Abstract:
OBJECTIVE:To investigate the effects of Yiqi huayu granules on gastrointestinal motility of gastrointestinal motili-ty disorder model mice and blood rheology of acute blood stasis model rats,and to provide experimental evidence for clinical use of it. METHODS:50 ICR mice were randomly divided into normal group,model group,mosapride group(positive control chemi-cal drug,0.003 g/kg),Muxiang shunqi pills group(positive control TCM,0.36 g/kg)and Yiqi huayu granules group(2.4 g/kg), with 10 mice in each group. Treatment groups were given relevant medicine solution intragastrically,once a day,for a week;nor-mal group and model group were given normal saline intragastrically. Those groups fasted for 24 h after last medication,and then were given above medicine intragastrically;1 h later,they were given atropine sulfate intragastrically to induce gastrointestinal mo-tility disorder model except for normal control group. The stomach residue rate and intestinal propulsive rate of mice were mea-sured. 60 SD rats were randomly divided into normal group,model group,Compound danshen tablet group(positive control,1.0 g/kg)and Yiqi huayu granules high-dose,medium-dose and low-dose groups(2.4,1.2,0.6 g/kg),with 10 rats in each group. Nor-mal group and model group were given normal saline intragastrically,and treatment groups were given relevant medicine,once a day,for a week. 1 h after last medication,those groups were given adrenaline intraperitoneally+aqua astricta. to induce acute blood stasis model except for normal group. The whole blood viscosity(high-shearing,middle-shearing,low-shearing),plasma viscosity, 1,3,5 min platelet aggregation rate ,hematocrit and maximal platelet aggregation rate were all detected in rats. RESULTS:Com-pared with normal group,stomach residue rate of mice in model group was increased significantly(P<0.01),while intestinal pro-pulsive rate was decreased significantly(P<0.01). The whole blood viscosity(high-shearing,middle-shearing,low-shearing),plas-ma viscosity,hematocrit,1,3,5 min platelet aggregation rate and maximal platelet aggregation rate of rats were all increased sig-nificantly in model group (P<0.01). Compared with model group,above indexes of mice/rats were all improved significantly in treatment groups(P<0.05 or P<0.01). CONCLUSIONS:Yiqi huayu granules can significantly promote the function of gastrointes-tinal peristalsis and anticoagulation.
