2、精性脂肪肝模型;分别检测肠道细菌移位率(ST)和肠黏膜通透性[以乳果糖(L)/甘露醇(M)排出率(L/M%)表示]。同时观察血生化、肝脏和末段回肠黏膜病理学改变。结果在实验5w末,模型组大鼠肝组织呈中度脂肪变和炎症改变,其BT、L/M比值、碱性磷酸酶(ALP)和肝质量指数分别为70.0%、(0.38±0.18)%、(427.1-4-126.6)IU/L和(4.3±0.6)%,均显著高于对照组[(分别为10.0%、(0.23±0.07)%、(306.4.4-67.1)IU/L和(3.6±0.4)%,P<0.05)];与模型组比,各剂量化滞柔肝颗粒处理动物肝组织
3、小叶内炎症减轻,小剂量组UM和肝质量指数分别为(O.27±0.06)%和(3.8±03)%,均低于模型组(P4、.2)IU/L,也均低于模型组[分别为70.O%、(54.1±17.2)U/L、(163.2±67.5)U/L、(427.1±126.1)IU/L,P5、ranuleinratswithalco-holicfattyliverdiseaseLiXiaomei,SunBaocun,LiuFen,eta1.LunanPharmaceuticalGroupCo.Ltd,StateKeyaboratory.GeneticManufactureTechnologyofChineseTraditionalMedicine,Linyi276006,ShandongProvince,China【Abstract】0bjectiveToinvestigatethechangesofintestinalbarrierfuncti6、onandprotectiveeffectsofHuazhirougangranuleinratswithalcoholicfattyliverdisease.MethodsSixtySprague—Dawley(SD)ratswererandomlydividedintocontrol,model,low(1.1g。kg·d一),middle(2.2g。kg‘d一)andhighdose(4.4g‘kg一’。d一)ofHuazhirougangranuletreatmentgroups:Ratsinmodelandtreatmentgroupwerefed7、with56%alcoholonceadayforfiveweekstoestablishalcoholicfattylivermodel,andthechangesinbacterialtranslocation(BT),in—testinalmucosalpermeability(representedbylactulose(L)/mannitol(M),e.g.L/M%),bloodbiochemistry,in—testinalmucosaandliverpathohistoloyweredetermined.ResultsAttheendoffif8、thweek,thechangesofliverst
