| immunologic capping | The process by which lymphoid cell surface immunoglobulin receptors, when exposed to bivalent anti-ig antibodies, collect in patches and form a cap at one pole of the cell. The caps may then be endocytosed or shed into the environment in the form of antigen-antibody complexes. Capping has also been induced by lectins and antigens. (12 Dec 1998) |
|---|---|
| immunologic deficiency syndromes | Syndromes in which there is a deficiency or defect in the mechanisms of immunity, either cellular or humoral. (12 Dec 1998) |
| immunologic diseases | Disorders caused by abnormal or absent immunologic mechanisms, whether humoral, cell-mediated or both. (12 Dec 1998) |
| immunologic factors | Biologically active substances whose activities affect or play a role in the functioning of the immune system. (12 Dec 1998) |
| immunologic memory | <immunology> The ability to rapidly produce large quantities of specific immune cells after subsequent exposure to a previously encountered antigen. (09 Oct 1997) |
| immunologic pregnancy test | A general term for test's for detection of increased human chorionic gonadotropin in plasma or urine by immunologic techniques including latex particle agglutination, haemagglutination inhibition, radioimmunoassay, and radioreceptor assays. (05 Mar 2000) |
| immunologic surveillance | The theory that T-cells monitor cell surfaces and detect structural changes in the plasma membrane and/or surface antigens of virally or neoplastically transformed cells. (12 Dec 1998) |
| immunologic tests | Diagnostic techniques involving the demonstration or measurement of an immune response, including antibody production or assay, antigen-antibody reactions, serologic cross-reactivity, delayed hypersensitivity reactions, or heterogenetic responses. (12 Dec 1998) |
| acoustic tolerance | The maximum sound pressure level that can be experienced without producing pain or permanent defect of hearing in a normal individual. (05 Mar 2000) |
| bile acid tolerance test | A sensitive test of hepatic dysfunction; following oral administration of labelled or unlabelled bile acid, the measured fractional disappearance rate or 10-minute retention is measured. (05 Mar 2000) |
| galactose tolerance test | A liver function test, based on the ability of the liver to convert galactose to glycogen, measured by the rate of excretion of galactose following ingestion or intravenous injection of a known amount; normally, less than 3 g appear in the urine within 5 hours after the ingestion of 40 g. (05 Mar 2000) |
| radiation tolerance | The ability of some cells or tissues to withstand ionizing radiation without serious injury. Tolerance depends on the species, cell type, and physical and chemical variables, including radiation-protective agents and radiation-sensitizing agents. (12 Dec 1998) |
| pain tolerance | The greatest intensity of painful stimulation that an individual is able to tolerate. (05 Mar 2000) |
| gamma-tolerance | The tolerance of a person or a piece of equipment to forces that develop as a result of acceleration or deceleration. (05 Mar 2000) |
| vibration tolerance | The maximum vibratory or oscillatory movements that an individual can experience and bear without pain; the limit of tolerance is a function of amplitude and frequency of the vibration and varies with the direction of application. (05 Mar 2000) |
