background: spinal cord injury (sci) stimulates an inflammatory reaction that causes substantial secondary damage inside the injured spinal tissue. the purpose of this study was to determine the anti-inflammatory effects of epigallocatechin gallate (egcg) on traumatized spinal cord. methods: rats were randomly divided into four groups of 12 rats each as follow: sham-operated group, trauma group...

abstract   introduction: neurodegeneration change is one of the hallmark symptoms of which alzheimer’s disease (ad) can be modeled by β-amyloid injection into specific regions of brain. (-)-epigallocatechin-3-gallate (egcg) is a potent antioxidant agent that its role against oxidative stress and inflammation has been shown in prior studies. in the present study, we have wanted to determine whet...

Unorthodox (non-traditional or alternative) medicinal practices have been expanding very rapidly in western countries. Modern physicians, scientists, and non-traditional medicine practitioners now must join forces to promote evidence-based medicine to benefit patients. Green tea extracts are among the most widely used ancient medicinal agents, while androgens are probably the oldest drugs used ...

Determination of fl avan-3-ols as relevant to the matrix in foods, notably in one or more of the following matrixes: tea, wine, fruit and fruit juices, cocoa powder, chocolate, spices, and/or herbs. For the purpose of this SMPR, fl avan-3-ols (sometimes referred to as fl avanols) are the class of fl avonoids based on the 2-phenyl3,4-dihydro-2H-chromen-3-ol skeleton. Stereoisomers of fl avanol c...

BACKGROUND AND PURPOSE The polyphenolic compounds present in green tea show cancer chemopreventive effects in many animal tumor models. Epidemiologic studies have also suggested that green tea consumption might be effective in the prevention of certain human cancers. We investigated the effect of green tea polyphenols and the major constituent, epigallocatechin-3-gallate, on the induction of ap...

Although epidemiological studies indicate cancer preventive effects of diets rich in fruit and vegetables, large clinical intervention studies conducted to evaluate dietary supplementation with micronutrients, mostly vitamins, showed disappointing results in large parts. In contrast, there is encouraging epidemiologic data indicating great chemopreventive potential of a large group of phytochem...

Vascular endothelial growth factor (VEGF) receptors (VEGFR) play a major role in tumor angiogenesis and, thus, represent attractive targets for the development of novel anticancer therapeutics. In this work, we report that green tea catechins are novel inhibitors of VEGFR-2 activity. Physiological concentrations (0.01-1 microM) of epigallocatechin-3 gallate, catechin-3 gallate, and, to a lesser...

The purpose of this study was to assess the antibacterial efficacy of incorporating catechins into 4META/MMA-TBB resin against Streptococcus mutans and to measure the shear bond strength of a metal bracket bonded to enamel using catechin-incorporated with 5% 4-methacryloyloxyethyl trimellitate anhydride (4-META)/methyl methacrylate (MMA)-tri-n-butyl borane (TBB) resin (catechin-resin). Catechin...
