To evaluate effects of centipede on life span of drosophila and on the appearance of the filial generation.
Drosophila melanogaster (male and female) were cultured in tubes with centipede extraction at concentrations of 0, 0.2%, 1%, 2.5%, or 5% until all drosophila died. The appearance of the filial generation were observed.
The life span, including average, longest and shortest life span was shortened in exposed groups of both sexes and significantly dose-dependent. The appearance of the filial generation showed normal.
Centipede extracts accelerates the aging of drosophila and shortens their life span. The appearance of the filial generation is not affected. Clinic using centipede for a long period should be carefully.
