作者利用肿瘤坏死细胞显示四环素萤光的特点,以诊断膀胱肿瘤。摄入四环素的膀胱肿瘤患者的浓缩尿,用紫外线显微镜检查,可见到附着于肿瘤细胞上的明亮黄色的四环素萤光。作者对50例膀胱肿瘤、10例急性膀胱炎和10例健康人作对照研究。50例膀胱肿瘤、经膀胱镜检查确定13例是单个肿瘤,37例是一个肿瘤以上。组织学检查6例是乳头状瘤,44例移行细胞癌,所有病例都伴有继发感染。
The authors used the features of tetracycline fluorescence in tumor necrotic cells to diagnose bladder tumors. Intestinal urine of tetracycline-bearing bladder cancer patients was examined by UV-light and bright yellow tetracycline fluorescence was observed on the tumor cells. The author of 50 cases of bladder cancer, 10 cases of acute cystitis and 10 healthy people for controlled study. 50 cases of bladder tumor, cystoscopy confirmed that 13 cases were a single tumor, 37 cases were more than a tumor. Histological examination of 6 cases of papilloma, 44 cases of transitional cell carcinoma, all cases are associated with secondary infection.
