Alterations in the pattern of basic electric rhythm of the stomach and jejunum were studied in a total of 12 dogs subjected to following procedures; (a) transection and close contact repair of the entire seromuscular layer in the upper jejunum; (b) transection and close contact repair of the seromuscular layer in the stomach; (c) transection and interposition repair with alpha cyano acrylate in the stomach. Jejunal transection has resulted in permanent interruption in coupling of the basic electrical rhythm irrespective of repair procedures of the muscle layers. Gastric transection has revealed interruption in coupling of the basic electrical rhythm temporarily, but coupling phenomenon was observed in about 14 days. Gastrin transection with alpha cyano acrylate interposition has resulted in interruption in coupling of the basic electrical rhythm when the animal is maintained in fasting state. However, coupling has occurred immediately after the feeding or intragastric balloon distension. These results indicate that there exists some difference between the stomach and the jejunum in the effects of transection on electrical activities. Coupling phenomenon of the basic electrical rhythm observed in the transected stomach is probably due to an interaction of nervous system or a mechanical stimulus acting across the transection line.
对总共12只接受了以下手术的狗的胃和空肠基本电节律模式的改变进行了研究：(a) 上半段空肠全层浆肌层横断并紧密对合修复；(b) 胃浆肌层横断并紧密对合修复；(c) 胃横断并用α-氰基丙烯酸酯进行插入修复。空肠横断导致基本电节律的耦合永久性中断，而与肌层的修复方式无关。胃横断暂时显示基本电节律的耦合中断，但在约14天后观察到耦合现象。用α-氰基丙烯酸酯插入进行胃横断在动物处于禁食状态时导致基本电节律的耦合中断。然而，在喂食或胃内气囊扩张后立即出现了耦合。这些结果表明，横断对电活动的影响在胃和空肠之间存在一些差异。在横断的胃中观察到的基本电节律耦合现象可能是由于神经系统的相互作用或跨越横断线的机械刺激。
