To understand the effects of DEN on the endocrine system and the mechanisms for the sex differences in the animal hepatocarcinogenesis initiated by DEN, we designed the present experiment to study the effects of DEN on the pituitary ultrastructure, serum levels of several hormones, as well as expression and activities of several sex-differentiated liver enzymes.
