Effects of GSM modulated radio-frequency electromagnetic radiation on permeability of blood-brain barrier in male & female rats
This rat study examined whether pulse-modulated 900 MHz and 1800 MHz RF exposure affects blood-brain barrier permeability using Evans blue dye. The abstract reports increased permeability in male rats at both frequencies (stronger at 1800 MHz) and in female rats at 900 MHz but not at 1800 MHz. The authors suggest mobile-phone-like RF exposure could increase blood-brain barrier permeability under non-thermal conditions, while noting that further mechanistic studies are needed.
Key points
- Animal experiment in young adult male and female Wistar albino rats with six groups.
- Exposure involved pulse-modulated RF at 900 MHz and 1800 MHz for 20 minutes.
- Outcome was blood-brain barrier permeability assessed by whole-brain Evans blue dye content after intravenous injection.
- Male rats showed higher dye content after both 900 MHz and 1800 MHz exposure versus controls (reported p<0.01).
- In males, 1800 MHz exposure was reported as more effective than 900 MHz (reported p<0.01).
- Female rats showed increased dye content after 900 MHz exposure, while 1800 MHz did not differ from control (reported p>0.01).
- Authors propose sex-related physiological differences may contribute to differing responses.
- Exposure characterization details such as SAR were not provided in the abstract.
