Vital Staining of Nerve Structures with Fluorescent Dyes and Optical Determination of Acetylcholine in the Somatic Muscle of the Earthworm Lumbricus terrestris

  • Published:
Bulletin of Experimental Biology and Medicine Aims and scope

Experiments with fluorescent dyes showed that high concentrations of K+ ions in the medium depolarize the membrane and enhance exo-endocytosis in nerve structures, which is accompanied by an increase in acetylcholine concentration in the somatic muscle of earthworm. In the presence of BAPTA and without Ca2+ exo-endocytosis is sharply decelerated, the level of acetylcholine in the muscle decreases, but remains relatively high.
