8-Hydroxydeoxyguanosine in human leukocyte DNA and daily health practice factors: effects of individual alcohol sensitivity.
A typical oxidative DNA damage, 8-hydroxydeoxyguanosine (8-OHdG), was evaluated in human polymorphonuclear leukocytes (PMN) and mononuclear leukocytes (MN) by an anaerobic determination method. The mean 8-OHdG values were the lowest level ever reported [PMN, 3.07 +/- 1.45; MN, 2.37 +/- 1.21 8-OHdG/10(6) deoxyguanosine molecules (dG); n = 92]. According to a self-administered questionnaire to 92 healthy male workers, the relationship was investigated between 8-OHdG in leukocytes and daily health practice factors, that is, the frequency of physical exercise, smoking status, alcohol drinking, nutritional balance, and the degree of mental stress. A significant difference was observed only in alcohol drinking in subjects classified by aldehyde-dehydrogenase 2 isozyme (ALDH2) genotype. Habitual alcohol intake appeared to increase 8-OHdG in PMN from ALDH2-deficient subjects. Neither age, body mass index, nor any other factors examined showed any significant correlation with the 8-OHdG levels in leukocytes.
