摘 要:目的研究怀牛膝(Achyranthes bidentata Blume,BL)水煎剂对2型糖尿病大鼠肝脏胰岛素酶(insulin-degrading enz- yme,IDE)基因mRNA表达的影响。方法 随机选取以不同剂量怀牛膝水煎剂灌胃的2型糖尿病大鼠每组10只,以生理盐水 灌胃的2型糖尿痛大鼠及正常对照组大鼠各10只,用RT-PCR法测定大鼠肝脏胰岛素酶基因mRNA的表达。结果 2型糖 尿病大鼠模型组IDE基因mRNA的表达高于正常组(P<0.05)。怀牛膝治疗组各组IDE基因mRNA的表达均低于2型糖尿病 大鼠模型组(P<0.05),并且与正常对照组相比无显著性差异(P>0.05)。结论 怀牛膝水煎剂通过抑制肝胰岛素酶基因 mRNA的表达。Objective:To study the effect of Achyranthes bidentata Blume (BL) on the expression of the liver insulin- degrading enzyme mRNA in type2 diabetic rats. Methods: Selecting 2 type diabetic rats with taken diverse dosage Achyranthes bidentata Blume (BL) and Physiological saline each ten rats in every group and natural ten rats in random, the expression of liver IDE mRNA was mensurated by RT - PCR. Results: The mRNA expression of liver IDE in 2 type diabetic groups were higher than that of natural group ( P 〈 0.05), and that Achyranthes bidentata Blume (BL) groups were lower than that of type 2 diabetic model (P 〈 0.05). Conclusion: Achyranthes bidentata Blume (BL) can define the mRNA expression of liver IDE in type 2 diabetic rats.
