title: Cytogenetic effects of diethylstilbestrol-diphosphate (DES-dp) on mouse bone marrow monitored by the micronucleus test.
abstract: 6 dosages of diethylstilbestrol-diphosphate (DES-dp), ranging from 0.01 to 500 mg per kg of body weight were compared to saline and phosphate buffered saline (negative controls) and two dosages of cyclophosphamide (positive control) in the micronucleus test with 115 ICR mice. DES-dp failed to generate a significant increase in micronucleated polychromatic erythrocytes over negative controls. Cyclophosphamide produced a dose-related increase in micronuclei similar to previously published reports. Iit was therefore determined that the micronucleus test did not detect the types of chromosomal changes known to be generated by DES-dp and DES.
