促胃液素(gastrin,GAS)旧称胃泌素,是英国学者Edlkine于1905年首次发现并命名的。自促胃液素放射免疫分析方法(RIA)建立后,促胃液素的临床应用越来越广泛,现就促胃液素在消化道肿瘤诊治中的应用进展作一综述。1促胃液素的生物学特性促胃液素是由胃窦和十二指肠G细胞分泌的多肽 Gastrin (GAS) formerly known as gastrin, was first discovered and named by British scholar Edlkine in 1905. Since the establishment of gastrin radioimmunoassay (RIA), the clinical application of gastrin is more and more widely. The application of gastrin in the diagnosis and treatment of gastrointestinal tumors is reviewed. 1 gastrin biological characteristics Gastrin is secreted by the gastric antrum and duodenal G cells of the polypeptide
