Cytogenetic analysis of chromosomal aberrations (CA) in 175,229 cells from 1113 individuals, both unexposed and occupationally or environmentally exposed to heavy metals (mercury and lead), organic (styrene, formaldehyde, phenol and benzo(a)pyrene) and inorganic (sulfur and nitrogen oxides, hydrogen and ammonium fluorides) volatile substances and/or(More)
Genotoxic properties of the essential oils extracted from dill (Anethum graveolens L.) herb and seeds, peppermint (Menthaxpiperita L.) herb and pine (Pinus sylvestris L.) needles were studied using chromosome aberration (CA) and sister chromatid exchange (SCE) tests in human lymphocytes in vitro, and Drosophila melanogaster somatic mutation and(More)
5,8-Dihydroxycoumarin (5,8-DHC) was isolated from aerial parts of sweet grass (Hierochloë odorata L.) and screened for antioxidant and genotoxic activities. A clear linear dependency of radical scavenging capacity in DPPH• and ABTS•+ assays was determined. 5,8-DHC was very efficient in retarding rapeseed oil oxidation (Oxipress test). TPC (total phenols(More)
The objective of this study was to determine whether nitrofurantoin, used for long-term antimicrobial prophylaxis of urinary tract infection, may induce chromosome aberrations (CAs) and sister chromatid exchanges (SCEs) in lymphocytes of treated children. Ninety-nine blood samples were taken from 69 children aged from 0.2 to 13 years and suffering from(More)
Perchloroethylene (PCE) is the main solvent used in the dry cleaning industry worldwide. The aim of the present work was to evaluate the genotoxic potential of occupational exposure to PCE in dry cleaning workers. The study was carried out in 59 volunteers (30 workers, 29 controls). The genotoxic effect was evaluated by analyzing chromosome aberrations(More)
Chromosome aberration (CA) analysis using Giemsa techniques was performed in blood lymphocytes of 84 nuclear workers with cumulative doses of 1-632 mSv during employment periods of 1-25 y. The control group comprised 82 healthy male donors. An estimated CA frequency in the total radiation-exposed group was significantly higher when compared with the(More)
OBJECTIVE Analysis of cytogenetic alterations in peripheral blood lymphocytes (PBL) of patients with acute and chronic reactive arthritis (AcReA and ChrReA) and rheumatoid arthritis (RA). METHODS The frequencies of sister chromatid exchanges (SCE) and cell proliferative abilities were analysed in PBL from 69 patients with arthritis and 30 healthy(More)
Cytogenetic analysis of chromosome aberrations (CAs) and sister chromatid exchanges (SCEs) was performed in 109 blood samples from 95 pediatric patients with urinary tract infections (UTIs). Children were exposed to diagnostic levels of X-rays during voiding cystourethrography and subsequently treated for one to 12 months with low doses of furagin -(More)
The incidence of chromosome aberrations (CAs) was investigated in cultured lymphocytes of 109 styrene-, formaldehyde-, and phenol-exposed workers in comparison with 64 controls. There was a marked increase in the incidence of the structural chromosome aberrations in the first mitotic division metaphases of occupationally exposed workers (3.59 +/- 0.26(More)
