Background: rhGM-CSF has been shown to enhance the migration and proliferation of endothelial cells and to promote keratinocyte growth. This study was tried to evaluate the effect of rhGM-CSF dressing on the uninfected wounds. Methods: Thirty Sprague-dawley white mice(250-300g) were selected in this study. The number of wound with the diameter of 5 mm, was 3 in left and 3 in right at the symmetric sites, respectively. The site of rhGM-CSF dressing was decided by a randomization. rhGM-CSF($Leucogen^{(R)}$) was diluted in the distilled water($5{\mu}g/mL$). The experimental wound group was dressed by l mL of distilled water mixed with rhGM-CSF and control wound group was dressed by l mL of distilled water. The dressing was done, every 24 hours. The criteria of comparison were the duration of wound healing duration, histologic findings and the bacterial culture of wound sites. Results: The duration of wound healing was $10.3{\pm}1.7days$ in experimental group and $10.2{\pm}2.8days$ in control group, without significant difference. There was no specific difference of histologic findings between both groups. The pathogen was not found, at all. Conclusion: It seems to be that rhGM-CSF has no prominent effect on the uninfected wound healing in the mice without immune suppression.

The authors have treated a squamous-cell carcinoma occurred in molar region of the right mandible in 52-year old woman by means of bony resection and banked tibial bone graft, and made the normal appearance of her face. The result as follow: 1) The healing of a graft is similar to the healing of an uninfected fracture except that it will take considerably longer. It is of the utmost importance that it should be well immobilized, otherwsie there is danger of absorption of bone and fibrous union. 2) Until the graft acquires a blood supply it is easily infected, for it has no defence against organisms, so it is most important to prevent wound infection set in.
