... group) and 24 age- and gender-matched healthy controls (Control group) were enrolled. The increase in forearm SkBF (skin blood flow) caused by local heating to 41 °C (SkBF41), known to depend on endothelial NO production, was determined with laser Doppler imaging. SkBF41 was expressed as a percentage...

We used laser Doppler imaging to measure the forearm skin blood flow responses of seven healthy young males to iontophoretic delivery of two preparations of 20g/l of lignocaine hydrochloride, one containing the preservatives methylparaben...

Physiological elevation of plasma vasopressin in man results in a small reduction in skeletal muscle blood flow but the action on skin blood flow has not been reported. 2.

It has been shown in previous studies that skin blood flow in the human foot falls when the extremity is placed below heart level, owing to an increase in precapillary resistance that is probably mediated by a local sympathetic axon reflex or a myogenic...
