Green tea polyphenol epigallocatechin-3-gallate ameliorates insulin resistance in non-alcoholic fatty liver disease mice.

Aim: Epigallocatechin-3-gallate (EGCG) is a major polyphenol in green tea. In this study, we investigated the effects of EGCG on insulin resistance and insulin clearance in non-alcoholic fatty liver disease (NAFLD) mice.

Methods: Mice were fed on a high-fat diet for 24 weeks.

[Resveratrol protects against hydrogen peroxide induced injury in human umbilical vein endothelial cells].

Objective: To investigate the effect of Resveratrol on Hydrogen peroxide-treated human umbilical vein endothelial cells (HUVEC).

Methods: Oxidative stress in HUVEC was induced by hydrogen peroxide (H2O2). The cells were divided in to 5 groups: A.

Anti-inflammatory effect of soyasaponins through suppressing nitric oxide production in LPS-stimulated RAW 264.7 cells by attenuation of NF-κB-mediated nitric oxide synthase expression.

The anti-inflammatory properties of soyasaponins (especially soyasaponins with different chemical structures) have scarcely been investigated. We investigated the inhibitory effects of five structural types of soyasaponins (soyasaponin A(1), A(2), I and soyasapogenol A, B) on the induction of nitric oxide (NO) and inducible NO synthase (iNOS) in murine RAW 264.7 cells activated with lipopolysaccharide (LPS).
