[The effect of cardiac glycosides and electrolytes on cell membrane sodium, potassium-adenosine triphosphatase].

A brief summary is given of the structure of the cell membrane and the enzyme system which actively transports Na+ and K+ ions across it. The function of different ions in this process is discussed as well as the effect of cardiac glycosides on ion transport. The utilization of electrolytes to combat cardiac glycoside poisoning and an indirect method for demonstrating the presence of cardiac glycosides in the organs of ruminants, suspected of being poisoned by these toxins, is described.
