Partial Effect of Resveratrol on Wound Healing: Study on Wistar Albino Rats

Abstract

Purpose: There are multiple and specific phases during wound healing. Resveratrol (RSV) is a polyphenol compound found naturally in fruits. Resveratrol's antioxidant, anti-aging, cardioprotective, anti-inflammatory, and anti-carcinogenic effects have been shown. This study aims to determine the effects of RSV on perfusion, neovascularization, inflammation, and granulation stages of wound healing in addition to its antioxidant capacity over GPX and SOD.Methods: 16 female rats were divided into two groups as the RSV and control groups. Six excisions were made in each rat. Three excisions in each rat were sutured and the other 3 were left as open wounds. Topical RSV was applied to the wounds of the rats in the RSV group. No treatment was given to the control group. Blood perfusion of the wounds in both groups were measured using the PeriScan PIM 3 System Laser Doppler Blood Perfusion Imager. Punch biopsies were taken for histopathological examinations and for the evaluation of SOD, GPX, and MDA.Results: GPX level of the closed wounds belonging to the RSV group was higher compared to the control group. There was no statistically significant difference in SOD and MDA levels between the groups. Neovascularization was registered higher in the open wounds of RSV group. Conclusion: Within parameters, resveratrol has been shown to be effective in wound healing in various ways. The results of this study may shed light on new therapeutic approaches that can be used in the reversal of oxidative stress in wound-causing diseases.
