By i.p. application of 70 or 100 mg/kg ethyl-nitrosourea, resp., to gravide Göttingen miniature pigs on days 14 or 16, resp., of gestation massive malformations of the skeletal system were produced. The experiments demonstrated the teratogenic effect of ethylnitrosourea on non-rodents, ascertained the period of determination of the skeletal system in pigs, confirmed the concentration effect in teratogenesis as well as the ineffectiveness of biological barriers with adequately high dosages.
