Sodium valproate and tomato extract have been studied in different experimental models of epilepsy individually. The aim of the present study was to evaluate the effect of lycopene on the antiepileptic effects of sodium valproate against pentylenetetrazol-induced kindling in mice. Swiss albino mice of either sex were randomly divided into 5 groups, with each group containing 8 mice. These group...

Dapsone hydroxylamine (DDS-NOH) is a direct-acting hemolytic agent responsible for dapsone-induced hemolytic anemia in the rat. The hemolytic activity of DDS-NOH is associated with the formation of disulfide-linked hemoglobin adducts on membrane skeletal proteins. We have postulated that this membrane protein "damage" is a consequence of DDS-NOH-induced oxidative stress within the red cell and ...

The specificity of an iodometric assay for measuring lipid peroxides in lipoproteins was tested, compared with the fluorimetric thiobarbituric acid assay, and adopted for detecting lipid peroxide in plasma samples. Oxidation of low density lipoproteins in vitro by Cu2+, lipoxidase, and phagocytosing polymorphonuclear leucocytes was sensitively detected by the iodometric assay. Unlike the thioba...

Supraphysiological reactive oxygen species (ROS) has been linked to a variety of diseases, including cancer, inflammation, and neurodegeneration. One the diseases pathophysiologically associated with ROS accumulation is canine distemper (CD). The purpose this study was compare lipid peroxidation antioxidant biomarkers in dogs infected virus (CDV) healthy dogs. animals consisted total 20 dogs, 1...

BACKGROUND Ischemia and subsequent reperfusion induce lipid peroxidation in the cerebrum of the fetal rat. The present study evaluated the antioxidant activity of endogenous coenzyme Q in protecting against the lipid peroxidation induced in the fetal rat brain by ischemia/reperfusion. METHODS We used wistar rats at day 19 of pregnancy. Fetal ischemia was induced by bilateral occlusion of the ...

Decoction and 75% ethanolic extracts from the leaves of Acanthopanax trifoliatus (AT) and Toddalia asiatica (TA) were spectrophotometrically examined for antioxidant activity and phenolics content. Phytochemical characteristics of the decoction extracts were also investigated by thin layer chromatography (TLC). The leaf decoction extract of AT significantly exhibited the highest in vitro antiox...

With dimethyl sulphoxide instead of butanol in the thiobarbituric acid assay for sialic acid, a non-fading chromophore with lambdamax. = 549 nm was produced in a homogeneous solution, allowing dilution of the test mixture in case of high colour yield. This test adapted well to studies on alkaline de-O-acetylation. Bovine and rat submaxillary mucins, and rabbit Tamm-Horsfall urinary sialoprotein...

INTRODUCTION Red blood cell transfusions are common in intensive care units. For many years, transfusions of red blood were thought to have obvious clinical benefits. However, in recent years, the risks and benefits of blood transfusions have been examined more carefully, including the risk of increased morbidity and mortality due to transfusion-related immunomodulation effects. OBJECTIVES To...

Free radical overproduction contributes to tissue damage induced by acute hyperglycemia. Dehydroepiandrosterone, which has recently been found to have antioxidant properties, was administered i.p. to rats at different doses (10, 50 or 100 mg/kg body weight) 3 h before treatment with dextrose (5 g/kg). Lipid peroxidation was evaluated on liver, brain and kidney homogenates, measuring both steady...
