| 摘 要： | 目的 观察不同浓度的硫酸铈培养基培养果蝇三龄幼虫超氧化物歧化酶(SOD)及过氧化氢酶(CAT)活力的变化.方法 以不同浓度(1、4、16、64、256、1 024 mg/L)硫酸铈的培养基培养野生型黑腹果蝇,测定果蝇三龄幼虫SOD及CAT活力,并与基本培养基的对照组进行比较.结果 与对照组比较,64～1 024 mg/L硫酸铈组果蝇SOD及CAT活力降低,差异有统计学意义(P＜0.05,P＜0.01),1～16 mg/L硫酸铈组果蝇三龄幼虫SOD和CAT活力上升,差异有统计学意义(P＜0.05,P＜0.01).结论 Ce(SO4)2对果蝇具有一定的毒性效应.

| Abstract: | Objective To understand the effect of cerium on the activity of SOD and CAT in Drosophila melanogaster.Methods Drosophila melanogasters were treated with cerium by adding cerium sulfate [Ce(SO4)2] into the culture medium at different concentrations(0,1,4,16,64,256 and 1 024 mg/L).The activity of SOD and CAT of the third-instar larvae were analyzed.Result Compared with the control,at 64-1 024 mg/L,the activity of SOD and CAT in the third-instar larvae significantly decreased and at 1-16 mg/L,the activity of SOD and CAT significantly increased Conclusion It suggested that cerium sulfate [Ce(SO4)2] has an oxidant toxicity to Drosophila melanogaster. |
