通过对217名4—13岁健康儿童口唇粘膜微循环观察测定了各项正常值和加权积分值。男109名,女108名,按年龄分为10组。显微放大250倍测量3×1mm~2范围的均值。口唇微循环正常值;1.清晰度:管袢清晰194名,不清20名,模糊3名。2.管袢数:9.36±1.89条/mm~2。管袢数随年龄增长而递增(P<0.01)。3.管袢直 The normal and weighted integrated scores of 217 oral mucosal microcirculation of healthy children aged 4-13 years were determined. 109 men and 108 women, divided into 10 groups by age. Micro-magnification 250 times measuring 3 × 1mm ~ 2 range of mean. The normal value of the microcirculation of the lips; 1. Clarity: tube 袢 clear 194, unclear 20, fuzzy 3. Tube number: 9.36 ± 1.89 / mm ~ 2. Tube number increased with age (P <0.01). 3. Tube 袢 straight
