title: Major basic protein, eosinophil cationic protein, and arylsulfatase in nasal secretions of patients with Japanese cedar pollinosis.
abstract: In 15 patients with Japanese cedar pollinosis and 10 healthy control subjects, levels of major basic protein (MBP), eosinophil cationic protein (ECP), and arylsulfatase B (As) in the nasal secretions were examined before and after challenge with Japanese cedar pollen extract. The MBP and ECP levels in the patients were significantly higher 30 min after challenge than those before challenge (P < 0.005). MBP and ECP levels after challenge were significantly higher in the nasal secretions of patients than in the controls (MBP: P < 0.01, ECP: P < 0.05). The level of As after challenge was significantly higher in the nasal secretions of patients than in the controls. These results suggest that eosinophils activate or modify the immediate, nasal allergic reaction and have a role in regulating immunological responses.
