Objective  To study the effects of edaravone on the lung injury of severe acute pancreatitis (SAP) in rats. Methods  Thirty-six SD rats were randomly divided into three groups: normal control group, model group and edaravone group, and SAP was induced by intraductal administration of 5% sodium taurocholate. Edaravone was given in edaravone group, while normal saline was given in normal control group and model group. After operation 6 h rats were executed, and dry/wet weight (D/W) ratio of lung was counted, and malondialdehyde (MDA) content, superoxide dismutase (SOD) activity in serum and lung were detected, respectively. In addition, the levels of tumor necrosis factor-α (TNF-α), interleukin-1, -6 (IL-1, -6) of serum were detected.
Results  The MDA contentof serum and lung and the levels of TNF-α, IL-1, IL-6 in model group were markedly higher than those in normal control group and edaravone group, but D/W ratio of lung, SOD activity of serum and lung were significantly lower (P lt;0.05).
Conclusion  Edaravone can alleviate lung injury of rats caused by SAP.
