近年来,对于苯能引起人体细胞的染色体损伤,已日益引起人们的重视。为进一步探讨苯对人体的危害,我们采用了人体细胞染色体G式显带技术与姊妹染色单体差别染色法观察苯对染色体的损伤,以期用接苯人员外周血淋巴细胞在培养条件下的姊妹染色单体交换(SCE)和染色体畸变指标,为慢性苯中毒的早期诊断及远期影响提供细胞遗传学依据。 In recent years, benzene can cause chromosome damage in human cells, which has drawn more and more attention. To further explore the hazards of benzene on the human body, we used human chromosome G-banding technique and sister chromatid differential staining method to observe the chromosome damage of benzene in order to use benzene peripheral blood lymphocytes in culture conditions, sister Chromatid Exchange (SCE) and Chromosome Aberrations, provide cytogenetic basis for the early diagnosis and long-term effects of chronic benzene poisoning.
