摘　　要：目的 :研究国产格列美脲 (Gli)对家兔、大鼠血糖及糖耐量水平和胰岛素释放的影响。方法 :以正常Wister大鼠和家兔为实验对象 ,以给药前、后血糖和胰岛素水平的变化为指标 ,观察Gli的降血糖作用。结果 :Gli呈剂量依赖性降低大鼠血糖 ,平均降低23 % ,其效价强度与格列本脲相当 ;糖耐量实验表明 ,Gli呈剂量依赖性地阻遏家兔灌服葡萄糖所致30min和60min血糖的升高 ;时效关系研究显示 ,大鼠给予Gli后30min血糖开始下降 ,3h时已降至坪值 ,大约为给药前的60 % ;该药能明显促进大鼠和家兔的胰岛素释放 ,与给药前相比胰岛素水平平均上升40 %～70 % ,其效价强度约为格列本脲的2倍。结论 :Gli可以通过促进胰岛素的释放而降低血糖 ,其降血糖的效价强度与格列本脲等效 ,且起效更快、更为温和 。AIM:To study the effects of domestic glimepiride(Gli) on blood sugar,glucose tolerance and release of insulin in rabbits and rats METHODS:Taken the changes of blood sugar level and glucose tolerance before and after giving drug as parameters,the hypoglycemic effect of Gli was observed in rabbits and rats RESULTS:Gli dose-dependly decreased the levels of blood glucose in rats with a decrease of 23% in high-dose group and seemed to be similar to glibenclamide in potency of lowering blood sugar Gli increased release of insulin by 40%～70% in rats and rabbits and was twice as potent as glibenclamide;Glucose tolerance test showed that Gli could restrain the rising of blood glucose at 30 min and 60 min after glucose was administrated ig in rabbits Time-response relation displayed that blood glucose began to drop 30 min after Gli 1 0mg/kg administered and the levels of blood glucose dropped by 40% 3 h later CONCLUSION:The domestic Gli has similar effects to glibenclamide on lowering blood sugar However,its effect on lowering blood sugar seems to be quicker,shorter and more moderate than that of glibenclamide
