hypokalemic disease is a disorder in which the amount of serum’ s potassium declines and the patient faces limbs weakness. in this disease, eye muscle and respiratory muscles rarely become involved and death may follow due to respiratory paralysis and heart conducting disturbances. since this disease is treatable and progressive weakness can be prevented, therefore in the study conducted we att...

BACKGROUND Primary hyperaldosteronism may be associated with elevated 24-hour urinary potassium excretion. We evaluated the diagnostic value of spot urine (SU) potassium as an index of 24-hour urinary potassium excretion. METHODS We measured SU and 24-hour urinary collection potassium and creatinine in 382 patients. Correlations between SU and 24-hour collections were assessed for potassium l...

AIMS Potassium homeostasis is essential for normal myocardial function, and low serum potassium may cause fatal arrhythmias. However, the association of low potassium and long-term mortality and morbidity in heart failure (HF) is largely unknown. METHODS AND RESULTS We studied 6845 HF patients in the Digitalis Investigation Group trial with serum potassium levels < or =5.5 mEq/L. Of these, 11...

this research was carried out to investigate the effect of different levels of potassium (in nutrient solution), harvest season and plant density on yield and quality of strawberry cv. selvain hydroponic system conditions. the tests were done in the greenhouse, and laboratories of horticultural science department of the university colleg of agriculture and natural resources of tehran university...

ATP-sensitive potassium (KATP) channel openers have a relaxation effect due to the lower cellular membrane potential and inhibit calcium influx. There has been considerable interest in exploring KATP channel openers in the treatment of various diseases such as cardiovascular, cerebrovascular, and urinary system disease and premature labor. The purpose of this study was to synthesize 3,3,6,6-tet...

in order to study of yield and qualitative characteristics of potato (aola variety), an experiment was conducted in mashhad conditions under irrigation regims and different levels of potassium fertilizer. this experiment was based on randomized copmpletely block with split plot design with three replications in khorasan razavi agricultural and natural resource research center in 2010. three lev...

to study the effect of different concentrations of potassium in thenutrient solution and water stress on the quality and quantity yield of lilium la cv.termoli, a pot experiment was conducted based on completely randomized design in sand and perlite medium (50:50) in three levels of potassium (kfree, 6 mm k and and 12 mm k in hoagland solution) with three replications. in the present study, the...

We evaluated the effect of a low potassium diet on blood pressure in normotensive (NT) and in borderline hypertensive subjects (BHT). There were 11 BHT men (age, 24.6 +/- 1.2 years) and 10 NT men (age, 23.5 +/- 1.0 years). Subjects were studied while on both low potassium, high sodium (30 meq/day, 400 meq/day) diets and high potassium, high sodium (100 meq/day, 400 meq/day) diets, each taken fo...

Potassium in plants accounts for up to 10% dry weight, and participates in different physiological processes. Under drought stress, plant requires more potassium but potassium availability in soil solutes is lowered by decreased soil water content. Forming symbiosis with arbuscular mycorrhizal (AM) fungi not only enlarges exploration range of plant for mineral nutrients and water in soil, but a...
