In this paper, we first analyze the mechanism of action potential propagated alongan unmyelinated fiber, and present a hypothesis that the velocity of transmembranecurrent is the equivalent of the propagation velocity of action potential. Then usingthe H-H model and the cable equation we obtain the formula of the velocity. Insuccession, we apply a similar method to analyze the mechanism of action potentialpropagated along a myelinated fiber. Using the McNeal model and the CRRSS model,we obtain the formula of the velocity.

Recently, many foreign researchers found that the tetrodotoxin-resistant voltage-gated sodium channel, Nav1.8, which is expressed only by unmyelinated small-diameter sensory neurons associated with nociception in dorsal root ganglion and trigeminal ganglion, is involved in pain pathways and play a key role. Thus it provides a new idea in pain research.
近年来，国外众多学者发现河豚毒素(tetrodotoxin，TTX)不敏感型(TTX-resistant，TTX-R)电压门控钠通道Na_v1.8与疼痛的关系极为密切，其仅分布在背根神经节(dorsal root ganglion，DRG)和三叉神经节(trigeminal ganglion，TG)中的与伤害性感受密切相关的无髓鞘的小直径感觉神经元胞体上，它为疼痛的研究提供了新的思路。

We introduced improved primary mixed glial culture and different-attachment method to isolate and purify the OPCs, the cells were proliferated in serum-free medium, flow cytometry and immunohischemistry methods were employed to estimate the purity of cultured OPCs. Their abilities of differentiation and expression of trophic factors were identified by RT-PCR and immunostaining. Several methods including TUNEL and MTT were adopted to estimate the protective effects of conditioned culture medium from oligodendrocyte lineage cells on the primary cultured cerebellar granule neurons. Intravitreal transplant of OPCs, combined with retrograde fluorescent labeling the superior colliculus and intraorbital optic nerve transection, were used to investigate the protective effects of OPCs on the axotomized RGCs in vivo. Intravitreal transplantof OPCs or NSCs on the newborn rats, and retinal transplant of OPCs on the young rats were performed, to observe the myelin formation in the retina at different stages after cellular transplantation. Optic nerve transection was carried out on some rats with myelinated retinae, to study the influence of myelination on the injuried RGCs.

Results Under our experimental conditions, three kinds of NO donors when in lower concentrations could not cause obvious changes of axons while when the concentration of DETA NONOate was doubled, it could induce the non-selective demyelination and Wallerian degeneration of both sensory and motor nerve fibers.
结果：在本实验条件下，应用三种NO供体的低浓度，都不能引起大鼠坐骨神经轴突的改变；将DETA NONOate浓度加倍则可导致轴突脱髓鞘和沃勒变性，但对有髓鞘纤维和无髓鞘纤维并无选择性作用。
