The carcinogenic effect of dimethylnitrosamine on the chinese hamster (Cricetulus griseus)

Cancer Letters, 1975
Three groups of Chinese hamsters (20 males, 20 females/group) received weekly subcutaneous injections for life of dimethylnitrosamine (DMN) at dose levels 0.20, 0.10 and 0.05 of the LD50.
