More and more attention is paid to the effect of cations on living protoplasm. It was proved by Loeb that quantitative ratio of one of divalent cations has a great influence on excitability of living tissue (Loeb's coefficient), - increase of the former leads to excitation, and of the latter - to suppression of cell function. The former include Na, K, NH4, and the latter include Ca and Mg. What is applicable to a muscle, a nerve, may also be applicable when testing a whole organ. Particularly on the stomach, this effect of cations was tested by Pravdich-Neminsky with respect to changes in its motor function.
