From: Chemical characterization of wound ointment (WO) and its effects on fracture repair: a rabbit model
WO accelerated fracture healing by promoting the release of VEGF. Immunohistochemistry of positive signal of vascular endothelial growth factor (VEGF) within the fracture end at each time point (3, 7, 14, 21, 28 and 35 days) in the control group, Yunnan Baiyao (YB) group and Wound Ointment (WO) group. **P < 0.01, YB group versus control group; ## P < 0.01, WO group versus control group
