有关胃电的报导多见于狗、猫、兔等动物,而对大鼠则较少研究。我们观察了大鼠胃窦部、幽门括约肌及十二指肠球部的肌电活动,结果如下。 实验用正常大鼠15只,予先经手术将铂丝双电极分别埋藏在胃窦部、十二指肠球部(各距幽门括约肌1厘米)及幽门括约肌肌层上。电极引线由皮下行进至背部肩胛骨间引出供记录用。伤口愈合后(7-10天)用日本产RM-6000型多道记录仪同时记录出 Gastrointestinal reports more common in dogs, cats, rabbits and other animals, while less research in rats. We observed the myoelectric activity of the rat antral pylorus, pyloric sphincter and duodenal bulb, the results are as follows. Fifteen normal rats were used in the experiment, and the platinum double electrodes were buried in the antrum, the duodenal bulb (1 cm each from the pyloric sphincter) and the pyloric sphincter by surgery. Electrode leads from the skin to the back of the scapula to draw for recording purposes. Wound healing (7-10 days) with Japan made RM-6000 multi-channel recorder simultaneously recorded
