The effects of ethanol, 4-methylpyrazole (4-MP), and acetaldehyde on albumin and urea synthesis, and on polysome aggregation were studied in isolated perfused rabbit livers. Fed or fasted males served as donors and the perfusate contained ethanol, 200 mg per 100 ml, with and without 1.5 mM 4-MP; or acetaldehyde, 2 mg per 100 ml, with and without 1.5 mM 4-MP. The results indicate that in livers from fed donors ethanol depressed albumin and urea synthesis and bound polysomes were disaggregated. Perfusion with acetaldehyde caused a similar decrease in albumin and urea synthesis, but did not cause polysome disaggregation. The addition of 4-MP to the ethanol perfusates did not enhance albumin or urea synthesis but did prevent polysome disaggregation. When the donor was fasted, the addition of 4-MP to the ethanol perfusates restored urea synthesis and polysome aggregation to fasted control levels. In the livers from fasted donors, acetaldehyde did not lower albumin or urea synthesis and had no effect on polysome aggregation. The results indicate that the hepatic responses to ethanol and acetaldehyde are different if the livers are derived from fed or fasted donors, and it is not possible to ascribe the toxic effects of acetaldehyde or ethanol on albumin and urea synthesis to either agent, per se.
