Immunological investigations on tonsillar and peripheral blood lymphocytes after adeno-tonsillectomy. Possible suggestions for phenotypical and functional differences.

The phenotypical and functional aspects of tonsillar (TMNC) and peripheral blood mononuclear cells (PBMNC) obtained from 40 patients who had undergone adeno-tonsillectomy for different tonsillar diseases were investigated. TMNC and PBMC were separately tested at the time of surgery; then a further investigation on the peripheral blood lymphocytes was performed three months after surgery. The most interesting findings are presented and discussed with particular attention to their clinical implications.
