OBJECTIVE To investigate the causal role of oxidative-stress status on human sperm motility. DESIGN To demonstrate that sperm with higher oxidative damage have a lower antioxidant capacity. SETTING University hospital infertility center. PATIENT(S) Seventy-eight semen samples were obtained from 35 healthy donors who had normal semen characteristics and from 43 infertile or subfertile male...

Hypolipidaemic and antioxidant effects of ethanol extract of mature green fruits of Musa AAA (Chenkadali) was evaluated in alloxan induced diabetic rats. The effect of extract at two doses, 500 mg/kg body weight and 1000 mg/kg body weight was analysed and compared with a standard drug, glibenclamide. Rats administered with alloxan showed significantly increased levels of serum triacylglycerol, ...

The effect of aqueous solution of citric acid (CA) on the lipid stability of the European catfish (Silurus glanis) fillets during frozen storage (up to 6 months) was investigated. Rancidity development was measured by several biochemical indices (free fatty acids, peroxides and TBA) and complemented by the measurement of expressible moisture and sensory evaluation (flesh odor, consistency and f...

Fatty acid peroxides have been found in the atherosclerotic human aorta. Glavind found a correlation between the extent of the atherosclerotic changes and the content of lipid peroxides. These lipid peroxides are very toxic to the tissues. There are several compounds in the tissues to counteract the toxicity of peroxides in vivo, i.e. SH compounds, ascorbic acid, or tocopherol. · It may be infe...

The oxidation of guanosine to 8-oxo-2'-deoxyguanosine (8-oxo-dG) in DNA is closely associated with induction of various diseases, but the endogenous oxidant species involved remains unclear. Hydrogen peroxides (H2O2) have been considered to be the oxidant, while lipid peroxides are another possible oxidant because generated easily in bio-membranes surrounding DNA. The oxidant potency was compar...
