Catalysis of Methemoglobin Reduction

1984
Publisher Summary This chapter focuses on the catalysis of methemoglobin reduction. It discusses the results of studies in which photometry and magnetic circular dichroism (MCD) spectroscopy were used to follow the kinetics of methemoglobin reduction.

Deficiencies and Improvement of Methemoglobin Assay

Journal of Analytical Toxicology, 1984
A day-to-day variability in results was encountered when using the Dubowski method for the routine clinical determination of methemoglobin in blood. Therefore, studies were performed to determine the source(s) of variability in the method as described by Dubowski.

Methemoglobin Reductase Deficiency in a Dog

Journal of the American Veterinary Medical Association, 1974
SUMMARY In a case of canine methemoglobinemia the only significant clinical findings were brownish mucous membranes and dark, brownish blood. Chemical analysis indicated a methemoglobin concentration that was approximately 30% of the total hemoglobin.

Reduction of methemoglobin by tetrahydropterin and glutathione

Archives of Biochemistry and Biophysics, 1977
Abstract The reduced pteridine 2-amino-4-hydroxy-6,7-dimethyl-5,6,7,8-tetrahydropteridine nonenzymatically reduces methemoglobin in solution and in intact erythrocytes. The extent of the reaction in whole cells is markedly increased in the presence of glucose.

A New Method for the Reduction of Methemoglobin and Methemoglobin Derivatives

1991
Abstract : The chemical reduction of methemoglobin (metHb) with dithionite and other reducing agents has proven unsatisfactory due to undesirable byproducts. We have now developed a method to reduce methemoglobin on a preparative scale, in which metHb is reduced using photoactivated flavin mononucleotide (FMN). The reduction is performed in the absence

Methemoglobin pathophysiology.

Progress in clinical and biological research, 1981
The biochemical processes involved in the formation of methemoglobin, in the protection of hemoglobin against oxidation to methemoglobin, and in the reduction of methemoglobin to hemoglobin are reviewed. Special emphasis is directed to the major and minor metabolic pathways in human erythrocytes that are involved in the reduction of methemoglobin, and ...
