OVCs were isolated by density ladder centrifugation in the 4th week, and then OVC's morphology was observed under transmission electromicroscrope and immunocytochemistry were performed to detect the expression of ICAM-1. Results Observing OVC's morphology under transmission electromicroscrope showed that OVC was infantile and undifferentiated with big nucleus, clear nucleolus, large nucleoplasm-ratio, small mitochondria, and little endoplast.

结果 透射电镜下观察到OVCs超微结构的改变为核大，核/浆比大，核仁小，胞浆内细胞器少，可见少量内质网和小线粒体，整个细胞呈幼稚、未分化状态；ICAM-1免疫细胞化学检测阳性；损伤肝组织HE染色和ICAM-1免疫组化检测显示，肝损伤初期，Hering管周围OVCs增生并且ICAM-1阳性表达，随着肝损伤的加重，OVCs继续增生，并且，OVCs沿增生的肝纤维向肝小叶迁移，同时，ICAM-1阳性表达也继续增多，并逐渐向肝小叶弥散分布；透射电镜下观察到，肝损伤初期，OVCs在Hering管周围增生，肝纤维随之增生，增生的OVCs与肝纤维黏附生长。

The plasticity of NSCs was detected by the differentiating test. HESCs were induced into dopaminergic neurons by means of adding Sonic Hedgehog Peptide and fibroblast growth factor eight (FGF8) early under the condition of mocked microenvironment and different development stage of dopaminergic neurons in vivo ,meanwhile made comparison with traditional method . The marker of dopaminergic neurons was tested by immunocytochemistry and RT-PCR, the content of dopamine and its derivation homovanillic acid were measured by HPLC-ECD.

He experiment results indicate that (1) The extract of Rubia Cordifolia L has the effects of anti-proliferation and inducing APO;(2) Whenadministrating with 5-fu, the extract of Rubia Cordifolia L obviously enhanced the effects of anti-proliferation and inducing APO of 5-fu;(3) The basement of molecular biology of the extract of Rubia Cordifolia L for inducing APO of MGC-803 cells is correlated with inhibiting the expression of bcl-2 of anti-apoptosis gene.

UNEL法与PCNA的免疫细胞化学法的结果：0.2、0.4、0.8、1.0mg/ml浓度的茜草提取物与2、4、8、16μg/ml浓度的5-Fu，分别诱导细胞凋亡和抑制细胞增殖，表现出浓度、时间依赖性关系，除个别浓度与个别时间之间无显著性差异（P＞0.05）外，不同浓度与不同作用时间之间均有显著性差异（P＜0.05或P＜0.01），并且两种药物联合使用时，MGC-803细胞的APO%显著提高，降低PCNA的阳性表达率（P＜0.05或P＜0.01）。

Based on establishment of the human macrophage-derived foam cell model, the expression of Kv1.3 channel was investigated by immunocytochemical staining, reverse transcription-polymerase chain raction and Western blot. Furthermore, the effects of rMargatoxin, a Kv 1.3 channel-specific inhibitor, on cholesterol metabolism in macrophages incepting oxidized low density lipoprotein were studied.
