电镜在消化道疾病诊断中的应用

The Apply of Electron Microscope in The Diagnosis of Diseases of Digestive Tract

本文应用透射及扫描电镜结合冷冻断裂技术；免疫组化、免疫电镜技术及电镜酶细胞化学技术等对消化道疾病—慢性萎缩性胃炎、胃癌及其癌前病变进行了细胞及超微水平的定位观察，重点探讨其发病机理及病变特点。

This article apply the transmission and scanning electron microscope combine with freeze fracture technique, the immunohistological and immunoelectron microscopic technique and the electron microscopic cytochemical technique to observe the diseases of human digestive tract-chroric atrophic gastritis, gastric cancer and its precancerous lesions at cell and ultrastructural level. The pathogensis and pathologic changes are discussed. It provide the morphologic basis for the early diagnosis and prevent of the above diseases.
