In this study, the malondialdehyde (MDA) levels in the muscle, liver and kidney tissues and the antioxidant vitamin (A, C, E) levels in the muscle tissue of juvenile rainbow trout were investigated under different oxygen levels (3.5 mg O2/l, 4.5 mg O2/l and 7 mg O2/l) at the end of the 8 hour trial. Fish (initial weight and length, 30.19±2.2 g and 13.15±0.22 cm, respectively) were distributed i...

this study was designed to elucidate the effect of ascorbic acid on salivary total antioxidant capacity in smokers. in this single blind crossover clinical trial, the whole unstimulated saliva of 30 smokers, who were randomly divided into two groups, was collected. in the first phase after the saliva collection, one group of patients took 500 mg of vitamin c powder, for 3 weeks. then, saliva of...

objective(s) oxidized low-density lipoproteins (ox-ldls) appear to play a significant role in atherogenesis. in fact, circulating ox-ldl concentrations have been recognized as a risk factor for cardiovascular disease (cvd). the main objectives of this study were to assess the effects of antioxidant vitamins on ox-ldl as a biomarker of cvd in male subjects with cvd risk factors. materials and me...

Although vitamin C supplements were consumed for health maintenance and fatigue recovery, the effects of high doses of vitamin C supplement remains controversial. Our study performed the effects of 100 mg and 2,000 mg vitamin C supplements on plasma and urinary vitamin C concentration in Korean women. Twenty-four women completed the 4 weeks intervention. Anthropometric data, plasma and urinary ...

background: it has been shown that reactive oxygen species (ros) can lead to deleterious effects on a range of sperm parameters. vitamins e and c are capable of reducing ros levels and lipid peroxidation. objective: the aim of study was to determine the level of lipid peroxidation as indicated by malondialdehyde (mda) and vitamins e and c in sperm and seminal plasma of asthenoteratozoospermic a...

rifampin, an antibiotic widely used for the treatment of mycobacterial infections, produceshepatic, renal and bone marrow toxicity in human and animals. in this study, the protectiveeffects of vitamin c and n-acetylcysteine (nac) on the toxicity of rifampin on hepg2 cellswere investigated.human hepatoma cells (hepg2) were cultured in 96-well m of rifampin in the presence ofmicroplate and expose...

natural citrus biotypes are a valuable genetic resource in the country. investigation about diversity of biochemical compounds due to optimize the utilization and development of new varieties is useful. therefore, for identifying them, the fruits of 16 biotypes with numbers of 6, 8, 15, 21, 24, 25, 26, 29, 30, 41, 43, 45, 48, 51, 52 and 53 in the germplasm collection of the iran citrus research...

This experiment investigated the effects of dietary supplementation of vitamin E and vitamin C on sow reproductive performance and transfer of vitamin E to piglets via the placenta, colostrum and milk. A total of 58 sows were allocated to the following treatment diets: control, vitamin C 1 g/day, vitamin C 10 g/day, vitamin E 200 mg/kg feed, vitamin E 400 mg/kg fed, and vitamins E and C (vitami...
