O.  aThe placental transmission of selenium in sheep.h[electronic resource]  c1966  aAbstract: The placental transmission of selenium was investigated in thirteen ewes during late gestation. The ewes were injected either with Se75-sodium selenite, Se75(L)-selenocystine or Se75 (L)-selenomethionine. Twelve lambs and nine ewes were killed soon after delivery and the Se75-concentration was measured in the tissues of the lambs and ewes. The Se75-concentration in the tissues of the lambs was about half that of the ewes when they were injected with selenite. This indicates that the placenta constitutes to a certain extent a barrier for the passage of inorganic selenium. Se75-selenomethionine and Se75-selenocystine were more easily transferred across the placenta than Se75-sodium selenite. When the selenite dose was increased ten times the selenium uptake in milligrams per gram tissue in the lambs increased 5?8 times.  aAnimal reproduction  aEwes  aLambs  aPregnancy  aSelenium  aSheep  aFisiologia  aOvino  aReprodução  aGestacao  aGestation  aIn Vitro Techniques  aMaternal fetal exchange1 aOKSANEN, H.
