Influence of melon concentrate application on the melanin level after irradiation of human skin explants. (A) Fontana Masson histochemical staining of human skin explants for melanin observation. Arrows show melanin; (B) Melanin level determined after histochemistry analysis on at least 30 transverse sections per skin explant. Relative levels were presented in arbitrary units as mean ± SEM. * p < 0.05 compared with unirradiated skin explants, † p < 0.05 compared with irradiated skin explants, § < 0.05 effect of melon concentrate treatment compared with the irradiated + placebo cream group. NS: non-significant.
