The aim of this study was to estimate the effect of aquatic cadmium and lead pollution on superoxide dismutase (SOD) activity and lipid peroxidation in fish. The study used the fish species Cyprinus carpio L., Oncorhynchus mykiss Walbaum, and Acipenser baeri Brandt. SOD activity was measured by the adrenaline method. Lipid peroxidation was measured by determining malondialdehyde (MDA) concentra...

Cd and Pb represent a serious ecological problem due to their soluble nature, their mobility and ability to accumulate in the soil. The exposure to these heavy metals can originate from different sources (drinking water, food and air), and they can enter into the human body through the respiratory and digestive systems. The effects of glutathione on Cd and Pb accumulation and lipid peroxidation...

Considering drug-induced lipid peroxidation as a possible mediator of drug-induced toxicity and exploiting the free radical scavenging action of antioxidants, the present study was designed to evaluate the protective effects of ascorbic acid (AA) and water extract of Spirulina plantesis (SP) to minimize 5-fluorouracil (5-FU)-induced lipid peroxidation. The study has been performed in vitro usin...

Ascorbic acid stimulates collagen gene expression in cultural fibroblasts (Lyons, B. L., and Schwartz, R. L. (1984) Nucleic Acids Res. 12, 2569-2579), but the mechanisms responsible for this effect are poorly understood. In the presence of the transitional metal iron, ascorbic acid could induce lipid peroxidation with the formation of reactive aldehydes. Since another aldehyde, acetaldehyde, th...

The present study was designed to explore the relationship between lipid peroxidation and antioxidant enzymes in young Malaysian insulin dependant diabetes mellitus (IDDM) patients. Indicative parameters of lipid peroxidation, activities of antioxidant enzymes and diabetes parameters were evaluated in single blood samples from 30 young type 1 diabetic patients and 30 healthy control subjects. A...

OBJECTIVES This study was undertaken to examine the effect of oxidant on lipid peroxidation and lethal cell injury in rat liver slices. METHODS t-Butylhydroperoxide (t-BHP) was employed as a model of an oxidant. The lipid peroxidation and lethal cell injury were estimated by measuring the formation of malondialdehyde (MDA) and lactate dehydrogenase (LDH) release, respectively. RESULTS t-BHP...

background: lipid peroxidation is known to cause various impairments to sperm cells and may play a major role in the etiology of male infertility. asthenospermia is the main factor of male infertility and has significantly higher level of peroxidation than in normozoospermic males. materials and methods: using thiobarbituric acid (tba) assay procedure, we have determined the level of lipid pero...

This study examined the effect of Echis pyramidum (EP) venom on time-course of lipid peroxidation in different vital organs of mice. Adult male Swiss albino mice were injected with EP venom (2 mg/kg, i.p.); control mice received vehicle alone (normal saline). Mice were killed at 1, 3, 6, 12, and 24 h post-envenomation. The liver, lung, kidney, heart, and brain (cerebrum and cerebellum) were col...

The aim of this study is to investigate the effects of epilepsy, valproic acid and oxcarbazepine on nitric oxide levels, lipid peroxidation and xanthine oxidase levels in newly diagnosed epileptic children and healthy controls. A total of 49 patients with newly diagnosed idiopathic epilepsy and 15 healthy children were enrolled in this study. Of these 49 patients, 16 children were treated with ...
