2、、中5.2g/(kg·d)、低2.6(kg·d)剂量组和科索亚组5.21(kg·d),另设正常对照组。模型组灌服同等体积的生理盐水,每天上午灌胃1次,连续用药8周。正常对照组不做任何处理。8周后检测心衰大鼠心脏超声指标、心肌重构指标。同时采用H—E染色观察心肌形态结构变化。结果与模型组比较,益心泰低、中、高剂量组和科索亚组LVIDs、LVIDd均显著降低,LVEF、LVFs显著升高(P3、心衰大鼠的心肌重构和心功能.延缓心衰的进展。[关键词]益心泰;慢性心力衰竭;心肌重构;心功能(中图分类号3R285.5,R541.6[文献标识码]A[文章编号]doi:lO.39696.issn.1674—070X.2014.07.005.023.04EfectofYixintaionMyocardialRemodelingandHeartFunctioninRatswithChronicHeartFailureWUHuatang1,WUGangqiange,SHENSiI,MAOXiangping~,LIUWenpin3,FANHonghuifJ.DepartmentofGe4、rontology,theFirstAffiliatedHospitalofHunanUniversityofChineseMedicine,Changsha,Hunan410007,China;2.HunanUniversityofChineseMedicine,Changsha,Hunan410007,China,"3.TheSecondAfiliatedHospitalofHUCM,Changsha,Hunan41000ZChina)[Abstract]ObjectiveToexploretheefectofYixintaionmyocardialremodelingan5、dheartfunctioninratswithchronicheartfailure.MethodsAratmodelofchronicheanfailurewasinducedbycoronaryarteryligationin.Thenthemodelratsweredividedequallyintofivegroups:modelgroup,high-dose10.4g/(kg·d),middle—dose5.2g/(kg·d),low-dose2.6g/(kg。d)ofYixintaigroupsandCozaargroup.Thenormalcontrolwasa6、lsodesigned.Themodelgroupwas[收稿日期]2014—05—13[基金项目]湖南省科学技术厅科技计划重点项目(2012FJ6051)。(作者简介]吴华堂,男,医学博士,副主任医师,主要从事老年病中医药防治研究。湖南中医药大学学报2014年第34卷receivedanequalvolumeofsalinebygavage.Themedicationwasgivenoncedailyineachtreatedgroupfor8weeks,thenormalcontrolgroupreceivednomedication.Echocardiographicin7、dicesandmyocardialremodelingindexwasmeasuredbyechocardiographyafter8weeksofmedication.MealwhileweadoptedH—EandMassionstainingtoobservethemorphologychangesofleftventricularmyocardium.ResultsComparedwimthemodelgroup.theLVIDsandLVIDdofhigh—dose,middle
