砷致小鼠脂质过氧化及锌、硒对砷的干预实验研究
Journal Title: Science Paper Online - Year 2007, Vol 2, Issue 11
Abstract
【目的】探讨砷对小鼠血清及肝脏脂质过氧化的影响及锌、硒对它的干预作用。【方法】采用亚慢性毒性实验方法,实验结束后分别测定小鼠血清、肝脏组织中脂质过氧化产物丙二醛(MDA) 和谷胱甘肽S-转移酶(GST)含量及超氧化物歧化酶(SOD)、谷胱甘肽过氧化物酶(GSH-Px)的活力，同时观察锌、硒干预后对染砷小鼠体内抗氧化水平的影响。【结果】随着砷染毒剂量的增加，小鼠血清及肝脏组织中MDA和GST含量显著增加,SOD、GSH-Px活性显著降低,且呈剂量-效应关系。锌、硒能抑制MDA和GST生成量,提高SOD、GSH-Px活性。【结论】砷可致机体脂质过氧化, 锌、硒可拮抗砷的脂质过氧化作用。
