[Space of initial distribution of transferrin labeled with indium 113m (author's transl)].

The over-estimate of plasma volume noted at the time of the substitution of iodine 131 labeled human serum albumin by indium 113m transferrin, probably results from a defective fastening of the radionucleide on the binding protein and not at all from a particular behavior of this last one as it has often been admitted.

Treatment of malignant gliomas and brain metastases in adults with a combination of adriamycin, VM 26, and CCNU. Results of a phase II trail.

Forty-three patients with inoperable or recurring malignant gliomas, and 30 patients with multiple recurring brain metastases were treated with a combination of Adriamycin (45 mg/m2) and 4-dimethyl-epipodophyllotoxin D-thenylidene (VM 26) (60 mg/m2 for 2 days) with 1-(2-chloroethyl)-3-cyclohexyl-1-nitrosourea (CCNU) (60 mg/m2 for 2 days). These cycles of treatment were repeated as soon as the hematologic restoration was complete. The treatment was well tolerated and the clinical condition of 31 of 43 glioblastoma patients improved during the 2 months after the beginning of the treatment.

[Combination chemotherapy in the treatment of polymetastic breast cancer. Comparison of therapeutic effects of 2 methods of sequential drug administration. Role of adriamycin in these combinations].

One thousand and twenty four patients with disseminated breast cancer were submitted to combination chemotherapy. Fifty one patients (group I) were sequentially given VCR, CPM and 5 FU, and seventy three patients (group II) were given ADM, VCR, CPM and 5 FU. The general and haematological tolerance was good and comparable in the both groups of patients: we observed only two severe infectious complications.

[Trial treatment of glioblastomas in adults and cerebral metastais by adriamycin, VM 26 and CCNU combination. Result of a type II trial].

Forty-three patients with inoperable and/or recurring malignant gliomas, and 30 patients with multiple recurring brain metastases were treated with a combination of adriamycine (45 mg/m2) and 4-dimethyl-epipodophyllotoxin D-thenylidene (VM 26) (60 mg/m2 for 2 days) with 1-(2-chloroethyl) -3-cyclohexyl-1-nitroso-urea (CCNU) (60 mg/m2 for two days). These cycles of treatment were repeated as soon as the hematological restoration was complete. The treatment was well tolerated and the clinical condition of 31 out of 43 glioblastoma patients improved during the two months after the beginning of the treatment.

[The action of the polypeptide placental hormones HCG and HCS on the blastic changes of lymphocytes in mixed cultures].

The present work studies the effect of the placental hormones HCG and HCS on cellular immunity in vitro. These two hormones used in identical or greater concentrations than found in circulating blood inhibit lymphoblastic changes in mixed cultures of lymphocytes. It is possible that HCG and HCS have the same inhibiting effect in vivo on immunity by cellular mediation in the pregnant woman.

[Estimate of coronary blood flow by simple fixation measurement of 86Rb on the cardiac muscle (author's transl)].

The method for measuring coronary blood flow, which is described here, is based on the estimate, by external detection, of the quantity of 86Rb fastened on the cardiac muscle about ten minutes after the injection. The discussion which follows after this report, shows that the use of such a late time for the measurements does not contradict the fondamental hypothesis but allows to work in perfect technical conditions. The results obtained,widely superposable to those which have been published until to-day, prove a posteriori the availability of the method.

[Error introduced in the radiocardiographic measurement of right volume by the non linearity of the detector in high count rates (author's transl)].

The short life tracers permit the use of high activities and so allow to follow with a good statistic accuracy fast phenomenons such as the different phases of cardiac revolution. However, this advantage may be quickly limited by the dead-time of the detection unit used. It results from this, in high activities, a non linear response which introduces non negligible errors which we have calculated and verifies thanks to experience in the measurement of right ventricular volumes.

[Chemotherapeutic combinations of mutually potentiating drugs. 2-Application to the treatment of bronchial cancers].

16 patients suffering from primary bronchial tumours which had recurred after surgery and/or radiotherapy and with spread involving at least one visceral or lymphatic metastasis received chemotherapy consisting of the administration of vincristine followed by a combination of CCNU and 5-fluorouracil. Each cycle of treatment lasted 6 days and was restarted only after an interval of 30 days on average, this being necessary for haematological recovery. With the doses of CCNU used, thrombocytopaenia occurred only during the fifth cycle of treatment and made it necessary to increase the interval between subsequent courses to five weeks.

[Chemotherapeutic combinations of mutually potentializing drugs. 1-Application to the treatment of breast cancers].

27 patients suffering from disseminated carcinoma of the breast with at least two visceral metastases, and two had become resistant to conventional chemotherpy and hormones, received a combination of, in the present trial, vincristine followed by cyclophosphamide with 5-fluoro-uracil. Chemotherapy was administered intermittently: each cycle of treatment lasted 6 days and was followed by a period without treatment of 25 days. Haematological tolerance was satisfactory.
