To clarify the biochemical difference between pediatric and adult middle ear effusions (MEEs), we analyzed the protein components from MEEs of 3 children and 3 adults by electrophoresis. High molecular protein components (280 and 265 kDa proteins), which contained in sera in the concentrations less than 2.5%, were not detected in MEEs even in trace amounts. Mucin was comprised about 30% of the total protein in mucous MEEs and the weight ratio of mucin to albumin in mucous MEEs was 2.69, but serous MEEs from adult patients did not contain mucin.
