In conclusion, features of morohopathology, IHC profile and ultrastructural findings reveal obvious divergence between CHP and HP and resemble MP, so we suggest that histogenesis of CHP is pericyte with myoid differentiation.

根据此研究之结果得知，无论在肿瘤发生部位、组织病理形态学、免疫组织化学染色结果以及超显微结构的特徵，CHP与HP具有明显的差异性，反而与MP之特徵较为相近，此结果可间接证实CHP之肿瘤细胞来源与MP的肿瘤细胞之来源较为相似，可能为血管周围细胞来源并具有类肌肉细胞的分化。

Then transplantation of the sciatic nerve from donor rats to the recipient rats in two groups were progressed.7 days after nerve transplantation,the contents of cd4 and cd8 in peripheral plasma of recipient rats were detected by flow cytometry.8 weeks after nerve transplantation,transplanted nerve were observed under light microscope.results:compared with nonirradiated group,the percentage of cd4 and the ratio of cd4 to cd8 in uvb irradiated group were significantly decreased（p＜0.05,p＜0.01）,cd8 percentage was significantly increased（p＜0.01）.conclusion:uvb-irradiated donor splenocytes were injected in the recipient rats through caudal veil,which could induce immunological tolerance to allogeneic transplantation.

未照射组注射未经紫外线照射的供体脾细胞，照射组注射经紫外线照射的脾细胞，7 d后移植供体神经。术后7 d行外周血t淋巴细胞亚群检查，术后8 w行移植神经组织学检查。结果：照射组cd4+百分率、cd4+/cd8+比值较非照射组明显降低（p.01，p.05），cd8+百分率较非照射组明显升高（p.01）。组织学检查显示，照射组的再生神经较非照射组多。结论：尾静脉内注射经紫外线照射的异基因脾细胞可诱导对异体神经移植的特异性免疫耐受。紫外线；脾细胞；免疫耐受；坐骨神经

免疫组织化学观察发现，产抗菌肽细胞在兔圆小囊的黏膜上皮、圆顶上皮以及淋巴组织的滤泡生发中心、圆顶区和帽区均有分布；在兔感染多杀性巴氏杆菌后，圆小囊及其他肠道组织中的抗菌肽免疫组织化学阳性细胞数量明显增多，阳性反应增强。

The results demonstrated that, by comparison with un-transgenic Roselle cell or callus, the critical plating cell density and critical initiating cell density of transgenic cell line were cut down 60% and 50%, respectively,the growth cycle of transgenic cell in suspension culture was shortened from 16 days to 12 days, and the specific growth rate of transgenic Roselle callus was raised 75%, the content of flavonoid compounds in transgenic Roselle cell line or callus was hardly altered.

研究结果表明，所获得的转基因玫瑰茄细胞系的临界植板细胞密度和临界起始细胞密度分别降低了60%和50%，悬浮细胞培养周期由16d缩短到12d，转化愈伤组织的比生长速率比对照提高了75%，转基因玫瑰茄细胞和愈伤组织中的花黄素含量与对照相比没有发生明显变化。

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。

The tumors ranged from 5.5 to 20 cm and had a characteristic histologic appearance with irregular, sharply circumscribed nests and islands of bland-appearing spindled to focally epithelioid cells, surrounded by a cellular desmoplastic stroma.

这9例肿瘤大小为5.5至20cm，瘤组织特征性地表现为：温和的梭形细胞至灶性上皮样细胞排列成巢或成岛，这些细胞巢团界限相当清楚但不规则，周围间质细胞丰富、促纤维组织增生性。

In both inflammatory and healthy gingival epithelium, CD14 mRNA positive cells, which are mainly located at thornlike cell layer, were found.

另一方面，牙髓组织除树突状细胞外CD14表达细胞很少，牙龈组织皮下的成纤维细胞和未分化细胞也不表达CD14。

In peripheral blood,〓increases, so cause 〓 balance is broken, and 〓 which can induce inflammatory reaction increases obviously too; meanwhile, there are immuno- function change in the red cells, the RBC-〓 receptor rosette promoting rate of serum decrease, indicate this uveitic animal model have both cellular immunity dysfunction induced by T cells and the changes of RBC immuno-function. The analysis of the local and systemic immuno-function changes of uveitic animal model offers objective theoretical bases for combining the local treatment and the systemic treatment.

葡萄膜炎兔房水中房水中〓及IL-2均升高，病变葡萄膜组织中T细胞表面分化抗原的免疫组化检查显示大量阳性细胞，表明兔葡萄膜组织本身存在着免疫功能亢进所导致的病理改变，而外周血中〓增高，导致〓平衡失调，介导炎症反应的〓亦明显增高，同时伴有红细胞免疫功能改变，外周血中RBC-〓受体花环率及血清中RBC-〓受体花环促进率均降低，显示葡萄膜炎兔本身既存在T细胞介导的细胞免疫反应功能紊乱，也存在红细胞免疫功能改变，这种局部和全身的免疫功能改变分析为葡萄膜炎的治疗局部和全身相结合提供了客观的理论依据。

Mouse fetal tissues could be cut into uniform small pieces by scissors cutting and needle grinding, which grew well in tissue culture and great amounts of cells grew from the attached small tissue clump to form primary mouse embryonic fibroblasts monolayer.
