核酸胶囊对延缓衰老作用的实验研究

目的　研究核酸胶囊的延缓衰老作用。方法　老龄大鼠抗氧化试验、果蝇生存试验。结果　各剂量组大鼠血清MDA含量明显低于对照组 (P <0 .0 1) ,低剂量组、中剂量组血清SOD活力明显高于对照组 (P <0 .0 1,P <0 .0 5 ) ,各剂量组大鼠血清GSH -Px活力明显高于对照组 (P <0 .0 1) ;雄蝇的 0 .2 1%浓度组平均寿命和平均最高寿命高于对照组 (P <0 .0 5或P <0 .0 1)、0 .0 7%浓度组的平均最高寿命高于对照组 (P <0 .0 5 )。结论　核酸胶囊具有延缓衰老作用

A Study on the Role of Nucleic Acid Capsule in Testing Delay-aging Function in Rats and Drosophila

Objective To study the role of nucleic acid capsule in delay-aging function in rats and drosophila.Methods Anti-oxidation test in rat and longevity test in drosophila were carried out.Results The concentrations of serum MDA in all administrated dose groups were lower than that of the control (P<0.01). The concentrations of serum SOD in low and moderate dose groups were higher than those of control(P<0.01,P<0.05).The concentrations of serum GSH?Px in all administrated dose groups were higher than those of the control (P<0.01).The average life-span and the average longest life-span of male drosophila in 0.21% group were prolonged as compared with the control (P<0.05,P<0.01).The average longest life-span of male drosophila in 0.07% group was prolonged as compared with the control (P< 0.05).Conclusion Nucleic acid capsule has delay-aging function effect for rats and drosophila.
