The lesion, the changes of activity of cholinesterase and acid phosphatase of motor neurons in lateral nucleus of spinal cord anterior horn, the function of axoplasm transportation and nerve conduction, the regeneration of axons and myelin sheath, and the recovery of sciatic nerve function were examined at 7, 14, 30 and 90 days intervals after operation, using Nissl and enzyme histochemistry staining, electrophysiological technique, hydrogen-peroxide oxidoreductase retrograde trace method, axon image analysis, and measurement of sciatic function index. The spinal cord anterior horn of injury side was compared to the correspondence region of spinal cord.

The notable proliferation was not observed by eyes in the local of injection. The infiltration of inflammation cells and mild proliferation of fibrocyte around dura mater was observed by HE stained in 4 and 8 weeks after injection. Infiltration and exudation of inflammation cells was observed by HE stained in epidural nerve root. Compared with group A, no changes of group B, C and D were observed under specific stained. Proliferation of type Ⅱ collagen fibers around dura mater was seen under immunohistochemical stained in 4 and 8 weeks after injection. There is no significant demyelination changes under LFB stained. The thickness and shape of the myelin sheath in epidural nerve root was not regular under transmission electronic microscopy in 4 and 8 weeks after injection. Fibroblast was also seen there. In nerve endometrium, macrophage could be seen under TEM, myelinated nerve fiber changed significantly, but nonmyelinated nerve fiber changed mildly. When 8 weeks, the changes of group D is smaller than the group B and C.

给药局部肉眼观察未见明显的纤维组织增生；HE染色可见B、C、D三组给药后四周及八周时硬膜内外均有炎细胞浸润，纤维细胞轻度增生，硬膜外神经根内有炎细胞浸润及炎性渗出；特殊染色B、C、D三组同A组相比未见有脊髓及神经根的改变；免疫组化染色，给药后四周及八周时，硬膜内外均有Ⅱ型胶原纤维增生；固兰染色B、C、D三组未见有明显脱髓鞘改变，与A组相比无明显异常改变；电镜观察B、C、D三组在给药后的四周及八周时，表现为硬膜外神经根内髓鞘厚薄不一，形状不规则，可见成纤维细胞，神经内膜中可见有巨噬细胞；粗大的有髓神经纤维变化明显，无髓神经纤维受累较轻；八周时电镜下D组改变较B、C两组为轻。

To isolate forebrain and hindbrain of human fetuses about 9 weeks and 12 weeks from spontaneous abortion. Neural stem cells were cultured in special culture medium and were compared with growth characterization.The differentiation from these neural stem cells was investigated in both a fetal bovine serum-containing and a non-supplemented,serum-free basal medium.

材料与方法：利用神经干细胞的条件培养基，对从9周和12周胚龄的自然流产胎儿分离的前脑、后脑进行神经干细胞培养，比较其生长特性，并分别观察在无生长因子的基础培养基以及含有胎牛血清的培养基中神经干细胞的分化情况。

With the development of lesion inautonomic nervous system, i.e. the elevation of baroreflex set point, blood pressureincreases to stage 1 hypertension and worsens. Furthermore, the role of the effectors,including PVR, ventricular end-systolic elastance, venous unstressed volumes and heartrate, in the regulation of hypertension was analyzed. The results exhibit that the ANSregulation on hypertension works mainly by the reduction of PVR and the increase ofvenous unstressed volume.

随着自主神经系统损坏程度的不断加重，即工作调定点进一步升高，血压水平上升到了1级高血压并趋于严重；研究了神经调节的各效应器(外周血管阻力、心肌最大弹性度、心率和静脉非压力容积)对高血压的作用，表明神经调节机制对高血压的调节主要是通过降低外周血管阻力和增加静脉非压力容积实现的。

Then transplantation of the sciatic nerve from donor rats to the recipient rats in two groups were progressed.7 days after nerve transplantation,the contents of cd4 and cd8 in peripheral plasma of recipient rats were detected by flow cytometry.8 weeks after nerve transplantation,transplanted nerve were observed under light microscope.results:compared with nonirradiated group,the percentage of cd4 and the ratio of cd4 to cd8 in uvb irradiated group were significantly decreased（p＜0.05,p＜0.01）,cd8 percentage was significantly increased（p＜0.01）.conclusion:uvb-irradiated donor splenocytes were injected in the recipient rats through caudal veil,which could induce immunological tolerance to allogeneic transplantation.

未照射组注射未经紫外线照射的供体脾细胞，照射组注射经紫外线照射的脾细胞，7 d后移植供体神经。术后7 d行外周血t淋巴细胞亚群检查，术后8 w行移植神经组织学检查。结果：照射组cd4+百分率、cd4+/cd8+比值较非照射组明显降低（p.01，p.05），cd8+百分率较非照射组明显升高（p.01）。组织学检查显示，照射组的再生神经较非照射组多。结论：尾静脉内注射经紫外线照射的异基因脾细胞可诱导对异体神经移植的特异性免疫耐受。紫外线；脾细胞；免疫耐受；坐骨神经

There was no necrosis or perineural invasion.

未发现坏死和神经周的侵犯。

Is there any need for expanding the perineural space before catheter placement in continuous femoral nerve blocks?

The figure of SFI showed that the functional recovery in the experimental groups was better than that of the control at every 10 days after sciatic nerve transection.

因此，OECs和几丁质对外周神经损伤所导致的脊髓神经元死亡和退行性变有较好的保护作用，对外周神经损伤后新生神经功能的恢复具有积极的促进作用。
