| Research Abstract |
The object of this study was to clarify the prophylaxis effect of small peptides on vascular-related diseases. As a result, peptides having basic amino acids could evoke a significant vasorelaxation effect in contracted rat aorta. The effect was closely associated with the reduction of intracellular Ca2+ through a Ca2+ channel. In addition, a 9-wk administration of WH to apo E deficient mice successfully improved a significant atherosclerosis area.
