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。

Lyell and Hooker agreed that a joint paper should be presented at the Linnean Society, and on 1 July 1858, the papers entitled On the Tendency of Species to form Varieties; and on the Perpetuation of Varieties and Species by Natural Means of Selection, by Wallace and Darwin respectively, were read out but drew little reaction.

Holding the bow is like a teeterboard supported by thumb as the pivot and the cooperated forcing of forefinger and little finger produces a moment M. The "P-x-M Line Method" shows when playing a down bow, M increases with x and gradually changes its direction and this process is determined by P, the gravity and barycenter of bow. The "P-x-F Plane Method" shows that the most force-saving bowing path should locate in the lower part of this plane. The analyses of "Helmholtz Motion" and "Schelleng Diagram" indicate P and its range is in direct ratio with volume, velocity of bow, the approaching degree of the bow to the bridge and has some relationship with the quality of string and bow.

国内近期出现了用物理模型来研究小提琴运弓问题的尝试本文第一部分首先指出握弓类似于一个以***(F3)为支点的跷跷板，主要以食指(F1)和小指(F2)的施力配合，产生握弓力矩M；随后用"P-x-M直线法"证实：演奏下弓是M随的***而逐渐增大并转换方向的***，此***取决于P、弓的重力和重心；并首创"P-x-F平面法"，在x，F1，F2空间中证实：省力的运弓路径应在该平面中处于较低的位置第二部分通过分析"赫尔姆霍茨运动"和"Schelleng图表"指出：P及其变化范围和音量、弓速、弓与琴码的接近程度成正比，并与琴弦和弓自身的性质有关
