ASP model was established by injecting with 35 g/L taurocholic acid into the biliopancreatic duct. Both groups were sacrificed at 3, 6 and 12 h with 8 rats at each time point. At scheduled time, bronchoalveolar lavage fluid was drawn and PMNs were then obtained by gradient density gradient centrifugation method. The ratio of apoptosis and necrosis of PMN was assayed by flow cytometry and LDH as well as index of lung permeability were measured.
