Azathioprine at 40 mg/kg was administered orally to females either on gestation day (GD) 7, 8, 9, 10, 11, 12, 13 or 14 and cesarean section was conducted on GD 21. The uterine implants were classified as live fetus, or resorbed or dead fetus. The live fetuses were weighed and examined for external or skeletal anomalies. There were significant increases in % of postimplantation losses and the corresponding decreases in number of live fetuses in the GD 7, 8, 9 and 10 treatment groups, and the critical period of fetal deaths were determined from GD 7 to 10. In the surviving fetuses, there were decreases in fetal body weights in the GD 9, 11 and 12 treatment groups. No treatment-related external orskeletal malformations were bserved in any treatment groups. In conclusion, these were embryolethality with stage specificity fromGD 7 to 10 but were no teratogenic potentials in this experimental conditions.}, pages = {1--4}, title = {Developmental toxicity study of immunosuppressive compound, azathioprine in rats Effects of a single treatment during the organogenesis}, year = {2023}, yomi = {バン, ヨシキ} }
