To investigate the effects of exposure to extremely low frequency magnetic fields on the enzyme activities of the adenosine deaminase and xanthine oxidase.
The enzyme activity was determined at different time points after exposure, from 0 to 250 minutes.
Exposure duration: continuous for up to 250 min
|Exposure duration||continuous for up to 250 min|
|Setup||pair of round Helmholtz coils with a radius of 17.5 cm, placed 17.5 cm apart; samples placed in the center of the coil system|
|magnetic flux density||5.8 mT||-||calculated||-||-|
The enzyme activity of the adenosine deaminase decreased over time in exposed and unexposed samples. However, in magnetic field exposed samples of adenosine deaminase, the curve of the enzyme solution showed a significant steeper decline compared to samples of the control group.
The enzyme activity of the xanthine oxidase was significantly increased in exposed samples compared to unexposed samples. Most of this increase occurred during the first few seconds.
The data indicate that extremely low frequency magnetic fields can affect enzymatic systems.
