Background: The aim of this study was to evaluate the vasodilatation and vasomotion response to local heating in the cutaneous microcirculation of the ankle, dorsum of foot and forearm. Recently, it has been suggested that this response differs between the forearm and the leg.

Probands And Methods: Twenty-nine young healthy adults were recruited.

In order to describe adequately the process of healing in the intermediate degrees, we investigated microcirculatory changes in the venous ulcers at well-defined stages of wound repair. We investigated dynamic changes in microcirculation during the healing process of venous ulcers. Ten venous ulcers were investigated in three consecutive clinical stages of wound healing: non granulation tissue (NGTA), GTA and scar.

To treat mixed skin ulcers effectively, it is important to investigate skin microcirculation in greater detail. Therefore, we used laser Doppler perfusion imaging and capillary microscopy for assessing both subpapillary and nutritive microcirculation in four defined regions of the skin in 17 patients with mixed ulcers caused by a combination of peripheral arterial occlusive disease and chronic venous insufficiency. Laser Doppler area flux was significantly higher in the ulcer areas than in the areas without granulation tissue and those in intact skin.
