were discovered in 1895 by Wilhelm Conrad Röntgen. Their use for diagnostic imaging (radiology) and for cancer therapy (see RADIOTHERAPY) is now an integral part of medicine. Many other forms of diagnostic imaging have been developed in recent years, sometimes also loosely called ‘radiology’. Similarly the use of chemotherapeutic agents in cancer has led to the term oncology which may be applied to the treatment of cancer by both drugs and X-rays.
The rays are part of the electro-magnetic spectrum; their wavelengths are between 10?9 and 10? 13 metres; in behaviour and energy they are identical to the gamma rays emitted by radioactive isotopes. Diagnostic X-rays are generated in an evacuated tube containing an anode and cathode. Electrons striking the anode cause emission of X-rays of varying energy; the energy is largely dependent on the potential di?erence (kilovoltage) between anode and cathode. The altered tissue penetration at di?erent kilovoltages is used in radiographing di?erent regions, for example in breast radiography (25–40 kV) or chest radiography (120–150 kV). Most diagnostic examinations use kilovoltages between 60 and 120. The energy of X-rays enables them to pass through body tissues unless they make contact with the constituent atoms. Tissue attenuation varies with atomic structure, so that air-containing organs such as the lung o?er little attenuation, while material such as bone, with abundant calcium, will absorb the majority of incident X-rays. This results in an emerging X-ray pattern which corresponds to the structures in the region examined.
Radiography The recording of the resulting images is achieved in several ways, mostly depending on the use of materials which ?uoresce in response to X-rays. CONTRAST X-RAYS Many body organs are not shown by simple X-ray studies. This led to the development of contrast materials which make particular organs or structures wholly or partly opaque to X-rays. Thus, barium-sulphate preparations are largely used for examining the gastrointestinal tract: for example, barium swallow, barium meal, barium follow-through (or enteroclysis) and barium enema. Water-soluble iodine-containing contrast agents that ionise in solution have been developed for a range of other studies.
More recently a series of improved contrast molecules, chie?y non-ionising, has been developed, with fewer side-effects. They can, for example, safely be introduced into the spinal theca for myeloradiculography – contrast X-rays of the spinal cord. Using these agents, it is possible to show many organs and structures mostly by direct introduction, for example via a catheter (see CATHETERS). In urography, however, contrast medium injected intravenously is excreted by the kidneys which are outlined, together with ureters and bladder. A number of other more specialised contrast agents exist: for example, for cholecystography – radiological assessment of the gall-bladder. The use of contrast and the attendant techniques has greatly widened the range of radiology. IMAGE INTENSIFICATION The relative insensitivity of ?uorescent materials when used for observation of moving organs – for example, the oesophagus – has been overcome by the use of image intensi?cation. A faint ?uorographic image produced by X-rays leads to electron emission from a photo-cathode. By applying a high potential di?erence, the electrons are accelerated across an evacuated tube and are focused on to a small ?uorescent screen, giving a bright image. This is viewed by a TV camera and the image shown on a monitor and sometimes recorded on videotape or cine. TOMOGRAPHY X-ray images are two-dimensional representations of three-dimensional objects. Tomography (Greek tomos
– a slice) began with X-ray imaging produced by the linked movement of the X-ray tube and the cassette pivoting about a selected plane in the body: over- and underlying structures are blurred out, giving a more detailed image of a particular plane.
In 1975 Godfrey Houns?eld introduced COMPUTED TOMOGRAPHY (CT). This involves
(i) movement of an X-ray tube around the patient, with a narrow fan beam of X-rays; (ii) the corresponding use of sensitive detectors on the opposite side of the patient; (iii) computer analysis of the detector readings at each point on the rotation, with calculation of relative tissue attenuation at each point in the cross-sectional plant. This invention has enormously increased the ability to discriminate tissue composition, even without the use of contrast.
The tomographic e?ect – imaging of a particular plane – is achieved in many of the newer forms of imaging: ULTRASOUND, magnetic resonance imaging (see MRI) and some forms of nuclear medicine, in particular positron emission tomography (PET SCANNING). An alternative term for the production of images of a given plane is cross-sectional imaging.
While the production of X-ray and other images has been largely the responsibility of radiographers, the interpretation has been principally carried out by specialist doctors called radiologists. In addition they, and interested clinicians, have developed a number of procedures, such as arteriography (see ANGIOGRAPHY), which involve manipulative access for imaging – for example, selective coronary or renal arteriography.
The use of X-rays, ultrasound or computerised tomography to control the direction and position of needles has made possible guided biopsies (see BIOPSY) – for example, of pancreatic, pulmonary or bony lesions – and therapeutic procedures such as drainage of obstructed kidneys (percutaneous nephrostomy), or of abscesses. From these has grown a whole series of therapeutic procedures such as ANGIOPLASTY, STENT insertion and renal-stone track formation. This ?eld of interventional radiology has close a?nities with MINIMALLY INVASIVE SURGERY (MIS).
Radiotherapy, or treatment by X-rays The two chief sources of the ionising radiations used in radiotherapy are the gamma rays of RADIUM and the penetrating X-rays generated by apparatus working at various voltages. For super?cial lesions, energies of around 40 kilovolts are used; but for deep-seated conditions, such as cancer of the internal organs, much higher voltages are required. X-ray machines are now in use which work at two million volts. Even higher voltages are now available through the development of the linear accelerator, which makes use of the frequency magnetron which is the basis of radar. The linear accelerator receives its name from the fact that it accelerates a beam of electrons down a straight tube, 3 metres in length, and in this process a voltage of eight million is attained. The use of these very high voltages has led to the development of a highly specialised technique which has been devised for the treatment of cancer and like diseases.
Protective measures are routinely taken to ensure that the patient’s normal tissue is not damaged during radiotherapy. The operators too have to take special precautions, including limits on the time they can work with the equipment in any one period of time.
The greatest value of radiotherapy is in the treatment of malignant disease. In many patients it can be used for the treatment of malignant growths which are not accessible to surgery, whilst in others it is used in conjunction with surgery and chemotherapy.... x-rays
Within a few years medical scientists have introduced into the domestic scene a steroid which has changed the whole course of female history. HRT has solved some basic medical problems by making good the loss of oestrogen in a woman’s body when menstruation is finished and her body learns to adjust.
A lack of oestrogen induces hot flushes, night sweats, thinning of the bones (osteoporosis) with possible fractures, and a wide range of physical and emotional disorders.
HRT also prevents the increased frequency of coronary disease which may follow the menopause. With oestrogen only, HRT appears to increase the incidence of cancer of the uterine body. Use of oestrogen and progestogen avoids this.
HRT is available as a tablet, transdermal patch, implant or topical cream. Most women notice temporary improvement in their appearance and hot flushes as long as treatment is continued. HRT is not prescribed by the herbal practitioner. Soya and Hops are a mild alternative.
Side-effects of such treatment include blood pressure rise, weight gain and periods probably continue with a monthly bleed. Elderly women taking HRT for osteoporosis may develop bleeding problems, the risk of blood clot and gall bladder diseases.
Helonias has proved a useful alternative, effective in eliminating excess fluids, reducing hot flushes, and relieving that bloated feeling, thus helping the older woman to live a normal life.
Damiana. 1 heaped teaspoon leaves to each cup boiling water; infuse 5-10 minutes; strain. 1 cup 2-3 times daily for 3-6 weeks.
Sarsaparilla. 1oz (30g) root in 1 pint (500ml) water; simmer gently 20 minutes; strain. 1 cup 2-3 times daily for 3-6 weeks.

Note: An extensive study of breast cancer risks with HRT revealed a positive link between the risk of cancer and length of use. Risk of the disease increased with all types of women using HRT with every year of use. Pre-menstrual women were more than twice at risk. It would appear that oestrogens cannot be taken without risk.

The term “representative”, as it is commonly used, is undefined in the statistical or mathematical sense; it means simply that the sample resembles the population in some way. The use of probability sampling will not ensure that any single sample will be “representative” of the population in all possible aspects. A common fallacy lies in the unwarranted assumption that, if the sample resembles the population closely on those factors that have been checked, it is “totally representative” and no differences exist between the sample and the universal or reference population.... representative sample

See RNA.... ribonucleic acid
Sections of deoxyribonucleic acid (DNA) – the principal molecule in a cell carrying genetic information – that act as enzymes (see ENZYME). The function of a ribozyme is to transform the messages encoded in DNA into proteins (see PROTEIN), using its property of catalysing chemical reactions in a cell. Most ribozymes act only on other pieces of ribonucleic acid (RNA), editing the messenger type that carries instructions to the parts of the cell that makes proteins. This editing ability is being used by scientists researching ways of correcting faulty GENES which can cause inherited disorders. The aim is to persuade the ribozyme to inhibit the messenger RNA to prevent production of the faulty gene. Ribozymes might also be used to disrupt infectious agents, such as viruses, which rely on RNA to invade body cells.... ribozyme
A virus disease, caused by a phlebovirus and transmitted by mosquitoes, at one time con?ned to sub-Saharan Africa and predominantly found in domestic animals such as cattle, sheep and goats. The only humans affected were veterinary surgeons, butchers and others exposed to heavy infection by direct contact with infected animals; these usually recovered. In the 1970s the disease ?ared up in Egypt, probably owing to a more virulent virus. The illness in humans is characterised by fever, haemorrhages, ENCEPHALITIS and involvement of the EYE. An e?ective vaccine protects both animals and human beings against the disease (see IMMUNISATION).... rift valley fever

Also called retinopathy of prematurity, a condition that mainly affects the eyes of premature infants. The usual cause is high concentrations of oxygen being given as part of the treatment for respiratory distress. Excess oxygen causes the tissues at the margin of the retina to shut down their blood vessels.

The use of life-saving measures of mouth-tomouth resuscitation and external cardiac compression massage in a person who has collapsed with CARDIAC ARREST. Speedy restoration of the circulation of oxygenated blood to the brain is essential to prevent damage to brain tissues from oxygen starvation. The brain is irreversibly damaged if it is starved of oxygen for more than 4–5 minutes. Someone whose heart has stopped will be very pale or blue-grey (in particular, round the lips) and unresponsive; he or she will not be breathing and will have no pulse. It is important to determine that the collapsed person has not simply fainted before starting CPR. The procedure is described under car-diac/respiratory arrest in APPENDIX 1: BASIC FIRST AID.

Cause-of-death ranking for adults is based on the List of 72 Selected Causes of Death, HIV Infection, and Alzheimer’s Disease. The List was adapted from one of the special lists for mortality tabulations recommended for use with the International Classification of Diseases, ninth revision. Two group titles – “Major cardiovascular diseases” and “Symptoms, signs, and ill-defined conditions” – are not ranked based on the list of 72 selected causes. In addition, category titles that begin with the words “other” and “all other” are not ranked. The remaining category titles are ranked according to number of deaths to determine the leading causes of death. When one of the titles that represents a subtotal is ranked (for example, unintentional injuries), its component parts are not ranked (in this case, motor vehicle crashes and all other unintentional injuries).... cause-of-death ranking

Initially driven by anxiety about the possibility of medical negligence cases, clinical risk management has evolved into the study of IATROGENIC DISEASE. The ?rst priority of risk managers is to ensure that all therapies in medicine are as safe as possible. Allied to this is a recognition that errors may occur even when error-prevention strategies are in place. Lastly, any accidents that occur are analysed, allowing a broader understanding of their cause. Risk management is generally centred on single adverse events. The threat of litigation is taken as an opportunity to expose unsafe conditions of practice and to put pressure on those with the authority to implement change. These might include senior clinicians, hospital management, the purchasing authorities, and even the Secretary of State for Health. Attention is focused on organisational factors rather than on the individuals involved in a speci?c case.... clinical risk management

When a woman is treated for infertility it is necessary to nurture human embryos for a few days (until the ?rst cell divisions of the fertilised egg have occurred) in a specialised laboratory. More eggs are fertilised than are usually needed because not all fertilisations are successful. Surplus embryos may be frozen for use in later attempts to implant an embryo in the womb. Research has been done on very early embryos but the practice is controversial and some countries have either forbidden it or imposed tight restrictions. In the UK such research is controlled by the government Human Fertilisation & Embryology Authority (see ASSISTED CONCEPTION).... embryo research

About Reishi Tea
Reishi tea is made form reishi, which is considered the best and most superior of all Chinese herbs.
Reishi is a polypore mushroom which can be found growing in dark forests, on deciduous trees and logs. It is soft, corky, and flat, and has a conspicuous red-varnished cap, kidney-shaped, and with pores underneath it. It is classified based on its color and shape, and each variety protects and nourishes a different body organ. The classification is the following: white (lungs and skin), purple (joints), red (heart), green (liver), black (brain and kidney), and yellow (spleen).
How to prepare Reishi Tea
For a cup of reishi tea, you need about 5 grams of dried reishi mushroom herbs. Add them to the necessary amount of water for one cup and boil for about 10 minutes. Then, let the mixture steep for 2-3 hours, before you strain it to remove the herbs.
If you don’t like the taste too much or you think it’s too bitter, you can add honey or fruit juice to sweeten it.

It helps by enhancing the human ability to fight abnormal cells and, consequently, it can improve the synthesis of proteins and nucleic acid. It also protects the cells against further damage, and it helps alleviate the pain and discomfort caused by chemotherapy.
Drinking reishi tea will keep the heart diseases away, as it lowers bad cholesterol levels and blood pressure. It helps strengthen the immune system, and it will also slow down the aging process by nurturing the cells in your body.
Not only is reishi tea good for your immune system, but it also helps your nervous system. This tea is bound to help you relax, by soothing the mind and sedating the nerves. It will also help you sleep properly during the night.
You can drink reishi tea if you’ve got problems with coughing or asthma. It protects your liver, therefore it is recommended to persons who suffer from acute and chronic hepatitis. Besides this, it also helps with diabetes, skin allergy, and duodenal ulcers.
Reishi Tea Side Effects
You might have an allergic reaction to reishi tea. If you end up with an upset stomach, or you feel your mouth, nose and/or throat dry, you might have an allergic reaction. Stop drinking reishi tea and contact your doctor, just in case.
Other side effects you might get when drinking reishi tea include dizziness, nosebleeds, sore bones, gastrointestinal distress, or irritated skin.
It is best not to drink reishi tea if you’re taking blood thinning medication (aspirin, warfarin). The tea might intensify the effects of the medicine. It is also considered that this tea may interfere with immunosuppressive drugs or even organ transplants.
According to the Chinese, the reishi mushroom is a plant which can bring “the dying back to life”. Reishi tea has quite similar properties too, as it comes with many health benefits. This should encourage you to drink reishi tea every day!... enjoy a cup of reishi tea!

These are drugs that block the action of HISTAMINE at the H2 receptor (which mediates the gastric and some of the cardiovascular effects of histamine). By reducing the production of acid by the stomach, these drugs – chie?y cimetidine, ranitidine, famotidine and nizatidine – are valuable in the treatment of peptic ulcers (healing when used in high dose; preventing relapse when used as maintenance therapy in reduced dose), re?ux oesophagitis (see OESOPHAGUS, DISEASES OF), and the ZOLLINGERELLISON SYNDROME. These drugs are now being supplanted by PROTON-PUMP INHIBITORS and HELICOBACTER PYLORI eradication therapy. (See also DUODENAL ULCER.)... h2 receptor antagonists
It you want to drink a special type of herbal tea, try the rose petal tea. It is aromatic, with a pleasant taste, and you’re bound to enjoy it. It also has important health benefits. Find out more about rose petal tea!
About Rose Petal Tea
Rose petal tea is made from the petals of a flower most adored by many women: the rose. This woody perennial plant has over 100 species which grow in Asia, Europe, North America, and northwest Africa.
Roses grow as a group of erect shrubs, acting like climbing plants. Its stems often have small, sharp thorns. The leaves are oval-shaped with sharply-toothed edges, and they’re about 10cm long. The fruit is called rosehip; it is ripe from late summer to autumn, and it is edible. The flowers usually have 5 petals with two distinct lobes; they are usually pink, white, red, or yellow.
You can make tea both from the rose petals and from the rose’s fruit, the rosehip.
How to prepare Rose Petal Tea
When making rose petal tea, first make sure that the petals you use are free of pesticides. Roses from gardens and flower shops are usually treated with pesticides, and shouldn’t be used to make rose petal tea.
To enjoy rose petal tea, add about two handfuls of properly washed and dry rose petals to a pot with water for three cups of tea. Leave the pot over medium heat for 5 minutes, or until the petals have lost their original color, becoming darker. Stream to remove the petals and sweeten, if necessary, with honey or fruit juice.
Rose Petal Tea Components
Rose petal tea gets many active components from the rose petals: cyclic monoterpene alcohols, geraniol, citronellol and nerol are just a few important ones. It also includes long-chain hydrocarbons (nonadecane, heneicosane).
These active components lead to the many health benefits rose petal tea has.
Rose Petal Tea Benefits
Rose petal tea helps strengthen your immunity, and can be part of the treatment for colds. It is useful if you’ve got a fever, a runny nose, a sore throat, or bronchial congestion. Also, it helps clean your body of toxins.
Drinking rose petal tea can help during menstrual periods, if you’ve got a heavy menstrual flow. It can also reduce menstrual cramps, and helps regulate your period.
Rose petal tea is often used to treat diarrhea and dysentery. It can also help you fight against depression, fatigue and insomnia.
Rose petal tea also acts as a digestive aid, as it protects the gastrointestinal tract. It is often used to treat constipation, gastroenteritis, diarrhea, and dysentery; the tea also nourishes the gastric mucosa. You can drink rose petal tea to treat urinary tract infections, as well.
Rose Petal Tea Side Effects
No important side effects of rose petal tea have been noted. Still, it is considered best not to drink more than 5 cups of tea a day. If you drink too much, you might get some of these symptoms: headaches, loss of appetite, vomiting, diarrhea, insomnia, dizziness, and irregular heartbeats.

Each of the two KIDNEYS ?lters a large volume of blood – 25 per cent of cardiac output, or around 1,300 ml – through its two million glomeruli (see GLOMERULUS) every minute. The glomeruli ?lter out cell, protein, and fat-free ?uid which, after reabsorption of certain chemicals, is excreted as urine. The rate of this ultra?ltration process, which in health is remarkably constant, is called the glomerular ?ltration rate (GFR). Each day nearly 180 litres of water plus some small molecular-weight constituents of blood are ?ltrated. The GFR is thus an indicator of kidney function. The most widely used measurement is CREATININE clearance and this is assessed by measuring the amount of creatinine in a 24-hour sample of urine and the amount of creatinine in the plasma; a formula is applied that gives the GFR.... glomerular filtration rate (gfr)

These drugs reduce the amount of low-density LIPOPROTEINS, which transport CHOLESTEROL and triglycerides (see TRIGLYCERIDE) in the blood, or raise the concentration of high-density lipoproteins. The aim is to reduce the progression of ATHEROSCLEROSIS and therefore help prevent coronary heart disease (see HEART, DISEASES OF). These drugs should be combined with reducing other risk factors for raised lipid concentrations, such as a high-fat diet, smoking and obesity.

Ayurvedic: Akshoda, Akshoda- ka, Akshota, Shailbhava, Pilu, Karparaal, Vrantphala.
Unani: Akhrot.
Siddha/Tamil: Akrottu.
Action: Leaves and bark— alterative, laxative, antiseptic, mild hypoglycaemic, anti-inflammatory, antiscrofula, detergent. An infusion of leaves and bark is used for herpes, eczema and other cutaneous affections; externally to skin eruptions and ulcers. Volatile oil— antifungal, antimicrobial.
Key application (leaf) ? In mild, superficial inflammation of the skin and excessive perspiration of hands and feet. (German Commission E.). When English Walnuts (Juglans regia) are added to low fat diet, total cholesterol may be decreased by 412% and LDL by 8-16%. (Natural Medicines Comprehensive Database, 2007.)Walnut hull preparations are used for skin diseases and abscesses.Walnut is eaten as a dry fruit. Because of its resemblance to the brain, it was thought, according to the "doctrine of signatures", to be a good brain tonic. Walnuts are also eaten to lower the cholesterol levels.From the volatile oil of the leaves terpenoid substances (monoterpenes, sesquiterpenes, diterpene and triter- pene derivatives) and eugenol have been isolated. Fatty acids, including geranic acid; alpha-and beta-pinene, 1,8,cincole, limonene, beta-eudesmol and juglone are also important constituents of the volatile oil.The leaves contain napthoquinones, mainly juglone. The root bark gave 3, 3',-bis-juglone and oligomeric ju- glones. Unripe fruit husk also gave napthoquinones.The kernels of Indian walnuts contain 15.6% protein, 11% carbohydrates, 1.8% mineral matter (sodium, potassium, calcium, magnesium, iron, copper, phosphorus, sulphur and chorine). Iodine (2.8 mcg/100 g), arsenic, zinc, cobalt and manganese are also reported. Kernels are also rich in vitamins of the B group, vitamin A (30 IU/100 g), and ascorbic acid (3 mg/100 g).The juice of unripe fruits showed significant thyroid hormone enhancing activity (prolonged use of such extract may cause serious side effect).White Walnut, Lemon Walnut, Butternut, Oilnut of the USA is equated with Juglans cineraria L. The inner bark gave napthoquinones, including juglone, juglandin, juglandic acid, tannins and an essential oil.Butternut is used as a dermatologi- cal and antihaemorrhoidal agent.

Most staphylococci (see STAPHYLOCOCCUS) have now evolved resistance to benzylpenicillin (see PENICILLIN) because of their ability to produce PENICILLINASE. Cloxacillin and ?ucloxacillin are antibiotics still e?ective against most staphylococci; at one time methicillin was used to combat resistant strains, but in hospital environments bacteria acquired immunity to this powerful drug (now withdrawn from use) and to cloxacillin. RIFAMPICIN, VANCOMYCIN, TEICOPLANIN and temocillin are still active against most penicillinase-producing gram-negative bacteria (see GRAM’S STAIN). There is, however, a growing threat to health because of the rise in the number of antibiotic-resistant bacteria, particularly in hospitals. The bacteria themselves are not more virulent than others, but the di?culty in treating them with a safe and e?ective antibiotic mean that they are more dangerous. It is likely that lapses in normal hygienic practice – such as frequent hand-washing – has resulted in an increase in MRSA disease.... methicillin-resistant staphylococcus aureus (mrsa)
These drugs produce partial or complete paralysis of skeletal muscle (see under MUSCLE – Structure of muscle). Drugs in clinical use are all reversible and are used to help insert a breathing tube into the TRACHEA (endotracheal tube) during general ANAESTHESIA and ARTIFICIAL VENTILATION OF THE LUNGS. They may be broadly divided into depolarising and nondepolarising muscle relaxants. Depolarising muscle relaxants act by binding to acetylcholine receptors at the motor end-plate where nerves are attached to muscle cells, and producing a more prolonged depolarisation than acetylcholine, which results in initial muscle fasciculation (overactivity) and then ?accid paralysis of the muscle. The only commonly used depolarising drug is succinylcholine which has a rapid onset of action and lasts approximately three minutes. Non-depolarising muscle relaxants bind to the acetylcholine receptors, preventing acetylcholine from gaining access to them. They have a slower onset time and longer duration than depolarisers, although this varies widely between di?erent drugs. They are competitive antagonists and they may be reversed by increasing the concentration of acetylcholine at the motor end-plate using an anticholinesterase agent such as neostigmine. These drugs are broken down in the liver and excreted through the kidney, and their action will be prolonged in liver and renal failure. Other uses include the relief of skeletal muscle spasms in TETANUS, PARKINSONISM and spastic disorders. The drugs dantrolene and diazepam are used in these circumstances.... muscle relaxants

Pleurisy root tea is an aromatic herbal tea which you are bound to enjoy. The indigenous Indians used to drink it a lot, especially thanks to its health benefits.
About Pleurisy Root Tea
Pleurisy root tea is made from the roots of the pleurisy plant, also known as the butterfly weed. The plant grows in North America.
It can grow up to 1m tall, with multiple stems and spirally-arranged, spear-pointed leaves that are 5-12cm long. Clusters of orange or yellow flowers bloom during summertime, attracting butterflies, insects and birds. The plant can be found growing on dry, open fields, under direct sunlight.
How to prepare Pleurisy Root Tea
If you want to enjoy a cup of pleurisy root tea, add a teaspoon of dried, chopped roots to a cup of freshly boiled water. Let it steep for 10-15 minutes before straining it to remove the herbs. Sweeten it with honey or fruit juice, if necessary.
Pleurisy Root Tea Benefits
Pleurisy root contains various active constituents, such as glycosides, resins, amino acids, volatile oil, glucosidal principal, lupeol, and alkaloids. They are transferred to the pleurisy root tea, as well. Because if this, the tea has lots of important health benefits.
Pleurisy root tea is often included in treatments for various respiratory ailments and pulmonary infections, for example pleurisy, asthma, bronchitis or pneumonia. It helps alleviate pain and congestion by reducing the mucus thickness in the lungs and enabling the patient to expel the blockage.
Drinking pleurisy root tea helps both with fevers and detoxification, as it stimulates sweating and perspiration. It is also useful as an herbal treatment for colds and influenza.
You can also drink pleurisy root tea if you’ve got problems with diarrhea, dysentery, chronic rheumatism, colic, muscle tension and spasm.
Pleurisy root tea can also be used topically. You can soak a clean cloth with the tea and use it to treat swellings, bruises, lameness, wounds and skin ulcers.
Pleurisy Root Tea Side Effects
If you’re pregnant, you shouldn’t drink pleurisy root tea. It may cause uterine contractions, which could lead to miscarriages. Also, it is safer not to drink this tea if you’re breast feeding. Children shouldn’t drink pleurisy root tea either, because of the small amount of cardiac glycosides.
You should be careful with the amount of pleurisy root tea you drink if you’ve got cardiovascular problems or you’re taking cardiac glycosides. Also, if you’re taking any other medication, check with your doctor if it’s safe to drink pleurisy root tea.
Don’t drink more than 3-4 cups of pleurisy root tea a day. If you drink too much, it might lead to symptoms such as intestinal cramping, nausea, vomiting, and diarrhea.
Pleurisy root tea is ideal for an everyday beverage. It has many health benefits and only a few side effects. Once you try it, you’ll surely enjoy it!... pleurisy root tea - tea of the indigenous indians

Synonym: Drypetes roxburghii (Wall.) Hurusawa.Family: Euphoriaceae.
Habitat: Throughout tropical India, wild and cultivated as an avenue tree.English: Child-life tree, Indian Amulet Plant, Spurious Wild Olive.Ayurvedic: Putranjiva, Putrajivaka, Putrajiva, Yashtipushpa, Arth- saadhanaSiddha/Tamil: Karupali Garbhadaa and Garbhakaraa are misleading synonyms.Folk: Jiyaapotaa.
Action: Fruit—powered (deseeded) fruits are used against cough, cold and sprue. Rosaries of hard stones are used for protecting children from infections. (Due to misleading nomenclature, the "conception-promoting" property has been attributed to the drug in folk medicine. Its use is possible in vaginal infections and genitourinary diseases, or skin eruptions during pre-conception stage.)The seed kernel on steam distillation yield 0.5% of a sharp-smelling essential oil of the mustard oil type. The oil contains isopropyl and 2-butyl isothio- cyanates as the main constituents and 2-methyl-butyl isothiocyanate as a minor component. The iso-thiocyanates are produced on enzymic hydrolysis of glycosidic progenitors present in the kernels, viz. glucoputranjivin, gluco- cochlearin and glucojiaputin respectively. An additional glucoside, gluco- cleomin has been identified in the seed kernel, it affords a non-volatile mustard oil, cleomin. A glycosidic pattern similar to that in the seed is reported in the shoots and roots.The fruit pulp contains a large proportion of mannitol and small quantities of saponin glucosides and alkaloids.The seed coat gave putranjivoside, putranoside A, B, C and D, beta- sitosterol and tis beta-D-glucoside.The leaves gave amentoflavone and its derivatives, beta-amyrin and its palmite, polyphenols, putranjiva sa- ponin A,B,C, and D and stigmasterol.The bark contains friedelin, friede- lanol, friedelanone, friedelan-3,7-di- one (putranjivadione), 3-alpha-hydro- xy friedelan- 7-one (roxburgholone), carboxylic acid, putric acid, putran- jivic acid.The essential oil from leaves showed mild antifungal activity against Rhizoctonia solani.

Poir.
Synonym: R. spinosa Poir. R. brandisii Gamble. R. longispina W. & A. R. tomentosa W. & A. non Blume. Xeromphis spinosa Keay.
Habitat: Assam, Naga and Khasi Hills, Travancore and the Andamans.
English: Common Emetic Nut.
Ayurvedic: Madana, Chhardana, Pindi, Shalayaka, Vishapushpaka.
Unani: Mainphal, Jauz-ul-Qai.
Siddha/Tamil: Marukkaaraikai, Madkarai.
Folk: Mainphal.
Action: Fruit—nervine, calmative, antispasmodic, emetic, anthelmintic, abortifacient. Used as a substitute for ipecacuanha.
The Ayurvedic Pharmacopoeia ofIn- dia recommends the dried fruit in chlorosis, common cold, rhinitis and obstinate skin diseases.The activity of the drug is attributed to the presence of saponins which occur to the extent of 2-3% in fresh fruits and about 10% in dried whole fruit. The saponins are concentrated mostly in the pulp. A mixture of two saponins, viz. randialic or neutral saponin and randialic acid or acid saponin has been isolated from the pulp. On complete hydrolysis both the saponins yield oleanolic acid as sapogenin. Ursosaponin, isolated from the ethanolic extract of the dried whole fruit, gave ursolic acid and glucose. Randianin, isolated from the fruit, gave a haemolytic triterpe- noid saponin.In experimental animals, the drug caused haemolysis both in vitro and in vivo. Crude saponin fraction showed haemolytic, molluscidal and immuno- stimulating activities.Oleanolic acid 3-glucoside, isolated from the seed, exhibited anti-arthritic activity in exudative and proliferative phases of inflammation in rats.
Dosage: Fruit—0.5-1.0 g powder for decoction, 3-6 g for induction vomiting. (API, Vol. I.)... randia dumetorum

The tendency for the estimated magnitude of a parameter (e.g. based upon the average of a sample of observations of a treatment or intervention effect) to deviate randomly from the true magnitude of that parameter. Random variation is independent of the effects of systematic biases. In general, the larger the sample size, the lower the random variation of the estimate of a parameter. As random variation decreases, precision increases.... random variation / random error
A method of comparing the results between two or more groups of patients intentionally subjected to di?erent methods of treatment – or sometimes of prevention. Those subjects entering the trial have to give their informed permission. They are allocated to their respective groups using random numbers, with one group (controls) receiving no active treatment, instead receiving either PLACEBO or a traditional treatment. Preferably, neither the subject nor the assessor should know which ‘regimen’ is allocated to which subject: this is known as a double-blind trial.... randomised controlled trial

Linn.
Family: Cruciferae; Brassicaceae.
Habitat: Cultivated in Uttar Pradesh, Punjab, Maharashtra and Gujarat.
English: Radish.
Ayurvedic: Muulaka, Laghu- muulaka, Muulakapotikaa, Visra, Shaaleya, Marusambhava. Pods— Sungraa, Singri, Mungraa.
Unani: Muuli, Turb Fajal.
Siddha/Tamil: Mullangi.
Action: Radish—preparations are used in liver, gallbladder and urinary complaints. Green leaves— diuretic and carminative. Seeds— diuretic, purgative, expectorant.
A decoction of dry radish is given orally in piles. Extract of the dry root is given for hiccough, influenza, dysentery, colic and urinary troubles.
Key application: In peptic disorders, especially those related to dyskinesia of the bile ducts; and in catarrhs of the upper respiratory tract. (German Commission E.)The Ayurvedic Pharmacopoeia of India recommends the juice of the whole plant in sinusitis; juice of the root in diseases of the throat and sinusitis; and the seed in amenorrhoea, cough and dyspnoea.The fleshy root and seeds contain trans-4-methyl-thiobutenyl isothio- cyanate glucoside (the pungent principle), cyanidin-5-glucoside-3-sophoro- side, pelargonidin diglycoside, cyani- din diglycoside, 5-methyl-L-cysteine- sulphoxide (methiin), steroidal sa- pogenins and sulphorophene.The enzymes present in the radish are phosphatase, catalase, sucrase, amylase, alcohol dehydrogenase and pyruvic carboxylase.Radish contains caffeic acid and fer- ulic acid which exhibit hepatoprotec- tive and choleretic properties. It contains choline which prevents deposition of fat in liver. Amino acids, or- nithine, citrulline, arginine, glutamic acid and asparatic acid remove toxins from the body and urea acumulation.Radish is a good source of ascorbic acid (15-40 mg/100 g), trace elements include aluminium, barium, lithium, manganese, silicon, titanium, also iodine (upto 18 mcg/100 g) and ascor- bigen.Roots, leaves, flowers and pods are active against Gram-positive bacteria.The seeds are reported to contain a broad spectrum antibiotic, machro- lysin, specific against Mycobacterium tuberculosis. Raphanin, extracted from the seeds, is active against Grampositive and Gram-negative bacteria.A purified basic protein, homologous to nonspecific lipid transfer proteins, from seeds showed antifungal activity.Raphanus caudatus Linn., synonym R. sativus var. caudatus, is known as Rat-Tail Radish.A native to Java, it is cultivated in northern and western India. The root is not used; pods, purple or violet in colour, are consumed for properties attributed to Raphanus sp. These are known as Mungraa or Sungraa.
Dosage: Whole plant-20-40 ml juice; root—15-30 ml juice. (API, Vol. II.) Seed—1-3 g powder. (API, Vol. III.)... raphanus sativus

Calamus speciesDescription: The rattan palm is a stout, robust climber. It has hooks on the midrib of its leaves that it uses to remain attached to trees on which it grows. Sometimes, mature stems grow to 90 meters. It has alternate, compound leaves and a whitish flower.Habitat and Distribution: The rattan palm is found from tropical Africa through Asia to the East Indies and Australia. It grows mainly in rain forests.Edible Parts: Rattan palms hold a considerable amount of starch in their young stem tips. You can eat them roasted or raw. In other kinds, a gelatinous pulp, either sweet or sour, surrounds the seeds. You can suck out this pulp. The palm heart is also edible raw or cooked.Other Uses: You can obtain large amounts of potable water by cutting the ends of the long stems (see Chapter 6). The stems can be used to make baskets and fish traps.... rattan palm

Benth. ex Kurz.
Family: Apocynaceae.
Habitat: The sub-Himalayas tract from Punjab to Nepal, Sikkim, Bhutan, Assam, Western Ghats and the Andamans.
English: Rauvolfia root, Serpentina Root, Indian Snakeroot.
Ayurvedic: Sarpagandhaa of Ayurvedic texts was not the Sarpagandhaa of modern medicine. (Sarpagandhaa was equated with Naakuli, Sarpach- hatrikaa and Varshaasu Chha- trikaaraa. Sarpagandhaa and Sarpasugandhaa were synonyms of Naakuli.)
Folk: Chhotaa Chaand.
Action: Root—decoction is employed to increase uterine contractions and for expulsion of foetus in difficult cases. The total alkaloidal extract of the root induces bradycardia, hypotension, sedation. It finds application in hypochondria, neuropsychi- atric disorders, psychosis and schizophrenia.
Key application: In mild, essential hypertension (borderline hypertension, especially with elevated tension of the sympathetic nervous system, for example, sinus tachycardia, anxiety, tension and psychomotor irritation, when dietetic measures alone are not sufficient. (German Commission E.)(Average daily dose: 600 mg drug corresponding to 6 mg total alkaloid.) Treatment is usually administered with a diuretic to prevent fluid retention which may develop if Rauvolfia root is given alone. (WHO.) Contraindicated in depression, bleeding disorders, gastric and duodenal ulcers. (Sharon M. Herr.) Also contraindicated in pregnancy, since it has both teratogenic and abortifacient potential. (Francis Brinker.)The root and root bark are rich in alkaloids, the most important being reserpine, others, around 30, which include ajmaline, ajmalicine (raubasine), ajmalicine, yohimbine, coryanthine, iso-ajmaline, neo-ajmaline, papaver- ine, raubasine, rauwolscine, rescin- namine, reserpine, sarpagine, serpentine, serpentinine, serpinine and de- serpidine.Reserpine is hypotensive and tranquilizer, used for certain forms of mental disorders. Ajmalicine (raubasine) and rescinnamine are also hypoten- sive and tranquilizer. Deserpidine is sedative, as well as hypotensive. Aj- maline exhibits antiarrhythmic activity.A number of Rauvolfia species are found in India: R. beddomei Hook. f.; R. densiflora Benth ex Hook. f. (Himalayas, Khasi and Aka Hills; Western and Eastern Ghats); R. micrantha Hook. f; known as Malabar Rauvolfia, (Kerala, up to an altitude of 300 m)The roots of R. beddomei contain ajmalicine, sarpagine and serpentine, but no reserpine. R. densiflora yielded 0.51% of total alkaloids (reserpine 0.01%). R. micrantha gave ajmalicine, raunamine, reserpiline, sarpagine, neosarpagine, in addition to reserpine.(In classical Ayurvedic texts, Nakuli and Gandha-naakuli were included in compound formulations for mental diseases.)... rauvolfia serpentina

These form an agreed UK thesaurus of health-care terminology named after the general practitioner who devised them initially in the 1970s. The coding system provides a basis for computerised clinical records that can be shared across professional and administrative boundaries. Such records have essential safeguards for security and con?dentiality. The codes accommodate the di?erent views of specialists, but use simple terms without any loss of the ?ne detail necessary in specialist terminology. The Read Codes are being merged with the world’s other leading coding and classi?cation system: the College of American Pathologists’ Systemised Nomenclature of Medicine (SNOMED-RT).... read codes

As used by immunologists, this term refers to IgE antibodies. As used by microbiologists, it refers to antibodies produced in syphilis – probably in response to the tissue damage caused by Treponema pallidum. Production of these antibodies in patients with syphilis has been utilised in the development of the non-treponemal serological tests for syphilis such as the VDRL Test, the RPR Test and the now superceded Wasserman Complement Fixation Test. These tests are useful in that they are only positive in active syphilis but they have many biological false positive reactions, including pregnancy.... reaginic antibody

Reconstructive surgery on the skin and underlying tissues that have been damaged or lost as a result of disease or injury. Congenital malformations are also remedied using reconstructive surgery. Surgeons graft healthy skin from another part of the body to repair skin damaged or destroyed by burns or injuries. New techniques are under development for growing new skin in the laboratory to be used in reconstructive surgery. Surgeons also repair damage using skin ?aps prepared in another part of the body – for example, a skin ?ap from the arm may be used to repair a badly injured nose or face. Reconstructive surgery is also used to repair the consequences of an operation for cancer of, say, the neck or the jaw. Plastic surgeons undertake cosmetic surgery to improve the appearance of noses, breasts, abdomens and faces.... reconstructive (plastic) surgery

The following are described under their separate dictionary entries: FAECES; HAEMORRHOIDS; FISTULA; DIARRHOEA; CONSTIPATION.
Imperforate anus, or absence of the anus, may occur in newly born children, and the condition is relieved by operation.
Itching at the anal opening is common and can be troublesome. It may be due to slight abrasions, to piles, to the presence of threadworms (see ENTEROBIASIS), and/or to anal sex. The anal area should be bathed once or twice a day; clothing should be loose and smooth. Local application of soothing preparations containing mild astringents (bismuth subgallate, zinc oxide and hamamelis) and CORTICOSTEROIDS may provide symptomatic relief. Proprietary preparations contain lubricants, VASOCONSTRICTORS and mild ANTISEPTICS.
Pain on defaecation is commonly caused by a small ulcer or ?ssure, or by an engorged haemorrhoid (pile). Haemorrhoids may also cause an aching pain in the rectum. (See also PROCTALGIA.)
Abscess in the cellular tissue at the side of the rectum – known from its position as an ischio-rectal abscess – is fairly common and may produce a ?stula. Treatment is by ANTIBIOTICS and, if necessary, surgery to drain the abscess.
Prolapse or protrusion of the rectum is sometimes found in children, usually between the ages of six months and two years. This is generally a temporary disorder. Straining at defaecation by adults can cause the lining of the rectum to protrude outside the anus, resulting in discomfort, discharge and bleeding. Treatment of the underlying constipation is essential as well as local symptomatic measures (see above). Haemorrhoids sometimes prolapse. If a return to normal bowel habits with the production of soft faeces fails to restore the rectum to normal, surgery to remove the haemorrhoids may be necessary. If prolapse of the rectum recurs, despite a return to normal bowel habits, surgery may be required to rectify it.
Tumours of small size situated on the skin near the opening of the bowel, and consisting of nodules, tags of skin, or cauli?ower-like excrescences, are common, and may give rise to pain, itching and watery discharges. These are easily removed if necessary. Polypi (see POLYPUS) occasionally develop within the rectum, and may give rise to no pain, although they may cause frequent discharges of blood. Like polypi elsewhere, they may often be removed by a minor operation. (See also POLYPOSIS.)
Cancer of the rectum and colon is the commonest malignancy in the gastrointestinal tract: around 17,000 people a year die from these conditions in the United Kingdom. Rectal cancer is more common in men than in women; colonic cancer is more common in women. Rectal cancer is a disease of later life, seldom affecting young people, and its appearance is generally insidious. The tumour begins commonly in the mucous membrane, its structure resembling that of the glands with which the membrane is furnished, and it quickly in?ltrates the other coats of the intestine and then invades neighbouring organs. Secondary growths in most cases occur soon in the lymphatic glands within the abdomen and in the liver. The symptoms appear gradually and consist of diarrhoea, alternating with attacks of constipation, and, later on, discharges of blood or blood-stained ?uid from the bowels, together with weight loss and weakness. A growth can be well advanced before it causes much disturbance. Treatment is surgical and usually this consists of removal of the whole of the rectum and the distal two-thirds of the sigmoid colon, and the establishment of a COLOSTOMY. Depending upon the extent of the tumour, approximately 50 per cent of the patients who have this operation are alive and well after ?ve years. In some cases in which the growth occurs in the upper part of the rectum, it is now possible to remove the growth and preserve the anus so that the patient is saved the discomfort of having a colostomy. RADIOTHERAPY and CHEMOTHERAPY may also be necessary.... rectum, diseases of

Granulation is the forming of connective tissue fibroblasts, epithelium and inflammatory cells around the nucleus of new capillaries in tissues that have been burned or scraped. This delicate tissue is often reinjured, and regranulation becomes a slower process, with more formation of scar tissue. Some plant resins will quickly stimulate the process, increase the complexity of healing, and lessen fibroblast scar formation.... regranulation

Professional sta? working in health care are registered with and regulated by several statutory bodies: doctors by the GENERAL MEDICAL COUNCIL (GMC); dentists by the GENERAL DENTAL COUNCIL; nurses and midwives by the Council for Nursing and Midwifery, formerly the UK Central Council for Nursing, Midwifery and Health Visiting (see NURSING); PHARMACISTS by the Royal Pharmaceutical Society; and the professions supplementary to medicine (chiropody, dietetics, medical laboratory sciences, occupational therapy, orthoptics, physiotherapy and radiography) by the Council for Professions Supplementary to Medicine. In 2002, the Council for the Regulation of Health Care Professions was set up as a statutory body that will promote cooperation between and give advice to existing regulatory bodies, provide a quality-control mechanism, and play a part in promoting the interests of patients. The new Council is accountable to a Select Committee of Parliament and is a non-ministerial government department similar in status to the FOOD STANDARDS AGENCY. It has the right to scrutinise the decisions of its constituent bodies and can apply for judicial review if it feels that a judgement by a disciplinary committee has been too lenient.... regulation of health professions

A condition probably caused by an immunological response to a virus (see IMMUNITY), in which the patient has URETHRITIS, ARTHRITIS and conjunctivitis (see under EYE, DISORDERS OF). The skin may also be affected by horny areas which develop in it. The disorder was ?rst described by a German physician, H. Reiter (1881–1969); it is more common in men than in women, and is the most common cause of arthritis in young men. It usually develops in people who have a genetic predisposition for it: around 80 per cent of sufferers have the HLA B27 tissue type. Treatment is symptomatic with ANALGESICS and NON-STEROIDAL ANTIINFLAMMATORY DRUGS (NSAIDS). (See also REACTIVE ARTHRITIS.)... reiter’s syndrome

The idea of a marriage-guidance council came from a group of doctors, clergy and social workers who were concerned for the welfare of marriage. It is based upon two major concepts: that marriage provides the best possible way for a man and woman to live together and rear their children; and that the counsellors share a basic respect for the unique personality of the individual and his (or her) right to make his (or her) own decisions. The organisation consists of between 120 and 130 Marriage Guidance Councils throughout the country, comprising about 1,250 counsellors. These Councils are a?liated to Relate National Marriage Guidance, which is responsible for the selection, training and continued supervision of all counsellors. Anyone seeking help can telephone or write for an appointment. No fees are charged, but those receiving help are encouraged to donate what they can.... relate marriage guidance

Research misconduct is de?ned as behaviour by a researcher that falls short of good ethical and scienti?c standards – whether or not this be intentional. For example, the same data may be sent for publication to more than one medical journal, which might have the e?ect of their being counted twice in any META-ANALYSIS or systematic review; or the data may be ‘salami sliced’ to try to make the maximum number of publications, even though the data may overlap. Fraud in the context of research is de?ned as the generation of false data with the intent to deceive. It is much less frequent than carelessness, but its incidence is estimated as between
0.1 and 1 per cent. A ?gure of 1 per cent means that, in the United Kingdom at any one time, maybe 30 studies are being conducted, or their results published, which could contain false information. Examples include forged ethics-committee approval, patient signatures and diary cards; fabricated ?gures and results; invention of non-existent patient subjects; or sharing one electrocardiogram or blood sample amongst many subjects.
Research fraud should be ?rst suspected by a clinical-trial monitor who recognises that data are not genuine, or by a quality-assurance auditor who cannot reconcile data in clinical-trial report forms with original patient records. Unfortunately, it often comes to light by chance. There may be suspicious similarities between data ostensibly coming from more than one source, or visits may have been recorded when it was known that the clinic was shut. Statistical analysis of a likely irregularity will frequently con?rm such suspicion. The motivation for fraud is usually greed, but a desire to publish at all costs, to be the original author of a medical breakthrough, to bolster applications for research grants, or to strengthen a bid for more departmental resources are other recognised reasons for committing fraud.
In the USA, those proved to have committed fraud are debarred from receiving federal funds for research purposes or from undertaking government-funded therapeutic research. The four Nordic countries (Denmark, Finland, Norway and Sweden) have committees on research dishonesty that investigate all cases of suspected research misconduct. In the United Kingdom, an informal system operated by the pharmaceutical industry, using the disciplinary mechanism of the General Medical Council (GMC), has led to more than 16 doctors in the past ten years being disciplined for having committed research fraud. Editors of many of the world’s leading medical journals have united to form the Committee on Publishing Ethics, which advises doctors on proper practice and assists them in retracting or refusing to publish articles found or known to be false. (See ETHICS; ETHICS COMMITTEES.) Where an author does not o?er a satisfactory explanation, the matter is passed to his or her institution to investigate; where an editor or the committee is not satis?ed with the result they may pass the complaint to the appropriate regulatory body, such as the GMC in Britain.... research fraud and misconduct

The sum total of body mechanisms which interpose barriers to the progress of invasion or multiplication of infectious agents, or to damage by their toxic products. 1. Immunity - That resistance usually associated with possession of antibodies having a specific action on the microorganism concerned with a particular infectious disease or on its toxin. Passive immunity is attained either naturally, by maternal transfer, or artificially, by inoculation of specific protective antibodies (convalescent or immune serum or immune serum (gamma) globulin (human) and is of brief duration (days to months). Active immunity lasting months to years is attained either naturally, by infection, with or without clinical manifestations, or artificially, byinoculation of fractions or products of the infectious agent or of the agent itself, in killed, modified or variant form. 2. Inherent resistance - An ability to resist disease independently of antibodies or of specifically developed tissue response; it commonly rests in anatomic or physiologic characteristics of the host; it may be genetic or acquired, permanent or temporary.... resistance (host)
A new hormone (see HORMONES) recently identi?ed by researchers in the United States. It links OBESITY to type 2 diabetes (see DIABETES MELLITUS – Non-insulin dependent diabetes mellitus (NIDDM)) and its name is based on its action – namely, resistance to INSULIN. This resistance is a hallmark of this type of diabetes and is manifested throughout the body. THIAZOLIDINEDIONE DRUGS, a new class of antidiabetic drugs that lower insulin resistance, are mediated by receptors which are abundant in fat cells, and the researchers claim to have identi?ed a fat-cell PROTEIN that may be responsible for this and which they believe to be a hormone; it was also found in high concentrations in diabetic mice.... resistin

DC.
Synonym: Frangulapurshiana (DC) A. Grey.
Family: Rhamnaceae.
Habitat: Native to Europe; introduced in Kashmir, Himachal Pradesh, Bhutan and the Nilgiris.
English: Buckthorn (related species), Cascara Sagrada, Sacred Bark.
Action: Bark—stool-softener, non-habit forming stimulant laxative, pancreatic stimulant. Used for dyspepsia and habitual constipation.
Key application: In occasional constipation. (German Commission E, ESCOP, WHO.) As a stimulant laxative. (The British Herbal Pharmacopoeia.)The bark contains up to 10% an- thraquinone glycosides, consisting of the cascarosides A, B, C and D, about 70% of the total; other glycosides in minor concentrations include barbaloin, frangulin, chrysanol, glycosides based on emodin, aloe-emodin, emodin- oxanthrone and chrysophanol; dianthrones, and free aglycones.The cascarosides act on large intestines and stimulate peristalsis. The emodin exhibits antispasmodic activity in isolated rat intestine. Its anti- inflammatory and antiseptic action was also demonstrated.Rhamnus catharticus Linn., is equated with common Buckthorn, R. purpurea Edgew. with Purple Buckthorn. R. purpurea is found in the Himalayas from Kashmir to Nepal.Dried bark of Rhamnus frangula L. (Alder Buckthorn) and dried ripe berries of Ramnus catharticus are also used against constipation. (German Commission E, WHO.)Long term use or excessive amounts may cause albuminuria, haematuria, slowing ofintestinal transit and cardiac irregularities. (Sharon M. Herr.)Rhamnus triquetra Brandis (known as Gudlei, Fagoraa, Gardhan in Punjab; Gaunt in Garhwal and Kumaon and Katheraa in Jaunsar) is found in the Himalayas from Kashmir to Nepal. The bark is used as a tonic, astringent and deobstruent. Kaempferol, its 7-O- methyl ether and 4'-O-methyl ether, physcion-8 beta-D-glucoside, emodin and its 8 beta-D-glucoside were isolated from the whole plant. Emodin exhibited CNS depressant activity. (Fi- toterapia, 65, 1994.) The plant exhibited significant anti-inflammatory and a nonspecific antispasmodic activity. It induced cardio-stimulation which might be due to the endogenous release of catecholamines.Rhamnus napalensis Wall. ex M. Laws. (known as Archal in Nepal; Biringa and Birringguli in Assam) is found in eastern Himalayas and the hills and plains ofAssam, Bihar, Orissa, Madhya Pradesh and northern Andhra Pradesh, ascending up to an altitude of 2,000 m.

Wall. ex Meissn.
Synonym: R. australe D. Don.
Family: Polygonaceae.
Habitat: Sub-alpine Himalayas, from Kashmir to Sikkim at altitudes of 3,300-5,200 m.; also cultivated in Assam.
English: Indian Rhubarb, Himalayan Rhubarb.
Ayurvedic: Amlaparni, Pitamuuli, Gandhini Revatikaa. Revandachini (roots).
Unani: Revandchini.
Siddha/Tamil: Revalchinikattai, Nattirevaichini.
Action: Purgative, astringent, aperient. Used for constipation and atonic dyspepsia. Not advised for patients suffering from gout, rheumatism, epilepsy. (When given internally, the root imparts a deep tinge to the urine.)
The root gave emodin, emodin- 3-monomethyl ether, chrysophanol, aloe-emodin, rhein. These occur free and as quinone, anthrone or dianthrone glycosides. The astringent principle consists of gallic acid together with small amounts of tannin. The drug also contain cinnamic and rhe- inolic acids, volatile oil, starch and calcium oxalate. Two major glyco- sidic active principles, sennoside A and B, are present along with free an- thraquinones.At low doses, the tannin exerts astringent effect and relieves diarrhoea; at higher doses anthraquinones stimulate laxative effect and relieve constipation. (Natural Medicines Comprehensive Database, 2007.)There are three main types of rhubarbs—Chinese, Indian or Himalayan, and Rhapontic.The Chinese rhubarb consists of the rhizomes and roots of Rheum palma- tum and R. officinale.The Indian rhubarb consists of dried rhizomes of R. emodi and R. web- bianum; rhizomes and roots of R. moorcroftianum and R. spiciforme are also reported to be mixed with the drug. R. rhaponticum is the Rhapontic rhubarb.Rheum moorcroftianum Royle (the Himalayas at altitudes of 3,0005,200 m., chiefly in Garhwal and Ku- maon) possesses properties similar to those of R. emodi and the roots are mixed with the latter.Rheum spiciforme Royle (drier ranges of Kumaon and Sikkim at altitudes of 2,700-4,800 m.) also possesses purgative properties. The rhizomes and roots are mixed up with Himalayan rhubarb.Rheum webbianum Royle (the western and central Himalayas at altitudes of 3,000-5,000 m.) is the source of Himalayan rhubarb.Rheum palmatum is esteemed as the best type of (Chinese) rhubarb. Two new stilbene glycosides, 4'-O- methylpiceid and rhapontin, isolated from the roots, exhibited moderate alpha-glucosidase inhibitory activity. Anthraquinone glucoside, pul- matin, isolated from the roots, along with its congeners, chrysophanein and physcionin, showed cytotoxic activity against several types of carcinoma cells. Polysaccharides, isolated from the roots and rhizomes, contained lyx- ose, glucose, galactose, xylose, rham- nose, mannose and ribose.

Broadly, having dull aching in joints, muscles, eyes, and so forth. In a more literal sense, it is having an autoimmune response, usually between certain IgM and IgE antibodies, that may have started as a bacterial infection or as some autoimmune reaction. The severity is increased under emotional, physical, dietary, and allergic stressor any stress. Hans Selye showed a few years ago that once a chronic disease response occurs, any stress above metabolic tolerance will aggravate the chronic disease, which is why some people, stressed by cold, wet weather, must avoid it; but someone else is stressed by legumes, still another person gets upset (and stressed) by watching too much CNN. You know best what stresses you; it’s not fair to ask a doc to find it out for you.

The bones, 12 on each side, which enclose the cavity of the chest. The upper seven are joined to the breast-bone by their costal cartilages and are therefore known as true ribs. The lower ?ve do not reach the breast-bone, and are therefore known as false ribs. Of the latter, the eighth, ninth and tenth are joined by their costal cartilages, each one to the rib immediately above it, while the 11th and 12th are free from any such connection and are therefore known as ?oating ribs. Each rib has a head, by which it is joined to the upper part of the body of the vertebra with which it corresponds, as well as to the vertebra immediately above. The greater part of the bone is made up of the shaft, which runs at ?rst outwards and at the angle turns sharply forwards. On the lower margin of the shaft is a groove, which lodges the corresponding intercostal artery and nerve.... ribs

Siddha/Tamil: Ammanakku.
Action: Oil from seeds and young leaf—purgative. Oil is used in dermatosis and eczema. Leaves— used as poultice to extract the worm.
Root—a decoction is administered for lumbago and allied complaints.Bark—purgative.The Ayurvedic Pharmacopoeia ofIn- dia recommends the decoction of the dried, mature root in rheumatism, pain in the urinary bladder, lumbago, diseases of the abdomen and inflammations; fresh leaf in helminthiasis, dysu- ria, arthritis, pain in the urinary bladder, dysuria, abscesses; dried seed powder in constipation, rheumatism, diseases of the liver and spleen, piles, lumbago, sciatica.The root extract exhibited significant anti-inflammatory activity against carrageenan-, bradykinin-, 5-HT-and dextran-induced rat hind paw oedema. N-Demethylricinine showed dose-dependent anticholestatic and hepato- protective activities in rats.Castor oil, derived from the seeds, is a well-known purgative (dose 520 ml).Castor seed contains toxic components (2.8-3.0% on whole seed; about 10% in the flour) which are highly poisonous to human beings and animals. The principal toxic substance is the albumin, ricin. Allergens and a feebly toxic alkaloid ricinine is also present. An ulcerative factor in the seed is reported. Like other toxalbumins, ricin agglutinizes the mammalian red bleed corpuscles. (Ricin loses its toxicity and antigenic action on treatment with potassium permanganate.)Castor oil consists principally of ri- cinoleic acid. Stearic, oleic, linoleic and dihydroxystearic acids are present in small amounts. The strong laxative property of castor oil is reported due to the local irritant action caused in the intestines by ricinoleic acid formed by hydrolysis under the influence of lipolytic enzymes. (The oil should not be used with fat-soluble vermifuge, it may increase its absorption and toxic- ity.)
Dosage: Root—20-30 g for decoction. (API, Vol. I.) Leaf—10- 20 ml juice; 2-5 g powder; seed— 0.5-3 g powder. (API, Vol. III.)... ricinus communis

Key application: Leaf—internally in dyspeptic complaints; externally in supportive therapy for rheumatic diseases and circulatory problems. (German Commission E.) Shows improvement of hepatic and biliary function.(ESCOP.) Carminative, spasmolytic of hepatic and biliary function. (ESCOP.) Carminative, spasmolytic. (The British Herbal Pharmacopoeia.)In research using rats, the essential oil and ethanolic extract of rosemary decreased drug-induced hepatotoxici- ty and the suppression of bone marrow cells. Phenolic compounds in the herb exhibit antioxidant activity. (Sharon M. Herr.)The herb contains volatile oil (1.02.5%), composed mainly of 1, 8-cineole (20-25%), alpha-pinene (15-25%), camphor (10-25%), others include bor- neol, isobutyl acetate, camphene, li- monene, linalool, 3-octanone, terpine- ol, verbenol; flavonoids including api- genin, diosmetin, diosmin; rosmarinic acid and other phenolic acids; diter- penes; rosmaricine; ursolic acid, olea- nolic acid and their derivatives.The anti-inflammatory effect of Rosemary has been attributed to ros- marinic acid, ursolic acid and apigenin. Among flavonoids, diosmin is reported to be more effective in decreasing capillary fragility than rutin. A ros- maricine derivative exhibits stimulant and mild analgesic activity.The phenolic fraction, isolated from the leaves, also from the oil, exhibits antioxidant activity.Pressed juice of leaves possesses a strong antibacterial action on Staphylococcus aureus, E. coli and Bacillis sub- tilis.An infusion of the plant with borax is used as a hair wash for preventing hair loss.Rosemary oil, in combination with the essential oil from thyme, lavender and cedarwood, showed improvement in hair growth by 44% after 7 months of treatment for alopecia areata.

Having a lucid dream means dreaming while being aware of the fact that you are dreaming.
However, many people become lucid in the middle of the dream or, on the contrary, fall lose reality contact after being lucid at first.
Although traditional medicine can’t be very helpful in these cases, alternative medicine has a few tricks up its sleeve.
How a Tea for Lucid Dreams Works
A Tea for Lucid Dreams’ main purpose is to make you recall what you have dreamed by calming your nervous system and improving your memory function.
These teas are good for a number of other diseases, such as memory loss, headaches or migraines. However, talk to an herbalist or to your doctor before starting any kind of herbal treatment in order to make sure everything will be alright.
Efficient Tea for Lucid Dreams
In order to work properly, a Tea for Lucid Dreams needs to be both very efficient and one hundred percent safe (since lucid dreams are not exactly a medical problem, you may want to avoid developing one).
A tea that is rich in antioxidants, nutrients, tannins, volatile oils and minerals (sodium, magnesium, iron, manganese) would be very adequate.
You may want to avoid teas with a large amount of acid agents (they could cause stomach pain). If you don’t know which teas could be useful for lucid dreams, here’s a list for guidance:
- Green Tea – contains all the ingredients necessary to sustain life, so it’s useful for a wide range of ailments, not just lucid dreams. If you’re suffering from infertility, anemia, asthenia, loss of appetite, digestive tract complaints or nervous system failure, this decoction could also be useful.
However, you must avoid it at all costs if you’re experiencing some menstrual or menopausal symptoms. The same advice if you’re pregnant (it may cause uterine contractions and therefore miscarriage).
- Valerian Tea – was been used as a sleep aid since ancient times, when the Romans and the Greeks took it before going to bed. This Tea for Lucid Dreams, thanks to its active compounds, is a mild sedative and could also work miracles on your nervous system.
However, you need to make sure that you don’t exceed the number of cups recommended per day in order to avoid hallucinations, tiredness or even death.
- Chamomile Tea – of course, the world’s greatest panacea shouldn’t be left aside. If you’re having trouble remembering your dreams, try a cup of Chamomile Tea before you go to bed! This Tea has a great fragrance and a pleasant smell. Plus, it’s one hundred percent safe so you can drink as much as you want.
Tea for Lucid Dreams Side Effects
When taken according to specifications, these teas are generally safe. However, exceeding the number of cups recommended per day may lead to a number of health problems, such as diarrhea, nausea, vomiting, upset stomach or even death!
If you’ve been taking one of these decoctions for a while and you’re experience a negative response from your body, ask for medical assistance right away!
Don’t take a Tea for Lucid Dreams if you’re pregnant, breastfeeding, on blood thinners or anticoagulants. The same advice in case you’re preparing for a surgery.

A term used to describe periods spent in bed. Bed rest may be a part of treatment in certain illnesses, such as rheumatic fever, and for some types of injury, such as a fractured vertebra. Prolonged bed rest carries risks such as muscle wasting, weakness, and increased risk of blood clots developing in the legs. Bed rest was once considered an essential part of the treatment of many common conditions but is now avoided whenever possible. Patients are now encouraged to be mobile as soon as possible after surgery.... bed rest

Oedema. Hydrops. Not a disease but a condition. An abnormal accumulation of fluid in a body cavity or beneath the skin. Due to weakened walls of capillaries caused by circulating toxins obstructing the flow of blood or lymph. Gross oedema of nephrotic syndrome associated with low plasma protein level and high proteinuria.
Renal dropsy is worse in the early morning, with loose tissues under the eyes.
Treatment. When fluid rapidly collects it may have to be aspirated (drawn off) but before this stage is reached herbal diuretics and cardiac tonics have much to offer. In acute conditions, sweat glands should be stimulated by suitable diaphoretics to assist elimination of excess fluid through the skin. Attention to the bowels is important; a timely copious bowel action greatly assisting elimination. A well-known diuretic for dropsy is Juniper, 3 to 5 drops taken in honey 2 or 3 times daily.

a quickly performed test to assess the adequacy of circulation in an individual with poor cardiac output. An area of skin is pressed firmly by (say) a fingertip until it loses its colour; the number of seconds for the area to return to its original colour indicates capillary refill time. Normal capillary refill takes around 2 seconds. Slow capillary refill may occur globally in an individual with poor circulation or in a small area (e.g. a toe) in which local circulation is compromised (due, for example, to peripheral vascular disease). This test may not be very useful in people with dark skin.... capillary refill time

(CROS hearing aid) a form of hearing aid used to help people with severe or profound unilateral hearing loss. Sound information is collected by a microphone worn on the affected side and then transmitted by a thin wire or Bluetooth wireless technology to a device worn on the opposite side. If the hearing in the better ear is normal, no amplification is applied to the signal. If the better ear has a hearing loss the device also acts as a conventional hearing aid and amplifies the signal from both sides: this is known as a BICROS hearing aid.... contralateral-routing-of-signal hearing aid
(CRPS, reflex sympathetic dystrophy, RSD, Sudek’s atrophy) neurological dysfunction in a limb following trauma, surgery, or disease, characterized by intense burning pain, swelling, stiffness, and sweaty shiny mottled skin. It is caused by overactivity of the sympathetic nervous system. The *ESR is often elevated, X-rays may reveal some patchy osteoporosis, and a bone scan usually demonstrates increased blood flow. Early treatment with splinting and physiotherapy are essential, in combination with *sympatholytic drugs, corticosteroids, and regional sympathetic blocks; *sympathectomy may be required in chronic cases.... complex regional pain syndrome
(fusion imaging) n. (in diagnostic imaging) the process of taking two images obtained by different techniques and (usually electronically) laying them on top of each other after suitable adjustment, so that the anatomical landmarks coincide. This can give more accurate information as one technique shows the anatomy and the other shows the pathology. Co-registering can thus show which part of the body is involved in the disease process. It is typically used in *PET/CT scanning. CT or MRI scans can also be fused onto real time ultrasound images to target a lesion for biopsy or treatment.... co-registration

It can be administered intravenously as part of the CRH test, during which blood is analysed at 15-minute intervals for one hour for the ACTH response, which is excessive in cases of primary adrenal failure and suppressed in cases of anterior *hypopituitarism.... corticotrophin-releasing hormone
a superficial reflex in males elicited by stroking the inner side of the upper thigh with a sharp object. If the reflex is intact the scrotum on that side is pulled upwards as the cremaster muscle contracts. Absence or reduction of both cremasteric reflexes indicates an upper *motor neuron lesion; absence of the reflex on one side suggests a lower motor neuron lesion at the level of the first lumbar spinal nerve.... cremasteric reflex

(CRL) the longest measurement of the fetus from end to end. Measurement of the CRL of the embryo in the first trimester has been shown to be the most accurate parameter for assessment of gestational age; the measurement is less accurate at the end of the first trimester because of fetal flexion.... crown–rump length
the total number of events (e.g. cases of lung cancer) expressed as a rate per 1000 population. When factors such as age structure or sex of populations can significantly affect the rates (as in *mortality or *morbidity rates) it is more meaningful to compare age/sex specific rates using one or more age groups of a designated sex (e.g. lung cancer in males aged 55–64 years). More complex calculations, which take account of the age and sex structure of a population as a whole, can produce *standardized rates and *standardized mortality ratios (SMR).... crude rate
see prostatectomy.... da vinci robot
a *delusion in which the patient believes that unsuspicious occurrences refer to him or her in person. Patients may, for example, believe that certain news bulletins have a direct reference to them, that music played on the radio is played for them, or that car licence plates have a meaning relevant to them. Ideas of reference differ from delusions of reference in that insight is retained.... delusion of reference
see retinopathy.... diabetic retinopathy
(DR) an alternative to film radiography, by acquiring X-ray images from a large number of individual X-ray detectors on a matrix in a digital format directly. This contrasts with *computerized radiography, in which an *analogue image is taken and then put into a reader to be converted into a *digital image. The technique allows the storage of images and their subsequent retrieval, manipulation, and interpretation using computers (see PACS).... digital radiography

a variety of mechanisms that help to ensure that the genetic sequence, as expressed in the DNA, is maintained and that errors that occur during DNA replication, by mutation, are not allowed to accumulate. An error in the genetic sequence could cause cell death by interfering with the replication process. DNA repair involves the action of enzymes, which detect damage to DNA and effect the repair. Some genetic diseases, including *ataxia telangiectasia and *xeroderma pigmentosum, are due to deficiencies in these enzymes.... dna repair
see DNAR order.... do not attempt resuscitation order
(Eisenmenger syndrome) a condition in which *pulmonary hypertension is associated with a *septal defect, so that blood flows from the right to the left side of the heart or from the pulmonary artery to the aorta. This allows blue blood, poor in oxygen, to bypass the lungs and enter the general circulation. This reduces the oxygen content of the arterial blood in the aorta and its branches, resulting in a patient with a dusky blue appearance (*cyanosis) and an increased number of red blood cells (*polycythaemia). There is no curative treatment at this stage, but the patient may be helped by the control of heart failure and polycythaemia. The condition may be prevented by appropriate treatment of the septal defect in early childhood before irreversible pulmonary hypertension develops. [V. Eisenmenger (1864–1932), German physician]... eisenmenger reaction
(ER) a system of membranes present in the cytoplasm of cells. ER is described as rough when it has *ribosomes attached to its surface and smooth when ribosomes are absent.

a group of drugs used in the treatment of type 2 diabetes. They mimic the actions of *glucagon-like peptide-1 in regulating the rise in blood glucose levels after eating and they also enhance satiety (see incretin). As these drugs respond to a falling blood glucose level there is a reduced tendency to *hypoglycaemia compared with *sulphonylurea drugs and insulin therapy itself. They are given by subcutaneous injection and three of them are licensed for use in the UK: exenatide (Byetta; twice daily dosing), liraglutide (Victoza; once daily dosing), and lixisenatide (Lyxumia; once daily dosing).... glp-1 receptor agonists
(GnRH, gonadorelin) a peptide hormone produced in the hypothalamus and transported via the bloodstream to the pituitary gland, where it controls the synthesis and release of pituitary *gonadotrophins.

(ILR) a device, inserted beneath the skin of the chest, to record the heart rhythm for up to two years. It is usually used for the investigation of patients presenting with infrequent syncope (fainting) in whom arrhythmia is the suspected cause. When syncope occurs, the device can be examined using wireless technology to reveal the heart rhythm at the time of the episode.... implantable loop recorder
(IMR) the number of deaths of children under one year of age per 1000 live births in a given year. Included in the IMR are the neonatal mortality rate (calculated from deaths occurring in the first four weeks of life) and postneonatal mortality rate (from deaths occurring from four weeks). Neonatal deaths are further subdivided into early (first week) and late (second, third, and fourth weeks). In prosperous countries neonatal deaths account for about two-thirds of infant mortalities, the majority being in the first week (in the UK the major cause is prematurity and related problems). The IMR is usually regarded more as a measure of social affluence than a measure of the quality of antenatal and/or obstetric care; the latter is more truly reflected in the *perinatal mortality rate.... infant mortality rate
diminution in the response of the body’s tissues to insulin, so that higher concentrations of serum insulin are required to maintain normal circulating glucose levels. Eventually the islet cells can no longer produce adequate amounts of insulin for effective glucose lowering, resulting in hyperglycaemia. Insulin resistance is one of the risk factors for cardiovascular disease. See also diabetes mellitus; metabolic syndrome.... insulin resistance
(IMRT) radiotherapy using multiple beams with variable intensity across each field, resulting in dose distributions that can fit to concave shapes and thus reduce dose to surrounding healthy tissues and organs. It can be used to treat a wide range of cancers and can enable safe delivery of higher doses to tumours.... intensity-modulated radiotherapy
see INR.... international normalized ratio
a branch of radiology in which complex procedures are performed using imaging guidance, which avoids patients having to undergo invasive surgery to achieve the same results. This is often termed ‘pinhole surgery’. Guidance is commonly by X-ray fluoroscopy, ultrasound, or computerized tomography, and recently also by magnetic resonance imaging. Procedures commonly performed include angioplasty and stenting of vascular structures, drainage of fluid collections or abscesses, stenting of obstructions to the gastrointestinal tract, embolization, cryotherapy, and radiofrequency ablation.... interventional radiology
(IUGR, fetal growth restriction) failure of a fetus to achieve its growth potential, resulting in the birth of a baby whose birth weight is abnormally low in relation to its gestational age (see small for gestational age). Causes include *uteroplacental insufficiency, maternal disease (e.g. infection, malnutrition, high blood pressure, smoking, and alcoholism), poor socioeconomic conditions, multiple pregnancy (e.g. twins), and fetal disease or chromosomal abnormalities. It may be associated with *preterm birth.... intrauterine growth restriction
(Herxheimer reaction) exacerbation of the symptoms of syphilis that may occur on starting antibiotic therapy for the disease. The effect is transient and requires no treatment. [A.

the number of deaths due to complications of pregnancy, childbirth, and the puerperium per 100,000 live births (see also stillbirth). In 1952 concern about maternal mortality resulted in Britain in the setting up of a triennial *confidential enquiry into every such death to identify any shortfall in resources or care. The first triennial report was published in 1985. Since 2014 reports have been produced annually by MBRRACE-UK (Mothers and Babies: Reducing Risk through Audits and Confidential Enquiries Across the UK). Levels of *maternal deaths are currently low: a report published in 2017 (covering 2013–15) counted 202 obstetric-related deaths (8.76 per 100,000 live births). Thromboembolism was the commonest direct cause of death (30 deaths, 1.13 per 100,000 live births), while heart disease was the commonest indirect cause of death (54 deaths, 2.34 per 100,000 live births).... maternal mortality rate
(Rokitansky–Küster–Hauser syndrome, Müllerian agenesis) congenital absence of the uterus and upper part of the vagina due to failure of development of the *Müllerian duct. It may be associated with skeletal, renal, and auditory abnormalities, but usually presents with amenorrhoea in a patient with otherwise normal secondary sexual characteristics. There is a multidisciplinary approach to treatment, with psychological support, counselling, discussion of creation of a ‘neovagina’ with gradual use of vaginal dilators, and/or surgical vaginal reconstruction. Surrogacy is the only option for childbearing, although oocyte donation from the mother to a surrogate can be discussed. [K. W. Mayer (1795–1868), German gynaecologist; K. von Rokitansky (1804–78), Austrian pathologist; H. Küster and G. A.

(MHRT) a tribunal, established under the Mental Health Act 1959 and now operating under the Mental Health Act 2007, to which applications may be made for the discharge from hospital of a person compulsorily detained there under provisions of the Act (see compulsory admission). When a patient is subject to a restriction order an application may only be made after his or her first six months of detention. The powers of the tribunal, which comprises both legally and medically qualified members, include reclassifying unrestricted patients, recommending leave of absence for a patient, delaying discharge, and transferring patients to other hospitals. Detained patients may also apply to have a managers hearing to review their detention. The powers of the managers hearing are slightly different from those of the MHRT, but both are defined in the Mental Health Act 2007 and both can discharge a patient from a section of the Mental Health Act.... mental health review tribunal
a laboratory measurement used as a screening test for the first signs of kidney damage in *diabetes mellitus.

(MERS) a viral respiratory infection that was first identified in 2012. Humans seem to be infected most easily by contact with dromedary camels (hence the informal name camel flu), although human-to-human infection also occurs. Symptoms include fever, cough, and shortness of breath. Although the syndrome is often mild, death occurs in about a third of diagnosed cases. Most reported cases have been in the Arabian Peninsula, although there was a major outbreak in South Korea in 2015. At present there is no vaccine or treatment.... middle east respiratory syndrome

(mitral incompetence) failure of the *mitral valve to close, allowing a reflux of blood from the left ventricle of the heart to the left atrium. It may be due to mitral valve prolapse (MVP) in which one or both valve leaflets flop back into the left atrium (also known as ‘floppy mitral valve’). It also results from chronic rheumatic scarring of the valve, or is secondary to left ventricular muscle damage. Its manifestations include breathlessness, atrial *fibrillation, embolism, enlargement of the left ventricle, and a systolic *murmur. Mild cases are symptomless and require no treatment, but in severe cases the affected valve should be repaired or replaced with an artificial one (mitral prosthesis).... mitral regurgitation

(startle reflex) a primitive reflex seen in newborn babies in response to the stimulus of a sudden noise or movement: the baby will fling its arms and legs wide and will appear to stiffen; the arms and legs are then drawn back into flexion. The Moro reflex should disappear spontaneously by four months. Its presence beyond this age is suggestive of an underlying neurological disorder, such as cerebral palsy. [E. Moro (1874–1951), German paediatrician]... moro reflex
(MPR) a computer technique that allows images to be created, after the information has been collected (see post-processing), in any of the three named planes – *axial, *sagittal, or *coronal – or variations of these, such as oblique or curved planes.

acute kidney injury caused by myoglobin that is released from damaged skeletal muscle (*rhabdomyolysis). This is usually the result of trauma and the condition was first recognized in victims trapped and crushed during the London Blitz. Muscle injury can also occur with pressure necrosis, particularly in the unconscious or immobile patient, or with a *compartment syndrome. Rarely it may complicate intensive muscular exercise or extensive viral myositis and it is a recognized complication of modest overexertion in some inherited disorders of muscle metabolism, such as *McArdle’s disease.... myoglobinuric acute renal failure
an agent that reduces tension in voluntary muscles. Drugs such as *baclofen, *dantrolene, and *diazepam are used to relieve skeletal muscular spasms in various spastic conditions, parkinsonism, and tetanus. The drugs used to relax voluntary muscles during the administration of anaesthetics in surgical operations act by blocking the transmission of impulses at neuromuscular junctions. Nondepolarizing muscle relaxants, e.g. *atracurium besilate, cisatracurium, pancuronium, and rocuronium, bind to receptor sites normally occupied by acetylcholine; depolarizing muscle relaxants, e.g. *suxamethonium, mimic the action of acetylcholine but *depolarization is prolonged.... muscle relaxant

(hereditary haemorrhagic telangiectasia) a hereditary (autosomal *dominant) disorder characterized by thinning of the blood vessel walls, resulting in abnormally wide and fragile blood vessels. Patients may develop telangiectasia (see telangiectasis), nosebleeds, and arteriovenous malformations (see angioma). It is caused by mutations in the endoglin (ENG) gene or the activin receptor-like kinase (ALK-1) gene. [Sir W. Osler (1849–1919), Canadian physician; H. J. M. Rendu (1844–1902), French physician; F. P. Weber (1863–1962), British physician]... osler–rendu–weber disease
(PERT) a therapeutic approach using supplements of the digestive enzymes lipase, amylase, and protease (Creon, Pancrex), which are given when there is insufficient endogenous production of pancreatic enzymes: for example, to patients with pancreatic cancer or cystic fibrosis. The capsules must be taken with all meals and snacks to be effective. PERT treats the symptoms of *steatorrhoea.... pancreatic enzyme replacement therapy
(PTH-RP) a protein that is secreted by certain malignant tumours and is the main cause of malignant *hypercalcaemia. PTH-RP, which has effects similar to *parathyroid hormone, stimulates generalized bone resorption and excessive calcium reabsorption in the kidney tubules. It is most commonly produced by lung tumours, squamous-cell carcinomas of other organs, melanomas, and tumours of the breast, liver, pancreas, bladder, and prostate.... parathyroid hormone-related protein

(knee jerk) reflex contraction of the quadriceps (thigh) muscle so that the leg kicks, elicited in a patient sitting with one knee crossed over the other by sharply tapping the tendon of the muscle below the kneecap. The reflex is mediated through nerves emanating from the third and fourth lumbar spinal levels (see spinal nerves). This is a test of the connection between the sensory nerves attached to stretch receptors in the muscle, the spinal cord, and the motor neurons running from the cord to the thigh muscle, all of which are involved in the reflex. The patellar reflex is reduced or absent when there is disease or damage of the spinal cord at or below the level of the reflex and exaggerated in disorders above the level of the reflex.... patellar reflex
(PEFR) the maximum rate at which a person can forcibly expel air from the lungs at any time, expressed usually in litres per minute (occasionally in litres per second). A low value can help diagnose asthma in the correct clinical context, and differences between the morning and evening values can also be a feature of poor control of asthma. There is a place for PEFR in the monitoring of acute exacerbations of chronic pulmonary obstructive disease (COPD) but not in the diagnosis of COPD.... peak expiratory flow rate
(PRRT) a type of radiotherapy used to treat neuroendocrine tumours (NETs; see neuroendocrine system). A *radionuclide is combined with a relevant *peptide to create a so-called radiopeptide, which is injected into the patient’s bloodstream. Because NETs have an overexpression of peptide receptors, the radiopeptide binds to the tumour, delivering a high dose of radiation directly to the cancer cells. The chief merit of PRRT is this ability to target delivery of radionuclides for highly localized treatment. A similar technique, using a gamma emitter as the radionuclide, can be used for locating and imaging NETs.... peptide receptor radionuclide therapy

the administration of an estimated amount of the radioactive isotope iodine-131 as a drink in order to treat an overactive thyroid gland (see thyrotoxicosis). The iodine concentrates in the thyroid and thus delivers its beta radiation locally, with little effect on other tissues. The gland will shrink and become euthyroid over the succeeding 8–12 weeks but there is a high incidence of subsequent hypothyroidism (up to 80%), which requires lifetime treatment with thyroxine. The treatment cannot be used if there is any suspicion of pregnancy, and the patient must stay away from young children and pregnant women for around 10 days after administration. Despite these drawbacks, radioactive iodine remains a popular form of treatment for any cause of hyperthyroidism.... radioactive iodine therapy
(RPM) see palatoplasty.... radiofrequency palatal myoplasty

n. an instrument used in *endodontics to clean, cut, and prepare the walls of a root canal for *root canal treatment.... reamer
a condition of postprandial *hypoglycaemia, of varying severity, induced by excessive levels of insulin release from the pancreas. It can be divided into early and late forms, depending on whether the insulin release occurs less than or more than three hours after the meal. The early form is due to the rapid discharge of ingested carbohydrate from the stomach into the small bowel, immediately triggering hyperinsulinaemia. It can occur without obvious cause but is most commonly associated with upper-bowel surgery. The late form is due to a loss of the early-phase insulin response causing excessive postprandial *hyperglycaemia, which then itself triggers an exaggerated insulin response with subsequent hypoglycaemia.... reactive hypoglycaemia
the rapid acquisition and manipulation of ultrasound information from a scanning probe by electronic circuits to enable images to be produced on TV screens almost instantaneously. The operator can place the scanning probe accurately on the region of interest in order to observe its structure and appreciate moving structures within it (see Doppler ultrasound). Using similar techniques, the instantaneous display of other imaging modalities, such as *computerized tomography scanning and *magnetic resonance imaging, can now be achieved. Real-time imaging is useful in guiding *interventional radiology procedures, for example, allowing a needle to be guided accurately as it is passed into the body. It is also useful for observing dynamic physiological activity.... real-time imaging

In the acute phase steroid administration may help, but in established RPF *ureterolysis is required.... retroperitoneal fibrosis
a depression in the uterine wall marking the junction between the actively contracting muscle fibres of the upper segment of the uterus and the muscle fibres of the lower segment. This depression is not always visible and is normal. In obstructed labour (e.g. contracted pelvis or malposition of the fetus resulting in shoulder presentation), the muscle fibres of the upper segment become shorter and thicker; the muscle fibres of the lower segment, on the other hand, become elongated and thinner. The junction between the two becomes more distinct as it rises into the abdomen from the pelvis. This abnormal ring is known as Bandl’s ring and is a sign of impending rupture of the lower segment of the uterus, which becomes progressively thinner as Bandl’s ring rises upwards. Immediate action to relieve the obstruction is then necessary, usually in the form of Caesarean section.... retraction ring

OTHER SPECIES: There are a great many varieties of chamomile found throughout the world, four of which are native to the British Isles, but the only one of these used therapeutically is the Roman chamomile (C. nobile).
HERBAL/FOLK TRADITION: This herb has had a medical reputation in Europe and especially in the Mediterranean region for over 2000 years, and it is still in widespread use. It was employed by the ancient Egyptians and the Moors, and it was one of the Saxons’ nine sacred herbs, which they called ‘maythen’. It was also held to be the ‘plant’s physician’, since it promoted the health of plants nearby.
It is current in the British Herbal Pharmacopoeia for the treatment of dyspepsia, nausea, anorexia, vomiting in pregnancy, dysmenorrhoea and specifically flatulent dyspepsia associated with mental stress.
ACTIONS: Analgesic, anti-anaemic, antineuralgic, antiphlogistic, antiseptic, antispasmodic, bactericidal, carminative, cholagogue, cicatrisant, digestive, emmenagogue, febrifuge, hepatic, hypnotic, nerve sedative, stomachic, sudorific, tonic, vermifuge, vulnerary.
EXTRACTION: Essential oil by steam distillation of the flower heads.
CHARACTERISTICS: A pale blue liquid (turning yellow on keeping) with a warm, sweet, fruity-herbaceous scent. It blends well with bergamot, clary sage, oakmoss, jasmine, labdanum, neroli, rose, geranium and lavender.
PRINCIPAL CONSTITUENTS: Mainly esters of angelic and tiglic acids (approx. 85 per cent), with pinene, farnesol, nerolidol, chamazulene, pinocarvone, cineol, among others.
SAFETY DATA: Non-toxic, non-irritant; can cause dermatitis in some individuals.

Rosa damascena
FAMILY: Rosaceae
SYNONYMS: Summer damask rose, Bulgarian rose, Turkish rose (Anatolian rose oil), otto of rose (oil), attar of rose (oil).
GENERAL DESCRIPTION: Small prickly shrub between 1 metre and 2 metres high, with pink, very fragrant blooms with thirty-six petals, and whitish hairy leaves. It requires a very specific soil and climate.
DISTRIBUTION: Believed to be a native of the Orient, now cultivated mainly in Bulgaria, Turkey and France. Similar types are grown in China, India and Russia; however, India produces only rose water and aytar – a mixture of rose otto and sandalwood.
OTHER SPECIES: There are many different subspecies: the Turkish variety is known simply as R. damascena. ‘Trigintipetala’ is the principal cultivar in commercial cultivation, known as the ‘Kazanlik rose’. Bulgaria also grows the white rose (R. damascena var. alba) or the musk rose (R. muscatta) which is used as a windbreak around the damask rose plantations. See also cabbage rose and the Botanical Classification section.
HERBAL/FOLK TRADITION: ‘The damask rose, on account of its fragrance, belongs to the cephalics; but the next valuable virtue that it possesses consists in its cathartic quality ... oil of roses is used by itself to cool hot inflammations or swellings, and to bind and stay fluxes of humours to sores.’.
Rose hips are still current in the British Herbal Pharmacopoeia, mainly due to their high vitamin C content (also A and B). For further general properties, see entry for cabbage rose.
ACTIONS: See cabbage rose.
EXTRACTION: 1. Essential oil or otto by water or steam distillation from the fresh petals. 2. A concrete and absolute by solvent extraction from the fresh petals.
CHARACTERISTICS: 1. A pale yellow or olive yellow liquid with a very rich, deep, sweet-floral, slightly spicy scent. 2. The absolute is a reddishorange or olive viscous liquid with a rich, sweet, spicy-floral, tenacious odour. It blends well with most oils, and is useful for ‘rounding off’ blends. The Bulgarian type is considered superior in perfumery work, but in therapeutic practice it is more a matter of differing properties between the various types of rose.
PRINCIPAL CONSTITUENTS: Mainly citronellal (34–55 per cent), geraniol and nerol (30–40 per cent), stearopten (16–22 per cent), phenyl ethanol (1.5–3 per cent) and farnesol (0.2–2 per cent), with many other trace constituents.
SAFETY DATA: Non-toxic, non-irritant, nonsensitizing.

Ravensara aromatica
FAMILY: Lauraceae
SYNONYMS: Madagascar clove-nutmeg, aromatic ravensare, Ravensara anisata, Agatophyllum aromaticum.
GENERAL DESCRIPTION: The genus Ravensara includes many species of evergreen trees or shrubs native to Madagascar and the Comoro Islands. These evergreen trees can grow up to 30 metres tall in rainforests, usually on all type of soils. The best-known species of this genus is R. aromatica used for its essential oil. It grows to a height of about 20 metres with several buttress roots at the base, with reddish bark, dark green shiny leaves and small yellow-green flowers. The fruit, a fleshy berry, are an important food source for birds. All parts of the tree are aromatic.
DISTRIBUTION: R. aromatica is native to Madagascar and once thrived in the rainforests, but is now an endangered species due to de-forestation and over-exploitation. By the early part of this century, this species required protection as the production of the essential oil from the bark, used by the pharmaceutical industry, was particularly destructive as it required felling the trees. Only the leaves can now be used for oil production, to prevent cutting down the whole tree. There is now a conservation programme in place to protect these trees: it is therefore important to obtain the essential oil of the leaf from sustainable sources.
OTHER SPECIES: There are over 30 species of Ravensara that grow in Madagascar. The common name of the genus Ravensara is actually a latinization of the Malagasy term ravintsara which means ‘good leaves’, a term originally used by the natives to describe another species of tree. European botanists in the nineteenth century made several attempts to classify the various indigenous aromatic trees of Madagascar, but due to the similarity of the two names ‘ravintsara’ and ‘ravensara’ they came to be used almost interchangeably. The botanical confusion between these two species has continued to cause a great deal of uncertainty as to their precise origins. In fact, the essential oils derived from these two species are very different aromatically as well as in their chemical composition. However, most of so-called ‘ravensara’ oil from Madagascar, is actually produced from the Cinnamomum camphora species (even if it is said to derive from R. aromatica) so great care needs to be taken in identifying the correct source of each oil. See also entry for Ravintsara.
HERBAL/FOLK TRADITION: In Madagascar, this genus of trees is commonly called hazomanitra, meaning ‘tree that smells’, as the whole part of the plant is aromatic. Traditionally, the Malagasy people used the bark and stem as a tonic and as an antibacterial medicine. The leaves were also burnt in homes after a death to prevent the spread of disease while the anise-flavoured bark was used in the production of local rum. The oil from the Ravensara genus is referred to locally as ‘the oil that heals’ because it is used for so many different conditions. The essential oil from the bark, R. anisata (a synonym for R. aromatica) is known as ‘havozo’ and has a strong anise-like odour.
ACTIONS: Antiviral, antibacterial, antifungal, anti-infectious, antiseptic, antispasmodic, expectorant, immune-stimulant.
EXTRACTION: 1. Ravensara oil is steam distilled from the leaves of the plant. 2. The essential oil distilled from the bark is called havozo. 3. An essential oil is also extracted occasionally from the fleshy fruits or berries.
CHARACTERISTICS: 1. Ravensara oil (from the leaf) has a sweet, fresh, slightly lemony, licorice-like scent with an earthy undertone. 2. Havozo (from the bark) has a fresh, strong aniseed-like odour.
PRINCIPAL CONSTITUENTS: 1. The oil from the leaf contains relatively small amounts of methyl chavicol (estragole), myrcene, a-pinene and linalool with the main constituents being limonene (approx. 13–22 per cent) and sabinene (approx. 10–16 per cent) with very little 1,8-cineole (1.8–3.3 per cent). 2. Havozo (bark oil) has a high methyl chavicol content (up to 90 per cent).
SAFETY DATA: 1. Ravensara (R. aromatica) is generally considered a safe oil (non-toxic and non-irritant) although it is best avoided during pregnancy. 2. Havozo oil is not recommended for use in aromatherapy due to its high methyl chavicol content, as it is a suspected carcinogen. Research has shown, nevertheless this oil has potent anti-microbial properties, being active against E. coli.

Cinnamomum camphora
FAMILY: Lauraceae
SYNONYMS: Cinnamomum camphora ct. 1,8-cineole.
GENERAL DESCRIPTION: Cinnamomum camphora is a tall evergreen tropical tree characteristic of the Laurel family that grows up to 20–30 metres tall. The foliage is bright green and the leaves have a glossy, waxy appearance bearing masses of small white flowers in spring. It produces clusters of shiny black berries and has a pale bark that is very rough and fissured vertically.
DISTRIBUTION: C. camphora is native to China, Japan, and Taiwan but has been introduced to many countries throughout the world including India, Australia and the USA, where in places such as Florida it is becoming increasingly invasive and a danger to the native flora. This species is not indigenous to Madagascar and was introduced onto the island during the middle of the nineteenth century. As the plant became accustomed to the Malagasy climate it became a distinct subspecies, which in time adapted so well to the new environment, naturalizing in the central-eastern regions, that it became a very sustainable species for producing an essential oil, now called ravintsara oil. However, since it is clear there are many different sub-varieties of C. camphora in various parts of the world, it is possible that there also existed another native aromatic tree already growing in Madagascar originally known as ravintsara by the local people. According to Georges M. Halpern in The Healing Trail: Essential Oils of Madagascar, an indigenous tree of this name had been part of the Malagasy culture for many centuries and its leaves were used as a traditional folk medicine.
OTHER SPECIES: The genus Cinnamomum has approximately 250 different species, many of which yield an essential oil on distillation. Amongst the most important are C. zeylanicum (cinnamon bark and leaf oils) and C. cassia (cassia oil). The single species C. camphora itself produces a wide range of essential oils including: camphor, ho wood and leaf oil, sassafras and ravintsara. All these essential oils, although derived from the same tropical tree or botanical species, differ in their chemical profile enormously depending on the country of origin as well as the part of the plant used to extract the oil: e.g. leaf or bark.
There are at least 6 different chemotypes of C. camphora essential oil due to this factor, including the camphor, linalool, 1,8-cineole, nerolidol, safrole and borneol types. For example, C. camphora, grown in Taiwan and Japan, is known as Ho oil, and has linalool as its major constituent, whereas in India and Sri Lanka the camphor type of C. camphora remains the most important. The variety of C. camphora cultivated in Madagascar contains high levels of 1,8-cineole and no camphor. In order to avoid any confusion, it has been suggested that Ravintsara should be labelled: ‘Cinnamomum camphora ct. 1,8-cineole.’
HERBAL/FOLK TRADITION: The term Cinnamomum is derived from the Greek root kinnamon or kinnamomon meaning ‘sweet wood’. The word ravint means leaf and sara means ‘good for you’ according to the Malagasy tradition, as the local people have long appreciated the therapeutic value of its leaves which were used in folk medicine to treat digestive complaints, headaches, colds and chest infections. It has also been used for culinary applications and employed as a herbal tea. The Malagasy people themselves believe that the original Ravintsara tree is an indigenous species: a ‘cousin’ of the well-known C. camphora species, which has since been introduced.
ACTIONS: Antibacterial, anticatarrhal, antifungal, anti-infectious, antimicrobial, antirheumatic, antiviral, decongestant, cicatrisant (wound healer), expectorant, immune and neurotonic.
EXTRACTION: Steam distilled from the leaves of the plant.
CHARACTERISTICS: Fresh, woody, slightly floral, balsamic, eucalyptus-like scent. It blends well with eucalyptus, rosemary, bay, frankincense, cardamon, pine, cypress, juniper and citrus oils.
PRINCIPAL CONSTITUENTS: Ravintsara is akin to Eucalyptus globulus oil (as both are particularly effective for respiratory infections) due to its high 1,8-cineole content ranging from 45–55 per cent. Other major constituents include monoterpenes (sabinene 15 per cent, alpha-pinene and beta-pinene), sesquiterpenes (beta-carophyllene), monoterpenic alcohols (alpha-terpineol 7 per cent and terpineol) and esters (terpenyl acetate).
NOTE: Ravintsara essential oil contain at least 45 per cent 1,8-cineole compared to approximately 5 per cent found in Ravensara aromatica oil.
SAFETY DATA: Ravintsara oil is generally very well tolerated by the majority of the population, although like eucalyptus, it can cause sensitization in some individuals and should be used in moderation.
AROMATHERAPY/HOME: USE
Skin care: Shingles, herpes, verrucas, warts and athletes foot.
Circulation muscles and joints: Aching muscles and joints.
Respiratory system: Coughs, colds, influenza and other respiratory ailments such as asthma, bronchitis, sinusitis, laryngitis, otitis, tonsillitis and whooping cough.
Immune system: Viral infections especially air-borne infections.

OTHER USES: Ravintsara oil is produced in a ‘pharmaceutical grade’ for the chemical and perfumery industry.... ravintsara
Rosa centifolia
FAMILY: Rosaceae
SYNONYMS: Rose maroc, French rose, Provence rose, hundred-leaved rose, Moroccan otto of rose (oil), French otto of rose (oil), rose de mai (absolute or concrete).
GENERAL DESCRIPTION: The rose which is generally used for oil production is strictly a hybrid between R. centifolia, a pink rose, and R. gallica, a dark red rose. This variety, known as rose de mai, grows to a height of 2.5 metres and produces an abundance of flowers with large pink or rosy-purple petals. There are two subspecies – one is more spiny than the other.
DISTRIBUTION: The birthplace of the cultivated rose is believed to be ancient Persia; now cultivated mainly in Morocco, Tunisia, Italy, France, Yugoslavia and China. The concrete, absolute and oil are mainly produced in Morocco; the absolute in France, Italy and China.
OTHER SPECIES: There are over 10,000 types of cultivated rose! There are several subspecies of R. centifolia, depending on the country of origin. Other therapeutic species are the red rose or apothecary rose (R. gallica) of traditional Western medicine, the oriental or tea rose (R. indica), the Chinese or Japanese rose (R. rugosa) and the Turkish or Bulgarian rose (R. damascena) which is also extensively cultivated for its oil. Recently rosehip seed oil from R. rubiginosa has been found to be a very effective skin treatment; it promotes tissue regeneration and is good for scars, burns and wrinkles. The wild rose (Eubatus rubus) is now also being used to produce a rare absolute with a rich, spicy-earthy fragrance. See also entry on damask rose and the Botanical Classification section.
HERBAL/FOLK TRADITION: The healing virtues of the rose have been known since antiquity and although roses are rarely used in herbal practice nowadays, up to the Middle Ages they played an essential part in the materia medica, and still
fulfil an important role in Eastern medicine. They were used for a wide range of disorders, including digestive and menstrual problems, headaches and nervous tension, liver congestion, poor circulation, fever (plague), eye infections and skin complaints. ‘The symbolism connected with the rose is perhaps one of the richest and most complex associated with any plant ... traditionally associated with Venus, the Goddess of love and beauty, and in our materialistic age the Goddess is certainly alive and well in the cosmetics industry for rose oil (mainly synthetic) is found as a component in 46% of men’s perfumes and 98% of women’s fragrances.’.
The French or Moroccan rose possesses narcotic properties and has the reputation for being aphrodisiac (more so than the Bulgarian type), possibly due to the high percentage of phenyl ethanol in the former. For further distinctions between the different properties of rose types, see damask rose.
ACTIONS: Antidepressant, antiphlogistic, antiseptic, antispasmodic, anti-tubercular agent, antiviral, aphrodisiac, astringent, bactericidal, choleretic, cicitrisant, depurative, emmenagogue, haemostatic, hepatic, laxative, regulator of appetite, sedative (nervous), stomachic, tonic (heart, liver, stomach, uterus).
EXTRACTION: 1. Essential oil or otto by water or steam distillation from the fresh petals. (Rose water is produced as a byproduct of this process.) 2. Concrete and absolute by solvent extraction from the fresh petals. (A rose leaf absolute is also produced in small quantities in France.)
CHARACTERISTICS: 1. The oil is a pale yellow liquid with a deep, sweet, rosy-floral, tenacious odour. 2. The absolute is a reddish orange viscous liquid with a deep, rich, sweet, rosy-spicy, honeylike fragrance. It blends well with jasmine, cassie, mimosa, neroli, geranium, bergamot, lavender, clary sage, sandalwood, guaiacwood, patchouli, benzoin, chamomile, Peru balsam, clove and palmarosa.
PRINCIPAL CONSTITUENTS: It has over 300 constituents, some in minute traces. Mainly citronellol (18–22 per cent), phenyl ethanol (63 per cent), geraniol and nerol (10–15 per cent), stearopten (8 per cent), farnesol (0.2–2 per cent), among others.

The concrete, absolute and oil are employed extensively in soaps, cosmetics, toiletries and perfumes of all types – floral, oriental, chypres, etc. Some flavouring uses, especially fruit products and tobacco.... rose, cabbage
Aniba rosaeodora
FAMILY: Lauraceae
SYNONYMS: A. rosaeodora var. amazonica, bois de rose, Brazilian rosewood.
GENERAL DESCRIPTION: Medium-sized, tropical, evergreen tree with a reddish bark and heartwood, bearing yellow flowers. Used extensively for timber. NB: This is one of the trees that is being extensively felled in the clearing of the South American rainforests; the continual production of rosewood oil is consequently enviromentally damaging.
DISTRIBUTION: Native to the Amazon region; Brazil and Peru are the main producers.
OTHER SPECIES: There are several species of timber all known as rosewood; however, the essential oil is only distilled from the above species. French Guiana used to produce the cayenne rosewood (Ocotea caudata), which is superior in quality to the Peruvian or Brazilian type.
HERBAL/FOLK TRADITION: Used for building, carving and French cabinet making. Nowadays, most rosewood goes to Japan for the production of chopsticks.
ACTIONS: Mildly analgesic, anticonvulsant, antidepressant, antimicrobial, antiseptic, aphrodisiac, bactericidal, cellular stimulant, cephalic, deodorant, stimulant (immune system), tissue regenerator, tonic.
EXTRACTION: Essential oil by steam distillation of the wood chippings.
CHARACTERISTICS: Colourless to pale yellow liquid with a very sweet, woody-floral fragrance with a spicy hint. Blends well with most oils, especially citrus, woods and florals. It helps give body and rounds off sharp edges.
PRINCIPAL CONSTITUENTS: Linalol (90–97 per cent) in cayenne rosewood; in the Brazilian oil slightly less (80–90 per cent). Also cineol, terpineol, geraniol, citronella!, limonene, pinene, among others.
SAFETY DATA: Non-toxic, non-irritant, nonsensitizing.
AROMATHERAPY/HOME: USE
Skin care: Acne, dermatitis, scars, wounds, wrinkles and general skin care: sensitive, dry, dull, combination oily/dry, etc. ‘Although it does not have any dramatic curative power ... I find it very useful especially for skin care. It is very mild and safe to use.’.
Immune system: Colds, coughs, fever, infections, stimulates the immune system.
Nervous system: Frigidity, headaches, nausea, nervous tension and stress-related conditions.
OTHER USES: Once extensively used as a source of naturallinalol, now increasingly replaced by the synthetic form. Acetylated rosewood oil is used extensively in perfumery work – soaps, toiletries, cosmetics and perfumes. The oil is employed in most major food categories, alcoholic and soft drinks.... rosewood
