[Investigation of immunoglobulin presence and localisation in epithelial lining of radicular cyst walls by ABC immunoperoxidase technique].

Immunoglobulin classes A, G and M in the epithelial lining of radicular cysts are analysed by a new method: ABC immunoperoxidase technique. The obtained results show a high degree of all immunoglobulin classes present in the cyst walls, as well as in the epithelial lining. The findings suggest the important role of immunoglobulin in the processes occurring in the radicular cyst walls.
