[The "anomalous" relationship between the concentration of potassium in the medium and the membrane potential of muscle fibers with a decreased intracellular potassium concentration. I. Movement of potassium, accompanying ions and water].
A study was made of the electrogenesis on (Na+C1)-free muscles in potassiumsulfate media, with the membrane potential not corresponding to Ek. It was found that the potassium content in these muscles may change: at 2.5 mM external potassium, the internal potassium content decreases, whereas at 75 mM it increases. Undoubtedly, some other ions (phosphates?) apart from K+ do penetrate the muscle membrane. The evidence obtained disprove a previous idea that under the condition described it is potassium alone which is involved in potential genesis.
