[Accumulation of calcium ions in myocardial sarcoplasmic reticulum of restrained rats exposed to the pulsed electromagnetic field].

Alteration in the velocity of Ca++ accumulation was investigated in myocardial homogenates from restrained rats which were chronically (1 and 2 months) exposed to the impulse electromagnetic field with frequency 1 Hz and magnetic induction 6-24 mT. The fall of the studied variable by 33% was observed in a month while restoration of the velocity of Ca++ transport was shown after two months of exposure. The results are discussed in terms of the organism adaptation to physico-chemical and physiological impacts.
