Abstract
The Ca ionophores markedly enhance the increase of intracellular Ca occurring during Na-free perfusion and the hyperpolarization observed upon Na readmission may be due to rapid restoration of intracellular Na and resultant stimulation of both electrogenic sodium and calcium efflux.
摘要
钙离子载体显著增强了无钠灌注期间细胞内钙离子的增加，而重新引入钠时观察到的超极化可能是由于细胞内钠的快速恢复以及由此产生的电生性钠和钙外流的刺激。
