Effects of Aloe Vera and Chitosan Nanoparticle Thin-Film Membranes on Wound Healing in Full Thickness Infected Wounds with Methicillin Resistant Staphylococcus Aureus
Journal Title: Bulletin of Emergency And Trauma - Year 2018, Vol 6, Issue 1
Abstract
Objective : To assess effect of Aleo vera with chitosan nanoparticle biofilm on wound healing in full thickness infected wounds with antibiotic resistant gram positive bacteria. Method: Thirty rats were randomized into five groups of six rats each. Group I: Animals with uninfected wounds treated with 0.9% saline solution. Group II: Animals with infected wounds treated with saline. Group III: Animals with infected wounds were dressed with chitosan nanoparticle thin-film membranes. Group IV: Animals with infected wounds were treated topically with Aloe vera and Group V: Animals with infected wounds were treated topically with Aloe vera and dressed with chitosan nanoparticle thin-film membranes. Wound size was measured on 6, 9, 12, 15, 18 and 21days after surgery. Results: Microbiology, reduction in wound area and hydroxyproline contents indicated that there was significant difference (p<0.05) between group V and other groups. Quantitative histological studies and mean rank of the qualitative studies demonstrated that there was significant difference (p<0.05) between group V and other groups. Conclusion: The Aloe vera with chitosan nanoparticle thin-film membranes had a reproducible wound healing potential and hereby justified its use in practice.
