Fig. 3. Effect of Korean Red Ginseng extract (KRG) on caspase-3. Cleaved caspase-3 was determined by Western blotting methods (A). Densitometric analysis of each protein was shown (B). Results are representative of three independent experiments. N/C, normal control; KRG control, isoproterenol (ISO) control, ISO injection only without KRG pretreatment; 250KRG+ISO, KRG pretreatment at the dose of 250 mg/kg for 7 d; 500KRG+ISO, KRG pretreatment at the dose of 500 mg/kg for 7 d. **p<0.01.
