Immunohistochemical Examination of S-100 Protein and Substance P in the Inner Ear of the Rat

Abstract
S-100 protein and substance P in the inner ear of the rats on decalcified specimens was investigated immunohistochemically. Immunoreactivity of S-100 protein and substance P was found in various parts of inner ear tissues. These results suggest the possibility of immunohistochemical study of decalcified and paraffinized inner ear tissues.
