本文报道收集11例鼻咽部上皮组织及30例鼻咽低分化癌活检标本,用树脂包埋,半薄切片定位,超薄切片和电镜观察,并做石蜡切片,光镜观察。对鼻咽部上皮组织电镜观察,可见假复层纤毛柱状上皮中的纤毛柱状细胞,有较发达的粗面内浆网、高尔基体及分泌颗粒(以上三者统称为管泡系统),亦有少量桥粒及微丝;复层鳞状上皮中的棘细胞,有较丰富的微丝、桥粒及
This article reports 11 cases of nasopharyngeal epithelial tissue and 30 cases of nasopharyngeal poorly differentiated cancer biopsy specimens, embedded with resin, semi-thin section positioning, ultra-thin sections and electron microscopy, and paraffin sections, light microscopy. Electron microscopy of the nasopharyngeal epithelium revealed pseudostratified ciliated columnar ciliated cells in the ciliated columnar epithelium, with a more developed intragranular plastron, Golgi and secretory granules (all of which are collectively referred to as the tube system), and also A small amount of desmosomes and microfilaments; stratum spinosum in stratified squamous epithelium, there are more abundant microfilaments, desmosomes and
