Abstract
Hepatic vein thrombosis, as well as hepatocellular carcinomas, was induced in inbred C3H male and female mice ingesting 10 ppm of dieldrin, aldrin, heptachlor, or heptachlor epoxide in the diet. Thrombosis was present in 5% of mice ingesting dieldrin or aldrin and in 10.5% of mice ingesting heptachlor or heptachlor epoxide. Occlusion of the hepatic vein often resulted in infarcts of the liver. Females ingesting heptachlor or heptachlor epoxide were slightly more susceptible than males. There was no difference between male and female mice ingesting dieldrin or aldrin. Hepatic vein thrombosis did not appear to be related to the development of carcinoma of the liver because it was present in livers without carcinomas as well. Thrombosis was usually seen only in the liver but also rarely was present in the atria of the heart.
