RESUMO
Objective To observe the effect of Yun-Pi Prescription in different dose on small intestinal function of splenic asthenia rats, so as to explore mechanisms of Yun-pi Prescription in treatment of children apositia. Methods Experimental rats were randomly divided in to six groups:the control group, the model group, the positive control group (Xiao shi Jian er Syrup group), Yun-Pi Prescription in high, middle and low dose group. Measure the changes of body weight and food intake, observe excretory rate of D-xylose of rats. Results Yun-Pi Prescription could increase body weight and food intake, improve excretory rate of D-xylose in splenic asthenia rats. Conclusion Yun-Pi Prescription could improve the small intestinal absorptive function of splenic asthenia rats with dose-effect relationship.
