Histochemical Demonstration of Oxidative Enzymes in Human Salivary Glands.

Recently, the salivary glands function from biochemical, physiological and histochemical standpoints have been rather highlighted. Many investigators have come to try a histochemical detection of enzymes participating in various metabolic pathway in the salivary glands of experimental animals and humans. The previous study of this series dealt with the histochemical demonstration of various hydrolytic enzymes and dehydrogenases in major salivary grands (KAWAKATSU et al. 1960 a, b, 1961 a, b, 1962 a-d). It covered a comparison of the presence of enzymes in the serous and mucous cells of animal salivary glands. It also refered to relations between the localization of oxidative enzymes and their mitochondrias deposition in the electron microsrope. The present experiments were a histochemical approach to the distribution of oxidative enzymes in human major salivary glands.
