本文对20例原发性肺癌的石蜡切片和6例刷检涂片进行了银染核仁组成区(AgNOR)染色,并各取肺部良性病变病例对照,对其AgNOR进行了定量分析。结果表明:肺癌核内AgNOR颗粒与对照组在数量上有显著差异(P<0.001),在形态上并有明显不同。该法有助于临床上对肺部良、恶性疾病的鉴别。涂片染色法并有助于临床上提早对肺癌的诊断。
In this paper, AgNOR staining was performed on paraffin sections of 20 cases of primary lung cancer and 6 cases of brush smears. AgNOR was quantitatively analyzed in each case. The results showed that there was a significant difference in the number of AgNOR granules in the nucleus of lung cancer between the control group and the control group (P<0.001). This method is helpful in the clinical identification of benign and malignant lung diseases. The smear staining method is helpful for clinically early diagnosis of lung cancer.
