The findings of the newly identified goose paramyxovirus strain GPMV/HBexperimental infection were as follows: The challenge caused high morbidity and highmortality.The clinical signs included severe depression, decreased appetite or anorexia,white,yellow and green diarrhea, with neural symptoms;pathological changes showed thathaemorrhage and ulceration of intestine mucosa, necrosis of spleen and pancreas,andedema of liver and kidney, uratic deposition in kidney.Eosinophilic inclusion bodies werefound in the cytoplasm of pancreas and a large quantities of fiber protein were found inintestine. Lots of hemosidefin was found in some area of liver and kidney. A number ofT、B lymphocytes reduced sharply in spleen,lymph nodes in dead geese. Transmissionalelectron microscope showed that some cells had the morphological characteristics ofmitochondria swelling, morphological changes were condensation of nuclear chromatininto dense masses,followed by its marginating against the nuclear envelope, andespecially concentration of cytoplasm association with lots of lipid droplet.

人工感染雏鹅实验中，雏鹅临床表现为高发病率和高死亡率，食欲和饮水减少，拉白色、黄绿色稀粪，伴有神经症状；常规组织学观察，脾脏和胰腺肿大，有白色坏死斑点，肠道出血和坏死，肝脏肿大变性，肾脏肿大变性有尿酸盐沉着等；用特殊染色和组织化学方法首次对人工感染鹅副粘病毒的雏鹅的重要脏器进行研究，结果表明：胰腺中发现病毒包涵体，肠道中大量纤维素以及胶原纤维增生，肾脏、肺脏大量含铁血黄素沉着，免疫器官如脾脏和淋巴结中T、B淋巴细胞大量减少；电镜下多种细胞呈现线粒体水肿，多种实质细胞的染色质固缩，染色质边集，特别是细胞内容物如脂肪滴增多的病理变化特征。

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。
