One hour after administration of potassium chloride to potassium-deficient rats, the depressed peripheral vascular response to pressor substances was significantly elevated. Administration of potassium chloride to potassium-deficient rats also returned to higher levels the lowered blood pressure of previously normotensive, as well as hypertensive rats. It appears that the depressor effect of po...

forward osmosis (fo) has recently drawn attention as a promising membrane based method for seawater and brackish water desalination. in this study, we focus on the use of calciun chloride (cacl2) and potassium bicarbonate (khco3) as inorganic salt draw solution candidates due to their appropriate performance in water flux and reverse salt diffusion as well as reasonable cost. the experiments we...

abstract the use of plants for remediation of heavy metals contaminated soils is an economical, cheap and effective strategy. this research was conducted in order to study the effect of potassium chloride on cadmium uptake and enhancement of it's phytoremediation by canola (brassica napus l.) and sunflower (helianthus annuus l.) in a cadmium polluted soil from angoran in zanjan province. in a r...

The purpose of this study was to investigate the factors controlling membrane permeability to potassium of smooth muscle cells from rat aorta stimulated by depolarization. The increase 42K+ efflux (change in the rate constant) induced by depolarization (application of high concentrations of potassium chloride) was inhibited significantly by the calcium antagonists diltiazem and nisoldipine. Par...

THE EFFECT OF EXPOSING RABBIT RETICULOCYTE RIBOSOMES TO CONCENTRATED SOLUTIONS OF POTASSIUM CHLORIDE WAS EXAMINED BY: (a) dialysis against 0.5m-potassium chloride; (b) zone centrifugation through a sucrose gradient in 0.5m-potassium chloride; (c) differential centrifugation of a solution made 0.5m with respect to potassium chloride. The products of each treatment and their ability to support pr...

Obligatory, coupled cotransport of Na(+), K(+), and Cl(-) by cell membranes has been reported in nearly every animal cell type. This review examines the current status of our knowledge about this ion transport mechanism. Two isoforms of the Na(+)-K(+)-Cl(-) cotransporter (NKCC) protein (approximately 120-130 kDa, unglycosylated) are currently known. One isoform (NKCC2) has at least three altern...

1. The inter-relationships between plasma aldosterone, plasma renin activity, potassium excre­ tion and plasma potassium were evaluated in subjects with normal and decreased glomerular filtration rate. 2. In seven studies of healthy control subjects and 12 studies of patients with renal disease, daily urine collections, plasma aldosterone and plasma renin activity were measured on a free diet f...

Intact human erythrocytes can be readily loaded with calcium by incubation in hypersomotic media at alkaline pH. Erythrocyte calcium content increases from 15-20 to 120-150 nmol/g hemoglobin after incubation for 2 h at 20 degree C in a 400 mosmol/kg, pH 7.8 solution containing 100 mM sodium chloride, 90 mM tetramethylammonium chloride, 1 mM potassium chloride, and 10 mM calcium chloride. Calciu...

The rapid proliferation of fertigation in modern agriculture has brought about a growing demand for factory mixed fertilizer solutions, as well as wide-scale dissolution of solid fertilizers by farmers in the field. Rules of chemistry and physics control the rate of dissolution and, hence, the nutrient content in the fertilizer solution. Potassium chloride (KCl) is the cheapest potassium-contai...
