| VCAM | vascular cell adhesion molecule |
| immune serum | Blood serum containing antibodies. (14 Nov 1997) |
|---|---|
| immune serum globulin | A sterile solution of globulin's that contains many antibodies normally present in adult human blood; a passive immunizing agent frequently used for prophylaxis against hepatitis A. (05 Mar 2000) |
| immune suppression | Suppression of the immune response by some compound or agent. (05 Mar 2000) |
| immune surveillance | <immunology> The hypothesis that lymphocyte traffic ensures that all or nearly all parts of the vertebrate body are surveyed by visiting lymphocytes in order to detect any altered self material, for example mutant cells. (18 Nov 1997) |
| immune system | <immunology> The body system, made up of many organs and cells, that defends the body against infection, disease and foreign substances. The immune system is often stimulated in specific ways to fight cancer cells. (16 Dec 1997) |
| immune thrombocytopenia | Thrombocytopenia associated with antiplatelet antibodies. See: isoimmune neonatal thrombocytopenia, autoimmune neonatal thrombocytopenia. (05 Mar 2000) |
| immune thrombocytopenic purpura | <haematology> A low number of platelets in the blood, which is common in people with HIV, but often resolves as immune deficiency worsens. HIV-related ITP usually does not have serious consequences. Its cause has not been definitely determined. Treatment with AZT frequently alleviates the condition. (09 Oct 1997) |
| immune tolerance | The specific failure of a normally responsive individual to make an immune response to a known antigen. It results from previous contact with the antigen by an immunologically immature individual (foetus or neonate) or by an adult exposed to extreme high-dose or low-dose antigen, or by exposure to radiation, antimetabolites, antilymphocytic serum, etc. (12 Dec 1998) |
| tetanus immune globulin | <protein> A protein antibody to tetanus toxin, given as passive immunity for those lacking any prior tetanus vaccination. (27 Sep 1997) |
| zoster immune globulin | A globulin fraction of pooled plasma from individuals who have recovered from herpes zoster; used prophylactically and therapeutically for varicella. (05 Mar 2000) |
| Abbe test plate | <equipment> A long, wedge-shaped coverslip about 0.20 mm thick at one end and 0.10 to 0.12 mm at the other end coated chemically with a silver film on which are ruled horizontal lines. at each variation in thickness of 0.01 mm there are vertical lines. By means of oblique illumination and by focusing on different portions of the plate, it is possible to determine the optimum coverslip thickness for any objective and also, for microscopes with drawtubes, the tube length for best objective performance. The approximate freedom from spherical and chromatic aberrations can also be estimated. Small isolated bits of silver near the edges of the lines form good objects for the star test (05 Aug 1998) |
| acetone test | A test for ketonuria; the suspected urine is shaken up with a few drops of sodium nitroprusside, and strong ammonia water is then gently poured over the mixture; if acetone is present, a magenta ring forms at the line of contact; tablets containing sodium nitroprusside and alkali are now more commonly used. (05 Mar 2000) |
| achievement test | A standardised test used to measure acquired learning, e.g., competence in a specific subject area such as reading or arithmetic, in contrast to an intelligence test which is a useful index of potential ability or learning. (05 Mar 2000) |
| acidified serum test | Lysis of the patient's red cells in acidified fresh serum, specific for paroxysmal nocturnal haemoglobinuria. Synonym: Ham's test. (05 Mar 2000) |
| acid loading test | <nephrology> This is a test used in the diagnosis of renal tubular acidosis. The patient takes ammonium chloride capsules for 3 days to acidify the blood (lower blood pH). A sample of the urine and the blood is then collected and the results are interpreted. (27 Sep 1997) |
