title: Effects of carbon tetrachloride on albumin synthesis.
abstract: The effects of CCl(4) on albumin synthesis were studied employing the isolated perfused liver. Carbonate-(14)C was used to measure newly synthesized albumin. 2.5 ml of CCl(4) was administered by stomach tube 2 hr before perfusion. Albumin synthesis decreased from 36 to 5 mg following the ingestion of CCl(4). Preperfusing the livers for 1 hr before measuring albumin synthesis resulted in an increase to 12 mg, and the addition of tryptophan to a final concentration of 10 mM resulted in a further increase to 19 mg. Cortisone did not protect against the toxic effects of CCl(4) when administered to the donor rabbits. Fasting resulted in an increased sensitivity to CCl(4) and an antioxidant was not effective in protecting against the toxic manifestations of CCl(4).
