|Exposure duration||4 h/d for 5 days|
|Setup||mice in individual plastic containers (6 cm x 6 cm x 7 cm) placed in foamed polystyrene frames in a 5 x 5 array which was placed in the chamber; sides of anechoic chamber lined with high-power absorbing material, floor had pyramidal absorbers|
|Sham exposure||A sham exposure was conducted.|
Survival of the sham-exposed mice increased as ambient temperature increased from 19°C to 34°C. At ambient temperatures at or above 37°C the heat induced in the body exceeded the thermoregulatory capacity of the mice and deaths from hyperthermia occurred.
Survival of the microwave-exposed mice was significantly greater than survival of the sham-exposed mice (approximately 20%) at each ambient temperature below 34°C.
Based on an analysis of the data it appears that the hyperthermia induced by microwave exposure may be more effective in increasing survival in infected mice than hyperthermia produced by conventional methods. Microwave irradiation may be beneficial to infected mice at low and moderate ambient temperatures, but it is detrimental when combined with high ambient temperatures.
