Of creatures that can fly and are bloodless some are coleopterous or sheath-winged, for they have their wings in a sheath or shard, like the cockchafer and the dung-beetle; others are sheathless, and of these latter some are dipterous and some tetrapterous: tetrapterous, such as are comparatively large or have their stings in the tail, dipterous, such as are comparatively small or have their stings in front.

一些能飞并且无血的动物是鞘翅类动物，因为它们把翅膀藏在鞘中，像是金龟子和蜣螂；一些是无鞘的，后面一类中一些是双翅的，一些是四翅的：四翅的，就像是那些相对较大的，或者刺在尾部的；双翅的，就像是相对较小的，或者刺在前方的。

Neural cell adhesion molecule L1, discovered in the 80s, is one of the matters that can promote nerve regeneration. It can mediate the interaction of cell-to-cell and cell-to-matrix, take great efforts on neurite outgrowth and fasciculation, migration of neural cells, formation of the myelin, structure of neural trace, transmembrane signal transduction, inhibiting apoptosis of neural cells, even on immune system and formation of the tumor. Li is discovered on the mouse's Cerebellar membrane primarily. Thereafter, it also is found in post- mitotic neurons, pre- and non-myelinating Schwann cells and so on.

神经细胞粘附分子L1（L1）是80年代发现的具有促进神经再生作用的物质，它能介导神经细胞与神经细胞之间的粘附，在神经轴突的生长、聚集，神经细胞的转移，纤维髓鞘的形成，神经通路的构建及信号的转导，抑制神经细胞的凋亡甚至在免疫系统、肿瘤的发生等方面均具有非常重要的作用。L1最初是从小鼠的小脑膜中发现，后来发现在有丝分裂后的神经元，髓鞘形成前及非形成髓鞘的雪旺细胞等组织中同样存在。

To destroy or remove the myelin sheath of, as through disease.

髓鞘碱性蛋白是组成中枢神经系统髓鞘的主要蛋白，约占髓鞘蛋白质总量的30%。。。。

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 results showed the variation and ranking of genotypes based on the relative value of proline content, SOD and CAT activity of plumule was rather similar to that based on the yield reduction rate in field water deficit experiment.

结果表明，在渗透胁迫条件下，不同小麦品种萌发期胚芽鞘的脯氨酸含量、胚芽鞘和胚根的MDA含量升高，而胚芽鞘和胚根的SOD、CAT活性以及可溶性蛋白质含量下降。

The enzyme-linked immunosorbent assay was used for the content measurement of myelin basic protein in telencephalon tissue at 1 week, 1 month, 3 months and 6 months after irradiation.

SD大鼠受2、10或30Gy全脑照射后的1周以及1、3和6个月时，采用酶联免疫吸附法测量脑组织中髓鞘碱性蛋白含量、用Luxol fast blue染色法和电镜观察并分析髓鞘的病理学改变。

One or more bundles of myelinated or unmyelinated fibers in the peripheral nervous system.

周边系统中一束或多束具髓鞘或不具髓鞘的纤维。

The plasmid of pEGFP-N1 was preserved in our laboratory.②The rat vibrissa follicles were dissected under a stereomicroscope. The dermal sheath was moved by incubated in dispase. The bulge regions of the hair follicles in anagen phase were carefully cut between the arrector pili muscle and the sebaceous gland, and then incubated with a mixture of trypsin and EDTA. The cell suspension was selected, and cultured in 10% fetal bovine serum DMEM/F12 FAD medium. After 7 days culture, HFSC was obtained by rapid adhering on collagen Ⅳ.

实验方法：大鼠在体视显微镜下分离出含真皮鞘的完整毛囊，dispase消化，将毛囊从真皮鞘中挤出，收集形态完好且处于生长期的毛囊，分别在毛球部上端、皮脂腺下端横切毛囊，取中间部分置于胰酶和EDTA中联合消化，向所得细胞悬液中添加含10%胎牛血清DMEM/F12完全FAD培养基，常规培养7 d后，采用IV型胶原快速贴壁法两次筛选以分离纯化大鼠毛囊干细胞。

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。

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。
