Figure 4. Calcium and iberiotoxin sensitivity of Iout.

Figure 4

Currents were evoked in non-pregnant (NPM) and pregnant (PM) rat uterine myocytes by applying 200 ms depolarizing pulses from a holding potential of -60 to +80 mV. Original current recordings from a NPM (A) and a PM (C) cell exposed to 1 μM A23187 first and then additionally to 100 nM iberiotoxin (IbTX) are shown. B and D, summary of the effects of A23187 and of A23187 plus IbTX on Iout of five NPM and PM cells, obtained from five and four rats, respectively. Bars represent mean current densities. *P < 0.05; **P < 0.01; ***P < 0.001 versus control.
