[In vitro cytotoxicity in the immunological study of human glioblastomas].

An immunological study about the lymphocytes of nineteen patients affected by glioblastoma has been executed by using CML and ADCC tests. Eleven healthy subjects and nine ones affected by bladder carcinoma have been studied for control. The CML test has demonstrated an increase of citotoxic activity of lymphocytes in the totality of the patients affected by glioblastoma (37,09 +/- 3,67)% versus (4,00 +/- 1,78)% of controls. The ADCC test has demonstrated diminution of citotoxic activity of lymphocytes of the patients affected by glioblastoma in comparison with controls (20,57 +/- 9,77)% versus (29,18 +/- 6,67)% of the healthy controls versus (27,66 +/- 8,51)% of bearers of bladder carcinomas.
