haptoglobin (hp) is a mammalian serum glycoprotein showing a genetic polymorphism with three types, 1-1, 2-2 and 1-2. hp appears to conserve the recycling of heme-iron by forming an essentially irreversible but non-covalent complex with hemoglobin which is released into the plasma by erythrocyte lysis. as an important consequence, haptoglobin-hemoglobin complex (hp-hb) shows considerable antiox...

objective: the present study was an attempt to study total phenolic content and antioxidant property of the crude ethanolic extract of the roots of azadirachta indica (a. indica). materials and methods: to evaluate the antioxidant properties of the crude extract, some complementary test systems, namely dpph free radical scavenging assay, reducing power assay, and ferrous ion chelating ability a...

Astaxanthin is the potent antioxidant predominantly found in living organisms that are present marine environment. It known as “King of antioxidant” or “Super vitamin E” because its property. Antioxidant property astaxanthin to modulate different biological activity relating defence system, inflammation, immunity and ameliorating adverse effect oxidative stress during summer season. Its use has...

The ethanol crude extract of stem bark of Holoptelea integrifolia Planch. traditionally used in Indian system of medicine was screened for its antioxidant activity using α-tocopherol as standard antioxidant. The free radical scavenging potential of the extract was evaluated by two different antioxidant methods; ferric thiocyanate and thiobarbituric acid method. The ethanol extract was found to ...

in this work, quantitative structure-property relationship (qspr) approaches were used to predict the redox potential of 42 phenolic antioxidants. the structures of all compounds optimized by the am1 semi-empirical method and then a large number of molecular descriptors were calculated for each compound in the data set. subsequently, stepwise multilinear regression was applied to select the mos...

Aim of the study: To evaluate the antioxidant property of Smilax zeylanica L. using CCl4 hepatotoxicity in rats. Materials and methods: Hepatotoxicity was induced in Wistar albino rats by administration of CCl4 (0.5ml/kg/day p.o. for 7days). Methanol extract of S. zeylanica roots and rhizomes (SZRM) was administered to the experimental animals at doses 200,400 and 600 mg/kg/day, p.o. for 7 days...

This paper is aimed at evaluating the antioxidant properties of Eugenia Caryophyllata (Syzygium aromaticum), 100% aqueous and 20:80% (water alcohol) for hydroethanolic hydromethanolic extracts were prepared as working solutions studies. About 5 different examinations Syzygium aromaticum (Clove) carried out which include total phenolic content, assay, free radical’s DPPH scavenging activity, hyd...

CONTEXT Oxidative stress has crucial role in pathogenesis of diabetic nephropathy (DN). Despite satisfactory results from antioxidant therapy in rodent, antioxidant therapy showed conflicting results in combat with DN in diabetic patients. EVIDENCE ACQUISITIONS Directory of Open Access Journals (DOAJ), Google Scholar,Pubmed (NLM), LISTA (EBSCO) and Web of Science have been searched. RESULTS...
