Biomarkers predicting for the radiation-induced lung responses of pneumonitis or fibrosis are largely unknown. Herein we investigated whether markers of oxidative stress and intracellular antioxidants, measured within days of radiation exposure, are correlated with the lung tissue injury response occurring weeks later. Mice of the eight inbred strains differing in their susceptibility to radiat...
Riboflavin deficiency interferes with the growth and multiplication of malaria parasites as well as the host response to malaria. The objective of the present work was to determine the effects of riboflavin deficiency on erythrocyte glutathione peroxidase (EC 1.11.1.9; GPx) and superoxide dismutase (EC 1.15.1.1; SOD) in rats infected with Plasmodium berghei malaria. Riboflavin in its co-enzyme ...
The modifying effects of garlic (Allium sativum Linn.) on hepatic lipid peroxidation and antioxidant status during 4-nitroquinoline 1-oxide (4NQO)-induced oral carcinogenesis were investigated in male Wistar rats. Enhanced lipid peroxidation in the liver of tumour-bearing animals was accompanied by significant decreases in the activities of glutathione peroxidase (GPx), glutathione S-transferas...
The aim of this study was to investigate the serum levels or activities of oxidative stress markers in patients with schizophrenia in acute phase and evaluate the changes in superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), glutathione (GSH) and thiobarbituric acid-reactive substances (TBARS) after treatment. We consecutively enrolled 41 patients with schizophrenia in ac...
INTRODUCTION Oxidative stress and antioxidants play an important role in the pathogenesis of inflammatory disease, including chronic periodontitis (CP). Saliva contains enzymatic (glutathione peroxidase - GPx, superoxide dismutase - SOD, etc.) and non-enzymatic (albumin - ALB, uric acid - UA, glutathione, etc.) antioxidants. OBJECTIVE The aims of this study were to investigate: a) level of SO...
Glutathione peroxidase (GPx) is a major defense against hydroperoxides as a kind of seleno-enzyme that protects cells from oxidative damage. A supramolecular vesicle with controllable GPx activity and morphology has been successfully constructed by the self-assembly of supra-amphiphiles formed by host-guest recognition between cyclodextrin and adamantane derivatives. By introducing thermosensit...
The general reactivity of membrane lipid hydroperoxides (LOOHs) with the selenoenzyme phospholipid hydroperoxide glutathione peroxidase (PHGPX) has been investigated. When human erythrocyte ghosts (lipid content: 60 wt % phospholipid; 25 wt % cholesterol) were treated with GSH/PHGPX subsequent to rose bengal-sensitized photoperoxidation, iodometrically measured LOOHs were totally reduced to alc...
Background: The aim of this study is to evaluate the effect 50 g oral glucose tolerance test (OGTT) on oxidative stress and interleukin-8 (IL-8) parameters in prediabetic pregnant women. Materials Methods: Fasting 1 hour blood samples were collected from 79 women who administered gr OGTT. Patients with a level 140–200 mg/dl considered as group. Thereafter, routine biochemical levels superoxide ...
