1·Neither sodium valproate nor Verapamil showed any effect on action potential amplitude, overshoot, resting potential and phase o upstroke velocity.

丙戊酸钠和异搏定对动作电位幅度、超射值、静息电位、O期最大除极速度均无明显影响。

2·Cells in the secretory portion and duct have different electrophysiological phenomena. At normal condition, resting membrane potential of secretory cells was obviously higher than that of duct cells.

汗腺导管细胞和分泌细胞具有不同的电生理现象，正常状态下分泌细胞静息膜电位明显高于导管细胞。

3·GIRK channels are involved in the regulation of the excitability of neurons and cardiac rate. They may contribute to the resting and inhibitory postsynaptic potential.

它能调节心率及神经细胞兴奋性和静息电位的水平，起慢突触后抑制作用。
