Gastrointestinal symptoms (discomfort, mucosal lesions and sometimes ulceration) have been seen in healthy subjects taking some forms of potassium supplements (e.g. slow-release, wax matrix formulations) with doses ranging from about 1 to 5 g potassium per day, or more, but incidence and severity seem to be more dependent on the formulation than on dose. In healthy adults administration of sing...

This communication is concerned with the formation of spheroidal bodies from Bacillus megaterium strain KM, by the action of potassium tellurite in a hypertonic sucrose medium. Cells grown in sucrose-casein hydrolyzate broth (Lederberg and St. Clair, J. Bacteriol., 75, 143, 1958) were inoculated into fresh broth and aerated at 37 C for 3 to 4 hr. Potassium tellurite (final concentration 0.05 pe...

Low potassium and magnesium status and decreased Na, K-pump activity is an endemic condition among rural Northeast Thais. The authors examined the effect of supplementing potassium and magnesium on erythrocyte potassium, sodium and magnesium content and on Na, K-pump activity. Rural Northeast Thai renal stone patients (62) were recruited, divided into four groups and supplemented for one month ...

Canonical correlation analysis was applied to the study of interrelationships between two multivariate datasets, one consisting of available and exchangeable potassium content, and second consisting of pH, hydrolytic acidity, and content of exchangeable aluminum, calcium and magnesium, available phosphorus, and total nitrogen. An attempt has been made to provide an overall pattern of interrelat...

Aim: Many countries import potassic fertilizers due to dearth of K-mineral deposits. Therefore processes to obtain K-nutrient sources from sea bittern were developed by our Institute. The present investigation evaluated the fertilizer potential of three different sea bittern-derived (SBD) potassium forms developed viz., potassium schoenite, potassium nitrate and potassium ammonium sulfate on ma...

The concentrations of Cs and potassium in the surface layers of arable soils were analyzed in the selected region of Eastern Poland approximately 20 years after the Chernobyl power plant accident. Additionally, the occurrence of the elements in soil in the forms available for plants was determined. In relation to the total concentrations of Cs and K in the soil, cesium is found in larger quanti...
