영문 초록

The author studied the actions of autonomic drugs on the uterine muscle isolated from Ditrema temmincki Bleeker, and the results obtained were summerized as follows. 1) The motility of the fish uterus was stimulated by epinephrine, norepinephrine and phenylephrine, but inhibited by isoproterenol. 2) The inhibitory effects of isoproterenol on the fish uterus was not affected by phenoxybenzamine, but blocked by propranolol. 3) The excitatory effects of phenylephrine on the fish uterus were blocked by phenoxybenzamine, but stimulated by propranolol. 4) The excitatory effects of epinephrine and norepinephrine were reversed by phenoxybenzamine and stimulated by propranolol. 5) The motility of the fish uterus pretreated with phenoxybenzamine and propranolol was not affected by isoproterenol, phenylephrine, epinephrine and norepinephrine. 6) It seemed that the uterine muscle of the fish had both alpha excitatory and beta inhibitory receptors. 7) The motility of the uterus of the fish was stimulated by acetylcholine. The stimulating action of acetylcholine was antagonized by atropine. 8) The motility of fish uterus was not affected by nicotine and DMPP. The actions of these drugs were not affected by pretreatment with hexamethonium and atropine. 9) It is, therefore, concluded that there are not present ganglia cells furnished with cholinergic fiber in the uterine wall of the fish.
