【摘要】 本文用微电极细胞内电位记录、通道阻断剂和放射性同位素等技术发现,锌离子可诱发爆发波放电（BD）,钠通道阻断剂——河豚毒素对BD无效应,而钙通道阻断剂——Ca²⁺则可使BD消失,Cd²⁺可使[⁶⁵Zn²⁺];量减少。以上结果说明,Zn²⁺诱发BD的产生机理很可能是Zn²⁺代替Ca²⁺通过钙通道进入胞内引起的。更多还原

【Abstract】 The intracellular microelectrode recording technique, channel blocker and radioisotope tracer method were used. The burst discharges were evoked by Zn²⁺, no change by sodium channel blocker——Tetrodotoxin, but abolished by calcium channel blocker——Cd²⁺. [⁶⁵Zn²⁺]; was decreased by Cd²⁺. It is possible, that Zn²⁺, instead of Ca²⁺, goes into cells through calcium channels in the mechanism of BD evoked by Zn²⁺.更多还原
