Popis: C3HA female mice received 0.1-0.3 mg/g body weight diethylstilbestrol (DES) on day 17 of gestation. Their descendants received a total of 20 injections of 1.2-dimethylhydrazine (DMH), subcutaneously, weekly, starting from month 2. Prenatal DES significantly inhibited the development of DMH-induced clitoral gland tumors, particularly, hemorrhagic ovarian cysts which were the frequent cause of death due to their rupture into the abdominal cavity. A significant decrease in cyst incidence resulted in higher survival in mice receiving combined therapy. The results were attributed to DES-induced hyperestrogenization which was confirmed by vaginal smears examination.
