摘要
目的:阐明通降颗粒治疗大鼠实验性反流性食道炎(RE)的疗效及作用机制。方法:首先分别采用贲门成形+幽门结扎+胃空肠Roux-en-Y吻合术、贲门钢圈置入固定术建立大鼠实验性食管炎模型,再分别给予不同剂量的通降颗粒及对照药普瑞博思灌胃治疗后,观察食管组织学病理改变及测定胃酸、胃蛋白酶活性、血浆胃动素水平。结果:造模成功后经给药治疗显示两种造模方式均表明通降颗粒浸膏(大剂量组)与模型组的食管黏膜组织病理积分比较有显著差异,且优于西药对照组。通降颗粒可降低RE大鼠的胃酸水平、提高血浆胃动素水平。结论:通降颗粒浸膏可能通过改变胃酸、胃动素水平,促进胃排空三方面机制治疗大鼠实验性RE。
Objective： To study the mechanism of Tongiiang granule on treating GERD. Method： The rats in the model group received steel wire ring-cardiamyopexy. A steel wire ring was fixed firmly on cardia. The rats in the control group tmderwent the cardia-plasty plus pylori ligation plus stomach-empty intestine Roux-en-Y anastomosis. The rats were divided into six groups after operations at random, which were fed up respectively with Tongjiang granule of different dosage and perpulsid. No treatment groups were taken as control. Result： The experiment showed that Tongjiang granule could lighten or cure RE in the pathology, decrease the hydrochloric acid in gastric juice, in the meantime, increase the motilin in the animal blood. This study indicated that the effect of Tongjiang granule group from experimental research was better than that of the control group （perpulsid）. Conclusion： The effects of Tongjiang granule on treating GERD can be achieved by decreasing the hydrochloric acid in gastric juice, increasing the motilin in blood and promoting the gastric impetus in the animal experiment.
