Objective:To investigate the effect of salvia miltiorrhiza on expression of the MMP-2、9 and TIMP-1、TIMP-2 in tissue of acute lung injury of severe acute pancreatitis(SAP).Methods:MMP-2、9 expression and changes of the lung were measured after the SAP rats were induced by retrograde injection of 5%sodium tauocholate into hepatopancreatic duct.The changes of those parameters were also measured after salvia miltiorrhiza was injected intramuscularly just after induction of SAP.Results:The level of MMP-2、9 in pancreas and lung in SAP group were significantly higher than those in sham;The level of MMP-2、9 in salvia miltiorrhiza group were significantly lower than those in SAP group. Conclusion:MMP-2、9 were overexpressed in Acute lung injury (ALI) induced by SAP, salvia miltiorrhiza downregulates MMP-2、9 expression and decreased injury of lung tissue.
