Objective: To evaluate the expression of eosinophil major basic protein (MBP) in chronic rhinosinusitis (CRS) and discuss the role of MBP in the pathogenesis in CRS.
Method: Thirty-eight nasal mucus obtained from CRS patients were used to detect the expression of MBP by Elisa assay. Thirty nasal mucus samples from health people were used as control.
Result: The expression of MBP of nasal mucus obtained from CRS patients was obviously higher than that of nasal mucus obtained from control. There was significant statistical difference (P < 0.01).
Conclusion: MBP was involved in the formation of CRS.
