Glucose

Glucose, also known as dextrose or grape sugar, is the form of sugar found in honey and in grapes and some other fruits. It is also the form of sugar circulating in the bloodstream, and the form into which all sugars and starches are converted in the small INTESTINE before being absorbed. Glucose is a yellowish-white crystalline substance soluble in water and having the property of turning a ray of polarised light to the right. It is often given to patients orally or, sometimes, intravenously as an easily assimilated form of CARBOHYDRATE. It has the further practical advantage in this context of not being nearly as sweet-tasting as cane sugar and therefore relatively large amounts can be consumed without sickening the patient.... glucose

Glucose-tolerance Test

A way of assessing the body’s e?ciency at metabolising GLUCOSE. The test is used in the diagnosis of DIABETES MELLITUS. The patient is starved for up to 16 hours, after which he or she is fed glucose by mouth. The concentrations of glucose in the blood and urine are then measured at half-hour intervals over a period of two hours.... glucose-tolerance test

Alpha-antitrypsin Deficiency

A rare genetic disorder in which a person is missing the enzyme alpha1-antitrypsin, which protects the body from damage by other enzymes.

The disease mainly affects tissues in the lungs, resulting in emphysema, and the liver, causing cirrhosis.

The effects of alpha1-antitrypsin deficiency may not become apparent until after the age of 30.

There is no cure, but symptoms can be relieved by drug treatment.

In severe cases, a liver transplant may be a possibility.... alpha-antitrypsin deficiency

Glucose-6-phosphate Dehydrogenase

An ENZYME that performs an essential function in the metabolism of CARBOHYDRATE. A de?ciency in this enzyme – acronym G6PD – results in the breakdown of ERYTHROCYTES (HAEMOLYSIS), usually in the presence of oxidants (see OXIDANT) such as infections or drugs. The de?ciency disorder is a hereditary condition in which the enzyme is absent. The condition, characterised by pallor, rigors and pain in the loin, is divided into African, European (including FAVISM) and Oriental types. Sufferers should avoid substances that trigger haemolysis. Acute episodes are best treated symptomatically.... glucose-6-phosphate dehydrogenase

Anaemia: Iron Deficiency

An estimated 15 per cent of the female population suffers from this form of anaemia. A deficiency of nutritional iron is responsible for oxygen starvation of the blood due to insufficient haemoglobin. Number of red cells is reduced.

Aetiology: heavy menstrual loss, feeble constitution from hereditary weakness, poor diet, hidden or known blood loss from gastric ulcer, pregnancy, bleeding piles or insufficient food minerals: iron, copper, calcium, etc, chronic liver or kidney disease, worms, anorexia nervosa, rheumatoid arthritis, tuberculosis. Symptoms. Tiredness, dizziness, breathlessness, palpitations, pale face and mucous membranes. White of eyes may be blue. Enlarged flabby tongue often bears impression of teeth marks. Hair lifeless, fingernails brittle and ridged. There may be angina, tinnitus and general reduced efficiency.

Treatment. The object is to achieve absorption of iron to raise normal haemoglobin levels and increase red cells. Echinacea has a reputation for regeneration of red cells. Herbs used with success: Echinacea, Gentian, Motherwort, Mugwort, Barberry, Hops, Nettles, Saw Palmetto, Chaparral, Red Clover, Dandelion.

Bitter herbs stimulate absorption of vital nutrients from the stomach, toning liver and pancreas, increasing the appetite; usually given half hour before meals. See: BITTERS.

Gentian. 1 teaspoon fine-cut chips to 2 cups cold water steeped 8 hours (overnight). Dose: Half-1 cup thrice daily before meals.

Tea. Formula. Combine: Agrimony 1; Barberry bark 1; Nettles 2; White Poplar bark half. Place 1oz (30g) in 1 pint (500ml) cold water and bring to boil. Simmer 10 minutes. Drink cold: Half-1 cup thrice daily, before meals.

Powders. Formula. Echinacea 2; Gentian 1; Kelp 1; pinch Red Pepper. Dose: 500mg (two 00 capsules or one-third teaspoon) thrice daily, before meals.

Liquid extracts. Formula: Echinacea 1; Queen’s Delight 1; Ginseng 1; Ginger quarter. Dose: 30-60 drops in water, thrice daily, before meals.

Infusion Gentian Co Conc BP (1949). Dose: 30-60 drops.

Diet. Dandelion coffee, as desired. Molasses. Desiccated liver.

Floradix. A pre-digested iron preparation. Readily assimilable by the body. Compounded by Dr Otto Greither (Salus Haus). Iron is fed onto yeast which breaks down the metal and absorbs its cells. Other tonic ingredients include extracts of nettles, carrots, spinach, fennel, Vitamin C plus supplements;

Angelica root, Mallow, Horsetail, Yarrow, Juniper and Rosehips. Not chemically preserved.

Avoid chocolate, egg yolk, tea, coffee, wheat bran.

Supplements. Daily. Vitamin C (1g morning and evening). Vitamin B12, Folic acid 400mcg. Vitamin C is the most potent enhancer of iron absorption. Multivitamin containing iron.

Note: Iron absorption is decreased by antacids, tetracyclines, phosphates, phytates (phytic acid from excessive intake of wholewheat bread), and excessive calcium supplements. Lack of stomach hydrochloric acid impairs iron absorption, especially in the elderly. ... anaemia: iron deficiency

Lactase Deficiency

A condition in which there is an absence of lactase, an enzyme that breaks down lactose (milk sugar), in the cells of the small intestine.

Lactase deficiency results in a reduced ability to digest lactose, also known as lactose intolerance.

The condition may be permanent, or may occur temporarily after gastroenteritis, particularly in young children.

Symptoms include abdominal cramps, bloating, flatulence, and diarrhoea, all of which are caused by the laxative effect of the undigested sugar in the intestines.

Treatment is with a lactose-free diet.... lactase deficiency

Bile Secretion Deficiency

Bile is a greenish-yellow alkaline substance secreted by the liver which emulsifies fat and prevents putrefaction in the intestines. An aid to pancreatic juices.

Alternatives. To stimulate flow, Boldo, Horsetail, Dandelion, Blue Flag root, Milk Thistle, Bogbean, Burdock. Teas, capsules, tablets, Liquid extracts, or Tinctures.

A. Vogel recommends: Barberry, Centuary, St John’s Wort, Sarsaparilla.

Combination tea. Equal parts: Peppermint leaves, Milk Thistle, Dandelion root. 1 teaspoon to each cup boiling water; infuse 15 minutes, 1 cup thrice daily for limited period (1 month).

Bile in the urine. (Bilviria)

Arthur Barker: Liquid Extract Black root 1oz (30ml). Liquid Extract Cornsilk 1oz (30ml). Essential Peppermint 30 drops (2ml). Water to 8oz (240ml). 2 teaspoons in water 3 times daily before meals.

Diet. Dandelion coffee. Artichokes.

See: CHOLAGOGUES. CHOLERETICS. ... bile secretion deficiency

Anaemia, Iron-deficiency

The most common form of anaemia caused by a deficiency of iron, an essential constituent of haemoglobin. The main cause of iron-deficiency anaemia is iron loss due to heavy or persistent bleeding; the most common cause in women of childbearing age is menstruation. Other causes include blood loss from the digestive tract due to disorders such as erosive gastritis, peptic ulcer, stomach cancer, inflammatory bowel disease, haemorrhoids, and bowel tumours (see colon, cancer of). Prolonged use of aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs) can cause gastrointestinal bleeding. In some countries, hookworm infestation of the digestive tract is an important cause of anaemia. Rarely, bleeding may also occur as a result of disorders of the urinary tract (such as kidney tumours or bladder tumours).

Iron deficiency may also be caused or worsened by lack of iron in, or its poor absorption from, the diet.

The symptoms are those of the underlying cause, along with a sore mouth or tongue, and those common to all forms of anaemia, such as fatigue and breathlessness. The diagnosis is made from blood tests and tests to look for an underlying cause. Treatment is given for the cause, along with a course of iron tablets or, very rarely, injections.... anaemia, iron-deficiency

Colour Vision Deficiency

Any abnormality in colour vision that causes difficulty distinguishing between certain colours. Total absence of colour vision (monochromatism) is rare. The most common types of colour vision deficiency are reduced discrimination of red and green. Most cases of red and green colour vision deficiency are caused by defects in the light-sensitive cells in the retina. These defects are usually inherited, although occasionally defects are caused by retinal or optic nerve diseases or injury. The inherited defects tend to be sex-linked (see genetic disorders), which means that the majority of sufferers are male. A person with a severe green deficiency has difficulty distinguishing oranges, greens, browns, and pale reds. In severe red deficiency, all reds appear dull. A much rarer deficiency in which blue cannot be distinguished may be inherited or may be due to degeneration of the retina or optic nerve.... colour vision deficiency

Adenosine Deaminase Deficiency

(ADA deficiency) a genetic disorder affecting about one baby in 25,000 and characterized by a defect in adenosine deaminase (ADA), an enzyme that is involved in purine metabolism. Deficiency of this enzyme results in selective damage to the antibody-producing lymphocytes; this in turn leads to a condition known as *severe combined immune deficiency (SCID), in which the affected baby has no resistance to infection and must be entirely isolated from birth. Such children have only about a 50% chance of surviving for six months. See also gene therapy.... adenosine deaminase deficiency

It is due to reduced numbers of T and B *lymphocytes – white blood cells necessary for fighting infection. Some cases are caused by *adenosine deaminase deficiency. The only treatment currently available is a bone-marrow transplant, but *gene therapy offers hope for the future.... severe combined immune deficiency

Glucose-6-phosphate Dehydrogenase Deficiency

a hereditary disorder – an X-linked condition (see sex-linked) – in which the absence of the enzyme glucose-6-phosphate dehydrogenase (G6PD), which functions in carbohydrate metabolism, results in the breakdown of the red blood cells (*haemolysis), usually after exposure to *oxidants, such as drugs, or infections. The breakdown causes acute attacks that are characterized by pallor, loin pain, and rigors. There are several varieties of G6PD deficiency, which is most common in people of African, Middle Eastern, and Mediterranean descent. Treatment involves identifying and avoiding agents that trigger the haemolysis and treating acute attacks symptomatically. See also favism.... glucose-6-phosphate dehydrogenase deficiency
