Text: We found significant differences in p53 and polyamines in forearms from the sun-damaged group (11. 5 + / - 1. 2 % for p53, 65. 5 + / - 1. 9 nmol/g for putrescine, and 187. 7 + / - 3. 3 nmol/g for spermidine) compared with the group with sun damage plus AK (20. 9 + / - 2. 3 % for p53, P = 0. 0001 ; 81. 7 + / - 3. 9 nmol/g for putrescine, P = 0. 0001 ; 209. 4 + / - 8. 2 nmol/g for spermidine, P < 0. 06).
