BACKGROUND Adrenaline release and excess insulin during hypoglycemia stimulate the uptake of potassium from the bloodstream, causing low plasma potassium (hypokalemia). Hypokalemia has a profound effect on the heart and is associated with an increased risk of malignant cardiac arrhythmias. It is the aim of this study to develop a physiological model of potassium changes during hypoglycemia to b...

BACKGROUND Hyperkalemia is a potentially life-threatening complication resulting from the use of angiotensin-converting enzyme (ACE) inhibitors; data to guide the intensity of monitoring for or responding to hyperkalemia in outpatients are limited. METHODS Case-control methodological procedures were used to identify risk factors for hyperkalemia. Outpatients prescribed ACE inhibitors during 1...

persian shallot (allium altissimum regel.) is one of the perennial medicinal and industrial plant which is naturally growing in high elevated lands. in order to evaluate the effects of different nutrient elements such as nitrogen, phosphorus and potassium on photosynthetic rate and pigment content of persian shallot; an experiment was conducted as factorial based on completely randomized design...

makes multiple tracer studies more complicated." In reply to their query the method used to measure the loss of potassium from the dialysate, which was 150 mEq in my series', was a direct measurement. The statement by them that: "there is a wide range of potassium status in patients with chronic renal failure being maintained with haemodialysis" contradicts their next statement that: "The absen...

This communication undertakes to clarify a complex association between potassium distribution and amino acid transport. The transfer of amino acids into cells occurs best over a rather narrow range of extracellular potassium ion concentration (l-4). Furthermore, the uptake of neutral amino acids provokes a somewhat less than stoichiometric loss of potassium from the cells, with sodium ion repla...

Hypokalaemia is a common clinical problem. It can lead to severe disturbances in cardiac, neurological and muscle function. We present the case of a 45-year-old woman who was transported to our hospital with cardiac arrest following ventricular fibrillation. Blood sampling revealed severe acidosis (pH 7.02) and extreme hypokalaemia (0.9 mmol/l). The low serum potassium level was most likely cau...

UNLABELLED As the renal function progressive decline is often correlated to diuresis impairment, potassium level changes represent a major pathophysiological factor in monitoring chronic kidney disease. Even more, potassium level imbalance could lead to life-threatening situations with the risk of severe rhythm disorders appearance. The aim of the study was to determine in which degree the seru...

The intracellular potassium content of perfused rat heart was measured by potassium-39 nuclear magnetic resonance (NMR) spectroscopy at 33 degrees C with an inversion recovery technique based on the fact that the spin-lattice relaxation time (T1) of the intracellular potassium (8.3 msec at 8.45 T) is much faster than that of the extracellular potassium (68 msec). Intracellular potassium decreas...

A model has been used to simulate potassium (K) uptake by wheat in a pot culture experiment. Three soils from India, namely Alfisol, Inceptisol and Vertisol, were differentially K exhausted by Sudan grass (Surghum vulgare var. Sudanensis) for a period of 280 days and were used to simulate potassium uptake by wheat (Triticum aestivum) and also to predict the amounts of K released or fixed during...

Errors in potassium measurement can lead to falsely elevated potassium level that is pseudo hyperkalemia. Usually these errors are recognized either by the clinicians or laboratory personals. The factors which causes pseudo hyperkalemia can mask hypokalemia by pushing low value to normal value, which is very difficult identify by laboratory personals. In this article we are discussing the cause...
