BACKGROUND We established a rabbit VX2 cell liver carcinoma model to evaluate effects of ischemia reperfusion (IR) on reactive oxygen species (ROS) development and liver cell apoptosis rates. METHODS Thirty-six rabbits were divided into a control (n=6) and a VX2 hepatocellular carcinoma (HCC) model group (n=30), which received VX2 cell suspension injections into their livers. From the 30 HCC ...

BACKGROUND/AIM Pro-free radical oxidative stresses, as well as regulatory factors, are believed to be the key players in the development of diabetes and heart-related disorders such as myocardial infarction. The aim of the present study was to highlight the role of oxidative stress-responsive factors (reactive oxygen species [ROS], super oxide dismutase [SOD], and calpain-1) in type 2 diabetes ...

Madecassoside (MA), one of the principle terpenoids in Centella asiatica, has shown protect effect on isolated rat hearts and isolated cardiomyocytes against reperfusion injury in our previous studies. The aim of this study is to investigate if MA also protected against myocardial ischemia-reperfusion injury in vivo. The ischemia infarction model was established in rats. Left ventricular functi...

This study was designed to evaluate the protective activity of gallic acid (GA) against glyoxal (GO) an advanced glycation intermediate-induced renal fibrosis in experimental rats. Glyoxal (i.p) at a dose of 15 mg/Kg body weight/day for 4 weeks induces renal fibrosis. GA was administered orally (100 mg/Kg body weight/day) along with GO for 4 weeks. The anti-fibrotic activity of GA was analyzed ...

OBJECTIVE It has been shown that oxidative stress plays an important role in development of noise induced hearing loss. Since static magnetic fields (SMF) exposure may alter dynamics of oxidative processes in the tissue, the aim of the study was to assess the influence of SMF on noise-induced alteration in the cochlear level of reactive oxygen species (ROS) and hearing thresholds. MATERIALS A...

Introduction: Oxidative stress is an imbalance between the formation of Reactive oxygen species and protective antioxidant defense. It is known that oxidative stress increases the Acute renal failure. Measurement of oxidative stress parameters may be a simple tool for monitoring the progression of acute renal failure. Aim: The aim of this study was to evaluate oxidative stress in acute renal fa...

Marfan syndrome (MFS) is associated with progressive aortic dilatation, endothelial dysfunction, and oxidative stress that contribute to the early acute dissection of the vessel and can end up in rupture of the aorta and sudden death. Many studies have described that the organic acids from Hibiscus sabdariffa Linne (HSL) calyces increase cellular antioxidant capacity and decrease oxidative stre...

Various effects of exposure to volatile organic compounds (VOC) have recently become an important issue because of their widespread use in industry. The aim of this study was to determine the effect of volatile organic solvents commonly used in textile paint industry on free radical levels and the antioxidant enzyme system in textile workers. The study included twenty exposed workers and twenty...
