Background & Aims: Para-Nonylphenol (p-NP) can cause oxidative stress through reducing the activity of scavenging enzymes. The aim of the present study was to investigate the effect of green tea extract, as an antioxidant, on testisin rats exposed to p-NP. Methods: In the present study, 24 Wistar rats with mean body weight of 215 ± 10 g were divided into 4 groups (n = 6)...

background: the current study tried to investigate the antioxidant and anti-bacterial effects of green tea and grape seed extract (with a volume of 2%) on durability of tilapia packed in polyethylene bags, which were kept in cool temperature of 4±1 °c. methods: prepared fish were divided into 3 batches: 2 batches were treated by dipping for 30 min in ethanolic of green tea extract (2% v/v) and ...

Tea extracts are used in many over-the-counter preparations claiming to promote weight loss. The rationale for this usage includes reports that green tea extract increases thermogenesis, and extracts of green and black tea and mulberry leaf inhibit the digestion/absorption of carbohydrate and fat. The investigators in this study tested the potential of increasing doses of a mixture of three ext...

OBJECTIVE To investigate the possible therapeutic or protective effects of green tea in diabetic rat's testicular tissue, either as a single agent, or together with vitamin E. METHODS The present study was carried out at the Faculty of Medicine, Gazi University, Ankara, Turkey from May to August 2011 for 10 weeks. Forty-eight adult male Wistar albino rats, weighting 250-300 g, were divided in...

OBJECTIVE The aim of the present study was to elucidate the possible biochemical improving effect in lipid metabolic that may result from continuous treatment with Green Tea extract in normal albino rats and those rendered hyperlipidemic by long term supplementation of fat-enriched diet. MATERIALS AND METHODS Fifty male albino rats aged six weeks with 200±10 g weight were randomly divided int...

background: the application of natural compounds including green tea extract (gte) in food and pharmaceutical industries is limited. encapsulation in nanoliposomes could be used as a delivery system to protect these compounds during processing and storage. objective: in this study encapsulation of green tea extract in nanoliposomes and evaluation of its antibacterial, antioxidant and prebiotic ...
