细胞核仁组成区嗜银蛋白(nucleolar orga nizer region-associated protein,AgNOR)颗粒数量的变化已被用于肿瘤的良恶性鉴别研究。近年来,AgNOR大小的改变在研究细胞恶变中的意义越来越受到人们的重视。本法用图像分析技术对胃粘膜异型增生及胃癌标本的
The changes in the number of nucleolar orga nizer region-associated protein (AgNOR) particles have been used in the differential diagnosis of benign and malignant tumors. In recent years, the significance of the change in the size of AgNOR has become more and more important in the study of cell malignant transformation. This method uses image analysis techniques for gastric dysplasia and gastric cancer specimens
