| CDE blood group | See Rh blood group, Blood Groups appendix. (05 Mar 2000) |
| p blood-group system | A blood group related to the abo, lewis and I systems. at least five different erythrocyte antigens are possible, some very rare, others almost universal. Multiple alleles are involved in this blood group. (12 Dec 1998) |
| pectoral group of axillary lymph nodes | Lymph nodes located along the lateral thoracic vein; they receive the drainage of the pectoral region, including most of the drainage of the breast. Synonym: nodi lymphatici axillaris pectorales, anterior group of axillary lymph nodes. (05 Mar 2000) |
| central group of axillary lymph nodes | Nodes located around the midportion of the axillary vein; they receive afferent vessels from the lateral (brachial), pectoral, and subscapular groups of axillary nodes and send efferent vessels to the apical group of axillary node's. (05 Mar 2000) |
| peer group | Group composed of associates of same species, approximately the same age, and usually of similar rank or social status. (12 Dec 1998) |
| glycosyl group | <biochemistry> A radical chemical group on a larger molecule, derived from a sugar or starch molecule, which is attached to the rest of the larger molecule by way of a glycosidic bond. (09 Oct 1997) |
| C group viruses | A serologic group of the genus Bunyavirus (formerly called group C arboviruses), composed of 12 species including Caraparu, Murutucu, and Oriboca virus. (05 Mar 2000) |
| characterizing group | A group of atoms in a molecule that distinguishes the class of substances in which it occurs from all other classes; thus carbonyl (CO) is the characterizing group of ketones; COOH, of organic acids, etc. (05 Mar 2000) |
| r group | <chemistry> A chemical abbreviation that normally denotes an alkyl group, but is occasionally used to refer to other organic groups. (09 Oct 1997) |
| Rhesus blood group | <haematology> Human blood group system with allelic red cell antigens C, D and E. The D antigen is the strongest. Red cells from a Rhesus positive foetus cross the placenta and can sensitise a Rehesus negative mother, expecially at parturition. The mother's antibody may then, in a subsequent pregnancy, cause haemolytic disease of the newborn if the foetus is Rhesus positive. The disease can be prevented by giving antiD IgG during the first 72 hours after parturition to mop up D red cells in the maternal circulation. 1st ed (18 Nov 1997) |
| rh-hr blood-group system | Erythrocyte isoantigens of the rh (rhesus) blood group system, the most complex of all human blood groups, because the genes differ by determining a different number of the over thirty antigens thus far described and do so with remarkably different quality. The major antigen rh or d is the most common cause of erythroblastosis foetalis. (12 Dec 1998) |
| chlorine group | The halogens. (05 Mar 2000) |
| group | 1. A cluster, crowd, or throng; an assemblage, either of persons or things, collected without any regular form or arrangement; as, a group of men or of trees; a group of isles. 2. An assemblage of objects in a certain order or relation, or having some resemblance or common characteristic; as, groups of strata. 3. <biology> A variously limited assemblage of animals or planta, having some resemblance, or common characteristics in form or structure. The term has different uses, and may be made to include certain species of a genus, or a whole genus, or certain genera, or even several orders. 4. A number of eighth, sixteenth, etc, notes joined at the stems; sometimes rather indefinitely applied to any ornament made up of a few short notes. Origin: F groupe, It. Gruppo, groppo, cluster, bunch, packet, group; of G. Origin: cf. G. Krepf craw, crop, tumour, bunch. See Crop. Source: Websters Dictionary (01 Mar 1998) |
| group agglutination | Agglutination by antibodies specific for minor (group) antigens common to several microorganisms, each of which possesses its own major specific antigen. Synonym: cross agglutination. (05 Mar 2000) |
