Abstract:

Abstract: In this study, Drosophila melanogaster was used as the experimental animal to study the effects of sodium nitrite on life span, reproductive capacity and antagonistic effects of Vc on sodium nitrite. The results showed that the lifespan, average longest and average shortest life span was shortened in sodium nitrite. Compared with the control group, the average life span of D.melanogaster was shortened in sodium nitrite significantly(P〈0.05 or P〈0.01) except for 30mg/ml sodium nitrite experimental group. The reproductive capacity of D.melanogaster was shortened in sodium nitrite significantly (P〈0.01). When the concentration of Vc were 0.13%, 0.40% and 1.20% in the 480mg/ml sodium nitrite Medium, with the concentration of Vc increased, the average life span of D.melanogaster was prolonged significantly(P〈0.05 or P〈0.01) except for 30mg/ml sodium nitrite experimental group of male D.melanogaster. The reproductive capacity of D.melanogaster was prolonged significantly (P〈0.01 except for 30mg/ml sodium nitrite experimental group).
