Background: Probiotics have attracted a great attention aiming to develop natural non-toxic antioxidants, because of their role in decreasing the risk of reactive oxygen species (ROS) accumulation. Objectives: The purpose of this study was to assess the antioxidant activity of a probiotic Streptococcus salivarius ssp thermophillus (St.sa) and to evaluate its protective effect against the ...

the effect of long-term onion consumption on red blood cell antioxidant enzymes [glucose-6-phosphate dehydrogenase (g6pd), superoxide dismutase (sod) and glutathione peroxidase (gpx)], were measured. the relationship of these enzymes with pcv and hemoglobin (hb) concentrations was also determined. twelve adult female goats were used for the experiment and randomly assigned to three groups. anim...

Background: Nitrogen is the most important nutrient requirement for plants. Nitrogen supplying affected the leaf area, carbon fixation, glandular trichomes formation, ATP and NADPH content which resulted to the terpenoids biosynthesis enhancement and essential oils accumulation. Objective: This study was aimed to evaluate changes of essential oil content and components by use different levels ...

doxorubicin (dox) induces oxidative stress leading to cardiovascular abnormalities. green tea extract (gte) is reported to possess antioxidant activity mainly by means of its polyphenolic constituent, catechins. our study was aimed to find out the effect of gte (100 mg/kg / day p.o. for 28 days) on dox induced (3 mg/kg, ip on days 1, 7, 14, 21, 28) cardiovascular abnormalities in rat heart. dox...

drought is still accounted as a serious agronomic problem and also one of the most important factors contributing to crop yield loss. the effect of sodium silicate (na2sio3, abbreviated as si) was investigated on the four major antioxidant enzyme activities and five other relevant components in two different grapevine cultivars (vitis vinifera l., cvs mish pestan and sahebi, as tolerant and sen...

background:in recent years, the use of chemicals in agriculture, industry, and public health has become so common that the environment is continuously contaminated by the toxic substance-like metals. aluminum released due to anthropogenic activities such as mining and industrial uses. aluminium has several industrial uses. the present study was designed to investigate the effect of aluminium ch...

The aim of the study was the evaluation of cadmium effects on the activity of antioxidant enzymes in rat hepatocytes. The studies were conducted with isolated rat hepatocytes incubated for 1 or 2 hours in a modified (deprived of carbonates with phosphates) Williams' E medium (MWE) in the presence of cadmium chloride (25, 50 and 200 microM). Hepatocytes incubated in the MWE medium without cadmiu...
