A simple and rapid procedure has been developed for the complexometric titration of serum calcium and magnesium using "plasmocorinth B" as indicator. Both determinations can be carried out from the same 0.5 ml. sample. The method is in good agreement with the established calcium and magnesium methods.

Ghazali, S., and Barratt, T. M. (1974). Archives of Disease in Childhood, 49,97. Urinary excretion of calcium and magnesium in children. Urine calcium excretion in healthy children was 2 38±0 66 (SD; no. 52) mg/kg per 24 hr and urinary magnesium excretion was 2 82±0 79 (SD; no. 23). The 24-hour urine calcium excretion could be predicted with reasonable confidence from the calcium/ creatinine co...

We report a 30-yr-old lady who was being treated as postpartum psychosis. Patient had generalized tonic clonic convulsions and was found to have bilateral cataract. Her serum calcium, serum magnesium and serum parathyroid were low. On correction of serum magnesium her PTH did not increase. She was hence diagnosed as primary hypoparathyroidism. On correction of her serum calcium her psychosis im...

It is generally accepted that magnesium requirements increase in the elderly. Multiple reasons for this exist. In the elderly, magnesium intake tends to be low, intestinal absorption is frequently diminished, and urinary output is often enhanced. As a result, the magnesium status of aging subjects is likely to be marginal, if not frankly deficient. Because magnesium plays important roles in art...

the results obtained in the present investigations point to a definite correlation between the onset of myocardial injury, electrocardiographic changes and biochemical changes. changes in the electrocardiogram and elevated serum levels were paralleled by an increased excretion of magnesium in urine as early as one hour. serum calcium and serum potassium levels did not show any significant resul...

background: minerals are essential materials in animal reproduction. the determination of these elements is valuable in relation to different conditions in arabian horses. objectives: the purpose of this study was to evaluate the effects of pregnancy on certain macro and micro minerals in arabian horses. methods: blood samples were collected from one hundred apparently healthy mares from differ...

In an effort to study the relation of magnesium to other inorganic salt metabolism, three diseases other than hyperparathyroidism come to mind. The thyroid gland has been shown to exert an enormous influence on calcium metabolism, and in exophthalmic goiter, even though the blood calcium level is normal, there is the largest calcium excretion found in any disease (1). In steatorrhea is found a ...

An experimental study was conducted to determine the effects of the leaching parameters on impurity ion concentrations of the liquid phase in ulexite leaching. Powdered ulexite ore was leached in an aqueous medium with sulfur dioxide. The Taguchi experimental design approach and statistical methods were used to evaluate the effects of the leaching parameters (solid/liquid ratio, temperature...

The thermophilic Geobacillus bacterium catalyzed the formation of 100-μm hexagonal crystals at 60°C in a hydrogel containing sodium acetate, calcium chloride, and magnesium sulfate. Under fluorescence microscopy, crystals fluoresced upon excitation at 365 ± 5, 480 ± 20, or 545 ± 15 nm. X-ray diffraction indicated that the crystals were magnesium-calcite in calcite-type calcium carbonate.

To investigate the correlations among seminal plasma Magnesium (Mg), Phosphorus (P), Potassium (K), Calcium (Ca), Chromium (Cr), Manganese (Mn), Iron (Fe), Copper (Cu), Zinc (Zn), Selenium (Se), Molybdenum (Mo) and Iodine (I) concentrations and semen parameters [1– 15]. 500 fertile and 1000 infertile males provided a standardized semen specimen. Total Magnesium (Mg), Phosphorus (P), Potassium (...
