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. In initial stage of damaged liver, OVCs and the expression of ICAM-1 mostly distributed around Hering duct, and then gradually increased and expanded toward hepatic lobule, shown by staining paraffin sections with HE, immunochemistry and transmission electromicroscrope. Immunocytochemistry indicated that ICAM-1 expression on OVCs was positive.

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。

TheJiyang depression located in paleomonsoon climate zone in the period of the sahejieformation sedimentation, the wet and hot climate made ancient lake become deeperwater, enhanced stratification, reduced primary productivity of plankton, decreasingsedimentary velocity of carbonate, increasing sedimentary velocity of clay, fortifiedreductibility on certain degree, and then would be available for development of blackshale, dark shale and oil shale; In the contrast, the cold and dry climate lead ancientlake to shallower water, subdued stratification, increaser primary productivity ofplankton, enhancive sedimentary velocity of aphanitic carbonate, decreasedsedimentary velocity of clay, and then would be available for development calciteshale, calcite laminar shale, calcite mudstone, shaly carbonate rock, even laminarcarbonate or dolomite rock.

济阳坳陷在古近系沙河街组沉积期属于古季风气候带，在湿热的气候条件下古湖水加深，分层性增强，浮游生物的古生产力降低，隐晶碳酸盐的沉淀速率变小，粘土沉积速率加快，还原性一定程度上有所加强，有利于黑页岩、油页岩和暗色泥岩的形成：而相对干冷气候下，古湖水变浅，分层性减弱，浮游生物的古生产力增高，隐晶碳酸盐的沉积速率变大，粘土的沉积速率减慢，有利于钙质页岩、钙质纹层页岩、钙质泥岩、泥灰岩甚至纹层状碳酸盐岩、灰岩的发育。
