Abstract
OBJECTIVE: To investigate the features of nasolacrimal duct MALT (mucosa-associated lymphoid tissue), and to explore the aetiology of chronic dacryocystitis. METHOD: The mucous of nasolacrimal duct, nasal cavity, pharyngeal and trachea of 20 rabbits were studied, and the lymphoid tissue and HEV of them were compared. RESULT: The number of lymphoid follicle and HEV in nasolacrimal duct epidermis were less than that in nasal cavity, pharyngeal and trachea (P<0.01). CONCLUSION: In normal condition the immune response of nasolacrimal duct membranae is lower than other mucosa of head-neck.
