Control cells appeared to be mostly round,intact and bright green while a lot of the cells cultured with GM exhibited some irregular cell morphology ,with bright green or jacinth nuclei , Pyknosis and fragment appearance which characteristic apoptosis .

GM损伤组作用24小时后，可见较多的核着亮绿色或橘红色、呈固缩状或片段状的凋亡细胞，当时间延长到48小时，凋亡细胞进一步增多。

Abstract］ AIM:To investigate the role of nuclear factor κB in the induction of iNOS gene by TNFα and LPS in endothelial cells and the effect of antioxidant on the induction of iNOS. METHODS:Nitrite was determined based on Griess reaction. iNOS mRNA was analyzed using Northern blot. NFκB in the cell nucleole was detected with electrophoretic mobility shift assay.RESULTS:(1)NO production and iNOS mRNA expression induced by LPS and TNFα was blocked by pyrrolidine dithiocarbamate or N-acetylcysteine.

研究表明内皮细胞激活时iNOS表达的调控主要发生在转录水平。iNOS基因的启动子区域含有多个转录因子的结合位点包括NFκB、AP-1、NF-IL6，Oct-1等［2］，而核因子κB(nuclear factor κB， NFκB)被认为在多种参与炎症反应的蛋白质因子的基因调控中担任重要角色，因而可能是内皮细胞激活的调控中一个重要转录激活因子［2，3］。

结果 第6~7个月龄时，小脑室管层内可见NOS阳性神经元细胞，核多呈圆形，细胞有短小突起。

Results:17 rats were confirmed successful transplantation by MRI,the capacity of the tumor was 88.40±7.62mm3 on 8th day, 986.80±114.46mm3 on 16th day,the volume growth was 8-12 folds;on 8th day following transplantation,the tumor tissue was gray in color with fish homogen state without interior necrosis, the tumor cells were nest-distributed by HE staining,large dense staining of nucleus with manifest heteromorphism,tumor microvessel count increased by immunohistochemistry with buffy yellow staining, VEGF high expressed in the tumor cells with buffy yellow granule shape.

结果：17只大鼠经MRI检查证实均种植成功，肿瘤体积第8天为88.40±7.62mm3，第16天为986.80±114.46mm3，体积增长8-12倍之间；种植第8天，肿瘤组织呈灰白色、鱼肉均质状，内部未见坏死，HE染色肿瘤细胞呈巢状分布，胞核大浓染，异型性明显；免疫组织化学示肿瘤微血管数目较多，呈棕黄色染色，肿瘤细胞VEGF高表达，呈棕黄色细颗粒状。

Primary cultured chondrocytes are poly-angle, cytoplasm-rich, and their nuclei are either round or oval with clear necleole. Metachromatic and alcian blue positive staining in primary cultured chondrocytes was observed. Intercellular matrix was anti-collagen type Ⅱ staining but not anti-collagen type Ⅰ staining by IHC assay.
