Abstract
A study was undertaken in rats to evaluate the effects of short-term oral ethanol administration on the levels of fatty acid ethyl esters (FAEE) in brain and peripheral organs in the presence and absence of pretreatment with L-carnitine. Administration of ethanol to rats for seven days resulted in fatty acid ethyl ester formation, particularly in the heart and brain, but also in the kidney and liver. FAEE generation was associated with a significant increase of GSH transferase activity. Treatment with L-carnitine significantly reduced both FAEE and GSH transferase activity, and these effects were associated with a significant decrease in alcohol blood concentrations. The present evidence supports the hypothesis that fatty acid ethyl esters could be mediators involved in the production of alcohol-dependent syndromes. Administration of L-carnitine through an increment in lipid metabolism and turnover, and by the modulation of cellular antioxidant enzymes, greatly reduces these metabolic abnormalities supporting its potential usefulness as a pharmacological tool in alcoholism management.
