BACKGROUND AND OBJECTIVES Rheumatoid arthritis (RA) is a chronic multisystem disease of unknown cause. Formation of reactive oxygen species and lipid peroxides as a result of disease activity may play an important role. Oxidative stress and decreased antioxidant status are the hallmarks in patients of RA as observed in recent years. The objectives of the study was to determine oxidative stress ...

BACKGROUND AND OBJECTIVES The diet is a key environmental factor implicated in health and disease. Oxidative stress, antioxidant status and their relation to diet is a subject of interest in recent years. The objective of the study was to compare lipid peroxidation and antioxidant status in healthy vegetarians and non-vegetarians. METHODS The present study comprises 100 healthy individuals (5...

Earthworms have been widely used in traditional medicine for thousands of years. However, it is only during the past few decades, with the development of biochemical technologies, that research on the pharmaceutical effects has been initiated. The present study was carried out to investigate the hepatoprotective and antioxidant properties of indigenous earthworm powder (Perionyx excavatus), usi...

Mucuna pruriens Linn., a leguminous plant, has been recognized as an aphrodisiac and spermatogenic agent. Protective efficacy of M. pruriens on reactive oxygen species (ROS)-induced pathophysiological alterations in structural and functional integrity of epididymal sperm in aged Wister albino rat was analysed. Animals were grouped as groups I, II, III and IV, i.e. young (control), aged, aged tr...

Patients with diabetes mellitus are likely to develop certain complication such as retinopathy, nephropathy and neuropathy as a result of oxidative stress and overwhelming free radicals. Treatment of diabetic patients with antioxidant may be of advantage in attenuating these complications. Oleuropein, the active constituent of olive leaf (Olea europaea), has been endowed with many beneficial an...

The present study evaluated the in vitro anticataract and antioxidant activities of ethanolic seed extract of Abrus precatorius Linn. (Fabaceae) against calcium-induced cataractogenesis using goat lenses. Transparent isolated goat lenes were incubated in artificial aqueous humor and divided into seven experimental groups. The extracts at a dose of 100 μg/ml and 200 μg/ml were incubated simultan...

SARAL, Y., COSKUN, B.K., OZTURK, P., KARATAS, F. and AYAR, A. Assessment of Salivary and Serum Antioxidant Vitamins and Lipid Peroxidation in Patients with Recurrent Aphthous Ulceration. Tohoku J. Exp. Med., 2005, 206 (4), 305-312 ── Recurrent aphthous ulceration (RAU) is a common oral mucosal disorder characterized by recurrent, painful oral aphthae. Although the exact cause of RAU is not know...

Mobile telephones and their base stations are an important ultra high frequency-electromagnetic field (UHF-EMF) source and their utilization is increasing all over the world. Epidemiological studies suggested that low energy UHF-EMF emitted from a cellular telephone may cause biological effects, such as DNA damage and changes on oxidative metabolism. An in vivo mammalian cytogenetic test, the m...

This study reports the experimental findings and plasma delivery approach developed at the Plasma Bioscience Research Center, Korea for the assessment of antitumor activity of dielectric barrier discharge (DBD) for cancer treatment. Detailed investigation of biological effects occurring after atmospheric pressure non-thermal (APNT) plasma application during in vitro experiments revealed the rol...
