【摘要】 八十年代以来 ,关于血管壁零应力状态的研究已有很多文献报道 ,但目前尚不清楚血管壁各组成成分对其零应力状态展开角的贡献。本文研究中 ,以弹性蛋白酶、胶原蛋白酶、细胞松驰素D和秋水仙素分别作用于血管壁 ,从其保留组份零应力状态展开角的变化来分析血管壁各组份对其零应力状态展开角的贡献 ,这在血管壁零应力状态研究工作中是很有意义的。更多还原

【Abstract】 There were plenty literature reports focusing on the zero stress state of blood vessels since 1980s, but it was not clear about the role of vascular component to contribution the opening angle of blood vessel at zero stress state. We investigated the opening angle of aorta at zero stress state after the vessels were respectively digested by collagenase and elastinase, and the microtube and microfibril of the vascular smooth muscle cells were inhibited by cytochalasin D and colchicine. We could then analyze the contribution of aortic component to opening angle from the experimental results. It was necessary to the study on vascular zero stress state.更多还原
