Interphase cytogenetics of workers exposed to benzene.
Fluorescence in situ hybridization (FISH) is a powerful new technique that allows numerical chromosome aberrations (aneuploidy) to be detected in interphase cells. In previous studies, FISH has been used to demonstrate that the benzene metabolites hydroquinone and 1,2,4-benzenetriol induce aneuploidy of chromosomes 7 and 9 in cultures of human cells. In the present study, we used an interphase ...
متن کاملChromosome translocations in workers exposed to benzene.
As benzene has been linked with elevated risk of both acute myeloid leukemia and lymphoma, we explored the effect of benzene exposure on levels of t(8;21), t(15;17), and t(14;18) translocations. Circulating lymphocytes of normal individuals also often contain t(14;18). Quantitative polymerase chain reaction analysis showed that 37 workers with benzene exposure had a decreased level of t(14;18) ...
متن کاملAn update of mortality among chemical workers exposed to benzene.
Mortality was updated to the end of 1982 for 594 employees exposed to benzene who had been studied previously and for an additional 362 exposed workers not studied previously. Cause specific mortality comparisons were made using United States white male, age, and calendar year adjusted rates. Total mortality was observed to have been significantly below expectation, and this was particularly ev...
متن کاملHematotoxicity in workers exposed to low levels of benzene.
Benzene is known to have toxic effects on the blood and bone marrow, but its impact at levels below the U.S. occupational standard of 1 part per million (ppm) remains uncertain. In a study of 250 workers exposed to benzene, white blood cell and platelet counts were significantly lower than in 140 controls, even for exposure below 1 ppm in air. Progenitor cell colony formation significantly decl...
متن کاملMeasurement of DNA repair deficiency in workers exposed to benzene.
We hypothesize that chronic exposure to environmental toxicants can induce genetic damage causing DNA repair deficiencies and leading to the postulated mutator phenotype of carcinogenesis. To test our hypothesis, a host cell reactivation (HCR) assay was used in which pCMVcat plasmids were damaged with UV light (175, 350 J/m2 UV light), inactivating the chloramphenicol acetyltransferase reporter...
