原发性肺癌是我国最常见的癌瘤之一。本文观察了12例原发性肺癌术后标本的超微结构,结合光镜进行对比研究。对照病理诊断、从组织发生角度认识其形态变化。尝试细胞亚显微结构水平的病理分类分型标准。12例术后标本及时常规电镜处理,国产711环氧树脂包埋。切成1微米的半薄切片,苏木素伊红染色,选区再制成超薄切片及半薄切片,铀、铅染色, Primary lung cancer is one of the most common cancers in our country. This article observed the ultrastructure of 12 cases of primary lung cancer after surgery, combined with light microscopy for comparative studies. The pathological diagnosis was compared with the morphological changes from the perspective of histogenesis. Try to determine the sub-microscopic structure of the cell’s pathological classification criteria. Twelve specimens were processed by conventional electron microscopy in a timely manner, and domestic 711 epoxy resin was embedded. Cut into semi-thin sections of 1 micron, stain with hematoxylin and eosin, reconstitute the area into ultra-thin sections and semi-thin sections, stain with uranium and lead,
