神经外膜

The fine vessel braneh could be found on epineurium and periheurium in 3 days, the capillary network has been formed in the midportion of the nerve segment and spread toward two sides in 7 days, from 14 to 21 days, the capillary network spreaded through the whole grafts and conrected with the capillaries from the two ends.

术后3天，血管已在神经外膜和束膜上形成微小分支。7天移植神经的中段已形成毛细血第四军医大学硕士研究生毕业论文管网，并向两端扩展，而自两端长入的血管则较少。14天至刀天，血管网己分布在移植神经段的全段及各层，并与两端长入的毛细血管相吻合。

After disposal,schwann cells, myelin sheath and axon of nerve fibers were eliminated,but the basement membrane tube of schwann cells and three-dimensionalsupports of extracellular matrix of epineurium and perineurium werereserved.

经脱细胞处理后，去除了Schwann细胞、神经纤维的髓鞘和轴突，保存了由Schwann细胞基底膜管以及神经外膜和束膜的细胞外基质构成的三维支架结构。

The microsurgical decompression on cerebromedullary tube stenosis, epineurium and bundle membrane among patients with diabetic peripheral neuropathy can relieve numbness and pain for the patients. The function of the nerves can be improved too.

糖尿病周围神经病经过在显微外科手术下进行神经管道性狭窄松解及神经外膜、束膜的松解后能明显缓解病人的麻木、疼痛症状，神经功能有一定的恢复。

In experimental side, the peroneal nerve was transected, the distal segment was kept close to neighboring tibial nerve at suitable site, and then the epineurium and perineurium of two neigh...

实验侧 ：将腓总神经在大腿下 1/3处切断，断端结扎后将其远端与相邻胫神经干适当松解后靠拢，纵行切开两神经相邻侧面的神经外膜、束膜长约 0.5 cm，至部分神经纤维外露。

Part three: An experiment study on the repair of peripheral nerve injury by NT-3 gene modified neural stem cells objective To investigate the effective treatment of peripheral nerve injury with NT-3 gene modified neural stem cells, to explore the feasibility of the treatment by means of gene transfection Methods 54 SD rats were divided evenly into 3 groups. The sciatic nerve transected model were made and sutured end to end with epineurium. The neural stem cell without NT-3 gene or with NT-3 gene modified were injected into triceps muscle one time a week, saline injected as control group. The nerve trunks of stomas and triceps muscle were acted as specimen three weeks、six weeks and nine weeks after operation.

最后，为了探讨神经营养素-3基因修饰的神经干细胞对周围神经再生修复的影响，从转基因角度探讨治疗周围神经损伤的有效方法，我们选用54只SD大鼠随机分为3组，造成坐骨神经切断损伤模型，神经外膜端端对位缝合后，于小腿三头肌每周分别注射生理盐水、未被神经营养素-3基因修饰的神经干细胞、及神经营养素-3基因修饰的神经干细胞。

Methods: 60 Wistar rats were randomly divided into three groups, with 20 rats each. The right radial nerve was repaired with end-to-side fashion after windowed, the distal end being sutured to the epineurial window (0.12 cm×0.12 cm) 0.15 cm distal of the medial fasciculus. The left radial nerve was only windowed as control.

Wistar大鼠60只，随机分为3组，每组20只，每只右侧神经外膜开窗（0.12 cm×0.12 cm），将臂丛后束损伤后的桡神经远断端端侧吻合于外膜开窗的内侧束远端0.15 cm部位，左侧不做吻合。

The time from injury to admission was between 2 monthes214 monthes except 1patient who underwent emergency operation 4 hours after injury ,and 1 patient was treated with debridment and epineurial neurorrhaphy ,7 cases with nerve trunk grafting ,6 cases with nerve cable grafting ,4 cases with neurolysis ,1 case with arthrodesis of ankle.

伤后至入院手术时间除1 例为4 h 外，其余均为2～14 个月。1 例行清创、神经外膜对端吻合术，7 例行神经全干移值术，6 例行神经电缆式移植，4 例行神经松解术，1 例行踝关节融合术。

The lesion was very uncommon. The etiology may be a focal inflammatory response around the feeding arteries in the perineurium. The results of surgical treatment were good.

非创伤性桡神经麻痹伴神经多段束带样病变临床罕见，其病因可能是神经外膜、束膜内的血管炎；手术治疗效果良好。

Under the identical experimental conditions, cut the trunk of the right facial nerve. Two weeks later. the caudal end of the divided facial nerve was anastomized with the cephalad end of the divided main trunk of the nerve to the masseter muscle.

在相同实验条件下，切断家兔右侧面神经主干，造成完全性面瘫。2周后，寻出麻痹侧面神经远心端与嚼肌神经主干近心端，在手术显微镜下做神经束膜、神经外膜吻合。

Results: The microvessels of the trigeminal nerve root included epineurial, perineurial and endoneurial vessel.

结果：三叉神经根的微血管分为神经外膜、神经束膜和神经内膜微血管。
