Effect of 900 MHz radiofrequency electromagnetic field exposure onserum and testicular tissue antioxidant enzymes of rat

摘要

Potential damage due to cell phones are mostly focused on headand reproductive organs. Effects of 900 MHz electromagnetic field (EMF) exposure on ratserum and testes antioxidant enzyme levels are described. Groups of 5 rats each were exposedfor 1h(STE), 2h(MTE), and 4h(LTE) for 30 consecutive days to EMF with average power densityof 86mW/cm2 for 30 consecutive days. One group were sham controls. Blood sampling wasperformed at days 0 and 30, but testicular sampling was performed only on day 30. Serum andtesticular superoxide dismutase (SOD), glutathione peroxidase (GPx) and glutathione reductase(GRx) were measured. After 30 days exposure, serum SOD or GPx activity declined (P<0.05) inLTE or MTE rats compared with other or sham groups. In testicular tissue, GPx decreased inMTE (259.93±61.77 U/mg) and LTE (235.54±56.90 U/mg) groups compared with controls(677.17±194.96 U/mg) (P<0.05). Results should be interpreted with caution due to small (n=5)sampling values.
