摘要 目的和方法:采用全细胞式膜片钳技术,观察花生四烯酸(AA)对大鼠顶叶皮层神经元延迟整流钾电流(Ik)的影响。结果:①AA(10μmol/L)对大鼠顶叶皮层神经元Ik有抑制作用,抑制率为33.9%±8.74%(P<0.01)。②AA可使IK激活曲线的斜率因子变大且曲线向右移动,IK激活曲线的V1/2和k分别由给药前的(-55.3±0.9)mV和(10.3±0.4)mV,变为给药后的(-50.8±2.4)mV和(21.0±3.5)mV。③AA可使IK失活曲线斜率因子变大且曲线向左移动,IK失活曲线的V1/2和k分别由给药前的(-45.3±0.3)mV和(15.6±0.8)mV,变为给药后的(-70.9±1.9)mV和(36.5±2.1)mV。结论:花生四烯酸可抑制大鼠顶叶皮层神经元的延迟整流钾电流,并影响其动力学特征。
