Administration of ascorbic acid (0.3, 0.75 or 1.5%) in drinking water started after the treatment of female CBA mice with 1,2-dimethylhydrazine and estradiol-dipropionate inhibited the growth of uterine sarcomas. The inhibitory effect depended upon dosage to some extent. When administered together with estradiol-dipropionate to intact mice, ascorbic acid arrested uterine growth associated with estrogen treatment.
