The relationship between the food restriction and the formation of experimental 8astric ulcer / 中国病理生理杂志

ABSTRACT

On the basis of Shay's ulcer model, we have studied the effects of food re. striction time on the experimental gastric ulcer in rats. The results indicat that each restricted group forms gastric ulcer after ligation of pylorus 18 hr. There are a postive correlation between the restricted time and the severity of gastric ulcer, and a negative correlation between the severity of gastric ulcer and the amount of gastric acid secretion. We suggested that Shay's ulcer model does not belong to peptic ulcer, but belonges to one of the stress ulcers. The restricted time may play an important role in the mechanism for this ulcer model.
