目的  了解內(nèi)皮素對大鼠急性胰腺炎的影響。
方法  應(yīng)用蛙皮素及高分子右旋糖酐造成大鼠急性水腫性和出血壞死性胰腺炎模型，觀察血漿內(nèi)皮素水平及其它相關(guān)指標(biāo)，同時(shí)觀察外源性內(nèi)皮素對水腫性胰腺炎大鼠血清淀粉酶、6-Keto-PGF1α及胰腺組織病理形態(tài)等的影響。
結(jié)果  出血壞死組大鼠血漿內(nèi)皮素水平明顯升高，與水腫組相比差異有顯著性意義(Ｐ＜0.01)； 一定劑量的外源性內(nèi)皮素可促使水腫性胰腺炎向出血壞死性轉(zhuǎn)化，胰腺組織損害程度與血漿內(nèi)皮素水平呈正相關(guān)。
結(jié)論  內(nèi)皮素參予了急性胰腺炎的發(fā)生發(fā)展，并在水腫性胰腺炎向出血壞死性胰腺炎的轉(zhuǎn)化過程中起重要作用。
