free radicals involved in a number of diseases due to the oxidative damage to dna, lipids, and proteins and which can result in failure of cellular functions. dried plant bulbs and leaves methanolic and ethanolic extracts were prepared. total antioxidant activities of the methanolic extracts of romulea ramiflora and gagea fibrosa were determined using β-caroten-linoleic acid assay. romulea-bulb...

objective(s) the objective of this study was to determine the effect of aqueous extract of origanum vulgare l. ssp. viridis (org) on discrimination learning and long term potentiation (ltp) in ca1 region of the rat hippocampus. materials and methods a group of adult male wistar rats weighing 275±25 g received aqueous extract of org (150, 300, 450 mg/kg/day) by intraperitoneal injection for one ...

Aim. This study was aimed at evaluating prooxidant-antioxidant balance (PAB) in patients with systemic lupus erythematosus (SLE) and its relationship with laboratory findings and clinical manifestations. Methods. In this case-control study, 60 patients with SLE and 60 healthy individuals were enrolled. The blood samples were collected and their sera were separated. Subsequently, the prooxidant-...

Herb and spices namely kesum, ginger and turmeric were extracted by using juice extractor without the additional of solvent. These herb and spices were determined for moisture content and the extracts were analyzed for total phenolic content (TPC) and antioxidant activity (DPPH radical scavenging assay and FRAP ferric-reducing antioxidant power assay). The yield of kesum, ginger and turmeric ex...

The present study was designed to investigate the antioxidant and antitumor activities of Alangium salviifolium (AS) wang flowers. Antioxidant potential of the AS extract was evaluated in vitro by DPPH (1,1diphenyl-2-picrylhydrazyl) scavenging assay and reducing power assay method. AS extract showed scavengin-g activity in all the methods with IC50 value of 182.31 ± 0.31 μg/ml for DPPH assay me...

Stroke is the third most common cause of death worldwide, and most stroke survivors present some functional impairment. We assessed the striatal oxidative balance and motor alterations resulting from stroke in a rat model to investigate the neuroprotective role of physical exercise. Forty male Wistar rats were assigned to 4 groups: a) control, b) ischemia, c) physical exercise, and d) physical ...

objective: spinal cord injury (sci) causes infertility in male patients through erectile dysfunction, ejaculatory dysfunction, semen and hormone abnormalities. oxidative stress (os) is involved in poor semen quality and subsequent infertility in males with sci. the aim of this study is to examine the effects of sci on the level of testosterone hormone. materials and methods: in this experimenta...

background stroke is the second cause of death and disability in the world, and oxidative stress which could be considered as a prognostic factor in patients for prevention, follow up and determination of stroke’s severity has a conceivable role in neural damage. objectives the aim of our study was to explain the association between oxidant/antioxidant imbalance as a prognostic factor in patien...

This study aimed to compare the antioxidant content and antioxidant capacity of pulp and peel of two varieties of pomelo fruit (Tambun White and Tambun Pink). Antioxidants including total phenolic content, total flavonoid content and ascorbic acid content were determined using Folin-Ciocalteu reagent assay, aluminium chloride colorimetric assay and AOAC method, respectively. Antioxidant capacit...

UNLABELLED BACKGROUND This study aims to determine the relationship between the antioxidant and anti-inflammatory activities of the thirteen herbs and two fungi extracts, and their total phenolic and flavonoid contents. METHODS Antioxidant activities were evaluated by four assays: an antioxidant activity assay using Saccharomyces cerevisiae, a DPPH ((2, 2-diphenyl-1-picrylhydrazyl) assay t...
