Role of sympathetic nerves in the vascular effects of local temperature in human forearm skin.

The role of adrenergic nerve function in the cutaneous vascular response to changes in local skin temperature in the human forearm was examined using three protocols: 1) blocking release of norepinephrine presynaptically by local iontophoresis of bretylium (BT), 2) altering background adrenergic tone by changing whole body skin temperature, and 3) blocking… (More)
