Abstract

This study aims to evaluate the effects of topical sole and co-administration of Platelet-rich plasma (PRP) and chitosan on the infected burn wounds model by Candida albicans in Wistar rats. A circle partial thickness contact burn wound model occurred via brass a size of 8mm diameter between the shoulders and after that, 50μl of a suspension containing C. albicans yeast (5×107) colony forming unit was poured on the surface of the wound. The experimental groups included Control, Clotrimazole, PRP and Chitosan+PRP that received any agent, Clotrimazole®, PRP and Chitosan+PRP to treat the wound, respectively. To assess the healing rate, wound size rate, tissue yeast count (TYC) and immunohistochemical staining for heat shock protein 70 (HSP70), HSP 90 and proliferating cell nuclear antigen (PCNA) were conducted. Moreover, enzymatic activity of glutathione peroxidase (GPx), superoxide dismutase (SOD) and malondialdehyde (MDA) rate were evaluated. The results demonstrated that the co-administration of Chitosan+PRP drastically (P<0.05) decreased the wound size and TYC rate comparing to other groups (P<0.05). Immunohistochemical results for HSP 70, HSP 90 and PCNA showed positive reactions and increased intensity in all the treated groups comparing to the control group. Activities of GPx and SOD were higher and the level of MDA was lower all treated groups compared to the control group. A topical use of PRP and chitosan can be advantageous in the infected burn wounds healing. Copyright © 2020 Elsevier Ltd and ISBI. All rights reserved.
