非胰岛素依赖型糖尿病(NIDDM)患者的足部浅溃疡发病率高。这种足部溃疡主要归咎于神经障碍所致的大血管损害程度较大的病变。微血管的舒张反应对损伤愈合过程可能有重要作用,但迄今在这类高危人群中作出诊断时仍未对整个舒张反应作过检测。激光多普勒流量检测仪可用于测量轻微热损伤时微血管的最大舒张(最大充血)反应。业已 Patients with non-insulin-dependent diabetes mellitus (NIDDM) have a high incidence of foot ulceration. This foot ulcer is mainly due to neurological disorders caused by a large degree of vascular damage. The vasorelaxation of the microvasculature may play an important role in the process of wound healing, but so far the overall diastolic response has not been tested in the diagnosis of these high-risk groups. The laser Doppler flowmeter can be used to measure the maximal diastolic (maximal hyperemic) response of capillaries at mild thermal injury. Already
