Abstract
We studied the influence of magnetic fields (MFs) and simulated solar radiation (SSR) on ornithine decarboxylase (ODC) and polyamines in mou se epidermis. Chronic exposure to combined MF and SSR did not cause pe rsistent effects on ODC activity or polyamines compared to the animals exposed only to UV, although the same MF treatment was previously fou nd to accelerate skin tumor development. In an acute 24-h experiment, an elevation of putrescine and down-regulation of ODC activity was obs erved in the animals exposed to a 100-mu T MF. No effect was seen 24 h after a single 2-MED (minimal erythemal dose) exposure to SSR. The re sults indicate that acute exposure to 50 Hz MF does exert distinctive biological effects on epidermal polyamine synthesis. (C) 1998 Wiley-Li ss, Inc.
