Recent Progress in Magnesium Research. Magnesium and pregnancy.
Summary of "Recent Progress in Magnesium Research. Magnesium and pregnancy."
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.

Medical and Biotech [MESH] Definitions
Magnesium chloride. An inorganic compound consisting of one magnesium and two chloride ions. The compound is used in medicine as a source of magnesium ions, which are essential for many cellular activities. It has also been used as a cathartic and in alloys.
Magnesium oxide (MgO). An inorganic compound that occurs in nature as the mineral periclase. In aqueous media combines quickly with water to form magnesium hydroxide. It is used as an antacid and mild laxative and has many nonmedicinal uses.
A nutritional condition produced by a deficiency of magnesium in the diet, characterized by anorexia, nausea, vomiting, lethargy, and weakness. Symptoms are paresthesias, muscle cramps, irritability, decreased attention span, and mental confusion, possibly requiring months to appear. Deficiency of body magnesium can exist even when serum values are normal. In addition, magnesium deficiency may be organ-selective, since certain tissues become deficient before others. (Harrison's Principles of Internal Medicine, 12th ed, p1936)
Inorganic compounds that contain magnesium as an integral part of the molecule.
A generic term for a variety of compounds that contain silicon, oxygen, and magnesium, and may contain hydrogen. Examples include TALC and some kinds of ASBESTOS.
