[Histochemical studies of the denervated posterior cricoarytenoid muscle following direct long-term stimulation in an animal experiment].

Histochemical evaluation (ATP-ase, NADH-Diaphorase, PAS) of the posterior cricoarytenoid muscle of the sheep was performed after long-term direct electrical stimulation to determine the changes of fibre type ratio and muscle metabolism. For comparison, histochemical results of a normal and a denervated, not stimulated posticus muscle are described.
