2、造模前28d给予参希胶囊(0.75g/kg)灌胃,余组给予等体积的生理盐水灌胃。分别于造模后6h行超声心动图测定心功能,检测心肌TNF—Q、II一18和MDA的含量,测定SOD的活性。结果与对照组比较,模型组小鼠的左室射血分数(EF)和短轴缩短率(FS)明显降低(Pd0.05),参希预处理显著提高内毒素血症小鼠的EF和FS值(Pd0.05);与对照组比较,模型组小鼠心肌TNF—Q、IL一1p和MDA含量升高,SOD的活性降低(P<0.05),参希预处理显著减少内毒素血症小鼠心肌TNF—d、IL1B和MDA含量,提高SOD的活性(P3、论参希胶囊对内毒素血症小鼠心脏具有保护功能,其可能与降低心脏炎症因子水平和氧化应激反应有关。关键词:内毒素血症;心肌损伤;炎性因子;氧化应激中图号:R285.5文献标志码:A文章编号:1672—0482(2015)O3—0258—03DoI:1O.14148/.issn.1672-0482.2015.0258ProtectiveEffectofShenXiCapsuleonEndotoxemiainMiceHeartZHUMing—hui,HUANGLi—bing。,ZHUJuan,ZHOUYu—di,ZHENGManf1.TheFirstCli4、nicalMedicalCollegeofNanjingUniversityofChineseMedicine,Nanjing,210023,China2.WheA/.1ilatedHospitalofNanjingUniversityofChineseMedicine,Nanjing,210029,China)ABSTRACT:OBJECTIVEloexploretheprotectiveeffectso±shenxlonheartinendotoxemicmice.METH0DSI、heexperi—mentalmicewereequally5、andrandomlydividedintocontrolgroup,I.PSgroup,shenxigroup,shenxi+IPSgroup.Theendotoxemiamodelwasestablishedbyintraperitoneal1yinjectingLPS.Miceingroupsshenxiandshenxi--LPSwereintragastrical1yadministeredwithshenxisolution(0.75g/kg),whilethesamedoseofnormalsalinewereintragastri6、cal1yadministratedinCOntrolgroupandIPSgroup.Theheartfunctionwasdetectedwithechocardiography,andTNF—a,II一1t?,MDA,SODinmyocar—dialtissuewasestimated6hoursafterLPSadministration.RESULTSComparedwithcontro1group.LPStreatmentcouldre—sultindecreasedmyocardia1activitiesofSOD,andeleva7、tedlevelsofTNF—a,II一1G,MDA(P<0.05);shenxitreatmentcouldimprovetheaboveaberrantindices.Comparedwithcontrolgroup,LPStreatmentcouldresultinreducedcardiacfunction,whileshenxitreatmentcouldimproveit.CONCLUSIONShenxishowsagoodcardio—protectiveeffectonthecardiacinjuryinendotoxemicmi8、ce,whichmaybereachedbysuppressinginflammatoryinfiltrationandoxidativ
