This work was planned to research the effects of lipopolysaccharide (LPS) and/or vitamin E (VE) and sodium selenite (SS), which have antioxidant properties, administered to the liver tissue of male rats. For this purpose, histopathology, immunohistochemistry, antioxidant capacity, terminal deoxynucleotidyl transferase (TdT) dUTP nick-end labeling assay, liver function, and DNA structure tests were performed. The lipid profile was also evaluated in this study. Rats that were administered LPS were treated with VE and/or SS. The liver function tests and lipid profile parameters showed statistically significant changes and histological alterations in the LPS treated groups. The number of cells entering apoptosis was increased by LPS administration when compared to the control group. LPS treatment increased the DNA damage and decreased the ferric reducing antioxidant power and trolox equivalent antioxidant capacity values when compared to the control group. VE and/or SS provided protective effects against the examined parameters. These results indicated that we can assume that the treatment of VE and SS together may be more efficient than using them individually against LPS.

This work has been prepared to find out changes in the biochemicals with DNA damage, micronucleus, and apoptosis to lipopolysaccharides (LPS) alone or vitamin E (VE) and sodium selenite (SS) in rats’ blood tissue. Rats were divided into eight groups according to the treatment into control vitamin E (VE) treatment group (200 mg/kg bw), sodium selenite (SS) treatment (0.35 mg/kg bw) group, VE + SS treatment group (200 + 0.35 mg/kg bw), LPS treatment group (10 mg/kg bw), LPS + VE (10 + 200 mg/kg bw), LPS + SS treatment (10 + 0.35 mg/kg bw), and LPS + SS+VE treatment (10 + 0.35 + 200 mg/kg bw) group for 6 hr. LPS increased malondialdehyde (MDA) level and decreased antioxidant enzymes’ activities in rat erythrocytes and leukocytes. DNA damage of leukocytes with comet assay and RAPD‐PCR was detected in LPS treatment group. The levels of micronucleus and apoptosis percentage were increased significantly at the end of 6 hr. VE and/or SS protected the LPS‐induced erythrocytes and leukocytes against damage as they have caused amelioration of rats by altering the results. As a result, the co‐administration of VE and/or SS against LPS‐induced damage provides protection. VE and/or SS in patients and animal models with sepsis must be taken in the diet because they are protective against the cellular degradation caused by oxidative damage. Practical applications LPS obtained from E. coli is used more frequently in experimental sepsis studies. When LPS is administered to experimental animals, interstitial pneumonia, adult respiratory fatal syndrome, acute tubular necrosis, and fatal effects such as coagulopathy and hypoglycemia may be seen in these animals. The co‐treatment of VE and SS may be more effective than using them alone against LPS.
