髓鞘化

Large numbers of experiments internal and external had confirmed both direct current and square pulse of distal end cathodal could improve peripheral nerve regeneration, because it could speed up transmigration, creeper, growth and development of cell Schwann, derivate growth of nerve fiber; it also increased blood capillary of epineurium, brood blood vessel, amendment ischemic of impaired nerve, it still could accelerate Wallerian

国内外大量的基础实验及临床研究都证实远端负极电流的直流电场及脉冲电场等均有促进周围神经再生的作用，认为其可加速Schwann细胞的游走、爬行及生长发育，诱导神经纤维的生长；电刺激还能促使神经外膜毛细血管数量增多，扩张血管，改善神经损伤段缺血状态，并加速Wallerian变性及崩解组织的清除，为Schwann细胞发育和髓鞘化过程提供充足的能量与物质，同时为神经轴突的再生提供良好的内环境；在神经断端出现瘢痕或神经瘤时，电刺激可增加神经纤维穿越瘢痕的能力。

The process of myelination is extremely complex.

髓鞘化的过程非常复杂。

Objective: To investigate the effect of endogenous brain-derived neurotrophic factor on the myelination of the postnatal peripheral nerve in rats.

目的：探讨脑源性神经营养因子对出生后大鼠周围神经髓鞘化的作用及其作用机制。

BACKGROUND: Myelination following axonal regeneration is a key factor affecting the recovery of spinal cord injury.

背景：轴突再生后髓鞘化是影响脊髓损伤后恢复的一个关键性因素，而少突胶质细胞存活的多少直接影响轴突再生后髓鞘化。

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。

Endogenous BDNF affected myelination of postnatal peripheral nerve through p75 and NP-kappa B signal transduction pathway.

内源性BDNF影响出生后大鼠周围神经的髓鞘化，尤其在早期作用明显；内源性BDNF主要通过p75和NF-κB信号途径调节出生后大鼠周围神经的髓鞘化。

Comparison of the cerebellar cortex and the neocortex. Note that the fiber tracks are white and the cell layers are tan. The white is due to the myelination of the fiber bundles.

比较小脑皮质与大脑新皮层，请注意神经纤维径为白色，而细胞层为棕色，白色部分是由於神经纤维束的髓鞘化。

Methods: The myelination of the sciatic nerve was measored with light microscope and electron microscope; the expression of p75 in the sciatic nerve was measured by Western blot; the nuclear translocation of NF-kappa B in the sciatic nerve were showed by immunofluorescence.

用光镜和电镜方法检测坐骨神经纤维的髓鞘化情况；用免疫印迹方法检测坐骨神经p75的表达；用免疫荧光方法检测坐骨神经雪旺细胞内核转录因子的表达。

Neurotrophic factors play an important role in the culture, proliferation and differentiation of stem cells, and regeneration and remyelination of neurite.

神经营养因子在干细胞的培养、增殖、分化以及轴索的再生和再髓鞘化等过程中发挥着重要作用。

Two weeks later, we measured the degree of the inclined plane and analyzed electrophysiological parameters such as latency, stimulus threshold and amplitude of MEP-C.

目前，多项研究表明OECs有促进轴突再生以及使脱髓鞘轴突重新髓鞘化的作用，因此有希望成为治疗脊髓损伤的一种新工具。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
