A MONOCYANO-EDTA COBALTATE(III) COMPLEX: Na2[Co(CN)edta]·4H2O

Lead EDTA complex, a water-soluble contrast medium.

Redox reactions of a Ru(III)-edta complex with thioamino acids. Kinetic and mechanistic studies.

The kinetics of reduction of [Ru(III)(edta)pz]⁻ (edta⁴⁻ = ethylenediaminetetraacetate; pz = pyrazine) by thioamino acids (RSH = cysteine, glutathione) resulting in the formation of a red [Ru(II)(edta)pz]²⁻ species (λ(max) = 462 nm) has been studied spectrophotometrically using both conventional mixing and stopped-flow techniques. The time course of the reaction was followed as a function of [RS...

EDTA Chelation Therapy

This study measured excretion of 11 minerals induced by EDTA chelation therapy in 25 adults (aluminum, cadmium, calcium, chromium, copper, iron, lead, magnesium, manganese, mercury, zinc). We administered 20 EDTA infusions (3 g, with magnesium and ascorbate) 1 to 2 weeks apart and measured 24-hr urinary excretions of minerals before treatment and after treatments 1, 10, and 20. A modest supplem...

EDTA-dependent lymphocyte clumping.

A 79-year old man presented with chest pain and fatigue. He was found to have anemia (hemoglobin 8.8 g/dL) and leukocytosis (white blood cell count 244x10/L) with a predominance of lymphocytes (94%). Flow cytometric study and flourescence in situ hybridization analysis of the peripheral blood lymphocytes were consistent with a diagnosis of mantle cell lymphoma. A peripheral smear obtained from ...

EDTA (Ethylenediaminetetraacetic Acid)

Ethylenediaminetetraacetic acid (EDTA) was developed by Franz Munz inGermanyduring the 1930s as an alternative to citric acid. About the same time, Frederick Bersworth synthesized EDTA in the United States using a different technique. He obtained aUSpatent for this technique in1945. EDTAwas approvedby the US Food and Drug Administration (FDA) as a food additive in 1947. Since the early 1950s, E...
