The effect of Ammonium on the potassium content of unstriated muscle and its relation to the contraction produced on withdrawal of chemical substances from around the muscle
(1) In frog stomach muscle, ammonium enters the cells and replaces potassium; this is associated with the ammonium withdrawal contraction having the properties of the A.C. contraction.(2) In dog muscle there is no significant difference between the potassium contents of muscles soaked in normal saline, and in ammonium-rich saline respectively; with this is probably associated the absence in dog muscle of the ammonium withdrawal contraction having the properties of the A.C. contraction.(3) Ammonium causes greater replacement of potassium than the tetra-ammonium salts; with this is probably associated the fact that the latter do not produce a contraction on withdrawal, similar to that of ammonium in frog mus
