This study emphasizes the problems encountered in obtaining suitable control levels for comparison with occupational studies of exposure to clastogens. Blood samples taken from 135 individuals (69 females and 66 males) were examined for chromosome aberrations. The data include 15,368 cells scored for chromosome aberrations. The frequencies of chromatid and(More)
Adult male Wistar rats were exposed for 2 h a day, 7 days a week for up to 30 days to continuous 2,450 MHz radiofrequency microwave (rf/MW) radiation at a power density of 5-10 mW/cm(2). Sham-exposed rats were used as controls. After ether anesthesia, experimental animals were euthanized on the final irradiation day for each treated group. Peripheral blood(More)
PURPOSE We investigated genotoxic effects of occupational exposure to lead acetate in pottery-glaze ceramic workers. METHODS The study was carried out in 30 exposed workers and 30 matched controls, to whom several biochemical parameters-the blood lead (B-Pb; range: exposed, 41.68-404.77; controls, 12-52) and cadmium (B-Cd) level, the activity of(More)
This study was aimed at investigating the genotoxic potential of single beauvericin (BEA) and ochratoxin A (OTA) as well as their interaction in porcine kidney epithelial PK15 cells and human leukocytes using the alkaline comet assay. IC50 of BEA (5.0 ± 0.6) and OTA (15.8 ± 1.5) estimated by MTT reduction assay shows that BEA is three times more toxic than(More)

Radionuclides released into the biosphere by local sources are added to artificial radionuclides introduced by atmospheric nuclear weapon tests or nuclear accidents. The main polluters are nuclear industry reprocessing plants and nuclear power stations. Other sources are hospitals using radionuclides for diagnostics and therapy. This article presents the(More)
Mercury is a toxic element which is easily absorbed after ingestion or inhalation and deposited mainly in the kidney. The aim of this study was to evaluate the effects of mercury chloride in rats. Female rats, aged 14 weeks, were receiving mercury chloride in oral doses of 0.068, 0.136, and 0.272 mg kg(-1) body weight (b.wt.) for five consecutive days.(More)
Genetic damage induced by anaesthetic gases in occupationally exposed populations was investigated using the comet assay and micronucleus test. The study included two groups of subjects: 50 operating theatre medical workers (anaesthesiologists, technicians and nurses) and 50 control subjects corresponding in sex, age and smoking habit. The exposed group(More)
AIM To evaluate chromosome aberration and fluorescent in situ hybridization (FISH) assays as a method to estimate of health risk, we monitored 9 male subjects occupationally exposed to low doses of both ionizing radiation and ultrasound during a period of over 3 years. METHODS Sampling was performed at 6-month intervals during a three-year period. First(More)
The aim of the present study was to evaluate genome damage induced in peripheral blood lymphocytes of Croatian health care workers occupationally exposed to cytotoxic drugs. A comprehensive multi-biomarker approach using the alkaline comet assay and cytogenetic endpoints (analysis of structural chromosome aberrations, SCE assay, lymphocyte proliferation(More)
Medical staff is an occupational group exposed to different agents suspected to induce genetic damage. Among them ionising radiation is the most studied. Cytogenetic analysis of human chromosomes in peripheral lymphocytes allows direct detection of mutation in somatic cells. This study investigated the cytogenetic effects of low-level ionising x-radiation(More)
