| reversible | Capable of going through a series of changes in either direction, forward or backward, as a reversible chemical reaction. (18 Nov 1997) |
|---|---|
| reversible calcinosis | A form of calcinosis sometimes observed in patients who constantly ingest large quantities of milk and alkaline medicines, as in the treatment of peptic ulcer. (05 Mar 2000) |
| reversible colloid | A colloid that is again soluble in water after having been dried at ordinary temperature. Synonym: stable colloid. (05 Mar 2000) |
| reversible decortication | A temporary loss of function of the cerebral cortex. (05 Mar 2000) |
| reversible hydrocolloid | A hydrocolloid composed of a base substance whose physical state may be changed to that of a liquid by the application of heat and then changed to that of an elastic gel by cooling. (05 Mar 2000) |
| reversible hydrogenase | <enzyme> Isolated from heterocysts and vegetative cells of anabena Registry number: EC 1.12.- (26 Jun 1999) |
| reversible process | <chemistry> A cyclic process carried out by a hypothetical pathway, which leaves the universe exactly the same as it was before the process, no real process is reversible. For chemical systems we consider a process at equilibrium to be reversible. Examples are phase transitions that occur at the melting point or boiling point temperatures at 1 atm pressure. (09 Jan 1998) |
| reversible reaction | A chemical reaction that takes place in either direction i.e., from the forward or reverse direction; ionization is such a reaction, as are reaction's involving racemases, isomerases, mutases, transferases, etc. (05 Mar 2000) |
| reversible shock | Shock that will respond to treatment and from which recovery is possible. (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) |
