摘要
大鼠低温暴露后血及肝脏组织中ＬＰＯ含量显著升高，ＧＳＨ一Ｐｘ和ＳＯＤ活性明显下降；透射电镜下观察，肝线粒体明显肿胀，嵴断裂，结构不清甚至消失，基质电子密度降低。饲料中加入一定量的ＶＥ或沙棘油均可使上述指标的变化明显改善，接近于室温下正常对照组水平。沙棘油的改善效果优于同等剂量的ＶＥ。表明：沙棘油和ＶＢ可通过其抗脂质过氧化作用，提高机体的耐寒力。
he changes of lipid peroxides content(LPO),glutathione
peroxidase(GSH-Px)and superoxide dismutase(SOD)activities in blood and liver of rats were
determined after cold exposure with Sea Buckthron oil or vitamin E supplement into the feed, in
order to observe their effects.LPO content markedly increased,but the activities of GSH-Px and
SOD were significa- ntly decredtsed.TEM was empolyed to study the morphological changes of
mitochondria。Sea Buckthron oil or vitamin E could make the above values close to levels of
the control group。The effect of Sea Buckthron oil was better than that of vitamin E when doses
were the same。Sea Buckthron oil and Vitamin E might enhance cold tolerance through anti一
lipid peroxi一 dation。
