The purpose of this study was to examine whether reflex effects of changes in whole body skin temperature (Tsk) on cutaneous vasculature are mediated through the vasoconstrictor or the active vasodilator arm of the sympathetic nervous system. In six subjects, reflex responses in forearm skin blood flow (SkBF) to changes in Tsk were monitored by laser-Doppler flowmetry. SkBF was monitored at a control site and at a 0.6-cm2 site where bretylium (BT) had been iontophoretically applied to abolish… CONTINUE READING
