Chickenpox

Also known as varicella. An acute, contagious disease predominantly of children – although it may occur at any age – characterised by fever and an eruption on the skin. The name, chickenpox, is said to be derived from the resemblance of the eruption to boiled chickpeas.

Causes The disease occurs in epidemics affecting especially children under the age of ten years. It is due to the varicella zoster virus, and the condition is an extremely infectious one from child to child. Although an attack confers life-long immunity, the virus may lie dormant and manifest itself in adult life as HERPES ZOSTER or shingles.

Symptoms There is an incubation period of 14–21 days after infection, and then the child becomes feverish or has a slight shivering, or may feel more severely ill with vomiting and pains in the back and legs. Almost at the same time, an eruption consisting of red pimples which quickly change into vesicles ?lled with clear ?uid appears on the back and chest, sometimes about the forehead, and less frequently on the limbs. These vesicles appear over several days and during the second day may show a change of their contents to turbid, purulent ?uid. Within a day or two they burst, or, at all events, shrivel up and become covered with brownish crusts. The small crusts have all dried up and fallen o? in little more than a week and recovery is almost always complete.

Treatment The fever can be reduced with paracetamol and the itching soothed with CALAMINE lotion. If the child has an immune disorder, is suffering from a major complication such as pneumonia, or is very unwell, an antiviral drug (aciclovir) can be used. It is likely to be e?ective only at an early stage. A vaccine is available in many parts of the world but is not used in the UK; the argument against its use is that it may delay chickenpox until adult life when the disease tends to be much more severe.... chickenpox

Herpes

A small group of capsid-forming DNA viruses, sometimes divided into Type I (forming vesicles and blisters on the mouth, lips-generally above the waist) and Type II (usually sexually transmitted, with symptoms mostly below the waist). Both types form acute initial outbreaks, go dormant, reactivate, and so forth. For most folks, frequent outbreaks are clear signs of stress or immunosuppression. Both types are EQUALLY dangerous for infants.... herpes

Spore

Part of the lifecycle of certain BACTERIA when the vegetative cell is encapsulated and metabolism falls to a low level. The spore is resistant to changes in the environment and, when these are unfavourable, the spore remains dormant; when they improve, it starts to grow. Certain dangerous bacteria, such as CLOSTRIDIUM, produce resistant ubiquitous spores, so sterilisation procedures need to be very e?ective.... spore

Herpes Zoster

Shingles. An acute inflammatory virus infection of one or more posterior root ganglion of the spine, or of the trigeminal nerve. Caused by a DNA virus (varicella zoster). May be due to re-activation of the chicken-pox virus which lies latent in the ganglia of sensory and somatic nerves and present in the body from childhood infection. Severe in the elderly. Should be distinguished from herpes simplex. Shingles cannot be re-activated by close proximity of a case, but may be caught by direct contact with a burst blister.

Symptoms: Two-to-four-day fever precedes a red rash which develops into clear blisters. Blisters dry up to form scabs that drop off leaving scars. Lesions and pain follow the path of the infected nerve. Pain described as intense, burning, itching: may persist for months as post-herpetic neuralgia. When virus affects the fifth cranial nerve vision will be impaired. In the elderly it may reveal some underlying malignancy. Patients having chemotherapy or radiotherapy are at risk.

Alternatives. Specific anti-viral therapy. Remedies in general use: Asafoetida, Jamaica Dogwood, Marigold, Mistletoe, Nettles, Passion flower, Poke root, Queen’s Delight, Valerian, Wild Lettuce, Wild Yam. St John’s Wort plays a role in reducing the long-lasting neuralgia. Echinacea imparts strength to endure the ordeal. The addition of a stomachic remedy (Gentian) to a prescription may prove beneficial. Mild short-term analgesics include: Oats, Valerian, Asafoetida, Passion flower, Wild Lettuce, Hops.

Bone, Disorders Of

Bone is not an inert sca?olding for the human body. It is a living, dynamic organ, being continuously remodelled in response to external mechanical and chemical in?uences and acting as a large reservoir for calcium and phosphate. It is as susceptible to disease as any other organ, but responds in a way rather di?erent from the rest of the body.

Bone fractures These occur when there is a break in the continuity of the bone. This happens either as a result of violence or because the bone is unhealthy and unable to withstand normal stresses.

SIMPLE FRACTURES Fractures where the skin remains intact or merely grazed. COMPOUND FRACTURES have at least one wound which is in communication with the fracture, meaning that bacteria can enter the fracture site and cause infection. A compound fracture is also more serious than a simple fracture because there is greater potential for blood loss. Compound fractures usually need hospital admission, antibiotics and careful reduction of the fracture. Debridement (cleaning and excising dead tissue) in a sterile theatre may also be necessary.

The type of fracture depends on the force which has caused it. Direct violence occurs when an object hits the bone, often causing a transverse break – which means the break runs horizontally across the bone. Indirect violence occurs when a twisting injury to the ankle, for example, breaks the calf-bone (the tibia) higher up. The break may be more oblique. A fall on the outstretched hand may cause a break at the wrist, in the humerus or at the collar-bone depending on the force of impact and age of the person. FATIGUE FRACTURES These occur after the bone has been under recurrent stress. A typical example is the march fracture of the second toe, from which army recruits suffer after long marches. PATHOLOGICAL FRACTURES These occur in bone which is already diseased – for example, by osteoporosis (see below) in post-menopausal women. Such fractures are typically crush fractures of the vertebrae, fractures of the neck of the femur, and COLLES’ FRACTURE (of the wrist). Pathological fractures also occur in bone which has secondary-tumour deposits. GREENSTICK FRACTURES These occur in young children whose bones are soft and bend, rather than break, in response to stress. The bone tends to buckle on the side opposite to the force. Greenstick fractures heal quickly but still need any deformity corrected and plaster of Paris to maintain the correction. COMPLICATED FRACTURES These involve damage to important soft tissue such as nerves, blood vessels or internal organs. In these cases the soft-tissue damage needs as much attention as the fracture site. COMMINUTED FRACTURES A fracture with more than two fragments. It usually means that the injury was more violent and that there is more risk of damage to vessels and nerves. These fractures are unstable and take longer to unite. Rehabilitation tends to be protracted. DEPRESSED FRACTURES Most commonly found in skull fractures. A fragment of bone is forced inwards so that it lies lower than the level of the bone surrounding it. It may damage the brain beneath it.

HAIR-LINE FRACTURES These occur when the bone is broken but the force has not been severe enough to cause visible displacement. These fractures may be easily missed. Symptoms and signs The fracture site is usually painful, swollen and deformed. There is asymmetry of contour between limbs. The limb is held uselessly. If the fracture is in the upper

limb, the arm is usually supported by the patient; if it is in the lower limb then the patient is not able to bear weight on it. The limb may appear short because of muscle spasm.

Examination may reveal crepitus – a bony grating – at the fracture site. The diagnosis is con?rmed by radiography.

Treatment Healing of fractures (union) begins with the bruise around the fracture being resorbed and new bone-producing cells and blood vessels migrating into the area. Within a couple of days they form a bridge of primitive bone across the fracture. This is called callus.

The callus is replaced by woven bone which gradually matures as the new bone remodels itself. Treatment of fractures is designed to ensure that this process occurs with minimal residual deformity to the bone involved.

Treatment is initially to relieve pain and may involve temporary splinting of the fracture site. Reducing the fracture means restoring the bones to their normal position; this is particularly important at the site of joints where any small displacement may limit movement considerably.

with plaster of Paris. If closed traction does not work, then open reduction of the fracture may

be needed. This may involve ?xing the fracture with internal-?xation methods, using metal plates, wires or screws to hold the fracture site in a rigid position with the two ends closely opposed. This allows early mobilisation after fractures and speeds return to normal use.

External ?xators are usually metal devices applied to the outside of the limb to support the fracture site. They are useful in compound fractures where internal ?xators are at risk of becoming infected.

Consolidation of a fracture means that repair is complete. The time taken for this depends on the age of the patient, the bone and the type of fracture. A wrist fracture may take six weeks, a femoral fracture three to six months in an adult.

Complications of fractures are fairly common. In non-union, the fracture does not unite

– usually because there has been too much mobility around the fracture site. Treatment may involve internal ?xation (see above). Malunion means that the bone has healed with a persistent deformity and the adjacent joint may then develop early osteoarthritis.

Myositis ossi?cans may occur at the elbow after a fracture. A big mass of calci?ed material develops around the fracture site which restricts elbow movements. Late surgical removal (after 6–12 months) is recommended.

Fractured neck of FEMUR typically affects elderly women after a trivial injury. The bone is usually osteoporotic. The leg appears short and is rotated outwards. Usually the patient is unable to put any weight on the affected leg and is in extreme pain. The fractures are classi?ed according to where they occur:

subcapital where the neck joins the head of the femur.

intertrochanteric through the trochanter.

subtrochanteric transversely through the upper end of the femur (rare). Most of these fractures of the neck of femur

need ?xing by metal plates or hip replacements, as immobility in this age group has a mortality of nearly 100 per cent. Fractures of the femur shaft are usually the result of severe trauma such as a road accident. Treatment may be conservative or operative.

In fractures of the SPINAL COLUMN, mere damage to the bone – as in the case of the so-called compression fracture, in which there is no damage to the spinal cord – is not necessarily serious. If, however, the spinal cord is damaged, as in the so-called fracture dislocation, the accident may be a very serious one, the usual result being paralysis of the parts of the body below the level of the injury. Therefore the higher up the spine is fractured, the more serious the consequences. The injured person should not be moved until skilled assistance is at hand; or, if he or she must be removed, this should be done on a rigid shutter or door, not on a canvas stretcher or rug, and there should be no lifting which necessitates bending of the back. In such an injury an operation designed to remove a displaced piece of bone and free the spinal cord from pressure is often necessary and successful in relieving the paralysis. DISLOCATIONS or SUBLUXATION of the spine are not uncommon in certain sports, particularly rugby. Anyone who has had such an injury in the cervical spine (i.e. in the neck) should be strongly advised not to return to any form of body-contact or vehicular sport.

Simple ?ssured fractures and depressed fractures of the skull often follow blows or falls on the head, and may not be serious, though there is always a risk of damage which is potentially serious to the brain at the same time.

Compound fractures may result in infection within the skull, and if the skull is extensively broken and depressed, surgery is usually required to check any intercranial bleeding or to relieve pressure on the brain.

The lower jaw is often fractured by a blow on the face. There is generally bleeding from the mouth, the gum being torn. Also there are pain and grating sensations on chewing, and unevenness in the line of the teeth. The treatment is simple, the line of teeth in the upper jaw forming a splint against which the lower jaw is bound, with the mouth closed.

Congenital diseases These are rare but may produce certain types of dwar?sm or a susceptibility to fractures (osteogenesis imperfecta).

Infection of bone (osteomyelitis) may occur after an open fracture, or in newborn babies with SEPTICAEMIA. Once established it is very di?cult to eradicate. The bacteria appear capable of lying dormant in the bone and are not easily destroyed with antibiotics so that prolonged treatment is required, as might be surgical drainage, exploration or removal of dead bone. The infection may become chronic or recur.

Osteomalacia (rickets) is the loss of mineralisation of the bone rather than simple loss of bone mass. It is caused by vitamin D de?ciency and is probably the most important bone disease in the developing world. In sunlight the skin can synthesise vitamin D (see APPENDIX 5: VITAMINS), but normally rickets is caused by a poor diet, or by a failure to absorb food normally (malabsorbtion). In rare cases vitamin D cannot be converted to its active state due to the congenital lack of the speci?c enzymes and the rickets will fail to respond to treatment with vitamin D. Malfunction of the parathyroid gland or of the kidneys can disturb the dynamic equilibrium of calcium and phosphate in the body and severely deplete the bone of its stores of both calcium and phosphate.

Osteoporosis A metabolic bone disease resulting from low bone mass (osteopenia) due to excessive bone resorption. Su?erers are prone to bone fractures from relatively minor trauma. With bone densitometry it is now possible to determine individuals’ risk of osteoporosis and monitor their response to treatment.

By the age of 90 one in two women and one in six men are likely to sustain an osteoporosis-related fracture. The incidence of fractures is increasing more than would be expected from the ageing of the population, which may re?ect changing patterns of exercise or diet.

Osteoporosis may be classi?ed as primary or secondary. Primary consists of type 1 osteoporosis, due to accelerated trabecular bone loss, probably as a result of OESTROGENS de?ciency. This typically leads to crush fractures of vertebral bodies and fractures of the distal forearm in women in their 60s and 70s. Type 2 osteoporosis, by contrast, results from the slower age-related cortical and travecular bone loss that occurs in both sexes. It typically leads to fractures of the proximal femur in elderly people.

Secondary osteoporosis accounts for about 20 per cent of cases in women and 40 per cent of cases in men. Subgroups include endocrine (thyrotoxicosis – see under THYROID GLAND, DISEASES OF, primary HYPERPARATHYROIDISM, CUSHING’S SYNDROME and HYPOGONADISM); gastrointestinal (malabsorption syndrome, e.g. COELIAC DISEASE, or liver disease, e.g. primary biliary CIRRHOSIS); rheumatological (RHEUMATOID ARTHRITIS or ANKYLOSING SPONDYLITIS); malignancy (multiple MYELOMA or metastatic CARCINOMA); and drugs (CORTICOSTEROIDS, HEPARIN). Additional risk factors for osteoporosis include smoking, high alcohol intake, physical inactivity, thin body-type and heredity.

Individuals at risk of osteopenia, or with an osteoporosis-related fracture, need investigation with spinal radiography and bone densitometry. A small fall in bone density results in a large increase in the risk of fracture, which has important implications for preventing and treating osteoporosis.

Treatment Antiresorptive drugs: hormone replacement therapy – also valuable in treating menopausal symptoms; treatment for at least ?ve years is necessary, and prolonged use may increase risk of breast cancer. Cyclical oral administration of disodium etidronate – one of the bisphosphonate group of drugs – with calcium carbonate is also used (poor absorption means the etidronate must be taken on an empty stomach). Calcitonin – currently available as a subcutaneous injection; a nasal preparation with better tolerance is being developed. Calcium (1,000 mg daily) seems useful in older patients, although probably ine?ective in perimenopausal women, and it is a safe preparation. Vitamin D and calcium – recent evidence suggests value for elderly patients. Anabolic steroids, though androgenic side-effects (masculinisation) make these unacceptable for most women.

With established osteoporosis, the aim of treatment is to relieve pain (with analgesics and physical measures, e.g. lumbar support) and reduce the risk of further fractures: improvement of bone mass, the prevention of falls, and general physiotherapy, encouraging a healthier lifestyle with more daily exercise.

Further information is available from the National Osteoporosis Society.

Paget’s disease (see also separate entry) is a common disease of bone in the elderly, caused by overactivity of the osteoclasts (cells concerned with removal of old bone, before new bone is laid down by osteoblasts). The bone affected thickens and bows and may become painful. Treatment with calcitonin and bisphosphonates may slow down the osteoclasts, and so hinder the course of the disease, but there is no cure.

If bone loses its blood supply (avascular necrosis) it eventually fractures or collapses. If the blood supply does not return, bone’s normal capacity for healing is severely impaired.

For the following diseases see separate articles: RICKETS; ACROMEGALY; OSTEOMALACIA; OSTEOGENESIS IMPERFECTA.

Tumours of bone These can be benign (non-cancerous) or malignant (cancerous). Primary bone tumours are rare, but secondaries from carcinoma of the breast, prostate and kidneys are relatively common. They may form cavities in a bone, weakening it until it breaks under normal load (a pathological fracture). The bone eroded away by the tumour may also cause problems by causing high levels of calcium in the plasma.

EWING’S TUMOUR is a malignant growth affecting long bones, particularly the tibia (calfbone). The presenting symptoms are a throbbing pain in the limb and a high temperature. Treatment is combined surgery, radiotherapy and chemotherapy.

MYELOMA is a generalised malignant disease of blood cells which produces tumours in bones which have red bone marrow, such as the skull and trunk bones. These tumours can cause pathological fractures.

OSTEOID OSTEOMA is a harmless small growth which can occur in any bone. Its pain is typically removed by aspirin.

OSTEOSARCOMA is a malignant tumour of bone with a peak incidence between the ages of ten and 20. It typically involves the knees, causing a warm tender swelling. Removal of the growth with bone conservation techniques can often replace amputation as the de?nitive treatment. Chemotherapy can improve long-term survival.... bone, disorders of

Interleukins

Interleukins are lymphokines – that is, polypeptides produced by activated lymphocytes. They are involved in signalling between cells of the immune system (see IMMUNITY) and are released by several cell types, including lymphocytes. They interact to control the immune response of cells and also participate in HAEMOPOIESIS. There are seven varieties, interleukins 1 to 7. For example, interleukin 1 is produced as a result of in?ammation and stimulates the proliferation of T and B lymphocytes, enhancing the immune response by stimulating other lymphocytes and activating dormant T cells. Interleukin 2 has anti-cancer effects as it is able to activate T lymphocytes to become killer cells which destroy foreign antigens (see ANTIGEN) such as cancer cells, and this anti-cancer e?ect is being developed for clinical use. The remaining interleukins have a range of properties in cell growth and di?erentiation.... interleukins

Anthrax

A serious bacterial infection of livestock that occasionally spreads to humans. In humans, the most common form of the infection is cutaneous anthrax, which affects the skin. Another form, pulmonary anthrax, affects the lungs. Anthrax is caused by BACILLUS ANTHRACIS. This microorganism produces spores that can remain dormant for years in soil and animal products and are capable of reactivation. Animals become infected by grazing on contaminated land. People may become infected via a scratch or sore if they handle materials from infected animals. Pulmonary anthrax occurs as a result of inhaling spores from animal fibres.

In cutaneous anthrax, a raised, itchy, area develops at the site of entry of the spores, progressing to a large blister and finally a black scab, with swelling of the surrounding tissues.

This is treatable with penicillin in its early stages.

Without treatment, the infection may spread to lymph nodes and the bloodstream, and may be fatal.

Pulmonary anthrax causes severe breathing difficulty and is fatal in most cases.... anthrax

Cold Sore

A small skin blister, usually around the mouth, commonly caused by a strain of the herpes simplex virus called HSV1 (herpes simplex virus type 1). The first attack of the virus may be symptomless or may cause a flu-like illness with painful mouth and lip ulcers called gingivostomatis. The virus then lies dormant in nerve cells, but may occasionally be reactivated and cause cold sores. Reactivation may occur after exposure to hot sunshine or a cold wind, during a common cold or other infection, or in women around the time of their menstrual periods. Prolonged attacks can occur in people with reduced immunity to infection due to illness or treatment with immunosuppressant drugs.

In many cases, an outbreak of cold sores is preceded by tingling in the lips, followed by the formation of small blisters that enlarge, causing itching and soreness. Within a few days they burst and become encrusted. Most disappear within a week. The antiviral drug aciclovir in a cream may prevent cold sores if used at the first sign of tingling.... cold sore

Dendritic Ulcer

a branching ulcer of the surface of the cornea caused by *herpes simplex virus. A similar appearance may be produced by a healing corneal abrasion. Dendritic ulcers tend to recur because the virus lies dormant in the corneal sensory nerves; years may elapse between recurrences.... dendritic ulcer

Germinal Epithelium

the epithelial covering of the ovary, which was formerly thought to be the site of formation of *oogonia. It is now thought that the oogonia persist in a dormant state from the prenatal period until required in reproductive life.... germinal epithelium

Importance: Glory lily is a glabrous herbaceous climber which yields different types of troplone alkaloids of medicinal importance. The major alkaloids are colchicine , 3-demethyl colchicine and colchicoside. There is another alkaloid gloriosine which promises to be even more effective than colchicine in plant breeding for inducing polyploidy. The genus has importance in the ornamental horticulture due to its bright flowers and wiry climbing stem.

The roots and rhizomes are used in traditional system of medicine. Its abortifacient and antipyretic properties have been mentioned in ancient classics “Charaka”. The name Garbhaghatini is due to this abortifacient activity. They are useful in the treatment of inflammations, ulcers, scrofula, hemorrhoids, pruritus, dyspepsia, helminthiasis, flatulence, intermittent fevers and debility. The root is given internally as an effective antidote against cobra poison. A paste of the root is also used as an anodyne; applications in bites of poisonous insects, snake bites, scorpion sting, parasitic skin diseases and leprosy (Nadkarni,1954; Chaudhuri and Thakur; 1994).

Distribution: The plant is distributed throughout tropical India upto an altitude of 2500m and in Andaman islands. It is also cultivated in tropical and South Africa, Madagaskar, Indonesia and Malasia. It is reported to be cultivated in some parts of Europe. In India it was cultivated in RRL, Jammu in 1960s. Recently it was taken up by Indian Council of Agricultural Research(ICAR). Cultivation of the plant is mostly confined to the Southern states of India besides its collection from wild sources.

Botany: Gloriosa superba Linn. belongs to Liliaceae family. It is a glabrous climbing herb with tuberous root stock grows over hedges and small trees. Stem is 6m long which grows to a height of 1.2-1.5m before the stem branches. Leaves are simple, alternate or whorled, sessile, ovate-lanceolate, 17x4.5cm, tip elongating into a spirally coiled tendril, base cordate and margin entire. Flowers are large in terminal racemes; perianth segments 6, linear, flexuosus and deflexed, basal half bright yellow, upper half red; stamens 6; ovary glabrous, 3-celled. Fruits are capsules, linear-oblong, upto 6.8cm long, 3 equal lobes, one or two lobes shorter in malformed fruits; green dried to pale and then black colour, dehisced into three sections. Seeds are oval in shape, testa spongy, embryo cylindric, 30-150 seeds per capsule, pale orange attached to the sutures. Tubers are cylindric, large, simple, ‘V’ shaped with the two limps equal or unequal in lenth pointed towards end brownish externally and yellowish internally. (Narain, 1977)

Agrotechnology: This is a rainy season plant and sprouts well in warm, humid and tropical conditions. It should be grown in sun as the plants in shade become weedy and thin and move towards light. G. superba is a shallow rooted plant and grows well in a variety of soils either clay or sand through out India. It grows well in a light porous soil with good drainage. For vigorous growth, greater blooms and strong tuber, a mixture of soil, sand and compost manure is recommended. The propagation is mainly by tubers, by division of rhizomes. Seeds remain dormant for 6-9 months and due to hard seed coat, about 20-30 days are required for germination and seeds may take 3-4 years before it matures to flower. Treatment of seeds by gibberellin(1-3 ppm) resulted in higher yield of colchicine in the plant and higher production of tubers. In tissue culture, young sprouts are cultured on Murashige and Skoog’s medium (Msb) supplemented with kinetin (1-4 mg/l). Direct regeneration of the explants are obtained.

The seeds and rhizomes are sown usually in the last week of June to mid July. The rhizomes are planted by splitting carefully into two from their ‘V’ shaped joints (two buds being at the extreme end of each rhizome) in lines 20cm apart at a distance of 20cm (while seeds are sown in lines at a distance of 4-6cm apart). They are watered regularly when the plants are growing. After green shoots appear 2-3 showers are weekly. The irradiation of the plant at 42% natural sunlight intensity increased the production of tuber and colchicine. They usually takes 6-10 weeks to flower after sprouting and then set on fruits. The fruits ripen at the end of October and after that aerial shoot eventually dies, leaving the fleshy tubers underground. The tubers are dug out with great care. An individual plant produces 50g tubers on an average. The average yield is approximately 4000-5000kg of rhizomes and 1000 kg of seed per hectare. The content of colchicine is usually 0.358% and 1.013% in tubers and seeds, respectively.

Post harvest technology: Lixivation of the material is done with 70% ethyl alcohol. Concentrated under vacuum to one third of its volume and extracted with chloroform for colchicine and related substances-concentration of the aqueous phase to syrup which is extracted 6-8 times with a mixture of CHCl3 - alcohol (4:1) to yield colchicoside.

Properties and activity: The flowers, leaves and tubers contain colchicine, superbin, N-formyl deacetyl colchicine, demethyl colochicine and lumicolchicine. Tubers also contain gloriosine. Leaves in addition, contain chelidonic acid, 2-hydroxy 6-methoxy benzoic acid and -sitosterol glucoside. Colchicine, demethyl colchicine and colchicoside have been reported from seeds. Rhizome is oxytocic, anticancerous, antimalarial, stomachic, purgative, cholagogue, anthelmintic, alterative, febrifuge and antileprotic. Leaf is antiasthmatic and antiinflammatory. Root shows antigonorrhoeic and antibiotic activity. This plant has poisonous effect to enviroment and livestock. The toxic properties are due to presence of alkaloids chiefly colchicine (Clewer et al, 1915).... glory lily

Rauvolfia serpentina

Apocynaceae

San: Sarpagandha

Tam: Chivan amelpodi

Kan: Sutranbhi

Tel: Patalagandhi

Introduction: Serpentwood is an erect, evergreen , perennial undershrub whose medicinal use has been known since 3000 years. Its dried root is the economical part which contains a number of alkaloids of which reserpine, rescinnamine, deserpidine, ajamalacine, ajmaline, neoajmalin, serpentine, -yohimbine are pharmacologically important. The root is a sedative and is used to control high blood pressure and certain forms of insanity. In Ayurveda it is also used for the treatment of insomnia, epilepsy, asthma, acute stomach ache and painful delivery. It is used in snake-bite, insect stings, and mental disorders. It is popular as “Madman’s medicine” among tribals. ‘Serpumsil’ tablet for high blood pressure is prepared from Rauvolfia roots. Reserpine is a potent hypotensive and tranquillizer but its prolonged usage stimulates prolactine release and causes breast cancer. The juice of the leaves is used as a remedy for the removal of opacities of the cornea.

Distribution: Rauvolfia serpentina is native to India. Several species of Rauvolfia are observed growing under varying edaphoclimatic conditions in the humid tropics of India, Nepal, Burma, Thailand, Bangladesh, Indonesia , Cambodia, Philippines and Sri Lanka. In India, it is cultivated in the states of Uttar Pradesh, Bihar, Tamil Nadu, Orissa, Kerala, Assam, West Bengal and Madhya Pradesh (Dutta and Virmani, 1964). Thailand is the chief exporter of Rauvolfia alkaloids followed by Zaire, Bangladesh, Sri Lanka, Indonesia and Nepal. In India, it has become an endangered species and hence the Government has prohibited the exploitation of wild growing plants in forest and its export since 1969.

Botany: Plumier in 1703 assigned the name Rauvolfia to the genus in honour of a German physcian -Leonhart Rauvolf of Augsburg. The genus Rauvolfia of Apocynaceae family comprises over 170 species distributed in the tropical and subtropical parts of the world including 5 species native to India. The common species of the genus Rauvolfia and their habitat as reported by Trivedi (1995) are given below.

Roots nearly verticle, tapering up to 15 cm thick at the crown and long giving a serpent-like appearance, occasionally branched or tortuous developing small fibrous roots. Roots greenish-yellow externally and pale yellow inside, extremely bitter in taste. Leaves born in whorls of 3-4 elliptic-lanceolate or obovate, pointed. Flowers numerous borne on terminal or axillary cymose inflorscence. Corolla tubular, 5-lobed, 1-3 cm long, whitish-pink in colour. Stamens 5, epipetalous. Carpels 2, connate, style filiform with large bifid stigma. Fruit is a drupe, obliquely ovoid and purplish black in colour at maturity with stone containing 1-2 ovoid wrinkled seeds. The plant is cross-pollinated, mainly due to the protogynous flowers (Sulochana ,1959).

Agrotechnology: Among the different species of Rauvolfia, R. serpentina is preferred for cultivation because of higher reserpine content in the root. Though it grows in tropical and subtropical areas which are free from frost, tropical humid climate is most ideal. Its common habitats receive an annual rain fall of 1500-3500 mm and the annual mean temperature is 10-38 C. It grows up to an elevation of 1300-1400m from msl. It can be grown in open as well as under partial shade conditions. It grows on a wide range of soils. Medium to deep well drained fertile soils and clay-loam to silt-loam soils rich in organic matter are suitable for its cultivation. It requires slightly acidic to neutral soils for good growth.

The plant can be propagated vegetatively by root cuttings, stem cuttings or root stumps and by seeds. Seed propagation is the best method for raising commercial plantation. Seed germination is very poor and variable from 10-74%. Seeds collected during September to November give good results. It is desirable to use fresh seeds and to sock in 10% sodium chloride solution. Those seeds which sink to the bottom should only be used. Seeds are treated with ceresan or captan before planting in nursery to avoid damping off. Seed rate is 5-6 kg/ha. Nursery beds are prepared in shade, well rotten FYM is applied at 1kg/m2 and seeds are dibbled 6-7cm apart in May-June and irrigated.

Two months old seedlings with 4-6 leaves are transplanted at 45-60 x 30 cm spacing in July -August in the main field. Alternatively, rooted cuttings of 2.5-5cm long roots or 12-20cm long woody stems can also be used for transplanting. Hormone (Seradix) treatment increases rooting. In the main field 10-15 t/ha of FYM is applied basally. Fertilisers are applied at 40:30:30kg N: P2O5 :K2O/ha every year. N is applied in 2-3 splits. Monthly irrigation increases the yield. The nursery and the main field should be kept weed free by frequent weeding and hoeing. In certain regions intercroping of soybean, brinjal, cabbage, okra or chilly is followed in Rauvolfia crop.

Pests like root grubs (Anomala polita), moth (Deilephila nerii), caterpillar (Glyophodes vertumnalis), black bugs and weevils are observed on the crop, but the crop damage is not serious. The common diseases reported are leaf spot (Cercospora rauvolfiae, Corynespora cassiicola), leaf blotch (Cercospora serpentina), leaf blight (Alternaria tenuis), anthracnose (Colletotrichum gloeosporioides), die back (Colletotrichum dematrium), powdery mildew (Leviellula taurica), wilt (Fusarium oxysporum), root-knot (Meloidogyne sp.), mosaic and bunchy top virus diseases. Field sanitation, pruning and burning of diseased parts and repeated spraying of 0.2% Dithane Z-78 or Dithane M-45 are recommended for controlling various fungal diseases. Rauvolfia is harvested after 2-3 years of growth. The optimum time of harvest is in November -December when the plants shed leaves, become dormant and the roots contain maximum alkaloid content. Harvesting is done by digging up the roots by deeply penetrating implements (Guniyal et al, 1988).

Postharvest technology: The roots are cleaned washed cut into 12-15cm pieces and dried to 8-10% moisture.

The dried roots are stored in polythene lined gunny bags in cool dry place to protect it from mould. The yield is 1.5-2.5 t/ha of dry roots. The root bark constitutes 40-45% of the total weight of root and contributes 90% of the total alkaloids yield.

Properties and activity: Rauvolfia root is bitter, acrid, laxative, anthelmintic, thermogenic, diuretic and sedative. Over 200 alkaloids have been isolated from the plant. Rauvolfia serpentina root contains 1.4-3% alkaloids. The alkaloids are classsified into 3 groups, viz, reserpine, ajmaline and serpentine groups. Reserpine group comprising reserpine, rescinnamine, deserpine etc act as hypotensive, sedative and tranquillising agent. Overdose may cause diarrhoea, bradycardia and drowsiness. Ajmaline, ajmalicine, ajmalinine, iso-ajmaline etc of the ajmaline group stimulate central nervous system, respiration and intestinal movement with slight hypotensive activity. Serpentine group comprising serpentine, sepentinine, alstonine etc is mostly antihypertensive. (Husain,1993; Trivedi, 1995; Iyengar, 1985).... serpentwood

Cancer – Womb

The second most common cancer in women. The alarming aspect of national health is the almost epidemic increase of cervical malignancy in younger women due to frequency of coitus, promiscuity, early coitus and contact with the herpes virus. All are mostly squamous cell carcinoma. Research studies have demonstrated a link between cigarette smoking and cancer of the cervix. (Dr Dan Hellberg)

Symptoms. Low backache, bleeding after intercourse, between periods or after ‘the change’. Abdominal swelling after 40 years of age. Sixty per cent of patients have no symptoms. Malodorous vaginal discharge. A positive cervical “pap” smear or cone-shaped biopsy examined by a pathologist confirms. Vaginal bleeding occurs in the later stages.

A letter in the New England Journal of Medicine suggests a strong link between increased risk of cervical cancer and cigarette smoking, nicotine being detected in the cervical fluids of cigarette smokers. This form of cancer is almost unknown in virgins living in closed communities such as those of the Church.

Conventional treatment is usually hysterectomy. Whatever treatment is adopted little ground is lost by supportive cleansing herbal teas. Mullein for pain.

Sponges loaded with powdered Goldenseal held against the cervix with a contraceptive cap can give encouraging results. Replace after three days. Vitamin A supplements are valuable to protect against the disease. The vitamin may also be applied topically in creams.

This form of cancer resists chemical treatment, but has been slowed down and halted by Periwinkle (Vinchristine) without damaging normal cells.

G.B. Ibotson, MD, reported disappearance of cancer of the cervix by infusions of Violet leaves by mouth and by vaginal injection. (Lancet 1917, i, 224)

In a study group of cervical cancer patients it was found that women with carcinoma in situ (CIS) were more likely to have a total Vitamin A intake below the pooled median (3450iu). Vitamin A supplementation is indicated together with zinc. (Bio-availability of Vitamin A is linked with zinc levels.) Vitamin A and zinc may be applied topically in creams and ointments.

Orthodox treatment: radiotherapy, chemotherapy, hysterectomy. As oestrogen can stimulate dormant cells the surgeon may wish to remove ovaries also. Whatever the decision, herbal supportive treatment may be beneficial. J.T Kent, MD, recommends Thuja and Shepherd’s Purse. Agents commonly indicated: Echinacea, Wild Indigo, Thuja, Mistletoe, Wild Yam. Herbal teas may be taken with profit. Dr Alfred Vogel advises Mistletoe from the oak (loranthus europaeus).

Herpes Simplex

A common viral infection, characterized by small, fluid-filled blisters. Herpes simplex infections are contagious and usually spread by direct contact. The virus has 2 forms, HSV1 (herpes simplex virus, type 1) and HSV2 (herpes simplex virus, type 2).

Most people are infected with HSV1 at some point in their lives, usually during childhood. The initial infection may be symptomless, or may cause a flu-like illness with mouth ulcers. Thereafter, the virus remains dormant in nerve cells in the facial area. In many people, the virus is periodically reactivated, causing cold sores. Rarely, the virus infects the fingers, causing a painful eruption called a herpetic whitlow. HSV1 may produce eczema herpeticum (an extensive rash of skin blisters) in a person with a preexisting skin disorder, such as eczema. Eczema herpeticum may require hospital admission. If the virus gets into an eye, it may cause conjunctivitis or a corneal ulcer. Rarely, HSV1 spreads to the brain, leading to encephalitis. The virus may cause a potentially fatal generalized infection in a person with an immunodeficiency disorder or in someone taking immunosuppressant drugs. HSV2 is the usual cause of sexually transmitted genital herpes (see herpes, genital).

Treatment of herpes simplex depends on its type, site, and severity.

Antiviral drugs, such as aciclovir, may be helpful, particularly if used early in an infection.... herpes simplex

Tuberculosis

An infectious disease, commonly called , caused in humans by the bacterium MYCOBACTERIUM TUBERCULOSIS. is usually transmitted in airborne droplets expelled when an infected person coughs or sneezes. An inhaled droplet enters the lungs and the bacteria begin multiplying. The immune system usually seals off the infection at this point, but in about 5 per cent of cases the infection spreads to the lymph nodes. It may also spread to other organs through the bloodstream, which may lead to miliary tuberculosis, a potentially fatal form of the disease.

In about another 5 per cent of cases, bacteria held in a dormant state by the immune system become reactivated months, or even years, later. The infection may then progressively damage the lungs, forming cavities.

The primary infection is usually without symptoms. Progressive infection in the lungs causes coughing (sometimes bringing up blood), chest pain, shortness of breath, fever and sweating, poor appetite, and weight loss. Pleural effusion or pneumothorax may develop. The lung damage may be fatal.

A diagnosis is made from the symptoms and signs, from a chest X-ray, and from tests on the sputum. Alternatively, a bronchoscopy may also be carried out to obtain samples for culture.

Treatment is usually with a course of 3 or 4 drugs, taken daily for 2 months, followed by daily doses of isoniazid and rifampicin for 4–6 months. However, bacteria are increasingly resistant to the drugs used in treatment, and others may have to be used and treatment carried out for a longer period. If the full course of drugs is taken, most patients recover.

can be prevented by BCG vaccination, which is offered routinely at birth or age 10–14.

Any contacts of an infected person are traced and examined, and, if infected, are treated early to reduce the risk of the infection spreading.... tuberculosis

Cyst

n. 1. an abnormal sac or closed cavity lined with *epithelium and filled with liquid or semisolid matter. There are many varieties of cysts occurring in different parts of the body. Retention cysts arise when the outlet of a glandular duct is blocked, as in *sebaceous cysts. Some cysts are congenital, due to abnormal embryonic development; for example, *dermoid cysts. Others are tumours containing cells that secrete mucus or other substances, and another type of cyst is formed by parasites in the body (see hydatid). Cysts may occur in the jaws: a periapical cyst occurs at the apex of a tooth, a dentigerous cyst occurs around the crown of an unerupted tooth, and an eruption cyst forms over an erupting tooth. See also fimbrial cyst; ovarian cyst; pseudocyst. 2. a dormant stage produced during the life cycle of certain protozoan parasites of the alimentary canal, including *Giardia and *Entamoeba. Cysts, passed out in the faeces, have tough outer coats that protect the parasites from unfavourable conditions. The parasites emerge from their cysts when they are eaten by a new host. 3. a structure formed by and surrounding the larvae of certain parasitic worms.... cyst
