Desamino-cholecystokinin-octapeptide (CCK-7) increased the gall-bladder pressure and decreased the gastric pressure following i.v. infusion in conscious dogs. In small intestine and Heidenhain pouch CCK-7 exerted an initial excitatory effect followed by an inhibitory effect on intraluminal pressure and peristalsis. In all organs the effect of CCK-7 on pressure was correlated with a change of spike discharge. CCK-7 is more potent on gastrointestinal motor activity than a Boots preparation of pancreozymin. The results suggest that CCK-7 at doses within the physiological range could be involved in the regulation of gastrointestinal motility.
去氨基胆囊收缩素八肽(CCK - 7)静脉注射给清醒犬后,可升高胆囊压力并降低胃内压力。在小肠和海登海因小胃中,CCK - 7最初产生兴奋作用,随后对腔内压力和蠕动产生抑制作用。在所有器官中,CCK - 7对压力的影响与锋电位发放的变化相关。CCK - 7对胃肠运动活性的作用比一种胰酶泌素的布茨制剂更强。结果表明,生理范围内剂量的CCK - 7可能参与胃肠动力的调节。
