A large steel evaporator used for magnesium chloride soln was shut down for maintenance. During maintenance operations a fatality occurred from atmospheric oxygen deficiency inside the evaporator. It was found later that the oxygen content in the evaporator fell from the nomral 21% to about 1% in under 24 hr, & this was confirmed in lab tests. This was attributed to very rapid rusting of the steel under warm humid conditions in the presence of traces of magnesium chloride. Further work shows that ... presence of scale is a contributory factor. Magnetite scale (Fe3O4) on mild steel increases the depletion rate by a factor of 10, while the rust formed during the corrosion has little effect.

In humid environments it causes steel to rust very rapidly.

Magnesium chloride (ip) administered simultaneously with Neguvon (ip) decreased the lethal effects of Neguvon, however, this was not observed with magnesium aspartate.

The effects of intracerebroventricular administration of calcium or magnesium on the blood pressure regulation in the brain were investigated. The systolic blood pressure in spontaneously hypertensive rats (male, 13-wk-old) was decreased by calcium chloride (100 ug/rat) and increased by magnesium chloride (20, 100, or 500 ug/rat). The depressor response induced by calcium was inhibited by magnesium chloride in a dose-dependent manner. Combining these results with those previously reported, it is suggested that magnesium inhibits the ability of calcium to reduce blood pressure through calmodulin- and dopamine-dependent functions in the brain.

Three adult male squirrel monkeys that were trained to respond on a 3-min fixed-interval schedule of food reinforcement were injected with various doses of magnesium chloride (MgCl(2), 30 and 100 mg/kg), cocaine (0.03-3.0 mg/kg), and their combination. ...MgCl(2) had little effect on responding during the 2 hr sessions. Low doses of cocaine (0.03-0.1 mg/kg) were ineffective, intermediate doses (0.1-1.0 mg/kg) increased responding, and high doses (1.0-3.0 mg/kg) decreased responding. When MgCl(2) was combined with intermediate doses of cocaine, the rate-increasing effects of cocaine were attenuated. Less reliably, increased rates of responding were sometimes observed when MgCl(2) was combined with low (ineffective) or high (rate-decreasing) doses of cocaine. These interactions depended both on the time following injection and the dose of MgCl(2) and showed marked individual differences. These effects observed in monkeys are similar to some of the interactions previously reported in rodents.

...In Ca-free soln, maintained contractions /in estrogen-dominated rat uterus/ induced by oxytocin and vanadate are augmented by Mg2+ /(administered as MgCl2)/.

Magnesium is approx 2% of the earth's crust, eighth in elemental abundance, and widely distributed in the environment as a variety of compounds(1,2). Its concn is 1.8% and 1.6% in igneous and sedimentary rocks, respectively(2). In igneous rocks, magnesium is typically a constituent of the dark-colored ferromagnesium minerals (e.g., olivine, pyroxenes, amphiboles, and dark-colored micas), along with other less common minerals(2). In metamorphic rocks, magnesium minerals such as chlorite, montmorillonite, and serpentine occur(2). Sedimentary rocks of magnesium include carbonates (e.g., magnesite and hydromagnesite), hydroxides (e.g., brucite), and mixtures of magnesium and calcium carbonate (e.g., dolimite)(2). Magnesium is also found in silicate minerals (e.g., olivine, serpentine, and asbestos)(1). Rocks and minerals contain a higher percentage of magnesium than do soils as a result of the loss of magnesium due to weathering(1). Magnesium chloride, with makes up 17% of sea salt(1) is released to the atmosphere as sea spray(SRC).

The production and use of magnesium compounds as refractories, as chemical intermediates, and in construction materials(1,2) result in their release to the environment through various waste streams(SRC). The production and use of magnesium compounds in environmental applications and in agriculture(1,2) results in their direct release to the environment(SRC). About 69% of the magnesium compounds used in the United States were used for refractories (e.g., olivine)(1). The remaining 31% of magnesium compounds were used in agriculture as fertilizer or animal feed (e.g, magnesium oxide, magnesium sulfate), as chemical intermediates (e.g., magnesium chloride, magnesium hydroxide, magnesium carbonate, magnesium oxide) , construction materials (e.g., magnesium oxide), environmental (e.g., magnesium oxide, magnesium hydroxide), and industrial applications (e.g., magnesium oxide)(1,2). Other uses include road dust and ice control (e.g., magnesium chloride), pulp and paper applications (e.g.,magnesium sulfate), pharmaceuticals (e.g., magnesium sulfate, magnesium carbonate, magnesium oxide), and cosmetics (e.g., magnesium carbonate)(1,2).

/LABORATORY ANIMALS: Acute Exposure/ The effect of magnesium chloride on the ventricular fibrillation threshold (VFT) and the threshold for the ventricular premature contraction (VPCT) was studied in 20 dogs. Seven of the dogs were pre-treated with digitalis and four were in the form of heart-lung preparations. In the anesthetized, intact dogs, the VPCT was 0.19 +/- 0.01 mV. After treatment with magnesium chloride (100 mg/kg iv), the VPCT increased by 53% (P<0.01). In the same group of animals, the VFT averaged 0.50 +/- 0.06 mV., which more than doubled after administration of magnesium. The threshold of VPCT in the digitalis-treated dogs measured 0.18 +/- 0.01 mV; this value doubled after magnesium. The VFT in the digitalized dogs also increased after magnesium; however, resistance to electrical defibrillation was encountered in this group. In the heart-lung preparations, VPCT improved by 72% and a gain of 131% in the VFT followed magnesium administration. The results suggest that magnesium increases the ventricular threshold of arrhythmias in normal, denervated (heart-lung preparations) and also digitalis-treated hearts... .

/LABORATORY ANIMALS: Acute Exposure/ The minimum concn of K and Mg in cardioplegic solution to get cardiac arrest was studied. The isolated rat hearts were perfused by Langendorf perfusion with modified Krebs-Henseleit bicarbonate buffer solution, and their heart rates were measured. The perfusion of infusate of 15 mM/l of K-aspartate stopped the heart beat completely; it took 25 mM/l of magnesium chloride to get cardiac arrest. By their combination, however, heart was arrested with infusate of 10 mM/l of K-aspartate and 15 mM/l of magnesium chloride, which were lower concn than K-aspartate or magnesium chloride alone.

Magnesium is important as a cofactor in many enzymatic reactions in the body involving protein synthesis and carbohydrate metabolism (at least 300 enzymatic reactions require magnesium). Actions on lipoprotein lipase have been found to be important in reducing serum cholesterol and on sodium/potassium ATPase in promoting polarization (eg, neuromuscular functioning).

Mechanism of action of magnesium chloride studied in 10 adult volunteers. Results suggested magnesium ion in duodenum is relatively weak stimulus to pancreas and gall bladder. It is weak stimulant to cholecystokinin release and inhibits net jejunal water absorption. The oral administration of a single 800 mg dose of magnesium chloride in healthy volunteers resulted in a diminished rate of intraluminal lipid and protein digestion. The most pronounced effect of magnesium chloride, however, was a decreased gastric emptying rate of both test meals. After correction for gastric emptying, no differences were noted in intraluminal lipid or protein digestion. Therefore, the lower lipid levels noted after magnesium supplementation are unlikely to be the result of altered lipid assimilation. Magnesium chloride slows gastric emptying but does not influence lipid digestion.

...Three mature ewes each received by intrarumenal infusion a supplement of 0, 1, 2 and 3 g Mg/d in sequence over four 10-day periods. Net Mg absorption distal to the pylorus took place down its electrochemical gradient, although the quantity absorbed remained small during the control and first infusion periods. The bulk of Mg absorption occurred before the pylorus and, during the control and first infusion periods, took place against its electrochemical gradient. The net Mg absorption proximal to the pylorus rose with declining efficiency as Mg intake was increased. It is suggested that saturation of the absorption process at this site was occurring.
