轴突

LITERATURE EVALUATION: Of 31 articles, 23 were included in the study on the regeneration and repairing of neuron, neuraxon and myelin sheath post spinal cord injury, and 8 related to the present problems and the prospect.

文献评价：符合纳入标准的31篇文献中，23篇涉及移植后损伤脊髓神经元和轴突、髓鞘的再生及功能修复的研究，8篇涉及存在的问题与展望。

The thickness of myelin sheath of experimental group was inferior to that of group B (P.05) at the third month, while the number and diameter of axons in both groups was similar.

这种无细胞基膜管移植体能支持轴突的生长和雪旺细胞的迁移，是一种良好的神经移植替代材料。

And large gaps were seen between axon and myelin sheath and intermyelin sheath layers.

可见轴突与髓鞘间及髓鞘板层间形成宽大的裂隙。

NGG contributes to axon growth and myelination, and thus promotes peripheral nerve regeneration in rats with functional recovery.

NGG有利于轴突生长和髓鞘形成，可以促进大鼠损伤神经修复和神经功能的恢复。

So, we speculate that amelioration of axonal myelination after SCI will be favorable for the functional recovery of the injured spinal cord.

因此，我们推测改善脊髓损伤后轴突髓鞘化可有助于损伤脊髓神经功能的恢复。

Objective: To study the axonal effect and the expression of integrin α6β4 during Schwann cell differentiation and myelination.

目的：探讨轴突对施万细胞(Schwann cells， SC)分化成熟与髓鞘形成的影响，及在SC的极向分化过程中整合素α6β4的表达。

But, deep myelination, or the erosion of the protective sheath around the axons of neurons, may not be reversible if B-12 deficiency is severe or long-term, she said.

但是，她说，如果长期严重缺乏B12，一旦髓鞘已经形成，或神经原轴突周围的保护性鞘已受侵蚀就是不可逆的了。

Administration of NGF may treat the spinal cord and periphery nerve injured and improve the function of damage nerve.

神经生长因子是最先发现和被证实的细胞生长调节因子，NGF在神经细胞的增殖，分裂和轴突的生长、递质的合成及细胞的凋亡等阶段均起着重要作用，NGF对中枢和周围神经的损伤均有保护和促进恢复的作用，尤其是NGF促进神经细胞的再生，给予NGF可减轻和改善对神经元的损害和治疗外伤引起的脊髓和周围神经损伤。

Physiologic and physical parameters of small nerve fiber were measured.

观察了细小神经轴突膜电生理和物理特性参数。

Neurite regeneration from central nervous tissue of mammalian has been demonstrated to occur in early postnatal stage but not in adult stage.

刚出生的哺乳动物之中枢神经组织在体外培养具有神经轴突再生的能力，但是成人期的中枢神经组织就丧失此能力。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
