title: 5-Iododeoxyuridine-125I incorporation in vivo after exposure to a 50 Hz magnetic field.
abstract: CBA male mice were continuously exposed or sham-exposed to 50 Hz magnetic fields (MF) for 54 hours. Cell proliferation was studied by measuring the incorporation of 125IUdR (5-iododeoxyuridine) in whole body and organs such as thymus, thyroid gland, heart, lung, kidney, liver, spleen, testis, stomach, caecum, small intestine and colon. No significant differences were found either in body weights or weights of organs in the MF-exposed animals compared with controls. The incorporation of 125I activity in the whole body and in the organs did not differ between MF-exposed and sham-exposed control animals. In conclusion, the results showed no effects on cell proliferation in mice exposed to a continuous 50 Hz MF, with a flux density of 14 mu T peak-peak (p-p) for 54 hours, at least not detectable with 125IUdR as a tracer during the last 30 hours.
