Quantitation and Immunocytological Identification of lnterleukin-1 in Nasal Polyps from Patients with Chronic Sinusitis

Abstract
Immunoreactive interleukin-1 (IL-1) α and β levels in nasal polyp (NP) extracts were measured from 22 adult patients with chronic sinusitis (CS) in order to determine their significance in the pathogenesis of NP. The NP sample was separated into mononuclear and polymorphonuclear fractions. In the mononuclear fraction, the mean value of IL-1β was 21.5 pg/ml/g, which was significantly higher than that of IL-1α (8.4pg/ml/g, p
