From: Sodium selectivity of semicircular canal duct epithelial cells

   Na+-rich K+-rich

permeable Ussing chamber (Isc, μA/cm2) 6.16 ± 0.83 (9) 1.00 ± 0.34 (9)* 1.71 ± 0.26 (12) 1.17 ± 0.3 (12) ns
  Whole cell patch (I-120 mV, pA/pF) -60.8 ± 20.3 (9) -36.3 ± 17.3 (9)* -3.8 ± 0.1 (5) -3.6 ± 0.3 (5) ns

  1. Table entries are means ± SEM (number of experiments).
  2. Isc : short circuit current (μA/cm2), I-120 mV : whole-cell patch clamp current at -120 mV command voltage (pA/pF)
  3. Amilorde concentration was 100 μM for all experiments.
  4. Significant differences: *, P < 0.05; ns, not significant.
  5. Comparisons: Values in amiloride vs control (without amiloride) using the paired t-test.
