本文探讨消化性溃疡发病机理的形态学改变，选择同一地区经胃镜取材，病理组织学确诊的消化性溃疡（Ｐｕ）患者及正常人（Ｎｓ）作对照研究，应用电子计算机图像分析处理系统及透射电镜技术对胃溃疡（Ｇｕ）、十二指肠球部溃疡（Ｄｕ）及Ｎｓ胃粘膜壁细胞进行体视学分析及超微结构观察。结果为三者间壁细胞平均剖面直径（Ｄ）、平均剖面积（Ｓａ）、平均体积（Ｖｖ）、体积密度（Ｖｖｔ）和数量密度（Ｎｖ）均无显著差异（Ｐ＞０．２）；电镜下Ｄｕ组壁细胞呈分泌活跃相，Ｇｕ及Ｎｓ组则无明显差异。
This article discusses the morphological changes of the pathogenesis of peptic ulcer, select the same area by gastroscopy, pathological diagnosis of peptic ulcer (Pu) patients and normal subjects (Ns) as a control study, the application of electronic computer image processing system and transmission Electron microscopy was performed on the gastric ulcer (Gu), duodenal ulcer (Du) and gastric mucosal parietal cells of Ns for stereological analysis and ultrastructure observation. The results showed that there was no significant difference (P> 0.2) between the average cell diameter of the three cells (D), the average sectional area (Sa), the average volume (Vv), the bulk density (Vvt) and the number density The parietal cells in the Du group were secreted active phase, Gu and Ns group no significant difference.
