STUDIES OF METHEMOGLOBIN FORMATION

The Formation of Methemoglobin

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

The Formation of Methemoglobin by Streptococcus Viridans

Cultures of Streptococcus viridans when brought into contact with red blood corpuscles have the power of transforming oxyhemoglobin into methemoglobin. The reaction occurs only in the presence of living streptococci when they are able to carry on their metabolic activities. The intensity of the reaction runs roughly parallel with the period of growth and multiplication of the bacteria and gradu...

Methemoglobin Formation in Human Blood by Cobalt

Although the erythropoietic effect of cobalt has been amply demonstrated in experimental animals (1-3), in normal human beings (4, 5), and in certain types of anemia (4, 6-8), the mechanism of this increased blood formation has not been elucidated. No evidence has been adduced that administration of cobalt causes a decrease in oxygen capacity (9) or alters the oxygen dissociation curve (10, 11)...

Studies on the Oxidation-reduction of Hemoglobin and Methemoglobin

Hemoglobin is oxidized to methemoglobin by products formed during the oxidation of a number of different substances. With some of these substances, both oxygen consumption and hemoglobin oxidation are accelerated by thermolabile constituents of pneumococci; with others of the easily oxidized substances, neither reaction seems to be influenced by the presence of the bacterial substances. The sam...
