[Modifying effect of ascorbic acid and sodium ascorbate on uterine carcomogenesis induced by 1,2-dimethylhydrazine in CBA mice].

Administration of ascorbic acid (0.3% in drinking water) inhibited the promoting effect of estradiol dipropionate on the 1,2-dimethylhydrazine-induced uterine sarcomogenesis in CBA mice. However administration of sodium ascorbate intensified the promoting effect of estradiol on the uterine sarcomogenesis, as evidenced by the shortening of the periods of tumour incidence.
