(A) Typical experiment showing the effect of ginsenoside Rb₁ and Re on myocyte shortening in ventricular myocyte isolated from adult male rat hearts. Myocyte shortening and relengthening were recorded at 25°C before and 10 min after ginsenoside Rb₁ and Re (100 nM) administration. (B) Concentration-dependent response to ginsenoside Rb₁ and Re (1 – 1000 nM) on myocyte shortening. The basal PS is 5.22±0.58 and 5.26±0.71% of the cell length in Rb₁ and Re group, respectively. Mean±s.e.mean, n=25 – 27/data group. ^*P<0.05 vs baseline value.
