2、大鼠随机分为对照组、模型组和给药组,每组2O只,以铜负荷饮食法造模8周,造模第4周后给药组给予EMD、RTP各200mg/(kg·d)灌胃,对照组和模型组给予等量生理盐水,各组共灌胃4周。观察各组大鼠血清和肝组织丙二醛(MDA)、超氧化物歧化酶(SOD)和谷胱甘肽过氧化物酶(GSH—Px)水平和肝功能指标的变化。结果与对照组比较,模型组血清和肝组织中MDA水平显著升高,SOD、GSH—Px水平显著下降(P3、)水平显著下降(P<0.01)。给药组较模型组血清和肝组织中MDA水平显著下降,SOD、GSH—Px水平显著升高(P0.05)。结论EMD联合RTP能抑制铜负荷模型鼠体内脂质过氧化,改善其肝功能水平。[关键词]大黄素;大黄多糖;肝豆状核变性;铜负荷;脂质过氧化;肝功能EffectofEmodinandRheumTanguticumPolysaccharideonLipidPeroxidationinCopper-Over4、loadedRatsXUlei。CAIYongliang,WANGYanxin,H0UZhifeng,ZHUHong(TCMHospitalofAnhuiProvince,AnhuiProvince230031)ABSTRACTObjectiveToresearchtheeffectofEmodin(EMD)andRheumtanguticumpolysaccharide(RTP)onlipidper—oxidationandliverfunctionincopper-overloadedrats.MethodsSixtyWistarratswerera5、ndomizedintothecontrolgroup,modelgroupandtreatmentgroup,with20ineach.Theratmodelswereestablishedwithcopper—overloadeddietforeightweeks.Thetreatmentgroupwasintragastricallyadministratedwith200mg/(kg·d)EMDandRTP.Theothertwogroupsweregivennormalsaline.Thetreatmentlastedforfourweeks.6、Thelevelsofmalondialdehvde(MDA),superoxidedismutase(SOD),glutathioneperoxidase(GSH—Px),alanineaminotransferase(ALT),aspartateaminotransferase(AST),totalbiliru—bin(TBiL)andalbumin(ALB)Wereobserved.ResultsComparingwiththecontrolgroup,thelevelsofMDA,ALT,ASTandTBiLweresignificantlyin7、creased(P8、mentgroup.Therewasnosignificantdifferenc
