Potassium-free artificial sea water causes a loss of cell potassium and a gain of cell sodium in Porphyra perforata, which is not attributable to an inhibition of respiration. On adding KCl or RbCl to such low potassium, high sodium tissues, net accumulation of potassium or rubidium takes place, accompanied by net extrusion of sodium. Rates of potassium or rubidium accumulation and sodium extru...

background: nephrotoxicity is one of the major side-effects of cisplatin that has been seen in about 20% of treated patients. the aim of this study was to assess the effectiveness of a forced hydration protocol comprised of isotonic saline, potassium chloride (kcl) and magnesium sulfate (mgso4) on prevention of cisplatin nephrotoxicity. methods: this cross sectional prospective study was perfor...

OBJECTIVE It was suggested that prostaglandins which are synthesized by cyclooxygenase (COX) enzymes contribute to the actions of angiotensin-converting enzyme (ACE) inhibition and angiotensin AT1 receptor antagonism and there is an interaction between ACE signaling pathway and COX enzymes. We aim to investigate the role of COX enzymes in the effects of losartan, an angiotensin II (Ang II) rece...

introduction: abusing drugs such as morphine continues to be a serious medical and social problem. defining a habit that increases the devastating effect such as compulsive use and craving is necessary. methods: this experiment was designed in four groups 1) group-housed (gh) 2) isolation 3) group-housed morphine-treated (ghmt) (4) isolated-housed morphine-treated (ihmt). rats were received mor...

The aim of this study was to evaluate the effects of sodium chloride reduction and its substitution with potassium chloride on selected probiotic bacteria and their functionality in Akawi cheese during storage for 30 d at 4°C. The survival of selected probiotic bacteria (Lactobacillus acidophilus, Lactobacillus casei and Bifidobacterium longum) and starter bacteria (Streptococcus thermophilus a...

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...

Although leaf of Vitis vinifera (Vitaceae) has been used in traditional medicine to treat diarrhea, but no clinical and experimental studies have been conducted on its effects on the uterus. It has previously been reported that Vitis vinifera leaf extract reduces the ileum contractions induced by KCl and acetylcholine. The aim of the present study was to investigate the effect of Vitis vinifera...

The already marked tendency for functional food consumption, low in calories, and with biologically active properties, has been increasing. In this scenario, yacon tuberous roots, high levels of nutraceutical fructooligosaccharides, gain importance. However, these properties depend on fertilization management. Thus, our study aims to evaluate different doses potassium the physicochemical charac...

1. The non-radioactive cesium ion can replace the potassium ion almost quantitatively in solutions required for the development of the egg of the sea urchin into swimming blastulae. 2. Thorium chloride and uranium acetate cannot replace the potassium chloride in the solutions required for the development of the egg. 3. Thorium chloride and uranium acetate do not antagonize the action of the pot...

To determine the effects of potassium supplementation on endothelial function, cardiovascular risk factors, and bone turnover and to compare potassium chloride with potassium bicarbonate, we carried out a 12-week randomized, double-blind, placebo-controlled crossover trial in 42 individuals with untreated mildly raised blood pressure. Urinary potassium was 77+/-16, 122+/-25, and 125+/-27 mmol/2...
