摘要 目的:探讨环氧化酶2(COX-2)在肝衰竭损伤肝组织中的表达。方法:BALB/c小鼠随机分为正常对照组(n=6)和肝衰竭组(n=24),前者以生理盐水200μl腹腔注射,后者采用内毒素(LPS)10μg/kg和D-氨基半乳糖(-DGal)900 mg/kg联合腹腔注射,对照组在注射后8 h、肝衰竭组在注射后不同时点(2、4、68、h)检测血浆谷丙转氨酶(ALT)、谷草转氨酶(AST)、白介素10(IL-10)、肿瘤坏死因子α(TNFα)、细胞黏附分子1(ICAM-1);处死动物,以原位灌注消化法分离肝Kupffer细胞后,半定量RT-PCR检测其中COX-2 mRNA的表达。结果:与对照组相比,肝衰竭组血浆ALT、ASTI、L-10、TNFαI、CAM-1水平均显著升高(P<0.05),且随损伤时间的延长而逐渐升高(P<0.001);COX-2 mRNA仅在肝衰竭组表达,表达量随肝损伤时间延长也逐渐增高(P<0.001)。结论:COX-2在损伤肝组织中大量表达,且表达量随肝损伤程度而升高,提示其可能参与了LPS/D-Gal诱导的肝衰竭模型肝损伤过程。
