A series of 41 nasal polyps (23 single and 18 massive) and 6 normal nasal mucosa specimens was glycohistochemically investigated. Five plant lectins were used, ie, the peanut agglutinin (PNA), the wheat germ agglutinin (WGA), the gorse seed agglutinin (UEA-I), the Maackia amurensis agglutinin (MAA), and the elderberry bark agglutinin (SNA). A neoglycoconjugate and 2 animal lectins (CL-14 and CL-16) were also used. Three quantitative features were calculated by means of computer-assisted microscopy: the percentage of tissue area specifically stained by the histochemical probe, the staining intensity, and the heterogeneity level of the staining distribution. The results show that with respect ...
