On the 21st day of gestation all the animals were sacrificed under ether anesthesia and fetuses were collected for routine teratological evaluations. There was no significant change in maternal body weight or food consumption and no external, visceral, skeletal and histological abnormalities in the vehicle control and bone wax dosed groups. Abnormalities were observed in the positive control group.Toxicology
