Glycoconjugates in cat, monkey and human nasal mucosa were studied histochemically. With PAS-AB and HID-AB methods, light microscopy showed much sulfomucin in the goblet cells lining the surface epithelium. Most of the mucous cells in the upper area of the human nasal mucosa were stained with HID and the deeper cells were stained with AB. A large amount of sulfomucin was found in the mucous cells in the cat nasal mucosa as compared with the monkey nasal mucosa. The glycoconjugates of serous cells seemed to be composed mostly of neutral glycoprotein.Electron microscopic cytochemistry of the monkey nasal mucosa showed secretory granules of glycoprotein could be classified by their PTS staining into four types in the serous cells and three types in the mucous cells. The cilia, microvili, apical plasmalemma and basolateral membranes of several cells were stained positively with the PTS method. The results of DI and HID methods were also demonstrated in this study.
