The general toxic and hepatocarcinogenic effects of diethylnitrosamine after stimulation of its metabolism with 1,4-bis[2-(3,5-dichloropyridyloxy)]-benzene (TCPOBOP) were studied. The hydroxylating activity of liver microsomes of C57Bl/6Mv mice towards p-nitrophenol increased more than 4-fold 3 days after injection of TCPOBOP. Injection of diethylnitrosamine 3 days after TCPOBOP caused a lesser body weight loss and decrease of food consumption in C57Bl/6Mv mice than in response to diethylnitrosamine without preinduction. Injection of diethylnitrosamine to suckling ICR mice after TCPOBOP induction of cytochrome P450 2e1 activity led to development of 2-fold lesser number of tumors and pretumorous nodes in the liver in comparison with animals injected with diethylnitrosamine without induction. These data indicated that metabolism stimulation reduced the general toxic and hepatocarcinogenic effects of diethylnitrosamine.
