The repair process of the iibial fascicle of the rabbit sciatic nerve which had been transected and sutured or simply crushed was studied by means of light and . electron microscopy.It was found that the perineurium was able to heal after the nerve had been transected and sutured through the formation of a new epineurium-perineurium tube which contained many minute fascicles of regenerated nerve fibers. The newlyformed epineurium-perineurium tubs rejoined ths two stumps of the transected epineurium theath perineurium tube. The healing process of the nerve fascicle after crushing was similar to that after transection and suturing.From the transection and suturing of the nerve to the formation of the new epineurium-perineurium tubs the sequence of pathological events occurring in the epineurium and perineurium could be divided into 3 stages, the first stage of trau-matic inflammation, degeneration and necrosis of the perineurium, the second stage of perineurial cell proliferation, and the regeneration nerve fiber growth into the pre-perineurium mass and the third stage of the formation of new small nerve fascicles.The formation of the new epineurium-perineurium tube is of vital importance to nerve regeneration, it can prevent the nerve fibers from growing astray and guide them to the distal perineurium tube. The pro-perineurial cells might originate from the proliferation of the perineurial cells, themselves.The normal histological and ultrastructural morphology of the rab bit sciatic nerve was described. The nuclei of the perineurial cells have the tendency to form palisades. It seems that this may explain the palisading of the nuclei of neurofibr-oma cells.

家兔坐骨神经胫神经束横断吻合和单纯挤压损伤后光、电镜对照观察,发现束膜损伤后能够修复,其方式是形成一含有许多神经小束的新外膜-束膜管,从而实现两断端束膜的再连接。神经切断缝合后至新外膜-束膜管的形成,外膜、束膜的变化可分为三期,即创伤性炎性反应,束膜变性坏死期,前束膜细胞增殖、神经纤维长入期与再生神经小束形成期。新外膜-束膜管的形成对神经的再生具有重要意义,能阻止新生的神经纤维向外生长并诱导其长入远端束膜管。作者考虑,再生束膜细胞可能来自束膜细胞本身的增殖。本文还描述了兔坐骨神经束膜的正常组织学和超微结构态形,束膜细胞核有作栅状排列的倾向,似可解释神经纤维瘤细胞每作栅状排列的现象。

Aim: We have studied the degeneration and regeneration of the Meissner corpuscles in order to estimate the clinical value of the delayed repair of peripheral nerve injuries. Methods: The specimens were taken in 8, 12, 30, 50 weeks after transections of the digital nerves respectively. Also we repaired the transected nerves 1 and 30 weeks after transection and took the specimens 50 weeks after repairment to observe the regeneration of Meissner corpuscles. Results: The regeneration nerve fibre was seen growing...

Aim: We have studied the degeneration and regeneration of the Meissner corpuscles in order to estimate the clinical value of the delayed repair of peripheral nerve injuries. Methods: The specimens were taken in 8, 12, 30, 50 weeks after transections of the digital nerves respectively. Also we repaired the transected nerves 1 and 30 weeks after transection and took the specimens 50 weeks after repairment to observe the regeneration of Meissner corpuscles. Results: The regeneration nerve fibre was seen growing into the remained Meissner corpuscles to repair nerves in the 12 week repairment group. And no Meissner corpuscles were found in the 30 week repairment group. The regenerated nerve fibre recovered its sensory function in the form of free nerve endings in the repaired nerves in 30 weeks, but it is impossible for the Meissner corpuscles to regenerate. Conclusion: The results of this experiment provided a theoretical basis for repairing peripheral nerve injuries in late stage.

bjective: To evaluate the possibility that collateral sprouting could occur from intact axons in an undamaged sciatic nerve. Methods: Bilateral sciatic nerves were exposed in the lower part of thigh, and the peroneal nerve was sectioned at the site of branch from sciatic nerve proper. The sciatic epineural window was created 10 mm above breaching. One end of silicone tube (60° slope) was sutured to epineural window, and other end to distal peroneal nerve stump. 6 mm gap was left within silicone tubing. The...

bjective: To evaluate the possibility that collateral sprouting could occur from intact axons in an undamaged sciatic nerve. Methods: Bilateral sciatic nerves were exposed in the lower part of thigh, and the peroneal nerve was sectioned at the site of branch from sciatic nerve proper. The sciatic epineural window was created 10 mm above breaching. One end of silicone tube (60° slope) was sutured to epineural window, and other end to distal peroneal nerve stump. 6 mm gap was left within silicone tubing. The right silicone tubing was filled with NGF, the left with normal saline (NS) as control side. Results: (1) There was a fine tissue bridging sciatic nerve to distal peroneal nerve stump in silicone tubing on NGF side 1.5 months after operation. In contrast, there was no tissue on NS side. The diameter of regeneration nerve on NGF side was equal to that of distal peroneal nerve 3 months after operation, the regeneration nerve was smooth without any scar formation. The diameter of regeneration nerve on NS side was thinner than that on NGF side. (2) Ultrastructural studies of collatreal sprouting nerve showed that there were more axons wrapped by thicker myelin shealth on NGF side, the tissue arranged in regularity. (3) Electrophysiological studies demonstrated that electrical impulses could conduct through the collateral sprouting nerve to made muscle contraction. The results of electrical stimulation on NGF side were better than that on NS control side. Conclusion: Collateral sprouting may occur from intact axons, perhaps induced by some actors emanating from the distal nerve segment, enhanced by exogenous nerve growth factor, and subsequently make functional peripheral connections.

目的:研究神经生长因子(NGF)及远侧神经残端诱导神经干侧枝的生长。方法:10只大白兔,于两侧胫神经、腓总神经分叉处切断腓总神经,分叉上1cm坐骨神经外膜“开窗”,硅胶管桥接“开窗”处和腓总神经远侧断端,中间留6mm间隙。右侧管内注入NGF,左侧注入生理盐水(NS)为对照侧。结果:大体观察NGF侧比NS侧神经侧枝再生快,直径粗。超微结构显示NGF侧比NS侧神经轴突数目多、髓鞘厚、组织排列整齐。电生理检测,NGF侧的诱发动作电位峰值(AMP)(2.5900±0.8568mV)、神经传导速度(CV)(76.0000±2.3457m/s)均优于NS侧的AMP(0.7089±0.1231mV)、CV(20.0000±1.5811m/s),t检验P均<0.01。结论:神经生长因子和远侧神经残端可诱导神经干侧枝的生长
