Acute leukemia in idiopathic sideroblastic anemia: response to combination chemotherapy.

Three patients with idiopathic sideroblastic anemia of variable duration developed acute leukemia. In two the leukemia was morphologically and histochemically myeloblastic, in one lymphoblastic. With combination chemotherapy remission was achieved in all three.

Effects of selenium administration on erythrocyte and blood plasma glutathione peroxidase activity in goats.

The activity of glutathione peroxidase (GSH-Px, E.G. 1.

Effects of different anticoagulants on determination of erythrocyte glutathione peroxidase.

Glutathione peroxidase (GSH-Px) was determined in whole blood from cows, goats and horses using cumenehydroperoxide as substrate. Heparin was found to be the most suitable anticoagulant. The highest activities of GSH-Px were found with high concentrations of heparin in the blood samples (1000 and 1250 IU/ml of blood).

Doxorubicin and ifosfamide combination chemotherapy in previously treated acute leukemia in adults: a Southwest Oncology Group pilot study.

The Southwest Oncology Group did a limited institutional pilot study of the combination of doxorubicin and ifosfamide in the treatment of previously treated adult patients with acute leukemia. Thirty-four patients received one or two courses of the combination. All patients had received prior chemotherapy and 32 had received prior anthracycline chemotherapy.

Autoimmune thrombocytopenia and peripheral neuropathy heralding Hodgkin's disease.

A patient with an autoimmune thrombocytopenic syndrome was treated unsuccessfully with splenectomy. Treatment with corticosteroids and 6-mercaptopurine was partially successful, but the patient developed peripheral neuropathy and over signs of Hodgkin's disease. The latter reponded completely to radiation therapy, but the thrombocytopenia was not reversed until combination chemotherapy was given.
