| erythrogen | <chemistry> Carbon disulphide; so called from certain red compounds which it produces in combination with other substances. A substance reddened by acids, which is supposed to be contained in flowers. A crystalline substance obtained from diseased bile, which becomes blood-red when acted on by nitric acid or ammonia. Origin: Gr. Red + -gen. Source: Websters Dictionary (01 Mar 1998) |

| erythrogenesis imperfecta | Congenital nonregenerative, familial hypoplastic, or pure red cell anaemia; erythrogenesis imperfecta; Diamond-Blackfan syndrome; autosomal recessive normocytic normochromic anaemia resulting from congenital hypoplasia of the bone marrow, which is grossly deficient in erythroid precursors while other elements are normal; anaemia is progressive and severe, but leukocyte and platelet counts are normal or slightly reduced; survival of transfused erythrocytes is normal; minor congenital anomalies are found in some patients. Synonym: congenital nonregenerative anaemia, Diamond-Blackfan anaemia, Diamond-Blackfan syndrome, erythrogenesis imperfecta, familial hypoplastic anaemia, pure red cell anaemia. (05 Mar 2000) |
| erythrogenic | 1. Producing red, as causing an eruption or a red colour sensation. 2. Pertaining to the formation of red blood cells. Origin: erythro-+ -gen, producing (05 Mar 2000) |
| erythrogenic toxin | <protein> Toxin produced by strains of Streptococcus pyogenes responsible for scarlet fever. Three antigenic variants of the toxin are known. It is a small protein that is complexed with hyaluronic acid and can intensify the effects of other toxins such as endotoxin and streptolysin O. (18 Nov 1997) |
| erythrogonium | The precursor of an erythrocyte; occasionally refers to the erythropoietic tissue as a whole. Origin: erythro-+ G. Gone, generation (05 Mar 2000) |
| erythrogranulose | <physiology> A term applied by Brucke to a substance present in small amount in starch granules, coloured red by iodine. Origin: Gr. Red + E. Granulose. Source: Websters Dictionary (01 Mar 1998) |
| erythroid | Of a red colour; reddish; as, the erythroid tunic (the cremaster muscle). Origin: Gr. Red: cf. Gr. Source: Websters Dictionary (01 Mar 1998) |
| erythroid cell | Cell that will give rise to erythrocytes. (18 Nov 1997) |
| erythroid progenitor cells | Committed, erythroid stem cells derived from myeloid stem cells. The progenitor cells develop in two phases: erythroid burst-forming units (bfu-e) followed by erythroid colony-forming units (cfu-e). Bfu-e differentiate into cfu-e on stimulation by erythropoietin, and then further differentiate into erythroblasts when stimulated by other factors. (12 Dec 1998) |
| erythroid transcription factor | <molecular biology> Transcription factor that binds to regulatory regions of genes expressed in erythroid cells. (18 Nov 1997) |
| erythroidin | A nicotinic cholinergic antagonist which unlike most members of this group of agents, is a tertiary amine and hence enters the central nervous system. (05 Mar 2000) |
| erythrokeratoderma variabilis | A dermatosis characterised by hyperkeratotic plaques of bizarre, geographic configuration, associated with erythrodermic areas that may vary remarkably in size, shape, and position from day to day; onset is usually in the first year of life; autosomal dominant inheritance. Synonym: keratosis rubra figurata. (05 Mar 2000) |
| erythrokeratodermia | The association of erythoderma and hyperkeratosis, which may be symptomatic at sites of chronic injury or inherited; ataxia appears later in life; symmetrical progressive erythrokeratoderma is inherited as an autosomal dominant gene and does not involve the palms and soles. Origin: erythro-+ G. Keras, horn, + derma, skin, + -ia, condition (05 Mar 2000) |
| erythrokinetics | A consideration of the kinetics of erythrocytes from their generation to destruction; erythrokinetic studies are sometimes made in cases of anaemia to evaluate the balance between erythrocyte production and destruction. Origin: erythro-+ G. Kinesis, movement (05 Mar 2000) |
| erythrol | Synonym: erythritol. (05 Mar 2000) |
