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.
