Over production of free radicals result in oxidative stress that deregulates the cellular and metabolic functions. Phytochemicals with antioxidant property are of great interest due to their beneficial effects on human health as they offer protection against metabolic dysfunction, gastro-duodenal pathogenesis, premature aging, inflammation, rheumatoid arthritis, atherosclerosis, cancer, neuro-d...

Triphala, an Indian ayurvedic triherbal formulation, is an equiproportional mixture of fruits of three herbs, amalaki (Emblica officinalis), haritaki (Terminalia chebula) and bibhitaki (Terminalia bellerica). The present study focused on phytocompounds detection and comparative analysis of various biochemical activities in the aqueous and methanolic extracts of triphala and its constituting her...

Radical scavenging activity of ethanolic extract of Trianthema triquetra root was investigated against CCl4 in rats. The rats were treated with T. triquetra (100 mg, 200 mg/kg b.w.) for a period of 7 days. Antihepatotoxic effect was studied by assaying the activities of thiobarbituric acid (TBARS), reduced glutathione (GSH), glutathione peroxidase (GPx),catalase (CAT), super oxide dismutase (SO...

The free radical scavenging potential of the plant Alocasia indica(Linn.) was studied by using different antioxidant models of screening like scavenging of 1,1-diphenyl-2-picryl hydrazyl radical, nitric oxide radical, superoxide anion radical, hydroxyl radical, iron chelating activity, total antioxidant capacity, non-enzymatic glycosylation of haemoglobin, rapid screening for antioxidant compou...

The antioxidant activity of Marrubium peregrinum essential oil, collected from three different locations [Backo Gradiste Rimski Sanac (No.1), Novi Knezevac (No.2) and Senta (No.3)] was evaluated as free radical scavenging capacity (RSC), together with inhibition on xanthine-oxidase and effects on lipid peroxidation (LP). RSC was assessed measuring the scavenging activity of the essential oils o...

Free radical formation has been investigated in diverse experimental models of LPS-induced inflammation. Here, using electron spin resonance (ESR) and the spin trap alpha-(4-pyridyl-1-oxide)-N-tert-butylnitrone, we have detected an ESR spectrum of alpha-(4-pyridyl-1-oxide)-N-tert-butylnitrone radical adducts in the lipid extract of mouse skin treated with LPS for 6 h. The ESR spectrum was consi...

costus speciosus (koen) j.e. sm. plant and its extracts are used for treatment of fever, snake bites, jaundice, and as a purgative, astringent and antibacterial agent. in the present study, an attempt has been made to evaluate in vitro antioxidant activity of different extracts of this plant by dpph radical scavenging activity, total antioxidant capacity, nitric oxide scavenging activity, ion c...

OBJECTIVE To investigate the effects of lidocaine on the morphology of saphenous veins (SVs) harvested during coronary artery bypass graft (CABG) surgery. METHODS This experimental study was conducted at the Cardiovascular Surgery Department, Gazi University, Ankara, Turkey, between May and September 2007. The SVs from 11 patients who underwent CABG surgery were divided into 3 segments. Each ...

objective(s): this study describes the preparation, biodistribution of 153sm-dtpa-spion after intravenous injection in rats. materials and methods: the chelator dtpa dianhydride was conjugated to spion using a small modification of the well-known cyclic anhydride method. conjugation was done at a 1: 4 (spion: ccdtpa) molar ratio. conjugation reaction was purified with magnetic assorting column ...

The antioxidant activity of defatted ethanolic extract of the leaves of Blumea mollis were studied for its free radical scavenging property on different in vitro antioxidant models like DPPH radical, hydroxyl radical, nitric oxide radical scavenging activity, reducing power, superoxide anion radical scavenging activity were analyzed. The extract showed free radical scavenging property in dose-d...
