Abstract

The removal of the proximal 1/3 part of the intestine led to reduction of "spontaneous" inhibition of gastric secretion caused by gastrocepin provoking selective blockade of gastric M-cholinoreceptors in rats with gastric fistulae. The enteral mechanisms regulating gastric secretion, seem to participate in this inhibition and gastric M-cholinoreceptors seem to change their function under the influence of enterogastric activity.

摘要

切除大鼠近端1/3肠段可导致胃泌素引起的“自发性”胃分泌抑制作用减弱,胃泌素可选择性阻断胃瘘大鼠的胃M胆碱能受体。调节胃分泌的肠内机制似乎参与了这种抑制作用,并且胃M胆碱能受体在肠胃活动的影响下似乎会改变其功能。
