A cotton textile dried with various hygroscopic salts then contaminated with Staphylococcus epidermidis and dried again, showed remarkable reduction in viable bacterial cells. Of the salts investigated, sodium acetate was found to have the greatest antibacterial effect. Calcium chloride, magnesium chloride and magnesium sulfate, also showed some antibacterial effect. For sodium acetate, drying ...

Sodium and chloride are essential for numerous processes in the body including the regulation of osmotic pressure and acid-base balance. Both sodium and chloride also play important roles in the digestion and absorption of several nutrients from the gastrointestinal tract. Absorption of glucose and most amino acids from the small intestine requires an adequate supply of sodium. In cattle, magne...

A new procedure for production and purification of the thermophilic bacteriophage TP-84 in high yields is described. Cultures of Bacillus stearothermophilus strain 10, enriched with nutrients to obtain heavy growth and to prevent sporulation and maintained at a pH of 6.5, were infected with the phage in a 100-liter fermentor. Addition of magnesium chloride (0.01 M) and a temperature of 58-C we...

Plasma concentrations of calcium fractions, proteins, phosphate and magnesium were measured before, during and after cardiopulmonary bypass in 15 patients undergoing cardiac surgery. When calcium chloride was added to a pump priming solution which contained little or no blood, the concentrations of all calcium fractions were significantly greater after bypass than before, with a mean ionized ca...

The influence of osmolality on the effect of the novel beta-lactam antibiotic, mecillinam, on Escherichia coli was examined in a turbidimetric system. Both sucrose and sodium chloride were able to protect E. coli from the effects of mecillinam during the stage of conversion to morphologically abnormal forms, and the additional presence of small amounts of magnesium sulfate protected the spheric...

Fourteen cations were tested at a 1% concentration (wt:wt), as chlorides, for their effects on the biological activity of the gypsy moth, Lymantria dispar (L.), nuclear polyhedrosis virus (LdMNPV). Cupric chloride was toxic to gypsy moth larvae. Ferrous and ferric chloride were inhibitory to larval growth and development as well as to virus activity. Strontium chloride was inhibitory to virus a...

Renal tubular magnesium loss in association with a defect in tubular chloride reabsorption has been reported in Bartter’s and Gitelman’s syndromes. Clinically, both syndromes are characterized by hypokalaemic metabolic alkalosis, renal salt wasting, hyperreninaemic hyperaldosteronism and altered renal prostaglandin metabolism [1]. In Bartter’s syndrome, hypomagnesaemia occurs in 20% of patients...

In this study, the treatment of fly ash and steel making slag in aqueous ammonia chloride has been conducted. These zero-value wastes have distinctively high concentrations of magnesium, calcium and iron. The ammonium chloride has been employed as the leaching reagent to extract MgO out of fly ash and slag, and the dissolved cations in the leachate were subsequently precipitated by carbonation....
