abstract：:Magnesium-deficient fetuses exhibited malformations (44%), anemia, and edema. Maternal plasma magnesium levels at day 21 of pregnancy reflected the level of dietary magnesium (2.43 +/- 0.09 mg Mg/100 ml, control; 0.74 +/- 0.02 mg Mg/100 ml, deficient). Plasma magnesium levels of deficient fetuses showed similar decrea...
