摘要
目的:本实验观察SD大鼠坐骨神经完全切断再植后,中药三七对大鼠自噬行为和神经修复的影响。方法:将20只完全切断坐骨神经吻合术后大鼠随机分成中药组和空白对照组(10只/组),分别观察6周内损伤侧足趾自噬情况。于术后第6周、第10周用肌电图仪电刺激大鼠的坐骨神经远、近端,在腓肠肌肌腹部记录复合肌肉动作电位与运动神经传导速度,并与健侧对照。结果:①三七组的大鼠自噬脚趾评分较低,与对照组比较差异有显著性意义(P<0.05)。②三七组动物损伤侧神经传导检测,复合肌肉动作电位波幅在10周时上升(P<0.05),优于对照组,差异有显著性意义。结论:三七能够显著地减轻神经病理性疼痛,抑制大鼠的自噬行为,对周围神经再生的影响是有益的。
Objective:To observe the effect of notoginseng on autophagy behavior and repairing of rat's sciatic nerve after complete transection and anasmosis.Method:Twenty SD rats were used.The right sciatic nerves of rats were transected at the site on sciatic notch and anastomosed immediately,then randomly divided into two groups:notoginseng group and control group.The right toes autophagy behavior was observed.Electric stimulation was performed at the distal and proximal parts of sciatic nerve trunks;compound muscle action potential(CMAP) and motor nerve conduction velocity(MCV) were detected at the 6th week and 10th week after operation,and compared with the unaffected control.Result:The autophagy behavior of right toes was lighter in notoginseng group than that in control group.The amplitude of CMAP in notoginseng group was higher than that in control group.Conclusion:Notoginseng can remarkably alleviate neuropathy ache and inhibit autophagy behavior.It can also contribute to peripheral nerve regeneration after reimplantation.
