Metabolic effects of ethanol in the rat liver.
The NADPH is one of the cofactors in ethanol metabolism. The aim of the study was to investigate the effect of ethanol on a NADPH generating enzyme (G6P-DH) and on some metabolic parameters of the liver. After a 2-day starvation period rats were fed a lipid free diet for three days. During this refeeding period the animals were divided into three groups; they received a single daily dose of 4 g per kg b.w. ethanol, isocaloric aqueous glucose solution or water by gastric tube. In response to ethanol the activity of hepatic G6P-DH decreased. The amount of triglyceride remained unchanged, certain changes occurred in the fatty acid composition of total lipid. The liver glycogen content was elevated. In female rats treated with ethanol the activity of glucose-6-phosphatase increased.
