O-8: Study of Peroxynitrite Levels, Arginase Activity and NO Synthase Activity in Seminal Plasma of Iraqi Leukocytospermic Patients
Background Leukocytes linked directly and indirectly to reactive oxygen species (ROS) formation. Although leukocytospermia is defined as the presence of ≥1×106 white blood cells/mL (WBC/mL) in a semen sample, the presence of less than 1×106 WBC/mL (low-level leukocytospermia) still can produce a detectable amount of ROS, impairing sperm function and lowering the chances of pregnancy. Low concen...
متن کاملStudy of the effects of oral zinc supplementation on peroxynitrite levels, arginase activity and NO synthase activity in seminal plasma of Iraqi asthenospermic patients
BACKGROUND Low concentrations of nitric oxide (NO) are necessary for the biology and physiology of spermatozoa, but high levels of NO are toxic and have negative effects on sperm functions. Although several studies have considered the relationship between infertility and semen NO concentrations, no study on the effects of asthenospermia treatments such as oral zinc supplementation on concentrat...
متن کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...

study the effects of low level laser diode on no production and healing of diabetic and cortisone acetate and normal wounded sd rats
nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...
