摘　　要：以果蝇为实验动物,探讨了不同浓度的Zn^(2+)对铅中毒果蝇生育力和寿命的影响,并以SOD活性、CAT活性、MDA含量为指标评价其抗氧化能力。结果表明,1.0×10^(-3) g·mL^(-1) Zn^(2+)对铅中毒果蝇的生育力有较好的促进作用,能消减对雄性果蝇生殖细胞的毒害作用;对铅中毒果蝇的寿命也有明显的延长作用;同时减缓了铅中毒果蝇体内SOD和CAT活性的降低,降低了MDA含量,提高了铅中毒果蝇的抗氧化能力。Using Drosophila melanogaster as experimental animals,we investigated the effects of different concentrations of Zn^2+on the reproductive capacity and lifetime of lead-poisoned Drosophila melanogaster,and evaluated the antioxidant ability by SOD activity,CAT activity,and MDA content.The results show that 1.0×10^-3 g·mL^-1 Zn^2+can facilitate the reproductive capacity of lead-poisoned Drosophila melanogaster,can reduce the toxic effect on the germ cells of male Drosophila melanogaster,and has a significant prolongation effect on the lifetime of lead-poisoned Drosophila melanogaster.Moreover,1.0×10^-3 g·mL^-1 Zn^2+can slow down the decrease of SOD and CAT activities and reduce the MDA content in Drosophila melanogaster,which improve the antioxidant ability of lead-poisoned Drosophila melanogaster.
