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。

Rhizosphere and bulk soils were extracted by low molecular-weight organic acids to fractionate Pb fraction of soil pools, which is considered as the phytoavailable Pb.

The effect of ferrous iron on the leaching rate of gallium and phosphorus was not significant.

镓和二价铁离子的沉淀率随磷酸根离子浓度的增加而增加，当磷酸根离子与金属离子摩尔比大于1：1后，磷酸根离子浓度对沉淀率的影响不再变化；温度对镓离子沉淀过程的影响较小，对二价铁离子的沉淀过程影响较显著。

Department of tooth crowns were removed and apical, dedicated root 6mm long, 50 teeth set up Enterococcus faecalis after root canal infection model, 20 teeth were placed in root canals cinnamaldehyde, gallnut decoction, Another 30 infected root canals placed FC, calcium hydroxide paste propylene glycol and normal saline.

According to making research on its deconstructing subject in the traditional philosophy, We can get a more profound understanding about the relationship between his philosophy and the traditional philosophy Wittgensteinian deconstructing mainly embodies the following points; firstly ,he unloaded magic halation of "self",according to researching 'self'; secondly , he removed the duality of subject .thirdly, he discarded introspection belonging to the subject.

后期维特根斯坦的哲学是以彻底反传统著称的，通过对后期维特根斯坦哲学对传统哲学中的"主体"的消解，我们能更深刻地理解他的哲学与传统哲学之间的关系。维特根斯坦的消解主要体现在三个方面：（1）通过对"我"的考察，卸掉了"我"身上的神秘光环；（2）解除了主体身份的二重性；（3）抛弃了主体的反思功能。
