title: [Magnesium and pregnancy].
abstract: Blood levels of total Mg, ionized Mg and intracellular ionized Mg of platelet were lowered in the 2nd trimester of gestation and thereafter. Urinary excretion of Mg does not change during the whole period of pregnancy. According to our results of animal experiments, intestinal absorption of Mg does not increase during pregnancy compared with non-pregnant state. These data suggest pregnant women tend to become magnesium deficiency. This is reflected in the fact that Mg metabolic parameters of pregnant women with preeclampsia are relatively reduced compared with those of healthy gravidae. In the obstetrical practice Mg has other significance, because magnesium sulfate is frequently used as a drug of choice in the therapy of threatened premature delivery and eclampsia. Mg plays important roles in physiology and pharmacology during gestation.
