It has been reported that interdigestive motor activities occur in the gallbladder and sphincter of Oddi as well as in the gastroduodenal tract and truncal vagus nerves modulate the gastroduodenal motility pattern. In the present study, the vagal branches which influence on the interdigestive motor activity of these organs were determined in conscious dogs. In the normal dog, interdigestive motor activities closely related to interdigestive migrating motor complex (IMC) in the gastric antrum and descending duodenum were recorded in the gallbladder and sphincter of Oddi. In dogs whose celiac branches of the vagus nerve were chronically resected, cycle periods of interdigestive motor activity in the stomach, duodenum, gallbladder and sphincter of Oddi significantly prolonged as compared with those in the normal dog but the interrelation of them persisted. Quiescent period in motility prolonged and the active period shortened. Resection of the pyloric branches had no influence on the interdigestive motor activities in all organs. The results imply that celiac branches of the vagus nerve modulate the interdigestive motor activity in the stomach, descending duodenum, gallbladder and sphincter of Oddi.
据报道，消化间期运动活动发生在胆囊和Oddi括约肌，以及胃十二指肠 tract 中，并且迷走神经干调节胃十二指肠的运动模式。在本研究中，在清醒犬中确定了影响这些器官消化间期运动活动的迷走神经分支。在正常犬中，与胃窦和十二指肠降部的消化间期移行运动复合波（IMC）密切相关的消化间期运动活动在胆囊和Oddi括约肌中被记录到。在迷走神经腹腔支被长期切除的犬中，与正常犬相比，胃、十二指肠、胆囊和Oddi括约肌的消化间期运动活动的周期显著延长，但它们之间的相互关系仍然存在。运动的静止期延长，活动期缩短。切除幽门支对所有器官的消化间期运动活动没有影响。结果表明，迷走神经腹腔支调节胃、十二指肠降部、胆囊和Oddi括约肌的消化间期运动活动。
