Abstract Human tonsils act as filters at the begining of both respiratory and digestive systems They are known to be immunologically reactive lymphoid tissue which manifests specific antibody and Band T cell activity in response to a variety of antigens, carrying out the functions of humoral and cellular immunity. The tonsils contain many cells, committed to antibody formation which can be shown to contain immunoglobulins of the main classes: IqG, IgA and IgM. The palatine tonsils release their antibodies locally as well as in the general pool. The impact of the microbiological environment on the developing lymphoid tissues of the tonsils results in one of the most common surgical procedures in childhood, the subsequently so often misused. The question wether the removal of tons i Is and adeno ids. Adeno-tons i llectomy has such a popular operation, so widely used and removal of the tonsils might compromise the body defence microbes is the focus of a long-standing controversy. The humoral aspect of the tonsils is the most role of their immunological function and hence to change if they are involved in a chronic process or if they are surgically removed. |
