三清降糖方对实验性2型糖尿病大鼠血糖和血脂的影响

目的:研究三清降糖方对2型糖尿病大鼠血糖和血脂的影响。方法:雄性Wistar大鼠82只,随机选出10只做为正常对照组(C组),其余72只大鼠高糖高脂饮食喂养4周后,以小剂量链脲佐菌素2次ip的方法诱发大鼠2型糖尿病模型,以空腹血糖为依据,采用区组随机的方法,分为三清高、中、低剂量组(SG,SZ,SD组)、模型对照组(M组)、阿卡波糖组(A组)、罗格列酮组(L组)6组,三清高、中、低剂量组按8.05,4.03,1.61 g·kg-1分别ig三清降糖方水提物,M组ig生理盐水,A组、L组分别ig等效剂量的阿卡波糖和罗格列酮,共4周,分别在ig前、ig后2周、4周测空腹血糖及餐后2 h血糖,ig 4周后主动脉采血测血脂、肝肾功能,观察比较各组间血糖血脂的变化。结果:①ig 4周后,SD组空腹血糖水平为(5.0±3.2)mmol·L-1与M组可见统计学显著差异(P<0.05);②ig 4周后,SD组餐后2 h血糖水平为(9.8±3.3)mmol·L-1与SG,M,A,L组可见统计学显著差异(P<0.05);③ig后4周,各组间高密度脂蛋白(HDL-c),低密度脂蛋白(LDL-c),丙氨酸转氨酶(ALT),天冬氨酸转氨酶(AST),肌酐(Cr)水平未见统计学显著差异,SZ组、SD组、M组总胆固醇(CHO)甘油三酯(TG)水平低于C组,有统计学显著差异(P<0.05),但与模型组比较无统计学意义。C组与其他组的血尿素氮(BUN)水平比较可见统计学显著差异(P<0.05),但各给药组与模型组比无显著差异。结论:三清降糖复方低剂量应用有较好的降低空腹血糖和餐后2 h血糖效果。

Effects of Three-clearing Hypoglycemic Formula on Blood Glucose and Blood Lipid in Experimental Rats with Type 2 Diabetes

Objective:To investigate the effect of the Three-clearing Hypoglycemic Formula(Sanqing Jiangtang Fang) on the blood glucose and blood lipids in type 2 diabetic rats.Method:Ten rats were selected randomly from 82 male Wistar rats to form the normal group(group C).With high fat forage diet of four weeks,the rest 72 rats were injected of small dose of streptozotocin(STZ) intraperitioneally twice to establish rats model with type 2 diabetes.Based on fasting blood sugar levels,the model rats were randomly divide...
