摘要
【目的】观察竹叶石膏汤对实验性2型糖尿病模型大鼠降糖降脂及抗氧化作用。【方法】采用高脂饮食结合小剂量链脲佐菌素复制实验性2型糖尿病大鼠模型。将60只大鼠随机分为正常对照组,模型对照组,竹叶石膏汤低、中、高剂量组(剂量分别为3.6、7.2、14.4 g·kg^(-1)·d^(-1)),二甲双胍组(0.15 g·kg^(-1)·d^(-1)),每组10只。以空腹血糖、尿糖、糖化血红蛋白、总胆固醇(TC)、甘油三酯(TG)、高密度脂蛋白胆固醇(HDL-C)、低密度脂蛋白胆固醇(LDL-C)、血清胰岛素、血清超氧化物歧化酶(SOD)、丙二醛(MDA)为主要指标,观察竹叶石膏汤对糖尿病大鼠血糖、血脂及氧化应激反应的影响。【结果】与模型组比较,竹叶石膏汤可不同程度降低大鼠空腹血糖、尿糖,及糖化血红蛋白、TC、TG、MDA水平(P<0.05),升高SOD活力和血清胰岛素水平(P<0.05),且呈一定的量效关系。【结论】竹叶石膏汤对糖尿病有较好的降糖降脂及抗氧化作用。
Objective To observe the hypoglycemic, hypolipidemic and antioxidant effects of Zhuye Shigao Decoction（ZSD）on experimental type 2 diabetes mellitus rats. Methods Type 2 diabetes mellitus rat model was induced by intragastric administration of high fat diet（10 mL/kg）and intraperitoneal administration of streptozotocin（30 mg·kg^（-1））. Sixty male Sprague-Dawley rats were randomized into normal group, model group, low-,moderate-and high-dose ZSD groups（in the dosage of 3.6,7.2,14.4 g·kg^（-1）·d^（-1） respectively）,and Metformin group（0.15 g·kg^（-1）·d^（-1））, 10 rats in each group. With fasting blood glucose, urine glucose, glycosylated hemoglobin, total cholesterol（TC）,triglyceride（TG）,high-density lipoprotein cholesterol（HDL-C）,lowdensity lipoprotein cholesterol（LDL-C）,serum insulin,serum superoxide dismutase（SOD）and malondialdehyde（MDA） as the main indexes,we evaluated the influence of ZSD on the blood glucose and lipid levels as well as oxidative stress in type 2 diabetes mellitus rats. Results Compared with the model group, the levels of blood glucose,urine glucose and glycosylated hemoglobin, and the contents of TC,TG,MDA were decreased（P 〈0.05）,whereas SOD activity and serum insulin level were obviously increased（P〈 0.05） in ZSD groups. ZSD showed dose-related effectiveness in the treatment of diabetic rats. Conclusion ZSD has certain hypoglycemic,hypolipidemic and antioxidant effects in treating type 2 diabetes mellitus.
