Publisher Summary The finding by Lundberg et al. that neuropeptide Y (NPY) is present in a
large population of nerve cell bodies in the sympathetic ganglia was the first indication that …

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 …

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 …

Neuropeptide Y co-exists with noradrenaline in the majority of the sympathetic nerves
supplying cerebral blood vessels. However, after sympathectomy in the rat the number of …

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

1 Neuropeptide Y (NPY) has recently been reported to coexist with noradrenaline (NA) in
central as well as peripheral noradrenergic nerves. NPY‐containing nerve fibres are …

During intense sympathetic activation, as occurs during hemorrhage, veins constrict to a
greater degree than do arteries. This study determined if differences in the amounts or …

1 The contractile effect of neuropeptide Y (NPY) was tested on isolated segments of basilar
artery, central ear artery, gastro‐epiploic artery and vein, and femoral artery and vein from …

Neuropeptide Y (NPY) is a powerful vasoconstrictor in vivo but is usually much less active
on isolated blood vessels. The contractile effect of NPY was examined in the isolated rat …

Contraction of the guinea pig saphenous artery induced by stimulation of perivascular
nerves consists of an adrenergic and a purinergic component. Neuropeptide Y (NPY) …
