Possible effects of RF EMR on contextual fear conditioning, hippocampal perivascular space, apoptosis and adrenal gland microarchitecture in rats
This animal study exposed male Wistar rats to 900 MHz RF-EMR from a mobile phone for 1 hour daily over four weeks and assessed behavior and tissue changes. The authors report altered contextual fear conditioning-related behavior in exposed rats. Histological assessments indicated apoptosis and enlarged perivascular space in the hippocampal CA3 region and apoptotic/inflammatory-like changes in the adrenal zona fasciculata, with no reported differences in adrenal medulla cytoarchitecture.
Key points
- Male Wistar rats were exposed to 900 MHz mobile phone RF-EMR for 1 hour per day for four weeks.
- Control, sham, and exposed groups underwent contextual fear conditioning testing on day 29.
- Exposed rats showed increased transitions between bright and dark compartments and decreased latency to enter the dark compartment.
- Marked apoptosis was reported in the hippocampal CA3 region in the exposed group.
- The hippocampal perivascular space was reported as significantly enlarged after exposure.
- The adrenal zona fasciculata showed apoptotic-like changes, lymphocytic infiltrates, and congested sinusoids in exposed rats.
- The adrenal medulla cytoarchitecture was reported as comparable across groups.
