摘要 目的探讨大鼠离体肝脏保存再灌注后肝脏组织中细胞间黏附分子-1(ICAM-1)mRNA的表达变化及丹参对其表达的影响。方法选取健康Wistar雄性大鼠54只,用完全随机方法选6只大鼠作为正常组,切除肝脏后立即灌注;随机选24只大鼠作为对照组,切除肝脏后置入4℃UW液中分别保存8、16、24、32 h后再行肝脏循环再灌注;余下的24只作为实验组,切除肝脏后置入含丹参的4℃UW液中分别保存8、16、24、32 h后再行肝脏循环再灌注。应用RT-PCR方法检测各组大鼠离体肝脏保存再灌注后肝脏组织中ICAM-1 mRNA表达。结果正常组肝脏中的ICAM-1 mRNA表达为3.61±1.56,对照组和实验组8、16、24、32 h时肝脏中ICAM-1 mRNA表达分别为15.71±1.78、33.70±3.35、45.83±4.37、66.98±5.89和11.69±1.25、16.55±1.37、24.73±2.74、32.65±3.39,对照组和实验组各时相均分别明显低于正常组(P<0.05),且均随保存时间延长,ICAM-1 mRNA表达逐渐增加(P<0.05),实验组16 h后ICAM-1 mRNA表达均分别明显低于对照组相应时相(P<0.05)。结论丹参能够降低离体肝脏保存再灌注后肝脏组织中ICAM-1 mRNA表达,对肝脏保存再灌注损伤可能具有防护作用。
