胃粘膜中的上皮细胞和腺体能产生和分泌含有不同糖组份的各种粘蛋白,由于粘膜病变常伴有粘蛋白分泌的改变,故检测正常及病变胃粘膜组织中粘蛋白的分布日益受到重视。胃粘膜上皮细胞中的糖连接物及分泌的粘蛋白均含有一定比例的寡糖链,主要含有甘露糖、半乳糖、N-乙酰氨基半乳糖、N-
Epithelial cells and glands in the gastric mucosa produce and secrete a variety of mucins with different sugar components. Because mucosal lesions are often accompanied by changes in mucin secretion, the distribution of mucin in normal and diseased gastric mucosa is increasing. It is valued. Glycoconjugates and secretory mucins in gastric epithelial cells contain a certain proportion of oligosaccharide chains, mainly containing mannose, galactose, N-acetylgalactose, N-
