Methods: Internodal length, the densities of myelinated fiber and unmyelinated fiber, g ratio(axon diameter:fiber diameter) of sural nerves from 7 peroneal muscular atrophy patients were measured and compared between HMSNⅠand Ⅱ.

测定7例腓骨肌萎缩症（遗传性运动感觉神经病，HMSNⅠ和Ⅱ型）患者腓肠神经的节间长度、有髓纤维和无髓纤维的密度以及轴突直径与纤维直径之比，并比较HMSNⅠ和Ⅱ型间上述参数的差异。

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.

为此，本研究采用改良的胶质细胞混合培养与差速贴壁方法获得大鼠OPCs，使用无血清培养基进行扩增、培养，用免疫组织化学和流式细胞技术对培养细胞的纯度进行鉴定，对少突胶质系细胞表达部分营养因子的情况进行检测；采用TUNEL、MTT等方法对少突胶质系细胞条件培养基对原代培养小脑颗粒神经元的保护作用进行检测；将OPCs移植入成年SD大鼠玻璃体内，利用上丘逆行荧光标记技术，观察眼内移植的OPCs对眶内视神经切断时的视网膜神经节细胞的保护作用及其持续时间；将OPCs或NSCs移植入新生和幼年SD大鼠玻璃体或视网膜内，观察不同时期视网膜内髓鞘形成与分布特点，分析髓鞘的超微结构，并观察眼内髓鞘形成对损伤神经节细胞的保护作用。
