Group I: Animals with created wounds and no further treatment. Group II: Animals with wounds were dressed with chitosan film only. Group III: Animals with wounds were treated with sodium selenite. Group IV: Animals with wounds were treated with sodium selenium nanoparticles. Group V: Animals with wounds were dressed with chitosan/ sodium selenite film. Group VI: Animals with wounds were dressed with chitosan/nano selenium film.Results- There were significant differences in comparisons of group VI and other groups, particularly in terms of cellular infiltration and neovascularization. During the study period, scores for neovascularization was significantly higher in group VI rats than other groups (P <0.05). Polymorphonuclear (PMN) and mononuclear (MNC) cell count and fibroblast cell proliferation in group VI were significantly higher than those of other experimental groups (P <0.05)Conclusion and Clinical Relevance- Chitosan/nano selenium biodegradable film resulted in significant improvement in histopathological indices in full-thickness wound healing. Thus, from this study it could be concluded that chitosan/nano selenium biodegradable film have a reproducible wound healing potential and hereby justifies its use in practice. %U https://www.ivsajournals.com/article_66082_25797b6a202c661d0e0034ad869026f8.pdf
