The Numerical Density of Immunoglobulin Producing Cells in Diseased Palatine Tonsils

The number of immunoglobulin (Ig)-producing cells per mm of tonsillar tissue, i.e., numerical density and their distribution in tonsils from patients with idiophatic tonsillar hyperplasia (ITH), chronic hyperplastic tonsillitis (CHT) and recurrent tonsillitis (RT) were analysed. The numerical density was determined on serial sections of paraffin embedded tonsillar tissue stained by peroxidase-antiperoxidase (PAP) method. The number of IgAand IgGproducing cells was significantly decreased in ITH, increased in RT, and unchanged in CHT in comparison with control group. In ITH and CHT numerical density of IgM -producing cells was increased whereas no difference in RT was registered. The obtained results could provide information relevant to the immunological competence of diseased tonsils.
