General view of the postoperative wound and evaluation of the effect of epidermal growth factor (EGF) combined with vacuum sealing drainage (VSD) in the treatment of wounds. a. General views of the postoperative wound and the wound 10 d after the operation. b. The filling rate of granulation tissue in the wound area 10 d after the operation (Control: 0.22 ± 0.02, VSD: 0.31 ± 0.04, V + E 10 min: 0.42 ± 0.03, V + E 30 min: 0.44 ± 0.03). c. The contractibility rate of the wound area 10 d after the operation (Control: 0.14 ± 0.01, VSD: 0.13 ± 0.03, V + E 10 min: 0.10 ± 0.02, V + E 30 min: 0.11 ± 0.02). d. The hydroxyproline content in the wound area 10 d after the operation (Control: 0.67 ± 0.05 μg/mg*prot, VSD: 0.93 ± 0.18 μg/mg*prot, V + E 10 min: 1.58 ± 0.16 μg/mg*prot, V + E 30 min: 1.64 ± 0.10 μg/mg*prot). Data are shown as means ± SD, **P < 0.01
