从豚鼠耳蜗顶端匝部分离出外毛细胞。在含钾量为5.8、14.0、28.9和67.5 mmol/l的细胞外培养基中，细胞的膜电位差分别为-72.0 +/- 0.6（平均+/- SEM， n = 93）、-50.1 +/- 2.1 （n = 4）、-37.7 +/- 0.5 （n = 73）和-20.0 +/- 1.5 mV （n = 16）。膜去极化可以解释三分之二的K（+）诱导的离体外毛细胞缩短。
Outer hair cells were isolated from apical turns of the guinea pig cochlea. The membrane potential differences of cells in extracellular medium with 5.8, 14.0, 28.9 or 67.5 mmol/l of potassium were -72.0 +/- 0.6 (mean +/- SEM, n = 93), -50.1 +/- 2.1 (n = 4), -37.7 +/- 0.5 (n = 73) or -20.0 +/- 1.5 mV (n = 16), respectively. Membrane depolarization can explain two thirds of the K(+)-induced shortening of isolated outer hair cells.
