title: [Study of magnesium and calcium levels of plasma and within erythrocyte before and after magnesium sulfate treatment in patients with pregnancy induced hypertension].
abstract: OBJECTIVE
  To study the changes of calcium and magnesium levels in patients with pregnancy induced hypertension (PIH) and the therapeutic effect of magnesium sulfate (MgSO4).
  
  
  METHODS
  The calcium and magnesium levels in plasma and erythrocytes of 36 patients with PIH and 14 healthy gravidi in their late pregnancy were determined and the changes after 4 hours infusion of MgSO4 as well.
  
  
  RESULTS
  Plasma calcium decreased significantly in moderate and severe PIH patients, but calcium increased and magnesium decreased in their erythrocytes. After MgSO4 infusion for PIH, magnesium levels in both plasma and erythrocytes increased, while calcium increased in plasma and decreased in erythrocyte to normal levels.
  
  
  CONCLUSIONS
  Magnesium deficiency is the basis of calcium and magnesium disturbances in PIH, and MgSO4 treatment may improve the situation effectively.
