摘要
核仁组成区NORs(nucleolar organizer regions,NORs)是位于细胞核仁中的DNA片断,含有rRNA的基因,其数量和构型常反映细胞的活性。利用银染方法可显示与NOR相关的一些蛋白,即核仁组成区相关嗜银蛋白(AgNORs)。本文利用AgNORs染色法对49刮皮肤良恶性肿瘤进行了定量定性研究,以探讨其对良恶性肿瘤的鉴别诊断价值。结果表明,AgNORs计数的差别在皮肤良恶性肿瘤之间是十分显著的。
Forty-nine cases of benign and malignant dermatotumors were investigated on quantity and quality by AgNOR staining. The aim is to determine the role of AgNOR staining in differential diagnosis. The results demonstrated that AgNOR staining was valuable in diffrential diagnosis.
