本文对甲状腺癌、腺瘤及非典型增生细胞进行AgNOR计数与DNA倍体分析。结果表明从正常甲状腺滤泡细胞及甲状腺腺瘤至非典型增生及甲状腺癌细胞AgNOR均数及DNA多倍体或非整倍体均随病变程度的加重而递增,两者相关有显著性(r=O.7,P<0.01)。甲状腺癌≥6C细胞高达25.6％,直方图趋于弥散、低平或多峰形。对此,我们认为AgNOR计数和DNA含量的检测均能反映甲状腺滤泡上皮细胞不同程度的增殖状态。 In this paper, AgNOR counts and DNA ploidy analysis were performed on thyroid cancer, adenoma, and atypical hyperplasia. The results showed that from normal thyroid follicular cells and thyroid adenomas to atypical hyperplasia and thyroid cancer cells, the AgNOR mean and DNA polyploidy or aneuploidy increased with the severity of the lesions, and the correlation between them was significant (r). =O.7, P<0.01). Thyroid cancer ≥ 6C cells are as high as 25.6%, and the histogram tends to be diffuse, low-level or multi-peaked. In this regard, we believe that the detection of AgNOR counts and DNA content can reflect different degrees of proliferation of thyroid follicular epithelial cells.
