[Eosinophils in nasal mucosa of patients with nasal polyps: preliminary histochemical study].

Glycoproteins and glycolipids play an important role in cellular biological specificity. The use of lectins as histochemical probes may be useful in studying the nasal mucosa. Eosinophils are a common finding in the nasal mucosa of patients with nasal polyposis. Histocytochemistry of eosinophils in the nasal mucosa of such patients revealed reactivity to all lectins used in this study except LTA. This suggests that alpha-L-fucose was not present in the eosinophils of the nasal mucosa of patients with nasal polyposis and asthma.
