小檗碱对2型糖尿病ICR小鼠模型的治疗作用

目的比较小檗碱及小檗碱与添加剂对2型糖尿病ICR小鼠模型的降糖、降脂效果。方法100只三周龄雄性ICR小鼠随机分为正常组、模型组、小檗碱组、小檗碱加低剂量添加剂组、小檗碱加高剂量添加剂组及二甲双胍组,以高糖高脂加尿链佐菌素诱导小鼠2型糖尿病模型,并分别以小檗碱、小檗碱加低剂量添加剂、小檗碱加高剂量每天灌胃干预治疗6周。检测血糖、血清血脂、肾功指标的变化情况;给药前后做糖耐量胰岛素耐量实验。每周量小鼠体重,动态观察小鼠体重变化。代谢笼中测量小鼠饮食水量变化。结果模型组血糖较普食组显著上升(P0.01),且维持较好;血脂指标CHO、HDL-c、LDL-c均较普食组升高(P0.05);其他各检测生化指标差异不显著。小檗碱组空腹血糖较模型组总体下降趋势明显且维持较好(P0.01);血脂较模型组有降低;糖耐量胰岛素耐量较模型组有改善。二甲双胍组血糖较模型组有下降趋势,血脂较模型组无显著差别。小檗碱加低剂量添加剂组较模型组血糖血脂无显著差别。小檗碱加高剂量添加剂组血糖较模型有下降趋势,血脂较模型组有下降趋势,其他各项生化指标均无差别。结论小檗碱降糖效果优于二甲双胍,小檗碱加低剂量添加剂,小檗碱加高添加剂。

Therapeutic Effect of Berberine Recipe on ICR Mouse Model of Type 2 Diabetes

Objective To compare the effect of berberine and additive on serum glucose and lipid level.MethodsType 2 diabetic model was induced by both high lipid food and low dose of streptozotocin(STZ) in mice.The number of 100 three month's mice were randomly divided into normal group,type 2 diabetic model group,berberine treated group,berberine and low dose additive treated group,berberine and high dose additive treated group and metformin treated group.Every group were administered through intragastric administrat...
