[Action of a herbicide (paraquat) on hepatocytes in histiotypic culture].

Abstract

The toxicant action on hepatocytes of "paraquat" introduced at very low concentrations in an in vitro culture of such cells is here established. Mitoses are slowed down and moreover, the lysosomial system is impaired, thus inducing a decrease in its enzymic reactions and the proliferation of very large vesicles.
