In a Ca-free, Mg-free medium containing EGTA (10-3M) auricular trabecles develop a slow inward current which is a pure sodium current. After 12 min in this medium, it is still possible to obtain a phasic mechanical activity which shows a perfect correlation with the current. This kind of behavior indicates that a mechanism of sodium-induced calcium release is present at the level of some internal sites.
在含有乙二醇双(2-氨基乙基醚)四乙酸(10⁻³M)的无钙、无镁培养基中,心耳小梁产生一种缓慢的内向电流,这是一种纯钠电流。在这种培养基中培养12分钟后,仍然有可能获得与电流呈现完美相关性的阶段性机械活动。这种行为表明,在一些内部位点存在钠诱导钙释放的机制。
