White fat Health Dictionary

(CFS) is a recently designated semi-disease, often attributed to EBV (the Epstein-Barr virus) or CMV (Cytomegalovirus) infections, characterized by FUOs (Fevers of Unknown Origin) and resulting in the patient suffering FLS (Feels Like Shit). In most of us, the microorganisms involved in CFS usually provoke nothing more than a head cold; in some individuals, however, they induce a long, grinding, and debilitating disorder, characterized by exhaustion, depression, periodic fevers...a crazy-quilt of symptoms that frustrates both the sufferer and the sometimes skeptical physician. MCS (Multiple Chemical Sensitivities) are another syndrome that is often lumped with CFS, and they may often be two faces of the same condition. I am not using all these acronyms to mock the conditions, but as an irony. There is too much (Acronym Safety Syndrome) in medicine, reducing complex and frustrating conditions to insider’s techno-babble, somehow therein trivializing otherwise complex, painful and crazy-making problems. The widest use of acronyms (AIDS, HIV, CFS, MCS, MS etc.) seems to be for diseases hardest to treat, least responsive to procedural medicine, and most depressing to discuss with patients or survivors.... chronic fatigue syndrome

Tiredness: a physiological state in which muscles become fatigued by the LACTIC ACID accumulating in them as the result of their activity. For the removal of lactic acid in the recovery phase of muscular contraction, oxygen is needed. If the supply of oxygen is not plentiful enough, or cannot keep pace with the work the muscle is doing, then lactic acid accumulates and fatigue results. There is also a nervous element in muscular fatigue: it is diminished by stimulation of the sympathetic nervous system. (See also MUSCLE.)

Chronic fatigue is a symptom of some illnesses such as ANAEMIA, CHRONIC FATIGUE SYNDROME (CFS), HYPOTHYROIDISM, MONONUCLEOSIS, MOTOR NEURONE DISEASE (MND), MYASTHENIA GRAVIS, MYALGIC ENCEPHALOMYELITIS (ME) and others. Some drugs may also produce a feeling of fatigue.... fatigue

Spasm of the blood vessels in the ?nger, resulting in a white appearance. The condition is common in RAYNAUD’S DISEASE but it can be caused by the long-term use of percussion implements such as mechanical road drills or hammers. It is a recognised industrial disease. Treatment is to remove or treat the underlying cause.... white finger

Tissue in the nervous system composed of nerve fibres (axons). White matter makes up the bulk of the cerebrum (the 2 large hemispheres of the brain) and continues down into the spinal cord; its main role is to transmit nerve impulses. (See also grey matter.)... white matter

See also MYALGIC ENCEPHALOMYELITIS (ME). A condition characterised by severe, disabling mental and physical fatigue brought on by mental or physical activity and associated with a range of symptoms including muscle pain, headaches, poor sleep, disturbed moods and impaired concentration. The prevalence of the condition is between 0.2 and 2.6 per cent of the population (depending on how investigators de?ne CFS/ME). Despite the stereotype of ‘yuppie ?u’, epidemiological research has shown that the condition occurs in all socioeconomic and ethnic groups. It is commoner in women and can also occur in children.

In the 19th century CFS was called neurasthenia. In the UK, myalgic encephalomyelitis (ME) is often used, a term originally introduced to describe a speci?c outbreak such as the one at the Royal Free Hospital, London in 1955. The term is inaccurate as there is no evidence of in?ammation of the brain and spinal cord (the meaning of encephalomyelitis). Doctors prefer the term CFS, but many patients see this as derogatory, perceiving it to imply that they are merely ‘tired all the time’ rather than having a disabling illness.

The cause (or causes) are unknown, so the condition is classi?ed alongside other ‘medically unexplained syndromes’ such as IRRITABLE BOWEL SYNDROME (IBS) and multiple chemical sensitivity – all of which overlap with CFS. In many patients the illness seems to start immediately after a documented infection, such as that caused by EPSTEIN BARR VIRUS, or after viral MENINGITIS, Q FEVER and TOXOPLASMOSIS. These infections seem to be a trigger rather than a cause: mild immune activation is found in patients, but it is not known if this is cause or e?ect. The body’s endocrine system is disturbed, particularly the hypothalamopituitary-adrenal axis, and levels of cortisol are often a little lower than normal – the opposite of what is found in severe depression. Psychiatric disorder, usually depression and/or anxiety, is associated with CFS, with rates too high to be explained solely as a reaction to the disability experienced.

Because we do not know the cause, the underlying problem cannot be dealt with e?ectively and treatments are directed at the factors leading to symptoms persisting. For example, a slow increase in physical activity can help many, as can COGNITIVE BEHAVIOUR THERAPY. Too much rest can be harmful, as muscles are rapidly weakened, but aggressive attempts at coercing patients into exercising can be counter-productive as their symptoms may worsen. Outcome is in?uenced by the presence of any pre-existing psychiatric disorder and the sufferer’s beliefs about its causes and treatment. Research continues.... chronic fatigue syndrome (cfs)

The greying or whitening of hair which takes place with age is due to a loss of its pigment, MELANIN, and the collection of air bubbles in the shaft of the hair. There is no evidence that hair ever goes white overnight, whether in response to shock, strain or any other cause. Rapid whitening may occur patchily in a matter of days, but it is more often a matter of weeks or months. In the more rapid cases the cause is thought to be a form of ALOPECIA in which the dark hairs which fall out are replaced by white hairs. An alternative cause is VITILIGO. Certain drugs, including mephenesin and CHLOROQUINE, may also cause whitening of the hair.... white hair

White tea is a fruity low-caffeine beverage with a delicate aroma and a sweet or bittersweet taste. Despite its name, it has a pale yellow colour. White tea originated in the Fujian province of China sometime in the 18th century. Green tea and black tea are made from the leaves of the tea plant, whereas white tea is prepared from its white fuzzy buds. White tea is minimally processed, withered in natural sunlight and only slightly oxidized. White Tea Brewing White tea brewing is a quite easy procedure. When preparing white tea, preferably use water heated at a below boiling temperature of approximately 80 degrees Celsius and steep it for three to five minutes. White tea should be enjoyed plain because milk might neutralize its beneficial properties. White Tea Health Benefits White tea consumption offers your body numerous health benefits by boosting the immune system and strengthening its power to fight against viruses and bacteria. The beverage is also effective in the prevention of dental plaque, one of the main causes of tooth decay, and it may also have a beneficial effect for people afflicted with osteoporosis or arthritis. Research shows that some white tea compounds protect against cancer, reduce the cholesterol level and improve artery function, thus lowering the risk of cardiovascular disease. The antioxidants in white tea protect the skin and make it appear healthy and radiant. Regular consumption of white tea may also prevent obesity and aid in the weight-loss process. White tea increases metabolism, encouraging the burning of fat.

Organic acids, containing carbon, hydrogen, and oxygen, that are constituents of fats and oils. There are more than 40 fatty acids, which are found in nature and which are distinguished by their constituent number of carbon and hydrogen atoms.

Certain fatty acids cannot be synthesized by the body and must be provided by the diet. These are linoleic, linolenic, and arachidonic acids, sometimes collectively termed essential fatty acids. Strictly speaking, only linoleic acid is essential, since the body can make the other 2 from linoleic acid obtained from food. (See also nutrition.)... fatty acids

A group of unsaturated fatty acids essential for growth and body function. EFA activity requires three polyunsaturated fatty acids (linolenic, linoleic and arachidonic). The most essential are linoleic and arachidonic which are closely involved in metabolism, transport of fats, and maintenance of cell membranes. While linolenic and arachidonic acids can be synthesised in the body, linoleic cannot.

EFA deficiency may be caused by alcohol, particularly Omega-6. Deficiencies may be responsible for a wide range of symptoms from foul-smelling perspiration to psoriasis, pre-menstrual tension and colic. EFAs are precursors of prostaglandin formation.

EFAs are present in oily fish and reduce the adhesion of platelets and the risk of heart disease. They reduce blood cholesterol and increase HDLs.

Common sources: cold pressed seeds, pulses, nuts and nut oils. Evening Primrose oil (15-20 drops daily). The best known source is Cod Liver oil (1-8 teaspoons daily); (children 1 teaspoon daily to strengthen immune system against infection); bottled oil preferred before capsules. To increase palatability pour oil into honey jar half filled with orange or other fruit juice, shake well and drink from the jar.

Margarines, salad dressings, cooking and other refined vegetable oils inhibit complete absorption of EFAs and should be avoided. EFAs require the presence of adequate supply of Vitamins A, B, C, D, E and minerals Calcium, Iron, Magnesium and Selenium. ... essential fatty acids (efa)

Nutrients that provide the body with its most concentrated form of energy. Fats, which are also called lipids, are compounds containing chains of carbon and hydrogen with very little oxygen. Chemically, fats consist mostly of fatty acids combined with glycerol. They are divided into 2 main groups, saturated and unsaturated, depending on the proportion of hydrogen atoms. If the fatty acids contain the maximum possible quantity of hydrogen, the fats are saturated. If some sites on the carbon chain are unoccupied by hydrogen, they are unsaturated; when many sites are vacant, they are polyunsaturated. Monounsaturated fats are unsaturated fats with only one site that could take an extra hydrogen. Animal fats, such as those in meat and dairy products, are largely saturated, whereas vegetable fats tend to be unsaturated.

Fats are usually solid at room temperature; oils are liquid. The amount and types of fat in the diet have important implications for health. A diet containing a large amount of fat, particularly saturated fat, is linked to an increased risk of atherosclerosis and subsequent heart disease and stroke.

Some dietary fats, mainly triglycerides (combinations of glycerol and 3 fatty acids), are sources of the fat-soluble vitamins A, D, E, and K and of essential fatty acids. Triglycerides are the main form of fat stored in the body. These stores act as an energy reserve and also provide insulation and a protective layer for delicate organs. Phospholipids are structural fats found in cell membranes. Sterols, such as cholesterol, are found in animal and plant tissues; they have a variety of functions, often being converted into hormones or vitamins.

Dietary fats are first emulsified by bile salts before being broken down by lipase, a pancreatic enzyme. They are absorbed via the lymphatic system before entering the bloodstream.Lipids are carried in the blood bound to protein; in this state they are known as lipoproteins. There are 4 classes of lipoprotein: very low-density lipoproteins (VLDLs), low-density lipoproteins (LDLs), high-density lipoproteins (HDLs), and chylomicrons. LDLs and VLDLs contain large amounts of cholesterol, which they carry through the bloodstream and deposit in tissues. HDLs pick up cholesterol and carry it back to the liver for processing and excretion. High levels of LDLs are associated with atherosclerosis, whereas HDLs have a protective effect.

(n-3 fatty acids) polyunsaturated fatty acids with a double bond at the third carbon atom in the chain. Omega-3 fatty acids are essential for brain development and are also associated with many health benefits, including protection against heart disease and possibly stroke and inflammatory conditions. There are three major types: alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA). The main source of EPA and DHA is fish oils. Vegetarians rely on EPA and DHA being synthesized by the body from dietary sources of ALA. See also essential fatty acids.... omega-3 fatty acids

Compare unsaturated fatty acid.... saturated fatty acid

a *fatty acid in which one (monounsaturated) or many (polyunsaturated) of the carbon atoms are linked by double bonds that are easily split in chemical reactions so that other substances can connect to them.

(NAFLD) a spectrum of conditions affecting the liver in the absence of excessive alcohol consumption. NAFLD is a common cause of referral for patients with abnormal liver function tests. Fatty liver is excessive fat accumulation in the liver seen as an area of brightness within the liver on ultrasound examination. Fatty liver does not lead to irreversible liver damage in the majority of cases. Nonalcoholic steatohepatitis (NASH) is inflammation of the liver associated with accumulation of fat. It is often linked to insulin resistance, diabetes, hypertension, obesity, and *metabolic syndrome. Treatment involves dietary modification, regular physical exercise, weight reduction, and management of underlying conditions (e.g. diabetes, hypertension, and hiperlipidaemia). NASH may predispose to *cirrhosis and may ultimately require liver transplantation.... nonalcoholic fatty liver disease

a congenital abnormality of heart conduction caused by the presence of an *accessory pathway of conduction between the atria and ventricles. It results in premature excitation of one ventricle and is characterized by an abnormal wave (delta wave) at the start of the QRS complex on the electrocardiogram. The accessory pathway predisposes the patient to episodes of fast heart rate due to the rapid self-sustaining circulation of an electrical impulse from the atria to the ventricles and back again (*atrioventricular reciprocating tachycardia). Emergency treatment is in the form of drugs that temporarily block the re-entry circuit. Permanent destruction of the accessory pathway by *radiofrequency ablation is usually curative. [L.

Betula alba

FAMILY: Betulaceae

SYNONYMS: B. alba var. pubescens, B. odorata, B. pendula, European white birch, silver birch.

GENERAL DESCRIPTION: Decorative tree, up to 15–20 metres high, with slender branches, silvery-white bark broken into scales, and light green oval leaves. The male catkins are 2–5 cms long, the female up to 15 cms long.

DISTRIBUTION: Native to the northern hemisphere; found throughout Eastern Europe, Russia, Germany, Sweden, Finland, the Baltic coast, northern China and Japan.

OTHER SPECIES: Many cultivars exist of this species of birch. The paper birch (B. papyrifera) and B. verrucosa are also used for the production of birch bud oil and/or birch tar. NB Should not be confused with the oil from the sweet birch (B. lenta) which is potentially toxic.

HERBAL/FOLK TRADITION: Birch buds were formerly used as a tonic in hair preparations. Birch tar is used in Europe for all types of chronic skin complaints: psoriasis, eczema, etc. In Scandinavia the young birch leaflets and twigs are bound into bundles and used in the sauna to tone the skin and promote the circulation. The sap is also tapped in the spring and drunk as a tonic. Buds, leaves and bark are used for ‘rheumatic and arthritic conditions, especially where kidney functions appear to need support … oedematous states; urinary infections and calculi.’.

ACTIONS: Anti-inflammatory, antiseptic, cholagogue, diaphoretic, diuretic, febrifuge, tonic.

EXTRACTION: 1. Essential oil by steam distillation from the leaf-buds. 2. Crude birch tar is extracted by slow destructive distillation from the bark; this is subsequently steam distilled to yield a rectified birch tar oil.

CHARACTERISTICS: 1. Pale yellow, viscous oil with a woody-green balsamic scent. It crystallizes at low temperatures. 2. The crude tar is an almost black, thick oily mass. The rectified oil is a brownish-yellow, clear oily liquid with a smoky, tar-like, ‘Russian leather’ odour. It blends well with other woody and balsamic oils.

PRINCIPAL CONSTITUENTS: 1. Mainly betulenol and other sesquiterpenes. 2. In the tar oil: phenol, cresol, xylenol, guaiacol, creosol, pyrocatechol, pyrobetulin (which gives the ‘leather’ scent).
