15 صفحه اولL-asparagine depletion and L-asparaginase activity in children with acute lymphoblastic leukemia receiving i.m. or i.v. Erwinia C. or E. coli L-asparaginase as first exposure.
PURPOSE The present study was aimed at investigating L-asparaginase (L-ASE) activity (in plasma) and L-asparagine (L-ASN) depletion (in plasma and CSF) in children with newly diagnosed acute lymphoblastic leukemia (ALL) exposed for the first time to different L-ASE products. PATIENTS AND METHODS During the induction treatment of the AIEOP ALL 95 study, 62 patients were treated with either Erw...
متن کاملGuinea pig serum L-asparaginase. Properties, purification, and application to determination of asparagine in biological samples.
After the first isolation of asparagine in 1806 by Vauquelin and Robiquet (l), there were numerous studies of its properties and physiological significance (2-4). Piria (5) in 1848 was probably the first to adduce evidence for a physiological role of asparagine during the life cycle of plants, and also to observe its transformation or metabolism by yeast. However, it was not until approximately...
متن کاملL-Asparagine synthetase in serum as a marker for neoplasia.
L-Asparagine synthetase appears in serum approximately 7 days after the s.c. implantation of 1 X 10(5) cells of Leukemia 5178Y/AR (resistant to L-asparaginase) and increases in activity as the neoplasm grows and metastasizes. The principal source of the enzyme is the primary tumor. After intravranial inoculation of tumor, the rate of leakage of the enzyme is more pronounced than when the subcut...
