Activated polymorphonuclear leucocytes (neutrophils) can generate both intracellular and extracellular luminol dependent chemiluminescence. As luminol dependent chemiluminescence largely measures the activity of the myeloperoxidase-H2O2 system, and as the extracellular activity of this enzyme may be responsible for the tissue damage associated with inflammatory conditions such as rheumatoid art...
Myeloperoxidase (MPO) is a hemoprotein expressed in azurophilic granules of neutrophils and lysosomes monocytes. It caused by mutations the MPO gene on chromosome 17 estimated to affect 1:2000-4000 people. most common inherited defect phagocytes. Microbial killing impaired patients with deficiency, but are asymptomatic, except for diabetic patients. In this article, we aimed present our diagnos...
Hydroquinone, a metabolite of benzene, is converted by human myeloperoxidase to 1,4-benzoquinone, a highly toxic species. This conversion is stimulated by phenol, another metabolite of benzene. Here we report that peroxidase-dependent hydroquinone metabolism is also stimulated by catechol, resorcinol, o-cresol, m-cresol, p-cresol, guaiacol, histidine, and imidazole. In order to gain insights in...
The relationship between the toxic effect of propylthiouracil (PTU) and myeloperoxidase activity of rat bone marrow was examined. The administration of PTU for 1 or 2 weeks caused a decrease in leukocyte count with the concomitant inhibition of the activity of myeloperoxidase in the bone marrow. The decreases in both leukocyte counts and myeloperoxidase activity were restored to control levels ...
