核仁组成区银染法(简称AgNORS).近年被引进肿瘤病理学的研究,一般认为是肿瘤研究的一项新指标‘。但应用于鼻咽癌组织的研究,报道极少。本文试以鼻咽活检石蜡包埋组织,应用此技术。进行计数研究,探讨其在鼻咽粘膜上皮良、恶性病变细胞的鉴别诊断价值。 材料与方法 本文收集我科1989年6月至12月间,全部鼻咽活检组织101例(经10％甲醛固定,石蜡包埋)。其中鼻咽低分化浸润癌61例(无腺癌);鼻咽慢性炎症40
The nucleolar organizing region silver staining method (abbreviated as AgNORS) has been introduced into the study of tumor pathology in recent years and is generally considered to be a new indicator of tumor research. However, there are few reports on the application of nasopharyngeal carcinoma. This article uses a nasopharyngeal biopsy paraffin-embedded tissue to apply this technique. A counting study was conducted to investigate the differential diagnostic value of benign and malignant lesions in nasopharyngeal epithelium. Materials and Methods This article collected 101 cases of nasopharyngeal biopsy from June to December 1989 in our department (fixed with 10% formaldehyde and embedded in paraffin). Among them, 61 cases of poorly differentiated infiltrating nasopharyngeal carcinoma (no adenocarcinoma); chronic inflammation of nasopharyngeal 40
