CEAA blocks VDCC currents on ASMCs. (a) The ASMC membrane under voltage clamp was stepped up from a holding potential of −70 mV to test-pulse potentials ranging in 10 mV steps from −60 mV to +40 mV. (b) VDCC currents were recorded following the depolarization steps as described in (a), and they were blocked by CEAA or nifedipine. (c) I-V relations were plotted based on the results of 7 experiments.
