Potassium channels are integral membrane proteins that selectively transport K+ across the cell membrane. They are present in all mammalian cells and have a wide variety of roles in both excitable and nonexcitable cells. The phenotypic diversity required to accomplish their various roles is created by differences in conductance, the timecourse and ...

Clinical and Experimental Pharmacology and Physiology, 1989
The maintenance of potassium homeostasis with an increased potassium intake or decreased renal function is dependent in part on the renal adaptation observed in 'potassium tolerance'. However other factors, including control of ingestion, and increased distal delivery of fluid, also play a role.

Inflammation, 1988
Membrane depolarization is an early event in cell stimulation. Since the resting membrane potential is dependent on the potassium composition of the extracellular medium, we investigated whether there are clinical situations in which potassium levels are high enough to depolarize polymorphonuclear leukocytes.

Advances in Kidney Disease and Health
Potassium homeostasis is essential for maintaining the normal resting membrane potential of excitable cells. Yet daily dietary potassium typically far exceeds total extracellular potassium, thus the body has elegant strategies to shift potassium into cells promptly after a meal and then the kidneys efficiently excrete potassium.

Australian and New Zealand Journal of Medicine, 1977
Potassium balance is regulated by appropriate changes in potassium excretion in the distal portion of the nephron. By contrast, potassium intake, absorption and proximal renal reabsorption do not show regulatory variation. Extracellular potassium concentration, which is a critical factor in membrane polarization, may at times vary in a direction ...

Potassium Hydroxylamine Complexes
Inorganic Chemistry, 2008Potassium complexes of N,N-dialkylhydroxylamines [KONR2, R=Me (1a), iPr (2a), CH2C6H5] were synthesized by the deprotonation of the corresponding N, N-dialkylhydroxylamines with KH. 1a and 1b [(KONMe2)(HONMe2)] dissolve in THF under the addition of an additional equiv of the parent hydroxylamine to give 1b and [(KONiPr2)(HONiPr2)(THF)] 2b. 1b, 2b and [(

Potassium is the most abundant exchangeable cation in the body. It exists predominantly in the intracellular fluid at concentrations of 140 to 150 meq/liter and in the extracellular fluid at concentrations of 3.5 to 5 meq/liter. The maintenance of the serum potassium concentration is a complex bodily function and results from the balance between intake,

Potassium supplements or potassium‐sparing agents
Acta Pharmacologica et Toxicologica, 1984Abstract:During diuretic treatment alterations in myocardial cellular excitability due to potassium‐induced dis‐turbances of the membrane potential may arise without obvious changes of total body K. This may be explained by coexisting disturbances of the acid/ base balance and other ions such as magnesium.

Potassium Citrate and Potassium Gluconate Versus Potassium Chloride
JAMA, 1967IN LATE 1964 a sudden increase in the occurrence of circumferential ulcerating, stenosing lesions of the small bowel was noted both in Europe and the United States. Lindholmer et al 1 in Sweden and Baker et al 2 in this country first suggested the association of these lesions with enteri-coated thiazide diuretic potassium chloride preparations ...
