[Comparative properties and histochemical-type composition of skeletal muscles in various forms of experimental neuromuscular pathology].

The authors studied the characteristics of isometric contraction in in vivo experiments and the histochemical typical composition of muscles in different forms of experimental impairments of innervation simulating clinical pathology. The results demonstrate that in different forms of neuromuscular pathology there is a general tendency toward changes in the histochemical composition of muscles whereas alterations of contractile parameters of these muscles are fairly specific for each type of investigated disorder.
