Abstract
The spin trapping method combined with EPR spectroscopy has been employed by a number of laboratories to study alcohol-induced oxidative stress. Ethanol is converted to a free radical metabolite, the 1-hydroxyethyl radical in chemical reactions that generate hydroxyl radicals, in incubations of rat liver microsomes and in vivo. Furthermore, both acute and chronic ethanol administration leads to formation of radicals in the liver that are presumed to be products of lipid peroxidation. In general, overall radical production is enhanced by treatments known to be involved in alcoholic liver injury, such as chronic alcohol administration along with high levels of dietary fat.
