摘　　要：利用复方地芬诺酯建立肠道蠕动抑制模型。通过设置模型组、阳性组、空白组、刺梨汁低、中、高剂量组,对造模成功的小鼠连续灌胃15 d,并测定小肠的运动;同时对大鼠进行灌胃28 d后,评定体重增重、摄食量、饲料利用率、胃蛋白酶活性和胃蛋白排出量以研究刺梨汁不同剂量促消化功能的效果。结果表明,与模型组相比,刺梨汁中、高剂量组小鼠小肠推进率提高了45.83%、51.35%(P<0.05);与正常组相比,刺梨低、中、高剂量组对大鼠体重增重和饲料利用率没有显著性差异(P>0.05),但摄食量增加了1.39%、2.64%、4.25%(P<0.05),刺梨中、高剂量组大鼠胃蛋白酶活性增强了41.38%、33.41%,胃蛋白酶排出量提高了38.19%、32.53%(P<0.05、P<0.01)。由此表明,刺梨汁具备促消化作用。The inhibition model of intesinal perisalsis was established by compound dipheoxylate.The model group,the positive group,the blank group,and the low,medium,and high dose Rose roxburghii Tratt juice group were tested.And the mice with the successful model were given continuous gavage for 15 days with the small intestine motion was measured.Moreover,after 28 days of administration,the following indicators were tested including weight gain,food intake,feed utilization,pepsin activity and gastric protein excretion to explore the effect of different doses of Rose roxburghii Tratt juice on promoting digestive function.The results showed that compared with the model group,the small intestine propulsion rate of the mice in the medium and high dose Rose roxburghii Tratt juice group was increased by 45.83%and 51.35%(P<0.05)respectively.Meanwhile,compared with the normal group,there was no significant difference in weight gain and feed utilization in the low,medium and high dose R.roxburghii Tratt group(P>0.05).But the food intake increased by 1.39%,2.64%and 4.25%(P<0.05).Furthermore,the pepsin activity of the rats in the medium and high dose R.roxburghii Tratt group increased by 41.38%and 33.41%,and the pepsin excretion increased by 38.19%and 32.53%(P<0.05 and P<0.01)respectively.This indicates that R.roxburghii Tratt juice had an effect on digestion.
