title: [Effect of dopamine and adrenaline on the motility function of the digestive tract in the plaice Platessa platessa].
abstract: Electrophysiological studies have been made of the inhibitory effects of dopamine and adrenaline on motor activity of the stomach and intestine in the plaice Platessa platessa. This effect revealed itself in suppression of peristaltic and tonic contractions of the digestive tract for 2-5 hours. Inderal did not abolish the inhibitory effect of dopamine. This effect was partially abolished by phentolamine and completely abolished by metoclopramide. The latter did not change the effect of adrenaline on the motor activity of the digestive tract. Catecholamine influences on feeding behaviour in fishes were demonstrated. Possible existence of specific dopamine receptors in structures innervating muscles of the digestive tract is discussed.
