Figure 5: Contents of VEGF, TGF-β, and PDGF in tissue specimens (pg/mg). Before treatment there were no significant differences in the contents of VEGF, TGF-β, and PDGF in the wound between the ozone group and the control group ( versus , ; versus , ; versus 15.50 + 0.78, ). But after treatment the contents of VEGF, TGF-β, and PDGF were all significantly higher in the ozone group than in the control group ( versus , ; versus , ; versus , ). , .
