[Retracted] Effects of Early Weight-Bearing Treadmill Training Combined with Pre-Emptive Analgesia on Femoral Fracture Recovery

Figure 5

IHC staining results of VEGF. (a) Representative images of bone tissue around the fracture site from four groups at 7 d after surgery by IHC staining of VEGF (scale bars, 50 μm). White arrows indicate positive cells with brown stain. (b) Representative images of bone tissue around the fracture site from four groups at 14 d after surgery by IHC staining of VEGF (scale bars, 50 μm). White arrows indicate positive cells with brown stain. (c) Representative images of bone tissue around the fracture site from four groups at 21 d after surgery by HE staining of VEGF (scale bars, 50 μm). White arrows indicate positive cells with brown stain. (d) Representative images of bone tissue around the fracture site from four groups at 28 d after surgery by HE staining of VEGF (scale bars, 50 μm). White arrows indicate positive cells with brown stain. (e) Representative images of bone tissue around the fracture site from four groups at 35 d after surgery by HE staining of VEGF (scale bars, 50 μm). White arrows indicate positive cells with brown stain. (f) Immunohistochemical score of VEGF for each group at every time points (n = 3). For quantification of each sample, 3 optic fields were chosen randomly. vs. group B; vs. group B; ^# vs. group C; ^## vs. group C.
