Abstract
Sweating has been associated with the exacerbation of atopic dermatitis (AD) in diverse ways. Acetylcholine (ACh)-mediated sweating is known to be attenuated in AD, but its cause remains obscure. To address this issue, the impact of histamine on ACh-induced sweating was evaluated. Sweating was measured by counting the number of active sweat pores by the starch-iodine reaction and dynamic optical coherence tomography; sweat was visualized using two-photon excitation fluorescence microscopy in mice and the quantitative sudomotor axon reflex test in humans. Both histamine receptor antagonists and H1 receptor (H1R)-knockout (KO) mice were used to determine methodological specificity. Histamine demonstrably inhibited ACh-induced sweating in both mice and humans via H1R-mediated signaling. In sweat glands, ACh inactivated glycogen synthase kinase 3β (GSK3β), a kinase involved in endocytosis and secretion, whereas simultaneous stimulation with histamine activated GSK3β. Results of two-photon excitation fluorescence microscopy confirmed the dynamic motion of sweat and sweat glands after ACh treatment, showing that simultaneous stimulation with histamine altered their dynamic properties. These results indicate that histamine inhibits sweat gland secretions by blocking ACh-induced inactivation of GSK3β. Histamine-mediated hypohidrosis might be involved in the mechanism of abnormal skin dryness in patients with AD.

Abstract
[(3)H]Cimetidine (3HCIM) specifically binds to an unidentified site in the rat brain. Because recently described ligands for this site have pharmacological activity, 3HCIM binding was characterized. 3HCIM binding was saturable, heat-labile, and distinct from the histamine H(2) receptor. To test the hypothesis that 3HCIM binds to a cytochrome P450 (P450), the effects of nonselective and isoform-selective P450 inhibitors were studied. The heme inhibitor KCN and the nonselective P450 inhibitor metyrapone both produced complete, concentration-dependent inhibition of 3HCIM binding (K(i) = 1.3 mM and 11.9 muM, respectively). Binding was largely unaffected by inhibitors of CYP1A2, 2B6, 2C8, 2C9, 2D6, 2E1, and 19A1 but was eliminated by inhibitors of CYP2C19 (tranylcypromine) and CYP3A4 (ketoconazole). Synthesis and testing of CC11 [4(5)-(benzylthiomethyl)-1H-imidazole] and CC12 [4(5)-((4-iodobenzyl)-thiomethyl)-1H-imidazole] confirmed both drugs to be high-affinity inhibitors of 3HCIM binding. On recombinant human P450s, CC12 was a potent inhibitor of CYP2B6 (IC(50) = 11.7 nM), CYP2C19 (51.4 nM), and CYP19A1 (140.7 nM) and had a range of activities (100-494 nM) on nine other isoforms. Although the 3HCIM binding site pharmacologically resembles some P450s, eight recombinant human P450s and three recombinant rat P450s did not exhibit 3HCIM binding. Inhibition by KCN and metyrapone suggests that 3HCIM binds to a heme-containing brain protein (possibly a P450). However, results with selective P450 inhibitors, recombinant P450 isoforms, and a P450 antibody did not identify a 3HCIM-binding P450 isoform. Finally, CC12 is a new, potent inhibitor of CYP2B6 and CYP2C19 that may be a valuable tool for P450 research.

Abstract
BACKGROUND Vascular endothelial growth factor (VEGF) exerts cytoprotective, antiapoptotic and proangiogenic effects; its synthesis is induced by hypoxia, several cytokines and histamine. The effects of histamine and the H2 receptor antagonist ranitidine on renal VEGF and IL-6 synthesis were investigated in a well-established rat model of renal ischemia/reperfusion injury. METHODS Following 7 days of pretreatment with histamine (H group; n = 12), ranitidine (R group; n = 10) or vehicle (controls; n = 13), the left vascular pedicle was clamped for 50 min in uninephrectomized male rats and survival assessed in the different treatment groups. Additionally, renal IL-6 mRNA expression, as well as VEGF mRNA and protein abundance were measured in the three treatment groups following pretreatment only, 2 and 16 h after 50 min of renal ischemia (n = 6/group/timepoint). RESULTS Ranitidine significantly increased, while histamine significantly decreased survival following renal ischemia. Renal IL-6 mRNA expression increased 2 h after reperfusion in all groups and decreased thereafter, with the lowest level observed in the R group. While VEGF mRNA did not change in controls, histamine increased, whereas ranitidine decreased its expression during the follow-up. Two hours after ischemia a twofold increase in renal VEGF protein abundance was observed in controls and the H group and significantly higher values were noted in the R group at this time point. A further increase in VEGF protein was only present in the H group 16 h after reperfusion. CONCLUSION These results indicate an important role of histamine in kidney damage following renal ischemia. The beneficial effects of ranitidine were partly mediated by decreased IL-6 and VEGF mRNA expression and significant early increase in renal VEGF abundance.

Abstract
A total of 260 male and female adult (60-70 days of age) and weanling (22-25 days of age) Sprague-Dawley derived rats were used in these experiments. Subcutaneous administration of histamine (HA) elicited drinking in a dose-dependent manner for both ages tested, although the threshold dose varied with age. A dose of 5.0 mg/kg HA elicited significant increases in water intake for adults, whereas for weanlings a dose of 20 mg/kg HA was necessary. Adult rats exhibited decreased latency to drink after all doses of HA tested, whereas for weanlings, decreased latency was evident only after doses of HA sufficient to elicit increases in water intake. Combined antagonism of H1 and H2 receptors for HA, using dexbrompheniramine and cimetidine, respectively, inhibited HA-elicited drinking in adults and weanlings. Further investigation of the ontogeny of histamine- and food-related drinking may provide a useful approach to examine the physiological mechanisms underlying fluid consumption in adult animals and as they are gradually elaborated during ontogeny.

Abstract
The effects of histamine H1- and H2-receptor antagonists on histamine-stimulated renin secretion were examined in anesthetized dogs. Tripelennamine (H1 blocker) further enhanced renin secretion in the presence of exogenous histamine. Moreover, tripelennamine alone increased renin secretion. These effects are probably due to non-specific properties of the drug and not to interaction of tripelennamine with H1 receptors. Conversely, cimetidine (H2 blocker) significantly inhibited histamine-induced increases in renin secretion, renal blood flow, and sodium excretion without any changes in mean arterial blood pressure or glomerular filtration rate. Cimetidine alone had no effect. We conclude that H2 receptors mediate the effect of histamine on renin secretion in dogs with innervated, intact kidneys.

Abstract
Histamine influences the glomerular microcirculation and modulates immune-inflammatory responses. In the rat kidney, histamine is synthesized by glomeruli and stimulates cyclic nucleotide production specifically in glomeruli. We investigated the in vitro effect of histamine on cyclic nucleotide accumulation in rat cultured glomerular mesangial and epithelial cells. Histamine stimulated cyclic AMP (cAMP) accumulation in cultured mesangial cells (64.0 +/- 22.1 to 511.4 +/- 86.6 pmol/mg protein, n = 9) but had no effect on cAMP accumulation in epithelial cells. This effect was dose-dependent and time-dependent. Stimulation of cAMP accumulation occurred in the range of 5 X 10(-6) M-10(-4) M histamine with a half maximal stimulatory effect of 2 X 10(-5) M. Initial stimulation was noted by 30 s, and maximum stimulation was observed at 5 min. The H2 antagonist cimetidine (10(-4) M) abolished the stimulatory effect of histamine (10(-4) M), while equimolar concentrations of the H1 antagonist diphenhydramine had no significant effect on cAMP accumulation. Moreover, the specific H2 agonist dimaprit, but not the H1 agonist 2-pyridylethylamine, stimulated cAMP accumulation. Histamine had no effect on cAMP accumulation in epithelial cells or on cyclic guanosine monophosphate accumulation in epithelial or mesangial cells. Since the in vivo infusion of histamine reduces ultrafiltration coefficient and since mesangial cell contraction is thought to be responsible for the reduction in the ultrafiltration coefficient, we examined the effect of histamine on the contractile property of mesangial cells. Histamine (5 X 10(-6)-10(-4) M) contracted mesangial cells, and the H1 antagonist diphenhydramine (10(-4) M) but not the H2 antagonist cimetidine (10(-4) M) prevented histamine (10(-4) M) induced contraction. In addition, the H1 agonist 2-pyridylethylamine, but not the H2 agonist dimaprit, contracted mesangial cells. Histamine and its specific agonists and antagonists induced contraction of isolated glomeruli as assessed by glomerular planar surface area in a manner parallel to their effect on mesangial cells. Cinnarizine (10(-5) M), a Ca++ channel blocker, or Ca++, Mg++-free medium prevented histamine (10(-4) M) induced mesangial cell and glomerular contraction. Thus, histamine enhances cAMP accumulation specifically in mesangial cells via an H2 receptor. In contrast, histamine contracts mesangial cells and glomeruli via an H1 receptor, an effect that is dependent on extracellular Ca++ entry. These findings show that histamine potentially influences intraglomerular hemodynamics via effects on mesangial cell contraction. Moreover, our findings considered with the in vivo observation that histamine reduces kf via and H1 receptor provide further support of the hypothesis that mesangial cell contraction regulates the glomerular capillary surface area available for filtration. Our studies also show that this contractile effect of histamine is dependent on extracellular calcium. The presence of a cAMP system sensitive to histamine may have major implications in the pathogenesis of inflammatory glomerulopathies. Mesangial cells possess characteristics similar to circulating and tissue immune effector cells, including lysosomal enzyme release, oxygen radical production, and release of a number of immunomodulatory factors. Histamine and cAMP have been shown to modulate such characteristics of inflammatory cells. It is therefore conceivable that histamine, via its interaction with H2 receptors and subsequent generation cAMP, may have profound effects on such properties of mesangial cells, suggesting that this autacoid may modulate not only glomerular hemodynamics but also immune, inflammatory responses within the glomerulus.

Abstract
The effects of histamine on cAMP and cGMP accumulation and the intrarenal metabolism of histamine were studied in glomeruli and cortical tubules of nine human kidneys. Histamine stimulated cAMP but not cGMP accumulation in glomeruli (delta + 100% to + 265%) in a dose- (10(-6) to 10(-4) M range) and time-dependent manner. This effect of histamine was inhibited by the histamine H2 antagonist cimetidine but not the H1 antagonist diphenhydramine. Moreover, the H2 agonist dimaprit but not the H1 agonist 2-pyridylethylamine stimulated cAMP accumulation. Histamine had no effect on cAMP or cGMP accumulation in tubules. Because the content of histamine (congruent to 2 X 10(-6) M) in glomeruli was far above the circulating levels of plasma histamine in humans (less than 10(-8) M), we explored whether histamine is formed in human renal tissue. Incubation of glomeruli with 1 mM of the histamine precursor L-histidine resulted in an increase in histamine levels (+ delta 6.08 +/- 0.5 pmoles/mg protein, N = 7 kidneys) while a marked drop in histamine levels was observed in tubules (- delta 13.8 +/- 2.4 pmoles/mg protein, N = 7 kidneys). The increase in histamine levels in glomeruli was abolished by the histidine decarboxylase inhibitor bromocresine. These results indicate that human glomeruli have histamine H2 receptors, which mediate enhanced cAMP accumulation, and that glomeruli are major sites of histamine production in the human kidney. Histamine acting via cAMP may influence glomerular function of the human kidney.

Abstract
The H2-antagonist cimetidine is widely employed in biochemical and pharmacological studies of the H2-receptor. These studies include the use of 3H-cimetidine in radioligand binding experiments. Confirming our previous finding as to the unsuitability of this ligand in these types of investigations, we now report data showing the lack of correlation between the displacement of specific 3H-cimetidine binding and histamine stimulated adenylate cyclase activity, and the displacement of specific binding by imidazoles devoid of H2-receptor activity. Results are also presented which question the use of copper ions in 3H-cimetidine binding studies. Our conclusions are discussed in relation to the work carried out by a number of laboratories where 3H-cimetidine is reported to label the H2-receptor.

Abstract
1 The effect of intrarenal histamine, dimaprit (H2-agonist) and 2-(2-pyridyl) ethylamine (H1-agonist) on renin release was examined in anaesthetized dogs. 2 In dogs with intact kidneys, histamine and dimaprit administration resulted in renal vasodilatation, a two fold increase in urinary sodium excretion, and no change in renal renin release. 2(2-Pyridyl) ethylamine administration resulted in renal vasodilatation, a 25% decrease in urinary sodium excretion and a significant increase in renin release. 3 In dogs with non-filtering kidneys, dimaprit administration resulted in renal vasodilatation and a significant increase in renin release, while 2(2-pyridyl) ethylamine administration resulted in renal vasodilatation but no change in renin release. 4 Our data suggest that histamine is a potential participant in the release of renin through stimulation of H2-receptors, but it is a weak agonist. 5 In addition, the direct effect of histamine analogues on renin release is modulated by their effects on electrolyte excretion probably by influencing the renal chemoreceptor release of renin mediated by the macula densa.

Abstract
The antagonist-sensitive binding of [3H]mepyramine to beef aortic membranes was as expected for binding to histamine H1-receptors. [3H]mepyramine binds rapidly and in saturable fashion to the specific receptor sites, specific binding reaching equilibrium in 3 min at 37 degrees C. SCATCHARD's analysis of the binding data gave a dissociation constant of 3.0 nM for the radioligand-receptor complex and maximal number of binding sites: 31 fmol/mg protein. In the competition studies histamine H1-antagonists are more potent inhibitors of radioligand binding than H2-antagonist. They inhibit [3H]mepyramine binding in the following order: mepyramine greater than triprolidine greater than promethazine much greater than cimetidine. Binding data are in correlation with the previous pharmacological studies.
