Phosphorus-31 magnetic resonance spectroscopy was used in 2-day (n = 4) and 40-day (n = 4) miniswine to determine whether plasma hypermagnesemia alters brain intracellular magnesium concentration and if the plasma-brain intracellular magnesium relationship changes with age. At control, brain intracellular magnesium concentration was similar in the 2-day (0.24 +/- 0.04 mM) and 40-day groups (0.21 +/-...

The mechanism or mechanisms accounting for this reduction remain unclear but may be related to PIH itself, medications used to treat the mother (e.g., magnesium sulfate), or to obstetrical management. In this retrospective...
