Abstract
The involvement of spinal release of histamine in the nociceptive behaviors induced by cholecystokinin-8 (CCK-8) was investigated in mice. Intrathecal (i.t.) injection of CCK-8 elicited the nociceptive behaviors consisting of biting and licking. The nociceptive behaviors induced by i.t. treatment with CCK-8 showed two bell-shaped patterns. The histamine H3 receptor antagonist significantly promoted the nociceptive behaviors induced by CCK-8 at doses of 1–100 fmol and 100 pmol. The nociceptive behaviors elicited by CCK-8 was inhibited by i.t. administration of the CCK-B receptor antagonist in a dose-dependent manner, but not by the CCK-A receptor antagonist. The nociceptive behaviors induced by CCK-8 were markedly suppressed by i.t. pretreatment with antiserum against histamine and were abolished in histidine decarboxylase-deleted gene mice. In histamine H1 receptor-deleted gene mice, the nociceptive behaviors induced at both 10 amol and 10 pmol of CCK-8 were not affected. The tachykinin neurokinin-1 (NK1) receptor antagonists inhibited CCK-8 (10 pmol)-induced nociceptive behaviors in a dose-dependent manner. CCK-8 (10 amol)-induced nociceptive behaviors was not antagonized by co-administration with the tachykinin NK1 receptor antagonists. The nociceptive behaviors elicited by CCK-8 were inhibited by i.t. administration of the antagonist for the N-methyl-D-aspartate (NMDA) receptor in a dose-dependent manner. Our results suggest that the nociceptive behaviors induced by i.t. administration of CCK-8 (10 pmol) are mediated through the spinal release of histamine and are elicited via activation of the tachykinin NK1 and NMDA receptors, whereas the nociceptive behaviors induced by i.t. administration of CCK-8 (10 amol) are mediated through the spinal release of histamine and elicited via NMDA receptor activation.

Abstract
AIMS Investigate the involvement of the histaminergic projections from tuberomammillary nucleus (TMN) to the spinal cord in the modulation of nociception and peripheral edema in a model of monoarthritis. MAIN METHODS Subacute monoarthritis was induced by an intraarticular injection of carrageenan followed by LPS 72 h later. Disability and joint edema were assessed at the 3rd hour after LPS and at every hour up to 6 h. KEY FINDINGS Intrathecal administration of histamine potentiated joint incapacitation and edema, while the H1R antagonist cetirizine decreased both. The H3R agonist immepip decreased both incapacitation and edema, while the H3R antagonist thioperamide had the opposite effect. The microinjection of glutamate into the ventral TMN (vTMN) caused an increase of incapacitation and articular edema, whereas the blockade of this nucleus by cobalt chloride inhibited both parameters. Intrathecal administration of cetirizine prevented the increase of incapacitation and joint edema caused by glutamate microinjection into the vTMN. Similarly, an intrathecal injection of the NKCC1 cotransporter inhibitor bumetanide prevented the effects of glutamate microinjection into the vTMN, whereas coadministration of histamine with bumetanide only inhibited the potentiation of joint edema. A microinjection of orexin B into the vTMN potentiated incapacitation and joint edema, while coadministration of the OX1/2 receptor antagonist almorexant with orexin B did not. SIGNIFICANCE These data support the notion that TMN participates in the modulation of a peripheral inflammatory process by means of histaminergic projections to the spinal cord, and the hypothalamus may trigger TMN activation by means of glutamate and orexin.

Abstract
The involvement of spinal release of histamine on nociceptive behaviors induced by spermine was examined in mice. Intrathecal spermine produced dose-dependent nociceptive behaviors, consisting of scratching, biting and licking. The nociceptive behaviors induced by spermine at 0.02 amol and 10 pmol were markedly suppressed by i.t. pretreatment with antiserum against histamine and were abolished in histidine decarboxylase-deficient mice. In histamine H1 receptor-deficient mice, the nociceptive behaviors induced by spermine were completely abolished after treatment with 0.02 amol of spermine and significantly suppressed after treatment with 10 pmol of spermine. The i.t. pretreatment with takykinin NK1 receptor antagonists eliminated the nociceptive behaviors induced by 0.02 amol of spermine, but did not affect the nociceptive behaviors induced by 10 pmol of spermine. On the other hand, the nociceptive behaviors induced by spermine at both 0.02 amol and 10 pmol were suppressed by i.t. pretreatment with antagonists for the NMDA receptor polyamine-binding site. The present results suggest that the nociceptive behaviors induced by i.t. administration of spermine are mediated through the spinal release of histamine and are elicited via activation of NMDA receptors.

Abstract
Histamine and opioid systems are involved in supraspinal modulation of pain. In this study, we investigated the effects of separate and combined microinjections of agonists and antagonists of histamine H1 and H2 and opioid receptors into the thalamic submedius (Sm) nucleus on the formalin-induced orofacial pain. Two guide cannulas were implanted into the right and left sides of the Sm in ketamine- and xylazine-anesthetized rats. Orofacial formalin pain was induced by subcutaneous injection of a diluted formalin solution (50 μl, 1.5%) into the vibrissa pad. Face rubbing durations were recorded at 3-min blocks for 45 min. Formalin produced a biphasic pain response (first phase: 0-3 min and second phase: 15-33 min). Separate and combined microinjections of histamine H1 and H2 receptor agonists, 2-pyridylethylamine (2-PEA) and dimaprit, respectively, and opioid receptor agonist, morphine, attenuated the second phase of pain. The analgesic effects induced by 2-PEA, dimaprit, and morphine were blocked by prior microinjections of fexofenadine (a histamine H1 receptor antagonist), famotidine (a histamine H2 receptor antagonist), and naloxone (an opioid receptor antagonist), respectively. Naloxone also prevented 2-PEA- and dimaprit-induced antinociception, and the analgesic effect induced by morphine was inhibited by fexofenadine and famotidine. These results showed the involvement of histamine H1 and H2 and opioid receptors in the Sm modulation of orofacial pain. Opioid receptor might be involved in analgesia induced by activation of histamine H1 and H2 receptors and vice versa.

Abstract
The aim of this study was to evaluate the analgesic as well as anti-inflammatory activities of the new pyrrolo[3,4-d]pyridazinone derivatives. Moreover, the present study attempted to assess some of the mechanisms involved in the pharmacological activity of these compounds. In the previous studies it was shown that these compounds were highly active in the phenylbenzoquinone-induced 'writhing syndrome' test and had much lower activity in the hot plate, which indicates that mainly peripheral mechanisms of analgesia are involved in their effects. In these extended studies the analgesic activity of two tested compounds (4c, 4f) was confirmed in some animal models of pain. The studied compounds showed a significant and dose-related antinociceptive effect in the models of pain induced by formalin, capsaicin and glutamic acid. Both compounds decreased the edema formation and one of them (4c) attenuated mechanical hyperalgesia in carrageenan-induced paw inflammation in rats. Furthermore, both compounds inhibited cell migration, plasma exudation and nociceptive reaction in zymosan A-induced mouse peritonitis. In the subsequent studies, including experiments on isolated organs (ileum, trachea, aorta), radioligand assays and biochemical tests, it was demonstrated that analgesic and anti-inflammatory effects of the investigated structures are largely due to their competitive antagonism for histamine H1 receptor. The influence on the level of cAMP in inflammatory cells (shown in RAW 264.7 macrophages) and subsequent inhibition of cytokine (TNFα, IL-1β) release can also be one of the important mechanisms of their action. Moreover some additional mechanisms may also be involved in the eventual analgesic effect of tested pyrrolo[3,4-d]pyridazinone derivatives.

Abstract
Besides histamine, substance P (SP) has been demonstrated to play a crucial role in pruritic skin diseases. Although antihistamines are frequently used for pruritic skin diseases, little is known concerning the effect on an SP-induced event such as mast cell degranulation and the upregulation of adhesion molecules or the nitric oxide (NO) synthesis in endothelial cells. Our aim was to study the effect of bepotastine besilate on SP-induced degranulation of rat basophillic leukemia (RBL-2H3) cells and expression of adhesion molecules and NO synthesis in human dermal microvascular endothelial cells (HMVECs). Bepotastine besilate significantly inhibited SP-induced degranulation of RBL-2H3 cells and NO synthesis in HMVECs. Bepotastine besilate significantly inhibited expression of adhesion molecules in HMVESs, while it failed to suppress SP-induced upregulation of the adhesion molecules in HMVECs. Therefore, bepotastine besilate is assumed to act favorably on SP-induced basophil degranulation and NO synthesis in HMVECs.

Abstract
Histamine has a key role in allergic inflammatory conditions. The inflammatory responses resulting from the liberation of histamine have long been thought to be mediated by the histamine H1 receptor, and H1-receptor antagonists--commonly known as antihistamines--have been used to treat allergies for many years. However, the importance of histamine in the pathology of conditions such as asthma and chronic pruritus may have been underestimated. Here, we review accumulating evidence suggesting that histamine indeed has roles in inflammation and immune function modulation in such diseases. In particular, the discovery of a fourth histamine receptor (H4) and its expression on numerous immune and inflammatory cells has prompted a re-evaluation of the actions of histamine, suggesting a new potential for H4-receptor antagonists and a possible synergy between H1 and H4-receptor antagonists in targeting various inflammatory conditions.

Abstract
When mice were scratched with brushes on their dorsal skins, they began to scratch themselves with their hind paws. Thus, self-scratching behaviour was induced in mice in response to skin-scratching stimulation. If the second skin-scratching stimulation was given within a few days, the induction of the second self-scratching behaviour was significantly suppressed compared with the first one. Thereafter, mice gradually recovered from this unresponsive state within a week. Thus, a transient unresponsive state of self-scratching behaviour is induced by skin-scratching stimulation. Pretreatment with a tachykinin receptor NK-1R antagonist L-703606 or capsaicin significantly suppressed self-scratching behaviour, while pretreatment with a neutral endopeptidase inhibitor phosphoramidon significantly enhanced it. Pretreatment with a calcitonin gene-related peptide (CGRP) receptor antagonist CGRP(8-37) did not affect the following self-scratching behaviour. From these results, it is suggested that substance P (SP) signalling through its receptor NK-1R at least in part mediates the induction of self-scratching behaviour. After skin-scratching stimulation, immunoreactivity of SP both in the peripheral nerve fibres and in the dorsal root ganglion (DRG) neurons was significantly decreased and was well-correlated with suppression of self-scratching behaviour. From these findings, it is suggested that the induction of unresponsive states of self-scratching behaviour may be at least in part caused by the depleted states of SP in peripheral nerve fibres and/or in DRG neurons. The induction of a transient unresponsive state after skin-scratching may possibly happen also in patients with pruritus. Thus, further studies to elucidate the precise mechanisms are required.

Abstract
The present study evaluated the effects of different histamine receptor agonists and antagonists on the nociceptive response in the mouse formalin test. Intracerebroventricular (20-40 microg/mouse i.c.v.) or subcutaneous (1-10 mg/kg s.c.) injection of HTMT (H(1) receptor agonist) elicited a dose-related hyperalgesia in the early and late phases. Conversely, intraperitoneal (20 and 30 mg/kg i.p.) injection of dexchlorpheniramine (H(1) receptor antagonist) was antinociceptive in both phases. At a dose ineffective per se, dexchlorpheniramine (10 mg/kg i.p.) antagonized the hyperalgesia induced by HTMT (40 mug/mouse i.c.v. or 10 mg/kg s.c.). Dimaprit (H(2) receptor agonist, 30 mg/kg i.p.) and ranitidine (H(2) receptor antagonist, 20 and 40 mg/kg i.p.) reduced the nociceptive responses in the early and late phases. No significant change in the antinociceptive activity was found following the combination of dimaprit (30 mg/kg i.p.) with ranitidine (10 mg/kg i.p.). The antinociceptive effect of dimaprit (30 mg/kg i.p.) was prevented by naloxone (5 mg/kg i.p.) in the early phase or by imetit (H(3) receptor agonist, 25 mg/kg i.p.) in both early and late phases. The histamine H(3) receptor agonist imetit was hyperalgesic following i.p. administration of 50 mg/kg. Imetit-induced hyperalgesia was completely prevented by treatment with a dose ineffective per se of thioperamide (H(3) receptor antagonist, 5 mg/kg i.p.). The results suggest that histamine H(1) and H(3) receptor activations increase sensitivity to nociceptive stimulus in the formalin test.

Abstract
Orexins are neuropeptides that are mostly expressed in the posterior and lateral hypothalamus, and related to the central control of appetite, arousal, and antinociception. Orexin neurons projected to the tuberomammillary nucleus and orexins may release histamine from the histamine neurons in this nucleus. Histamine is known to cause hypernociception. The roles of histamine H1 and H2 receptors in the orexin A-induced antinociception, however, have not been clarified yet. Here we studied the effects of histamine H1 and H2 receptors on orexin A-produced antinociception using histamine receptor knockout mice in four assays of nociception; the hot-plate, the tail-flick, the tail-pressure and the capsaicin tests. Furthermore we studied effects of histamine H1 and H2 receptor antagonists on orexin A-produced antinociception in C57BL/6 mice. The antinociceptive effects of i.c.v. orexin A were greater in histamine H1 receptor or H2 receptor knockout mice than in the wild-type mice in all four assays of pain. Furthermore, treatment of C57BL/6 mice with a combination of i.c.v. orexin A and d-chlorpheniramine (a histamine H1 receptor antagonist) or cimetidine (a histamine H2 receptor antagonist) showed a greater antinociception than i.c.v. orexin A alone in all four assays. These findings suggest the possibility that orexin A may activate H1 and H2 receptors in the supraspinal levels through the release of histamine from neurons, which might attenuate the antinociceptive effects of orexin A. Thus, the blocking of the histamine H1 or H2 receptor may produce antinociception and enhance the orexin A-induced antinociception.

Abstract
Intrathecal injection of histamine elicited behavioral responses consisting of scratching, biting and licking in conscious mice. To study the participation of histamine in pain perception, histidine decarboxylase knockout mice were examined for pain threshold by means of three different kinds of noxious stimuli: thermal nociception (hot-plate, tail-flick, and paw-withdrawal), mechanical nociception (tail-pressure), and chemical nociception (formalin test and capsaicin test). Mutant mice lacking histidine decarboxylase showed significantly fewer nociceptive responses to the hot-plate, tail-flick, paw-withdrawal, tail-pressure, formalin and capsaicin tests. Sensitivity to noxious stimuli in the histidine decarboxylase knockout mice was significantly lower when compared to the wild-type mice. The intrathecally-administered histamine (400 pmol) significantly shortened the latency in the histidine decarboxylase knockout mice, but not in the wild-type mice in tail-flick tests. Pyrilamine, a histamine H(1) receptor antagonist, but not ranitidine, a histamine H(2) receptor antagonist, produced inhibition of the induced behavioral responses in the tail-flick test when co-administered with histamine. Sendide, a tachykinin NK(1) receptor antagonist, inhibited histamine-induced nociceptive behavior in the histidine decarboxylase knockout mice. In contrast, the treatment with D-(-)-2 amino-5-phosponovaleric acid (D-APV), an N-methyl-D-aspartate (NMDA) receptor antagonist, did not prevent the induction of the behavioral responses by histamine. These studies substantiate the evidence that nociceptive behavior induced by intrathecal injection of histamine is largely mediated through tachykinin NK(1) and histamine H(1) receptors in the spinal cord.

A comparison of neurokinin 1 receptor knock-out (NK1−/−) and wildtype mice: exploratory behaviour and extracellular noradrenaline concentration in the cerebral cortex of anaesthetised subjects. Neuropharmacology 2005; 48:706-19. [PMID: 15814105 DOI: 10.1016/j.neuropharm.2004.12.016] [Citation(s) in RCA: 41] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2004] [Revised: 11/22/2004] [Accepted: 12/17/2004] [Indexed: 11/17/2022]
Abstract
In behavioural screens, mice lacking functional NK1 receptors (NK1-/-) resemble wildtypes (NK1+/+) that have been given an antianxiety/antidepressant drug. Most, if not all, antidepressants increase noradrenergic transmission in the brain. Here, we have used in vivo microdialysis to compare the concentrations of extracellular noradrenaline ('efflux') in the cerebral cortex of anaesthetised NK1-/- and NK1+/+ mice. The effects of systemic administration of the antidepressant, desipramine, with and without local infusion of the alpha(2)-adrenoceptor antagonist, RX821002, were also evaluated. Finally, we compared the effects of desipramine on behaviour of NK1+/+ and NK1-/- mice in an activity chamber and in a light/dark exploration box. Basal noradrenaline efflux was increased 2 to 4-fold in NK1-/- mice compared with NK1+/+ mice but there was no difference in the effects of desipramine. RX821002 increased noradrenaline efflux in all vehicle-injected mice but, in desipramine-pretreated mice, noradrenaline efflux was increased in NK1+/+ mice, only. All behaviours in the light/dark exploration box differed in the two genotypes. Furthermore, with the exception of 'grooming', the effects of desipramine on behaviour of NK1-/- mice could be explained by the effects of this antidepressant on locomotor activity. Finally, alpha(2)-adrenoceptors are possibly desensitised in NK1-/- mice. We have yet to establish whether this is a cause or a consequence of the increased noradrenaline efflux.

Involvement of the histaminergic system in the nociceptin-induced pain-related behaviors in the mouse spinal cord. Pain 2004; 112:171-82.

Abstract
Intrathecal (i.t.) injection of nociceptin elicited a behavioral response mainly consisting of biting and licking, which were eliminated by the i.t. co-administration of opioid receptor-like-1 (ORL-1) receptor antagonists. The behavioral response induced by nociceptin was characteristically similar to that by i.t.-administered histamine, and was attenuated by i.t. co-administration of the H1 receptor antagonists, but not by the H2 receptor antagonists, whereas the H3 receptor antagonist promoted the nociceptin-induced behavior. H1 receptor knockout (H1R-KO) mice did not show the nociceptin-induced nociceptive behavior, which was observed in wild-type mice. Pretreatment with a histamine antiserum or a histidine decarboxylase inhibitor resulted in a significant reduction of the response to nociceptin. The previous studies showed that NK1 receptor antagonists and a novel substance P (SP)-specific antagonist given i.t. could reduce the behavioral response to nociceptin and histamine. On the other hand, the nociceptive response induced by nociceptin, but not histamine, was completely attenuated by the i.t. co-administration of agonists for GABAA and GABAB receptors. In contrast, the antagonists for GABAA and GABAB receptors injected i.t. showed same nociceptive response with nociceptin and histamine, and their nociceptive responses were significantly blocked by the i.t. co-administration of the H1 receptor antagonists, but not H2 receptor antagonists or ORL-1 receptor antagonists. The present results suggest that the activation of the ORL-1 receptor by nociceptin may induce the disinhibition of histaminergic neuron and enhance the release of histamine, which subsequently acts on the H1 receptor located on the SP-containing neurons to produce the spinal cord-mediated nociceptive response.

Abstract
To study the participation of histamine H1- and H2-receptors in pain perception, H1 and H2 receptor knockout (KO) mice were examined for pain threshold by means of three kinds of nociceptive tasks. These included assays for thermal, mechanical, and chemical nociception. H1KO mice showed significantly fewer nociceptive responses to the hot-plate, tail-flick, tail-pressure, paw-withdrawal, formalin, capsaicin, and abdominal constriction tests. Sensitivity to noxious stimuli in H1KO mice was significantly decreased when compared to wild-type mice. The antinociceptive phenotypes of H2KO were relatively less prominent when compared to H1KO mice. We also examined the antinociceptive effects of intrathecally-, intracerebroventricularly-, and subcutaneously-administered morphine in H1KO and H2KO mice. In these nociceptive assays, the antinociceptive effects produced by morphine were more enhanced in both H1KO and H2KO mice. The effects of histamine H1- and H2-receptor antagonists on morphine-induced antinociception were studied in ICR mice. The intrathecal, intracerebroventricular and subcutaneous co-administrations of d-chlorpheniramine enhanced the effects of morphine in all nociceptive assays examined. In addition, intrathecal co-administrations of cimetidine enhanced the antinociception of morphine in the hot plate tests. These results suggest that existing H1 and H2 receptors play an inhibitory role in morphine-induced antinociception in the spinal and supra-spinal levels.
