AbstractBackground and Objectives: Sepsis and its related complications are associated with high morbidity and mortality, often leading to liver damage. Ozone, a molecule with anti-inflammatory and antioxidant properties, may offer protective effects. This study aimed to evaluate the therapeutic and protective impact of ozone on liver injury in a rat model of sepsis induced by cecal ligation and perforation (CLP). Material and Methods: A total of 36 rats were randomly divided into five groups: control (Group C), ozone (Group O), cecal ligation and perforation (Group CLP), ozone + cecal ligation and perforation (Group O+CLP), and cecal ligation and perforation + ozone (Group CLP+O). In the ozone groups, 4 mL of ozone (20 µ/mL) was injected intraperitoneally. Biochemical and histopathological parameters were evaluated in liver tissue samples obtained at the end of 24 h. Results: Polymorphonuclear leukocyte and monocyte infiltration and the total injury score were significantly reduced in the ozone-treated groups compared to the CLP group (p < 0.001). Tumor necrosis factor and interleukin 10 levels in the rat liver tissue were significantly reduced in the O+CLP and CLP+O groups compared to the CLP group, with the O+CLP group showing a more substantial decrease than the CLP+O group (p < 0.001). Thiobarbituric acid reactive substances and glutathione s-transferase levels were significantly lower in the ozone-treated groups compared to the CLP group (p < 0.001). Catalase activity was significantly elevated in the O+CLP group compared to the CLP group (p < 0.001). Serum aspartate transaminase, alanine transaminase, gamma-glutamyl transferase, and total bilirubin were significantly increased in the CLP group and decreased in the ozone-treated groups (p < 0.001, p < 0.001, p = 0.01, p < 0.001 respectively). Conclusions: Administering ozone to rats one hour before the CLP significantly mitigated liver damage, showing a more pronounced effect compared to administering ozone one hour after CLP. The results indicate that ozone could serve a protective function in managing sepsis-induced liver damage.
