本文运用激光多普勒微循环血流计测定了336例正常人(平均年龄48岁,男232人,平均49岁,女104人,平均46岁)之舌尖、牙龈、口唇、左无名指指腹及甲襞之微区血流量。表明口唇部结果最稳定,变异系数最小,服从正态分布,而甲襞结果波动最大。认为口唇为测定体表微区血流量校为合适的部位。19例口唇或舌尖有阏斑 In this paper, 336 normal subjects (mean age 48 years old, 232 men, average 49 years old, 104 women, average 46 years old) were measured with laser Doppler microcirculation flowmeter. The tips of the tongue, gums, lips and left ring finger And nailfold micro-area blood flow. The results show that the lips of the most stable results, the smallest coefficient of variation, subject to normal distribution, and the maximum fluctuations in formazan results. That lips for the determination of surface micro-blood flow school as a suitable site. 19 cases of lips or tongue have swollen spots
