PG - 104-10 LID - S0890-6238(15)30022-8 [pii] LID - 10.1016/j.reprotox.2015.09.004 [doi] AB - Rabbits may serve as a useful model for predicting the human risk for methanol (MeOH) teratogenicity, which currently is unknown. New Zealand white (NZW) rabbits are resistant to the MeOH-initiated gross morphological anomalies characteristically observed in several strains of mice and rats, but skeletal development has not been assessed. Pregnant rabbits were administered 2 doses of 2g/kg MeOH on gestational day (GD) 7 or 8, and assessed for skeletal abnormalities on GD 29. Variations between treated and control fetuses were observed only in the number of post-lumbar vertebrae, where MeOH-exposed fetuses had fewer ossified vertebrae, which has not been reported for rodents. Furthermore, rabbits did not exhibit the MeOH-initiated skeletal defects characteristically reported for rodent fetuses. These results expand the morphological breadth of the relative species-dependent resistance of rabbits to MeOH teratogenicity compared to rodents, yet reveal a novel skeletal defect or delay in ossification not reported for rodents.
