title: Urinary excretion of alpha-fetoprotein in rats on a cirrhogenic carbon tetrachloride regimen.
abstract: Alpha-fetoprotein was detected in the serum and urine of 2- to 9-mth-old rats subjected to protracted CCl4 poisoning. During the first 3 mth of the experiment, urinary excretion of AFP was found in 30-40 per cent. of the animals, increasing to 70 per cent. thereafter. The liver lesions progressed from acute parenchymal necrosis to cirrhosis, but hepatocellular carcinomas did not develop. Uptake of tritiated thymidine by the hepatocytes increased significantly but was constant throughout the experimental period. The findings are compared to the observations made during 3mDAB-induced hepatocarcinogenesis in the rat.
