Prolonged vibration of cutaneous artery: absence of persisting aftereffects.

1-3 h after prolonged (3-16 h) vibration (120 Hz, 0.2-0.3 mm amplitude) of rings of canine saphenous arteries there was no significant change in the contractile response to electrical stimulation, exogenous norepinephrine or of neuronal uptake of tritium labeled norepinephrine. These results did not provide evidence for persistent aftereffects of prolonged vibration.
