    Notizen: Summary The relationship between antigen levels in middle ear effusions (MEE) and the degree of middle ear inflammation was studied in an antigen-induced otitis media model, using chinchillas sensitized with human serum albumin (HSA). The degree of middle ear inflammation was evaluated by both tympanometric analysis, and cytological and biochemical analyses of the MEE. Middle ear inflammation develops after HSA challenge with a remarkable decrease in HSA levels in the MEE. This inflammation persists even when HSA levels are no longer detectable in the MEE. These findings show that local challenges with an antigen induce a certain degree of middle ear inflammation, which continues even after complete elimination of the antigen from the middle ear through an immunological defense mechanism.

    Notizen: Summary We have measured interleukin-1α (IL-1α) and β levels in nasal polyps (NP) from patients with chronic sinusitis (CS) in order to determine their significance in the pathogenesis of NP. NP in ten cases (five male and five female; age range, 17–63 years) were removed to separate mononuclear (M) and polymorphonuclear (PMN) fractions through Ficoll-Paque separation media. ELISA measurements of the M fraction showed that the mean value of IL-1β was 17.8 pg/mI per gram, which was significantly higher than that of IL-1α (7.04 pg/ml per gram, P〈0.01, Wilcoxon test). In the PMN fraction, the mean value of IL-1α was 8.79 pg/ml per gram and that of IL-β was 7.85 pg/ml per gram, which was not significantly different. Mononuclear leukocytes, particularly activated monocytes, seem to be a major source of IL-1 in the NP taken from patients with CS.

    Notizen: Summary The pathogenesis of immune complex (IC)-induced otitis media in the chinchilla was studied through cytological and biochemical analyses of middle ear fluid (MEF) recovered after instillation of premade IC. The number to total leukocytes was 3.03±2.13×106/cm3, and mainly involved neutrophils (72.3%) and macrophages (22.7%). The mean value of total protein, α1-antitrypsin (α1-AT) and α2-macroglobulin (α2-M) was 27.1mg/ml, 189.5 and 75.2mg/dl. The number of leukocytes had a significant correlation with the levels of total protein, α1-AT and α2-M (P〈0.01). The inflammatory reaction induced by premade IC is characterized by an increased vascular leakage and an infiltration of leukocytes into the locus. The percentage of macrophages in the total leukocytes was larger in IC-induced otitis media than that in antigen-induced otitis media. These findings suggest that cellular events in the early stage of IC-induced otitis media may be different from antigen-induced otitis media.
