Whereas in the general population magnesium deficits are most often thought to result mainly in calf cramps (which are generally not considered to be life threatening), it is less well known that a magnesium deficit induced by a magnesium-deficient diet in humans resulted in severe cardiac arrhythmias [5] . Other studies as, for example, an epidemiological study in Germany showed that low serum...

1. Respiratory alkalosis accompanies the clinical syndrome of tetany, precipitates cardiac arrhythmias and predisposes to coronary vasoconstriction. Magnesium plays a critical role in the maintenance of membrane function, and magnesium depletion is often associated with cardiac arrhythmias or vasoconstriction. 2. As technology for detecting circulating ionized magnesium (the most interesting fo...

OBJECTIVE Magnesium deficiency has been associated with insulin resistance (IR) and increased risk for type 2 diabetes in adults. This study was designed to determine whether obese children exhibit serum or dietary magnesium deficiency and its potential association with IR. RESEARCH DESIGN AND METHODS We studied 24 obese nondiabetic children (BMI > or =85th percentile) and 24 sex- and puberty...

magnesium is extracted with a chloroform solution of n-p-tolyl-2- thenohydroxamic acid (pttha) from aqueous solution of ph 9.5 .mg-pttha complex is colourless and the colour is developed by adding quinalizarin into the extract. lmax and e of the complex are 590nm and 2.8´103 lmol -1cm-1respectively.most common  ions do not interfere in the determination of magnesium. the spectral characteristic...

BACKGROUND Because magnesium blocks the N-methyl-D-aspartate receptor and its associated ion channels, it can prevent central sensitization caused by peripheral nociceptive stimulation. However, transport of magnesium from blood to cerebrospinal fluid (CSF) across the blood-brain barrier is limited in normal humans. The current study was designed to evaluate whether perioperative intravenous ma...

Based on dietary intake recommendations, magnesium deficiency commonly occurs throughout the world. However, widespread pathological conditions induced by dietary magnesium deficiency have not been identified. This discrepancy may be caused by other dietary factors ameliorating or exacerbating the response to a marginal magnesium deficiency and/or the length of the deficiency. Thus, a study was...

BACKGROUND Magnesium is one of the most important minerals in the body. Although some studies reported that patients with cystic fibrosis (CF) lack magnesium, no international study has assessed the importance of oral magnesium supplementation in CF patients. OBJECTIVE We prospectively investigated the long-term effect of oral magnesium supplementation on respiratory muscle strength by using ...

Twenty patients, who underwent coronary revascularization without cardioplegic arrest, were given (during cardiopulmonary bypass) either magnesium chloride 16 mmol in 10 ml of water (magnesium group) or 10 ml of water alone (control group). Plasma and urinary magnesium concentrations were measured for 24 h after operation. ECG was recorded continuously during this period. QT intervals corrected...
