No effect of pulsed electromagnetic fields on PC12 and HL-60 cells.
Published in: Radiat Environ Biophys 2006; 45 (1): 63-71
Aim of study (acc. to author)
magnetic field of a single pulse increased rapidly during the first 100 µs to a maximum and exponentially decreased afterwards within 1 ms. The time between two pulses was about 5 s. The frequency of a single pulse was estimated to be 12.4 kHz.
coil each with 50 mm diameter with a hole diameter of 10 mm
coil was fixed with the front of the coil in upside position. 35 mm Petri dishes were placed on top of the double coil and shielded against heat and vibrations with a 2 mm thick plate of plastic foam. Sham exposed dishes were placed in the same room but outside the influence of the coil.
sham exposure was conducted.
The dishes were
exposed to non- homogeneous MF. The MF and EF varied from +85% to -85% and 15 to 100%, respectively if the dishes were positioned in the middle position between the two turns and from 50 to 100% and 0 to 50%, respectively if positioned in the middle of each turn. The dishes were exposed in the middle of the coil, on the left side on the coil with the north magnetic direction, or on the right side of the coil with south magnetic direction.
