The results showed that the passively electrophysiological characteristics of SMC,such as the resting potential(RP),input resistance,could be recorded from the rat vas deferens.
采用细胞内微电极技术对大鼠离体输精管平滑肌细胞进行记录,观察其静息电位、膜阻抗等被动膜电性质及ACh对平滑肌细胞膜电位的作用,在此基础上运用微电泳技术对所记录细胞进行标记,从而分析不同走行方向的平滑肌细胞的电生理学特性。
The resting potential of amphibian cell can be affected by [ K+ ] in extracellular fluid it dropped while the [K+] rose.
细胞外液中钾离子浓度可影响细胞的静息电位,当细胞外液中钾离子浓度升高时,细胞的静息电位值将下降;细胞外液中钙离子浓度变化对骨骼肌的收缩性有影响,当细胞外液中钙离子浓度下降时,骨骼肌的收缩幅度将变小。
Resting potential of the Dorsophila 3rd instar larvae is -53± 5mV.
