Burn wound healing process consists of three phases of inflammation, proliferation and remodelling. The number of fibroblasts has increased during the proliferation phase. Oxidative stress in burn may disrupt proliferation through TGF-β inhibition, result in decreased number of fibroblasts and poor burn wound healing. Genistein in edamame seeds has anti-inflammatory, antibacterial and antioxidant properties. Edamame contains vitamins A, C, and E which is also have antioxidant properties. Edamame has been suggested to protect burn wound healing from oxidative stress. This study aimed to understand the effectiveness of edamame seed (Glycine max L. Merril) ethanolic extract (ED) to fibroblast count in second degree burn wound healing. This is true experimental research with post test only control group design. The sample of this research was 24 rat models of second degree burn which was made by attaching hot metal (60 ° C) for 5 seconds on the shaved back of the rats. The sample was divided into 6 groups with topical treatment, among others: positive control group (silver sulfadiazine), negative control group (Na CMC 0.5%), group with ED 20%, ED 40%, ED 60%, and ED 80%. Treatment was given for 15 days and skin sample was taken on the 16th day. Observation of the number of fibroblasts was done by taking pictures of histhologic preparations in Hematoxylin and Eosin staining under 400x magnification of light microscope. In one way ANOVA test, significance value of 0.011 (p≤0,05) indicated that there was at least a significant difference between 2 groups. LSD’s post hoc analysis showed that there was a significant difference in the group ED 20, 40, and 60% compared with negative control.

Burns is one of the popular accidents today and usually leaves serious physical and mental damage. For long time represent acute wounds, burns are evolution into chronic wounds, if inadequately managed. Up to now, there have been abundancy of natural and synthetic products for burn healing. In the study, we fabricated a thermosensitive nanocomposite hydrogel in which incorporated dual active curcumin and chitosan. Beside of a well-known characteristic of chitosan for wound healing, curcumin has been a lot of interest in burn wound healing application due to ability in depleting the action of oxidative radicals and stimulation of fibroblast cells. In order to enhance the therapeutic efficacy of curcumin, we introduced the new method to synthesize nanocurcumin in the a thermosensitive chitosan-g-Pluronic F127 copolymer solution under ultrasonication. The rheology of aqueous solutions of this material is studied as a function of temperature. The solutions of this material undergo a transition to a gel at higher temperature, above which a complex rheological behavior is observed. In addition, a minimum inhibitory concentration of this material was determined for a variety of bacterial and was compared to that of curcumin. It was found that the aqueous dispersion of this material was much more effective than curcumin against both positive and negative gram bacterial. In the third degree burn models, the nCur-CP hydrogel performed a higher burn healing rate as compared to Silvirin-treated burn. These data suggest that the nanocomposite hydrogel may be great potential for burn treatment.
