Effects of ginsenoside Rb1 on burn wound healing. a–e Expressions of PDGF-BB, PDGFR-β, and FGF-2 on days 0, 7, 14, and 24 after burn injury. The protein expression levels of PDGF-BB, PDGFR-β, and FGF-2 were normalized to those of β-actin and quantified with ImageJ v1.49 software. The data are expressed as the means ± SDs. *P < 0.05, ** P < 0.01, and *** P < 0.001 vs. the control group; ^#P < 0.05 and ^##P < 0.01 vs. the MD group. n = 6 rats per group. βactin was used as the internal reference. 1 Control group, 2 MD group, 3 Low-dose ginsenoside Rb1 group (1.25 g/kg), 4 Medium-dose ginsenoside Rb1 group (2.5 g/kg), 5 High-dose ginsenoside Rb1 group (5 g/kg), 6 Positive control group (1% SSD)
