酸化十二指肠引起胆囊收缩的机制,仍是一个悬而未决的问题。我们采用制备有Jones胆囊插管,Thomas胰瘘和胃瘘的狗,从受体阻断剂、迷走神经以及肠粘膜感受器等角度,探讨了这一问题。结果发现,在基础情况下,胆囊压力稳定,基础压为95.5± Acidification of the duodenum causes gallbladder contraction mechanism remains an open question. We used dogs prepared with Jones gallbladder cannula, Thomas pancreatic fistula and gastric fistula to explore this issue from the perspective of receptor blockers, vagus nerve and gut mucosal receptors. The results showed that under the basic conditions, the gallbladder pressure was stable, the basic pressure was 95.5 ±
