Abstract
Effects of TG on intestinal smooth muscle were examined using isolated guinea-pig ileum and for the effects on gastric secretion Schild's rats were used. Stimulant actions of TG on guinea-pig ileum may be indirect, that is, the stimulation of postganglionic parasympathetic nerves, leading to the release of acetylcholine. Gastric secretion stimulating action of TG on Schild's rats may be direct action to the oxyntic glands and it may be not mediated by released acetylcholine or histamine.
