Abstract
I have been studying the functions of the histaminergic neuron system in the brain, the location and distribution of which we elucidated with antibody raised against L-histidine decarboxylase (a histamine-forming enzyme) as a marker in 1984. For this purpose, we used two methods employing (1) pharmacological agents like alpha-fluoromethylhistidine, an HDC inhibitor, and agonists and antagonists of H1, H2 and H3 receptors and (2) knockout mice of the HDC- and H1- and H2-receptor genes. In some cases, we used positron emission tomography (PET) of H1 receptors in living human brains. It turned out that histamine neurons are involved in many brain functions, and particularly, histamine is one of the neuron systems to keep awakefulness. Histamine also plays important roles in bioprotection against various noxious or unfavorable stimuli (convulsion, nociception, drug sensitization, ischemic lesions, stress and so on). Finally, I briefly described interesting phenotypes found in peripheral tissues of HDC-KO mice; the most striking finding is that mast cells in HDC-KO mice are fewer in number, smaller in size and less dense in granule density than those of wild type mice, indicating that histamine is related to the proliferation and differentiation of mast cells. In conclusion, histamine is important not only in the central and peripheral systems as studied so far but also may be related to some new functions that are now under investigation in our laboratories.

Abstract
To elucidate the role of histamine in the pathogenesis of post-ischemic reperfusion injury of tissues, the effect of diamine oxidase (DAO) was studied on the changes in renal functions induced by 30 min occlusion followed by reperfusion of the renal vessels of unilaterally nephrectomized rats. Kinetic analysis using radiolabeled albumin revealed that vascular permeability of the kidney increased markedly after reperfusion. Although the intensity of neutrophil-dependent chemiluminescence of the blood remained unchanged during the occlusion, it increased significantly after reperfusion. Histological examination revealed a marked degeneration of glomeruli and proximal tubules in the reperfused kidney. Transtubular transport of phenolsulfophthalein (PSP) decreased markedly after reperfusion with concomitant increase in plasma levels of creatinine. Intravenously administered DAO markedly inhibited the reperfusion-induced increase in vascular permeability, preserved the structure of the kidney and normalized the rate of clearance of PSP and creatinine. Combined use of diphenylhydramine and ranitidine also inhibited the reperfusion injury of the kidney. These results suggested that histamine and its receptors might play critical roles in post-ischemic reperfusion injury of the kidney.

Abstract
In portacaval-shunted rats, basal but not pentagastrin-stimulated acid secretion was higher than in sham-operated controls. The basal serum gastrin concentration was unchanged and the postprandial serum gastrin concentration lowered following portacaval shunt. Thus, gastrin is not responsible for the elevated basal acid secretion. The present study provides evidence that there is no trophic effect on the oxyntic mucosa as a whole and that there is no change in parietal cell-associated gastrin receptors after portacaval shunting. Interestingly, however, endocrine cells in the oxyntic mucosa (the histamine-containing ECL cells) proliferated greatly and the pentagastrin- and cholecystokinin octapeptide-induced activation of the histamine-forming enzyme, histidine decarboxylase, in these cells was much greater than in control rats. Analysis of the dose-response curves for the enzyme-activating effect of pentagastrin and cholecystokinin-octapeptide indicated that the D50 values for these two stimulants were not altered by shunting but that the maximal enzyme activation was greatly elevated. The enhanced enzyme activation can be partly, but not fully, explained by the fact that the ECL cells were increased in number. The enhanced response following portacaval shunt probably reflects also an increased number of gastrin receptors per ECL cell. The effect of portacaval shunting on gastric ECL cells can perhaps be explained by impaired degradation in the liver of intestinal substance(s) exerting a highly specific trophic effect on the ECL cells or, alternatively, causing an enrichment of gastrin receptors on these cells, thereby making them more sensitive to the trophic effect of gastrin. The ECL cell hyperplasia is manifest about 4 weeks after the shunting. A modified procedure for portacaval shunting which left the gastroduodenal vein (otherwise ligated) drained to the liver produced the same trophic effect as conventional portacaval shunt, suggesting an intestinal rather than gastroduodenal origin of the agent(s) responsible for the trophic action.

Abstract
Tritoqualine (TRQ), used clinically as an antiallergic drug, did not inhibit histidine decarboxylase activity (HDC, EC. 4.1.1.22.) partially purified from fetal rats and the enzymes prepared from mastocytoma P-815 cells. However, TRQ inhibited the histamine release from rat peritoneal mast cells induced by compound 48/80 and ATP. TRQ was also effective in inhibiting antigen-induced histamine release in rat mast cells sensitized actively or passively by the homologous anti-DNP-Ascaris antibody. Preincubation of cultured mastocytoma P-815 cells in a medium including TRQ inhibited non-cytotoxically the histamine release of mastocytoma cells induced by compound 48/80, and the effect of TRQ became more marked with lengthening of the culture period in the presence of TRQ. It was concluded from these results that one of the main actions of TRQ as an antiallergic drug was not the inhibitory action on HDC, but might be ascribed to its inhibitory effect on histamine release from mast cells.

Abstract
We examined the interrelationship between inhibition of aortic histamine synthesis through inhibition of aortic histidine decarboxylase and intra-aortic albumin accumulation in rats made diabetic by a jugular vein injection of 60 mg/kg of streptozotocin under ether anesthesia. Animals were held for 4 weeks following overt manifestation of diabetes. At the end of 3 weeks, at least six animals in each of the diabetic and non-diabetic groups received intra-peritoneal injections of alpha-hydrazinohistidine (25 mg/kg at 12 h) for the last 7 days. Aortic albumin accumulation was measured by quantification of aortic uptake of fluorescein isothiocyanate conjugated to rat serum albumin injected in the jugular vein 1 h before sacrifice. The aortic albumin mass transfer and flux rates of the diabetic group were more than 300% higher than that of the control group; alpha-hydrazinohistidine treated diabetic rats had aortic albumin mass transfer rates equivalent to control values. The aortic albumin content was nearly tenfold higher in untreated diabetic rats, but again treatment with alpha-hydrazinohistidine returned this to control values. These data offer strong support to the premise that accelerated aortic histamine synthesis, which occurs in experimental diabetes, is an important mediator of increased aortic macromolecule uptake, and as such, may be one component of the multitude of factors responsible for increased susceptibility of atherosclerosis among individuals having diabetes mellitus.

Abstract
(S)-alpha-Fluoromethylhistidine (alpha-FMH) is a Kcat or "suicide-substrate" inhibitor of partially purified mammalian histidine decarboxylase; i.e. the agent is converted enzymatically to a more active form which effects a time-dependent, irreversible inhibition. Incubation of a alpha-FMH[4-3H] with enzyme and pyridoxal phosphate resulted in an apparently irreversible labeling of protein, with no demonstratable formation of free-amine product, suggesting a very low to non-existent turnover ratio. alpha-FMH was accumulated in isolated mastocytoma cells and effected a time-dependent inhibition of the conversion histidine[3H]----histamine[3H], the latter product having a markedly different distribution between cells and medium than the pre-existing histamine pool. Inhibition of whole-body histidine decarboxylase activity, as specifically measured by alpha-methylhistidine-14COOH----14CO2, was also time dependent. Concomitant reduction in histamine levels was seen only in the rapidly turning-over pools of stomach and brain. However, over the course of 13 weeks of chronic treatment, depletion of the relatively inert mast-cell histamine pool(s) was seen as well.

Abstract
High levels of histidine decarboxylase activity were measured in rat basophilic leukemia cells grown in ascitic form in 4 week old WKY/N rats. The potent inhibition of this enzyme by brocresine and alpha-methylhistidine but not by alpha-methyl DOPA identified it as a specific histidine decarboxylase. Gel filtration and polyacrylamide gel electrophoresis revealed a molecular weight of 125,000 for the native enzyme, similar to that of fetal rat liver histidine decarboxylase. Using rat basophilic leukemia cells as starting material, histidine decarboxylase was purified extensively in a seven step procedure. Electrophoresis under denaturing conditions revealed that histidine decarboxylase is a dimeric protein consisting of two identical subunits with a molecular weight of 62,000. The results indicate that rat basophilic leukemia cells provide a new and rich source for the purification of histidine decarboxylase.

Abstract
A sensitive coupled assay for histidine decarboxylase has been developed. This method involved conversion of [3H]histidine into [3H]histamine by the enzyme sample, with methylation of this product in situ, catalysed by the enzyme histamine N-methyltransferase, to yield [3H]N-tele-methylhistamine. The radioactive product was separated from the substrate by (i) extraction into chloroform, (ii) ion-exchange chromatography and (iii) liquid cation-exchange extraction. The "no tissue" assay blank comprised 0.0007% of the substrate radioactivity. Sample material with a histidine decarboxylase activity of as little as 0.14 fmol/min/ml (measured at 1 microM histidine) gave double the blank value. More than 50 assays could be performed in one day. This assay was used to determine the in vivo changes in mouse brain histidine decarboxylase activity following irreversible inhibition with (+) alpha-fluoromethylhistidine (alpha-FMH). From the time course of recovery of enzyme activity the half-life of histidine decarboxylase in vivo was calculated to be 53 h.

Abstract
Histidine decarboxylases from the stomach and brain of adult rats were purified 380- and 160-fold, respectively, and their properties compared with those of the enzyme from whole bodies of fetal rats (7600-fold purification). The molecular weights (about 90,000) and the apparent Km values for L-histidine (3 X 10(-4) M) of the three enzymes were similar. The pI value of the fetal enzyme was 5.0, and that of the brain enzyme was 5.4. Histidine decarboxylase of the stomach showed two peaks of activity corresponding to those of the fetal and brain enzymes (pI's of 5.0 and 5.4) on isoelectric focusing. Anti-fetal-histidine decarboxylase antiserum inhibited the stomach and fetal enzymes extensively, but the brain enzyme only slightly. These results indicate that there are at least two types of histidine decarboxylase in rat tissue.

Abstract
Lecanoric acid analogues containing benzanilide structure inhibited histidine decarboxylase and arachidonic acid release from the cell membrane phospholipids induced by a tumour promoter, 12-O-tetradecanoylphorbol-13-acetate. But they did not inhibit cellular binding of phorbol-12,13-dibutylate. Lecanoric acid analogues also inhibited prostaglandin synthetase and delayed-type hypersensitivity responses against sheep red blood cells in mice. Thus, lecanoric acid analogues antagonized several enzymic and cellular effects of the tumour promoter.

Abstract
1. The effects of secretin, glucagon, cholecystokinin-pancreozymin (CCK-PZ), gastric inhibitory peptide (GIP), vasoactive intestinal peptide (VIP), somatostatin, neurotensin and enkephalin on basal, pentagastrin- and histamine-stimulated gastric acid secretion were investigated in the conscious fistula rat. 2. Glucagon and GIP were ineffective inhibitors of basal and pentagastrin-stimulated secretion. CCK-PZ stimulated acid secretion at a low dose level but at higher doses it inhibited both pentagastrin- and histamine-induced secretions. VIP was ineffective at low doses and at high doses its action was complicated by reflux of stimulated pancreatic and intestinal secretions into the stomach. Met-enkephalin inhibited histamine- but not pentagastrin-stimulated secretion. Neurotensin inhibited the response to pentagastrin but had no effect on histamine-stimulated secretion. Secretin and somatostatin were potent inhibitors of basal and pentagastrin-stimulated acid secretion with little or no effect on the response to histamine. 3. At doses completely inhibitory to pentagastrin-stimulated secretion secretin and somatostatin did not block the mobilization of gastric mucosal histamine by pentagastrin, although somatostatin caused partial competitive inhibition at lower doses of pentagastrin. Thus secretin and somatostatin inhibited pentagastrin-induced secretion neither by blocking gastric mucosal histamine mobilization nor by abolishing the direct action of histamine on the parietal cell -- findings which are inconsistent with the proposed role of histamine as the mediator of the action of gastrin on the parietal cell.

Abstract
The properties of the histamine-forming enzyme in human brain samples were studied utilizing a radiochromatographic procedure. The influence of postmortem conditions was checked with rat brains, and the results indicated that the enzyme activity is not altered in situ for a delay not exceeding 4 h at ambient temperature. Moreover, tissue blocks or homogenates can be stored at temperatures for up to 3 months with a good preservation of the enzyme activity. The data indicate that histamine synthesis in the human brain involves the "specific" histidine decarboxylase (HD, EC 4.1.1.22) and not the aromatic L-amino acid decarboxylase: (1) the optimum pH is 7.4 at 10(-6) M-L-histidine; (2) the apparent Km is about 3.10(-5) M; (3) it is inhibited by alpha-hydrazino histidine and brocresine but not affected by alpha-methyl DOPA. Moreover, a major portion of the enzyme is localized in a subcellular fraction containing nerve terminals and it shows an uneven regional distribution which parallels that observed in the brain of other mammalian species. Taken together these data strongly suggest that histamine could play a neurotransmitter role in the human brain.

Abstract
Effects of partial inhibition of aortic histamine formation on aortic albumin uptake and lipid deposition were examined in male, New Zealand white rabbits maintained on Purina Rabbit Chow containing 0.5% cholesterol for a 2-week period. Aortic histamine synthesis was inhibited by partial inhibition of aortic histidine decarboxylase (HD) through administration of alpha-hydrazinohistidine (alpha-HH, MK785, Regis Chemical Co., 25 mg/kg, i.p. at 12-h intervals). Additional rabbits were maintained on either the cholesterol diet or on Purina Rabbit Chow without cholesterol. Results indicate that administration of alpha-HH for the 2-week period produced a 31% reduction (P less than 0.05) in aortic HD activity in those rabbits maintained on the cholesterol diet, and that concurrently there was a 51% reduction in aorta albumin uptake (P less than 0.025) and a 63% reduction in the extent of oil red O staining. By regression analysis a significant correlation coefficient (r = 0.71, P less than 0.005) was obtained between the aortic albumin uptake and the aortic histamine forming capacity (HFC) in rabbits maintained on this cholesterol diet. These findings indicate that the aortic HD system may be an important enzymatic coupler involved in vascular permeability alterations occurring early in the atherogenic sequence.

Abstract
L-aromatic aminoacid decarboxylase has been purified more than thousand times from homogenates of rat brain, in several steps : centrifugation, DEAE-cellulose, CM cellulose, hydroxylapatite, DEAE sephadex. Its properties have been studied, most of them on an intermediate fraction of the purification, because of the instability of the purified enzyme in spite of the addition of different stabilizing agents : the enzyme decarboxylates 5-hydroxytryptophan (5 HTP) and DOPA in a ratio constant throughout the purification but does not decarboxylate tryptophan, tyrosine, histidine at a measurable rate. Optimum pH, Km, Vm, have been measured with 5 HTP and DOPA as substrates. The enzyme has a molecular weight of 115.000, an apparent isoelectric point of 6,4-6,5. It is inhibited by serotonin, dopamine, some cations : Cu++, Fe++, Ni++ by N-ethylmaleimide, sodium dodecylsulfate. Some pyridoxal-5 phosphate (PLP) remains strongly bound to the enzyme. For relatively weak concentrations of substrate, the enzyme is inhibited by an excess of PLP ; for weak concentrations of PLP, the enzyme in inhibited by an excess of substrate, particularly of DOPA. We also observe a spontaneous decarboxylation of the substrates that reaches a plateau and is enhanced by high concentrations of PLP, by serotonin, dopamine, Cu++ and reduced by mercaptoethanol and the presence of crude or boiled homogenates. Several possible explanations of the spontaneous decarboxylation and of the enzymic inhibitions by an excess of PLP and by the substrates are given.

Abstract
Histidine decarboxylase (EC 4.1.1.22) from a mouse mastocytoma has been purified by chromatography on charged and non-charged n-alkyl derivatives of agarose. The former was represented by the coupling product of CNBr-activated agarose and alkylmonoamines (alkylamino-agarose), the latter by the coupling of agarose and alkylglycidyl ehters (alkyl agarose). The choice of fractionation medium was restricted by the enzyme stability; excessively high ionic strength media could not be used. Under the conditions investigated, the best result was obtained with the non-charged ocytl agarose. The enzyme was adsorbed to this gel at a relatively high ionic strength, and on stepwise decrease in ionic stength of the eluting buffer it was desorbed with a total recovery of 80%. There was an approx. 10-fold increase in specific activity. The histidine decarboxylase, thus purified, retained 90-100% of its activity for 10 days or more at 6-8 degrees C. Some general comments on protein fractionation on charged and non-charged alkyl derivatives of agarose are given. The complexity of protein interaction with the charged alkyl derivatives is illustrated by experiments with a colored protein, phycoerythrin.

Abstract
Histamine content and histidine decarboxylase activity in cortex and hypothalamus, together with histamine content in peripheral nervous structures were examined in normal and electrically stressed guinea-pigs. A significant increase in histidine decarboxylase activity in hypothalamus and cortex together with concomitant decrease in histamine content in hypothalamus have been found. Electric shock causes also a decrease in histamine content in spinal cord, spinal ganglia, dorsal roots and sensory nerve. The function of histamine in nervous system is discussed.

Abstract
1. Histidine decarboxylase activity of rat stomach fluctuates depending upon the functional state of the stomach. This varying enzyme activity poses special problems in assessing the effectiveness of enzyme inhibitors. After vagal denervation gastric histidine decarboxylase is markedly activated and remains at a high, stable level, which is unaffected by the functional state of the stomach. Thus it appears that vagally denervated rats are well suited for studies on histidine decarboxylase inhibitors.2. In vivo, brocresine (NSD-1055) was found to be a more effective inhibitor of gastric DOPA decarboxylase than of gastric histidine decarboxylase. With the fairly high dose given (200 mg/kg) the inhibition of histidine decarboxylase was at most 75-85% and quite short-lasting. The DOPA decarboxylase activity, which was not affected by vagal denervation, was inhibited more than 95% by brocresine; this inhibition was longer-lasting.3. Cycloheximide, which probably lowers gastric histidine decarboxylase activity by inhibiting enzyme synthesis, was maximally effective at a dose level as low as 1 mg/kg. Gastric DOPA decarboxylase was not inhibited by cycloheximide. Vagotomized rats and control rats responded similarly.4. Combined treatment of vagally denervated rats with brocresine and cycloheximide resulted in a rapid and persistent reduction of the histidine decarboxylase activity. It is concluded that the failure of brocresine alone to induce a lasting inhibition of histidine decarboxylase is due to continuous, rapid synthesis of new enzyme.5. The calculated half-life of gastric histidine decarboxylase was 75 min in vagally denervated rats and 45 min in normal fasted rats. The results suggest that the increased enzyme activity after vagal denervation is caused by an increased rate of enzyme synthesis.

Abstract
Histamine content of rat brain was lowered quickly by inhibitors of histidine decarboxylase, suggesting that a portion of brain histamine turns over rapidly. Restraint and exposure to cold also reduced brain histamine levels and markedly augmented its formation in the hypothalamus.
