Abstract:
The study was carried out in 50 male rats abdominally implanted with biotelemetric systems (BTS) or mock-up. The animals were provided with 12/12 light/dark schedule during 6-week experiment. The electromagnetic field (EMF) frequency was 455 kHz, magnetic induction near transducer was about 10(-2) mT. Circadian rhythm of the body temperature and locomotor activity was controlled in course of the experiment. The latter been finished, some tissues and the blood of the animals have been sampled to test corticosterone, testosterone, T3, T4 level in serum with radioimmunoassay and membrane permeability for Ca2+, Na+, K(+)-ATPase activity and charge changes in liver microsomes was detected. The probable ways of the EMF influence on whole body are discussed.
