Chronic exposure to ultraviolet radiation (UVR) induces skin tumors in hairless mice. Daily oral administration of a Polypodium leucotomos (PL) extract significantly delayed tumor development in PL‐treated versus non‐PL‐treated mice. UVR and/or PL treatment modified several oxidative stress markers. In all irradiated mice, erythrocytic glutathione S‐transferase (GST) activity and glutathione disulphide...
A single dose of ultraviolet radiation (UVR) induces significant changes in blood and skin of hairless mice. Oral administration of a hydrophilic extract of the fern Polypodium leucotomos (PL, 300 mg/kg during 5 days before UVR and for two additional days after irradiation) modulates some of the effects of UVR. Most significantly, PL administration reduced the number of proliferating cells by 13%,...
