| irreversible | Incapable of being reversed. (18 Nov 1997) |
|---|---|
| irreversible colloid | A colloid that is not again soluble in water after having been dried at ordinary temperature. Synonym: unstable colloid. (05 Mar 2000) |
| irreversible hydrocolloid | A hydrocolloid whose physical state is changed by an irreversible chemical reaction when water is added to a powder and an insoluble substance is formed. (05 Mar 2000) |
| irreversible process | <chemistry> Any real process, when a system undergoes the changes State 1 - greater than State 2 - greater than State 1 by any real pathway, the universe is different that before the cyclic process took place in the system. (09 Jan 1998) |
| irreversible reaction | A reaction or response by the tissues to a pathogenic agent characterised by a permanent pathologic change. (05 Mar 2000) |
| irreversible shock | Shock that has progressed beyond the stage when it will respond to transfusion or other form of treatment, and recovery is impossible. (05 Mar 2000) |
| allogeneic inhibition | Inhibition or injury to allogeneic cells that occurs when lymphocytes are mixed and cultured with other cells of different genotypes in vitro. (05 Mar 2000) |
| macrophage inhibition factor | <cytokine> A group of lymphokines (including a 14 kD glycoprotein) produced by activated T lymphocytes that reduces macrophage mobility and probably increases macrophage macrophage adhesion. (18 Nov 1997) |
| macrophage migration inhibition test | A test which measures the presence of migration-inhibitory factor. Usually peritoneal macrophages are placed in a capillary tube in the presence or absence of supernatants from activated T-cells. If MIF is present, the migration of monocyte/macrophages is reduced. Synonym: macrophage migration inhibition test, migration inhibition test. (05 Mar 2000) |
| reactive inhibition | Tendency toward a lessened strength of response due to practice or activity. It is independent of the effect of reward and is a direct function of time interval since the last response and the number of preceding responses. (12 Dec 1998) |
| reciprocal inhibition | Contraction in a muscle is accompanied by a loss of tone or by relaxation in the antagonistic muscle. Synonym: reciprocal inhibition. (05 Mar 2000) |
| reflex inhibition | A situation in which sensory stimuli decrease reflex activity. (05 Mar 2000) |
| cell migration inhibition | Phenomenon of cell-mediated immunity measured by in vitro inhibition of the migration or phagocytosis of antigen-stimulated leukocytes or macrophages. Specific assays have been developed to estimate levels of migration-inhibitory factor, immune reactivity against tumour-associated antigens, and immunosuppressive effects of infectious microorganisms. (12 Dec 1998) |
| central inhibition | <physiology> Suppression or diminution of outgoing impulses from a reflex centre. (05 Mar 2000) |
| residual inhibition | The inhibition or suppression of tinnitus by use of a sound-generating device (residual inhibitor) which masks the sounds of tinnitus and produces a residual sound-inhibiting effect when the device is turned off. (05 Mar 2000) |
