摘要 目的探讨右美托咪定预处理对小鼠缺血再灌注损伤后肝肾功能的影响。方法选取8周龄C57BL/6雄性小鼠24只,随机分为3组(n=8):正常对照组(Sham组)、缺血再灌注组(IR组)和右美托咪定处理组(IR+Dex组)。IR+Dex组小鼠于造模前25 min腹腔注射右美托咪定(50μg/kg),Sham组和IR组于造模前25min腹腔注射同等量的生理盐水,小鼠肾缺血再灌注模型建立成功后于再灌注24 h处死取材。分别取小鼠血清检测血肌酐(Scr)、尿素氮(BUN)、丙氨酸氨基转移酶(ALT)和天门氨酸氨基转移酶(AST)等肾功能及肝功能指标,取肾脏和肝脏组织匀浆液检测超氧化物歧化酶(SOD)、丙二醛(MDA)、肿瘤坏死因子-α(TNF-α)、白细胞介素-6(IL-6)、单核细胞趋化因子-1(MCP-1)和白细胞介素-10(IL-10)等指标。结果与Sham组比较,IR组小鼠血清中Scr、BUN、ALT和AST等指标含量明显升高(P<0.05);IR组小鼠肾脏、肝脏组织匀浆液中SOD明显降低(P<0.05),MDA、TNF-α、IL-6、MCP-1和IL-10明显升高(P<0.05);与IR组比较,IR+Dex组小鼠血清中Scr、BUN、ALT和AST等指标含量明显降低(P<0.05);IR+Dex组小鼠肾脏、肝脏组织匀浆液中SOD和IL-10明显升高(P<0.05),MDA、TNF-α、IL-6和MCP-1明显降低(P<0.05)。结论右美托咪定能明显减轻小鼠肾缺血再灌注致肾、肝损伤的程度,其机制可能与提高小鼠缺血再灌注后肾、肝的抗氧化能力,抑制氧自由基堆积有关。
