Biomarkers inducing changes due to microwave exposure effect on rat brain

Animals were exposed for 2 h a day for 45 days at 0.21 mW/cm² power density SAR (0.038 W/Kg). After exposure, pineal gland and whole brain tissues were separated for the study of melatonin, creatine kinase and caspase 3. Result showed a significant decrease (P<;0.05) in melatonin level in the exposed group as compared with sham-exposed. A significant increase (P<;0.05) in creatine kinase and caspase 3 was also observed in exposed group of whole brain as compared with sham exposed. The study concludes that the chronic exposure to these radiations may be an indication of possible tumor promotion.
