关于阳离子在心脏电生理学的离子机制已有广泛报道。然而,最近日本Kyushu大学的两位学者T.Ehara和K.Ishhihara证明,心脏中的Cl~-通道可被肾上腺素激活,阴离子通道在交感活动控制中扮演一个特殊的角色。他们用电压钳技术记录到心肌细胞有一种外向的Cl~-通道整流电流。与心肌细胞中其它的儿茶酚胺依 There have been widely reported ionic mechanisms of cations in cardiac electrophysiology. However, recently, two scholars at Japan’s Kyushu University, T. Ehara and K.Ishhihara, have shown that the Cl ~ -channel in the heart can be activated by adrenaline, and that the anion channel plays a special role in the control of sympathetic activity. They used voltage-clamp techniques to record that there is an outward-going Cl ~ -channel rectifier current in cardiomyocytes. With other catecholamines in cardiomyocytes
