Chromosome aberrations after exposure to ultrasound.

Stable and unstable chromosome aberrations measured after occupational exposure to ionizing radiation and ultrasound.

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 we used conventional chromosomal aberra...

Analysis of Chromosome Aberrations in Human Lymphocytes after Accidental Exposure to Ionizing Radiation

Aim: Analysis of the results of cytogenetic examination and reconstruction of irradiation doses by the frequency of chromosome aberrations in the liquidators of the consequences of the Chernobyl NPP accident. Materials and methods: Over 1500 people who worked in the zone of the accident predominantly in 1986 and in 1987 have been examined since 1986. All of them were examined by means of the cl...

Reproductive Performance of Mouse Oocyte after In Vivo Exposure of The Ovary to Continuous Wave Ultrasound

Complex chromosome aberrations persist in individuals many years after occupational exposure to densely ionizing radiation: an mFISH study.

Long-lived, sensitive, and specific biomarkers of particular mutagenic agents are much sought after and potentially have broad applications in the fields of cancer biology, epidemiology, and prevention. Many clastogens induce a spectrum of chromosome aberrations, and some of them can be exploited as biomarkers of exposure. Densely ionizing radiation, for example, alpha particle radiation (from ...

Chromosome aberrations in workers exposed to arsenic.

The occurrence of chromosome aberrations was studied in short-term cultured lymphocytes from nine workers exposed to arsenic at the Rönnskär smeltery in northern Sweden. In the smelter workers, 87 aberrations were found in 819 mitoses. The number of aberrations varied individually from 0 to 25 aberrations per 100 cells. In a control material 13 aberrations were found in 1012 mitoses. The freque...
