摘要 目的探讨前列腺素E1对梗阻性黄疸肝缺血再灌注时肝组织细胞间黏附分子-1(ICAM-1)表达的影响。方法雄性Wistar大鼠随机分为前列腺素E1组(PG组)和生理盐水对照组(NS组),每组18只。结扎并切断胆总管建立梗阻性黄疸模型,7d后Pringle法阻断肝门15min,再灌注后建立胆道再通。于缺血前15min至再灌注60minPG组按0.5μg/(kg.min)经门静脉持续泵入前列腺素E1,NS组给予等量生理盐水。分别于再灌注1,6,24h三个时点取材,检测血清ALT、AST和总胆红素水平,免疫组化法测定肝组织ICAM-1表达水平。结果再灌注各时点PG组血清ALT和AST水平以及肝组织ICAM-1表达水平均显著低于NS组(P<0.05),但两组总胆红素水平差异无统计学意义(P>0.05)。结论前列腺素E1下调肝组织ICAM-1表达,对梗阻性黄疸肝缺血再灌注损伤具有保护作用。
