The function of: (see article), fits the tumors weight growth for all studied generations in both control and treated animals. Morphological studies show the transplantable tumors in A mice to lose their similarity to a spontaneous tumor--low differentiated adenocarcinoma. Meanwhile, the tumors in C3H mice have a high differentiation level which is typical for the original tumor. 1-nitroso-1-methylurea is very effective against the first generation of tumors in both strains of mice. The tumors response to the drug becomes weaker with further passages. 1-nitroso-1-methyl urea is superior to other nitrous derivatives when used in such tumor models as breast adenocarcinoma in C3H mice.
