Antioxidant mediators following skin UVB-radiation. Dorsal skin was exposed to a single dose of UVB (2.4 J cm⁻¹) and changes were analyzed at different intervals. Activity profiles of: (A) superoxide dismutase (SOD) and catalase activity (CAT); (B) glutathione content (GSH) level; (C) myeloperoxidase activity (MPO). For details see Materials and Methods. Data are expressed as mean ± SEM of 6–8 animals per group (* p < 0.05, ** p < 0.01 and *** p < 0.001 difference versus Basal, ANOVA, Newman–Keuls post-test).
