EGG-1A型胃电图仪在我国问世后,对胃溃疡、胃炎、胃癌等疾病的胃电活动进行了不少研究,已总结出一些规律,但在动物模型上尚无研究。本文旨在制造大白鼠实验性胃溃疡及急性胃粘膜损伤模型,观察胃电图的变化。1 实验方法及结果1.1 大鼠形成利血平性胃溃疡时的胃电变化取大鼠18只,不拘雌雄,体重193～278g。饥饿(断食不断水)24小时后,随机分为两组,每组9只,一组腹腔注射
After the advent of the EGG-1A electrogastrogram in China, many studies have been conducted on the gastric electrophysiological activities of gastric ulcers, gastritis, and gastric cancer, and some rules have been summarized. However, there are no studies on animal models. This article aims to create rat experimental gastric ulcer and acute gastric mucosal injury model, observe the changes of electrogastrogram. 1 Experimental methods and results 1.1 Gastric electrical changes during the formation of reserpine-induced gastric ulcer in rats Eighteen rats were randomly selected, weighing 193-278 g. After 24 hours of hunger (sweet water), they were randomly divided into two groups, 9 in each group, and one group of intraperitoneal injections.
