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.
