AIM To determine the existence and level of oxidative stress caused by lipid peroxidation in pregnancy. METHODS The research was conducted as prospective examination that included 60 healthy women (age 18-45). The women included in the examination were divided into two groups. The group I (N-31) included women in the first trimester of normal, healthy pregnancy. The group II included healthy ...

Background Lipid peroxidation is known to cause various impairments to sperm cells and may play a major role in the etiology of male infertility. Asthenospermia is the main factor of male infertility and has significantly higher level of peroxidation than in normozoospermic males. MaterialsAndMethods Using thiobarbituric acid (TBA) assay procedure, we have determined the level of lipid peroxida...

Schistosoma mansoni causes liver disease by inducing granulomatous inflammation. This favors formation of reactive oxygen species, including superoxide ions, hydrogen peroxide and hydroxyl radicals all of which may induce lipid peroxidation. We have evaluated lipid peroxidation in 18 patients with hepatosplenic schistosomiasis mansoni previously treated with oxamniquine followed by splenectomy,...

Objective: Type 2 diabetes mellitus is a complex metabolic disorder with adverse cardiovascular risk. Chromium (Cr) is an essential nutrient and its role in carbohydrate and lipid metabolism has not been clarified especially in Iran. The aim of this study was to evaluate the effect of chromium picolinate administration on blood glucose, HbA1c, lipid profile and lipid peroxidation in type 2 diab...

Objective: Diabetes Mellitus (DM) is one of the leading causes of death, illness, and economic loss in the world. The present study was attempted to evaluate extract of Foeniculum vulgare (fennel) on lipid profile, lipid peroxidation and activities of amino transferase enzymes in streptozocin induced diabetic adult male rats. Materials and Methods: The effects of daily oral administration of...

Malondialdehyde (MDA) is a naturally occurring product of lipid peroxidation; it can also be generated during prostaglandin biosynthesis in cells. MDA reacts with amino groups on proteins and other biomolecules to form a variety of adducts, including adducts with DNA bases that are mutagenic and possibly carcinogenic. Increased levels of lipid peroxidation products, by measurement of MDA, have ...

BACKGROUND AND PURPOSE Intracellular accumulation of lipid peroxides that derive from the autoxidation of membrane polyunsaturated fatty acids reduces the deformability of erythrocytes contributing to the hemorheological disturbances observed in acute cerebral ischemia. The present study deals with the biochemical background of increased lipid peroxidation capacity in the erythrocytes of stroke...

Effects of melatonin on the levels of antioxidant enzymes including catalase (CAT), peroxidase (POD), glutathione reductase (GRd), and malondialdehyde (MDA), a lipid peroxidation marker, in erythrocytes of rainbow trout (Oncorhynchus mykiss) were investigated. The results showed that melatonin statistically activated the CAT, POD, and GRd activity (P < 0.05). Moreover, MDA levels were significa...
