title: The measurement of transplacental magnesium fluxes in the sheep.
abstract: Bi-directional transport rates of magnesium across the placenta of the ewe have been measured towards the end of pregnancy. The results indicated that approximately 0.042 and Mg/h/kg fetal body weight passed from ewe to fetus and that about 0.012 mg Mg/h/kg fetal body weight was transported back to the ewe. There was a significant, although small, positive gradient in plasma magnesium concentration from ewe to fetus.
