Chelation of cadmium.
The toxicity of cadmium is determined by chelation reactions: in vivo, Cd2+ exists exclusively in coordination complexes with biological ligands, or with administered chelating agents. The Cd2+ ion has some soft character, but it is not a typical soft ion. It has a high degree of polarizability, and its complexes with soft ligands have predominantly covalent bond characteristics. Cd2+ forms the...
متن کاملChelation of cadmium without increased renal cadmium deposition.
Cadmium (Cd) is mainly accumulated in liver and kidney bound to metallothionein (MT) and excreted very slowly from the body. In chronic exposure, Cd is gradually transported from liver to kidney; the renal toxic effects appear when renal Cd concentration exceeds the critical concentration. In order to prevent the Cd-induced renal disease, it is important to control the movement of Cd to the kid...
متن کاملEffect of glutathione on the cadmium chelation of EDTA in a patient with cadmium intoxication.
In order to evaluate the efficiency and renal protective effects of glutathione during Ca(++)-EDTA chelation therapy for chronic cadmium intoxication, we measured the renal excretion of cadmium, β(2)-microglobulin, proteinuria, and hematuria during intravenous administration of glutathione with Ca(++)-EDTA in a 54-year-old patient with chronic cadmium intoxication. We administered 500 mg of Ca(...
متن کاملChelation reactions of adenine.
Chelation reactions of the antimitotic drug, 6-amino-purine (adenine; abbr. ADN) with the metal ions: Be ( I I ) , AI ( I II ) , Cr ( I I I ) , M n ( I I ) , Fe ( I I I ) , Co (II ) , N i ( I I ) , C u ( I I ) , P b ( I I ) , and U 0 2 ( I I ) have been investigated in aqueous solution at 3 0 ° using B j e r r u m C a l v i n pH titration technique. The formation constants have been determined ...
متن کاملdevelopment of different optical methods for determination of glucose using cadmium telluride quantum dots and silver nanoparticles
a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...
