| erythrocytic series | The cells in the various stages of development in the red bone marrow leading to the formation of the erythrocyte, e.g., erythroblasts, normoblasts, erythrocytes. (05 Mar 2000) |
|---|---|
| erythrocytoblast | Synonym: erythroblast. Origin: erythro-+ G. Kytos, cell, + blastos, germ (05 Mar 2000) |
| erythrocytolysin | <protein> Bacterial exotoxins that can lyse erythrocytes. (18 Nov 1997) |
| erythrocytolysis | Synonym: haemolysis. Origin: erythrocyte + G. Lysis, loosening (05 Mar 2000) |
| erythrocytometer | An instrument for counting the red blood cells; Hayden used this term to denote an instrument to measure the diameter of red blood cells. Origin: erythrocyte + G. Metron, measure (05 Mar 2000) |
| erythrocytopenia | Deficiency in the number of red blood cells. Synonym: erythrocytopenia. Origin: erythrocyte + G. Penia, poverty (05 Mar 2000) |
| erythrocytopoiesis | <haematology> Process of production of erythrocytes in the marrow in adult mammals. A pluripotent stem cell (CFU) produces, by a series of divisions, committed stem cells (BFU Es) that give rise to CFU Es, cells that will divide only a few more times to produce mature erythrocytes. Each stem cell product can give rise to 2exp11 mature red cells. (18 Nov 1997) |
| erythrocytorrhexis | A partial erythrocytolysis in which particles of protoplasm escape from the red blood cells, which then become crenated and deformed. Synonym: erythrorrhexis. Origin: erythrocyte + G. Rhexis, rupture (05 Mar 2000) |
| erythrocytoschisis | A breaking up of the red blood cells into small particles that morphologically resemble platelets. Origin: erythrocyte + G. Schisis, a splitting (05 Mar 2000) |
| erythrocytosis | <haematology> An abnormal elevation in the number of red blood cells. Normal RBC counts should be in the range of 4.6-6.2 million per cubic millimetre for males and 4.2-5.4 million per cubic millimetre for females. Erythrocytosis may occur for physiologic reasons (to increase oxygen carrying capacity) in those with chronic obstructive pulmonary disease or those who live at higher altitudes. (27 Sep 1997) |
| erythrocyturia | Red blood cells in urine. (05 Mar 2000) |
| erythrodegenerative | Pertaining to or characterised by degeneration of the red blood cells. (05 Mar 2000) |
| erythroderma | A non-specific designation for intense and usually widespread reddening of the skin from dilatation of blood vessels, often preceding, or associated with exfoliation. Synonym: erythrodermatitis. Origin: erythro-+ G. Derma, skin (05 Mar 2000) |
| erythroderma desquamativum | Severe, extensive seborrheic dermatitis with exfoliative dermatitis, generalised lymphoadenopathy, and diarrhoea in the newborn; frequently occurs in undernourished, cachectic children. Synonym: Leiner's disease. (05 Mar 2000) |
| erythroderma exfoliativa | Familial continual skin peeling characterised by a separation of stratum corneum in leaflike flakes occurring everywhere except on the palms and soles; the cause is unknown. Synonym: erythema exfoliativa, erythroderma exfoliativa. (05 Mar 2000) |
