胰多肽(PP)是近年发现的一种消化道激素。它可以影响消化液(胃液、胰液等)的分泌。本实验室曾发现BPF对大鼠急性胰腺炎有保护作用。本工作试图探讨BPP对大鼠实验性十二指肠溃疡是否有保护作用。 实验用雌性大白鼠,体重150～165克。分为3组:A,对照组,10只,腹腔注射生理盐水;B,小剂量组,5只,腹腔注射BPP1μg/0.2ml;C,大剂量组,8只,腹腔注 Pancreatic polypeptide (PP) is a digestive hormone discovered in recent years. It can affect the secretion of digestive juices (gastric juice, pancreatic juice, etc.). The laboratory has found that BPF has protective effects on acute pancreatitis in rats. This work attempts to investigate whether BPP has protective effects on experimental duodenal ulcer in rats. Experimental female rats, weighing 150-165 grams. Divided into 3 groups: A, control group, 10, intraperitoneal injection of saline; B, low-dose group, 5, intraperitoneal injection of BPP 1 μg/0.2 ml; C, high-dose group, 8 animals, intraperitoneal injection
