Model		2450 MHz (CW) exposure to Syrian hamsters and effects on immune parameters
Details		Syrian hamsters were immunized with vaccinia virus and exposed to 2450 MHz (CW) microwaves in an anechoic chamber for either 1 hour at 25 mW/cm2 or for 1 hr/day for 5 days at 15 mW/cm2. Immunizations were performed either 4 days prior to acute (single day/25 mW/cm2) exposure or immediately after the 2nd daily exposure for the 5 day exposure (15 mW/cm2). In acutely exposed animals, at 4 and 6 hr following acute exposure spleen cell NK activity (as measured by 51Cr-release) was significantly reduced. Circulating NK activity was also reduced at 1 hour following acute exposure, and returned to normal by 8 hours. The reduction in NK activity was paralleled by marked lymphopenia accompanied by neutrophilia. A transient elevation of serum glucosteroid levels was also observed. Acute MW exposure did, however, significantly elevate core body temperature by ~ 3 degrees C, and returned to normal by 60 minutes after termination.
