1、·820·ChineseHepatology,Dec.2013,Vo1.18,No.12·论著·大鼠慢加急性肝功能衰竭模型的制备谭晓慧薛璐瑜周跃汤伟【摘要】目的探索建立大鼠慢加急性肝功能衰竭模型的方法。方法SD大鼠40只,随机分为正常对照组、模型1组、模型2组和模型3组,每组各1()只。模型1组:每周二、五腹膜内注射4OCCI1mL/kg;持续4周;模型2组:每周二、五腹膜内注射4()/0CC11mL/kg,每周三腹膜内注射猪血清0.5mI,持续4周;模型3组:每周二、五腹膜内注射40CC1。0.7mL/
2、kg,每周三腹膜内注射猪血清0.3mL,持续4周,以5乙醇代水,自由饮用;正常对照组:不注射任何药物。实验第29天,各模型组大鼠均腹膜内注射脂多糖(LPS)30t~g/kg+D一氨基半乳糖(D-Ga1)0.3g/kg。以全自动生化分析仪检测大鼠血清ALT、AST和TBil水平。肝组织切片HE染色后光学显微镜镜下观察病理学变化。结果造模4周后各模型组大鼠血清ALT、AST和TBil水平均明显高于正常对照组(均P3、D—Gal后24h,模型3组中有3只动物死亡,3个模型组大鼠的ALT、AST和TBil水平均较注射前明显升高(均P<0.03),3组间差异均有统计学意义(均P<0.01)。注射LPS+D—Gal后72h,各模型组大鼠AIT、AST和TBil水平均较前明显降低(均P<0.01),但仍明显高于正常对照组(均P<0.O1),3组间差异仍均有统计学意义(均P<0.01)。注射LPS+D-Gal后24h,肝窦明显扩张、充血,大量炎性细胞浸润于汇管区,小叶内见肝细胞坏死。结论采用40CC1+猪血清诱导慢性肝损伤后,再4、以LPS30~g/kg+D—Gal0.3g/kg攻击,可成功制备大鼠慢加急性肝功能衰竭模型。【关键词】慢加急性肝功能衰竭;四氯化碳Anapproachforbuildingamodelofacuteonchronicliverfailureinrat了’ANXiaohui。XUELuyu。ZHOUYue.TANGWet.DepartmentofInfectiousDisease,AffiliatedHospitalofNantongUniversity,Nantong226001,ChinaCorrs。卯5、dgauthor:TANGV,tdfy16302@163.cowl[Abstractl0bjectiveToexploreanapproachforbuildingamodelofacuteonchronicliverfailure(ACLF)inrat.MethodsFortySDratswererandomlydividedintonormalcontrolgroup,modelgroup1,modelgroup2andmodelgroup3,10ratsforeachgroup.Intraperit6、onealinjection(ip)for40carbontetrachloride(CC1)1mL·kgwasperformedforratsingroup1,2and3atthe2ndand5thdayseveryweektotallyfor4weeks,respectively.Additionalipforporcineserum0.5mLor0.3mLwasperformedforratsingroup2or3atthe3rddayeveryweektotallyfor4weeks,respec7、tively.Allratsinmodelgroupsdrank5ethanolfreelyinsteadofwater.Notanydruginjectionwasperformedforratsinnormalcontrolgroup.Atthe29thday,lipopolysaccharide(LPS)30g·kg一plusD-galactosamine(D-Ga1)0.3g·kg一ipwereperformedinallrats.Serumalanineaminotransferase(ALT)8、,aspartateaminotransferase(AST)andtotalbilirubin(TBI)levelweredetectedbytheautomaticbiochemicalanalyzer.Preparationoflivertissuesections,HEstainingandpathologicalchangeswereobservedbymicroscope.Results(1)After4weeks
