摘要
目的:探讨冷刺激过程中大学生甲襞微循环的动态变化。方法:应用显微电视录像技术和激光多普勒血流仪,观察大学生冷刺激过程中甲襞微循环及微区血流量的动态变化。结果:甲襞冷刺激后较实验前微循环流态变慢,管襻形态、血液流态和总积分值均增大,微区血流量减少,并随冷刺激时间的延长,变化更为明显。结论:冷刺激可造成甲襞微循环障碍。
Objective：To study the effect of cold stimulation on the nailfold microcirculation and microbloodflow in college students.Methods：The changes in nailfold microcirculation and microlocalblood flow were studied by a vital microscope with TV recorder and leser Doppler flowmetry in 25 minutes after cold stimulation.Results：The volume of loop morphology scores,blood flour condition scores and total multiple scores all were increased,the blood condition slowed,and the volume of micro-local blood flow were decreased after cold stimulation.The microcirculatory changes were aggravated gradually as time went on.Conclusion：The cold stimulation can lead to the disfunction of the nailfold microcirculation.
