Fig. 3.
Infusion of ethanol or propanol decreased hepatic SAM concentration. Isolated rat liver was infused with ethanol (EtOH, 20 mM) or propanol (Prop, 20 mM) for 60 min, and S-adenosylmethionine (SAM) content was measured in liver lobules. Ethanol or propanol infusion resulted in a significant decrease of the liver SAM. The effect of ethanol was markedly attenuated by co-infusion of 4-methylpyrazole (4-MP, 4 mM), an inhibitor of alcohol dehydrogenase, and pyruvate (Pyr, 10 mM). Groups that do not share a common letter are significantly different (p<0.05).
