摘　　要：采用银染核仁形成区技术，研究了７６例涎腺肿瘤的核仁形成区（ＮＯＲ），用图象分析系统观察ＡｇＮＯＲ的形态，计数其数量和测量其直径及面积。结果表明，ＡｇＮＯＲ计数值、面积和直径基本上与肿瘤的生物学行为平行，其差异在三组肿瘤间有统计学意义（Ｐ＜０．０１）。ＡｇＮＯＲ计数值与其直径或面积间存在负相关关系，而面积与直径间则存在密切的正相关关系。表明结合ＡｇＮＯＲ计数值及其直径或面积，更有助于对涎腺肿瘤作出鉴别诊断。A series of 76 cases of salivary gland tumors had been studied by means of the argyrophil(AgNOR)technique and morphometric analysis of the AgNOR was performed with an image analysis system.The results showed that the AgNOR count and its size seemed to correlate with the biological behavier,and an inverse relationship between AgNOR numvbers and their sizes.These findings suggested that analysis of the AgNOR numbers and sizes might be helpful for the differentiation of salivary gland tumors.
