Myocardial mechanical responses and ionic exchange in high-sodium perfusate.

The effects of an extracellular sodium (Na) concentration of 200 mM on function, ionic exchange, and water movements were examined in the vascularly perfused rabbit intraventricular septum. When the perfusate was switched from 142 mMNa to 200 mMNa, dP/ dt fell 20.4% over 2 minutes; dP/dt then recovered to the control level. The time course of the functional recovery correlated with the uptake o...

Effects of digitalis on myocardial ionic exchange.

SUMMARY Prior to consideration of the effects of digitalis compounds on ionic exchange the basic mechanisms of active Na+ and K+ transport are discussed. It is generally accepted that digitalis is a specific inhibitor of the Na+-K+ activated ATPase located primarily in the sarcolemmal membrane. Present evidence supports the concept that positive inotropic effects of digitalis are not seen unles...

The responses of L-gulonolactone oxidase and HKT2;1 genes in Aeluropus littoralis’ shoots under high concentration of sodium chloride

Salinity is one of the most important abiotic stresses that limit crop growth and production. Salt stress influences plants in two ways: by affecting ion toxicity and increasing osmotic stress. Ion homeostasis, the excretion of Na+ and using antioxidant systems are the major strategies of salt tolerance in plants. Na+ and K+ transporters with enzymes that are involved in detoxification of react...
