| miostagmin reaction | A physiochemical immunity test, designed by Ascoli, consisting in determination of the surface tension of an immune serum to which its specific antigen has been added, before and after incubation at 37캜 for 2 hours; in a positive reaction the surface tension, as measured by the stalagmometer, is lowered.

| miotic | 1. <ophthalmology> Pertaining to, characterised by or producing miosis: contraction of the pupil. 2. <pharmacology> An agent that causes the pupil to contract. 3. <cell biology> Meiotic: characterised by cell division. (18 Nov 1997) |
| miotics | Agents causing contraction of the pupil of the eye. Because the size of the pupil is under the antagonistic control of the sympathetic and parasympathetic systems, drugs affecting either system can cause miosis. Drugs that mimic or potentiate the parasympathetic input to the circular constrictor muscle and drugs that inhibit sympathetic input to the radial dilator muscle tend to contract the pupils. Some sources use the term miotics only for the parasympathomimetic but any drug used to induce miosis is included here. (12 Dec 1998) |
