ABSTRACT
Objective To observed the expression of matrix metalloproteinase-9 in the early onset of severe acute pancreatitis associated with acute lung injury in rats and investigate its effection in lung injury.Methods Thirty-two healthy adult male SD rats were randomly divided into two groupsControl group (n =8),Severe acute pancreatitis group(n =24).Severe acute pancreatitis model was induced by retrograde inject the 4% sodium taurocholate sodium taurocholate into the biliopancreatic duct of rats.The severe acute pancreatitis group was detected the rate of lung water content、arterial blood gas.myeloperoxidase,matrix metalloproteinase-9,histopathology of the pancreas and lung injury score under the light microscope at 3 hours,6 hours and 12 hours.The matrix metalloproteinase-9 expression was detected by immunohistochemical and the results of immunohistochemical were analysed by the Image-Pro Plus image analysis system.Control group was detected the relevant indicators at 12 hours.Results Successfully modeling,the expression of matrix metalloproteinase-9 gradually increased beginning at 3 hours,at twelve hours up to the highest value(P < 0.05).The degree of lung injury,lung water content,myeloperoxidase activity,PaCO2 gradually increased(P < 0.05),PaO2 decreased significantly P < 0.05).Conclusions The high expression of matrix metalloproteinase-9 is important to the pathogenesis of severe acute pancreatitis associated with acute lung injury.
