神经鞘的

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。

Myelin sheath thickness and maturity was superior in EFG group under electron microscopic observation.

超微结构观察：EGF组再生神经的有髓纤维数，髓鞘厚度，髓鞘的成熟度明显好于对照组。

The ultrastructure studies show that the number of mitochondria in the motor neurons from resistant strain are higher than those of the susceptible strain, and the thickness of neural lamella and perineurium of resistant strain is thicker than those of the susceptible insects.

棉铃虫抗性种群、对照种群、同种群不同龄期幼虫以及同一个体胸、腹神经节的神经细胞体外培养时形态无明显差异，但抗性品系幼虫运动神经元内线粒体明显增多，且神经围鞘与神经节膜厚度之比明显增加。

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。

The total syntheses of sphingosine , ceramide and glycosphingolipid were reviewed with emphasis on the recent progresses.

综述了神经鞘氨醇、神经酰胺及鞘糖脂全合成研究的基本概况，重点评述了其最近的研究进展情

In particular,peripheral contrast enhancement with separations of an intradural extramedullaty tumor on MRI will suggest the diagnosis of schwannoma.

椎管内髓外硬膜下神经鞘瘤的MRI特征，有助于椎管肿瘤的鉴别诊断，尤其是伴有瘤内分隔性周围强化，应提示神经鞘瘤。

Schwannomas are typically benign, slow growing tumors that arise from the schwann cells, which envelop and myelinate cranial, spinal, and peripheral nerves.

神经鞘瘤是典型的良性、缓慢生长的肿瘤，起源于许旺细胞，包绕并形成颅内、脊髓以及周围神经髓鞘。

Background: Peripheral nerve injury is common and serious in clinically. According to the nerve regeneration theory of nerve tropism, neural regeneration room became hot spot for treating nerve injury.Then keep distance between the proximal and distal severed stumps with different conduits and others substance which can promote nerve regeneration ,the room can provid a favourable environment for nerve regeneration. a series of empirical study indicated immunosuppressant FK506 can promote nerve regeneration, chitosan is polysaccharose natural biomaterial , Chitosan is prepared by the N-deacetylation of chitin.

背景：周围神经损伤在临床上比较常见，根据神经趋向性再生理论，神经再生室成为神经损伤治疗研究的热点，即在神经断端之间留出一定的间隙，并套以不同材料的鞘管及其它促进神经再生的物质，为周围神经再生创造良好的再生环境，一系列实验研究表明免疫抑制剂FK506有促进神经再生的作用。

In acoustic neuromas, patients with LOH were younger at the age of diagnosis, and larger tumor size, had shorter history and higher growth rate. Conclusions CHR22 LOH was a frequent event in the tumorigenesis of sporadic schwannoma. The presence of CHR22 LOH was related to clinical features.

CHR22 杂合子丢失是神经鞘瘤发生中的常发事件，缺失的区域包括NF2基因，CHR22 杂合子丢失与听神经瘤的临床行为有一定的关系，CHR22 杂合子丢失可能是神经鞘瘤增殖的重要因素。

Schwannomas are peripheral nerve sheath tumors with a slow growth rate. They rarely occur in the retroperitoneum or pelvis.

神经鞘瘤是生长速度缓慢的周边神经鞘肿瘤，很少发生在后腹腔或骨盆腔。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
