Clinical studies have shown that topiramate, a sulphamate-substituted fructopyranose derivative, might be an efficacious treatment for alcohol dependence, smoking cessation within an alcohol-dependent population, and cocaine dependence. Mechanistically, topiramate's therapeutic effects have been hypothesized to be due to inhibition of cortico-mesolimbic dopamine function, the primary substrate ...

background there has not been any published literature in iran about the evaluation of hemodialysis patients’ knowledge in relation to dietary sources of protein, phosphorus, potassium, sodium and fluids. objectives therefore, the present study was performed with this aim, in patients with renal failure treated with hemodialysis. patients and methods fifty hemodialysis patients were recruited. ...

abstract this study was carried out in farm of dehkhoda institute (2013-2014). the study was done as randomized complete blocks design with five potassium sulfate amounts (0, 50, 100, 150 and 200 kg/ha) and four replications. according to results, potassium affected the number of stalk numbers, yield, and the amount of obtainable sugar (p<0.01) and purity (p<0.05). the highest stalk numbers (18...

Intracellular potassium activity in guinea pig left atria was measured using potassium ion-selective microelectrodes and conventional microelectrodes. The effects of extracellular potassium concentration and acetylcholine on both intracellular potassium activity and the relationship between the resting membrane potential and the potassium equilibrium potential were investigated. Intracellular p...

1. The effect of extracellular potassium on the transport of sodium and potassium in rat thymocytes has been studied in vitro. 2. A significant increase in the rate constant for total and ouabain-sensitive sodium efflux was demonstrated at an extracellular potassium concentration of 1 mmol/l as compared with that at either 0 or 2 mmol/l. 3. At potassium concentrations below 3 mmol/l ouabain-sen...

this study was conducted under ahvaz, iran environmental condition during 2012 and 2013 growing seasons in order to investigate the influence of foliar application of potassium on some physiological and biochemical characteristics of three olive cultivars including ‘mission’, ‘koroneiki’ and ‘dezfuli’. potassium sulfate in different concentrations of 0, 1, and 2 g l-1 was sprayed twice on selec...

Randomized trials have shown that increasing potassium intake lowers blood pressure. However, most previous trials used potassium chloride, whereas potassium in fruits and vegetables is not a chloride salt. It is unclear whether a nonchloride salt of potassium has a greater or lesser effect on blood pressure compared with potassium chloride. We performed a randomized crossover trial comparing p...

1. Potassium depletion was induced in rabbits with frusemide and measurements were made of plasma, leucocyte, erythrocyte and total exchangeable potassium before and during potassium depletion. 2. All measurements, except erythrocyte potassium expressed as mmol/kg of cells, decreased during the depletion period. 3. Significant correlations were observed between change in leucocyte potassium and...
