Magnesium in biology be used as adjuvant therapy in patients on optimal treatment for severe congestive heart failure, increasing survival rate and improving clinical symptoms and patient's quality of life. Magnesium can affect muscle relaxation through direct action on cell membranes. Mg ions close certain types of calcium channels, which conduct positively charged calcium ions into neurons. With an excess of magnesium, more channels will be blocked and nerve cells activity will decrease. Intravenous magnesium sulphate is used in treating pre-eclampsia. For other than pregnancy-related hypertension, a meta-analysis of 22 clinical trials with dose ranges of 120 to 973 mg/day and a mean
Magnesium hydroxide formation of expansive brucite. This reaction, one of the two main alkali-aggregate reaction (AAR) is also known as alkali-carbonate reaction. Magnesium hydroxide Magnesium hydroxide is the inorganic compound with the chemical formula Mg(OH). It occurs in nature as the mineral brucite. It is a white solid with low solubility in water (). Magnesium hydroxide is a common component of antacids, such as milk of magnesia, as well as laxatives. Combining a solution of many magnesium salts with alkaline water induces precipitation of solid Mg(OH): On a commercial scale, Mg(OH) is produced by treating seawater with lime (Ca(OH)). 600m of seawater
