摘  要:本文应用ABC免疫酶标亲合组织化学技术及粘液组织化学技术对117例胃癌的粘液分泌及双花扁豆凝集素(DBA)受体表达进行了观察。结果显示,胃癌组织DBA受体表达率与癌的组织学类型无关,而与胃癌的组织化学分型有关,其中肠型胃癌的DBA受体表达率及硫酸粘液检出率均显著高于胃型胃癌(P均<0.01)。肠型胃癌的肠化检出率显著高于胃型胃癌(P<0.01),肠型胃癌旁肠化DBA受体表达率显著高于胃型胃癌旁肠化(P<0.05)。结果表明,肠型胃癌可能起源于肠化粘膜特别是柱状细胞分泌硫酸粘液的肠化粘膜。The secretion of mucin and expression of Dolichos biflorus agglutinin(DBA) receptors were investigated in 117 specimens of gastric carcinoma (GC) by mucohistochemical and lectinbinding histochemical staining.The expression rate of DBA receptors was related with the histochemical classification of GC,in which the expression rate of DBA receptors and the prevalence of sulphomucin were significantly higher in intestinal type GC than in gastric type GC(P<0.01).The prevalence of intestinal metaplasia(IM) in intestinal type GC was significantly higher that than in gastric GC(P<0.01).IM associated with intestinal type GC showed significantly higher expression rate of DBA receptors than those associated with gastric type GC(P<0.05).the results indicate that intestinal type GC develops from gastric mucosa with IM,especially those with sulphomucin within mucous columnar cells,,and that gastric type GC arises in “normal” gastric mucosa.
