中文摘要:
      为了研究Zn2+对果蝇生育力和寿命及抗氧化能力的影响。以黑腹果蝇(Drosophila melanogaster)为研究动物,用生存实验来考查不同浓度的Zn2+处理果蝇,研究果蝇F1-F4代生育力和寿命的变化,雌、雄果蝇数量的变化,抗氧化酶SOD、CAT的活力及MDA含量的变化。结果显示:添加Zn2+浓度为1.0 g/mL可以使F1-F4代雌、雄果蝇世代生育力增强,寿命延长,而在Zn2+浓度为2.0×10-3g/mL时果蝇体内MDA含量大量积累,SOD和CAT活性急剧降低,使果蝇提前衰老、死亡并且降低或丧失生殖能力,而Zn2+对果蝇性别分化影响不大,总体接近于1:1。因此,适当浓度的Zn2+可以延长果蝇寿命,增强其生殖力,提高抗氧化能力。
英文摘要:
      The effects of Zn2+ on the reproductive capacity, life and antioxidation of Drosophila melanogaster were studied in this paper.D. melanogaster was treated with Zn2+ of different concentrations in survival experiments, and the changes in reproductive capacity and life of its F1 to F4, the changes in the number of female and male, the activities of antioxidant enzymes SOD, CAT and MDA content were studied. The results showed that adding 1.0 g/mL Zn2+ could enhance the reproductive capacity and prolong the life of F1-F4 female and male. When the concentration of Zn2+ was 2×10-3 g/mL, the content of MDA in the fruit flies was accumulated, and the activity of SOD and CAT decreased rapidly. The fruit flies was senescent, dead and reduced or lost. Zn2+ had little effect on the sex differentiation of fruit flies, which was almost 1:1. It could be concluded that Zn2+ at appropriate concentrations can prolong the life of fruit flies, enhance its fecundity, and improve its antioxidation.
