Ddy mice which were treated with 0.32 mg of dexamethasone were used. Vitamin B12 was injected subcutaneously into the animals from the 10th day to the 13th day with a dosage of 0.1r, 1r, or 10r. The rate of incidence of cleft palate was decreased to 77.0% in the 0.1r group, 58.1% in the 1r group and 67.9% in the 10r group as compared to the control value of 88.5%.
