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.

分别于术后7、14、30和90d应用酶组织化学方法、电生理方法、HRP （hydrogen-peroxide oxidoreductase）逆行示踪方法、轴突图象分析方法以及坐骨神经功能指数（sciatic nerve function index，SFI）测量等方法检测坐骨神经损伤后对应脊髓神经元的存活率、神经元胞体酶系变化、损伤神经在轴浆运输、电传导以及轴突、髓鞘再生等方面的恢复情况，探索外周神经损伤后OECs及几丁质对神经元的保护作用以及对新生神经功能恢复的作用，为外周神经损伤的治疗提供新的理论基础。

After analysis of multiple sequences alignment, phylogenetic tree and similarity of sequences, it was shown that Ac-ASP has similar relation with Am-ASP, and shared high homology with other Hymenopteran and Coleopteran. From above analysis, we firmly suggest Ac-ASP1 and Ac-ASP2 belong to OBPs family and Ac-ASP3 belong to CSPs family.

通过多序列联配、系统发育树及序列相似性分析，Ac-ASP除与西方蜜蜂Am-ASP亲缘关系较近(相似性达到80％以上)外，与其它膜翅目以及鞘翅目的OBPs及CSPs也有一定的亲缘关系(相似性达到30～60％)，且Ac-ASP1和Ac-ASP2应为OBPs，Ac-ASP3则应为CSPs； 4。

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。

Methods Under femoral artery puncture and catheter introducer leaving,bilateral common carotid artery angiography was pertormed with 4F HeadHunt or simmons angiographic catheter.We superselectively inserted the catheter to the branch of external carotid artery after confirming the bleeding site,hemorrhagic artery and externalinternal cranial dangerous anastomoses.

用Seldinger技术经股动脉穿刺，置入导管鞘，进4F HeadHunt导管或Simmons导管行双侧颈总动脉造影，明确出血部位，出血动脉及有无颅内外危险吻合后，将导管超选择性插入出血的颈外动脉分支。

These diseases included enormous schwannoma caused by intercostal neuve,ancomplete type neourofibramatosis,enormous ganglioneuroma in sacrococcyx,A skin tumor of chest wall and enormous retroperitoneal extradural cyst.

包括源于肋间神经巨大神经鞘瘤、不完全型神经纤维瘤病、骶尾部巨大神经节细胞瘤、胸壁 Askin瘤和腹膜后巨大的硬脊膜外囊肿，着重对其 X线诊断进行探讨。

They all have the typical structure of leaf of C4 plant, but out of the ordinary is that the structure of the midrib is alike the parallel veins and there is a layer of fiber cells between the phloem and the bundle-sheath of vein in the midrib and big parallel veins while the outer wall of the bulliform cells is less cuticularized.

摘 要：以7个杂交狗牙根品种的叶片进行解剖研究，结果表明，各品种均具禾本科 C4植物叶片典型结构，其独特处是：中脉结构与平行脉相似；中脉维管束、平行脉大维管束的维管束鞘内侧韧皮部外有一层纤维细胞；泡状细胞外壁很少角化。

This observation provided a strong support to the point that most leaves export the most of assimilates in the light time. Plasmodesmal densities between SE/CC, CC/PP, PP/PP and PP/BSC (bundle-sheath cell) decreased in weak light. Plasmodesmata were observed between CC/SE (nacreous-walled sieve element), PP/BSC in branch veins in normal light intensity, but not in weak light. Thus apoplasmic pathway may be the main mode of transport of assimilates in weak light, however symplasmic pathway may be the main mode of transport of assimilates in normal light intensity.

在筛管/伴胞、伴胞/韧皮薄壁细胞、韧皮薄壁细胞/韧皮薄壁细胞和韧皮薄壁细胞/维管束鞘细胞之间的胞间连丝密度都在弱光条件下下降，在正常光照强度下支脉筛管/伴胞和韧皮薄壁细胞/维管束鞘细胞之间可以观察到胞间连丝，而在弱光下几乎观察不到胞间连丝的存在，所以同化物的运输在弱光条件下可能以质外体运输为主，而在正常光照强度下，共质体运输可能是主要的运输方式。

The third-stage larvae were developed to fourth-stage larvae (the most optimal develop rate was 41%) when cultured in defined complete medium, further, cultured in defined incomplete medium, was examined no develop and a poorly survival rate. When the third-stage larvae were cultured in the defined complete medium under 37℃ and 5% CO2 in air, the larvae were began to develop to the fourth-stage larvae in cultured for 30 days, being enclosed within the sheaths of the third molts of life cycle.

广东住血线虫的第三期幼虫以MEM medium添加胺基酸、脂肪酸及碳水化合物的培养基在37℃含有5％ CO2的无菌培养箱中，培养至第21天已发育至第三期幼虫中期的阶段，第24天已发育至第三期幼虫末期的阶段，第30天开始出现带鞘的第四期幼虫，第36天则观察到虫体明显变长并蜕去外鞘及第三期幼虫特有的眼点消失的第四期幼虫。
