摘要
电镜观察胃粘膜不典型肠化生区时见到一种异型壁细胞。细胞内分泌小管的微绒毛呈上宽下狭,分叉迷路状。微绒毛表面有浓密的茸状细胞衣,在微绒毛的底部细胞质内见球拍状,小泡状结构系微管泡系统的残迹。线粒体明显减少,高尔基复合体显现。
We discovered an atypical parietal cell with feature of intestinal microvillia in intestinal metaplasia of gastric mucosa. The short and divergent microvillia projected in o the secretive tubule of parietal cell and had dense cell coat and long microfilaments. The surviving micro tubulovesiclas system was in the base of microvillia, but the mitochondria decreased and autophagocytosis became visible. It suggested that the intestinal metaplasia of gastric mucosa had adepted to the basic microenvironment just as the gastric epithelia metaplasia in duodenum achieved the aim of anti-high gastric acid.
