The purpose of this study was to determine the changes of oxidative response and exercise-induced muscle damage after two different resistance exercise protocols. Whether training with low or high intensity resistance programs cause alterations in the activities of lipid peroxidation, nitric oxide (NOx), and creatine kinase (CK) activity in human plasma was investigated. Twenty untrained males ...

Background. Exercise has significant affects on free radical production. Objective. The objective of the present study was to explore the effect of vitamin C supplementation on lipid peroxidation and lactate levels in sedentary individuals who performed exhaustion exercised. Methods. 10 healthy sedentary male athletes participated to study. They were supplemented with 300 mg oral vitamin C (L...

Purpose: To evaluate the influence of chlorpromazine (CPZ) on renal function and lipid peroxidation in a rat model of kidney ischemia/reperfusion injury. Methods: Forty eight Wistar rats underwent a laparotomy for hilar clamping of left kidney with a bulldog clamp for 60 minutes followed by organ reperfusion and contralateral nephrectomy. Of these, 26 received 3mg/kg of CPZ intravenously 15 min...

Schistosoma mansoni causes liver disease by inducing granulomatous inflammation. This favors formation of reactive oxygen species, including superoxide ions, hydrogen peroxide and hydroxyl radicals all of which may induce lipid peroxidation. We have evaluated lipid peroxidation in 18 patients with hepatosplenic schistosomiasis mansoni previously treated with oxamniquine followed by splenectomy,...

OBJECTIVES Reactive oxygen species (ROS) induced lipid peroxidation is associated with sperm function. Malondialdehyde (MDA) concentration and glutathione peroxidase (GPx) activity represent the lipid peroxidation and spermicidal antioxidant, respectively. We aimed to evaluate the relationship of MDA and GPx levels with sperm parameters. PATIENTS AND METHODS Specimens were divided into two gr...

The present study investigated the effects of E. coli lipopolysaccharide (LPS) induced mastitis model in rat on the activity of antioxidant enzyme systems. To achieve this purpose, E. coli LPS were infused into the mammary gland of 12 rats 72 hr postpartum and compared with 12 rats in control group infused intramammary placebo sterile pyrogene – free, physiological saline. The...

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...

Although hairdressing is not a dangerous profession, it known that hairdressers are exposed to chemical combinations as allergens, carcinogens or organic solvents. In this study, was aimed determine the levels of superoxide dismutase (SOD), catalase (CAT) and glutathione (GSH), which some important antioxidants, malondialdehyde (MDA), end product lipid peroxidation an indicator oxidative stress...

this study was conducted to investigate the hepatoprotective and antioxidant effects of pentoxifylline (ptx) against aflatoxin b1 (afb1) exposure in perfused rat livers by evaluating damage marker enzymes, antioxidant defense systems (glutathione, gsh) and lipid peroxidation (malondialdehyde, mda). sixteen rats were divided randomly into four experimental groups: control, ptx, afb1 and afb1 + p...

Using high performance liquid chromatographic methods, both plasma and urine lipoperoxide concentrations were measured, as malondialdehyde (MDA), in 30 stable renal transplant patients receiving daily cyclosporine and/or azathioprine therapy. Their MDA concentrations were compared with previously reported reliable reference values using the same liquid chromatographic methods. Although their pl...
