坐骨神经的

Methods The sciatic nerve trunk of toad was isolated and stimulated with electricity of varied parameters. The time required was investigated for the action potential to reduce its conduction velocity by 20% and to extend the latent period by 20% respectively.

用不同的电刺激参数刺激坐骨神经干，测定引起的动作电位的幅度和传导速度分别衰减20%以及潜伏期延长20%时所需的时间。

For sciatic blocks, cold sensation had a sensitivity of 77% and a specificity of 100%, whereas pinprick had a sensitivity of just 20% with a specificity of 100%.

而坐骨神经阻滞对温度刺激的 PFI 的敏感性和特异性为77%和100%、对痛觉刺激的 PFI 的敏感性和特异性分别为20%和100%。

By way of four complete reflex arcs of comparative test and destroyed reflex arcs,it is showed that the reflex arc consists of sensory receptors,efferent nerve fibers,nerve center,efferent nerve fibers,effecter,and that the four parts must exist together.The test phenomenon is clear after improving the experimental methods,and the rate of success reaches 95%.

从各类实验教材来看，我们发现其证明传入神经和传出神经是反射弧的组成部分的方法有些过于简单[1~3]，不能区别传入神经和传出神经的功能效应；有的使用普鲁卡因麻醉坐骨神经干[4]，麻醉的时间和程度不好把握，很难圆满完成实验，造成实验失败。

Objectives A rat model sciatic nerve crush injury was reproduced in rat, and behavioral changes, pain threshold, thermal withdrawal latency and the changes in c-fos expression in cornu dorsale medullae spinalis were examined, and the relationship between peripheral nerve regeneration and hyperpathia was explored.

目的 建立大鼠坐骨神经挤压模型，观察其神经恢复过程中行为学、机械痛阈值、热缩足反射潜伏期以及脊髓背角c-fos表达（对c-fos表达产物：Fos蛋白阳性的神经元进行计数）的改变，探讨外周神经损伤再生与痛觉过敏的关系。

objective to study the effects of ethanol extract of the huangqi on the skeletal muscles contractility in rats.methods the gastrocnemius and soleus muscle contractility were observed by stimulating the sciatic nerve with electricity after affusing stomach with ethanol extract of the200mg/kg dosage of huangqi for2weeks.results the ethanol extract of the huangqi could shorten latent period,increase maximal contractive extent and time and relaxative time at the twitch and complete tetanus of gastrocnemius and soleus muscles.conclusion the ethanol extract of the huangqi can enhance skeletal muscles contractility in rats.

方法］ 灌胃给予200mg/kg黄芪酒精提取液2周后，观察大鼠坐骨神经受刺激后腓肠肌及比目鱼肌的收缩力。［结果］黄芪酒精提取液缩短腓肠肌及比目鱼肌单收缩和完全性强直收缩潜伏期，增加单收缩最大收缩幅度，延长最大收缩时间及最大舒张时间；增加完全性强直收缩的最大收缩度，延长最大收缩时间。［结论］黄芪酒精提取液可增强大鼠骨骼肌的收缩力。

Objective To investigate the change of SSeCKS in sciatic nerve after the transection of rat sciatic nerve and its significance.

目的 探讨大鼠坐骨神经切断后，Src抑制的蛋白激酶C的底物在神经中的表达变化及其意义。

It was observed by Nissl and enzyme histochemistry staining that exogenous GDNF decreased lesion-induced motor neuron death in lateral nucleus of spinal anterior horn and the changes in activity of cholinesterase and acid phosphatase in spinal cord and sensory ganglions.

采用硅管套接大鼠切断的坐骨神经模型，局部给予胶质细胞源性神经营养因子，应用尼氏染色、酶组织化学染色方法，观察到外源性GDNF能减少脊髓修复侧前角运动神经元死亡的数目，降低脊髓前角运动神经元及脊神经节感觉神经元中胆碱酯酶及酸性磷酸酶变化的幅度。

Degradation of poly-d,l-lactide in vivo and 20mm nerve gap rec overed by poly-d,l -lactide guide were reported.
