| erythroblast | <haematology> Rather noncommittal name for a nucleated cell of the bone marrow that gives rise to erythrocytes. See: normoblasts, BFU E, CFU E, primitive and definitive erythroblasts (18 Nov 1997) |
|---|---|
| erythroblastemia | The presence of nucleated red cells in the peripheral blood. Origin: erythroblast + G. Haima, blood (05 Mar 2000) |
| erythroblastic anaemia | Anaemia characterised by the presence of large numbers of nucleated red cells (normoblasts and erythroblasts) in the peripheral blood. Seen especially in newborns with haemolytic anaemia, such as that caused by Rh or ABO incompatibility. Synonym: erythroblastic anaemia. (05 Mar 2000) |
| erythroblastopenia | A primary deficiency of erythroblasts in bone marrow, seen in aplastic anaemia. Origin: erythroblast + G. Penia, poverty (05 Mar 2000) |
| erythroblastosis | The presence of erythroblasts in considerable number in the blood. Origin: erythroblast + -osis, condition (05 Mar 2000) |
| erythroblastosis foetalis | <haematology> A condition which develops in the foetus due to an incompatibility between the mother's blood type (RH factor) and the baby's. Maternal antibodies, which enter the foetal circulation during delivery attack the baby's red blood cells leading to haemolysis (rupture of the cells). Symptoms include an infant with an enlarged liver and spleen, swelling, jaundice and anaemia. (27 Sep 1997) |
| erythroblastosis virus, avian | A species of avian type c retroviruses (retroviruses type c, avian) causing progressive anaemia and weakness in domestic and wild fowl. (12 Dec 1998) |
| erythroblastosis, foetal | Haemolytic anaemia of the foetus or newborn infant, caused by the transplacental transmission of maternally formed antibody, usually secondary to an incompatibility between the blood group of the mother and that of her offspring. (12 Dec 1998) |
| erythroblastotic | Pertaining to erythroblastosis, especially erythroblastosis foetalis. (05 Mar 2000) |
| erythroblasts | Immature, nucleated erythrocytes occupying the stage of erythropoiesis that follows formation of erythroid progenitor cells and precedes formation of reticulocytes. Popularly called normoblasts. (12 Dec 1998) |
| erythrocatalysis | Phagocytosis of the red blood cells. Origin: erythro-+ G. Katalysis, dissolution (05 Mar 2000) |
| erythrocebus | A genus of old world monkeys of the family cercopithecinae that inhabit the forests and savannas of africa. It contains only one species, erythrocebus patas, also known as the patas monkey or red monkey. (12 Dec 1998) |
| erythrocebus patas | A species of the genus erythrocebus, subfamily cercopithecinae, family cercopithecidae. It inhabits the flat open arid country of africa. It is also known as the patas monkey or the red monkey. (12 Dec 1998) |
| erythrochroic | <zoology> Having, or subject to, erythrochroism. Source: Websters Dictionary (01 Mar 1998) |
| erythrochroism | <ornithology> An unusual redness, especially. In the plumage of birds, or hair of mammals, independently of age, sex, or season. Origin: Gr. Red + colour. Source: Websters Dictionary (01 Mar 1998) |
