Objective. We aimed to investigate the protective and therapeutic effects of dexpanthenol (DXP) on liver injuries induced by ischemia-reperfusion (IR) in an in vivo rat model.
Methods. Thirty-two rats were randomly divided into 4 experimental groups (n = 8 in each group: Sham, IR, DXP, and DXP+IR. DXP (500 mg/kg) was intraperitoneally administered for 30 min before 60 min of ischemia, followed by 60 min of reperfusion to rats in the DXP and DXP+IR groups. All rats were euthanized on day 10 to evaluate immunohistopathological changes as well as tissue levels of oxidants and antioxidants.
Results. IR decreased total glutathione (tGSH) levels in IR group when compared to the Sham group. DXP supplementation to IR group significantly ameliorated tGSH levels (P < .05). IR also elevated myeloperoxidase production compared to the Sham group, whereas DXP treatment prevented these hazardous effects. However, plasma superoxidedismutase, catalase, and malondialdehyde levels did not differ between the DXP+IR than the IR rats. Histologic tissue damage was reduced in the DXP and DXP+IR group.
Conclusion. Liver IR is an inevitable problem during liver surgery. Our results suggested that DXP pretreatment suppressed oxidative stress and increased antioxidant levels in a rat model of liver IR.
