In this study, oral tolerance was induced by tube-feeding transgenic mice with 0.5mg/day OVA protein daily, simultaneously sensitized by OVA protein with aluminum hydroxide. Oral-administered OVA protein (0.5mg/day for 5 or 10 consecutive days) resulted in significant lowered airway hypersensitivity as well as reduced inflammative cells infiltration, titer of serum OVA-specific IgE, IL-5 secretion in bronchoalveolar lavage fluid, and IL-4 secretion in splenocyte.

3Rhe distribution and change of proliferating cell nuclear antigen in seminiferous tubule: The positive staining of proliferating cell nuclear antigen was found in slices of all groups, the immunological positive products were located at karyon, usually in brown yellow granules, only a small part of them in diffuse state; the immunological positive cells were mainly the spermospores, besides a small quantity were spermiocyte, supporting the cell and myoid cell nuclear to be stained.

3增殖细胞核抗原在生精小管中的分布及变化：各组切片均可见增殖细胞核抗原阳性染色，免疫阳性产物位于细胞核，通常呈棕黄色颗粒，小部分呈弥散状；免疫阳性细胞主要是精原细胞，另外还有少量初级精母细胞、支持细胞和肌样细胞核着色。

Therefore, the disruption of the actin cytoskeleton initiates a cascade of structural and functional alteration in renal epithelial cells and which will lead to the dysfunction of reabsorption in kidney.

肌动蛋白聚合形成了肾脏上皮细胞内对微绒毛起支撑作用的细胞骨架，因此肌动蛋白细胞骨架的破坏势必导致肾小管上皮细胞结构和功能的改变，从而引起肾脏的重吸收功能障碍。

Result: Schwann-like cells disperse in the hole of nerve graft at oneweek under Scanning Electronic Microscope, the processes of thesatellite-like cells adhere to the wall of graft.There was no statisticaldifference of activity of cells in both group(P＞0.05) using MTT. At 12weeks,the result of appearance, histology and TEM were similar, therewere no statistical difference in SFI%, NEP and quantitative analysis ofrecovery rate of myelinated fiber populations, diameter of myelinatedfiber and thickness of myelin sheat.

结果：1w后扫描电镜下可见接种的类Schwann细胞分散在材料表面的孔隙内，细胞形态为星状，细胞突起与支架管壁粘附；MTT法测定细胞活性示神经支架组在各时间点与对照组无显著性差异P＞0.05；12w时两组动物坐骨神经外观、组织学光镜观察、透射电镜观察结果相似、两组坐骨神经功能指数恢复率、神经电生理、再生有髓神经纤维计数恢复率、神经纤维直径恢复率、髓鞘厚度恢复率等指标相比无显著性差异(P＞0.05)。

The adipose derived stem cells of inbreds train of rat wereinduced to differentiate into schwann-like cells and the cells were injectedinto the acellular nerve allograff.The proliferation or adhersion of these cells on the graft were observed by inverted microscope or ScanningElectronic Microscope. Activity of cells were detected using MTT. 10mmnerve gap of inbreds train of rats in two group were bridged by tissue-engineered peripheral nerve or autogenous nerve, the effect wereappraised by naked eye, recovery rate of sciatic function index,nerve-electrophysiological, histology, Transmission ElectronMicroscopy and quantitative analysis of recovery rate of myelinated fiberpopulations,diameter of myelinated fiber and thickness of myelin sheat.

按照前述方法培养并诱导近交系大鼠脂肪干细胞向类Sehwann分化，将诱导分化的脂肪干细胞悬液注入已制备的去细胞同种异体神经支架管中，倒置显微镜观察细胞生长情况；扫描电镜下观察细胞在材料上附着情况；四唑盐比色试验测定细胞活性；取两组近交系大鼠，分别用组织工程化神经和自体神经桥接10mm神经缺损，通过大体观察、坐骨神经功能指数恢复率的测定、神经电生理的测定、组织学光镜观察、透射电镜观察、再生有髓神经纤维计数恢复率、神经纤维直径恢复率、髓鞘厚度恢复率的测定等指标评价实验效果。

Animals, as material, were used to study the toxicity of outer substance and made sure the estrogen effect of BBP by whole animal experiment, and the chronic toxicity of BBP was studied, designed and valued through several dosages and different exposed time. The result showed that BBP could make testis, epididymis and prostate withdrawl. Tectology changes were observed in testis, epididymis and liver. Especially the atrophy and degeneration of seminiferous tubules, decrease of spermatogenic cell and the turbulence of Sertoli cell and spermatogenic cell of seminiferous epithelium were also observed. The linkage between cells vanished.
