Aside from pancreatic enzymes activiation and autodigestive process, recent investigations have established that the upregulation of inflammatory mediator are believed to be the critical steps in the progression of mild pancreatitis to severe pancreatitis. Tumor necrosis factor-, ThyomboxaneA2 ,ProstaglandinsI2 are all important inflammatory mediator. TNF-( is one of cytokines. It is important to the over-production of ICAM-1,VCAM-1, TXA2 andPGI2. The ICAM-1 and VCAM-1 mediate both leukocytes adhesion and migration through the endothelium into tissues to connect with injuried target cells. The TXA2 and PGI2 are the production of arachidonic acid. They are responsible for the tissue ischaemia.
