Abstract
For the purpose of tonsillar immunological response in respiratory infection, tonsils of thirty adult patients with acute pharyngitis were investigated by immunofluorescent staining method. The number of cells containing immunoglobulins agA, IgG and Secretory IgA) increased significantly 5 to 9 days after pharygeal pain. This result proved that tonsillar immunoglobulin producing cells responded to infection, and suggested a valuable immunological function.
