目的探讨巴氏分级法在联苯胺接触人群尿脱落细胞检查中的应用。方法用巴氏分级法和吖啶橙染色法对50例联苯胺接触工人尿脱落细胞涂片进行染色,比较两者阳性结果。结果在一年的周期内,两种方法检出例数相等;但在3个月监护周期内,巴氏分级法可再次测得新增阳性病例。结论通过巴氏分级法,能达到对职业性膀胱癌早发现、早治疗的目的。 Objective To investigate the application of Papanicolaou in the examination of urine exfoliated cells in exposed groups of benzidine. Methods Pap test and acridine orange staining were used to stain urine exfoliated cells of 50 workers exposed to benzidine, and the positive results of the two methods were compared. Results In the one-year cycle, the two methods detected the same number of cases; however, in the three-month custody cycle, the positive cases could be measured again by Pap test. Conclusion Papanicolaou grade can achieve the purpose of early detection and early treatment of occupational bladder cancer.
