The effects of pressure on the luminal surface of the rabbit aorta were investigated using the scanning electron microscope. The method followed was perfusion under hydrostatic pressure of a section of thoracic aorta, in vitro. The characteristic ridged pattern seen in sections fixed at zero hydrostatic pressure was to a large extent eliminated when fixation occurred at pressures equivalent to those experienced by the aorta at systole or diastole. This study suggests that the spiral ridged pattern is dependent upon the fixation pressure and may not be present in a normally functioning artery. Any attempts to characterize or interpret the appearance of the luminal arterial wall must take into account the effects of pressure.
使用扫描电子显微镜研究了压力对兔主动脉管腔表面的影响。采用的方法是在体外对一段胸主动脉进行静水压力灌注。在零静水压力下固定的切片中所见的特征性脊状图案，在相当于主动脉在收缩期或舒张期所承受压力的条件下固定时，在很大程度上被消除了。这项研究表明，螺旋状脊状图案取决于固定压力，在正常功能的动脉中可能不存在。任何试图表征或解释动脉管腔壁外观的尝试都必须考虑压力的影响。
