One hand mechanical obstruct led to the increase of veinous resistance and the obstacle of microcirculation, the other hand the adhesive PMN was activated in excess, the white blood cells released a lot of enzymes, in which PMN-elastase can decompose the components of cell and many albumens, inclusive of immunoglobulin、alexin and fibrication. These components induced the injury of the pancreatic capillary vessels and cell and lysosome enzy made the tissue protein hydrolyze and produced unsaturated fatty acids, which destroyed the structure and function of cellar membrane. The inflammatory cellar factors activate other immunocytes to produce the injury and necrosis of tissue, which aggravated the pathological injury and led to shock、pyaemia and MODS. So ICAM-1 and LFA-1 played an important role in SAP. Frossard found that the expression of ICAM-1 in the rat model, especially in serum、pancreas and lung. All these showed ICAM-1 is an important factor in AP and concomitant lung injury.

胰腺小叶组织局部血管EC首先被激活，ICAM-1表达升高，与被激活的PMN表面表达的LFA-1相结合，"PMN-EC"相互作用加剧，一方面机械性阻塞毛细血管导致静脉阻力增加、微循环障碍；另一方面粘附的PMN过度吞噬或激活，当白细胞吞噬的颗粒不能被封闭隔离，连同细胞内的酶被释放出来，其中的PMN-elastase能够降解细胞基质中各种成分，水解多种蛋白，加重胰腺的毛细血管内皮细胞和腺泡的损伤；释放的溶酶体酶使组织蛋白水解，产生的不饱和脂肪酸引发脂质过氧化方应，破坏细胞膜的结构和功能；释放的炎性细胞因子，激发其他的免疫细胞的功能，导致进一步的组织损伤和坏死，加重SAP的病理损伤，最终导致休克、脓毒血症及多器官功能障碍等严重后果。
