Mitomycin C, 20 mg/m2 day 1, and vinblastine, 0.15 mg/m2 days 1 and 21, were administered intravenously to 31 patients with refractory previously treated advanced breast cancer. Courses were repeated every six to eight weeks when adequate hematologic recovery permitted. Thirty of the 31 patients were evaluable; one had a complete response and 11 had a(More)
Beta-2-microglobulin determinations in cerebrospinal fluid (CSF) of patients with leukemia, lymphoma, and oat cell carcinoma were performed to evaluate the utility of this test in early detection of metastasis to the central nervous system (CNS). In the presence of CNS disease, significantly higher levels (P less than 0.001) were found than in normals or(More)
A method is described for measurement of 5-hydroxytryptamine (5-HT) and 5-hydroxyindole acetic acid (5-HIAA) in cerebrospinal fluid. 5-HT and 5-HIAA are isolated from columns of Biorex BR-70 and Sephadex G-10 with recoveries of 85 and 89% respectively. The indoles are quantitated by fluorometric measurement of the ortho-phthaldialdehyde derivatives in(More)
Because of evidence suggesting that volatile anesthetics interfere with platelet aggregation in vitro, platelet function was investigated in patients exposed to combinations of nitrous oxide, halothane, and enflurane during brief surgical procedures. In 12 patients undergoing elective operations, blood was sampled before anesthesia, after induction but(More)
To assess the effects of dexamethasone on platelet function, aggregation studies were performed on nine healthy adults before and after ingestion of a single dose of dexamethasone 10 mg, and on six patients receiving daily dexamethasone. Bleeding times were done on 14 volunteers before and after a similar drug dose. Platelet aggregation by ADP, epinephrine(More)
The spatial concentration and size distribution for particles measured by the asteroid/meteoroid detector on Pioneer 10 between 2 and 3.5 astronomical units are presented. The size distribution is from about 35 micrometers to 10 centimeters. The exponent of the size dependence varies from approximately -1.7 for the smallest to approximately -3.0 for the(More)
BCG immunotherapy often has severe complications in cancer patients despite lack of toxicity in the immunocompetent individual. MER, a cell wall fraction of BCG, has been reported to cause immunopotentiation similar to that of BCG without equivalent toxicity. Recently, animal models have been reported to develop MER complications, especially disseminated(More)
