| bacterial capsules | An envelope of loose gel surrounding a bacterial cell which is associated with the virulence of pathogenic bacteria. Some capsules have a well-defined border, whereas others form a slime layer that trails off into the medium. most capsules consist of relatively simple polysaccharides but there are some bacteria whose capsules are made of polypeptides.

| brood capsules | Small hollow projections from the lining membrane of a hydatid cyst from which the scoleces arise. (05 Mar 2000) |
| capsules | Hard or soft, soluble containers of a suitable substance, for enclosing a dose of medicine, usually for oral administration. (12 Dec 1998) |
| congenital severe combined immunodeficiency | Disease, one form of which is caused by the lack of a transcription factor required for expression of HLA class II genes. (18 Nov 1997) |
| severe combined immunodeficiency | Group of rare congenital disorders characterised by impairment of both humoral and cell-mediated immunity, leukopenia, and low or absent antibody levels. It is inherited as an x-linked or autosomal recessive defect. About half of the patients with autosomal recessive scid are deficient in the enzyme adenosine deaminase. (12 Dec 1998) |
| severe combined immunodeficient mice | Mice that lack both T and B lymphocytes and are used for transplantation and study of human lymphoid tissues resulting in a SCID-human mouse chimera. See: severe combined immunodeficiency. (05 Mar 2000) |
| severe postanoxic encephalopathy | Coma that develops a few days to 3 weeks after an acute hypoxic insult; the latter was usually severe enough to cause an initial bout of coma, which cleared, and was followed by a transient interval of apparent normality. Synonym: severe postanoxic encephalopathy. (05 Mar 2000) |
| active congestion | Congestion due to an increased flow of arterial blood to a part. (05 Mar 2000) |
| brain congestion | Increased volume of the intravascular compartment of the brain; often associated with brain swelling. Synonym: encephalaemia. (05 Mar 2000) |
| venous congestion | <physiology> Overfilling and distention of the veins with blood as a result of mechanical obstruction or right ventricular failure. (05 Mar 2000) |
| passive congestion | Congestion caused by obstruction or slowing of the venous drainage, resulting in partial stagnation of blood in the capillaries and venules. (05 Mar 2000) |
| physiologic congestion | Hyperaemia occurring during functional activity of an organ. Synonym: physiologic congestion. (05 Mar 2000) |
| congestion | Excessive or abnormal accumulation of blood in a part. Origin: L. Congestio, from congerere = to heap together (18 Nov 1997) |
| hypostatic congestion | Congestion due to pooling of venous blood in a dependent part. Synonym: hypostasis. (05 Mar 2000) |
| functional congestion | Hyperaemia occurring during functional activity of an organ. Synonym: physiologic congestion. (05 Mar 2000) |
