Pharmacological analysis of vasconstrictor responses to periarterial purinergic nerve stimulation.

Examines the monophasic vasoconstrictor responses to periarterial purinerguc nerve stimulation. Effects of rauwolscine on vasoconstrictor responses to periarterial electric nerve stimulation; Influence of the pulse trains at low frequency on the activation of purinergic components of sympathetic cotransmission; Role of alpha-adrenergic mechanism on the modulation of adenosine 5-triphosphate release.
