Ozone therapy is not officially allowed in many countries, but private medical services are using this therapy worldwide. However, appropriate control systems to assess the benefits and risks of systemic ozone therapy are not always used and in such cases the treatment is based on anecdotal reports. Oxidative stress phenomenon is becoming a highlighted biological process for ozone therapy becau...

BACKGROUND Hemodynamically significant patent ductus arteriosus (hsPDA) leads to injury in tissues/organs by reducing perfusion of organs and causing oxidative stress. The purpose of this study was to evaluate the oxidant/antioxidant status in preterm infants with hsPDA by measuring the total antioxidant capacity and total oxidant status and to assess neuronal damage due to oxidant stress relat...

BACKGROUND Whereas coronary artery ectasia (CAE) is a rare abnormality of the coronary arteries, co-existent coronary artery disease (CAD) is commonly seen in CAE patients. Since a causative relationship has been shown to exist between oxidative stress and CAD, we sought to determine whether any relationship exists between oxidative stress and CAE. METHODS Fourty four patients with CAE (witho...

Behcet's disease (BD) is a chronic systemic inflammatory disease. Inflammatory reactions trigger the oxidative stress and oxidants decrease the level of antioxidants. In the present study, we aimed to determine serum oxidative/antioxidative status in patients with BD. Serum antioxidative status was evaluated by measuring total antioxidant capacity (TAC), paraoxonase 1, arylesterase, sulfhydryl ...

AIM Ethanol causes oxidative degradation of the mitochondrial genome in the brain. This effect could contribute to the development of brain injury in some alcoholic patients. We investigated the protective effect of caffeic acid phenyl esther (CAPE) and intralipid (IL) on oxidative stress and neurotoxicity induced by ethanol intake. MATERIAL AND METHODS The forty-eight rats were randomly divi...

We evaluated the association of indices of paraoxonase (PON1) and oxidative status with subclinical cardiovascular disease (CVD) in mixed-ancestry South Africans. Participants were 491 adults (126 men) who were stratified by diabetes status and body mass index (BMI). Carotid intima-media thickness (CIMT) was used as a measure of subclinical CVD. Indices of PON1 and oxidative status were determi...

Background and objectives: Increased oxidative stress and altered antioxidant levels play an essential role in the pathogenesis of diabetes mellitus. Menopause is associated with increased food intake, weight gain, metabolic disorders, and increased level of inflammatory and oxidative stress factors. This study evaluated effects of oleuropein extract on brain tissue and serum oxidative status i...

Objective: Oxidative stress is involved in the pathophysiology of diabetes and cardiovascular complications of metabolic syndrome. The main objective of this study was to evaluate total antioxidant status by diphenylpicrylhydrazyl (DPPH)-scavenging activity in patients developed metabolic syndrome (MetS). Materials and Methods: Forty-four patients with MetS diagnosed on the basis of adult tre...

Exposure to oxygen-rich environments can lead to oxidative damage, increased body iron stores, and changes in status of some vitamins, including folate. Assessing the type of oxidative damage in these environments and determining its relationships with changes in folate status are important for defining nutrient requirements and designing countermeasures to mitigate these effects. Responses of ...
