溶菌酶(Lysozyme)是一种具有溶菌作用的酶,广泛分布于自然界及人体的许多组织和体液之中。目前,体液中溶菌酶活性的测定不仅已在临床医学中得到逐渐应用,而且也被引入预防医学研究行列。本文试从该酶的生化特点和生物学功能、测定方法和正常值及其在预防医学研究中的一些应用作一综述,以供参考。 Lysozyme is a bacteriolytic enzyme widely distributed in nature and in many tissues and body fluids of the body. At present, the determination of lysozyme activity in body fluid has not only been gradually applied in clinical medicine, but also been introduced into the ranks of preventive medicine research. This article tries to review the biochemical characteristics, biological functions, determination methods and normal values ​​of the enzyme and its applications in the field of preventive medicine for reference.
