Abstract:
Objective To explore the potential role of cytokine-induced neutrophil chemoattractant (CINC) and monocyte chemoattractant protein-1/JE (MCP-1/JE) in the pathogenesis of early acute pancreatitis(AP). Methods Acute edematous pancreatitis(AEP) and acute necrotizing pancreatitis(ANP) were induced by retrograde infusion of 0.5% or 5% sodium taurocholate into the biliary pancreatic duct. The activity of serum amylase and the level of serum calcium were studied, wet to weight ratio,the activity of myeloperoxidase (MPO) and pathological changes of pancreas were observed. The expression of gene and protein of CINC and MCP-1/JE in pancreatic constitution were detected. Results Compared with that in controls,pancreatic acinar cells were found to express CINC and MCP-1/JE protein in certain intensity. With the induction and the progress of AP,the expression of the activity of MPO,CINC and MCP-1/JE gene in pancreatic parenchyma were all significantly increased ( P
