title: [Action of aureolic acid and dactinomycin group antibiotics on human brain tumors in culture].
abstract: The cytotoxic effect of antitumour antibiotics, such as dactinomycin, mithramycin, variamycin and olivomycin on the cells of the human brain tumours (multiform glyoblastoma, arachnoidendotelioma and astrocytoma) grown by the method of the primary plasmic culture was studied. Dactinomycin was superior to the antibiotics of the aureolic acid group in the rate and level of the cytotoxic effect on the tumour cells: 76 per cent of the above tumours were sensitive to dactinomycin, 56 per cent to mithramycin and 52 per cent to variamycin and olivomycin. Among the total number of the tumours sensitive to the drugs the number of the highly sensitive tumours amounted to 57.9 per cent for dactinomycin and 30.8--38.5 per cent for the antibiotics of the aureolic acid group. Definite differences in the efficiency of the antibiotics of the aureolic acid group with respect to different types of the brain tumours were observed.
