Abstract
Curcumin, derived from the rhizome Curcuma longa, has been scientifically proven to possess anti-inflammatory activity but is of limited clinical and veterinary use owing to its low bioavailability and poor solubility. Hence, analogs of curcuminoids with improved biological properties have been synthesized to overcome these limitations. This study aims to provide the pharmacological basis for the use of 5-(3,4-dihydroxyphenyl)-3-hydroxy-1-(2-hydroxyphenyl)penta-2,4-dien-1-one (DHHPD), a synthetic curcuminoid analog, as an anti-edematogenic and anti-granuloma agent. The carrageenan-induced paw edema and the cotton pellet-induced granuloma assays were used to assess the anti-inflammatory activity of DHHPD in mice. The effects of DHHPD on the histaminergic, serotonergic, and bradykininergic systems were determined by the histamine-, serotonin-, and bradykinin-induced paw edema tests, respectively. DHHPD (0.1, 0.3, 1, and 3 mg/kg, intraperitoneal) evoked significant reductions (p < 0.05) in carrageenan-induced paw edema at different time intervals and granuloma formation (p < 0.0001) by 22.08, 32.57, 37.20, and 49.25%, respectively. Furthermore, DHHPD significantly reduced paw edema (p < 0.05) induced by histamine, serotonin, and bradykinin. The present study suggests that DHHPD exerts anti-edematogenic activity, possibly by inhibiting the synthesis or release of autacoid mediators of inflammation through the histaminergic, serotonergic, and bradykininergic systems. The anti-granuloma effect may be attributed to the suppression of transudative, exudative, and proliferative activities associated with inflammation.

Abstract
Bradykinin and related kinins may act on two types of receptors designated as B1 and B2. It seems that the B2 receptors are most commonly found in various vascular and non-vascular smooth muscles, whereas B1 receptors are formed in vitro during trauma, and injury, and are found in bone tissues. These bradykinin (BK) receptors are involved in the regulation of various physiological and pathological processes. The mode of kinin actions are based upon the interactions between the kinin and their specific receptors, which can lead to activation of several second-messenger systems. Recently, numerous BK receptor antagonists have been synthesized with prime aim to treat diseases caused by excessive kinin production. These diseases are rheumatoid arthritis (RA), inflammatory diseases of the bowel, asthma, rhinitis and sore throat, allergic reactions, pain, inflammatory skin disorders, endotoxic and anaphylactic shock and coronary heart diseases. On the other hand, BK receptor antagonists could be contraindicated in hypertension, since these drugs may antagonize the antihypertensive therapy and/ or may trigger the hypertensive crisis. It is worth suggesting that the BK receptor agonists might be useful antihypertensive drugs.

Abstract
BACKGROUND/AIM In periodontitis, bacteria and pathogen-associated molecular patterns are sensed by Toll-like receptors (TLRs), which initiate intracellular signaling cascades that may lead to host inflammation. In this study, the expression and distribution of TLRs (TLR-1 to TLR-10) were immunohistochemically detected in gingival epithelium and connective tissue. METHODS Immunohistochemistry was used for the localization of TLRs in gingival tissue samples from 10 patients with chronic periodontitis and 10 healthy controls; these samples were obtained during routine periodontal flap operations and during extraction operations performed for retained wisdom teeth, respectively. For the evaluation, epithelial layers were stratified to basal, spinous, and superficial layers, and the percentages of TLR-positive cells were determined. RESULTS Both healthy and periodontitis gingival tissues expressed all TLRs except TLR-10. In patients with periodontitis, epithelial cells showed increased TLR expression towards the basal layer. Healthy controls showed more variable cellular TLR expression and distribution between the layers of epithelium. In the connective tissue, consistently higher TLR expression was found within the periodontitis group compared to the healthy group. CONCLUSIONS For the first time, the cellular expression and distribution of TLR-1 to TLR-10 have been studied in periodontitis, indicating that TLR-1 to TLR-9 are differentially expressed both in connective tissue and epithelial layers. Except for TLR-7 and TLR-8, all the other TLRs showed statistically significant differences between patients with periodontitis and healthy controls, suggesting their involvement in the pathogenesis of periodontitis.

Abstract
BACKGROUND AND OBJECTIVE A dramatic difference in the frequencies of the Lys/Arg single nucleotide polymorphism in the lactoferrin genotype between a small population of patients with localized juvenile periodontitis and healthy subjects has been reported. As the single nucleotide polymorphism could be associated with ethnicity, the present study aimed to investigate the association between polymorphisms of the lactoferrin gene and periodontitis. MATERIAL AND METHODS Sixty-five patients with aggressive periodontitis, 278 with chronic periodontitis and 88 healthy controls were genotyped for the Lys/Arg polymorphism of the lactoferrin gene at position 29 [reference sequence (rs) 1126478] in the N-terminal alpha-helical region. RESULTS The frequencies of the GG genotype and the G allele were highest in the aggressive periodontitis group, followed by the chronic periodontitis group and then the healthy controls. The frequency of the G allele was significantly higher in aggressive periodontitis and chronic periodontitis groups than in healthy controls (p = 0.0037 and 0.0212). Although the difference of the GG genotype distribution between subjects with chronic periodontitis and healthy controls did not reach significance, the distribution of genotypes between aggressive periodontitis and healthy controls was significantly different. The association of the gene polymorphism and aggressive periodontitis still existed, even after adjusting for age, gender and smoking status by logistic regression analysis (GG/AG+AA: odds ratio = 2.16, 95% confidence interval = 1.09-4.35, p = 0.0287). After the study, subjects were further stratified by their smoking status; the GG genotype was still significantly associated with the risk of aggressive periodontitis in the nonsmoking group (odds ratio = 2.69, p = 0.018). However, there were no statistical differences between chronic periodontitis vs. healthy controls and aggressive periodontitis vs. healthy controls in the smoking group. CONCLUSION The present study revealed that the A/G polymorphism in the lactoferrin gene might be associated with aggressive periodontitis. The A allele might reduce the risk of development of aggressive periodontitis in a Taiwanese population. Our results also support the hypothesis that lactoferrin genetic polymorphisms could play a role in the risk for periodontitis separate from the smoking factor. The functionality of this gene's polymorphisms has to be further elucidated.

Abstract
AIM To review the association between genetic variability and the inflammatory response induced by periodontal infection. MATERIAL AND METHODS A search of MEDLINE-PubMed was performed from January 2000 up to and including March 2005. The search included all types of publications, published in English without other limitations. The following search terms were used: "cytokine polymorphism", "gene polymorphism", "periodontitis", "gingivitis", "inflammation" and "host-response". The papers resulting from the above search were used as an additional source for relevant articles. RESULTS Genetic variability was examined for the correlation to clinical indicators of inflammation such as bleeding on probing (BOP), gingival inflammation, cytokine in gingival crevicular fluid (GCF) and cytokine production by inflammatory cells. According to the current literature, most of the studies found no association between genetic variability and BOP, gingival inflammation or cytokine concentrations in the GCF. These studies were hampered by inappropriate study designs and the use of inflammatory parameters as secondary rather than primary outcome variables. The data suggest that the production of inflammatory mediators by inflammatory cells may be affected by different genetic traits but further studies are needed in order to establish this association. CONCLUSIONS To date, there is no clear correlation between any of the gene polymorphisms and clinical indicators of inflammation. The powering of studies to reveal associations between single or multiple nucleotide polymorphisms and inflammatory parameters will need to involve a much larger number of subjects than were used in the past. The available data (including the interleukin-1 composite genotype) do not currently support the utility of such tests in the diagnosis and prognostic assessments of periodontal diseases.

Abstract
In general, prostaglandin E1 (PGE1) is thought to relax smooth muscles in the airway and to inhibit muscle constriction. We hypothesized that, under the specific conditions, PGE1 induces bronchoconstriction, resulting in the promotion of inflammation. Examples of the specific conditions where this mechanism may occur include cases where patient who are susceptible to inflammation receive a continuous infusion of PGE1 during induced hypotension or during treatment for intraoperatively abnormal hypertension.

Abstract
The discovery of endogenous molecules involved in counterregulation of inflammatory responses that may lead to tissue injury provides an opportunity to explore new therapeutic approaches based on manipulation of new pathways. Natural counterregulatory pathways may reduce the possibility of unwanted toxic side-effects. Lipoxins are trihydroxytetraene-containing eicosanoids that are generated within the vascular lumen during platelet-leukocyte interactions and at mucosal surfaces via leukocyte-epithelial cell interactions. During cell-cell interactions, transcellular biosynthetic pathways are the major lipoxin biosynthetic routes, and thus, in humans, lipoxins are formed in vivo during multicellular responses, such as inflammation and asthma. This branch of the eicosanoid cascade generates specific tetraene-containing products that serve as "stop signals" for neutrophils that regulate key steps in leukocyte trafficking and prevent neutrophil-mediated tissue injury. These novel anti-inflammatory lipid mediators also appear to facilitate the resolution of the acute inflammatory response. In this review, recent findings and new concepts pertaining to the generation of lipoxins and their impact on the resolution of acute inflammation, and organ protection from leukocyte-mediated injury, are presented. The parallels and possible associations with periodontal diseases are discussed.

Abstract
The kinin family are a group of bioactive peptides that are closely involved in the modulation of vascular inflammation and local injury. We have demonstrated here, for the first time, a link between kinin activity and contact lens wear. Protein extracts from daily and extended wear etafilcon A, Group IV, Acuvue lenses (Vistakon), were analysed by counter immunoelectrophoresis. In this way, kinin activity associated with contact lens wear was detected. High molecular weight kininogen was used as the marker protein. In contrast, no kinin activity was detected in the non-lens wearing normal eye.

Abstract
Oligonucleotide DNA microarrays were used for a genome-wide analysis of immune-challenged Drosophila infected with Gram-positive or Gram-negative bacteria, or with fungi. Aside from the expression of an established set of immune defense genes, a significant number of previously unseen immune-induced genes were found. Genes of particular interest include corin- and Stubble-like genes, both of which have a type II transmembrane domain; easter- and snake-like genes, which may fulfil the roles of easter and snake in the Toll pathway; and a masquerade-like gene, potentially involved in enzyme regulation. The microarray data has also helped to greatly reduce the number of target genes in large gene groups, such as the proteases, helping to direct the choices for future mutant studies. Many of the up-regulated genes fit into the current conceptual framework of host defense, whereas others, including the substantial number of genes with unknown functions, offer new avenues for research.

Abstract
Putative binding sites for prokallikrein, the endogenous zymogen of the vasoactive and pro-inflammatory tissue kallikrein-kinin system, were recently demonstrated on human neutrophils. However, the occurrence and distribution of neutrophil-bound prokallikrein itself have so far not been examined. In this study, a specific anti-peptide antibody directed against the propart of the zymogen was used to localize the kallikrein precursor by confocal laser-scanning microscopy on unstimulated human blood neutrophils. Our results describe, for the first time, the presence of tissue prokallikrein on the membrane of circulating neutrophils. Immunoreactive prokallikrein was associated into punctate clusters occupying the external surface of the neutrophil membrane and, after addition of exogenous zymogen, immunolabeling was enhanced four-fold. In contrast, only moderate immunoreactivity to prokallikrein was observed intracellularly. These results suggest that resting neutrophils provide a circulating platform for tissue prokallikrein whose surface density may be upregulated as part of the inflammatory process.

Abstract
The main purpose of this paper is to study the possible causes of blood-brain barrier (BBB) damage during the acute condition of schizophrenia (Sch), which makes brain antigens accessible to the immunocompetent cells. The development of autoimmune reactions in this disease has to be preceded by the damage of BBB. We have studied the level of activity of plasma kallikrein-kinin (KKS) and complement systems, C-reactive protein (CRP) concentration, proteinase inhibitory potential as well as the oxidized and degranulating activity of neutrophils as the main factors affected the permeability of tissue-blood barrier. Our results suggested that the acute stage of Sch was accompanied by the activation of KKS on the background of enhance in the functional activity of the alpha-1-proteinase inhibitor. The increased level of CRP, the high haemolytic activity of complement and significant degranulating activity of polymorphonuclear leukocytes testified to inflammatory character of Sch. The treatment with psychotropic drugs have led to decrease of polymorphonuclear elastase (PMN-E) activity in patient's plasma. Our in vitro study indicates that Haloperidol causes the lowering of PMN-E activity in the dose-dependent fashion.

Abstract
Crinum asiaticum Linn plant is used in Malaysia as a rheumatic remedy and to relieve local pain. In the present study, we examined the anti-inflammatory effects of this plant extract on carrageenan-induced hind paw oedema in mice. C. asiaticum was serially extracted with petroleum ether, followed by chloroform and lastly, methanol. The chloroform and methanol extracts of the plant given orally (50 mg kg-1) caused significant (p < 0.05; n = 7) reduction in paw oedema but the petroleum ether extract did not induce significant effect (p > 0.05) on paw oedema. The methanol extract was then dissolved in water and extracted consecutively with chloroform, ethyl acetate and butanol. The chloroform fraction of methanol extract (CFME) treatment (50 mg kg(-1)) significantly reduced (p < 0.05; n = 7) the acute paw oedema. This may indicate that active anti-inflammatory compounds are present in the CFME. In an attempt to study the mechanism of action of its anti-inflammatory activity, the effects of CFME on BK- and histamine-induced contractions were investigated in isolated rat uterus and guinea-pig ileum preparations, respectively. It was found that CFME caused dose-dependent reduction (p < 0.05; n = 6) of the contractile response induced by BK and shifted the log dose-response curve of histamine to the right. The present findings suggest that C. asiaticum possessed an anti-inflammatory activity as suggested by its use in traditional medicine. The anti-inflammatory activity of this plant could not have been due to its anti-bradykinin activities as CFME non-specifically inhibited BK-induced contraction. It also suggest that CFME may contain compound(s) with anti-histaminic properties. The significance of these findings is discussed.

Abstract
Components of the kallikrein-kinin system are activated in response to noxious stimuli (chemical, physical or bacterial), which may lead to excessive release of kinins in the synovial joints that may produce inflammatory joint disease. The inflammatory changes observed in synovial tissue may be due to activation of B(2) receptors. Kinins also stimulate the synthesis of other pro-inflammatory agents (PGs, LTs, histamine, EDRF, PGI(2) and PAF) in the inflamed joint. B(2)-receptor antagonists may provide valuable agents as new analgesic drugs. Furthermore, it is suggested that substances to reduce activation of the kallikrein-kinin system (KKS) may provide a pharmacological basis for the synthesis of novel antirheumatic or anti-inflammatory drugs.

Abstract
The present study aimed to evaluate the effect of Hoe 140, a BK receptor B(2) antagonist, on acute oedema induced by carrageenan, BK and kaolin in male Wistar Kyoto rats. Hoe 140 (0.2 mg/kg and 20 mg/kg) given ip caused significant (p<0.05 and p<0.01) inhibition of carrageenan and BK-induced paw oedema. This suggests that BK is the prime inflammatory mediator of carrageenan oedema, and that it is also a specific blocker of oedema caused by BK. Furthermore, Hoe 140 was found to be less effective in reducing kaolin-induced oedema in rats. This might reflect that BK is not a prime inflammatory mediator of kaolin-induced oedema. The possible significance of these findings is discussed.

Abstract
Partial and full thickness burns with intervening zones of stasis were created on the backs on New Zealand White rabbits (n = 23). Either saline or the bradykinin receptor antagonist, NPC 17731, was administered. Skin blood flow was measured hourly using a laser Doppler blood flowmeter. After 4 h skin samples were harvested for assessment of tissue oedema (wet/dry weights) and leucocyte accumulation (immunohistochemistry). Statistical analysis was performed using Analysis of variance (ANOVA) and Mann-Whitney U test with a level of significance at P < 0.05. It was found that blood flow was decreased postburn in all groups. Bradykinin antagonist resulted in increased blood flow in partial thickness burns and zones of stasis compared to saline-treated animals (P < 0.05). Pretreatment with bradykinin antagonist showed reduced tissue oedema in full thickness burns (P < 0.05). No significant difference was observed in leucocyte accumulation between both groups. These data suggest a role for bradykinin in the pathogenesis of postburn microvascular changes which is independent of leucocyte-mediated injury.

Abstract
1. This study examines the effect of Hoe 140, a bradykinin (BK) 2 receptor antagonist, indomethacin and prednisolone on chronic adjuvant arthritis of the knee in rats. We also evaluated the influence of Hoe 140 on BK-forming enzymes in the synovial and paw tissues. 2. Adjuvant arthritis was induced in male Sprague-Dawley rats in the right knee by injecting 0.05 ml of a fine suspension of heat-killed Mycobacterium tubercle bacilli in liquid paraffin (5 mg/ml). 3. Hoe 140 (1.5 mg/kg i.p.), indomethacin (2.5 mg/kg orally) and prednisolone (3.0 mg/kg orally) administration for 9 days resulted in significant suppression of knee joint swelling. Plasma and tissue kallikrein levels were raised (P < 0.01) in the synovial and paw tissues of adjuvant arthritic rats. Hoe 140 treatment reduced (P < 0.05) tissue kallikrein but increased (P < 0.01) plasma kallikrein levels in synovial tissue. 4. Hoe 140 treatment did not alter (P > 0.05) the raised plasma and tissue kallikrein levels in the paw tissue. The findings indicate that Hoe 140 may be a useful anti-inflammatory agent and BK plays a major role in this adjuvant-induced arthritis model.

Abstract
A distinguishing feature of inflammatory bowel disease (IBD) is its apparently spontaneous, chronic relapsing course. Despite extensive research over several decades the etiology of IBD remains unknown, but evidence has accumulated to suggest that the mucosal inflammatory response may be caused by (i) a defective mucosal barrier function resulting in an abnormally increased exposure to luminal antigens and toxins, (ii) an appropriate immunologic response to an unusual infection, antigen or toxin, or (iii) an inappropriate immunological response to ubiquitous antigens or stimuli. In recent years, the identification of established and potential mediators of inflammation has expanded to include eicosanoids, platelet activating factor, biogenic amines, kinins, complement-derived peptides, chemotactic peptides, cytokines, neuropeptides, and reactive metabolites of oxygen and nitrogen. Thus, the study of the inflammatory process has become ever more complex. Until the predisposing and trigger factors have been identified the achievement of a more rational and effective approach to therapy in IBD relies on interruption of the mechanisms responsible for excess mediator formation. As summarized in this review on the role of soluble mediators of inflammation, several Danish gastroenterologists have been profoundly engaged in basic and clinical research in the past 25 years to place some pieces of the confusing puzzle of IBD.

Abstract
In the last decade a considerable amount of research has been dedicated to studying the process of angiogenesis. In the field of tumor biology angiogenesis is a relevant subject of investigation as well, since newly formed blood vessels are required for the growth of tumors and provide an exit route for metastasizing tumor cells. In this review we discuss some aspects of tumor angiogenesis with emphasis on the role that growth factors bFGF and VPF play in this process. A number of biochemical characteristics and biological properties of the two factors and their receptors are reviewed, and the expression of bFGF and VPF in both normal tissues and in tumors is discussed. Finally, we speculate on the use of bFGF and VPF expression as a diagnostic parameter and on possible clinical applications.

Abstract
Excessive release of kinin (BK) in the synovial fluid can produce oedema, pain and loss of functions due to activation of B1 and B2 kinin receptors. Activation of the kinin forming system could be mediated via injury, trauma, coagulation pathways (Hageman factor and thrombin) and immune complexes. The activated B1 and B2 receptors might cause release of other powerful non-cytokine and cytokine mediators of inflammation, e.g., PGE2, PGI2, LTs, histamine, PAF, IL-1 and TNF, derived mainly from polymorphonuclear leukocytes, macrophages, endothelial cells and synovial tissue. These mediators are capable of inducing bone and cartilage damage, hypertrophic synovitis, vessel proliferation, inflammatory cell migration and, possibly, angiogenesis in pannus formation. These pathological changes, however, are not yet defined in the human model of chronic inflammation. The role of kinins and their interacting inflammatory mediators would soon start to clarify the detailed questions they revealed in clinical and experimental models of chronic inflammatory diseases. Several B1 and B2 receptor antagonists are being synthesized in an attempt to study the molecular functions of kinins in inflammatory processes, such as rheumatoid arthritis, periodontitis, inflammatory diseases of the gut and osteomyelitis. Future development of specific potent and stable B1 and B2 receptor antagonists or combined B1 and B2 antagonists with y-IFN might serve as a pharmacological basis for more effective treatment of joint inflammatory and related diseases.

Abstract
1. Bradykinin and related kinins may act on four types of receptors designated as B1, B2, B3 and B4. It seems that the B2 receptors are most commonly found in various vascular and non-vascular smooth muscles, whereas B1 receptors are formed in vitro during trauma, and injury, and are found in bone tissues. 2. These BK receptors are involved in the regulations of various physiological and pathological processes. 3. The mode of kinin actions are based upon the interactions between the kinin and their specific receptors, which can lead to activation of several second-messenger systems. 4. Recently, numerous BK receptors antagonists have been synthesized with prime aim to treat diseases caused by excessive kinin production. 5. These diseases are RA, inflammatory diseases of the bowel, asthma, rhinitis and sore throat, allergic reactions, pain, inflammatory skin disorders, endotoxin and anaphylactic shock and coronary heart diseases. 6. On the other hand, BK receptor antagonists could be contraindicated in hypertension, since these drugs may antagonize the antihypertensive therapy and/or may trigger the hypertensive crisis. 7. It is worth suggesting that the BK receptor agonists might be useful antihypertensive drugs.

Abstract
A peptide cleaved from the link-protein component of human and pig proteoglycan aggregates by trypsin and stromelysin was taken up and degraded further by human monocytes, B cells, chondrocytes and by mouse peritoneal macrophages. Monocytes were able to process the peptide twice as rapidly as peritoneal macrophages and some 16 times more rapidly than articular chondrocytes. The B cell line Priess, which unlike the monocytes and macrophages could not take up or degrade whole proteoglycan aggregates, was able to degrade the peptide at a rapid rate. Synthetic, unglycosylated peptides consisting of the first 16 and 13 N-terminal amino acids of human link protein, corresponding to its stromelysin-cleavage and trypsin-cleavage products, were also taken up and degraded in a similar manner to the natural products and, in addition, were able to block uptake of the 125I-labelled natural peptides. The isoelectric points of the re-secreted breakdown fragment from both the synthetic and natural peptides were identical and each peptide was processed by the cells to produce a single radiolabelled fragment. Each of these fragments was eluted with the same retention time during HPLC, indicating that the natural peptides were derived from the N-terminal region of the link. Since a proportion of the link protein extracted from human and pig cartilage has already undergone proteolysis to remove peptides from its N-terminal region, these peptides may be produced in articular cartilage during the normal process of turnover and ageing. Although a physiological function for this protein has not been established, it may have a homeostatic role in the regulation of proteoglycan synthesis.

Abstract
Components of kallikrein-kininogen-kinin are activated in response to noxious stimuli (chemical, physical or bacterial), which may lead to excessive release of kinins in the synovial joints that may produce inflammatory joint disease. The inflammatory changes observed in synovial tissue may be due to activation of B2 receptors. Kinins also stimulate the synthesis of other pro-inflammatory agents (PGs, LTs, histamine, EDRF, PGI2 and PAF) in the inflamed joint. B2 receptor antagonists may provide valuable new analgesic drugs. The mode of excessive kinin release in inflamed synovial joints leads to stimulation of pro-inflammatory actions of B2 kinin receptors. These properties could be antagonized by novel B2 receptor antagonists (see Fig. 4). Further, it is suggested that substances directed to reduce the activation of KKS may provide a pharmacological basis for the synthesis of novel antirheumatic or anti-inflammatory drugs.
