The periostea of both experimental and control side of the mandibular ramus were taken and prepared, 2 of each 5 rabbits in a group were prepared for HE stain detection and 3 for proliferating cell nuclear antigen immunohistochemical detection.Results:1, The newly formed bone was detected on the lateral aspect of mandibular ramus after periosteal distraction. The bone was shaped like a hill. It looked very low and was full of holes at postoperative day 28. With the time of consolidation period lengthened, the newly formed bone matured gradually. X-ray examination showed the new bone shaped like a hill. The average values of new bone height at postoperative days 28,35,42 and 56 were 1.86 + 0.15mm, 2.29 + 0.29mm,3.19 + 0.13mm and 4.70 + 0.45mm. Histological examination of both HE stain and picricacid-fuchsin stain showed the increase in the number of osteoblasts and the change in the orientation of collagen fibers and bone trabecula. There were no significant differences between newly formed bone and original bone on the lateral aspect of mandibular ramus at postoperative day 56 histologically.2 Compared with the control side, the distracted periostea proliferated obviously under the microscope, and the number of periostealcells increased with satiation of cellular nuclear per unit area. The images of PCNA immunohistochemical stain of periosteum showed that the experimental periosteum proliferated obviously after distraction compared with the control side.

结果：骨膜牵张成骨的实验研究南京医科大学硕{学位论文l、骨膜牵张后，可见下领升支外侧的骨皮质上有新骨形成，新骨呈山峰状凸起，术后第28天的新生骨较低平，多孔隙，随着固定时间的延长，新骨逐渐成熟；下领升支前后向切线位X线投照显示新骨呈山峰样隆起；经测量，术后第28、35、42和56天组平均新生骨厚度分别为x.86士0.15mm、2.29士0.29mm、3.19士0.13mm和4.70 土0.45mm；脱钙骨组织的HE染色和不脱钙骨组织的苦味酸一品红染色的组织学观察均显示了新生骨在成骨细胞数量上的增长，以及胶原纤维和骨小梁排列方向上的变化，术后第56天的新生骨在组织学上与原升支骨组织已无明显区别。2、HE染色显示，与对照组相比较，实验侧骨膜增生明显，细胞间排列紧密，单位面积内骨膜细胞数增多，细胞核饱满；骨膜PCNA 免疫组化染色显示，与对照侧相比较，实验侧骨膜在牵张后出现了明显的增生迹象，PCNA阳性细胞分布紧密，单位面积内阳性细胞数较对照组多，靠近骨表面的骨膜中的阳性细胞数更多而且分布更为紧密。

Objective: To investigate specific antitumor immune responses induced by autologous peripherial blood mononuclear cells from patient with gastric cancer pulsed with antigen GST-MAGE-3 in vitro.

The liver specimens were immunohistostained by SP method (1)Fas antigen and FasLs specific positive signals were found mainly on the surface or/ and in the cytoplasm of the hepatocytes, these positive hepatocytes were scattered nearby periportal region and hepatic lobule with piecemeal necrosis, the infiltrating lymphocytes were mainly FasL-positive cells.

1Fas、FasL在肝组织肝细胞膜及胞浆均有不同程度表达，其表达阳性细胞主要位于汇管区小叶内及周边碎屑状坏死区，呈弥漫分布，在其周围浸润的淋巴细胞上多为FasL阳性细胞，亦可见到Fas阳性细胞。

Objective: To investigate the clinical significance of detecting cancer antigen (CA125) in peritoneal dialysis patients.

目的：探讨癌抗原125(CA125)检测在腹膜透析中的临床意义。

The vein grafts with perivenous support by fibrin glue demonstrated a statistically decrease in neointimal and medial hyperplasia compared with non-supported vein grafts（p.01）. immunohistochemical analysis showed that the expression of proliferating cell nuclear antigen was inhibited significantly in fs group compared with ns group. almost intact endothelium was showed in fs grafts（p.01）. but in ns grafts there were severe endothelium damages where lymphocytes infiltrated. in ns grafts, the smooth muscle cells were hyperplasia and migrated to intimal, whereas in fs group, the hyperplasia of smooth muscle cells were inhibited and migrated to adventitia.

免疫组化结果显示与ns组相比，fs组移植静脉细胞增殖核抗原表达明显受到抑制；ns组内皮层损伤严重，有淋巴细胞侵润，而fs组内皮层则几乎完好无损（p.01）；在ns组平滑肌细胞增殖活跃且向内膜迁移，fs组平滑肌细胞增殖受到抑制，且向外膜迁移；在fs组移植静脉外膜有丰富的成熟微小血管网形成，但是在ns组，微小血管数量则非常少。
