Abstract:
Objective To investigate the effects of MCSO on physiological behavior and antioxidant index in D.melanogaster.Methods One-day-old wild type D.melanogaster was divided into control group,0.25％,0.5％,1％,2％and 4％dose groups,as well as male and female groups.The control group was exposed to the base medium,and each dose group was exposed to the MCSO medium added with 0.25％,0.5％,1％,2％and 4％concentrations,respectively.The optimal dosage concentration and time of administration were investigated by climbing experiment.Then the flies were divided into control group,model group and MCSO group.The model group was established by depriving the flies of sleep through repeated nocturnal light stimulation.Period of drug treatment,appetite test,negative geotaxis ability test,stress test,olfactory memory test,and sleep-wake rhythm detection were used to explore the effects of MCSO on their physiological behavior.The activities of super oxidase dismutase(SOD),catalase(CAT),and malondialdehyde(MDA)were detected by enzyme-linked immunosorbent assay.Results MCSO enhanced the locomotory ability of 30-day-old D.melanogaster(P＜0.01),increased the activity of SOD and CAT(P＜0.01),and decreased the concentration of MDA(P＜0.01).Improve olfactory memory of senile fruit flies.After sleep deprivation,the night sleep time of female Drosophila model group was reduced(P＜0.05),and that of male Drosophila model group was reduced(P＜0.01).After feeding MCSO,the night sleep time of female drosophila model group was extended(P＜0.05),and that of male drosophila model group was extended(P＜0.01).Conclusions MCSO had a certain antioxidant effect,prolonging the sleep time and improving the olfactory memory of sleep-deprived Drosophila.
