To clarify the gastric motor function after selective proximal vagotomy (SPV) by electromygoraphy in dogs, I designed the following experimental groups; Group I is the control, untreated dogs; Group II is SPV operated dogs; Group III is selective antral vagotomy (SAV) operated dogs. The gastric electromyogram was taken from fasted food stimulated, and insulin stimulated dogs in each groups, and the recording was begun two weeks after the operation. The results are summarized as follows. 1) There were no significant differences in discharge intervals before and after food and insulin stimulation in all groups. 2) The propagation velocity was delayed markedly in SPV- and SAV-operated dogs compared to the untreated dogs before stimulation. 3) It seemed to be that the delay of propagation velocity at fasting, was more prominent in SAV than in SPV. Therefore, it is suggested that antral branch might play an important role on the gastric motor function.
为通过肌电图明确犬选择性近端迷走神经切断术（SPV）后的胃运动功能，我设计了以下实验组；第一组为对照组，即未治疗的犬；第二组为接受SPV手术的犬；第三组为接受选择性胃窦迷走神经切断术（SAV）的犬。从每组禁食、食物刺激及胰岛素刺激的犬身上获取胃肌电图，记录在术后两周开始。结果总结如下。1）所有组在食物和胰岛素刺激前后的放电间隔无显著差异。2）与未治疗的犬相比，SPV和SAV手术犬在刺激前的传播速度明显延迟。3）似乎禁食时传播速度的延迟在SAV组比在SPV组更显著。因此，提示胃窦分支可能在胃运动功能中起重要作用。
