Experimental Study on Dual-Direction Regulation of Tongxie Yaofang on Gastrointestinal Movement of Mice / 中国中医药信息杂志

ABSTRACT

Objective To investigate the dual-direction regulation of Tongxie Yaofang on gastrointestinal movement by studying its effect on gastrointestinal movement of mice in various functional states. Methods Adopting diarrhea model induced by rhubarb,constipation model by compound diphenoxylate and normal mice,the effect of different doses of Tongxie Yaofang on loose stool quantity,degree,diameter,diarrhea rate,loose stool incidence rate,loose stool grade,diarrhea index of every group were observed. By esta blishing hyperfunction of small intestinal function in mice by neostigimine,inhibition of small intestinal function in mice by atropine sulfate and small intestinal propellant function in normal mice,the effect of Tongxie Yaofang on intestinal movement of mice were studied. Results Tongxie Yaofang could inhibit gastrointestinal movement of diarrhea model and hyperfunction of small intestinal function in mice by neostigimine. It could promote gastrointestinal movement of constipation model and inhibit small intestinal function in mice by atropine sulfate. But it had no obvious action on natural mice and its intestinal movement. Conclusions Tongxie Yaofang has dual-direction regulation on gastrointestinal movement of mice in various functional states,which has a good agreement with formula-syndrome in traditional Chinese medicine,conforms to treatment based on syndrome differentiation.
