METHODS: Eighteen rats were randomly assigned into three equal groups; control, cecal punctuation and colon anastomosis and ozone theraphy. Sepsis was performed with a cecal punctuation in groups 2 and 3. The medical ozone theraphy was administered intraperitonealy for three weeks in group 3 while the other rats received saline injection. At the twenty second day serum were obtained for TNF-alpha and IL-1 beta, the colonic burst pressures were measured and colonic tissue samples were obtained for MDA and MPO levels. Histolopatological examination was evaluated with H&E stain, and Ki-67, IL-1 beta and the VEGF immunostaining densities were also compared. RESULTS: Intraperitoneal ozone administration reversed TNF-alpha, IL-1 beta, MDA and MPO levels and the colonic burst pressures. There was also a significant difference at immunostaining densities of histopathological examination. CONCLUSION: Medical ozone therapy may contribute to tissue healing by affecting the proliferation and the vascularization thus has benefits on colonic anastomosis at peritonitis in rats.eninfo:eu-repo/semantics/openAccessColonAnastomosis, SurgicalPeritonitisRatsArticle3121111182695962010.1590/S0102-8650201600200000052-s2.0-84960441340Q3WOS:000372808700005Q4
