Exposing human blood platelets to a 50 Hz magnetic field for 15 minutes was associated with higher free radical levels and lower superoxide dismutase activity, regardless of field shape.

Plain English Summary

Summary written for general audiences

Researchers exposed human blood platelet suspensions for 15 minutes to a 50 Hz magnetic field of different shapes at a flux density of 10 mT. The study measured catalase and superoxide dismutase activity, malondialdehyde concentration, and free radical generation in human blood platelets. Free radicals, malondialdehyde, and catalase all showed increased values compared with the initial level regardless of field shape, while superoxide dismutase activity was lower than at the onset of the experiment.

Why This Matters

The field shape was varied across conditions, yet increases in free radicals, malondialdehyde, and catalase were seen regardless of which shape was used. The authors suggested that the oxidative stress resulting from exposure to the 50 Hz magnetic field of 10 mT induction may produce a number of adverse effects within the cell and may lead to systemic disturbances in the human body.
