BACKGROUND The metabolic syndrome is a cluster of cardiovascular risk factors and essential components of metabolic syndrome are hyperglycemia, hypertension, visceral obesity, hypertriglyceridemia and low high-density lipoprotein cholesterol. Oxidative stress plays a critical role in the pathogenesis of metabolic syndrome components and insulin resistance.(More)
BACKGROUND The widespread use of mobile phones (MP) in recent years has raised the research activities in many countries to determine the consequences of exposure to the low-intensity electromagnetic radiation (EMR) of mobile phones. Since several experimental studies suggest a role of reactive oxygen species (ROS) in EMR-induced oxidative damage in(More)
Reactive oxygen and nitrogen species have been implicated in the pathogenesis of bleomycin-induced lung fibrosis. The effects of aminoguanidine and erdosteine on the bleomycin-induced lung fibrosis were evaluated in rats. The animals were placed into five groups: Vehicle + vehicle, vehicle + bleomycin (2.5 U/kg), bleomycin + aminoguanidine (200 mg/kg),(More)
Formaldehyde (FA) can cause severe central nervous system impairment. But, there are only a few studies about biochemical and histopathological changes of frontal cortex and hippocampal tissue caused by FA toxicity. The aim of our study was to investigate these changes occurring after chronic formaldehyde toxicity in frontal cortex and hippocampal tissues,(More)
Nigella sativa oil (NSO), a herbaceous plant, has been used for thousands of years for culinary and medical purposes. This study aimed to investigate the anticonvulsant and antioxidant activities of NSO on pentylenetetrazol (PTZ) kindling seizures in mice. Nigella sativa oil was tested for its ability (i) to suppress the convulsive and lethal effects of PTZ(More)
The role of oxygen-derived free radicals has been suggested in genesis of epilepsy and in the post seizure neuronal death. The aim of this study was to investigate whether erdosteine has a preventive effect against epilepsy and postepileptic oxidative stress. The mice (n=27) were divided into three groups: (i) PTZ-induced-epilepsy group (n=9); (ii)(More)
The aim of the present study is to evaluate the status of plasma essential trace element selenium (Se), manganese (Mn), copper (Cu), zinc (Zn), and iron (Fe) concentrations and the effect of these elements on oxidative status in patients with childhood asthma. Plasma Se, Mn, Cu, and Zn concentrations were determined by atomic absorption spectrophotometry(More)
BACKGROUND The aim of this study was to determine the acute effects of antioxidant caffeic acid phenethyl ester (CAPE) and alpha-tocopherol (vitamin E) on nitric oxide (NO) production, neutrophil infiltration, and antioxidant enzyme activities on an in vivo model of renal ischemia-reperfusion injury. METHODS Rats were divided into five equal groups each(More)
The dominant research subject on schizophrenia, mood disorders, autism and other central nervous system diseases has been related to neurotransmitter system abnormalities. For example, the dopamine hypothesis states that schizophrenia is the result of dopaminergic hyperactivity. The therapeutic approach has also been directed towards finding agents which(More)
It is well known that formaldehyde (FA) and reactive oxygen species (ROS) are cytotoxic and potentially carcinogenic. Although the individual effects of these reactants on cells have been investigated, the cytotoxicity exerted by the coexistence of FA and ROS is poorly understood. The present study was carried out to evaluate oxidant/antioxidant status and(More)
