Abstract
Summary
A marked increase in resorption of the embryos and placentae was observed following administration of high doses of ethionine to pregnant rats. A similar dose of methionine had no apparent effect by itself while a combination of methionine with ethionine resulted in about a 50% reduction in the resorptive effect of ethionine. The sequential destruction of the tissues of placenta and embryo associated with the ethionine-induced resorption is described.
