核仁组成区(nucleolar organizer region)可用银染的方法(简称 AgNOR)显示,这已被一些学者用于肿瘤的研究,发现对许多肿瘤良、恶性的鉴别及分型分级有用。我们测定了慢性胃炎、胃癌前状态、胃癌前病变和胃癌上皮细胞内 AgNOR,以探讨胃癌前状态组织中核仁组成区的变化及临床意义。
The nucleolar organizer region (AgNOR) can be used as a silver staining method. This has been used by some scholars for tumor research and has been found to be useful for the identification and classification of many types of tumors. We measured AgNOR in chronic gastritis, precancerous conditions, precancerous lesions, and gastric cancer epithelial cells to investigate the changes and clinical significance of nucleolar composition in precancerous tissues.
