髓鞘

Objective: To study the clinic and diagnostic value of CT and MRI of levamisole induced demyelinating encephalopathy.

目的：研究左旋咪唑致脱髓鞘脑病的临床及CT、MRI的诊断价值。

Results: electronic microscope showed that in prednisone group heterochromatin increased in some cells, entoblast was not obvious in some cells, fat drops were small and few, mitochondria vacuole were common, and myelin figure was found in smooth endoplamic reticulum. the ultrastructure in yc group was almost normal and megamitochondrion formation was common. a large amount of fat drops were found in cytoplasm in gw group and little improvement was found compared with that in prednisone group.

结果： 电镜结果显示：激素组个别细胞异染色质增多，核仁不明显，脂滴显著变小变少，线粒体空泡化常见，有滑面内质网髓鞘样结构形成；养阴组电镜结构基本正常，其特征是细胞内有较多的巨大线粒体形成；桂附组较激素组改善不明显，其特征是胞质内可见大量脂滴。

After disposal,schwann cells, myelin sheath and axon of nerve fibers were eliminated,but the basement membrane tube of schwann cells and three-dimensionalsupports of extracellular matrix of epineurium and perineurium werereserved.

经脱细胞处理后，去除了Schwann细胞、神经纤维的髓鞘和轴突，保存了由Schwann细胞基底膜管以及神经外膜和束膜的细胞外基质构成的三维支架结构。

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。

We observed highly significant changes of fiber orientations at regions that correspond to the superior longitudinal fasciculus during the first 5 years.

我们发现在出生后的开始5年，上纵束相关纤维束的区域定向发生明显改变。这个结果说明上纵束的轴突和髓鞘发育很慢，而这个区域被认为和语言功能相关。

These results support the idea that in the human fetal forebrain axonal PSA-NCAM expression is inversely related to primary myelination.

这些结果支持人的胎儿前脑轴突中PSA-NCAM的表达反而与最初的髓鞘形成有关的观点。

Results In both groups after injury, several changes on oculomotor nerve occurred including number reduction of neurons, dispersion in distribution, disappearance of sub-nuclear structure, structure destruction of fibers and myelin sheath, neurite gemmation, and specificity decrease in fibers distribution, while all these changes in section-suture group were more obvious.

结果 不同损伤均可导致神经元的数量减少，分布散乱，亚核分布结构改变，神经纤维和髓鞘的结构破坏，轴突芽生及再生纤维分布的特异性降低，而且上述改变在神经切断组更加明显。

Glia cells that produce the myelin sheath around axons in the central nervous system.

少数突神经胶细胞：在中枢神经系统的轴细胞周遭的髓鞘著产生的胶细胞。

SCI can cause hematomyel ia, dropsy, necrosis, capsular space, gummosis and so on, which can lead to neuron deprivation, demyelination of neurite. Clinical symptoms mainly manifest funct ion disorder of movement, sense, reflectance, and musculus sphincter below injury plan.

SCI后出现脊髓出血、水肿、坏死、囊腔形成、退变胶质化等一系列病理改变，以致神经元丧失、轴突脱髓鞘，临床表现为受损平面以下的运动、感觉、反射及括约肌功能的障碍。

The electron microscope showed increased number of mitochondrion and size of the transfected SGC7901 gastric cancer cells with NHE1 antisense gene, expanded Golgi apparatus, rough endoplasmic reticulum and endoplasmic reticulum and strengthened heteropolarity.

透射电镜下细胞线粒体数量增多、体积增大，并可见髓鞘样变，粗面内质网、高尔基体较发达，内质网扩张，核偏向一侧，极性增强。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
