2、素治疗组、肾病苯那普利治疗组。肾病组予阿霉素5mg/kg尾静脉注射一次,正常对照组予等量生理盐水尾静脉注射,注射后2周24小时尿蛋白定量>30mg为肾病模型成立。肾病激素治疗组与肾病苯那普利治疗组每日分别予强的松lOmg/kg、苯那普利3mg/kg灌胃,共4周;实验4周时留24小时尿蛋白定量及血生化,将所有大鼠处死,取肾脏皮质抽提总RNA和总蛋白,分别应用半定量RT-PCR和Western蛋白印迹法(Westernblot)测定podoeinmRNA和蛋白质的表达。结果:正常对照组大鼠podocin蛋白表达的相对量是5.26±1.19,而肾病对照组大鼠podocin蛋白基本不表达,肾上腺
3、糖皮质激素、苯那普利可增加podocin蛋白的表达;正常对照组、肾病对照组、1肾病激素治疗组、肾病苯那普利治疗组podocin分子mRNA的相对值分别为1.06±O.19、1.96±0,98、1.31±O.24、2.46±1.49,肾病对照组大鼠podocinrnRNA的表达与正常对照组相比显著上调(P4、肾病综台征可能是通过改变肾小球滤过膜分子结构而产生疗效。关键词:阿霉素肾病大鼠肾病综合征podocin基因表达糖皮质激素苯那普利精品参考文献资料优秀毕业论文盔丝匡盘盘主题±生焦硷立ExpressionsofPodocinmRNAandProteininGlomerulusofAdriamycin—inducedNephropathicRatsandtheEffectsofDrugsABSTRACTobjective:Toinvestigatethepossibleroleofpodocininproteinuriaandtheeffectsofglicocorticoidsandbena5、zeprilontheexpressionsofpodocinmRNAandproteininAdriamycin—inducednephropathicrats.Methods:Theratswererandomlydividedintofourgroups(normalcontrolgroup,nephropathycontrolgroup,glicocorficoids—treatedgroupandbenazepril·treatedgroup).ADR(5mg/kg)wasintravenouslyadministeredtothenephropmhygroup,whileSa6、lineWasintravenouslyadministeredtothenormalcontrolgroup.Twoweeksaftertheadministration,thenephropathicmodelof24一hourproteinurinequantity>30ragwasformed.Prednisone(10mg/kg)andbenazepfil(3mg/kg)wereorallyadministeredtotheglicocorticoids-treatedgroupandthebenazepril—treatedgrouprespectively.Fourweek7、saftertheadministration,urinaryproteinandbloodwerecheckedandtheratswerethenkilledtoacquiretherenalcodexfromwhichthetotleRNAandproteinweredrawn.TheexpressionsofpodocinmRNAandproteinweremeasuredwiththesemi—quantityRT-PCR
