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。

This study that observed the expression and distribution of 4 apoptotic factors, relation apoptotic factor with apoptosis, changes of T and B subgroup, and changes of molecular pathology in 14 cows suffering from enzootic bovine leucosis from several resides was detected by histochemistry, TUNEL technology, immune-fluorescent flow cytometry and so on. The aim of this experiment supplies theoretic basis for preventive and therapy of EBL, and consult dates for T lymphoid cell leucosis of human being .

本研究检查并剖检了14例临床与实验室诊断为EBL的病牛，观察分析了肿瘤发生的情况和特征，采用免疫组织化学ABC法、原位末端标记TUNEL技术和免疫荧光流式细胞检测法等技术，从EBL肿瘤细胞凋亡特性入手，围绕4种凋亡因子和几种免疫相关因子与EBL肿瘤发生的关系及其在诊治方面的应用进行了首次有价值的探索，其目的在于为防治EBL提供科学的理论依据，同时，也将为人类T细胞白血病Ⅰ。

Methods The LPL cDNA was isolated from the human epiploon adipose tissue by means of RT-PCR. The LPL cDNA was ligated into the pcDNA3.1Zeo. The recombinant pcDNA3.1Zeo-LPL cDNA was identified by endonucleases, PCR and DNA sequencing. COS-1 cells were transfected with the recombinant LPL gene plasmid using Lipofectamine 20001M The LPL mass in cells and the culture medium were determined by a Markit-M LPL Kit. Spectrophotometry was used to measure the LPL activity.

In 1988 a lacrimal gland tumor was incompletely removed from the left orbit of a 36-year-old woman and diagnosed as "solid basaloid adenoid cystic carcinoma". Soon after, an exenteration of the orbit was performed. In 1998, upon review of the initial histopathology, the diagnosis of solid adenoid cystic carcinoma was changed to basal cell adenocarcinoma..

方法；1988年一个36岁的妇女的泪腺肿瘤从左眼眶不完全摘除，诊断为"实质性基底细胞囊腺癌"，不久进行了眼眶内容去除术。1998年对原始的组织病理学进行回顾，实质性基底细胞囊腺癌被更正为基底细胞腺癌。
