胃蛋白酶原(PG)是胃底腺分泌的一种蛋白酶前体,分泌入胃腔后约有1％进入血流,其中有部分经尿排除。已证实PG分泌能力与泌酸能力,以及两者与血清及尿PG浓度之问有很强的关联。由于测定血清PG的放射免疫法基层很难普及,因此我们设计了从尿中检测PG的一种简便方法,并对正常成人,慢性浅表性胃炎(CSG)及十二指肠溃疡(DU)患者作了检测研究。 Pepinoid (PG) is a protease precursor secreted by the fundus gland, secreted into the gastric cavity about 1% into the bloodstream, some of which were excluded by urine. PG secretion capacity has been confirmed with acid secretion, as well as both serum and urinary PG concentrations have a strong correlation between Q. Since radioimmunoassay of serum PG is difficult to detect, we designed a simple and convenient method for the detection of PG from the urine and evaluated normal adults, chronic superficial gastritis (CSG) and duodenal ulcer (DU) The patient made a test study.
