Objective To investigate the effect of Fujiguning Ointment and epidermal growth factor (EGF) on the wounds with bone exposed. Methods Forty-five rabbits were made the models of a 2 cm×5 cm wound on theback with exposure of 4 spinl process and vertebral lamina of thoracic vertebrae, and divided into 3 groupsaccording to different methods of therapy: Group A(Fujiguning OintmentEGF), Group B(Fujiguning Ointment) and Group C(normal saline). During experimental period of 60 days, the healing of wounds was observed and immunohistochemistry and in situ hybridization were employed to detect the expression of EGF/EGFR and EGF/EGFRmRNA in the granulation tissues. From February 2002 to May 2003, 23 cases of wounds with bone exposure werelocally treated with Fujiguning Ointment and EGF. First, Fujiguning Ointmentwas used to cover the wounds. After the granulation grew and covered the exposed bone, EGF was used to infiltrate the wound until the wound healed. Results The healing time of wounds with bone exposure was shorterin group A(30 days) than those in group B (45 dyas) and group C (60 dyas), showing statistically significant difference (P lt;0.01). EGF/EGFR increased significantly, the expression of EGF and EGF mRNA reached the peak at the 15th day, the expression of EGFR and EGFR mRNA reached the peak during the 15th and the 22nd days in the Fujiguning OintmentEGF group and Fujiguning Ointment group in comparison with normal saline group. Twentythree cases of wounds were cured and the average healing time was 51 days. Conclusion Fujiguning Ointment and EGF can promote the healing of the wounds with bone exposure.
