胃蛋白酶原(PG)是胃底腺分泌的一种蛋白消化酶前体,依其电泳迁移率和免疫原性的不同分为7个组分,两个亚群。为了探讨血清胃蛋白酶原亚群Ⅰ、Ⅱ(SPGⅠ.SPGⅡ)对胃病辅助诊断的价值,我们进行了下列研究:
Pepsinogen (PG) is a proteolytic enzyme precursor secreted by the fundus glands and is divided into 7 components and 2 subpopulations depending on the electrophoretic mobility and immunogenicity. To investigate the value of serum pepsinogen subpopulations I and II (SPGI.SPGII) in the diagnosis of gastritis, we conducted the following studies:
