Fig. 6.
Effect of ginsenoside Rd (GSRd) on ICa,L of myocyte pretreated with pertussis toxin, ISO, and forskolin. The left panels in this and the following figures represent peak amplitude of ICa,L in a representative myocyte against the time. The timing of the drug applications is shown on the top. The right panel depicts superimposed current traces recorded at the timing indicated by lower-case letters in the left panel. (A) Effects of GSRd (30 μmol/L) on ICa,L. (B) Effects of GSRd (30 μmol/L) on ICa,L of myocyte pretreated with pertussis toxin. (C) Effects of GSRd (30 μmol/L) on ICa,L that had been stimulated by ISO (1μmol/L). (D) Effects of GSRd (30 μmol/L) on ICa,L stimulated by forskolin (10 μmol/L).
