grape seed proanthocyanidin extract (gspe) has a broad spectrum of biologic properties against oxidative stress. this study aimed to investigate the effects of gspe on biochemical factors and antioxidant enzymes of erythrocyte in diabetic rats. diabetes was induced through single injection of streptozotocin (50 mg.kg-1, i.p). forty male sprague-dawley rats were divided into four groups: group 1...

OBJECTIVE In vitro antioxidant activities of three selected Indian seaweeds viz., Halimeda tuna (H. tuna), Turbinaria conoides (T. conoides) and Gracilaria foliifera (G. foliifera) were evaluated. METHODS Total antioxidant activity, total phenolic content, and reducing power of crude methanol and diethyl ether extracts were determined. RESULTS Total phenolic content and total antioxidant ac...

this study was designed to examine the in vitro antioxidant activities and total phenolic contents of the methanolic extracts from male inflorescence of salix aegyptiaca l. grown in iran. the methanolic extract (me) and its three fractions including water (wf), butanol (bf) and chloroform (cf) were prepared and then their antioxidant activities, as well as total phenolic contents, were evaluate...

introduction: increasing of food-related diseases has led to the perception of diet importance. plant-derived products (especially tea) as important sources of antioxidant and antimicrobial compounds play a major role in reducing food pathogens. in this study, total phenolic content, antioxidant and antimicrobial activity of four tea extracts including green tea, white, black and red teas were ...

Pregnancy in insulin-dependent diabetes mellitus is associated with a greater incidence of fetal abnormality. Animal studies suggested that increased free-radical production and antioxidant depletion may contribute to this risk. The objective of this work was to evaluate oxidative stress and antioxidant capacity in hypertensive, diabetics, and healthy control women during labor. Simultaneous de...

background scrophularia striata (scrophulariaceae family) is an herbaceous plant that is traditionally used for treatment of microbial infections. objectives antimicrobial and antioxidant activity of different extracts (methanolic, ethanolic, aqueous and ethyl acetate) from s. striata aerial parts was evaluated. materials and methods the antimicrobial activity of different extracts from s. stri...

Herb Kalanchoe pinnata is grown as weeds in the tropical countries like India. It has a wide range of active constituents which has potent medicinal properties. The main objective was to overview the total antioxidant capacity of the herb Kalanchoe pinnata. Antioxidant activities were evaluated in terms of total phenolics content, total antioxidant activity, and reducing power. Different studie...

Oxidative stress plays important roles in a wide spectrum of pathological processes, such as atherosclerosis. Although several environmental factors are documented to influence redox metabolism, relatively little is known about genetic effects. In the present study, we evaluated genetic contributions to variation in plasma total antioxidant status (TAS), a measure of peroxyl-scavenging capacity...

chemotherapeutic agents used in patients with cancer cause to generate the enormous amounts of free radicals associated with cell injury. in this study we assess the effects of chemotherapy regimen on oxidant/antioxidant status in patients with acute myeloid leukemia (aml). 38 newly diagnosed patients with acute myeloid leukemia were recruited in this study. all patients received cytarabine and...
