The notable proliferation was not observed by eyes in the local of injection. The infiltration of inflammation cells and mild proliferation of fibrocyte around dura mater was observed by HE stained in 4 and 8 weeks after injection. Infiltration and exudation of inflammation cells was observed by HE stained in epidural nerve root. Compared with group A, no changes of group B, C and D were observed under specific stained. Proliferation of type Ⅱ collagen fibers around dura mater was seen under immunohistochemical stained in 4 and 8 weeks after injection. There is no significant demyelination changes under LFB stained. The thickness and shape of the myelin sheath in epidural nerve root was not regular under transmission electronic microscopy in 4 and 8 weeks after injection. Fibroblast was also seen there. In nerve endometrium, macrophage could be seen under TEM, myelinated nerve fiber changed significantly, but nonmyelinated nerve fiber changed mildly. When 8 weeks, the changes of group D is smaller than the group B and C.

给药局部肉眼观察未见明显的纤维组织增生；HE染色可见B、C、D三组给药后四周及八周时硬膜内外均有炎细胞浸润，纤维细胞轻度增生，硬膜外神经根内有炎细胞浸润及炎性渗出；特殊染色B、C、D三组同A组相比未见有脊髓及神经根的改变；免疫组化染色，给药后四周及八周时，硬膜内外均有Ⅱ型胶原纤维增生；固兰染色B、C、D三组未见有明显脱髓鞘改变，与A组相比无明显异常改变；电镜观察B、C、D三组在给药后的四周及八周时，表现为硬膜外神经根内髓鞘厚薄不一，形状不规则，可见成纤维细胞，神经内膜中可见有巨噬细胞；粗大的有髓神经纤维变化明显，无髓神经纤维受累较轻；八周时电镜下D组改变较B、C两组为轻。

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。

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。

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。

Subdiaphragamatic vagotomy plus VP group and sham operation plus visceral pain group, and each group has 6 rats.

应用免疫组化染色方法，观察各组动物Fos在巾枢延髓孤束核及胸髓的表达。

Motheds: to select 336 lomars with pulposis or apicitis from the aged and to devide them into two groups. in group the control group,the illed teeth were given only the root canal therapy. in group the experimental group, according to the difference of every root canal, the unobstructed root canals were treated by root canal therapy. while the obstructed ones were given the root canal resinifying, use two kinds of therapy method together to molais' pathological changes.then their curative effects were observed after two year.

选取336例中老年人患有不可复性牙髓炎、牙髓坏死、牙髓钙化、牙内吸收和急、慢性根尖周炎的患牙358颗，随机分为对照组和实验组，对对照组行常规根管治疗，对实验组则根据每个牙齿各根管的不同情况，采用根管-塑化联合治疗，观察2年进行临床评价。

The laboratory findings of a typical CCML patient comprised of peripheral blood leukocytosis, basophilia and eosinophilia,myeloid differentiation in different stages, and increased megakaryocytes. The immunohistochemical features of the CCML consisted of highly positive MPO and CD68, significant lowering of neutrophil alkaline phosphatase, positive for Philadel- phia chromosome or chimeric BCR/ABL gene, etc. But in most cases of juvenile CCML, the Philadelphia chromosome could not be detected.

临床表现以乏力、低热、贫血、肝脾及淋巴结肿大为主要特点；典型儿童慢性髓细胞白血病的实验室特点有白细胞计数高、嗜酸和嗜碱性粒细胞增多、骨髓不同阶段髓细胞分化和巨核细胞增多；免疫组化提示CD68，髓过氧化物酶，中性粒细胞碱性磷酸酶积分明显减低，Ph染色体或BCR/ABL融合基因阳性，而幼年型CCML的Ph染色体常为阴性。

Methods: Model of experimental rat pulpitis was established and ICAM-1 expression of normal dental pulp, pulpitis of immediate group,1 day ,3 days, 5 days, 7 days was analyzed by using immunohistochemical and image analysis technique.
