1. The immunohistochemical results suggest that NPY-LI co-exists with NA in sympathetic
periarterial nerves of skeletal muscle. The corresponding veins are associated with few or …

Sympathetic nerve stimulation (2 min, 2 and 10 Hz) increased perfusion pressure in the
blood perfused canine gracilis muscle in situ after pretreatment with atropine, desipramine …

The effects of porcine neuropeptide Y (NPY) regarding sympathetic vascular control were
studied in vitro on isolated rat blood vessels. The 10‐9 M NPY enhanced (about two‐fold) …

BACKGROUND There is increasing evidence that neuropeptide Y (NPY) contributes to the
autonomic control of the circulation. NPY coexists with noradrenaline in perivascular nerve …

Neuropeptide Y (NPY)-immunoreactive nerve fibers were numerous around arteries and few
around veins. NPY probably co-exists with noradrenaline in such fibers since chemical or …

Neuropeptide Y (NPY) appears to be involved in the sympathetic regulation of vascular tone.
To assess the putative role of NPY in mesenteric circulation, the release and biological effect …

Vascular effects of neuropeptide Y (NPY) and noradrenaline (NA) were studied in six human
volunteers. Systemic infusion of human NPY for 40 min (5 pmol× kg−× min− 1) increased …

Neuropeptide Y (NPY), which co-exists with noradrenaline (NA) in postganglionic
sympathetic nerves, was able to potentiate NA-evoked constriction in certain isolated rabbit …

The mechanisms underlying the contractile effects of neuropeptide Y (NPY) in relation to
those of noradrenaline (NA) on small human blood vessels were studied in vitro. NPY …

The presence of neuropeptide Y (NPY)-like immunoreactivity (-LI) in sympathetic
perivascular nerves and the functional effects of NPY and noradrenaline (NA) on vascular …
