The article is devoted to the comparison of two approaches determining purity metal salts on example a complex in composition object - flotation potassium chloride. results mass fraction main component (potassium chloride) chloride obtained by direct (using coulometric titration method with correction for anions titrated determined ion and an excess cations) indirect (according scheme 100% minu...

The Jokoo-ION 150 AC is an automatic sodium, potassium and chloride analyser which uses ion-selective electrodes.The sample mode can be whole-blood, serum or urine. To evaluate a urine sample, a previous dilution (1:6) with the standard 1 solution is required. For three concentrations of control materials, the total precision (CV) ranged from 0.17 to 1.22% for sodium, 0.22 to 1.69% for potassiu...

Studies were carried out in normal male subjects (n = 6, age 20-35 years) to determine the interaction of angiotensin II and plasma sodium on aldosterone secretion. These relations were quantified by elevation of plasma sodium with an infusion of 5% sodium chloride (4 ml/kg/30 min i.v.) with measurements of plasma aldosterone, atrial natriuretic factor (ANF), and arginine vasopressin (AVP) over...

True values of Michaelis constants of the NADP+-specific isocitrate dehydrogenase from Halobacterium salinarium were not very different from those of the apparent constants reported by Aitken et al. (1970). The true constants were affected by salt in a similar manner to that of the apparent constants obtained with NADP+ at fixed concentrations of 1."0.2mM and threo-Ds-(+)-isocitrate at fixed co...

Patients with essential hypertension show impaired endothelium-dependent vasodilation induced by acetylcholine. Because dietary potassium supplementation increases endothelium-dependent relaxations to acetylcholine in hypertensive rats, we designed the present study to investigate whether potassium increases endothelium-dependent vasodilation in essential hypertensive patients. Therefore, in pa...

Chloride influx through GABA-gated chloride channels, the primary mechanism by which neural activity is inhibited in the adult mammalian brain, depends on chloride gradients established by the potassium chloride cotransporter KCC2. We used a genetic screen to identify genes important for inhibition of the hermaphrodite-specific motor neurons (HSNs) that stimulate Caenorhabditis elegans egg-layi...

From studies on the isolated gastric mucosae of amphibia and of the stomach in the intact mammal, there has emerged a simple description of the secretion of acid. There are two primary active transport systems, one for chloride and the other for the hydrogen ion. Chloride is transported somewhat more rapidly than the hydrogen ion. The difference between these two rates is substantially independ...

introduction: linguatula serrata is a zoonotic parasite, belonging to the class pentastomida. the major aim of this study was to evaluate the impact of sodium chloride (nacl) and heat on survival time of linguatula serrata nymphs. materials & methods: thirty nymphs (10 in triplicate) were separately transferred to plastic tubes, containing different concentrations of nacl solution (2%, 5% and 1...

Epidemiologic surveys, experimental studies in animals, and clinical trials in young and middle-aged patients with hypertension indicate that dietary potassium lowers blood pressure. The mechanism of the antihypertensive effect is not well defined. Variations in serum potassium within the physiologic range may directly affect vascular smooth muscle tone. Potassium may also influence the regulat...
