In this paper, the biological effects of diethylnitrosamine have been studied under controlled conditions of its metabolism in mice of different ages. The data presented indicate that diethylnitrosamine in a non-metabolized form exerts general toxic and hepatocarcinogenic effects while alkylating agents of this compound produce toxic liver injury. To our knowledge, the data presented impel to revise the general notion of an exceptional role of mutagenic activation in the carcinogenic effect of chemicals.
