Intra-arterial injection of neuropeptide Y (NPY)(1.3–2.0 μg/kg) resulted in decreases of
pulpal blood flow by 37.7±5.7%(mean±SEM). The intra-arterial injection of d-myo-inositol-1 …

The purpose of this study was to investigate the functional involvement of sympathetic nerve
in the control of the microcirculation in the dental pulp with the aim of elucidation of the …

Neuropeptide Y (NPY) immunoreactivity (‐IR) was found to be present in perivascular
nerves in the cat dental pulp and oral mucosa. Many ganglion cells in the superior cervical …

A study was designed to investigate the effects of close intra-arterial infusion of antagonists
to the sensory neuropeptides calcitonin gene-related peptide and substance P, as well as …

In view of recent findings, classical nerve-released transmitters that modulate pulpal blood
flow share their roles with novel vasoactive peptides. Noradrenaline coexists with …

The effects of unilateral extramandibular inferior alveolar nerve injury on pulpal blood-flow
responses to electrical stimulation and iv injections of substance P (SP) in cat mandibular …

The effect of somatostatin on nerve‐induced vasodilatation and the release of substance P
(SP) was studied in the dental pulp of anesthetized cats. Changes in pulpal blood flow were …

Recent advances in immunohistochemistry have revealed the distribution of various
neuropeptides in several mammalian dental pulps. These neuropeptides are substance P …

In order to better understand the regulation of blood flow to tooth-related structures, the
patterns of VIP-and NPY-ergic innervations in the rat were examined. Nerve fibers showing …

In a previous study, it was concluded that the neuropeptides calcitonin gene-related peptide
(CGRP) and substance P are released during resting conditions in the (exposed) ferret …
