To study the effects of exposure to electromagnetic fields with different frequencies in a mouse epilepsy model.
180 mice were investigated: 1.) control group, 2.) exposure to 900 MHz, 3.) exposure to 700 MHz, 4.) exposure to 500 MHz, 5.) exposure to 300 MHz and 6.) exposure to 100 MHz. The groups were divided into subgroups and exposed for 2, 12 (or 10? Remark EMF-Portal: contradictory data) or 20 hours (10 mice per subgroup). After exposure, mice were injected with 60 mg/kg pentylenetetrazole. The control group was treated after the same duration like the exposure groups. Afterwards, mice were monitored for 20 minutes.

The mean latency to onset of initial seizure of the 2 hours-exposed group was significantly shorter than those of the 12 and 20 hours-exposed groups. There was a significant difference in the latency to onset of initial seizure between the mean (?) values of the control group and the 2 and 10 (12?) hours-exposed group (remark EMF-Portal: not clear what difference).
No statistically significant differences were found in the latencies of the most severe reaction.
