应用抗酸（ＩＫ）染色和结核菌抗体（ＢＣＧ）、增殖细胞核抗原（ＰＣＮＡ）免疫组化染色方法，对１１９例膀胱肿瘤及炎症进行了检测。结果显示：ＩＫ抗酸染色、ＢＣＧ免疫组化染色阳性率分别为：膀胱癌为３５２、３６７％；乳头状瘤为４０％、４４％；慢性炎为４２３％、５０％。ＰＣＮＡ阳性细胞指数膀胱癌与粘膜慢性炎比较差异非常显著（Ｐ＜０００１）；乳头状瘤与慢性炎比较差异显著（Ｐ＜００５）。提示结核菌Ｌ型感染与肿瘤的发生和发展可能有关
119 cases of bladder tumor and inflammation were detected by anti-acid (IK) staining, anti-tuberculosis antibody (BCG) and proliferating cell nuclear antigen (PCNA) immunohistochemical staining. The results showed that the positive rate of IK acid-fast staining and BCG immunohistochemical staining were 35.2% and 36.7% for bladder cancer, 40% and 44% for papilloma, 42.3% and 50% for chronic inflammation %. PCNA positive cell index bladder cancer and mucosal chronic inflammation was significantly different (P <0 001); papilloma and chronic inflammation were significantly different (P <0 05). Tip L tuberculosis infection and tumor occurrence and development may be related
