Recent studies suggest that moderate alcohol consumption is associated with a low risk of cancer, coronary heart disease, and other diseases. Most of these diseases are considered to be related to the action of reactive oxygen species (ROS) at certain stages of disease progression. However, considerable evidence exists indicating that ethanol generates ROS in vivo. ⋯ ROS may then cause cell damage in liver, as suggested by the positive correlation between the total biopyrrins levels and the serum GOT, GPT, and gammaGTP levels. However, since ROS may be more effectively counteracted by uric acid in organs other than the liver, DNA damage may be suppressed rather than induced. Accordingly, moderate alcohol consumption seems to have the overall effect of reducing DNA damage, as shown by the decrease in urinary 8-OHdG levels observed in our study.
