摘要
本文报告了１７０例肺内各种肿瘤性病变的ＡｇＮＯＲｓ检测结果。结论是：瘤样病变和良性瘤与各恶性瘤的组间差异非常显著（Ｐ＜０．０１）．鳞癌和腺癌的高、中、低不同分化组之间无显著差异。肺内易于误诊为腺癌的腺样化生区，其ＡｇＮＯＲｓ值与正常上皮相似，但有明显增生并有一定异型的上皮部分，其ＡｇＮＯＲｓ值与恶性肿瘤相接近。作者认为：肺内瘤样及肿瘤病变的ＡｇＮＯＲｓ测定对肿瘤病变的良恶性诊断有重要的辅助诊断作用。
ilver-binding Nucleolar Organizer Regions(AgNORs)were quantitavely countedin 170 cases of pulmonary tumors.The ultrastructure of NORs in 6 cases were obser-ved with electronic microscopy,It is considered that AgNORs counting might be a usefulindicator to differentiate between benign or tumor-like lesions with malignant tumors.AgNORs value of low-malignant tumors(such as carcinoid, mucoepithelial tumor,ade-nocystic carcinoma)might be between that in benign and malignant tumors,while thereWere no significant differences in groups of high-middle-low differentiation of squa-mous and adenocarcinoma in lung cancer,among high,middle and low malignantsquameus careinoma or adenocarcinoma of lung。
