The aim of this study is to test the protective effects of lycopene on the dermal fibroblasts under UNV oxidative stress. The model used in this experiment was established by exposing the mouse dermal fibroblasts to UVA(5 J/cm2)in X min and the cell proliferative activity was detected by MTT method. The activities of superoxide dismutase(SOD), catalase(CAT), glutathione peroxidase(GSH-PX)and malondialdehyde(MDA)were also tested to illustrate the protective effect of lycopene. Results showed that the mortali...
