目的:采用原子力显微镜对动脉内壁表面超微结构进行在位成像,并分析血管收缩及扩张时微纳尺度形貌变化,以明确其生理作用机制。方法:本研究用原子力显微镜的磁驱动轻敲模式对麻醉大白兔腹主动脉进行在位成像。
OBJECTIVE: To study the in-situ imaging of the ultrastructure of the arterial wall by atomic force microscopy and to analyze the changes of the micro-and nano-scale topography during the contraction and expansion of vasoconstriction to clarify the physiological mechanism. Methods: In this study, magnetic resonance imaging of the abdominal aorta of anesthetized rabbits was performed in magnetic-activated tapping mode.
