Skin damages are usual physical injuries and different studies have been done to improve wound healing. Hydrogel dueto its properties like a moist environment and cooling wound site is a good option for wound treatment. In this study, weevaluated the consequence of using alginate/chitosan hydrogel contained various dosages of 4-Methylcatechol (0, 0.1, 1%(W/W)) on wound healing. After hydrogel fabrication, different tests like SEM, swelling, release, weight loss, and hemoandcytocompatibility were done to characterize fabricated hydrogels. Finally, the rat model was used to assess Alginate/Chitosan hydrogel's therapeutic function containing 0.1 and 1% of 4-Methylcatechol. The pore size of hydrogel was between24.5 ± 9 and 62.1 ± 11.63 μm and about 90% of hydrogel was lost after 14 days in the weight loss test. Blood compatibilityand MTT assay showed that hydrogels were nontoxic and improved cell proliferation. In vivo test showed that Alginate/Chitosan/0.1%4-Methylcatechol improved wound healing and the results were significantly better than the gauze-treatedwound. Our results showed dose depending effect of 4-Methylcatechol on wound healing. This study shows the treatmenteffect of 4-Methylcatechol on wound healing and the possibility of using it for treating skin injuries.

In this study, cinnamon (cin) was loaded into poly(ε-caprolactone)/gelatin (PCL/Gel) nanofi brous matrices in order to fabricatean appropriate mat to improve wound healing. Mats were fabricated from PCL/COLL [1:1 (w/w)] solution with 1, 5and 25% (w/v) of cinnamon. Prepared mats were characterized with regard to their microstructure, mechanical properties,porosity, surface wettability, water-uptake capacity, water vapor permeability, blood compatibility, microbial penetration andcellular response. The fabricated mats with and without cinnamon were used to treat the full-thickness excisional wounds inWistar rats. The results indicated that the amount of cinnamon had a direct eff ect on porosity, mechanical properties, wateruptake capacity, water contact angle, water vapor transmission rate and cell proliferation. In addition, the results of in vivostudy indicated that after 14 days, the wounds which were treated with PCL/Gel 5%cin had better wound closure (98%)among other groups. Our results suggest that the cinnamon can be used as a suitable material for wound healing.
