Automated measurement of serum ferroxidase activity.
نویسنده
چکیده
A method is described for automated measurement of serum ceruloplasmin ferroxidase activity. In this method, Fe2+ ions are used as the substrate. In addition, a new calibration system without ceruloplasmin is also presented. Optimum assay reaction conditions were determined. Maximal catalytic activity was obtained at 0.45 mol/L acetate buffer, pH 5.8. The reagents and calibrator are stable for at least 6 months. Significant correlations between serum ferroxidase and p-phenylenediamine oxidase activities (r = 0.96; P <0.0001) and copper concentration (r = 0.93; P <0.0001) were found. The range for serum ceruloplasmin ferroxidase activity in healthy persons was 198-1107 U/L, and in patients with bronchial asthma it was 601-1912 U/L.

Isolation and characterization of the serum ferroxidase inhibitor
strong evidence suggests that the serum ferroxidases (ceruloplasmin andferroxidase II) promote the formation of Fe-III transferrin and thereby stimulate the turnover of iron from tissue stores. Ceruloplasmin is the major ferro.xidase in human serum; whereas, ferroxidase II accotmts for an increased proportion of the activity in less highly developed animals. A large fold increase in total ferro...
متن کاملThe possible significance of the ferrous oxidase activity of ceruloplasmin in normal human serum.
The oxidation of Fe(I1) by serum was studied at pH 7.35 and at various oxygen concentrations which approach the physiological conditions of human serum. The nonenzymic oxidation of Fe(I1) was estimated to be insufficient to account for a rate of Fe(III)-transferrin formation necessary to provide an adequate iron supply for hemoglobin and other biosyntheses if Fe(I1) is a relevant source of seru...
متن کاملAssociation of haptoglobin phenotypes with ceruloplasmin ferroxidase activity in β-thalassemia major.
BACKGROUND Haptoglobin (Hp) and ceruloplasmin (CP) are 2 plasma antioxidants playing a role in preventing iron-induced oxidative damage. This study presents data related to Hp phenotypes and ceruloplasmin ferroxidase activity in relation to iron store markers in patients with β-thalassemia major. METHODS Blood specimens were collected from 196 subjects (124 β-thalassemia major patients and 72...

A 34 year old diabetic man with a complete deficiency of serum ferroxidase activity, regardless of the presence of serum ceruloplasmin (Cp), a multicopper ferroxidase protein, is described. The patient had had diabetes mellitus for 13 years, and was also found to have retinal degeneration accompanied by the development of a hearing disturbance of unknown aetiology. Laboratory examination showed...
متن کاملSerum ferroxidase activity in patients with multiple sclerosis: a pilot study.
Emerging evidence suggests that oxidative stress might contribute to demyelination and axonal damage in multiple sclerosis (MS). Ferroxidase (FeOx) activity of ceruloplasmin prevents the formation of free radicals from Fe(2+) by promoting the incorporation of this pro-oxidant ion to transferrin. The aim of our study was to investigate serum FeOx activity in a cohort of patients with MS and neur...
