1、1436中國獸醫(yī)學報2013年9月第33卷第9期ChinJVetSciSep.2013Vo1.33No.9不同劑量鉬對綿羊肝臟細胞的損傷作用宋超,楊自軍,曹曉丹。,張鵬,王亞壘,郭書周(1.河南科技大學動物科技學院,河南洛陽471000;2.中國農業(yè)科學院上海獸醫(yī)研究所,上海200241)摘要:選用18只2月齡小尾寒羊,體質量約為(20±1.34)kg,隨機分為3組,分別在基礎日糧(Mo5.61mg/kg)中添加不同劑量的鉬(mg/kg)構成加鉬日糧(I組Mo0、lI組Mo30、IlI組Mo60),試驗周期120d,定期采血,剖殺取樣,以化學比色法
2、、流式細胞術和透射電鏡的方法觀察鉬對綿羊肝臟細胞損傷的影響。與I組相比:Ⅱ、Ⅲ組肝臟超氧化物歧化酶(SOD)和黃嘌呤氧化酶(XOD)活性顯著下降(P<0.01),丙二醛(MDA)和N0含量顯著升高(P<0.01),血清N()含量和相應抗氧化酶活性變化與肝臟中的一致;II、1I組肝臟細胞Go/G期和凋亡細胞百分數(shù)顯著升高(P3、,嚴重空泡化。結論:日糧鉬含量30mg/kg及其以上可引起綿羊肝臟抗氧化功能降低和N()含量升高,導致細胞增殖分化受阻,細胞受損程度與機體鉬暴露劑量和時間有關。關鍵詞:鉬;肝臟;綿羊;N0;細胞損傷中圖分類號:$859.8文獻標志碼:A文章編號: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
