[Effects of centimeter waves on the immune system of mice in endotoxic shock].
The effects of centimeter waves (8.15-18 GHz, 1 microW/cm2, 1 h daily for 10 days; MW) on the production of the tumor necrosis factor alpha, interleukin-lalpha, interleukin-1beta, interleukin-2, and the expression of interleukin-6, interleukin-10, interferon-gamma, nitric oxide and HSP27, HSP72 and HSP90alpha in mice irradiated before or after LPS injection were studied. An acute endotoxic model was produced by a single LPS injection. The effects of microwaves on nitric oxide, interleukin-6, tumor necrosis factor-alpha, and interferon-gamma were dependent on the functional status of exposed animals. Thus, an exposure of healthy mice to microwaves for 10 days was followed by a decrease in nitric oxide and interferon-gamma production, and an increase in the production of the tumor necrosis factor-alpha and interleukin-6. On the contrary, an exposure to MW before intoxication resulted in an increase in the synthesis of nitric oxide and interferon-gamma as well as a decrease in the concentration of the tumor necrosis factor-alpha and interleukin-6 in blood of mice in endotoxic shock. When microwave exposure was used after LPS injection, it did not provide any protective effect, and preliminary irradiation enhanced the resistance of the organism to endotoxic shock.
