title: [Calcium utilization in the neuromuscular junction after acetylcholin treatment (author's transl)].
abstract: In the site of the myoneural junction a liberation of Ca++ ions, which is similar to that described previously after an electric stimulation or use of cholinesterase inhibitor, can be revealed by histochemical methods (heavy metal substitution, tetracycline fluorescence technique and glyoxal-bis-(2-hydroxyanil) complex formation) using repeated acetylcholine and SCh administration. The possible aspecific reaction due to the presence of Mg++ ions can be excluded by means of the glyoxal-bis(2-hydroxyanil) method. It can be suggested that there is a correlation between the liberation of Ca++ ions an the function dependent mitochondrial energetic processes.
