Rats exposed to a 900-MHz EMF for one hour daily throughout adolescence had fewer hippocampal pyramidal neurons and showed oxidative stress changes.

Plain English Summary

Summary written for general audiences

Eighteen male Sprague Dawley rats aged 21 days were randomly assigned to control, sham, and EMF groups. The EMF group received a 900-MHz field for one hour each day throughout adolescence while the sham group was placed in the same cage without exposure. The EMF-exposed rats had fewer pyramidal neurons, more pyknotic neurons, higher malondialdehyde and glutathione levels, and lower catalase levels than the other groups.

Why This Matters

All rats were sacrificed at 60 days of age and their brains were halved, with the left hemispheres used for biochemical assays and the right hemispheres for stereological and histopathological evaluation. The authors concluded that oxidative stress-related morphological damage and pyramidal neuron loss may occur after adolescent exposure to 900-MHz EMF.
