Abstract
A comparative analysis of changes in ultrastructure of neuro-muscular synapses of three types has been studied in the rat diaphragmal muscle at an acute poisoning with chlorophos. A high stability to the damaging action of chlorophos in white muscle fibers has been revealed in comparison with other types. The most essential changes of the ultrastructure have taken place in slow intermediate fibers. These differences are evidently connected with certain peculiarities in morphofunctional organization of calcium-sequestring ++ components of three types of muscle fibers (sarcotubular system, mitochondria) and presence of parvalbulin.
