Unlabelled:
This study examined a combination of artificial dermis and basic fibroblast growth factor (bFGF) to treat skin defects in clinical cases, and it histopathologically examined the effects on the conditions of recipient beds.
Materials And Methods:
The subjects were 11 patients with skin defects from burn ulcers or traumatic ulcers. In each subject, debridement was performed and subsequently artificial dermis was applied to the defect. The bFGF was used on 1 side (combination therapy) of the artificial dermis and not used on the other side (artificial dermis monotherapy). A histopathological examination was performed on the granulation tissue collected from the recipient bed. The authors also measured skin hardness 6 months after the skin graft.
Results:
Histologically, the combination therapy site had more extensive capillary angiogenesis than the monotherapy site. The combination therapy site also had capillary walls consisting of thick, large endothelial cells; fibroblast proliferation and activation; and more severe infiltration of inflammatory cells. Skin hardness after the graft was also much softer in the combination therapy.
Conclusion:
The results suggest the usefulness of this combination therapy in the preparation of skin graft beds to improve skin hardness after skin grafts in clinical cases.
