自1949年Balo和Banga首次在哺乳动物胰腺内发现胰弹力蛋白酶,迄今已30余年。近年来,由于其同工酶的发现及检测技术的发展而重新引起重视。据报道胰弹力蛋白酶(pancreatic elastase,PE)及其同工酶对胰腺疾病的诊断有重要意义。除胰腺外,弹力蛋白酶还广泛存在于大动脉壁、白细胞、巨噬细胞、 Balo and Banga first discovered pancreatic elastase in the mammalian pancreas for more than 30 years. In recent years, due to the discovery of its isoenzyme and the development of detection techniques to re-pay attention. It has been reported that pancreatic elastase (PE) and its isoenzymes are important for the diagnosis of pancreatic diseases. In addition to the pancreas, elastase is also widespread in the arterial wall, white blood cells, macrophages,
