Influence of 4-Methyl-2-thiouracil on the Teratogenic Activity of Hypervitaminosis-A

Abstract

IT has previously been reported that the incidence of deformities of the skull, brain and palate in the young of female rats exposed to the effects of hypervitaminosis-A during pregnancy is greatly increased if large quantities of cortisone are given to the dams during the period of vitamin A administration1,2. It has also been shown that this ‘potentiating’ action of cortisone in relation to hypervitaminosis-A can be abolished by the administration of insulin to the pregnant female3.
