【Abstract】Objective To investigate the role of interleukin-10(IL-10) and interleukin-18 (IL-18) in the pathogenesis of acute lung injury in experimental severe acute pancreatitis.
Methods Forty-eight SD rats were divided into control group and SAP group by the random data table. The model of experimental severe acute pancreatitis was established by injection of 3.5% sodium taurocholate into the bili-pancreatic duct. Lung wet weight index, ascities and level of serum amylase, IL-10 and IL-18 were quantitatively measured in different time. Intrapulmonary expressions of IL-10 mRNA and IL-18 mRNA were detected by semiquantitative RTPCR. The histopathology of pancreas and lung were observed under the light microscope.
Results Lung wet weight index, ascities, level of serum amylase, IL-10 and IL-18, intrapulmonary expressions of IL-10 mRNA and IL-18 mRNA were significantly increased in SAP group (P<0.01). The level of serum IL-18 and intrapulmonary expression of IL-18mRNA are positively correlated with lung wet weight index (r=0.68,P<0.01; r=0.72,P<0.01) and lung injury score (r=0.74,P<0.01; r=0.79,P<0.01) respectively, whereas the level of serum IL-10 and intrapulmonary expression of IL-10 mRNA are negatively correlated with lung wet weight index(r=-0.62,P<0.01; r=-0.69,P<0.01) and lung injury score(r=-0.66,P<0.01; r=-0.60,P<0.01).
Conclusion IL-18 may play a key role in the pathogenesis of acute lung injury in experimental severe acute pancreatitis, and IL-10 exerts the protection role in this process.
