Xiao, H., JunFang, Lu, X., Liu, Z., Chen, X., Liu, J., Su, J., Yi, J. and Sun, Z. 2009. Protective effect of soluble fiber from Undaria pinnatifida on vascular endothelium in hypercholesterolemic rabbits. Can. J. Anim. Sci. 89: 361-367. Dietary fiber could improve endothelial function and abnormal production of nitric oxide (NO) and elevated endothelin-1 (ET-1) concentration induce endothelial dysfunction. In the present study, we tested the effect of soluble fiber extracted from Undaria pinnatifida (UP) on endothelial function and NO and ET-1 production in hypercholesterolemic rabbits. After ...
