2、、流式细胞术和透射电镜的方法观察钼对绵羊肝脏细胞损伤的影响。与I组相比:Ⅱ、Ⅲ组肝脏超氧化物歧化酶(SOD)和黄嘌呤氧化酶(XOD)活性显著下降(P<0.01),丙二醛(MDA)和N0含量显著升高(P<0.01),血清N()含量和相应抗氧化酶活性变化与肝脏中的一致;II、1I组肝脏细胞Go/G期和凋亡细胞百分数显著升高(P3、,严重空泡化。结论:日粮钼含量30mg/kg及其以上可引起绵羊肝脏抗氧化功能降低和N()含量升高,导致细胞增殖分化受阻,细胞受损程度与机体钼暴露剂量和时间有关。关键词:钼;肝脏;绵羊;N0;细胞损伤中图分类号:$859.8文献标志码:A文章编号:10054545(2013)09—1436—06EffectofvariousdosesofmolybdenumOilthecellulardamageofliverinsheepSONGChao,YANGZi-jun“,CAOXiao—dan,ZHANGPeng,WANGYa—lei,GUOShuzhou4、(1.LivestockScience&TechnologyCollege,HenanUniversityofScienceandTechnology,Luoy~ang471000,China;2.ShanghaiVeterinaryResearchInstitute,ChineseAcademyofAgriculturalScience,Shanghai200241,China)Abstract:】heexperimentaimedtoexploretheeffectofmolybdenumonNOmetabolismandhepa—tocell5、ularinjuryinsheepbythemethodsofchemicalcolorimetry,flowcytometryandultrastrueturalpathology.Threedifferentdosesofmolybdenum(Mo0mg/kg,group工;Mo30mg/kg,mo—lybdenumgroupII;Mo60mg/kg,molybdenumgroup1I)wereaddedtothebasaldiets(Mo5.61mg/kg)tofeed18sixty—days—oldsmalltailedHansheep(26、0±1.34)kgdividedintothreegroupsrandomlyfor120days.Autopsiesweremadeperiodicallytogetthebloodandtissuespecimens.Theresultshowedthatinthelivertissue,thema1ondialdehvde(MDA)contentsandthe1evelsofN()wereincreased(P<0.01)ingroup1IandⅢ,thesuperoxidedismutase(SOD)andxanthineoxide(XOD7、)activitiesingroup1andⅢwerelower(P8、IandIlIthaningroupI(Pd0.01)byFCM.ChangesaboveingroupIIretarde
