研究目的(著者による)

To investigate whether chromosomal damage occurrs in blood lymphocytes of railway engine drivers occupationally exposed to 50 Hz magnetic fields.

詳細情報

The blood of 15 exposed railway drivers and 15 guards (which were not exposed to electromagnetic fields according to the authors) as controls was collected. Age and socioeconomic status were similar in individuals from the exposure and the control group. For every individual, three blood vials were examined: 1) blood for chromosome aberration, 2) blood for chromosome aberration with 6 ng/ml mitomycin-C (to check for potential synergistic effects) and 3) blood for sister chromatid exchange.

研究の主なアウトカム(著者による)

No significant differences were seen in any examined parameters between lymphocytes of exposed individuals and those of the control group.
The authors conclude that the study does not indicate that occupational exposure to 50 Hz magnetic fields has a genotoxic effect in railway engine drivers nor that there is a synergistic effect of 50 Hz magnetic fields with mitomycin-C.
