為了解急性壞死性胰腺炎(acute necrotizing pancreatitis，ANP)時血漿內皮素(endothelin，ET)的變化及其病理意義，進行了前瞻性動物實驗。即將SD大鼠隨機分為3組：急性壞死性胰腺炎組(ANP組，n＝24)，經膽胰管注入5%牛磺膽酸鈉(STC，1 ml/kg)制造ANP模型；假手術組(SO組，n＝24)和血小板激活因子拮抗劑BN50739組(BN組，n＝24)。測定血漿ET及血小板激活因子(platelet activating factor，PAF)水平和胰腺微循環血流量，并進行胰腺組織病理學評分。結果： ANP組在誘發胰腺炎后胰腺微循環血流量立即大幅度下降，于3小時時有所回升，以后再持續下降。血漿ET、PAF水平及病理記分均顯著高于SO組。BN組血流顯著改善，血漿ET、PAF水平及病理記分顯著低于ANP組。結論：在STC誘發的大鼠ANP發病之初，存在胰腺缺血再灌注(I/R)現象，導致內皮細胞損傷，血漿ET及PAF增加。I/R損傷、PAF與ET互相作用，形成惡性循環，加重胰腺病變。
