|Setup||48 cm x 27 cm x 15 cm ventilated plastic cage placed inside a temperature-controlled anechoic chamber lined with RF absorbing material; microwave oven connected to horn antenna; aperture of horn antenna facing the cage|
|Sham exposure||A sham exposure was conducted.|
A significant increase was observed in different parameters of comet assay (e.g. comet head length, tail length) in exposed brain cells. An analysis of antioxidant enzymes glutathione peroxidase and superoxide dismutase showed a decrease in enzyme activities under exposure while an increase in catalase enzyme activity was found. A significant decrease in histone kinase enzyme activity was also recorded in the exposed group as compared to the sham exposed ones.
The authors conclude that the chronic exposure to 2.45 GHz microwaves may cause a significant damage to the brain, which may be an indication of possible tumour promotion.
