目的:探讨二氮嗪(diazoxide,DA)预处理对大鼠部分肝移植的保护作用,寻找减轻临床部分肝移植中缺血再灌注损伤的途径。方法:将150只SD(Sprague-Dawley)大鼠,随机配对成75对,分为3组:对照组(C组)、DA预处理组(DA组)和5-羟基癸酸盐(5-hydroxydecanoate sodium salt,5-HD)+DA预处理组(HD-DA组),每组25对。在进行60%比例部分肝移植术前,C组供体不进行药物预处理;DA组供体在术前30min腹腔注射DA(5mg/kg);HD-DA组供体在术前45min腹腔注射5-HD(5mg/kg),并在其后15min腹腔注射DA(5mg/kg)。各组分别在术后2h、1d、3d、5d和7d各处死5只受体大鼠,测定谷酸丙氨酸转移酶(alanine aminotransferase,ALT)和门冬氨酸氨基转移酶(aspartate aminotransferase,AST),并在光镜下进行病理检查,电镜下进行超微结构检查。结果:DA组与C组相比,肝细胞肿胀、变性、坏死和空泡样变性以及肝小叶结构排列紊乱和汇管区炎症都较轻,而HD-DA组则跟与C组相近。DA组术后2h、1d、3d的ALT值和AST值均显著低于C组(P0.05)。结论:二氮嗪预处理对大鼠部分肝移植具有保护作用,但这种保护作用可以被5-羟基癸酸盐特异性阻断。
