Exposure duration: continuous for 30 min
|Setup||pair of Helmholtz coils with a diameter of 10 cm and 220 turns of 0.8 mm gauge copper wire each; coils mounted on a plastic frame, 15 cm apart, parallel to the table, connected in series|
|Sham exposure||A sham exposure was conducted.|
|Additional info||isolated sciatic nerve fibers of the control group were located in bath and stimulated with 0.1- 0.5 ms, 0.05 V pulse|
|magnetic flux density||1 mT||-||measured and calculated||-||-|
The data showed that maximum amplitude and hyperpolarization time were significantly lower in the magnetic field exposure group than in the control group. However, conduction time, minimum amplitude, depolarization and repolarization times of the action potential were not different between control group and magnetic field group.
In conclusion, the 50 Hz magnetic field exposure caused a decrease in the maximum amplitude value and hyperpolarization time of the action potential in the rat nerve.
