To investigate the effects of magnetic field exposure (50 Hz, 2 mT) on the growth of adenocarcinoma cells, injected into mice.
Several different experimental protocols in terms of MF exposure timing and tumor injection were tested. A x-radiation (single 10 Gy dose) was used as positive control.
| Exposure | Parameters |
|---|---|
|
Exposure 1:
50 Hz
Exposure duration:
6 h/day, 5 days/week, for 2 or 4 weeks
|
|
exposure was performed in the following way: i) 2 weeks before tumor injection ii) 2 weeks after tumor injection iii) 2 weeks before and 2 weeks after tumor injection iv) 2 weeks with tumor injection on the 3rd day of the 2nd week v) 2 weeks before tumor injection and 10 Gy single dose x-rays
