The aim of this study was to determine which oxidant–antioxidant blood markers are of interest for a field exercise test (ET) performed on a racetrack. Healthy Standardbred horses (S: n 1⁄4 12) and healthy eventing horses (E: n 1⁄4 12) were investigated. Exercise was monitored by measuring velocity (V), heart rate (HR), and plasma lactate (LA). Whilst maximal LA did not differ (11.8 ^ 0.88 mmol...

The potency of Solenostemma argel (asclepiadaceae) as anti-inflammatory and antioxidant effects was investigated. Three solvent extract were used for extracting (polyphenolic, flavonoids and tannins) from the leaves of Solenostemma argel (S. argel). Three complementary antioxidant systems: (DPPH∙ free radical scavenging, Fe2+-chelating and iron reducing power) as well as the total phenolic, tot...

background: hyperthyroidism is associated with liver oxidative stress causing liver dysfunction in many hyperthyroid patients. the hepatoprotective effect of satureja khuzestanica essential oil (skeo), as herbal origin antioxidant and anti-inflammatory agent on the hyperthyroidism induced hepatotoxicity and oxidative stress is investigated. methods: adult male sprague dawley rats were divided i...

the plants of the genus salvia synthesize several types of secondary metabolites with antimicrobial, cytotoxic, and radical scavenging activities and are used in the folk medicine of different countries. eleven salvia species including s. aegyptiaca, s. aethiopis, s. atropatana, s. eremophila, s. hypoleuca, s. limbata, s. nemorosa, s. santolinifolia, s. sclarea, s. syriaca, and s. xanthocheila ...

Recently, Kwon et al. reported that the antioxidant activity and total both polyphenol and flavonoid contents of garlic juice were increased by high temperatureand pressure-treatment (130°C, 120 min). We tried to make high temperatureand pressure-treated garlic (HTPG) using an autoclave (130°C, 150 min) rapidly and easily. Our attempt showed that antioxidative activity and total polyphenol cont...

OBJECTIVE The oxidative stress in 20 sickle cell anemia patients taking hydroxyurea and 13 sickle cell anemia patients who did not take hydroxyurea was compared with a control group of 96 individuals without any hemoglobinopathy. METHODS Oxidative stress was assessed by thiobarbituric acid reactive species production, the Trolox-equivalent antioxidant capacity and plasma glutathione levels. ...

Grape juices are an important source of food antioxidants. Unfortunately, there is little data about the mineral composition and the antioxidant, mutagenic and antimutagenic activities of grape juice in eukaryote cells. We evaluated the mineral contents (Mg, Ca, Mn, Fe, Cu, Zn, Si, S, Cl) of grape juices, the antioxidant, mutagenic and/or antimutagenic activities of the juices in the yeas...

Fourteen Solanum cultivars (S. aculeatissimum, S. melongena, S. torvum, S. trilobatum, S. stramonifolium, S. mammosum and S. wrightii) and fourteen Capsicum cultivars (C. annuum, C. frutescens and C. minimum) cultivated in Thailand were determined their total phenolic contents in term of gallic acid (g) per 100 g of crude extract and per 100 g of dry herb powder. The total phenolic content of S...

We examined the response to hydrogen peroxide of two L5178Y (LY) sublines which are inversely cross-sensitive to hydrogen peroxide and X-rays: LY-R cells are radio-resistant and hydrogen peroxide-sensitive, whereas LY-S cells are radiosensitive and hydrogen peroxide-resistant. Higher initial DNA breaks and higher iron content (potentially active in the Fenton reaction) were found in the hydroge...
