    重庆医学000408摘 要:目的探讨ICAM-1和E-selectim在急性胆管炎肝损害中的作用。方法应用组织学方法观察ICAM-1和E-selectin对肝组织PMN浸润及其肝损害作用的影响。结果急性胆管炎时PMN在肝窦及肝细胞周围大量聚集,大鼠肝细胞变性坏死,动物12小时存活率仅为56.6%。抗ICAN-1及E-selectin单抗预处理使肝组织PMN数量明显减少,肝坏死面积减少,动物存活率提高。结果ICAM-1和E-selectin在胆道感染时肝组织PMN浸润及其肝损害过程中发挥重要作用。

    Abstract:AimH&Methods:The effects of ICAM-1 and E-selectin on PMN accumulation in liver and hepatic damage were investigated.Results: It was found that PMN accumulated in hepatic sinusoids and around hepatocytes, necrosis of the hepatocytes took place, and only 66.6 % of rats survived 12 hours after infection. Pretreatment of anti ICAM-1 and E-selectin mAb decreased the number of PMN in hepatic sinusoid and near hepattocytes, decreased necrosis of the hepatocytes, and improved survival rate of the infected rates. Conclusion: The results suggest that ICAM -1 and E-selectin play an important role in PMN accumulation and hepatic damage in acute cholangitis.
