Abstract
Parkinson's disease (PD) in military personnel engaged in combat operations is likely to develop in their later lives. In order to enhance the quality of lives of PD patients, exploration of novel therapy based on new research strategies is highly warranted. The hallmarks of PD include increased alpha synuclein (ASNC) and phosphorylated tau (p-tau) in the cerebrospinal fluid (CSF) leading to brain pathology. In addition, there are evidences showing increased histaminergic nerve fibers in substantia niagra pars compacta (SNpc), striatum (STr), and caudate putamen (CP) associated with upregulation of histamine H3 receptors and downregulation of H4 receptors in human brain. Previous studies from our group showed that modulation of potent histaminergic H3 receptor inverse agonist BF-2549 or clobenpropit (CLBPT) partial histamine H4 agonist with H3 receptor antagonist induces neuroprotection in PD brain pathology. Recent studies show that PD also enhances amyloid beta peptide (AβP) depositions in brain. Keeping these views in consideration in this review, nanowired delivery of monoclonal antibodies to AβP together with ASNC and H3/H4 modulator drugs on PD brain pathology is discussed based on our own observations. Our investigation shows that TiO2 nanowired BF-2649 (1 mg/kg, i.p.) or CLBPT (1 mg/kg, i.p.) once daily for 1 week together with nanowired delivery of monoclonal antibodies (mAb) to AβP and ASNC induced superior neuroprotection in PD-induced brain pathology. These observations are the first to show the modulation of histaminergic receptors together with antibodies to AβP and ASNC induces superior neuroprotection in PD. These observations open new avenues for the development of novel drug therapies for clinical strategies in PD.

Abstract
A novel histamine receptor subtype, histamine H(3) receptor, mediates inhibition of peripheral autonomic neurotransmission. The present study was designed to examine vascular effects of histamine H(3) receptor by using a selective histamine H(3) receptor agonist, R-(-)-alpha methylhistamine (alpha-methylhistamine), in rat mesenteric resistance arteries. The isolated mesenteric vascular beds were perfused with Krebs solution and perfusion pressure was measured. Active tone was produced by perfusion of Krebs solution containing 7 microM methoxamine. In preparations with intact endothelium, perfusion of alpha-methylhistamine (1-100 microM) for 1 min produced a concentration-dependent vasodilation. The maximum vasodilation at the highest concentration was approximately 45%. This vasodilation was abolished by endothelium removal and attenuated by histamine H(3) receptor antagonists, thioperamide and clobenpropit, but not by chlorpheniramine (histamine H(1) receptor antagonist) and cimetidine (histamine H(2) receptor antagonist). N(omega)-nitro-L-arginine methyl ester (L-NAME, nitric oxide (NO) synthase inhibitor), indomethacin (cyclooxygenase inhibitor) and tetraethylammonium (nonselective K(+)-channel blocker) and high KCl (30 mM) significantly inhibited alpha-methylhistamine-induced endothelium-dependent vasodilation. These findings suggest that alpha-methylhistamine induces endothelium-dependent vasodilation mainly via endothelium histamine H(3) receptors. It is also suggested that activation of histamine H(3) receptors in the endothelium releases mainly NO and partially prostaglandin I(2) and endothelium-derived hyperpolarizing factors to induce endothelium-dependent vasodilation.

Abstract
Activation of histamine H3 receptors (H3Rs) reduces inflammation and nociception, but the existence of H3Rs on peripheral innervation has never been demonstrated. Here we use antibodies to locate H3Rs in whisker pads, hairy and glabrous hind paw skin, dorsal root ganglia (DRGs), and spinal cords of rats, wild type mice, and H3R knockout (H3KO) mice. Although H3Rs have been hypothesized to be on C and sympathetic fibers, H3R-like immunoreactivity (H3R-LI) was only detected on presumptive periarterial A delta fibers and on A beta fibers that terminated in Meissner's corpuscles and as lanceolate endings around hair follicles. The H3R-positive periarterial fibers were thin-caliber and coexpressed immunoreactivity for calcitonin gene-related peptide (CGRP), substance P, acid sensing ion channel 3, and 200 kDa neurofilament protein (NF). H3R-LI was also detected on epidermal keratinocytes and Merkel cells, but not on Merkel endings, C fibers, any other A delta fibers, or sympathetic fibers. In DRGs, H3R-LI was preponderantly on medium to large neurons coexpressing NF-LI and mostly CGRP-LI. In dorsal horn, CGRP-positive fibers with and without H3R-LI ramified extensively in lamina II; many of the former formed a plexus in lamina V. Low levels of H3R-LI were also present on A beta fibers penetrating superficial and into deeper laminae. The distribution of H3R-LI was similar in rats and wild type mice, but was eliminated or strongly reduced in A delta fibers and A beta fibers, respectively, in H3KO mice. Taken with recently published behavioral results, the present findings suggest that periarterial, peptidergic, H3R-containing A delta fibers may be sources of high threshold mechanical nociception.

Abstract
This study was designed to determine if the histamine H3 receptor agonist R-alpha-methylhistamine would play a role in modulation of sympathetically evoked mydriasis in anesthetized rats, and if so, to ascertain the specific receptor subtype(s) involved. Reproducible frequency-response curves of pupillary dilation were generated by stimulation of the cervical preganglionic sympathetic nerve (1-32 Hz). Systemic administration of R-alpha-methylhistamine (0.3-3.0 mg kg(-1)) produced a dose-related inhibition of the evoked mydriasis. The greatest inhibition was seen at lower frequency levels, with about 43% depression observed at 2 Hz. The specific histamine H3 receptor antagonist, clobenpropit (3.0 mg kg(-1), i.v.), blocked the inhibitory effect of R-alpha-methylhistamine, whereas neither the histamine H2 receptor antagonist, cimetidine (5.0 mg kg(-1), i.v.), nor the histamine H1 receptor antagonist, chlorpheniramine (0.5 mg kg(-1), i.v.), was effective. The histamine H2 receptor agonist, dimaprit (10 mg kg(-1), i.v.), was also without effect on the evoked mydriasis. R-alpha-methylhistamine (3.0 mg kg(-1)) did not inhibit phenylephrine-induced mydriasis. These results support the conclusion that R-alpha-methylhistamine produces inhibition of sympathetically evoked mydriasis via histamine H3 receptor stimulation, presumably by an action on presynaptic histamine H3 receptors.

Abstract
AIMS Histamine may contribute locally to cutaneous blood flow control under normal and pathologic conditions. The objective of this study was to observe the influence of skin temperature on histamine vasodilation, and the roles of H1-and H2-receptors using novel noninvasive methods. METHODS Eleven healthy subjects received, double-blind, single doses of the H1-receptor antagonist cetirizine (10 mg), cetirizine (10 mg) plus the H2-receptor antagonist cimetidine (400 mg), or placebo on separate occasions. Histamine was dosed cumulatively by iontophoresis to the forearm skin at 34 degrees C and 14 degrees C. Laser-Doppler flux (LDF) was measured at the same sites using customised probeholder/iontophoretic chambers with Peltier cooling elements. Finger mean arterial pressure (MAP) was measured and cutaneous vascular conductance calculated as LDF/MAP. RESULTS Histamine vasodilation was reduced in cold skin. Cetirizine shifted the histamine dose-response at both temperatures: statistically significantly at 14 degrees C only. Combined H1- and H2-receptor antagonism shifted the response significantly at both temperatures. CONCLUSIONS H1- and H2-receptors mediate histamine-induced skin vasodilation. The sensitivity of these receptors, particularly the H1- receptor, is attenuated at low skin temperature. Whether the reduced effect in cold skin represents specific receptor or postreceptor desensitization, or nonspecific attenuation of cutaneous vasodilation remains to be elucidated.

Abstract
Responses to the histamine H3 receptor agonist R-(-)-alpha-methyl-histamine were investigated in the mesenteric vascular bed of the cat under constant-flow conditions. Injections of R-(-)-alpha-methyl-histamine and histamine caused dose-related decreases in mesenteric perfusion pressure with R-(-)-alpha-methyl-histamine being 1000-fold less potent than histamine when doses were compared on a nmol basis to take molecular weight into account. Responses to R-(-)-alpha-methyl-histamine were not altered by histamine H1 or H2 receptor antagonists at a time when responses to histamine were significantly reduced. The histamine H3 receptor antagonist thioperamide reduced responses to R-(-)-alpha-methyl-histamine but was without effect on responses to histamine [6-[2-(4-imidazolyl)ethylamino]-N-(4-trifluoro-methylphenyl)heptaneca rdoxamide dimaleate] (HTMT), or dimaprit. These data suggest the presence of histamine H1, H2 and H3 receptors mediating vasodilation in the mesenteric vascular bed. Responses to R-(-)-alpha-methyl-histamine and histamine were reduced by the nitric oxide synthase inhibitor N(omega)-nitro-L-arginine methyl ester (L-NAME) but were not altered by the cyclooxygenase inhibitor meclofenamate, the alpha-adrenoceptor blocker phentolamine, or adrenergic nerve terminal depleting agent reserpine. The present data suggest that histamine H3 receptors mediating vasodilation are present in the mesenteric vascular bed and that responses are mediated by the release of nitric oxide but not vasodilator prostaglandins or an effect on the adrenergic nervous system. These results indicate that vasodilator responses to histamine involve the activation of histamine H1 and H2 receptors and the release of nitric oxide in the mesenteric vascular bed of the cat.
