title: Inhibition of hepatic uptake of alpha aminoisobutyric acid by ethanol: effects of pyrazole and metabolites of ethanol.
abstract: Ethanol inhibits the uptake of AIB by the isolated perfused rat liver. However, if the metabolism of ethanol is blocked by pyrazole, there is no reduction in accumulation of AIB by the liver. Acetaldehyde and acetate, metabolites of ethanol have no effect on AIB uptake by the liver. The inhibition of urea synthesis by ethanol is also prevented by pyrazole. Neither of the metabolites of ethanol inhibit urea synthesis in the isolated liver.
