Effect of ginseno side Rb₁ and Re on intracellular Ca²⁺ transient changes (Δ[Ca²⁺]_i) in ventricular myocytes. Top panel: typical experiment showing the effect of ginsenoside Rb₁ and Re (100 nM) on intracellular Ca²⁺ transients. Solid and dashed traces show Ca²⁺ transients recorded from a fura-2 loaded myocyte before and 10 min after ginsenoside Rb₁ and Re exposure; Lower panel: concentration-dependent response of ginsenoside Rb₁ and Re (1 – 1000 nM) on intracellular Ca²⁺ transient changes (ΔFFI) in ventricular myocytes. Δ[Ca²⁺]_i is expressed as the per cent change of respective baseline value. Mean±s.e.mean, n=17 – 18/data group, ^*P<0.05 vs baseline value.
