background in contemporary practice, acute mesenteric ischemia (ami) remains a serious cause of morbidity and mortality in abdominal emergencies. objectives we report the measurement of peritoneal fluid potassium and ph on a small series of rats that developed extensive ami following the surgical ligation of superior mesenteric vessels and compare the results with control groups. materials and ...

for investigation deficit irrigation and nitrogen application effect on nutrients uptake of henna ecotypes, this research was conducted in the form of split-split-plot on the basis of randomized complete block design with four replications in the research field of islamic azad university, jiroft, iran in 2013-2014. the main, sub and sub-sub plot were deficit irrigation (100, 75 and 50% of crop ...

vineyard management, plant nutrition, irrigation, genotype and pests and diseases are effective factors quantity and quality of crops. among mentioned factors, plant nutrition has more importance and nutrient imbalance in soil can affect crop quantity and quality. grape cluster necrosis at veraison time is important disorders in vineyard, because of lack of balance between potassium and magnesi...

the effects of different levels of nitrogen (100, 200, 300 and 400 mg/l) and potassium (125, 250 and 375 mg/l) on yield and leaf n and k concentrations of tomato were investigated in perlit culture using a factorial randomized design with three replications. the highest fruit yield was obtained with 200 mg/l n. higher levels of nitrogen decreased tomato yield. with increasing nitrogen concentra...

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...
