Noradrenaline release from the rat heart during anoxia: effects of changes in extracellular sodium concentration and inhibition of sodium uptake mechanisms.

abstract：:1. Na+/H+ exchange, an ethylisopropylamiloride (EIPA)-sensitive Na+ and HCO3- dependent system and a diisothio-cyanatostilbenedisulphonic acid (DIDS)-sensitive Na+ and HCO3- transporter, contribute to sodium influx and intracellular pH (pHi) regulation in vascular smooth muscle. 2. In cultured cells from the human int...
