ABSTRACT
Metabolic parameters in rats were studied at various stages of repeated exposure to modulated low-intensity UHF radiation. The volume of O2 consumption and level of heat release were reduced by day 4 of intermittent irradiation and remained low over the next 2 days in the absence of a source for electromagnetic radiation. The amount of expired CO2 slightly increased over the first 3 sessions of irradiation, but significantly decreased in the recovery period on days 5 and 6. Changes in metabolic parameters were most significant on day 7 of the study. It was manifested in the decrease of O2 consumption, CO2 release, and intensity of heat exchange not only during irradiation, but also in the inter-exposure period. Electromagnetic radiation can induce a change of metabolic processes in mammals, which is most pronounced during repeated irradiation and persists even under physiological resting conditions.

To conduct electroencephalographic investigations of stationary and moving objects a small-sized 4-channel amplifier built with integrated microcircuits has been developed. Each channel includes a pre-amplifier, main amplifier, calibrator, high and low frequency filters and a power pack. The adoption of integrated microcircuits enables it to locate the pre-amplifiers directly on the object of investigations. The device is highly sensitive and secures a greater degree of noise-protection.
