用免疫过氧化物酶技术和单克隆抗体技术观察了膀胱移行上皮痛及其周围组织中的淋巴细胞亚群。发现肿瘤和距肿瘤2cm的组织大多数没有或有散在T淋巴细胞和M+浸润,少部份有较多上述细胞浸润。肿瘤间质和粘膜固有层浸润多于肿瘤实质和粘膜上皮层;T_4细胞多于T_8细胞;远离肿瘤的膀胱组织免疫细胞浸润少,免疫细胞的浸润程度和肿瘤分期呈正相关;免疫细胞聚集部位未见肿瘤细胞坏死。 Immuno-peroxidase technique and monoclonal antibody technique were used to observe the lymphoid subpopulation in bladder transitional epithelial pain and its surrounding tissues. Most of the tumors and 2 cm away from the tumor were found to have no or diffuse T-lymphocytes and M infiltration, with fewer of these cells infiltrated. Tumor interstitial and mucosal lamina propria infiltration more than the tumor parenchyma and mucosa epithelial layer; T 4 cells more than T 8 cells; away from the tumor of bladder tissue less immune cell infiltration, immune cell infiltration and tumor stage was positively correlated; immune cell aggregation site See tumor necrosis.
