Abstract

PURPOSE
Cellulose is a natural substance from plants or bacteria. It is known that bacterial synthesized cellulose has an effect of wound healing. The aim of this study is to show the effect of bacterial synthesized cellulose from citrus on wound healing.
METHODS
Three full-thickness skin defects were made on the back of Sprague-Dawley rats. Three wounds were treated by vaseline gauze(Group V), Algisite M(R)(Group A) and bacterial synthesized cellulose from citrus(Group C) was used for dressing on skin defect on rats. We analyzed the gross, histological and biochemistry finding.
RESULTS
Group C showed more decrease of wound size compared to Group V(33% versus 7.2#) after 14 days. The histologic findings revealed Group C and Group A preceed the process of wound healing rather than Group V(More rapid collagen deposition and neovascularization and reduced inflammation). Also, the expressions of vascular endothelial growth factor(VEGF) and transforming growth factor(TGF)-beta1 were increased in the Group C and Group A compared with the Group V in 7 days. VEGF and TGF-beta1 expression were decreased in the Group C and Group A in 14 days, however Group V was not decreased at 14 day because of delayed wound healing process.
CONCLUSION
Bacterial synthesized cellulose from citrus affects wound healing by reducing the inflammatory stage. And stimulates wound contracture by the deposition of extracellular matrix, thus preventing the formation of chronic wounds.
