胃泌素(Gastrin)是胃窦部及十二指肠近端粘膜中胃泌素细胞(又称G细胞)分泌的一种多肽类胃肠道激素,它在人的消化功能中占有相当重要的地位。为了探讨胃泌素的生理作用以及在某些消化系统疾病时血清胃泌素值的变化,国内外许多学者做了大量的研究工作。由于胃泌素在外周血液中含量甚微,故用一般的生化方法无法测定,而目前应用的放射免疫测定法则具有灵敏度高、特异性强、精确性好、标本和试剂的用量少及操作简便等优 Gastrin is a polypeptide gastrointestinal hormone secreted by gastrin cells (also known as G cells) in the gastric antrum and proximal mucosa of the duodenum. It is very important in human digestive function. The status. In order to investigate the physiological role of gastrin and the change of serum gastrin value in some digestive diseases, many scholars at home and abroad have done a lot of research work. Since gastrin is contained in a small amount in the peripheral blood, it cannot be measured by general biochemical methods. However, currently applied radioimmunoassay methods have high sensitivity, specificity, accuracy, and use of small amounts of specimens and reagents, and operations. Simple and convenient
