ABSTRACT
Objective To establish a rat model of acute lung injury (ALI) induced by intraperitoneal injection of pancreatitis associated ascitic fluids (PPAF) and perforative peritonitis ascitic fluids (PAAF).A secondary objective is to study the non-specificity of acute lung injury induced by PAAF.Methods Acute necrotizing pancreatitis (ANP) model and perforative peritonitis (PP) model were established in 120 rats,from which the PAAF and PPAF were collected.Forty-eight rats were randomly divided into three groupsnormal saline (NS) group,PAAF group,and PPAF group.Within each group,they were randomly sacrificed at 7h and 12h of surgery.The pathological severity of the lung injury,wet/dry ratio,MPO (myeloperoxidase) in lung,and apoptosis rate of pneumocytes were evaluated and analyzed.Results Lung injury,wet/dry ratio,MPO in lungs,and cell apoptosis were significantly higher in the PAAF group and PPAF group than in the NS group (P<0.01).However,there was no significant difference between PAAF group and PPAF group (P>0.05).Conclusions Both PAAF and PPAF can induce acute lung injury in rats by intraperitoneal injection.However,the acute hung injury induced by PAAF has limited specificity.
