胃粘膜肠上皮化生(简称肠化)细胞,可分泌氮——乙酰唾液酸粘液和硫酸粘液。分泌硫酸粘液的肠化与胃癌发生关系密切。本文通过计量法分析硫酸粘液含量与肠化细胞形态的关系以及超微结构特点。材料与方法一、光镜及电镜样品制备:1987年胃手术及胃镜取材标本中,选材有肠化的标本52例(癌旁22例,胃良性病变30例)。经10%甲醛固定,常规脱
Gastric mucosal intestinal metaplasia (referred to as intestinal metaplasia) cells, can secrete nitrogen - acetyl sialic acid mucus and sulfuric acid mucus. Secretion of secreted sulphuric acid mucus is closely related to the occurrence of gastric cancer. In this paper, the relationship between the content of sulfated mucus and the morphology of the intestinal metaplasia and the ultrastructural characteristics were analyzed by the method of measurement. Materials and Methods 1. Light microscopy and electron microscopy Sample preparation: In 1987 gastric surgery and gastroscope specimens were selected 52 cases of intestinal metastases (22 cases of cancer, 30 cases of benign gastric lesions). After 10% formaldehyde fixation, routine removal
