| 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 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) |
