Abstract : The authors results after histochemical changes in the inner ear of guinea pigs exposed to continuous sound: Under the influence of sounds the following changes took place in the inner ear: (a) A reduction in the amount of glycogen grains in the nerve and hair cells. (b) A reduction in the amount of ribonucleic acid in the protoplasm of the nerve cells. (c) Changes in the size of cell nuclei and in the position of deoxyribonucleic acid, especially in the exterior hair cells. (d) Reduction in the activity of alkaline phosphatase. (e) Reduction in the amount of acid mucopolysaccharides in the cells of connective tissue. (Author)
