The effect of ethanol on polyamine acetylation was studied in rat liver. Animals were fed on nutritionally complete liquid diets with 36% or 12% of total calories supplied as ethanol or isocaloric carbohydrates for 4 months. The diet with 36% calories as ethanol significantly increased the activity of cytosolic spermidine/spermine N1-acetyltransferase, the rate-limiting enzyme in polyamine interconversion. Such a stimulation did not appear in rats under the 12% ethanol regimen. The stimulation of spermidine/spermine N1-acetyltransferase was associated with increases in putrescine and spermidine concentrations, an appearance of N1-acetylspermidine, and a decrease in spermine. These results suggest that chronic ethanol intake stimulates the acetylation of polyamines and their interconversion in rat liver.

D000437	Alcoholism	A primary, chronic disease with genetic, psychosocial, and environmental factors influencing its development and manifestations. The disease is often progressive and fatal. It is characterized by impaired control over drinking, preoccupation with the drug alcohol, use of alcohol despite adverse consequences, and distortions in thinking, most notably denial. Each of these symptoms may be continuous or periodic.
