| anaemia, megaloblastic | Anaemia characterised by the presence of megaloblasts in the bone marrow. (12 Dec 1998) |
|---|---|
| anaemia, myelophthisic | Anaemia characterised by appearance of immature myeloid and nucleated erythrocytes in the peripheral blood, resulting from infiltration of the bone marrow by foreign or abnormal tissue. (12 Dec 1998) |
| anaemia, neonatal | The mildest form of erythroblastosis foetalis in which anaemia is the chief manifestation. (12 Dec 1998) |
| anaemia, pernicious | A megaloblastic anaemia occurring in children but more commonly in later life, characterised by histamine-fast achlorhydria, in which the laboratory and clinical manifestations are based on malabsorption of vitamin b 12 due to a failure of the gastric mucosa to secrete adequate and potent intrinsic factor. (12 Dec 1998) |
| anaemia, refractory | Anaemia (a shortage of red blood cells) unresponsive to treatment. (12 Dec 1998) |
| anaemia, refractory, with excess of blasts | Chronic refractory anaemia with granulocytopenia, and/or thrombocytopenia. Myeloblasts and progranulocytes constitute 5 to 40 percent of the nucleated marrow cells. (12 Dec 1998) |
| anaemia, sickle cell | A disease characterised by chronic haemolytic anaemia, episodic painful crises, and pathologic involvement of many organs. It is the clinical expression of homozygosity for haemoglobin s. (12 Dec 1998) |
| anaemia, sideroblastic | Anaemia characterised by the presence of erythroblasts containing excessive deposits of iron in the marrow. (12 Dec 1998) |
| anaemic | Pertaining to or manifesting the various features of anaemia. (05 Mar 2000) |
| anaemic anoxia | A term formerly considered synonymous with anaemic hypoxia, but now reserved for extremely severe cases in which oxygen is almost completely lacking. (05 Mar 2000) |
| anaemic halo | Pale, relatively avascular areas in the skin seen around vascular spiders, cherry angiomas, and sometimes in acute macular eruptions. (05 Mar 2000) |
| anaemic hypoxia | Hypoxia resulting from a decreased concentration of functional haemoglobin or a reduced number of erythrocytes; it is caused by haemorrhage or anaemia of various types, or by poisoning with CO2, nitrites, or chlorates. (05 Mar 2000) |
| anaemic infarct | An infarct in which little or no bleeding into tissue spaces occurs when the blood supply is obstructed. Synonym: pale infarct, white infarct. (05 Mar 2000) |
| anaemic murmur | A nonvalvular murmur heard on auscultation of the heart and large blood vessels in cases of profound anaemia associated mainly with turbulent blood flow due to decreased blood viscosity. (05 Mar 2000) |
| anaerobe | A microorganism that either does not require oxygen or actually cannotlive in the presence of oyxgen. (09 Oct 1997) |
