Abstract
Hairless mice were irradiated with fluorescent sun lamp tubes (peak emission at 313 nm). A singificant increase in epidermal ornithine decarboxylase activity was found after 2 hr. A maximum 80-fold increase was found after 24 hr, decreasing again at 48 hr. Epidermal DNA synthesis was decreased at 6 hr and 24 hr increasing to a maximum 48 hr after irradiation. These results show that polyamine biosynthetic enzyme activity precedes the delayed increase in epidermal DNA synthesis following ultraviolet light exposure.Entities:
