Germ-free (GF) and conventional (CV) adult rats were given for 4 weeks a semi-synthetic diet containing 10 p. 100 lactose (L) or no lactose (LO). The axenic state had an unfavourable effect on sodium and potassium absorption. On the contrary, it increased the absorption and retention of calcium, phosphorus and magnesium. The favourable effect of lactose on magnesium metabolism was not different...

Introduction: Calcium critical limit in pistachio plants is about 1.3 percent of plant dried material; magnesium critical limit in pistachio leaves is about 0.6 percent of plant dried material. To measure calcium and magnesium there are several methods in which three methods of titration and atomic absorption that are more common and used to libraries more in addition to ICP modern method are u...

Magnesium deficiency is frequently associated with hypokalemia. Concomitant magnesium deficiency aggravates hypokalemia and renders it refractory to treatment by potassium. Herein is reviewed literature suggesting that magnesium deficiency exacerbates potassium wasting by increasing distal potassium secretion. A decrease in intracellular magnesium, caused by magnesium deficiency, releases the m...

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...

PURPOSE Exposure to the microgravity environment of space increases the risk of kidney stone formation, particularly for calcium oxalate and uric acid stones. This study was performed to evaluate the efficacy of potassium alkali as potassium-magnesium citrate in reducing renal stone risk and bone turnover. MATERIALS AND METHODS This study was performed as a double-blind, placebo controlled tr...
