Biochemical, radiologic, ultrastructural, and genetic evaluation of iron overload in acute leukemia and iron-chelation therapy.
Iron overload in hereditary hemochromatosis and hematologic malignancy has unfavorable effects on morbidity. Herein, 53 children (age 108.4±58.3 mo, 25 girls and 28 boys) with acute myeloblastic and lymphoblastic leukemia, who received 4 different chemotherapy protocols, were evaluated for iron overload throughout chemotherapy. Iron overload arose: (1) before chemotherapy, which was dependent o...
متن کاملManganese-induced hydroxyl radical formation in rat striatum is not attenuated by dopamine depletion or iron chelation in vivo.
The present studies were aimed at investigating the possible roles of dopamine (DA) and iron in production of hydroxyl radicals (OH) in rat striatum after Mn2+ intoxication. For this purpose, DA depletions were assessed concomitant with in vivo 2,3- and 2,5-dihydroxybenzoic acid (DHBA) formation from the reaction of salicylate with OH, of which 2,3-DHBA is a nonenzymatic adduct. Following intra...
متن کاملIRON METABOLISM Iron overload and chelation
Iron is one of the most common elements in nature. As a transition metal it is very efficient in electron transport and redox reactions. The proteins and enzymes in which iron is an essential component play a key role in respiration, energy production, detoxification of harmful oxygen species and cell replication. Despite the abundance of iron in nature, the solubility of its stable ferric form...
متن کاملIron chelation and multiple sclerosis
Histochemical and MRI studies have demonstrated that MS (multiple sclerosis) patients have abnormal deposition of iron in both gray and white matter structures. Data is emerging indicating that this iron could partake in pathogenesis by various mechanisms, e.g., promoting the production of reactive oxygen species and enhancing the production of proinflammatory cytokines. Iron chelation therapy ...
متن کاملTransfusion Iron Chelation Therapy
As a unique electron donor and acceptor, iron is an essential element in most biological systems. However, its chemical reactivity can result in iron potentially becoming a toxin when present in excessive quantities; accordingly, total body iron must be tightly regulated. As humans have no physiological mechanism for the elimination of excess iron, body iron is controlled mainly by the degree o...
