A total of 24 male Sprague Dawley rats were divided into three groups: sham-operated, PH and PH+UD; each group contains eight animals. The rats in UD-treated groups were given UD oils (2ml/kg/day) once a day orally for 7days starting 3days prior to hepatectomy operation. At day 7 after resection, liver samples were collected. The levels of malondialdehyde (MDA), superoxide dismutase (SOD) and glutathione (GSH) were estimated in liver homogenates. Moreover, histopathological examination, mitotic index (MI), proliferating cell nuclear antigen labeling, proliferation index (PI), transferase-mediated deoxyuridine triphosphate nick end-labeling assay, apoptotic index (AI) were evaluated at day 7 after hepatectomy. As a result, UD significantly increased MI and PI, significantly decreased AI and also attenuated hepatic vacuolar degeneration and sinusoidal congestion in PH rats. UD treatment significantly decreased the elevated tissue MDA level and increased the reduced SOD activity and GSH level in the tissues. These results suggest that UD pretreatment was beneficial for rat liver regeneration after partial hepatectomy.en10.1177/0748233713480211info:eu-repo/semantics/closedAccessUDPartial HepatectomyOxidative StressImmunohistochemistryTUNELRatCell Nuclear AntigenLiver-RegenerationLipid-PeroxidationHepatocellular-CarcinomaSuperoxide-DismutaseGrowth-FactorVitamin-EAntioxidantHepatocytePathologyArticle315475484Q2WOS:0003540228000122-s2.0-8493045317123456814Q3
