【摘要】 对５５例淋巴结石腊包埋切片进行了核仁组成区相关嗜银蛋白（ＡｇＮＯＲｓ）定量研究。结果表明：３１例恶性淋巴瘤Ａｇ－ＮＯＲｓ计数为６．６２±３．０２，２４例良性淋巴结病变为１．６９±０．４７，两组比较有极显著差异（Ｐ＜０．０１）；在非何杰金淋巴瘤（ＮＨＬ）中，低度恶性组Ａｇ－ＮＯＲｓ计数为３．７９±１．４６，而中、高度恶性组为８．２８±２．５８，两组间亦有极显著差异（Ｐ＜０．０１）；何杰金病（ＨＤ）与ＮＨＬ间无显著差异（Ｐ＞０．０５）。结果提示，Ａｇ－ＮＯＲｓ技术简便、快速、实用，对淋巴结良恶性病变的鉴别及恶性淋巴瘤的病理分级，可提供有价值的形态学资料。更多还原

【Abstract】 Using silver colloid technique, nucleolar organizer region-associated argyrophilic proteins(Ag-NORs)were studied quantitatively in the biopsy of lymph nodes from 55patients. The results showed that the Ag-NORs count was 6.62±3.02 in 31 lymph nodes with malignant lymphoma and 1.69±0.47 in 24 lymph nodes with benign changes, the difference being significant(P<0.01). In non-Hodgkin’s lymphoma, the Ag-NORs count was significantly higher in cases of low-degree differentiation than in cases of high-degree differentiation(P< 0.01). This technique may be valuable in the study of the differential diagnosis between the benign and malignant lmmph nodes and in the grading of non-Hodgkin’s lymphoma.更多还原
