Article history: Received on: 12/05/2013 Revised on: 19/10/2013 Accepted on: 07/12/2013 Available online: 31/12/2013 Food derived antioxidants have a strong potential for long term use as chemo-preventive agents in disease states involving oxidative stress such as tea. This study was done to clarify the potential effect of green tea extract in protecting the liver from lipopolysaccharide (LPS)-...

This study investigated the antioxidative activity of green tea extract, and a green tea tannin mixture and its components, under conditions of radical generation using the hydrophilic azo compound, 2,2'-azobis(2-amidinopropane) dihydrochloride (AAPH) to generate peroxyl radicals at a constant and measurable rate in the cultured renal epithelial cell line, LLC-PK(1), which is susceptible to oxi...

Background: Type 2 diabetes is a global health problem and a major cause of illness. Exercise, diet and medication are the three pillars in the treatment of type 2 diabetes. Objective: The aim of the present study was to investigate the effect of aerobic training combined with green tea hydroalcoholic extract consumption on blood glucose and lipid profile on diabetic rats. Methods: Diabetes ...

Background: Previous studies have reported controversial results for the association between green tea consumption and low-density lipoprotein (LDL)-cholesterol and body weight. Objective: The objective of this trial was to determine the effects of two kinds of green tea on LDL-cholesterol and body weight. Methods: We randomly assigned 151 participants (98 men, 53 women) aged 30-70 years into t...

Background: Recent studies indicate the important role of chronic inflammation and oxidative stress in the pathogenesis of hypertension. Green tea, due to the high content of catechins, shows high antioxidant activity. Objective: To determine the effect of supplementation with green tea extract on the blood pressure, on the concentration of selected parameters of inflammation and antioxidant st...

In the present study, it was try to investigate the effects of green tea on some biochemical parameters of male albino rats with ethanol toxicity. All rats were divided into 4groups, Group 1 (controls) and group 2 (ethanol control) remaining 2 groups were treated with ethanol and green tea extract for 30 days. The results showed significant elevation in the level of ACP, sugar (P<0.001), and Bi...

Background Many supplements on the market today contain ingredients that claim to increase metabolism and enhance fat loss. Green tea extract and caffeine have well known thermogenic properties. The purpose of this study was to evaluate the effects of proprietary thermogenic dietary supplement Dyma-Burn Xtreme, containing a blend of ingredients including caffeine, green tea extract, raspberry k...

Diabetes is one of the most common metabolic disorders and is interrelated to oxidative stress-induced diseases. According to the role of dietary antioxidants in control and prevention of diabetes, this study was aimed to evaluate the effect of green tea extract on serum glucose levels and serum and hepatic total antioxidant capacity (TAC) and lipid (MDA) in diabetic rats. Experimental diabetes...

Green tea has been shown to be a potent chemopreventive agent against lung tumorigenesis in animal models. Previously, we found that treatment of A/J mice with either green tea (0.6% in water) or a defined green tea catechin extract (polyphenon E; 2.0 g/kg in diet) inhibited lung tumor tumorigenesis. Here, we described expression profiling of lung tissues derived from these studies to determine...

BACKGROUND Recently, the anticarcinogenic effects of green tea have been studied in sites other than the urinary tract. The present study examined the inhibition by green tea of vesical tumors induced in rats by N-butyl-N-(4-hydroxybutyl) nitrosamine (BBN). METHODS In the first series of experiments, 0.05% BBN was added to the drinking water of rats and remained present for 5 weeks. In one ex...
