Abstract

A lectin histochemistry study was performed in the supraglottic and subglottic regions of 10 hamsters. The submucosal glands were observed by light microscopy. The supraglottic submucosal glands presented numerous mucous tubules but on the other hand, the subglottic submucosal glands had serous tubules which finished at the distal portion in serous acini. The results suggest that the distribution of fucosylatedmucin and serum-type glycloproteins between the supra- and subglottic submucosal glands suggest a different viscosity and function of the mucus.
