[Electrolyte content in the blood of animals and potassium ion transport in the erythrocytes under the action of a constant magnetic field].

The content of potassium and sodium ions in the blood and plasma of rats exposed to constant magnetic fileds (CMF) of 1000 and 4500 oersted for varying time was studied. The transport of potassium ions through membranes of red blood cells was examined in in bitro experiments using a CMF of 4500 oersted. An exposure of animals to a CMF of 1000 oersted for 1 and 24 hours did not produce significant changes in the potassium and sodium content in blood. An exposure of animals to a CMF of 4500 oersted induced certain changes in the electrolyte composition of the blood. During an hour exposure the most distinct changes were an increase in the potassium concentration in plasma and its decrease in blood. During a 3-hour exposure the most marked change was a decrease in the sodium content in blood. Repeated and prolonged chronic exposure did not bring about summation of the effects. The exposure did not influence the transport of potassium ions. The exposure did not affect the pH and hematokrit values of the blood.
