[The lack of the effect of a strong constant magnetic field on isolated membrane preparations of Na,K-dependent ATPase]. / Ob otsutstvii vliianiia sil'nogo postoiannogo magnitnogo polia na izolirovannye membrannye preparaty Na,K-zavisimoi ATFazy.

Effect of constant magnetic field (CMF) with induction 10 T on membrane preparations of Na,K-dependent ATPase of bovine brain (lipoproteid vesicules with 300-500 A diameter) were studied. No CMF effect on the activity of Na,K-dependent ATPase was observed under different experimental conditions (three temperature points 15, 20 and 37 degrees C and great variation of Na+,K+ concentrations ratio). CMF also produced no effect on the preparations of Na,K-dependent ATPase immobilized by adsorption on millipore filters.
