摘要 目的构建糖尿病动物模型,观察糖脉康对糖尿病大鼠坐骨神经传导速度、肾脏醛糖还原酶(AR)活性的影响。方法40日龄左右的雄性Wistar大鼠30只,随机取10只作为正常对照组给予常规饲料。其余20只大鼠给予高糖高脂饲料喂养4周,左下腹腔注射30mg/kg链脲佐菌素。72h后取尾静脉血测血糖,血糖≥16.7mmol/L表示造模成功。20只糖尿病大鼠随机分为糖尿病组、糖脉康组。糖脉康组给予糖脉康100mg/kg(1mL/100g)灌胃,糖尿病组和正常对照组仅给予等量蒸馏水(1mL/100g)灌胃,共16周。10%水合氯醛麻醉后取大鼠坐骨神经测定神经传导速度,取肾脏测定AR活性。对数据结果进行统计学分析。结果与对照组相比,糖尿病组、糖脉康组血糖明显升高(P<0.01),但糖脉康组血糖与糖尿病组相比没有明显降低(P>0.05);与对照组相比,糖尿病组肾脏皮质AR活性明显升高(P<0.01),糖脉康组AR活性较糖尿病组明显降低(P<0.01);与对照组相比,糖尿病组、糖脉康组坐骨神经传导速度明显降低(P<0.01),糖脉康组神经传导速度较糖尿病组明显升高(P<0.01)。结论糖尿病大鼠肾脏AR活性升高,糖脉康干预可使其AR活性降低,坐骨神经传导速度改善。
