摘要 目的探讨氟比洛芬酯预先给药对大鼠肝脏缺血再灌注损伤的影响。方法健康雄性SD大鼠48只,体重250~300g。随机分为假手术组(S组)、缺血再灌注组(I/R组)和氟比洛芬酯预先给药组(FB组),每组16例。I/R组和FB组参照Nauta法建立肝脏部分缺血再灌注损伤模型,左、中肝叶缺血60min,再灌注6h。S组仅分离血管。FB组在缺血前15min自尾静脉注射氟比洛芬酯10mg/kg,I/R组自尾静脉注射等容量的0.9%氯化钠溶液。再灌注6h后经腹主动脉采血3ml,并切取肝组织。检测血清丙氨酸氨基转氨酶(ALT)含量和透明质酸(HA)含量,肝组织的MDA含量和SOD活性,肝脏标本的肿瘤坏死因子-α(TNF-α)的表达和核因子-κB(NF-κB)的表达,在电镜下观察由伊红(HE)染色的肝组织的形态学改变。结果与S组比较,I/R组肝组织的ALT、HA及TNF-α水平、MDA含量、NF-κB表达升高,SOD活性下降(P<0.05);与I/R组比较,FB组ALT、HA及TNF-α水平、MDA含量、NF-κB表达降低,SOD活性增高(P<0.05)。结论氟比洛芬酯预先给药可以降低对大鼠肝脏缺血再灌注损伤的影响。
