Figure 2. Myeloperoxidase mRNA in human skeletal muscle 24 h after squat exercise. Myeloperoxidase mRNA (neutrophil marker) decreased post exercise when immunostimulant Rg1 was supplemented 1 h before exercise (A). Myeloperoxidase mRNA is highly correlated with p16INK4a mRNA (B) In muscle tissues. **denotes significant difference against Pre, p < 0.01. Abbreviations: Pre: before exercise; Post: 24 h after exercise. MPO: Myeloperoxidase; PLA: Placebo; Rg1: Ginsenoside Rg1.
