Nadh-methemoglobin Reductase And Reticulocytosis
, 2015 The activity of NADH-methemoglobin reductase varies widely among leprosy patients under dapsone treatment and is negatively correlated to their hemoglobin level. It is supposed that this correlation might be due to an increase in the reticulocyte rate in

Cyanosis by methemoglobinemia in tadpoles of Cochranella granulosa (Anura: Centrolenidae)
Revista de Biología Tropical, 2010 Tadpoles inhabit generally well oxygenated rivers and streams, nevertheless they were found in areas with limited oxygen availability inside the rivers.

Methemoglobin is oxidized hemoglobin that cannot bind to or dissociate from oxygen. In fish, it is most commonly caused by exposure to excess nitrites and can lead to abnormal swimming, buoyancy, or death.

Effects of Strong Oxidants Present in Acer Spp. on Hemolysis Methemoglobin Production in Equine Erythrocytes [PDF]
, 2021 Maple toxicosis is a deadly condition affecting equines after they have ingested wilted leaves of the genus Acer (i.e., maple species). It is characterized by hemolytic anemia and methemoglobinemia.

Hemoglobin in Submicron Particles (HbMPs) Is Stabilized Against Oxidation
AntioxidantsSuperoxide dismutase (SOD) and Catalase (CAT) play a crucial role as the first line of defense antioxidant enzymes in a living cell. These enzymes neutralize the superoxide anion from the autooxidation of oxyhemoglobin (Oxy-Hb) and convert hydrogen ...

Properties of methemoglobin reductase and kinetic study of methemoglobin reduction.
Journal of Biological Chemistry, 1981 A soluble erythrocyte cytochrome b5 was purified as the substrate of methemoglobin reductase and an electron carrier to methemoglobin. The isoelectric point of this protein was at pH 4.3, and E0' was -0.010 at pH 7.0.. The Km value of the enzyme for this protein was 1 x 10(-4) M, and the turnover number (k5) was 3.4 x 10(4) min-1, with NADH as an ...

Methemoglobin formation by paraquat.
Paraquat is a broad spectrum herbicide known to be highly lethal to man and animals. Its toxicity is characterized by acute lung injury. Paraquat produces such toxic effects through the generation of the superoxide anion according to one proposed ...

Symptomatic Methemoglobinemia at Low Levels in a Patient With Obstructive Sleep Apnea
Annals of Internal Medicine: Clinical CasesPreviously reported cases of hypoxemia secondary to methemoglobinemia usually had measured methemoglobin percentages of around 20% or greater. We report an unusual case of methemoglobinemia secondary to dapsone use in a 66-year-old man with obstructive ...
