大鼠移植肝保护管理论文 【摘要】目的探讨川芎嗪(TMP)对大鼠移植肝的保护作用。方法参照 Delriviere 和 Kamada 等方法建立大鼠肝移植模型,将大鼠随机分为 3 组:A 组(假手术组)、B 组(肝移植对比组)和 C组(TMP 干预组)。采纳全自动生化分析仪检测术后血清肝功能(AST、ALT、LDH)水平;应用免疫组化 SP 法结合病理图像分析仪测定肝组织中 Bcl-2、Bax 的表达情况;HE 染色观察其病理形态学变化。结果(1)C 组 AST、ALT、LDH 明显低于 B 组(P0.05)。(3)A 组无明显病理形态改变,B 组术后肝组织出现明显的病理损害,C 组病理变化明显减轻。结论 TMP 可能通过上调 Bcl-2 或 Bcl-2/Bax 表达而减轻肝移植体的低温保存再灌注损伤,对供肝有保护作用。 【关键词】肝移植;保存再灌注损伤;川芎嗪;Bcl-2;Bax Protectiveeffectoftetramethylpyrazineonlivergraftinratlivertransplantation 【Abstract】ObjectiveToinvestigatetheprotectiveeffectoftetramethylpyrazine(TMP)preconditioningonlivergraftinratlivertransplantation.MethodsPerformingtheoperationoflivertransplantationinmaleSprague-DawleyratsreferredtoDelriviereandKamadawithcuffanastomosingmethods,theratswererandomlydividedintothreegroups:Agroup(n=6,shamoperationgroup),Bgroup(n=30×2,livertransplantationcontrolgroup),Cgroup(n=30×2,TMPgroup).Theparametersofliverfunction(AST , ALTandLDH)weretestedbyauto-biochemicalanalyseringroupBandCafterreperfusion0.5h , 3h, 6h , 24h , 48hrespectivelyviatheplasmasamples ;partofthelivertissuewassampledtodeterminetheexpressionofBcl-2andBax.TheparametersingroupAwereexamed3haftertheoperation.TheexpressionofBcl-2andBaxwasdeterminedbyimmunohistochemistytechniquewithpathologicalimaginganalyser.Also , partsoflivertissuesampleswereusedtodetectthehistopathologicchanges.Results(1)ThelevelsofAST , ALTandLDHweresignificantlydecreasedingroupCcomparedwiththatingroupB(P<0.01)afterreperfusion0.5h,3h,6h,24h,48hrespectively.(2)TheexpressionofBcl-2weresignificantlyincreasedingroupCcomparedwiththatingroupB(P<0.01)afterreperfusion0.5h,3h,6hrespectively.ThedifferentexpressionofBaxbetwe...
