1. A non-invasive method is described for the assessment of angiogenesis in chronic inflammation using laser-Doppler flowmetry.
2. Significant increases in capillary blood flow were seen on days 5 and 7 after induction of subcutaneous granulomatous lesions, as compared with control skin.
3. Changes in blood flow were accompanied by changes in pulsatile flow pattern and by an intense angiogenic response observed by light microscopy.
4. The potential application of laser-Doppler flowmetry to quantitative and qualitative studies of evolving angiogenesis in pathological responses is discussed.
