Measurements of human skin capillary blood cell velocity (CBV) were performed by videophotometric capillaroscopy using a crosscorrelation technique. Mean resting (r) CBV in a group of 64 healthy subjects (age 20-82; 33 men) was 0.60 +/- 0.51 (SD) mm/s at a skin temperature of 30.9 +/- 3.2 degrees C. Skin temperature, but not rCBV, was significantly higher in the men. rCBV showed a weak positive correlation with skin temperature with a marked increase of high rCBV values when skin temperature was more than 31 degrees C. During the postocclusive reactive hyperemia (PRH) after a one-minute arterial occlusion, CBV reached a maximal velocity of 1.17 +/- 0.66 mm/s at 7.8 +/- 2.4 s after cuff release. This PRH response was reproducible with regard to peak velocity (pCBV) and the time to pCBV. The percentage increase of CBV during PRH was inversely correlated to skin temperature (r = -0.69). The results of the present study are proposed as a basis for further studies of human skin capillary circulation in health and disease.
采用互相关技术的视频光度毛细管显微镜法对人体皮肤毛细血管血细胞速度（CBV）进行了测量。在一组64名健康受试者（年龄20 - 82岁；33名男性）中，在皮肤温度为30.9±3.2℃时，静息（r）CBV平均值为0.60±0.51（标准差）mm/s。男性的皮肤温度显著高于女性，但rCBV无显著差异。rCBV与皮肤温度呈弱正相关，当皮肤温度超过31℃时，高rCBV值显著增加。在一分钟动脉闭塞后的闭塞后反应性充血（PRH）期间，袖带松开后7.8±2.4秒时，CBV达到最大速度1.17±0.66 mm/s。这种PRH反应在峰值速度（pCBV）和达到pCBV的时间方面具有可重复性。PRH期间CBV的增加百分比与皮肤温度呈负相关（r = -0.69）。本研究结果为进一步研究健康和疾病状态下人体皮肤毛细血管循环奠定了基础。
