\r\n
\r\nIn the in vitro study, endothelial function in response to green and black teas was first assessed in bovine aortic endothelial cells and rat aortic rings.
\r\n
\r\nGreen and black tea were found to significantly increase endothelial NO synthase activity to the same extent in bovine aortic endothelial cells, and induce comparable endothelial-dependent vasodilation in rat aortic rings.
\r\n
\r\nIn the in vivo part of the study, endothelial-dependent vasodilation (flow-mediated dilation, FMD) and endothelial-independent vasodilation (nitro-mediated dilation, NMD) were assessed by ultrasound in 21 healthy women before and two hours after consumption of green and black tea, in comparison to control (water) in a crossover design.
\r\n
\r\nIntake of green and black tea led to significant increases in FMD, where the increase in FMD associated with green and black tea intakes did not significantly differ. NMD did not vary between any of the groups.
\r\n
\r\nThus, the results of this study suggest that consumption of green and black teas are equally effective in improving endothelial function.\r\n \r\n | \r\n \r\n \r\n \r\n \r\n <!-' + '- controls -' + '->\r\n \r\n \r\n \r\n  \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n <!-' + '- / controls -' + '->\r\n | \r\n
