Aim: Liver is mostly exposed to radiation during radiotherapy to the upper abdomen, the right lobe of the lung, distal esophagus tumors or total body irradiation. Radiation may lead to cellular damage, and clinical and laboratory findings of liver dysfunction. This study aimed to investigate the protective effect of peroral hesperidin on reducing oxidative stress in liver tissue caused by ionızing radiation Material and Methods: 24 adult male rats were randomly divide into four groups. Group control was given only physiological saline, Group HES was given hesperidin at 50 mg/kg body weight (BW) for 15 days, Group RAD was given only irradiation, and Group HES+RAD was given hesperidin at 50 mg/kg BW daily and then irradiated. At the end of 15 hesperidinin days, the animals in Groups RAD and HES+RAD were exposed to a dose of 10 Gy to the abdominopelvic region. Liver and blood samples were used for determination of total antioxidant status (TAS) and malondialdehyde (MDA) and also histopathological examination was performed.Results: Compared with the Group RAD, the plasma and tissue MAD level was significantly decreased in Group HES+RAD (p=0.002). Both plasma and tissue levels of TAS was found significantly higher in HES+RAD group (respectively, p=0.002,p=0.004). Histological examination of Group RAD, portal edema, significant intra-cytoplasmic vacuolization, swelling in the hepatocytes, necrosis, significant sinusoidal and central vein dilation and congestion were observed . In group HES+RAD periportal edema, central vein dilation and congestion were not histologically evident when compared with Group RAD. Conclusion: Radiotherapy was found to lead to an increase in lipid peroxidation and a reduction in anti-oxidant capacity; 50 mg/kg/day hesperidin administration for 15 consecutive days was seen to reduce the histological changes of liver damage and oxidative stress in rats
