Effect of X rays alone or combined with diethylnitrosamine on tumor induction in infant mouse liver.
No full textThe possible combined effects of the initiator diethylnitrosamine (DEN) with X rays on cancer induction in C57BL/Cnb mouse liver were evaluated. Four groups of infant mice were treated as follows: with DEN alone, with X rays alone, with DEN + X rays, and with X rays + DEN. Mice in each group were killed at 10-week intervals over 70 weeks. The following parameters were measured: body weight, liver weight, number and size of macroscopic liver lesions, and number and total surface of the different types of microscopic liver lesions. The number of induced liver foci and carcinomas was found to depend essentially on the dose of DEN. X irradiation did not produce any combined effect on the induction of foci and carcinomas when given 7 days before or after DEN administration
