Dermatitis Associated With Chromium Following Total Knee Arthroplasty

The Journal of Arthroplasty, 2011
All metal implants release metal ions because of corrosion. Although 20% to 25% of patients develop metal sensitivity after total joint arthroplasty, which is 10% higher than that in the general population, only very few highly susceptible patients exhibit symptoms.

Speciation of chromium by the determination of total chromium and chromium( III ) by electrothermal atomic absorption spectrometry

J. Anal. At. Spectrom., 1993
A method for the determination of chromium(III) and total chromium was studied. Chromium(III) was chelated with 0.1 mol l–1 quinolin-8-ol in methanol, extracted with isobutyl methyl ketone and determined by electrothermal atomic absorption spectrometry.

Chromium Deficiency During Total Parenteral Nutrition

JAMA: The Journal of the American Medical Association, 1979
Chromium is required for maintenance of normal glucose tolerance. After complete bowel resection and five months of total parenteral nutrition, severe glucose intolerance, weight loss, and a metabolic encephalopathylike confusional state developed in a patient. Serum chromium levels were at the lowest normal level. Supplementation of 150 μg of chromium

Portland pozzolana cement in India with respect to total chromium and hexavalent chromium content

Advances in Cement Research, 2011
The objective of the present research work was to evaluate total chromium and hexavalent chromium [Cr(VI)] in Portland cement in India especially for fly ash-based Portland pozzolana cement. Various additives have been used for the effective reduction of Cr(VI) in wet cement.

Spectrophotometric determination of microgram amounts of chromium(VI) and total chromium in waste water

Mikrochimica Acta, 1982
A spectrophotometric method has been developed for the determination of chromium in waste water with 5-Br-PADAP (2-(5-brorno-2-pyridylazo)-5-diethylaminophenol). Chromium(III) forms a blue-purple complex at pH 4.7 upon heating. The color is very stable and is highly sensitive for chromium.

Total chromium and nickel contents of Scottish soils

Geoderma, 1986
Abstract The frequency distributions of chromium and nickel contents in Scottish soils are reported and the relation of the concentrations of these elements to some other soil variables is examined. The frequency distributions of both elements are approximately log-normal and are described in terms of the derived mean ( x ∗ ) and the ...

Total diastereoselective synthesis of chromium cyclopropylcarbene complexes

Tetrahedron Letters, 1995
Abstract Trans -substituted chromium cyclopropylmethoxycarbene complexes 4 have been obtained with total diastereoselectivity through a conjugated addition of in situ generated chloromethyllithium to vinylmethoxycarbene chromium complexes.

Monoclonal Antibody to Trivalent Chromium Chelate Complex and Its Application to Measurement of the Total Chromium Concentration

Analytical Chemistry, 2009
Isothiocyanobenzyl group-appended ethylenediamine tetraacetic acid (EDTA) was used to covalently couple Cr(III) x EDTA to keyhole limpet hemocyanin for use as an immunogen. An obtained monoclonal antibody (RD3G4) bound to Cr(III) x EDTA with an equilibrium dissociation constant (K(d)) of 9.7 nM, which was 100-fold tighter than the K(d)s for the other ...
