1、青岛大学硕士学位论文白矾保肝降脂方对非酒精性脂肪肝大鼠疗效机理的实验研究姓名:支晓丽申请学位级别:硕士专业:中西医结合临床指导教师:王者令20120602白矾保肝降脂方对非酒精性脂肪肝大鼠疗效机理的实验研究摘要目的:观察白矾保肝降脂方对非酒精性脂肪肝大鼠的治疗效果,并探讨该方的作用机理,从而为该方的临床应用提供实验依据。方法:将60只Wistar雄性大鼠随机分为白矾保肝降脂方组、保肝降脂方组、水林佳组、模型对照组和正常对照组,共5组,每组12只。除正常对照组外,其余各组采用高脂饲料喂养制备NAFLD大鼠模型,连续8周。8周末,各组给予相应药物灌胃,连续4周。末次给药后,称重大鼠及肝湿重,
2、计算肝脏指数;检测各组大鼠血清中ALT、AST和TC、TG的含量;ELISA法检测各组大鼠血清及肝组织中ADP、TNF—fl的含量;HE染色评价各组大鼠肝组织病理改变。使用SPSSl6.0统计软件对实验数据进行统计学分析。结果:1.与正常对照组比较,模型对照组大鼠肝脏指数、血清中ALT、AST和TC、TG的含量、血清和肝组织中TNF—Q的含量均明显升高(P均3、Q水平降低,使下降的ADP水平升高(P均<0.05)。3.各治疗组间疗效比较,在降低血清ALT水平方面,以水林佳组疗效最为显著;在降低血清TC水平方面,以白矾保肝降脂方组疗效最为显著,保肝降脂方组次之,水林佳组疗效最差;在升高肝组织ADP水平方面,两中药复方组疗效优于水林佳组。结论:白矾保肝降脂方具有多途径、多靶点治疗非酒精性脂肪肝的作用;白矾保肝降脂方可通过降低转氨酶、血脂及TNF—a水平,升高ADP水平,来减轻多因素导致的肝损伤,可能为该方治疗非酒精性脂肪肝的作用机理之一。硕士研究生支晓丽(中西医结合临床)指导教师王者令教授关键词:白矾保肝降脂方;非酒精性脂肪肝;实验研究Studyo4、ntheEffectsofAlumHepatoprotectiveDecoctiononNAFLDRatModelAbstractObjective:Toinvestigatetheeffectsofalumhepatoprotectivedecoctiontreatingthenon.alcoholicfattyliverdiseaseratmodelsandexploreitsactionmechanism.thellprovidethescientificexperimentalevidencesforitsclinicalapplication.Methods:60Wistarm5、aleratsWel'erandomlydividedintofivegroups:alhillhepatoprotectivedecoctiongroup,hepatoprotectivedecoctiongroup,silybiningroup,modelcontrolgroupandnormalcontrolgroup,eachgroupof12rats.Besideofthenormalcontrolgroup,othergroupswerefedthehighfattydietforcightweekstomakeNAFLDratmodels.Then.eachgroupwou6、ldbeintervenedrespectivelyforfourweeks.Afterthelastdruggiving,rats’bodyqualityandliverwetweightwereweighed,thentheliverindexwouldbecalculated:thecontentsofALT'ASTandTC,TGinratserumfromeachgroupweredetected:ELISAwasappliedtodetectthecontentsofADP’TNF.ainratserumandlivertissuefromeachgroup.HEmucuss7、tainwasusedtoobserveliverpathologicchangesfromeachgroup.Statisticalsoftware16.0wasemployedtomakethestatisticalanalysisforexperimentaldata.Results:1.Comparedwiththatofthenormalcontrolgroup.Theliverindex.thecontentsofAL,
