T he Na,K-ATPase (or Na pump) is an integral membrane protein that transports Na and K across the plasma membrane of almost all animal cells and couples this work to the hydrolysis of the terminal phosphate bond of ATP (1). A significant fraction (up to 30%) of the ATP generated by cell metabolism is dedicated to this active transport process. The electrical gradient created by the Na pump is e...
The effect of thyroxine on membrane bound (Na+, K+)-ATPase isolated as a microsomal fraction from rabbit heart and kidney was investigated. In the heart, thyroxine administration produced an increased Ki value (a concentration of ouabain required for half maximal inhibition of (Na+, K+)-ATPase activity) without alteration of the specific activity of cardiac (Na+, K+)-ATPase, indicating that the...
Stevia rebaudiana Bertoni is a shrub having a high content of sweet diterpenoid glycosides in its leaves, mainly stevioside and rebaudioside A, which are used as noncaloric, natural sweeteners. The aim of this study was to deepen the knowledge about the insulin-mimetic effect exerted by four different mixtures of steviol glycosides, rich in stevioside and rebaudioside A, in neonatal rat cardiac...
Cardiac glycosides are widely available in botanic products and other naturally occurring substances worldwide. Accidental consumption of it leads to digitalis toxicity with varied systemic manifestations. We describe a case of consumption of extract of leaves of the Indian rubber vine plant (Crytostegia grandiflora) which led to gastrointestinal, cardiac, electrolyte, and hematological disturb...
