| anaemia, aplastic | A form of anaemia in which the bone marrow fails to produce adequate numbers of peripheral blood elements. (12 Dec 1998) |
| aplastic | <pathology> Lacking in cell production, as in aplastic anaemia. Origin: Gr. Plassein = to form (27 Sep 1997) |
| aplastic anaemia | <haematology> This form of anaemia occurs when the bone marrow ceases sufficient red and white blood cell production. It may be induced by exposures to high levels of toxic chemicals, radiation and certain drugs. It is generally unresponsive to specific therapy, often accompanied by granulocytopenia and thrombocytopenia, in which the bone marrow may not necessarily be hypocellular or hypoplastic but fails to produce adequate numbers of peripheral blood elements. The term actually is all inclusive and most probably encompasses several clinical syndromes. Origin: Gr. Haima = blood (29 Sep 1997) |
| aplastic lymph | Lymph containing a relatively large number of leukocytes, but comparatively little fibrinogen; such lymph does not form a good clot and manifests only a slight tendency to become organised. Synonym: corpuscular lymph. (05 Mar 2000) |
| congenital aplastic anaemia | <haematology> A rare inherited type of aplastic anaemia which carries an increased risk to the patient of developing leukaemia. May be treated by bone marrow transplant. Origin: Gr. Haima = blood (13 Nov 1997) |

| constitutional hepatic dysfunction | Mild jaundice due to increased amounts of unconjugated bilirubin in the plasma without evidence of liver damage, biliary obstruction, or haemolysis; thought to be due to an inborn error of metabolism in which the excretion of bilirubin by the liver is defective, ascribed to decreased conjugation of bilirubin as a glucuronide or impaired uptake of hepatic bilirubin. Synonym: benign familial icterus, constitutional hepatic dysfunction, Gilbert's disease, Gilbert's syndrome, Hebra's disease. (05 Mar 2000) |
