2、实验持续28d后进行l取样。记录大鼠的生长性能和肝脏重量,并计算肝脏指数;检测血清中谷丙转氨酶(ALT)、谷草转氨酶(AST)、碱性.瞵酸酶(ALP)活性和总胆红素(TBIL)、总蛋白(TP)含量;H&E染色观察肝组织病理变化;检测肝脏组织中超氧化物歧化酶(SOD)活性和丙二醛(MDA)含量。结果表明,绿原酸能够显著降低陵性肝脏损伤大鼠的末重、平均日增重和食物转化率(P<0.05);显著降低大鼠肝脏重量和肝脏指数(P3、),降幅分别为12%、13%、17%和50%;显著升高血清中TP含量和肝脏组织中SOD活性(P<0.01或P<0.057增幅分别为17%和23%;显著降低肝脏组织中MDA含量(P<0.05),降幅为33%;绿原酸能够改善慢性肝脏损伤大鼠的肝组织结构。因此,绿原酸对长期脂多糖应激引起的大鼠慢性肝脏损伤有一定的保护作用。关键词:绿原酸;保护作用;肝脏损伤;脂多糖文章篇号:1673.9078(2014)7.23.26ProtectiveEfectsofChlorogenicAcid0nLip0p0lysacchari4、de_inducedChronicLilverIlnliuUryi。nRatsYANG,u.hui1ZHoUY.anlRUANZhenglMIShu.mei1ZHoULi-li1、ⅦNYan.mei1LI)【jaO.1an1,,,,,,,JLNGMin.YINYu.1ong(1.StateKeyLaboratoryofFoodScienceandTechnology,CollegeofLifeScienceandFoodEngineering,NanchangUniversity,Nanchang330047,5、China)(2.InstituteofSubtropicalAgriculture,ChineseAcademyofSciences,Changsha410125,China)Abstract:Ratswererandomlydividedintothemodelgroupandchlorogenicaid(CGA)一supplementedgroup,andatthe28thdaytheratsweresacrificed.Thegrowthperformance,liverweightandliverin6、dexofeachratwereanalyzed.Theactivitiesofalanineaminotransferase(ALT),aspartateaminotransferase(AST)andalkalinephosphatase(6LLP)andthecontentsoftotalbilirubin(TBIL)andtotalprotein(TP)inserumwereassayed.HepaticpathologicalchangeswereobservedbyH&Estainingmethod7、.Theactivitiesofsuperoxidedismutase(SOD)andthemalondialdehyde(MDA)contentinliverweredetermined.Comp~edwiththemodelgroup,thefinishbodyweight,averagedailygainandfoodeficiencyratio(FER),liverweightandliverindexinCGA-supplementedgroupweresignificantlydecreasedfP8、<0.05).TheactivitiesofAAST,ALPandthelevelofTBILinserumdeclinedsignificantly(P<0.05orP<0.01),andthedecliningrateswere12%,13%,17%and50%,respectively~TPcontentinsela.1mandSODactivityinliverweresign
