Fig. 2. Effect of OA on density–voltage and conductance–voltage relationships. (A) Current density–voltage relationships were plotted for the L-type inward current of sea bass ventricular myocytes in controls (black crosses; N=11 between –60 to +30) and in the presence of 30 µmol l^–1 OA (red diamonds; N=9 between –60 to +30). For +40 mV N=9 and N=7 in control and OA conditions, respectively. (B) Conductance curves constructed from the density–voltage curves in A. Values are mean ± s.e.m. Significant differences between control and the different OA concentrations are indicated (*P<0.05, **P<0.01).
