| pyruvate kinase deficiency | A disorder in which there is a deficiency of pyruvate kinase in red blood cells; characterised by haemolytic anaemia varying in degree from one patient to another; autosomal recessive inheritance. (05 Mar 2000) |
|---|---|
| hypoxanthine guanine phosphoribosyltransferase deficiency | A sex-linked inherited metabolic disorder; complete deficiency results in Lesch-Nyhan syndrome; incomplete deficiency is associated with acute gouty arthritis and renal stones. (05 Mar 2000) |
| steroid sulfatase deficiency | A form of ichthyosis, due to 3-beta-hydroxysteroidsulfate sulfatase deficiency, that appears at birth or in early infancy and affects males; characterised by scaling predominantly on the neck and trunk but not on the palms and soles; histologically, there is hyperkeratosis, a granular layer in the epidermis, and normal epidermal cell turnover. Synonym: steroid sulfatase deficiency. (05 Mar 2000) |
| niacin deficiency | <biochemistry> A niacin deficiency disease (pellagra) caused by improper diet and characterised by skin lesions, gastrointestinal disturbances and nervousness. Depression, dermatitis, dementia and diarrhoea are common symptoms. (27 Sep 1997) |
| normal human plasma | Sterile plasma obtained by pooling approximately equal amounts of the liquid portion of citrated whole blood from eight or more adult humans who have been certified as free from any disease which is tranmissible by transfusion, and treating it with ultraviolet irradiation to destroy possible bacterial and viral contaminants. (05 Mar 2000) |
| normal human serum | Sterile serum obtained by pooling approximately equal amounts of the liquid portion of coagulated whole blood from eight or more persons who are free from any disease transmissible by transfusion. (05 Mar 2000) |
| normal human serum albumin | A sterile preparation of serum albumin obtained by fractionating blood plasma proteins from healthy persons; used as a transfusion material and to treat oedema due to hypoproteinaemia. Synonym: dried human albumin. (05 Mar 2000) |
| novel human deoxyribonuclease | <enzyme> 45% identical to dnase i. Registry number: EC 3.1.- Synonym: nhdnase (26 Jun 1999) |
| debrancher deficiency | Type of glycogen storage disease, due to deficiency of amylo-1,4-1,6-transglucosidase (brancher enzyme). Synonym: brancher deficiency glycogenosis, debrancher deficiency. (05 Mar 2000) |
| deficiency | A lack or defect. (18 Nov 1997) |
| deficiency, alpha-1 antitrypsin | An inherited disease with little or no production of an important protein, alpha-1 antitrypsin. The lack of this protein leads to damage of various organs, mainly the lung and liver. The disease may become apparent at a very early age or in adulthood, as shortness of breath or liver-related symptoms (jaundice, fatigue, fluid in the abdomen, mental changes, or gastrointestinal bleeding). There are several options for treatment of the lung disease, including replacement of the missing protein. Treatment of the liver disease is a well-timed liver transplant (12 Dec 1998) |
| deficiency anaemia | Any anaemia resulting from a dietary deficiency of materials essential to red blood cell formation, e.g., iron, vitamins (especially folic acid), protein. Synonym: deficiency anaemia. (05 Mar 2000) |
| deficiency, calcium | A low blood calcium (hypocalcaemia). Hypocalcaemia makes the nervous system highly irritable with tetany (spasms of the hands and feet, muscle cramps, abdominal cramps, overly active reflexes, etc.). Chronic calcium deficiency contributes to poor mineralization of bones, soft bones (osteomalacia) and osteoporosis; and, in children, rickets and impaired growth. Food sources of calcium include dairy foods, some leafy green vegetables such as broccoli and collards, canned salmon, clams, oysters, calcium-fortified foods, and tofu. According to the National Academy of Sciences, adequate intake of calcium is 1 gram daily for both men and women. The upper limit for calcium intake is 2.5 grams daily. (12 Dec 1998) |
| deficiency dermatitis and diarrhoea, zinc | A genetic disease called acrodermatitis enteropathica is characterised by the simultaneous occurrence of skin inflammation (dermatitis) and diarrhoea. The skin on the cheeks, elbows and knees and tissue about the mouth and anus are inflammed. There is also balding of the scalp, eyebrows and lashes, delayed wound healing and recurrent bacterial and fungal infections due to immune deficiency. The key laboratory finding is an abnormally low blood zinc level reflecting impaired zinc uptake. Oral treatment with zinc is curative. (12 Dec 1998) |
| deficiency disease | Any disease resulting from undernutrition or an inadequacy of calories, proteins, essential amino acids, fatty acids, vitamins, or trace minerals. (05 Mar 2000) |
