黄芩正气胶囊对湿阻中焦证大鼠模型胃肠功能的影响

目的探讨黄芩正气胶囊治疗湿阻中焦证的作用机理。方法复制大鼠湿阻中焦证模型,以0.175,0.350和0.700g/kg剂量灌胃黄芩正气胶囊,观察黄芩正气胶囊对湿阻中焦证模型大鼠血清中胃泌素水平、小肠对D-木糖的吸收率、小肠运动、胃黏膜保护因子超氧化物歧化酶(SOD)和过氧化氢酶(CAT)的活性以及胃病理形态学的影响。结果黄芩正气胶囊能使模型大鼠血清中胃泌素水平明显升高,小肠对D-木糖的吸收率明显提高,小肠运动与SOD、CAT的活性明显增强,胃病理形态改变得到明显改善(P<0.05～0.01)。结论增强胃肠消化、吸收、运动机能和胃黏膜抗氧化能力以及胃抗病变能力,可能是黄芩正气胶囊治疗湿阻中焦证的机制之一。

Effect of Huangqin Zhengqi Capsule on Gastrointestinal Function in Rats with Syndrome of Damp Retention in Middle - jiao

Objective To explore the therapeutic mechanism of Huangqin Zhengqi Capsule(HZC)for the syndrome of damp retention in middle-jiao.Methods The rat model of damp retention in middle-jiao was established according to the literature.HZC was administered by gastric gavage in the dosage of 0.175,0.350 and 0.700 g/kg.After treatment,the serum gastrin content,small intestinal absorbency to D-xylose,small intestinal peristalsis,activities of gastric mucosal protective factors such as superoxide dismutase (SOD) and catalase(CAT)as well as gastric pathologic changes were observed.Results HZC can obviously increase serum gastrin content,increase small intestinal absorbency to D-xylose and peristalsis of small intestine,increase the activities of SOD and CAT,as well as improve the gastric pathologic changes in model rats(P < 0.05 or P < 0.01).Conclusion The one of mechanisms of HZC on the syndrome of damp retention in middle-jiao may be improving gastrointestinal digestive,absorptive and kinetic function,increasing the ability of gastric mucosal antioxidation and preventing stomach from pathological changes.
