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 ...

One mechanism of salt taste transduction by gustatory receptor cells involves the influx of cations through epithelial sodium channels that can be blocked by oral application of amiloride. A second mechanism is less clearly defined but seems to depend on electroneutral diffusion of the salt through the tight junctions between receptor cells; this paracellular pathway is insensitive to amiloride...

Sodium saccharin, ascorbate and other sodium salts fed at high doses to rats produce urinary bladder urothelial cytotoxicity with consequent regenerative hyperplasia. For sodium salts that have been tested, tumor activity is enhanced when administered either alone or after a brief exposure to a known genotoxic bladder carcinogen. These sodium salts alter urinary composition of rats resulting in...

Interaction of homologous fatty acids (C3-C18) with sodium deoxycholate was investigated. From NMR and ultrasonic results it was found that short chain homologues (up to C9) do not participate in the formation of mixed micelles with sodium deoxycholate. Fatty acid homologues with longer chains (starting with C9) form mixed micelles by "burying" hydrophobic chains in hydrophobic environment of a...

A simple and efficient one-pot method for the preparation of aromatic iodides has been developed by sequential diazotization–iodination of aromatic amines employing sodium nitrite and sodium iodide in the presence of acidic ionic liquid N-methyl-2-pyrrolidonum hydrosulfate ([H-NMP]HSO4). The diazonium salts that are formed by this ionic liquid are stable at room temperature and r...

Buccal bioadhesive bilayer tablets of prochlorperazine maleate were designed and formulated by using buccoadhesive polymers such as hydroxypropylmethyl cellulose, Carbopol 934P, and sodium alginate. Physicochemical characteristics like the uniformity of weight, hardness, thickness, surface pH, drug content, swelling index, microenvironment pH, in vitro drug release, and in vivo buccoadhesion ti...

The solubility of cholesterol in mixed aqueous ionic and non-ionic micellar systems in the presence and absence of salts and ionic dyes has been studied. The mixed micellar system of cetyl trimethyl ammonium bromide and Triton X-100 solubilized more cholesterol than a system consisting of sodium dodecyl sulfate and Triton X-100. The influence of salts and dyes on these systems was moderate but ...

Two conjugated bile salts (10 mmol/l sodium glycocholate, 10 mmol/l sodium taurodeoxycholate) and three laxatives (30 mmol/l magnesium sulphate, 10 mmol/l ricinoleic acid, 2 mmol/l dioctyl sodium sulphosuccinate) were tested on seven subjects with no intestinal lesions in 14 experiments by intestinal perfusion of the jejunum. A 25 cm segment was studied. Each solution was perfused at the rate o...

The range of sodium chloride (salt)-to-moisture ratio is critical in producing high-quality cheese products. The salt-to-moisture ratio has numerous effects on cheese quality, including controlling water activity (a(w)). Therefore, when attempting to decrease the sodium content of natural cheese it is important to calculate the amount of replacement salts necessary to create the same a(w) as th...

Rapid chemical analysis of plant and soil extracts for plant nutrients is beingv given widespread attentioii. Potassium is one of the most important and expensive planit nutrienits and requires, therefore, special coiisideration of methods employed for determining, its coneentrations in soils and plant tissues. The cobaltiniitrite iimetlhod for potassiumi deteriliinations in extracts of soils a...
