Abstract

The actions of adrenaline, noradrenaline and phenylephrine were studied both on the terminal tract of bile duct (prepared as spiral strips or intact) and on the adjacent duodenum taken from the calf and the cat. These amines contract the terminal bile duct and relax the duodenum. Furthermore, on the basis of the action of some adrenaline antagonists, the hypothesis is advanced that there are alpha-receptors which mediate contraction of muscle in the sphincterial zone of the bile duct.

摘要

研究了肾上腺素、去甲肾上腺素和去氧肾上腺素对小牛和猫的胆管终末段(制备成螺旋条或完整状态)以及相邻十二指肠的作用。这些胺类物质可使胆管终末段收缩,使十二指肠舒张。此外,基于某些肾上腺素拮抗剂的作用,提出了如下假说:存在α受体,其介导胆管括约肌区肌肉的收缩。
