Disease relevance of potassium

• A similar insignificant difference was recorded between the indirect determination of Ke and its direct measurement by potassium-42 dilution in 15 normal dogs, five dogs with uremia, 14 dogs in an hyposmolar state, and in 20 patients [1].

High impact information on potassium

• Creatine kinase release, potassium-42 content, and mechanical performance in anoxic rabbit myocardium [2].
• Acetylcholine and potassium-42 movements in right atrial muscle of the guinea pig [3].
• A23187 also increased the potassium-42 exchange in the isolated epithelium [4].
• Measurements were made before and after the lithium treatment of total body water (tritium space), extracellular fluid (sulphate space), total exchangeable sodium (Nae) and total exchangeable potassium (Ke) using sodium-24 and potassium-42 multiple isotope dilution techniques [5].

Analytical, diagnostic and therapeutic context of potassium

• The relative specific activity of different tissues in adult male chickens determined at different time intervals after the intravenous injection of potassium-42 indicated that the plasma pool potassium had the highest turnover rate of potassium in the body [6].
