Effects of topical formulations containing silymarin in pre- and post-treatment on different antioxidant enzyme activities in dorsal skin tissue homogenate induced by UVB irradiation. GPX (a); SOD (b); CAT (c) and MDA (d) activities are expressed as % of enzyme activity of untreated guinea pigs. Bars represent means ± S.D., n = 5. In case of GPX, SOD, CAT, MDA evaluations Repeated-Measures ANOVA and Pearson correlation tests were performed. Significant differences are marked with * and + in the figures, showing the significance levels in the case of compositions containing SM in suspended or dissolved forms.
