Abstract
The radioprotective effect of lycopene against liver damage was investigated in 80 female Sprague Dawley rats (10 per group). Early-group rats included: controls (group 1), lycopene (group 2), radiotherapy alone (group 3), and lycopene + radiotherapy (group 4). Lycopene (5 mg/kg per day) was administered orally for 7 days; single-fraction 8 Gy abdominopelvic radiotherapy was administered on day 8. Early-group rats were sacrificed on day 10. Late-group rats (groups 5-8) underwent treatment with the same regimens but, in groups 6 and 8, lycopene was administered until all rats were sacrificed, 60 days postradiotherapy. Liver malondialdehyde levels increased significantly and glutathione (GSH) levels, GSH-peroxidase (GSH-Px) and superoxide dismutase (SOD) activity decreased significantly in radiotherapy versus control groups. In lycopene + radiotherapy groups, malondialdehyde levels decreased significantly and GSH levels, GSH-Px and SOD activity increased significantly compared with radiotherapy groups. No significant between-group histo pathological differences were observed in early groups; in late groups, histopathological changes increased significantly in the radiotherapy group versus control group. A significant decrease in histopathological changes occurred in the lycopene + radiotherapy group compared with the radiotherapy group. Lycopene supplementation significantly reduced radiotherapy-induced oxidative liver injury.
