Figure 3: Time-dependent effects of Rg3 on the secretion of CA produced by high K+ (left) and Bay-K-8644 (right) in the isolated adrenal medulla of the rat. The release of CA evoked by an injection of K+ (56 mM) with a volume of 100 μL and infusion of Bay-K-8644 (100 μM) for 4 min was produced at 15-min intervals during perfusion of Rg3 (10 μM) for 1.5 h as designated by the bolt marks. The collection of perfusates produced by high K+ or Bay-K-8644 was performed for 4 min. Other legends are identical to those of Figure 1. **P < 0.01. Rg3: Ginsenoside-Rg3; ns: Statistically nonsignificant; CA: Catecholamines
