title: Morphology of early changes in liver carcinogenesis induced by methapyrilene.
abstract: Two weeks of treatment with the liver carcinogen methapyrilene induced a significant increase in mitochondria of periportal hepatocytes in F344 rats. Administration of [3H]-methapyrilene hydrochloride resulted in a pronounced concentration of bound radioactivity in the periportal hepatocytes, with mitochondria being the principal site of intracellular binding. The nuclei of the liver cells were unlabeled.
