躯体运动神经元对ＮＧＦ是否具有应答能力至今尚缺乏直接证据［１，２］，我们采用自体静脉＋基底膜＋ＮＧＦ桥接兔坐骨神经１５ｍｍ缺损，探讨外源性ＮＧＦ对运动神经元再生的促进作用。材料与方法一、实验动物分组与桥接体制备健康兔２４只，体重约２－０～２－５ｋｇ。随机?
Somatic motor neurons have no response to NGF to date there is no direct evidence [1,2], we use autologous veins + basement membrane + NGF bridge rabbit sciatic nerve 15mm defect to explore the role of exogenous NGF on motor neuron regeneration. Materials and methods First, experimental animal grouping and bridging body Preparation of healthy rabbits 24, weighing about 2-0 ~ 2-5kg. random?
