Blood-forming system in rats after whole-body microwave exposure ; Reference to the lymphocytes

The influence of 2.45 GHz microwave (RF/MW) irradiation on blood-forming cells after whole body irradiation of rats was investigated. This study describes cell response as assessed by determination of the bone marrow nuclear cells, in addition to the peripheral blood white cells according to a number and type, with particular reference to the lymphocytes. According to the established procedure, rats were divided into four subgroups that were anticipated for irradiation. Concurrent the sham-exposed and matched controls were included into the study. The exposures were conducted with a field power density of 5-10 mW/cm2, and whole-body average specific absorption rate (SAR) of 1-2 W/kg. Four experimental subgroups were irradiated 2, 8, 15 or 30 days, for two hours a day, seven days a week. The cell response was assessed by number and type of the bone marrow nuclear cells and peripheral blood white cells using standard laboratory methods. Significant decrease in lymphoblast count was obtained at 15 and 30th experimental day (p<0.05), whereas other examined parameters did not significantly differed in comparison to the sham-exposed controls. The findings point out at stress response in blood-forming system in rats after selected microwave exposure which could be considered rather as sign of adaptation than malfunction
