Emission Intensity and Time Dependency of Influence of Irradiation by Waves Emitted from 65kHz Toroidal Coils on Forced Swimming Behavior of Mice

Mice were irradiated by an ETC (emission from a toroidal coil system) wave field, and the difference in physical stamina between irradiated (3mA, 5mA) and control (unirradiated) groups was examined. The change of the feed quantity caused a clear change in the rectal temperature of the mice on the condition that the quantity was insufficient. The immobile time showed a clear tendency to increase as the rectal temperature fell, and reached the maximal value on the eleventh day, when the rectal temperature was the lowest. The 5-minute irradiation in this study did not cause any significant difference among the mean values of the immobile time of the three groups. These results in addition to those of our previous report led to a conclusion that the irradiation time necessary to improve the stamina of physically weakened mice was at least ten minutes. Current (hence emission intensity) dependency of the influence of irradiation was not clarified, because the irradiation time was not long enough. ETC irradiation raised the rectal temperature of live mice, but did not cause any change in that of a dead mouse. This meant that it affected the autonomic nervous system of the mice.
