[Neurotrophic control of the ionic regulation mechanisms for intracellular water content in muscle fibers of mammals].

The volume change of the muscle fibres in the hypertonic medium begins with cell shrinkage. Later the cell volume increases up to the normal level because of the furosemide-sensitive CL(-)-influx activation. The property of the Cl(-)-influx to be activated in the hypertonic medium is abolished after denervation. That causes a loss of the ability of muscle fibres to restore their cell volume in the hypertonic medium.
