Outline of Final Research Achievements

Green tea catechin has an antioxidative effect and may improve endothelial function. The aim of the present study was to examine whether long-term treatment with green tea catechin improves endoterial function in human forearms. Forearm blood flow (FBF) was measured in nine healthy women, before and four weeks after oral treatment with green tea catechin (540 mg/day). The long-term treatment with green tea catechin did not alter FBF at rest or peak FBF during RH. However, green tea catechin treatment significantly improved total reactive hyperemic flow (flow debt repayment) (P < 0.01). These results indicate that long-term treatment with green tea catechin improves endothelium-dependent forearm vasodilations in healthy human.
