摘要
目的观察灯盏花素对2型糖尿病大鼠周围神经病变的防治作用。方法将Wistar大鼠随机分为对照组(10只)、模型组,对照组正常规饮食,模型组用高糖高脂饮食加小剂量链脲佐菌素(STZ)注射诱导2型糖尿病,然后把成模大鼠分为2组:糖尿病组、治疗组各14只。治疗组给予灯盏花素10mg.kg-1.d-1。分别于用药后1、3个月测定血脂、血糖,坐骨神经运动传导速度,并观察腓肠神经病理改变。结果治疗组大鼠血脂、血糖较糖尿病组明显降低,坐骨神经运动传导速度较糖尿病组明显提高(P<0.05或P<0.01),腓肠神经有髓神经纤维数量和纤维总截面积增加,较糖尿病组亦明显加大(P<0.05P<0.01)。结论灯盏花素对实验性2型糖尿病大鼠周围神经损害有一定防治作用。
Objective To study the effect of Breviscapine on peripheral neuropathy in type 2 diabetes melli- tus rats. Methods The rat models of type 2 diabetes mellitus were induced by feeding high-sugar and high-fat diet, with low-dose streptozotocin (STZ) intraperitoneal injection (30 mg/kg), Then the model rats were divided into two groups: diabetes mellitus group, treatment group (the rats were fed with Breviscapine 10mg·kg^-1·d^-1). After 1,3 month of administration, the plasma glucose, plasma fat, electrophysioloyic changes and the pathological development of sutal nerve were observed. Results In treatment group, plasma g[ucose and plasma fat were significantly lower than those of diabetes mellitus group,however,the motor conduction velocity of sciatic nerve was significantly increased, as compared with that of diabetes mellitus group ( P 〈 0.05 or P 〈 0.01).The pathological changes in treatment group was lighter than those of diabetes mellitus group ( P 〈 0.05 or P 〈 0.01). Conclusion Breviscapine has certain preventive and therapeutic effect on peripheral netu'opathy in rats with type 2 diabetes mellitus.
