2、0只成年SD大鼠随机分成3组(一20):假手术组(sham组)、对照组(St.Thomassolution组,STS组)和实验组(PolyHb组)。利用Langendorff离体心脏灌流法,观察心脏在4℃含或不含PolyHb的St.Thomas液中保存8h复灌120rain心脏功能的变化情况,比较冠脉流出液中肌酸激酶(CK)和乳酸脱氢酶(LDH)的释放量和心肌梗死面积。结果与STS组比较,含PolyHb的St.Thomas液可增强再灌注时左室发展压(P3、和LDH的含量(P<0.0O1),减少心肌梗死面积百分比(P<0.001)。结论含PolyHb的St.Thomas液对低温保存8h后离体鼠心的缺血再灌注损伤有明显的保护作用。【关键词】聚合血红蛋白心脏移植器官保存缺血再灌注损伤【中图分类号】R654.1CardioprotectiveEffectsofSt.ThomasSolutionContainingPolyHbonIsolatedRatHeartDuringColdPreservationZHANGPu。LJTao。。LIUJin.1.DepartmentofPha4、rmacology&Biopharmaceutics,肌盯ChinaSchoolofPharmacy,SichuanUniversity,Chengdu610041,China;2.LaboratoryofAnesthesia&CriticalCareMedicine,WestChinaH05pital,SichuanUniversity,Chengdu610041,China△Correspondingauthor,E—mail:scujinliu@gmail.eom[Abstract]ObjectiveToinves5、tigatethecardioprotectiveeffectsofSt.ThomassolutioncontainingPolyHbonischemia-reperfusioninjurytoisolatedratheartaftereight—hourcoldstorage.MethodsSixtymaleinbredSDratswererandomlydividedinto3groups(一20ineachgroup):shamgroup,St.Thomassolution(STS)groupandSTSwithP6、olyHbgroup.TheLangendofisolatedratheartmodelwasused.Theheartswerestoredin4℃St.ThomassolutionwithorwithoutPolyHbfor8hfo/lowedby120minofrepefusion.Therecoveryofcardiacfunctionwasobserved.Myocardialenzyme1eakageandinfarctsizeweremeasuredafterreperfusion.ResultsIncom7、parisonwithSTSgroup,St.ThomassolutioncontainingPolyHbimprovedtherecoveryofLVDP(P8、oncanprotectmyocardiumfromischemia—reperfusioninjuryaftereight-hourcoldpreservation.[Keywords]PolymerizedhemoglobinHearttransplantationOrganpreservationIschemi
