Abstract:
:In this study, the efficacy of bactericidal/permeability-increasing protein (BPI) was assessed in a rat model of chronic otitis media with effusion. BPI injection prevented disturbance of the mucociliary clearance system of the middle ear. Hence, it is postulated that BPI can be a new therapy for chronic otitis media with effusion.
