Aim: local bacteria stimulate polymorphonuclear neutrophils to release reactive oxygen species in periodontitis increased levels of oxidative stress play a significant role in the pathogenesis of periodontitis therefore, this study aimed to evaluate total salivary and serum antioxidant capacity. Oxidative stress is an imbalance between the antioxidant defense system and the formation of oxidative free radicals the result from this disturbance is lipid peroxidation, dna modifications and secretion of pro-inflammatory cytokines [ 8 . Oxidative stress is caused by an imbalance between the production of pro-oxidants and the capacity of a biological system of rapid detoxification of free radicals in this paper the level of pro-oxidants and antioxidants.
Oxidative stress is a cellular condition where cells are challenged by elevated levels of reactive oxygen species (ros) that are produced endogenously or exogenously ros can damage vital cellular components, including lipid, protein, dna and rna. Phd thesis study of oxidative stress and the antioxidant defense system after heavy metal treatment in carp and in streptozotocin-induced diabetic rats. Psoriasis is a skin disease that causes itchy or sore patches of thick, red skin with silvery scales you usually get the patches on your elbows, knees, scalp, back, face, palms and feet, but they can show up on other parts of your body. Stress occurs when the antioxidant defense system in the cell becomes overwhelmed there are many different forms of oxidants, including reactive oxygen species (h 2 o 2 , o 2 and oh), reactive nitrogen species (no and onoo - ), and carbon centered radicals.
When researchers from the aligarh muslim university in india compared oxidative stress in people diagnosed with ra to people without this disease, the ra sufferers had high levels of oxidative stress, including increased ros production, dna damage, impaired antioxidant defense systems, and other markers. Oxidative stress is accepted as a significant pathology, there is currently an inadequate knowledge of the exact mechanisms by which oxidative stress develops in male infertility, as well as a lack of an easy and reliable method for the. Keywords: psoriasis, lipid peroxidation, total antioxidant status, oxidative stress, enzymatic antioxidants introduction psoriasis is a common chronic, inflammatory, proliferative skin disease that generally presents as chronic sharply demarcated, dull red, scaly plaques, particularly on extensor prominences and the scalp [ 1 , 2 . Oxidative stress has been implicated in the development and progression of numerous diseases, even psoriasis below figure illustrates the importance of oxidative stress that can affect all organs in our body and contribute to multiple health problems.

Previous findings have indicated that oxidative stress plays a role in the development of osteoporosis and that individual polyphenols, by virtue of their antioxidant properties, may mitigate these damaging effects. Oxidative stress may play a role either in triggering the defect or accelerating the onset of the disease after the defect happens although genetic defects are believed. Indeed, several studies have revealed increased levels of oxidative stress markers and decreased activity of the main antioxidant enzymes in the plasma of psoriatic patients [12. Role of oxidative stress in diabetic complications the balance between the rate of free radical generation and elimination is important excess cellular radical generation can be harmful10 however, if there is a significant increase in radical generation, or a decrease in radical elimination from the cell, oxidative cellular stress ensues11 there is convincing experimental and clinical.
Key words: antioxidants, erythrocyte, neutrophil, oxidative stress, psoriasis psoriasis is a chronic and recurrent inﬂammatory skin disease, known as an oxidative stress condition 1,2 as. The key role of ros in the pathogenesis of psoriasis has been already reported [6,7] indeed, several studies have revealed increased levels of oxidative stress markers and decreased activity. Nfe2l1 can protect cells from oxidative stress by regulating genes encoding enzymes related to glutathione (gsh) biosyn- thesis and other oxidative defense enzymes [10. Free radicals are generated by normal physiologic processes, including aerobic metabolism and inflammatory response, but may inflict cellular damage when generation is increased and antioxidant defense mechanisms are overwhelmed. Tac depletion, caused by the oxidative stress, is triggered by release of the stocks of antioxidants in the body, especially from the liver and adipose tissue and by induction or activation of antioxidant enzymes (lamont and others 1997, cao and prior 1998, ghiselli and others 2000.
So, to conclude, the jury is still out on what role antioxidants can and should play in the treatment of psoriasis, and large-scale studies testing different types of antioxidant therapies and formulations are needed. Intake of antioxidants through diet and topical application in the form of skin care products helps reduce oxidative stress and damage, minimize the appearance of signs of aging, and it aids management of different skin diseases. Psoriasis, another t‐cell‐mediated skin disorder, exhibits increased oxidative stress in lesional fibroblasts and reduced antioxidant capacity similarly, perturbations of oxidative stress occur in lichen sclerosus, which shares clinical features with erosive lichen planus of the vulva 3 however, no studies have yet investigated the.
Oxidative stress (os) and formation of free radicals oxidative stress (os) occurs when the production of free radicals or their products are in excess of antioxidant defense mechanisms. Authors also have studied role of antioxidants in reducing oxidative stress they have come across with controversial results and furthermore it is not yet fully confirmed whether oxidative stress increases the need for dietary antioxidants. Mitochondria psoriasis pasi score apoptosis cytochrome c oxidative stress antioxidant status antioxidant enzymes introduction chronic psoriasis is an immune-mediated inflammatory skin condition occurs before the age of 35 and affecting approximately 2 % of the general population. An attempt is made to discuss the multistep pathogenic indulgence of oxidative stress to emphasize the worth attention to dietetic intervention toward rational and desired management of psoriasis keywords: psoriasis, oxidative stress, antioxidants, apoptosis, keratinocyte.
