Methods With C. elegans as living model, the life span and the average number of offsprings were determined under normal culture conditions; The survival rate under oxidative stress and the expression of heat shock protein-16.2 (HSP-16.2) and superoxide dismutase-3 (SOD-3) were determined. Results Under the normal culture conditions, the life span of C. elegans was significantly extended by AMP-1 and AMP-2 without the damage of the reproductive capacity; The expression of HS
