| major histocompatabilty complex | <immunology> A cluster of genes on chromosome 6 concerned with antigen production and critical to transplantation. The MHC includes the human leukocyte antigen (HLA) genes. (12 Dec 1998) |
| major histocompatibility complex | The set of gene loci specifying major histocompatibility antigens, for example HLA in man, H 2 in mice, RLA in rabbits, RT 1 in rats, DLA in dogs, SLA in pigs, etc. Acronym: MHC (18 Nov 1997) |
| VATER complex | A constellation of vertebral defects, anal atresia, tracheoesophageal fistula with oesophageal atresia, and renal and radial anomalies; associated with Fanconi's anaemia. (05 Mar 2000) |
| rancke complex | <radiology> Combination of: calcified peripheral nodule (Ghon lesion), calcified hilar nodes, occurs in 50% of patients with primary TB (12 Dec 1998) |
| ventricular complex | The continuous QRST waves of each beat in the electrocardiogram. (05 Mar 2000) |
| receptor-CD3 complex, antigen, T-cell | Molecule composed of the non-covalent association of the T-cell antigen receptor (receptors, antigen, T-cell) with the CD3 complex (antigens, CD3). This association is required for the surface expression and function of both components. The molecule consists of up to seven chains: either the alpha/beta or gamma/delta chains of the T-cell receptor, and four or five chains in the CD3 complex. (12 Dec 1998) |
| Ghon's complex | Calcification seen in pulmonary parenchyma (usually mid-lung area) and hilar nodes resulting from earlier, usually childhood, infection with tuberculosis. Synonym: Ghon's complex, Ghon's focus, Ghon's primary lesion. (05 Mar 2000) |
| castration complex | A child's fear of injury to the genitals by the parent of the same sex as punishment for unconcious guilt over oedipal feelings, fantasied loss of the penis by a female or fear of its actual loss by a male, unconscious fear of injury from those in authority.

| vitamin b complex | <chemical> A group of water-soluble substances including thiamine, riboflavin, niacin (nicotinic acid), niacinamide (nicotinamide), the vitamin b6 group (including pyridoxine, pyridoxal, pyridoxamine), biotin, pantothenic acid, folic acid, possibly para-aminobenzoic acid, inositol, vitamin b12, and possibly choline. Chemical name: Vitamin B (12 Dec 1998) |
| central complex | In an enzyme-catalyzed reaction, the structural complex of the enzyme and all of the enzyme's substrates (or the enzyme with all of the enzyme's products) equivalent to the binary complex for a one-substrate enzyme. Compare: binary complex, Michaelis complex. (05 Mar 2000) |
| glycine cleavage complex | A complex of several proteins that catalyze the reversible reaction of glycine with tetrahydrofolate to produce CO2, NH3, and N5,N10-methylenetetrahydrofolate; a deficiency of this enzyme (or one of its subunits) will result in nonketotic hyperglycinaemia. Synonym: glycine synthase. (05 Mar 2000) |
| Golgi complex | <cell biology> Intracellular stack of membrane bounded vesicles in which glycosylation and packaging of secreted proteins takes place. Part of the GERL complex. Synonym: Golgi body, Golgi vesicles, dictyosome (in plants), parabasal body (in flagellate protozoa). (11 Jan 1998) |
