Abstract：
:The effect of commercial saccharin preparations on urethan-induced mouse lung tumorigenesis was assessed by gavaging groups of male strain A mice with 1-g/kg doses of each saccharin preparation on a daily basis 5 days/week. Gavage was initiated 1 week before i.p. injection of either a low (0.1 mg/g) or a high (1 mg/g) dose of urethan and continued until the mice were sacrificed 16 weeks after urethan administration. The average number of surface lung tumors per mouse for each group of mice was determined and was compared statistically with the appropriate control group. The commercial saccharin preparations did not produce an elevated lung tumor response when administered alone. One of the four saccharin preparations enhanced the lung tumor response to urethan when given in conjunction with the low dose of urethan, but this enhancement was not statistically significant. At the high urethan dose, all saccharin preparations produced a statistically significant enhancement of the lung tumor response to urethan.
