    Helicobacter pylori (H. pylori) infection and non-steroidal anti-inflammatory drugs (NSAIDs) or aspirin induce serious gastrointestinal ulcer and bleeding. Also both H. pylori infection and NSAIDs or aspirin use independently and significantly increase the risk of peptic ulcer and its complications. Interestingly, it has been reported that no evidence exists that reducing the dose or using modified release formulations such as enteric-coated of aspirin would reduce the incidence of ulcer bleeding. Selective COX-2 inhibitors use shows a low relative risk of ulcer bleeding than NSAIDs. However, when combined with aspirin, the differences between selective COX-2 inhibitors and NSAIDs tend to disappear. NSAIDs/aspirin dominantly develops multiple ulcers from the angulus to the antrum regardless of H. pylori infection. In contrast, the irregular shape of ulcer is more frequently detected in patients taking NSAIDs in comparison with H. pylori-associated ulcer, but the association was not seen in cases taking aspirin. This result indicates that the mechanism of ulcer formation may be different between NSAIDs and aspirin.

    To investigate the efficacy and safety of rabeprazole under continuous non-steroidal anti-inflammatory drug (NSAID) administration for NSAID-induced ulcer in Japan. Subjects comprised patients undergoing NSAID treatment in whom upper gastrointestinal endoscopy revealed an ulcerous lesion (open ulcer) with diameter > or = 3 mm, who required continuous NSAID treatment. Endoscopies were performed at the start of treatment, during the treatment period, and at the conclusion (or discontinuation) of treatment. Findings were evaluated as size (maximum diameter) and stage based on the Sakita-Miwa classification. An ulcer was regarded as cured when the "white coating" was seen to have disappeared under endoscopy. As criteria for evaluating safety, all medically untoward symptoms and signs (adverse events, laboratory abnormalities, accidental symptoms, etc.) occurring after the start of rabeprazole treatment were handled as adverse events. Endoscopic cure rate in 38 patients in the efficacy analysis (endoscopic evaluation) was 71.1% (27/38). Among those 38 patients, 35 had gastric ulcer with a cure rate of 71.4% (25/35), and 3 had duodenal ulcer with a cure rate of 66.7% (2/3). Three adverse drug reactions were reported from 64 patients in the safety analysis (interstitial pneumonia, low white blood cell count and pruritus); thus, the incidence rate for adverse drug reactions was 4.7% (3/64). The treatment efficacy of rabeprazole for NSAID-induced ulcer under continuous NSAID administration was confirmed.

    Non-steroidal anti-inflammatory drugs (NSAIDs) are a broad class of non glucocorticoid drugs which are extensively used in anti-inflammatory, analgesic, and antipyretic therapies. However, NSAIDs may cause many side effects, most commonly in gastrointestinal(GI) tract. Cardiovascular system, kidney, liver, central nervous system and hematopoietic system are also involved. NSAID-induced GI side effects not only endanger the patients' health, increase mortality, but also greatly increase the cost of medical care. Therefore, how to reduce GI side effects is of particular concern to clinicians. The Chinese Rheumatism Data Center(CRDC) and Chinese Systemic Lupus Erythematosus Treatment and Research Group(CSTAR) compose a "Recommendation for the prevention and treatment of non-steroidal anti-inflammatory drug-induced gastrointestinal ulcers and its complications" , as following: (1) GI lesions are the most common side effects of NSAIDs. (2) NSAID-induced GI side effects include gastritis, esophagitis, gastric and duodenal ulcers, bleeding, perforation and obstruction. (3) With the application of capsule endoscopy and small intestinal endoscopy, growing attention is being paid to the NASID-induced small intestine mucosa damage, which is mainly erosion and ulcer. (4) Risk factors related to NSAID-induced GI ulcers include: Helicobacter pylori (Hp) infection, age> 65 years, past history of GI ulcers, high doses of NSAIDs, multiple-drug combination therapy, and comorbidities, such as cardiovascular disease and nephropathy.(5) GI and cardiovascular function should be evaluated before using NSAIDs and gastric mucosal protective agents. (6) The risk of GI ulcers and complications caused by selective cyclooxygenase-2 (COX-2) inhibitors is less than that of non-selective COX-2 inhibitors. (7)Hp eradication therapy helps to cure GI ulcers and prevent recurrence when Hp infection is positive in NSAID-induced ulcers. (8) Proton pump inhibitor (PPI) is the first choice for the

    Proton-pump inhibitors such as omeprazole are a standard treatment to prevent non-steroidal anti-inflammatory drug-induced upper gastrointestinal mucosal injuries. However, it is unclear which drugs may protect against all NSAID-induced digestive-tract injuries. Here, we compare the efficacy of the gastromucoprotective drug irsogladine with omeprazole in preventing NSAID-induced esophagitis, peptic ulcers, and small-intestinal mucosal injury in healthy subjects. Thirty-two healthy volunteers were assigned to an irsogladine group (Group I; n = 16) receiving diclofenac sodium 75 mg and irsogladine 4 mg daily for 14 days, or an omeprazole group (Group O; n = 16) receiving diclofenac sodium 75 mg and omeprazole 10 mg daily for 14 days. Esophagitis and peptic ulcers were evaluated by esophagogastroduodenoscopy and small-intestinal injuries by capsule endoscopy, fecal calprotectin, and fecal occult blood before and after treatment. There was no significant difference between Group I and Group O with respect to the change in lesion score in the esophagus, stomach, and duodenum before and after treatment.NSAID treatment significantly increased the number of small intestinal mucosal breaks per subject by capsule endoscopic evaluation, from a basal level of 0.1 ± 0.3 up to 1.9 ± 2.0 lesions in Group O (p = 0.0002). In contrast, there were no significant changes in the mean number of mucosal breaks before and after co-treatment in Group I (0.3 ± 0.8 to 0.5 ± 0.7, p = 0.62), and the between-group difference was significant (p = 0.0040). Fecal calprotectin concentration, when the concentration before treatment was defined as 1, was significantly increased both in Group O (from 1.0 ± 0.0 to 18.1 ± 37.1, p = 0.0002) and Group I (from 1.0 ± 0.0 to 6.0 ± 11.1, p = 0.0280); the degree of increase in Group O was significantly higher compared with that in Group I (p<0.05). In addition, fecal occult blood levels increased significantly in Group O (p = 0.0018), but there

    Evaluating small bowel patency is recommended for capsule endoscopy in patients suspected of nonsteroidal anti-inflammatory drug-induced (NSAID) enteropathy. The aim of this investigation was to examine whether radiography is a candidate of patency tool in NSAID enteropathy. We reviewed double-contrast barium enteroclysis in 21 patients with NSAID enteropathy diagnosed either by capsule endoscopy or balloon-assisted endoscopy. The endoscopic findings were classified into circular ulcers, linear ulcers and small mucosal defects. The radiographic signs of the corresponding endoscopic findings were retrieved and the depiction rate was calculated. Of the 21 patients, endoscopy detected circular ulcers, linear ulcers, and small ulcers in 12, 3 and 12 patients, respectively. Small bowel radiography depicted circular narrowing as pseudo-folds in 10 patients (83%) and linear ulcers as eccentric rigidity in 2 patients (67%). However, radiography was able to depict small mucosal defects in only 3 patients (17%). Two of 5 patients with pseudo-folds experienced retention of the capsule. "Pseudo-folds" is a sign corresponding to circular ulcer in NSAID enteropathy, which may be predictive of capsule retention.

  7. Management of Nonsteroidal Anti-Inflammatory Drug-Induced Gastroduodenal Disease by Acid Suppression

    Full Text Available One major cause of peptic ulceration is the use of nonsteroidal anti-inflammatory drugs (NSAIDs. The precise mechanisms through which NSAIDs cause peptic ulceration are unknown, but the discovery that they reduce the production of ‘cytoprotective’ prostaglandins led to the hypothesis that coadministration of exogenous prostaglandins heals and prevents NSAID-induced gastroduodenal ulcers and other mucosal lesions. Studies using high doses of misoprostol have shown that it does have a protective effect; however, gastrointestinal intolerance of this prostaglandin E2 analogue is common. Early indications that acid suppression was effective in the management of NSAID-related peptic ulcers came from studies showing that gastric ulcers could be healed by omeprazole in patients who continued to take NSAIDs. Other studies suggested that acid suppression reduces the incidence of mucosal lesions but that standard dose ranitidine protects only against duodenal lesions. Subsequent studies reported that higher dose H2 receptor antagonist therapy can protect against both gastric and duodenal ulcers during continued NSAID therapy. An ideal therapeutic strategy would heal NSAID-related ulcers and prevent the development of new NSAID-related lesions and complications in patients who are unable to discontinue NSAID therapy. A number of recent studies indicate that effective acid-suppressive treatment with the proton pump inhibitor omeprazole can achieve these aims. Overall, data from recent studies show that acid suppression with the proton pump inhibitor omeprazole at a dose of 20 mg daily is the most effective means of healing NSAID-associated gastroduodenal lesions and that it is the most effective prophylactic therapy. In the long run, the role of omeprazole will have to be evaluated with respect to its cost effectiveness compared with other strategies and with respect to the development of less damaging NSAIDs.

  8. Effect of lipid molecule headgroup mismatch on non steroidal anti-inflammatory drugs induced membrane fusion.

    Membrane fusion is an essential process guiding many important biological events, which most commonly requires the aid of proteins and peptides as fusogenic agents. Small drug induced fusion at low drug concentration is a rare event. Only three drugs, namely, meloxicam (Mx), piroxicam (Px), and tenoxicam (Tx), belonging to the oxicam group of non steroidal anti-inflammatory drugs (NSAIDs) have been shown by us to induce membrane fusion successfully at low drug concentration. A better elucidation of the mechanism and the effect of different parameters in modulating the fusion process will allow the use of these common drugs to induce and control membrane fusion in various biochemical processes. In this study, we monitor the effect of lipid headgroup size mismatch in the bilayer on oxicam NSAIDs induced membrane fusion, by introducing dimyristoylphosphatidylethanolamine (DMPE) in dimyristoylphosphatidylcholine (DMPC) small unilamellar vesicles (SUVs). Such headgroup mismatch affects various lipid parameters which includes inhibition of trans-bilayer motion, domain formation, decrease in curvature, etc. Changes in various lipidic parameters introduce defects in the membrane bilayer and thereby modulate membrane fusion. SUVs formed by DMPC with increasing DMPE content (10, 20, and 30 mol %) were used as simple model membranes. Transmission electron microscopy (TEM) and differential scanning calorimetry (DSC) were used to characterize the DMPC-DMPE mixed vesicles. Fluorescence assays were used to probe the time dependence of lipid mixing, content mixing, and leakage and also used to determine the partitioning of the drugs in the membrane bilayer. How the inhibition of trans-bilayer motion, heterogeneous distribution of lipids, decrease in vesicle curvature, etc., arising due to headgroup mismatch affect the fusion process has been isolated and identified here. Mx amplifies these effects maximally followed by Px and Tx. This has been correlated to the enhanced

  10. Anti-inflammatory effects of nicotine in obesity and ulcerative colitis

    Full Text Available Abstract Cigarette smoke is a major risk factor for a number of diseases including lung cancer and respiratory infections. Paradoxically, it also contains nicotine, an anti-inflammatory alkaloid. There is increasing evidence that smokers have a lower incidence of some inflammatory diseases, including ulcerative colitis, and the protective effect involves the activation of a cholinergic anti-inflammatory pathway that requires the α7 nicotinic acetylcholine receptor (α7nAChR on immune cells. Obesity is characterized by chronic low-grade inflammation, which contributes to insulin resistance. Nicotine significantly improves glucose homeostasis and insulin sensitivity in genetically obese and diet-induced obese mice, which is associated with suppressed adipose tissue inflammation. Inflammation that results in disruption of the epithelial barrier is a hallmark of inflammatory bowel disease, and nicotine is protective in ulcerative colitis. This article summarizes current evidence for the anti-inflammatory effects of nicotine in obesity and ulcerative colitis. Selective agonists for the α7nAChR could represent a promising pharmacological strategy for the treatment of inflammation in obesity and ulcerative colitis. Nevertheless, we should keep in mind that the anti-inflammatory effects of nicotine could be mediated via the expression of several nAChRs on a particular target cell.

    Full Text Available Non-steroidal anti-inflammatory drug (NSAIDs induced enteropathy represents an important complication of one of the most commonly used drugs worldwide. Due to previous diagnostics difficulties the real prevalence of this disease was underestimated for a long time. The pathogenesis of NSAID-enteropathy is more multifactorial and complex than formerly assumed but has still not been fully uncovered. A combination of the local and systemic effect plays an important role in pathogenesis. Thanks to novel enteroscopy methods (wireless capsule endoscopy, double balloon enteroscopy, small bowel lesions are described in a substantial section of NSAID users although most are clinically asymptomatic. The other non-invasive tests (small bowel permeability, faecal calprotectin, scintigraphy using faecal excretion of 111-indium-labelled leukocytes etc. proposed for diagnostics are not generally used in clinical practice, mainly because of their non-specificity. Despite intensive research into possible treatment, the main measure for patients with NSAID-enteropathy is still withdrawal of NSAIDs. Double balloon enteroscopy plays an important role in the treatment of complications (bleeding, strictures.

    Nonsteroidal anti-inflammatory drugs (NSAIDs) often cause ulcers in the small intestine in humans, but there are few effective agents for treatment of small intestinal ulcers. We found that soluble dietary fibers (SDFs), such as pectin, could prevent the formation of small intestinal lesions induced by indomethacin (IND) in cats. To elucidate the mechanism of protection by SDFs, we examined the viscosities of SDFs and the effects of pectin on gastrointestinal absorption of IND and intestinal hypermotility induced by IND. Cats were given regular dry food (RFD-Dry) or RFD-Dry supplemented with pectin, guar gum, polydextrose, or mucin twice daily. IND was administered orally once daily for 3 days. Mucosal lesions in the small intestine were examined 24 h after the final dosing of IND. Plasma concentrations of IND were measured by HPLC. GI motilities were measured using a telemetry system in conscious cats implanted with force transducers. Viscosities of the SDFs were measured using a viscosimeter. In cats given RFD-Dry, IND (3 mg/kg) increased motility and produced many lesions in the lower half of the small intestine; the total lesion area (TLA) was 7.5 +/- 2.6 cm(2) (n = 4). Lesions induced by IND were markedly decreased in cats given RFD-Dry supplemented with 3% pectin, guar gum, polydextrose or mucin; TLAs were 0.6 +/- 0.3, 0.0 +/- 0.0, 1.3 +/- 0.8 and 1.6 +/- 0.5 cm(2) (n = 4) (P 1,200, 1 and 4, respectively. Pectin did not affect the absorption of IND nor did it inhibit IND-induced intestinal hypermotility. SDFs protect the small intestine against NSAID-induced damage, probably by compensating a barrier function of the mucin decreased by IND. Viscosities of the SDFs play a role, at least in part, in the protective effects of the SDFs on the small intestine.

    Helicobacter pylori is now recognized as a frequent cause of histological chronic gastritis, and this has radically changed our understanding of this common condition. In the light of these developments, the traditional view that non-steroidal anti-inflammatory drugs are one of the common 'environmental' causes of chronic gastritis has been re-examined. Gastric mucosal biopsies have been studied from 430 patients undergoing routine upper gastrointestinal endoscopy, 99 of whom had recently been taking non-steroidal anti-inflammatory drugs. No significant association was found between the use of these drugs and either the presence of chronic gastritis or the frequency of colonization with H. pylori, although there was a strong association (P less than 0.0001) between H. pylori and gastritis. Non-steroidal anti-inflammatory drugs appear, however, to modify the inflammatory process in the gastric body, leading to a lower frequency of atrophic gastritis (P less than 0.05). The majority of peptic ulcers were associated with H. pylori irrespective of non-steroidal anti-inflammatory drug use, but there was a higher frequency of H. pylori negative ulceration in the patients who had used these agents (P less than 0.04). Peptic ulceration was uncommon in the absence of either H. pylori or recent non-steroidal anti-inflammatory drug use.

    Selective serotonin reuptake inhibitors (SSRIs) have been reported to have an increased risk of gastrointestinal adverse events, and the risk may be further increased by combined use of nonsteroidal anti-inflammatory drugs (NSAIDs). However, little has been known about the risk of peptic ulcer associated with other classes of antidepressants or individual antidepressants combined with NSAIDs. We conducted a retrospective cohort study to define the risk of peptic ulcer associated with combined use of antidepressants and NSAIDs, as compared with use of antidepressants alone. Using the Korean Health Insurance Review and Assessment Service database, we identified a total of 1,127,622 patients who began receiving antidepressants between 2009 and 2012. Propensity-based matching and Cox proportional hazards models were used to compare the risk of peptic ulcer between antidepressant users with NSAIDs and those without NSAIDs matched in a 1:1 ratio, for a total of 768,850 patients. The risk of peptic ulcer did not increase with combined use of overall antidepressants and NSAIDs, as compared with antidepressant use alone (hazard ratio [HR], 1.02; 95% confidence interval [CI], 0.99-1.06). A slightly increased risk was observed for combined use of NSAIDs with tricyclic antidepressants (HR, 1.15; 95% CI, 1.09-1.21) and with SSRIs (HR, 1.08; 95% CI, 1.01-1.16). We found that although concomitant use of NSAIDs and antidepressants was not associated with an increased risk of peptic ulcer for antidepressants in general, it was so for some specific classes including tricyclic antidepressants and SSRIs. However, we cannot rule out the possibility that the increased risk was solely due to NSAID use.

    Ursolic acid (UA) has been reported to have a protective effect in colitis. However, the underlying mechanisms remain to be elucidated. In the present study, experimental ulcerative colitis was induced in male BALB/c mice by the administration of 5% dextran sulfate sodium (DSS) for 7 days, followed by treatment with UA for another 7 days. Hematoxylin & eosin staining was performed to evaluate colon tissue damage, and enzyme assays were used to measure malondialdehyde (MDA) content and superoxide dismutase (SOD) activity in colon homogenate. In addition, serum levels of interleukin (IL)‑1β and tumor necrosis factor (TNF)‑α were measured using an ELISA, and the level of nuclear factor (NF)‑κB p65 in the colonic tissues was assessed by western blotting. The 7‑day DSS administration induced marked colon damage, increased the serum levels of IL‑1β and TNF‑α, increased MDA content and decreased SOD activity in the colon homogenate. These changes were significantly improved by treatment with UA. UA also reduced the DSS‑stimulated high nuclear level of NF‑κB p65 in the colon tissues. These results demonstrate a protective role of UA in ulcerative colitis, and suggest that anti-inflammatory and antioxidant activities are involved in the underlying mechanisms.

    Directory of Open Access Journals (Sweden)

    2004-01-01

    Full Text Available Nonsteroidal anti-inflammatory drugs (NSAIDs cause damage in the upper gastrointestinal (GI tract by impairing the ability of the mucosa to resist and respond to injury. Many of these effects of NSAIDs can be attributed to their ability to suppress mucosal prostaglandin synthesis. Selective inhibitors of cyclooxygenase (COX-2 are less likely to disrupt mucosal defence and do not interfere with platelet aggregation. Thus, their use is associated with a reduced incidence of serious GI adverse events; however, a significant risk of such events still persists. At least in animal models, selective COX-2 inhibitors interfere with ulcer healing to the same extent as conventional NSAIDs. In contrast, COX-inhibiting nitric oxide donors (CINODs produce anti-inflammatory and analgesic effects comparable or superior to those of NSAIDs, but with greatly reduced GI toxicity. Unlike NSAIDs and selective COX-2 inhibitors, CINODs do not interfere with ulcer healing. Moreover, because CINODs suppress the activity of both COX-1 and COX-2, they do not share with selective COX-2 inhibitors the lack of cardioprotection afforded by significant suppression of platelet aggregation. Because of their safety profile, CINODs may be particularly useful for long term prevention applications, such as for colon cancer, cardiovascular disease and Alzheimer's disease.

    To date, genetic studies of hypersensitivity reactions to non-steroidal anti-inflammatory drugs (NSAIDs) have been carried out mainly in aspirin-induced asthma and to a lesser extent in chronic urticaria, with no studies in patients with acute urticaria (AU), the most common entity induced by these drugs. In this work, we analysed the association of common variants of 15 relevant genes encoding both enzymes and receptors from the arachidonic acid (AA) pathway with NSAID-induced AU. Patients were recruited in several Allergy Services that are integrated into the Spanish network RIRAAF, and diagnosed of AU induced by cross-intolerance (CRI) to NSAIDs. Genotyping was carried out by TaqMan allelic discrimination assays. A total of 486 patients with AU induced by CRI to NSAIDs and 536 unrelated controls were included in this large Spanish case-control study. Seven variants from 31 tested in six genes were associated in a discovery study population from Malaga (0.0003 ≤ p-value ≤ 0.041). A follow-up analysis in an independent sample from Madrid replicated three of the SNPs from the ALOX15 (rs7220870), PTGDR (rs8004654) and CYSLTR1 (rs320095) genes (1.055x10(-6) ≤meta-analysis p-value ≤ 0.003). Genetic variants of the AA pathway may play an important role in NSAID-induced AU. These data may help understand the mechanism underlying this disease. © 2012 Blackwell Publishing Ltd.

    Full Text Available Capsule endoscopy and balloon endoscopy, advanced modalities that allow full investigation of the entire small intestine, have revealed that nonsteroidal anti-inflammatory drugs (NSAIDs can cause a variety of abnormalities in the small intestine. Recently, several reports show that traditional NSAIDs (tNSAIDs and acetylsalicylic acid (ASA can induce small intestinal injuries. These reports have shown that the preventive effect of proton pump inhibitors (PPIs does not extend to the small intestine, suggesting that concomitant therapy may be required to prevent small intestinal side effects associated with tNSAID/ASA use. Recently, several randomized controlled trials used capsule endoscopy to evaluate the preventive effect of mucoprotective drugs against tNSAID/ASA-induced small intestinal injury. These studies show that misoprostol and rebamipide reduce the number and types of tNSAID-induced small intestinal mucosal injuries. However, those studies were limited to a small number of subjects and tested short-term tNSAID/ ASA treatment. Therefore, further extensive studies are clearly required to ascertain the beneficial effect of these drugs.

    INTRODUCTION: Helicobacter pylori (HP) infection and use of nonsteroidal anti-inflammatory drugs (NSAIDs)/acetyl salicylic acid (ASA) are risk factors for bleeding peptic ulcer. HP eradication reduces the risk of rebleeding. Antibiotics, proton pump inhibitors (PPI) and presence of blood...... years. The HP-prevalence was 34%, and 81% had used NSAID/ASA, as compared with 55% in 1990-1992. The proportion of idiopathic peptic ulcer disease was 6.6%. At admission, 19% and 17% of the patients were in treatment with PPI and antibiotics, respectively. Thirteen percent of the initially HP...... in the stomach can affect the HP test. The objectives of this study were to determine the HP prevalence and NSAID/ASA use in patients with bleeding ulcer in a low-prevalence HP area, to determine the proportion of idiopathic ulcers and to estimate the proportion of initially false negative HP tests.

    This article reports the assessment of anti-inflammatory, antiulcer and neuropharmacological activities of crude extract of Cyperus rotundus. The plant exhibited significant property to act as an anti inflammatory agent. In experimental design, inflammation was produced by carrageenan in rats and compare with saline treated and Aspirin treated group. Simultaneously the drug was also observed for its antiulcer response and found effective enough (these two activities were observed at the dosage of 300mg/kg and 500mg/kg). The anti ulcer activity was observed 41.2% as a dosage of 500mg/kg. Neuropharmacological activities (open field, head dip, rearing traction and forced swimming test) were also observed at 300 and 500mg/kg of C. rotundus extract. The crude extract showed mild decreased in all test and exhibited slight muscle relaxant effect. Powder drug studies and FTIR analysis were performed for the authentication of C. rotundus.

    A critical component of drug addiction research involves identifying novel biological mechanisms and environmental predictors of risk or resilience to drug addiction and associated relapse. Increasing evidence suggests microglia and astrocytes can profoundly affect the physiological and addictive properties of drugs of abuse, including morphine. We report that glia within the rat nucleus accumbens (NAcc) respond to morphine with an increase in cytokine/chemokine expression, which predicts future reinstatement of morphine conditioned place preference (CPP) following a priming dose of morphine. This glial response to morphine is influenced by early-life experience. A neonatal handling paradigm that increases the quantity and quality of maternal care significantly increases baseline expression of the anti-inflammatory cytokine IL-10 within the NAcc, attenuates morphine-induced glial activation, and prevents the subsequent reinstatement of morphine CPP in adulthood. IL-10 expression within the NAcc and reinstatement of CPP are negatively correlated, suggesting a protective role for this specific cytokine against morphine-induced glial reactivity and drug-induced reinstatement of morphine CPP. Neonatal handling programs the expression of IL-10 within the NAcc early in development, and this is maintained into adulthood via decreased methylation of the IL-10 gene specifically within microglia. The effect of neonatal handling is mimicked by pharmacological modulation of glia in adulthood with ibudilast, which increases IL-10 expression, inhibits morphine-induced glial activation within the NAcc, and prevents reinstatement of morphine CPP. Taken together, we have identified a novel gene × early-life environment interaction on morphine-induced glial activation and a specific role for glial activation in drug-induced reinstatement of drug-seeking behavior.

    The use of proton pump inhibitors for prevention of nonsteroidal anti-inflammatory drug (NSAID)-induced gastrointestinal adverse events is well documented. However, data regarding the efficacy and safety of this approach in Japan are scarce. To evaluate the efficacy and tolerability of esomeprazole in preventing NSAID-induced peptic ulcers in Japanese at-risk patients. Male and female Japanese adult patients (aged ≥ 20 years) with endoscopically confirmed history of peptic ulcers who required long-term oral NSAID therapy for a chronic inflammatory condition were randomised to 24 weeks' treatment with esomeprazole 20 mg once daily or matching placebo. The primary end point was the Kaplan-Meier estimated proportion of ulcer-free patients. Overall, 343 patients were randomised to treatment (esomeprazole, n = 175; placebo, n = 168). The Kaplan-Meier estimated ulcer-free rate over the 24-week treatment period was significantly higher (log-rank P < 0.001) in esomeprazole-treated patients (96.0%; 95% CI 92.8, 99.1) than in placebo recipients (64.4%; 95% CI 56.8, 71.9). Esomeprazole was effective at preventing peptic ulcers in both Helicobacter pylori-positive and -negative patients (96.3% vs. 95.5% of patients ulcer-free, respectively); however, in the placebo group, the proportion of ulcer-free patients at 24 weeks was markedly lower among H. pylori-positive than -negative patients (59.7% vs. 69.9%). The NSAID type did not seem to affect the estimated ulcer-free rate with esomeprazole. Treatment with esomeprazole was well tolerated. Esomeprazole 20 mg once daily is effective and safe in preventing ulcer recurrence in Japanese patients with a definite history of peptic ulcers who were taking an NSAID (ClinicalTrials.gov identifier: NCT00542789). © 2012 Blackwell Publishing Ltd.

  9. Role of dietary fiber in formation and prevention of small intestinal ulcers induced by nonsteroidal anti-inflammatory drug.

    Recent advances in endoscopic techniques such as capsule endoscopy have revealed that nonsteroidal anti-inflammatory drugs (NSAIDs) often cause ulcers in the small intestine in humans, but there are few effective agents for treatment of small intestinal ulcers. Although the pathogenesis of NSAID-induced intestinal ulcer has been widely studied, dietary factors have seldom been considered. In the present review, the role of dietary fiber (DF) in the formation of NSAID-induced intestinal ulcers is discussed. In previous studies, small intestinal lesions were not observed when NSAIDs were administered to fasted rats, dogs, and cats, but were observed in conventionally-fed animals, suggesting the importance of feeding in the formation of intestinal lesions induced by NSAIDs. However, in animals fed diets containing low or no DF, indomethacin (IND) did not produce lesions in the small intestine, but did produce lesions in animals fed diets supplemented with insoluble dietary fiber (IDF, cellulose). The results suggest that IDF in the diet plays an important role in the formation of NSAID-induced intestinal lesions. On the other hand, addition of soluble dietary fibers (SDFs) such as pectin or mucin to regular diet markedly decreased NSAID-induced intestinal lesions. Thus, IDF and SDF have opposing effects on IND-induced intestinal lesions, i.e., IDF is harmful while SDF is protective. SDFs potentially represent a novel and safe means for protecting the small intestine against NSAID-induced intestinal lesions.

    Angiogenesis, the formation of new capillary blood vessels, is essential not only for the growth and metastasis of solid tumors, but also for wound and ulcer healing, because without the restoration of blood flow, oxygen and nutrients cannot be delivered to the healing site. Nonsteroidal anti-inflammatory drugs (NSAIDs) such as aspirin, indomethacin and ibuprofen are the most widely used drugs for pain, arthritis, cardiovascular diseases and, more recently, the prevention of colon cancer and Alzheimer disease. However, NSAIDs produce gastroduodenal ulcers in about 25% of users (often with bleeding and/or perforations) and delay ulcer healing, presumably by blocking prostaglandin synthesis from cyclooxygenase (COX)-1 and COX-2 (ref. 10). The hypothesis that the gastrointestinal side effects of NSAIDs result from inhibition of COX-1, but not COX-2 (ref. 11), prompted the development of NSAIDs that selectively inhibit only COX-2 (such as celecoxib and rofecoxib). Our study demonstrates that both selective and nonselective NSAIDs inhibit angiogenesis through direct effects on endothelial cells. We also show that this action involves inhibition of mitogen-activated protein (MAP) kinase (ERK2) activity, interference with ERK nuclear translocation, is independent of protein kinase C and has prostaglandin-dependent and prostaglandin-independent components. Finally, we show that both COX-1 and COX-2 are important for the regulation of angiogenesis. These findings challenge the premise that selective COX-2 inhibitors will not affect the gastrointestinal tract and ulcer/wound healing.

    Non-Helicobacter pylori, non-NSAID peptic ulcer disease (PUD), termed idiopathic PUD, is increasing in Korea. Diagnosis is based on exclusion of common causes such as H. pylori infection, infection with other pathogens, surreptitious ulcerogenic drugs, malignancy, and uncommon systemic diseases with upper gastrointestinal manifestations. The clinical course of idiopathic PUD is delayed ulcer healing, higher recurrence, higher re-bleeding after initial ulcer healing, and higher mortality than the other types of PUD. Genetic predisposition, older age, chronic mesenteric ischemia, cigarette smoking, concomitant systemic diseases, and psychological stress are considered risk factors for idiopathic PUD. Diagnosis of idiopathic PUD should systematically explore all possible causes. Management of this disease is to treat underlying disease followed by regular endoscopic surveillance to confirm ulcer healing. Continuous proton pump inhibitor therapy is an option for patients who respond poorly to the standard ulcer regimen.

    The clinical epidemiological studies included in this thesis fall into three parts. The first part includes studies on birth outcome in women with ulcerative colitis. The second part includes pharmacoepidemiological studies on birth outcome after anti-inflammatory drug therapy in pregnancy, including patients with ulcerative colitis and Crohn's disease. The third part (and the latest publications) includes birth outcome in women with Crohn's disease; and the methods of cohort establishment in these studies are developed and improved due to the knowledge gathered from conducting the earlier studies. The birth outcomes in women with ulcerative colitis are examined in a nationwide, Danish, cohort of women based on data from the Danish National Hospital Discharge Registry and the Danish Medical Birth Registry, and within a Hungarian case-control data set. Our data suggest: 1) Significantly increased risk of preterm birth when women give birth 0-6 months after establishment of the diagnosis. It is considered whether the increased risk may be influenced by disease activity around the time of establishing the diagnosis. 2) No increased risk of giving birth to children with low birth weight, intrauterine growth retardation or congenital abnormalities (evaluated overall). 3) Significantly increased risk of some selected congenital abnormalities (limb deficiencies, obstructive urinary and multiple congenital abnormalities). No other studies have examined the risk of selected congenital abnormalities in children born by women with ulcerative colitis. The pharmacoepidemiological studies on birth outcomes after use of anti-inflammatory drug therapy in pregnancy, including women with ulcerative colitis and Crohn's disease, are based on data from the Hungarian case-control data set, a countywide Danish prescription Database, the Danish National Hospital Discharge Registry, the Danish Medical Birth Registry, and review of selected medical records.

    Despite decreasing Helicobacter pylori prevalence, the prevalence of peptic ulcer disease is increasing in the aged population, mainly due to increasing use of NSAIDs to manage pain and inflammation. In addition, low dose aspirin is employed as an anti-coagulant for those who have suffered or are at high risk of ischemic stroke and cardiovascular disease. However, NSAIDs and aspirin are injurious to mucosa of stomach and duodenum. NSAID-induced inhibition of mucosal prostaglandin synthesis is thought to be a major mechanism of gastrointestinal mucosal injury. The proportion of elderly has increased rapidly in Korea, with the proportion over 65 years old expected to be 24.3% in 2030. In this higher-risk population, the strategy to reduce the incidence of NSAID-related peptic ulcers and complications such as bleeding, obstruction and perforation is very important. Proton pump inhibitors (PPIs) with cyclooxygenase-2 inhibitor can be used for reducing the risk of NSAID-related ulcers and upper gastrointestinal (GI) complications. However, continuous use of PPI has several problems. In addition, NSAID-related problems in the lower GI tract have increased, in contrast to the decrease of NSAID-related upper GI disease. The aim of this review is to provide an evidence-based knowledge regarding the mechanism, complications of treatment, and prevention strategies for NSAID- or aspirin-related peptic ulcer disease in Korea.

    Full Text Available Gastric ulcers are among the most common diseases affecting humans. This study aimed at investigating the gastroprotective effects of manuka honey against ethanol-induced gastric ulcers in rats. The mechanism by which honey exerts its antiulcer potential was elucidated. Four groups of rats were used: control, ethanol (ulcer, omeprazole, and manuka honey. Stomachs were examined macroscopically for hemorrhagic lesions in the glandular mucosa, histopathological changes, and glycoprotein detection. The effects of oxidative stress were investigated using the following indicators: gastric mucosal nitric oxide (NO, reduced glutathione (GSH, lipid peroxide (MDA, measured as malondialdehyde glutathione peroxidase (GPx, superoxide dismutase (SOD, and catalase. Plasma tumour necrosis factor-α, interleukin-1β, and IL-6 were also measured. Manuka honey significantly decreased the ulcer index, completely protected the mucosa from lesions, and preserved gastric mucosal glycoprotein. It significantly increased gastric mucosal levels of NO, GSH, GPx, and SOD. Manuka honey also decreased gastric mucosal MDA and plasma TNF-α, IL-1β, and IL-6 concentrations. In conclusion, manuka honey likely exerted its antiulcer, effect by keeping enzymatic (GPx and SOD and nonenzymatic (GSH and NO antioxidants as well as inflammatory cytokines (TNF-α, IL-1β, and IL-6 in a reduced form, inhibited lipid peroxidation (MDA, and preserved mucous glycoproteins levels.

    Gastric ulcers are a major problem worldwide with no effective treatment. The objective of this study was to evaluate the use of manuka honey in the treatment of acetic acid-induced chronic gastric ulcers in rats. Different groups of rats were treated with three different concentrations of honey. Stomachs were checked macroscopically for ulcerative lesions in the glandular mucosa and microscopically for histopathological alterations. Treatment with manuka honey significantly reduced the ulcer index and maintained the glycoprotein content. It also reduced the mucosal myeloperoxidase activity, lipid peroxidation (MDA), and the inflammatory cytokines (TNF-α, IL-1β, and IL-6) as compared to untreated control group. In addition, honey-treated groups showed significant increase in enzymatic (GPx and SOD) and nonenzymatic (GSH) antioxidants besides levels of the anti-inflammatory cytokine IL-10. Flow cytometry studies showed that treatment of animals with manuka honey has normalized cell cycle distribution and significantly lowered apoptosis in gastric mucosa. In conclusion, the results indicated that manuka honey is effective in the treatment of chronic ulcer and preservation of mucosal glycoproteins. Its effects are due to its antioxidant and anti-inflammatory properties that resulted in a significant reduction of the gastric mucosal MDA, TNF-α, IL-1β, and IL-6 and caused an elevation in IL-10 levels.

    Non-steroidal anti-inflammatory drugs (NSAIDs) have been implemented in clinical settings for a long time for their anti-inflammatory effects. With the number of NSAID users increasing, gastroenterological physicians and researchers have worked hard to prevent and treat NSAID-induced gastric mucosal injury, an effort that has for the large part being successful. However, the struggle against NSAID-induced mucosal damage has taken on a new urgency due to the discovery of NSAID-induced small intestinal mucosal injury. Although the main mechanism by which NSAIDs induce small intestinal mucosal injury has been thought to depend on the inhibitory effect of NSAIDs on cyclooxygenase (COX) activity, recent studies have revealed the importance of mitochondria-derived reactive oxygen species (ROS) production, which occurs independently of COX-inhibition. ROS production is an especially important factor in the increase of small intestinal epithelial cell permeability, an early stage in the process of small intestinal mucosal injury. By clarifying the precise mechanism, together with its clinical features using novel endoscopy, effective strategies for preventing NSAID-induced small intestinal damage, especially targeting mitochondria-derived ROS production, may be developed.

    Full Text Available Chronic gastritis and gastric ulcers are prevalent throughout the world and are considered to be a global health problem. Modified Xiaochaihutang (MXCHT prescription is broadly used in traditional medicine hospital for the treatment of gastritis. In order to assess the anti-Helicobacter pylori (H. pylori effect of MXCHT, agar diffusion method in vitro and fluid dilution method for the minimal inhibitory concentration (MIC were established. The anti-inflammatory effects were then evaluated using mouse ear edema model and rat paw edema model. The ethanol-induced gastric ulcer method was employed to verify the gastroprotective effect of active extracts in MXCHT. HPLC-TOF-MS/MS was used for analyzing the possible active constituents after oral administration of effective extracts in ethanol-induced gastric ulcer models. MXCHT and 4 different extracts of the bacterial inhibition diameter and MIC were dramatically decreased compared with control group, showing anti-Helicobacter pylori effects. High dose groups of MXCHT, water extract, EtOAc extract, and n-BuOH extract displayed significant anti-inflammatory effects in xylene-induced mouse ear edema model and carrageenan-induced rat paw edema model test. MXCHT and all active extracts exhibited gastroprotective activity and prevented gastric lesions induced by ethanol in rats. 4 prototype components and 4 metabolites were identified after oral administration of EtOAc extract. In addition, 6 prototype components and 6 metabolites were identified in n-BuOH extract. MXCHT, EtOAc extract, and n-BuOH extract demonstrate gastroprotective effects through anti-Helicobacter pylori and anti-inflammatory activities. Thus, this prescription may be a suitable natural source for the prevention and treatment of chronic gastritis and gastric ulcers.

    The prevalence of Helicobacter pylori-negative and nonsteroidal anti-inflammatory drug-negative peptic ulcers, commonly known as idiopathic peptic ulcers (IPUs), has been reported to be very low (0.9-2.6%) in Japan based on data from the 1990s. However, recent trends have yet to be been reported. Herein, we present a multicenter prospective analysis between 2012 and 2013 investigating current trends in the prevalence and characteristics of IPUs in Japan. Clinical data of all peptic ulcer subjects detected via endoscopy at four participating hospitals were prospectively collected between April 2012 and March 2013. Enrolled subjects were classified according to H. pylori infection status and intake of nonsteroidal anti-inflammatory drugs. Multiple logistic regression analyses were used to determine the risk factors for IPUs. Of 382 enrolled patients with peptic ulcers, 46 (12%) were judged to have IPUs. Compared with those with simple H. pylori-positive ulcers, patients with IPUs were significantly older (P < 0.02) and more often had underlying comorbidities such as hypertension (P < 0.02) and hyperlipidemia (P < 0.05). Multivariate regression analysis indicated that the presence of multiple underlying diseases was the only significant risk factor for IPUs, with an odds ratio of 3.8 (95% confidence interval, 1.3-11.1). This study revealed that the prevalence of IPUs in patients with peptic ulcers in Japan is 12%, much higher than previously reported. Presence of multiple underlying comorbid diseases, rather than aging itself, is an important risk factor for IPUs. © 2014 Journal of Gastroenterology and Hepatology Foundation and Wiley Publishing Asia Pty Ltd.

    We aimed to identify the signals that indicate the possible benefits of administering Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) at the initiation of meal, compared to immediately after food. This was a randomized, controlled, pilot study in 160 patients who received only NSAIDs for various pain conditions. Patients were randomized to Group I (control group) -NSAID After Food (AF), Group II-NSAID Before Food (BF), Group III-NSAID BF for 2 days and then crossed over to AF for next two days (CO-1) and Group IV-NSAID AF for 2 days and then crossed over to BF for next two days (C0-2 group). Group III & Group IV were given a washout period of 48 hours after the initial two days of treatment. All were followed up for the next 2 drug free days. Patients were observed for the development of gastritis (epigastric distress, epigastric pain, nausea, fullness of stomach, repeated reflux) throughout the study. Symptoms of gastritis were seen in 6.45% (2/31) and 36.11% (13/36) patients in group I and II, respectively. There was no statistically significant difference in the development of gastritis in AF group. However, statistically significant difference (Pgastritis. Administering NSAIDs at the initiation of meal is better tolerated as indicated by the lower incidence of gastritis. If proved in larger population, routine concurrent administration of medication for prevention of gastritis can be avoided.

    In order to elucidate the contribution of cycloxygenase (COX) enzymes in the anti-oxidant and anti-inflammatory mechanisms of nesfatin-1, which improves the healing process of chronic gastric ulcers, either acetic acid (80%; ulcer groups; n = 40) or saline (control groups; n = 40) was applied to the serosal surface of male Sprague Dawley rats' stomachs for 1 min. Both the control and ulcer groups were treated daily with either i.p. saline or nesfatin-1 (0.3 μg/kg; for 3 days). Nesfatin-1-treatment was preceded with i.p. saline, COX-2 inhibitor NS-398 (2 mg/kg), COX-1 inhibitor ketorolac (3 mg/kg) or non-selective COX inhibitor indomethacin (5 mg/kg) for 3 days. The rats were decapitated at the end of the third day, and their trunk blood was collected for the measurements of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β) and IL-10 using ELISA. The induction of ulcers resulted in increased macroscopic scores, along with elevated gastric malondialdehyde, luminol- and lucigenin-enhanced chemiluminescence levels and myeloperoxidase activity. On the other hand, nesfatin-1 treatment abolished these elevations. Depleted glutathione, superoxide dismutase and catalase activity levels in the saline-treated ulcer group were preserved in the nesfatin-1-treated ulcer group. Increased levels of serum TNF-α, IL-1β, IL-10 in the saline-treated ulcer group, as compared to control group, were significantly decreased in the nesfatin-1-treated ulcer group. The inhibition of COX-1, and/or COX-2 reversed most of the alterations induced with nesfatin-1, but COX-2-blockade was consistently more effective to abolish all nesfatin-1-induced changes. Our results suggest that nesfatin-1 ameliorates ulcer-induced inflammatory response through the modulation of oxidant-antioxidant balance. As selective pharmacological inhibition of COX-1 or COX-2 suppresses the antioxidant/anti-inflammatory effects of nesfatin-1, it appears that nesfatin-1 decreases inflammatory mediators and

    BACKGROUND Although Helicobacter pylori and non-steroidal anti-inflammatory drugs (NSAIDs) are the main causes of peptic ulcers disease (PUD), recently the prevalence of idiopathic peptic ulcer (IPU) is increasing in most parts of the world. The aim of this study was to assess the prevalence of IPU in Kerman, the center of largest province in south-east Iran. METHODS We included 215 patients with peptic ulcer in our study. Combined methods rapid urease test (RUT), histology, and real time polymerase chain reaction (PCR) was performed on endoscopic samples of peptic ulcers. NSAID use was determined by medical history. SPSS software version 16 was used for data analysis. p valuepeptic ulcer, four (1.8%) had H.pylorinegative and NSAID-negative PUD. There were not significant differences between patients with IPU and patients with peptic ulcer associated with H.pylori or NSAIDs regarding the sex, age, cigarette smoking, and opioid abuse. CONCLUSION Our study showed that in contrast to other reports from western and some Asian countries, the prevalence of IPU is low in Kerman and H.pylori infection is still the major cause of PUD. We recommend a large and multi-central study to determine the prevalence of IPU in Iran.

METHODS: We collected blood samples and psychological, social, behavioral, and medical data in 1982-1983 from a population-based sample of 3379 Danish adults without a history of ulcer participating in the World Health Organization's MONICA study. A 0- to 10-point stress index scale was used......BACKGROUND & AIMS: There is controversy over whether psychological stress contributes to development of peptic ulcers. We collected data on features of life stress and ulcer risk factors from a defined population in Denmark and compared these with findings of confirmed ulcers during the next 11...... to measure stress on the basis of concrete life stressors and perceived distress.

    Gastric ulcers (GUs) are a common type of peptic ulcer. Alcohol overdose is one of the main causes of GU, which is difficult to prevent. Although the protective effect of butyrate on inflammation-related diseases is well understood, its effect on GUs has not been reported. We investigated the protective effects of butyrate against ethanol-induced lesions to the gastric mucosa in mice and the underlying mechanisms. BALB/c mice were orally pretreated with butyrate for 30min prior to the establishment of the GU model by challenge with absolute ethanol. Ethanol administration produced apparent mucosal injuries with morphological and histological damage, whereas butyrate pretreatment reduced the gastric mucosal injuries in a dose-dependent manner. Butyrate pretreatment also significantly ameliorated contents of malondialdehyde (MDA) and carbonyl proteins, and decreased levels of IL-1β, TNF-α and IL-6. The Western blot results consistently demonstrated that butyrate pretreatment attenuated the phosphorylation of NF-κB p65, p38 MAPK and ERKs in the gastric tissues. Additionally, gastric wall mucus (GWM), a parameter reflecting mucosal defense, was clearly increased by butyrate pretreatment. Butyrate pretreatment protects the gastric mucosa against ethanol-induced lesions by strengthening the mucosal defense and anti-oxidant and anti-inflammatory activities. As a necessary substance for the body, butyrate may be applied to the prevention and treatment of GUs. Copyright © 2015 Elsevier B.V. All rights reserved.

    Non-steroidal anti-inflammatory drugs (NSAIDs) are an effective and common treatment for chronic pain disorders, but long-term use is associated with risk of potentially life-threatening gastrointestinal adverse events (AEs). The proton pump inhibitor esomeprazole has been found to be effective for gastroprotection in NSAID users, but few long-term studies have been conducted in Japan. This was an open-label, multicentre, single-arm, prospective 1-year study of treatment with esomeprazole (20 mg once daily) in Japanese patients (aged ≥20 years) with endoscopic evidence of previous peptic ulcer and receiving daily oral NSAID therapy (at a stable dose) for a chronic condition. Eligibility was not dictated by type of oral NSAID. The primary objective was to determine long-term safety and tolerability of esomeprazole. Efficacy for prevention of peptic ulcers was also determined (Kaplan-Meier method). All statistical analyses were descriptive. A total of 130 patients (73.1% women, mean age 62.1 years, 43.8% Helicobacter pylori-positive) received treatment with esomeprazole in addition to long-term NSAID therapy (most commonly for rheumatoid arthritis [n=42] and osteoarthritis [n=34]). Loxoprofen, meloxicam and diclofenac were the most commonly used NSAIDs; cyclo-oxygenase (COX)-2 selective agents were used by 16.2% of patients (n=21). Long-term compliance with esomeprazole (capsule counts) was >75% for the majority of patients. Although 16.9% of patients (n=22) experienced AEs judged to be possibly related to treatment with esomeprazole, they were mostly mild and transient. The most commonly reported possibly treatment-related AEs were abnormal hepatic function, headache, increased γ-glutamyltransferase levels and muscle spasms (2 patients each). Overall, 95.9% (95% confidence interval: 92.3, 99.4) of patients remained ulcer free at 1 year. Long-term treatment with esomeprazole (20 mg once daily) is well tolerated and efficacious for preventing ulcer recurrence in

    Ulcerative colitis (UC) is a chronic inflammatory disease affecting colon. The primary symptoms of UC are diarrhoea with blood and mucus and sometimes associated with pain. This study aimed to evaluate the effects of diosmin (DIO) on UC. UC was induced in rats by rectal administration of acetic acid (AA). The degree of mucosal ulceration and damage was determined by evaluating the disease activity index (DAI) and colon damage index scores. Inflammation, oxidative stress and apoptotic responses were determined by measuring the levels of tumour necrosis factor-α (TNF-α), cyclooxygenase-2 (COX-II), malondialdehyde (MDA) and reduced glutathione (GSH) in addition to myeloperoxidase (MPO) activity and caspase-3 expression. The results of this study indicate that AA caused increase in DAI and colon damage index scores. Also, markers of inflammation (TNF-α, COX-II and MPO) and oxidative stress (MDA and reduced GSH) were significantly elevated. These changes were associated with increases in colon caspase-3 expression. Treatment of rats with two doses of DIO produced a dose-dependent decline in DAI and colon damage index scores. Also, DIO resulted in significant reduction of inflammatory and oxidative stress markers as well as reduced the expression of caspase-3. DIO therapy decreased UC development depending on its ability to decreases inflammation, oxidative stress and apoptosis in rat colon.

    Full Text Available Ulcers are common symptoms observed in the oral cavity and some ulcerations are induced by drug medications. When ulcers show typical clinical findings differential diagnosis may be easy, but the exact diagnosis is often difficult. We reviewed differential diagnosis of oral ulcerative diseases, clinical characteristics of drug-induced oral ulcerations and drugs inducing oral ulcerations. Many kinds of drugs have been reported to cause oral ulcerations. Among them, non-steroidal anti-inflammatory drugs are popular and well-known. However, several recent reports have described oral ulceration associated with relatively new drugs for the treatment of chronic disorders such as, diabetes, angina pectoris, rheumatoid arthritis, and osteoporosis. We reviewed these new drugs and also reported typical cases of drug-induced oral ulcerations.

    Helicobacter pylori-negative and non-steroidal anti-inflammatory drugs (NSAIDs)-negative idiopathic peptic ulcers (IPU) have attracted attention in Japan and other developed countries. The aim of the present study was to clarify the healing rate of IPU and the risk of recurrence. We conducted a retrospective follow-up study of patients with peptic ulcer disease (PUD) who were diagnosed in our previous multicenter-prospective study. Three hundred and eighty-two patients from four institutions in the Tohoku district were enrolled. Enrolled subjects were divided into four groups according to H. pylori infection and intake of NSAIDs. In these patients, we checked treatment course, healing rate during 3 months, and recurrence rate. Healing rates in the: (i) simple H. pylori group; (ii) H. pylori (+)/ NSAIDs (+) group, (iii) simple NSAIDs group; and (iv) IPU group, were 95.0%, 94.9%, 73.3%, and 77.4%, respectively. The healing rate of the IPU group was significantly lower than that of both the simple H. pylori group and the H. pylori (+)/ NSAIDs (+) group (P < 0.01). The recurrence rate of 13.9% in the IPU group was much higher than the 2.1% in the simple H. pylori group (P < 0.01). Additionally, the cumulative recurrence rates by the Kaplan-Meier method in the IPU group were significantly higher than those of the simple H. pylori group (P = 0.015). We demonstrated that the clinical course of peptic ulcers is considerably different depending on the cause. IPU could be refractory to treatment and prone to recur compared with simple H. pylori ulcers. © 2016 Japan Gastroenterological Endoscopy Society.

    A histamine-2 receptor antagonist (H2RA) is one of the common gastroprotective co-therapies used with non-steroidal anti-inflammatory drugs (NSAIDs) for the prevention or treatment of peptic ulcers (PUs). To date, no study has directly compared the prophylactic effectiveness between high-dose and low-dose H2RA. Our objective was to compare the effectiveness of high-dose versus low-dose H2RAs in the primary prophylaxis of PUs among short-term NSAID users. A retrospective cohort study was conducted using the Clinical Data Analysis and Reporting System (CDARS) in Hong Kong. Patients aged 18 years or above who received a single prescription of oral NSAID with oral H2RA were identified within the study period (1 January 2009-31 December 2012). Patients with a history of or risk factors for PU in the corresponding 2 years prior to the index date (of the first NSAID prescription) were excluded. Log binomial regression analysis was used to calculate the relative risk of PU among NSAID users with high-dose H2RA versus low-dose H2RA exposure. Among the NSAID cohort (n = 102,042), 77,509 (76 %) were on low-dose H2RA and 24,533 (24 %) were on high-dose H2RA. Of the total 69 PU cases identified during the drug exposure period, 64 (0.08 %) received low-dose-H2RA and five (0.02 %) received high-dose H2RA. The overall absolute risk of PUs for NSAID users whilst on H2RA was approximately 1 per 1,479 patients. The adjusted relative risk for NSAID users receiving high-dose H2RA versus low-dose H2RA was 0.32 (95 % confidence interval [CI] 0.13-0.79). Patients aged ≥65 years, receiving a longer duration of treatment, or with concomitant use of antiplatelet agents were found to be at higher risk of PU. High-dose H2RA showed greater effectiveness than low-dose H2RA in the primary prophylaxis of NSAID-associated PUs in short-term new users.

    Low-dose lansoprazole has not been intensively evaluated for its efficacy in the prevention of recurrent gastric or duodenal ulcers in patients receiving long-term non-steroidal anti-inflammatory drug (NSAID) therapy for pain relief in such diseases as rheumatoid arthritis, osteoarthritis, and low back pain. This multi-center, prospective, double-blind, randomized, active-controlled study involving 99 sites in Japan was designed to compare the efficacy of lansoprazole (15 mg daily) with gefarnate (50 mg twice daily). Patients with a history of gastric or duodenal ulcers who required long-term NSAID therapy were randomized to receive lansoprazole 15 mg daily (n = 185) or gefarnate 50 mg twice daily (n = 181) and followed up for 12 months or longer prospectively. The cumulative incidence of gastric or duodenal ulcer at days 91, 181, and 361 from the start of the study was calculated by the Kaplan-Meier method as 3.3, 5.9, and 12.7%, respectively, in the lansoprazole group versus 18.7, 28.5, and 36.9%, respectively, in the gefarnate group. The risk for ulcer development was significantly (log-rank test, P lansoprazole group than in the gefarnate group, with the hazard ratio being 0.2510 (95% CI 0.1400-0.4499). A long-term follow-up study showed an acceptable safety profile for low-dose lansoprazole therapy, with diarrhea as the most frequent adverse event. Lansoprazole was superior to gefarnate in reducing the risk of gastric or duodenal ulcer recurrence in patients with a definite history of gastric or duodenal ulcers who required long-term NSAID therapy.

    Portulaca oleracea L., (POL) is one of commonly used medicine-food herbs and has a cosmopolitan distribution in many countries. Many studies showed that POL exhibited a wide range of pharmacological effects such as anti-inflammatory and liver complaints. In the clinical studies, POL was usually used for the treatment of UC disease and the clinical efficacy was well, but the mechanism and scientific intension was still unknown. In the present study, we studied the protective effects of the ethanol extract from POL on dextran sulphate sodium-induced UC in C57BL/6 mice model through oxidative stress and inflammatory pathway. The results demonstrated that the ethanol extract from POL could exhibit the effective protection for the DSS induced UC by increasing the colon length, decreasing body weight loss and the disease activity index score, inhibiting oxidative stress response through the MDA, NO, SOD activities, reducing the mRNA expressions of pro-inflammatory cytokines (TNF-α, IL-1β and IL-6) and the protein expressions of TNF-α and NF-kB p65. These results may prove that POL could be considered as a useful and effective botanical compound from the edible plant to be used in UC through the oxidative stress and inflammatory activities.

    The associations between antithrombotic or antihypertensive drugs and peptic ulcer bleeding (PUB) remain unknown, particularly in Asia, where Helicobacter pylori infection is prevalent. This study aims to evaluate the risks of PUB from antithrombotic drugs, angiotensin II receptor blockers (ARBs), angiotensin-converting enzyme (ACE) inhibitors, calcium channel blockers, α-blockers, and β-blockers. This prospective hospital-based case-control study included 230 patients with endoscopically verified PUB and 920 age and sex-matched controls (1:4) without bleeding on screening endoscopy. Adjusted odds ratios (AOR) for the risk of PUB were determined by conditional logistic regression analysis. In multivariate analysis, alcohol consumption (AOR, 2.2; P history of peptic ulcer (AOR, 4.8; P pylori infection (AOR, 2.1; P pylori eradication (AOR, 0.03; P pylori infection and NSAIDs use for PUB (P = 0.913). ARBs (P = 0.564), ACE inhibitors (P = 0.213), calcium channel blockers (P = 0.215), α-blockers (P = 0.810), and β-blockers (P = 0.864) were not associated with PUB. We found that alcohol consumption, history of peptic ulcer, H. pylori infection, NSAIDs use, and low-dose aspirin use were independent risk factors for PUB, whereas H. pylori-eradication, PPIs use, and H2RA use reduced its risk. Interactions between H. pylori and NSAIDs use in PUB were not observed. No antihypertensive drug was associated with PUB. © 2014 Journal of Gastroenterology and Hepatology Foundation and Wiley Publishing Asia Pty Ltd.

    With the observation that cupric acetate had anti-inflammatory activity in the foot edema model of inflammation, it was felt that copper may play a role as a component of the active metabolite of anti-inflammatory agents used clinically. To test this hypothesis, various Cu chelates were made and tested in the foot edema, cotton-wad granuloma and polyarthritis models of inflammation. A marked increase in anti-inflammatory activity has been observed for the Cu chelates of chelating agents that had no anti-inflammatory activity as well as those that have been used clinically. Since ulcers may be viewed as inflammatory processes and often associated with the arthritic disease syndrome, the Cu chelates were evaluated as anti-ulcer agents. These compounds were demonstrated to have anti-ulcer activity in the Shay as well as the corticoid and stress induced rat ulcer models. Mechanistic considerations relevant to lysosomal and digestive proteolytic enzyme inhibition, anti-cholinergic activity, prostaglandin synthesis and wound healing are discussed. 9 references, 3 figures, 3 tables.

    Hyperkalemia is a common clinical condition that can be defined as a serum potassium concentration exceeding 5.0 mmol/L. Drug-induced hyperkalemia is the most important cause of increased potassium levels in everyday clinical practice. Drug-induced hyperkalemia may be asymptomatic. However, it may be dramatic and life threatening, posing diagnostic and management problems. A wide range of drugs can cause hyperkalemia by a variety of mechanisms. Drugs can interfere with potassium homoeostasis either by promoting transcellular potassium shift or by impairing renal potassium excretion. Drugs may also increase potassium supply. The reduction in renal potassium excretion due to inhibition of the renin-angiotensin-aldosterone system represents the most important mechanism by which drugs are known to cause hyperkalemia. Medications that alter transmembrane potassium movement include amino acids, beta-blockers, calcium channel blockers, suxamethonium, and mannitol. Drugs that impair renal potassium excretion are mainly represented by angiotensin-converting enzyme inhibitors, angiotensin-II receptor blockers, direct renin inhibitors, nonsteroidal anti-inflammatory drugs, calcineurin inhibitors, heparin and derivatives, aldosterone antagonists, potassium-sparing diuretics, trimethoprim, and pentamidine. Potassium-containing agents represent another group of medications causing hyperkalemia. Increased awareness of drugs that can induce hyperkalemia, and monitoring and prevention are key elements for reducing the number of hospital admissions, morbidity, and mortality related to drug-induced hyperkalemia.

    2008-09-03

    Diarrhea is a frequent adverse event involving the most frequently antibiotics, laxatives and NSAI. Drug induced diarrhea may be acute or chronic. It may be due to expected, dose dependant properties of the drug, to immuno-allergic or bio-genomic mechanisms. Several pathophysiological mechanisms have been described resulting in osmotic, secretory or inflammatory diarrhea, shortened transit time, or malabsorption. Histopathological lesions sometimes associated with drug induced diarrhea are usually non specific and include ulcerations, inflammatory or ischemic lesions, fibrous diaphragms, microscopic colitis and apoptosis. The diagnosis of drug induced diarrhea, sometimes difficult to assess, relies on the absence of other obvious causes and on the rapid disappearance of the symptoms after withdrawal of the suspected drug.

    To evaluate the anti-inflammatory intestinal effect of the ethanolic extract (EtOHE) and hexane phase (HexP) obtained from the leaves of Combretum duarteanum ( Cd ). Inflammatory bowel disease was induced using trinitrobenzenesulfonic acid in acute and relapsed ulcerative colitis in rat models. Damage scores, and biochemical, histological and immunohistochemical parameters were evaluated. Both Cd -EtOHE and Cd -HexP caused significant reductions in macroscopic lesion scores and ulcerative lesion areas. The vegetable samples inhibited myeloperoxidase increase, as well as pro-inflammatory cytokines TNF-α and IL-1β. Anti-inflammatory cytokine IL-10 also increased in animals treated with the tested plant samples. The anti-inflammatory intestinal effect is related to decreased expression of cyclooxygenase-2, proliferating cell nuclear antigen, and an increase in superoxide dismutase. The data indicate anti-inflammatory intestinal activity. The effects may also involve participation of the antioxidant system and principal cytokines relating to inflammatory bowel disease.

    Inflammation is a manifestation of a wide range of disorders which include; arthritis, atherosclerosis, Alzheimer’s disease, inflammatory bowel syndrome, physical injury and infection amongst many others. Common treatment modalities are usually non-steroidal anti-inflammatory drugs (NSAIDs) such as aspirin, paracetamol, indomethacin and ibuprofen as well as corticosteroids such as prednisone. These however, may be associated with a host of side effects due to non-selectivity for cyclooxygenase (COX) enzymes involved in inflammation and those with selectivity may be highly priced. Thus, there is a continuing search for safe and effective anti-inflammatory molecules from natural sources. Research has confirmed that iridoids exhibit promising anti-inflammatory activity which may be beneficial in the treatment of inflammation. Iridoids are secondary metabolites present in various plants, especially in species belonging to the Apocynaceae, Lamiaceae, Loganiaceae, Rubiaceae, Scrophulariaceae and Verbenaceae families. Many of these ethnobotanicals have an illustrious history of traditional use alluding to their use to treat inflammation. Although iridoids exhibit a wide range of pharmacological activities such as cardiovascular, hepatoprotection, hypoglycaemic, antimutagenic, antispasmodic, anti-tumour, antiviral, immunomodulation and purgative effects this review will acutely focus on their anti-inflammatory properties. The paper aims to present a summary for the most prominent iridoid-containing plants for which anti-inflammatory activity has been demonstrated in vitro and / or in vivo. PMID:22414102

    Over the past two decades, it has become well accepted that sepsis exhibits two, oftentimes concomitant, inflammatory stages; a pro-inflammatory phase, referred to as the systemic inflammatory response syndrome (SIRS), and an anti-inflammatory phase, called the compensatory anti-inflammatory response syndrome (CARS). Considering that therapeutic interventions designed to attenuate the pro-inflammatory septic response have generally failed, much recent research has gone into understanding how and why septic patients display immunosuppressive characteristics, what the significance of septic immunosuppression may be and if there exists any therapeutic targets within the CARS. Herein, we describe the potential mechanisms of the immunosuppressive/CARS phase of sepsis by discussing what anti-inflammatory agents, receptors and cell populations are currently believed to contribute to CARS.

    Objectives: Aim of the present work was to investigate the anti-inflammatory, analgesic and antiulcer effects of red seaweed Porphyra vietnamensis (P. vietnamenis). Materials and Methods: Aqueous (POR) and alcoholic (PE) fractions were successfully isolated from P. vietnamenis. Further biological investigations were performed using a classic test of paw edema induced by carrageenan, writhing induced by acetic acid, hot plate method and naproxen induced gastro-duodenal ulcer. Results: Among the fractions POR showed better activity. POR and PE significantly (p < 0.05) reduced carrageenan induced paw edema in a dose dependent manner. In the writhing test POR significantly (p < 0.05) reduced abdominal writhes than PE. In hot plate method POR showed better analgesic activity than PE. POR showed comparable ulcers reducing potential (p<0.01) to that of omeprazole, and has more ulcer reducing potential then PE. Conclusions: The results of this study demonstrated that P. vietnamenis aqueous fraction possesses biological activity that is close to the standards taken for the treatment of peripheral painful or/and inflammatory and ulcer conditions.

  12. Anti-inflammatory responses of resveratrol.

    Das, Samarjit; Das, Dipak K

    2007-09-01

    Resveratrol (trans-3,4',5-trihydroxystilbene), a natural polyphenolic, non-flavonoid antioxidant, is a phytoalexin found in many plants including grapes, nuts and berries. Recent studies have documented that resveratrol has various health benefits, such as cardiovascular and cancer preventive properties. However, the experimental basis for such health benefit is not fully understood. One of the possible mechanisms for its protective activities is by down regulation of the inflammatory responses. That includes the inhibition of synthesis and release of pro-inflammatory mediators, modifications of eicosanoid synthesis, inhibition of some activated immune cells, or inhibiting the enzymes, such as cyclooxygenase-1 (COX-1) or cyclooxygenase-2 (COX-2), which are responsible for the synthesis of pro-inflammatory mediators through the inhibitory effect of resveratrol on transcription factors like nuclear factor kappaB (NFkappaB) or activator protein-1 (AP-1). Being a phenolic compound, resveratrol certainly possesses a low bioavailability and most importantly, a rapid clearance from the plasma. Recent growing interest in varying protective nature of resveratrol may clinically also hold a respectable position as a better alternative for anti-inflammatory drugs. The purpose of this review is to provide evidence that resveratrol exhibits potent anti-inflammatory activity and also to explain the underling mechanism for both resveratrol- induced cardioprotective and anti-inflammatory properties. While it is true that the cardioprotective properties of resveratrol are likely attributable, at least in part, to its anti-inflammatory properties, the mechanisms discussed address foremost mechanisms for the anti-inflammatory activity which, in turn, is responsible for cardioprotection.

Natural products play a significant role in human health in relation to the prevention and treatment of inflammatory conditions. Further studies are being conducted to investigate the mechanism of action, metabolism, safety and long term side effect of these natural products, as well as interactions between these natural products with food and drug components.

  14. Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) Induced Dyspepsia.

    Science.gov (United States)

    Yap, Paul Ray-Yee; Goh, Khean-Lee

    2015-01-01

    Non-steroidal anti-inflammatory drugs (NSAIDs) are the most prescribed group of drugs in the world. They are used primarily for pain relief in chronic inflammatory joint disease and act by inhibiting enzymes COX1 and COX2 and ultimately preventing the production of active prostanoids which are required for the innate inflammatory pathway. The use of NSAIDs have been associated with the development of gastrointestinal (GI) symptoms ranging from simple dyspepsia to life threatening GI bleeds and perforations. The definition of dyspepsia has evolved over the years and this has hampered accurate studies on the prevalence of dyspepsia as different studies used varying criteria to define dyspepsia. It is now known that NSAIDs significantly increase the risk of dyspepsia.The risk of developing peptic ulcer disease vary with specific NSAIDs and dosages but there is no correlation between the symptoms of dyspepsia and underlying peptic ulcers. The pathogenesis of dyspepsia with NSAIDs is not completely understood. Peptic ulceration alone is not able to account for the majority of dyspepsia symptoms encountered by NSAIDs users. Erosive oesophagitis secondary to NSAIDs may be contributing factor to the prevalence of dyspepsia in NSAIDs users. Altered gut permeability and changes in gastric mechanosensory function due to NSAIDs may also be a contributory factor. Management of NSAID induced dyspepsia is involves a multipronged approach. Drug avoidance if possible would be ideal. Other options include using the lowest effective dose, changing to an NSAIDs with a safer GI risk profile, avoiding concurrent use with other NSAIDs or if the patient has a previous history of peptic ulcer disease, and co-prescribing with anti-secretory medications such as proton pump inhibitors. Eradication of Helicobacter pylori has a protective role against developing peptic ulcers and may also improve symptoms of NSAIDs induced dyspepsia.

    Full Text Available Coronary artery disease, in the development of which inflammation mediated by innate immune cells plays a critical role, is one of the leading causes of death worldwide. The 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors (statins are a widely used lipid-lowering drug that has lipid-independent vasculoprotective effects, such as improvement of endothelial dysfunction, antioxidant properties, and inhibitory effects on inflammation. Despite recent advances in lipid-lowering therapy, clinical trials of statins suggest that anti-inflammatory therapy beyond lipid-lowering therapy is indispensible to further reduce cardiovascular events. One possible therapeutic option to the residual risk is to directly intervene in the inflammatory process by utilizing a nanotechnology-based drug delivery system (nano-DDS. Various nano-sized materials are currently developed as DDS, including micelles, liposomes, polymeric nanoparticles, dendrimers, carbon nanotubes, and metallic nanoparticles. The application of nano-DDS to coronary artery disease is a feasible strategy since the inflammatory milieu enhances incorporation of nano-sized materials into mononuclear phagocytic system and permeability of target lesions, which confers nano-DDS on “passive-targeting” property. Recently, we have developed a polymeric nanoparticle-incorporating statin to maximize its anti-inflammatory property. This statin nanoparticle has been tested in various disease models, including plaque destabilization and rupture, myocardial ischemia-reperfusion injury, and ventricular remodeling after acute myocardial infarction, and its clinical application is in progress. In this review, we present current development of DDS and future perspective on the application of anti-inflammatory nanomedicine to treat life-threatening cardiovascular diseases.

Hexane extract showed to be inactive, but the ethanol extract at doses of 400 mg/kg produced significant inhibition of carrageenan-induced paw oedema and reduced the weight of cotton pellet-induced granuloma, moreover, the topical application of 0.5 mg/ear of this extract inhibited the edema induced with TPA by 49.13%, an effect which is of less intensity than that produced by indomethacine at the same dose.

  19. Erdosteine: antitussive and anti-inflammatory effects.

    Science.gov (United States)

    Dal Negro, Roberto W

    2008-01-01

    Erdosteine is a multifactorial drug currently used in COPD for its rheologic activity on bronchial secretions and its positive effects on bacterial adhesiveness. Erdosteine produces an active metabolite (Met 1) which was shown to produce antioxidant effects during the respiratory burst of human PMNs, due to the presence of an SH group. The substantial antitussive effects of erdosteine were first documented in clinical trials even though mucolytic agents are regarded as not consistently effective in ameliorating cough in patients with bronchitis, although they may be of benefit to this population in other ways. Actually, a mucolytic drug could exert antitussive effects if it also affects mucus consistency and enhances ciliary function. In the last decade, data from several studies on animal models pointed to the possible antitussive and anti-inflammatory properties of erdosteine and an indirect anti-inflammatory mechanism of action was suggested. Recently, data from some controlled versus placebo studies documented the antioxidant properties of erdosteine in humans and in current smokers with COPD. The mechanism of action was described as related to erdosteine's ability to inhibit some inflammatory mediators and some pro-inflammatory cytokines that are specifically involved in oxidative stress. As oxidative stress is also presumed to impair beta-adrenoceptor function and contribute to airway obstruction, specific controlled studies recently investigated the effect of antioxidant intervention on short-term airway response to salbutamol in nonreversible COPD, according to a double-blind design versus placebo and NAC. Only erdosteine consistently restored a significant short-term reversibility in COPD subjects, previously unresponsive to beta(2) adrenergics. This peculiar activity of erdosteine (to our knowledge never previously assessed) proved related to the ROS scavenging activity (which actually proved equal to that of N), and its significant inhibiting effect on

    2016-01-01

    Non-steroidal anti-inflammatory drugs (NSAIDS) are clinically used as anti-inflammatory, analgesic and antipyretic agents but they have the drawbacks such as gastric irritation and gastric ulceration. Recently, quinoline derivatives have shown significant anti-inflammatory and less ulcerogenic activity. The present study deals with the synthesis and pharmacological assessment of a series of novel quinoline derivatives bearing azetidinones scaffolds as anti-inflammatory and analgesic agents. A series of newer 3-chloro-1-(substituted)-4-(tetrazolo [1,5-a]quinolin-4- yl)azetidin-2-one derivatives (6a-l) was synthesized starting with acetanilide (1). Initially, acetanilide (1) was allowed to react with Vilsmeier-Haack reagent (DMF + POCl3) to form 2- chloro-3-formyl quinoline (2). The 2-chloro-3-formyl quinoline (2) was further treated with p-toluenesulphonic acid and sodium azide which yielded Tetrazolo [1,5-1] quinoline-4- carbaldehyde (3). The reaction of formyl group with various substituted amines (4a-l) formed corresponding Schiff base intermediates (5a-l), which were further allowed to react with chloroacetyl chloride to produce 3-chloro-1-(substituted)-4-(tetrazolo [1,5-a]quinolin-4-yl) azetidin-2-one derivatives (6a-l). The structure of the final analogues (6a-l) has been confirmed on the basis of elemental analysis, IR, 1H NMR, 13C NMR and mass spectra. All the synthesized compounds were evaluated for their anti-inflammatory and analgesic activities by using carrageenan induced rat paw model and Eddy's hot plate method respectively. All the values of elemental analysis, IR, 1H NMR, 13C NMR and mass spectra were found to be prominent. The anti-inflammatory activity test revealed that 3-chloro-1-(4-methoxyphenyl)- 4-(tetrazolo[1,5-a] quinolin-4-yl)azetidin-2-one (6b), 3-chloro-1-(2-methoxyphenyl)- 4-(tetrazolo[1,5-a]quinolin-4-yl)azetidin-2-one (6a) exhibited significant anti-inflammatory and analgesic activity as compared to control group.

    2013-04-01

    Silk sericin was found to suppress the production of pro-inflammatory cytokines, which are related to the inflammatory reaction. The objectives of this study were to investigate the anti-inflammatory effect of sericin in vivo using the carrageenan-induced rat edema model and changes in the histology of tissues. The effects of sericin on the expression of COX-2 and iNOS were also evaluated. Sericin solutions at 0.004-0.080 mg/mL were applied topically to the top of the hind paw and carrageenan (1.0 mg) was injected subcutaneously to the plantar surface of the right hind paw. Our results indicated that sericin significantly reduced the inflammation in rats' paw compared with the negative control (water and acetone) and its effect at 0.080 mg/mL was only slightly lower than that of 1.0% w/v indomethacin. Similar numbers of polymorphonuclear and macrophage cells were found in rats' tissue treated with indomethacin and sericin solution, while the numbers were significantly higher in their absence. The gene expression results by RT-PCR showed that the COX-2 and iNOS genes were down-regulated in samples treated with sericin in a dose dependent manner. These data indicated that the anti-inflammatory properties of sericin may be partly attributable to the suppression of the COX-2 enzyme and nitric oxide production.

    1999-01-01

    Full Text Available Nonsteroidal anti-inflammatory drug (NSAID use has increased dramatically in the past two decades. A large proportion of the elderly population (more than 65 years of age holds a current or recent NSAID prescription, accounting for approximately 90% of all NSAID prescriptions. Despite studies that advise finding alternatives for NSAIDs for the management of osteoarthritis, physicians often prescribe NSAIDs first for such common musculoskeletal conditions. Despite being identified as risk factors for gastrointestinal complications, the simultaneous use of two NSAIDs and the coadministration of NSAIDs with corticosteroids and with coumadin continue to occur. The point prevalence of NSAID-induced ulcers is 10% to 30%, and 15% to 35% of all peptic ulcer complications are caused by NSAIDs. The increased risk of gastrointestinal complications when NSAIDs are used is 3% to 5%. This risk increases with other identified risk factors (eg, older age, previous gastrointestinal history, comorbid diseases and poor health. Gastrointestinal causes of hospitalization (eg, gastrointestinal hemorrhage and perforation and death have increased in parallel to increased NSAID use. ‘Antiulcer’ agents are prescribed twice as often in NSAID users, and the economic impact (eg, diagnostic tests and hospitalization is that about one-third of the arthritis budget has been dedicated to deal with gastrointestinal side effects of NSAIDs. Misoprostol and omeprazole have been shown to be cytoprotective for the gastroduodenal mucosa when NSAIDs are used, and misoprostol has been shown to reduce the risk of gastroduodenal ulcer complications. Economic evaluations have suggested that these agents are a cost effective means of dealing with such NSAID-associated problems. Although no NSAID is totally safe, a number of studies have demonstrated that NSAIDs may be ranked according to relative gastrointestinal toxicity.

    2013-01-01

    Strophanthus hispidus DC (Apocynaceae) is a medicinal plant widely used in traditional African medicine in the treatment of rheumatic afflictions, ulcer, conjunctivitis, leprosy and skin diseases. This study sought to investigate the antinociceptive, anti-inflammatory and antiulcer properties of the ethanol root extract of S. hispidus. Antinociceptive activity was evaluated using acetic acid-induced writhing and formalin tests in mice. The carrageenan- and egg albumin-induced rat paw edema tests were used to investigate the anti-inflammatory actions, whereas the antiulcer activity was investigated using ethanol-, HCl- and pyloric ligation-induced gastric ulcer models in rats. S. hispidus [100-800 mg/kg orally (po)] produced significant (p<0.05) inhibition of writhing reflex with peak effect of 74.13% inhibition observed at 800 mg/kg. Similarly, S. hispidus significantly (p<0.05) attenuated formalin-induced early and late phase of nociception with peak effect of 61.84% and 89.43%, respectively, at 200 mg/kg. S. hispidus (25-800 mg/kg po) caused significant (p<0.05) inhibition of edema development in the carrageenan and egg albumin models with peak effect (93.40% and 90.10% inhibition of edema formation) observed at 50 mg/kg. With respect to antiulcer activity, S. hispidus (100-800 mg/kg) showed potent antiulcer activity with respective peak effects of 96% (ethanol-induced), 99% (HCl-induced) and 70.60% inhibition of ulcer. The findings in this study suggest that the ethanol root extract of S. hispidus possesses antinociceptive, anti-inflammatory and antiulcerogenic activities. This justifies the use of the extract in folklore medicine for the treatment of ulcer and inflammatory disorders.

    2016-07-01

    Chronic inflammation is linked with the generation and progression of various diseases such as cancer, diabetes and atherosclerosis, and anti-inflammatory drugs therefore have the potential to assist in the treatment of these conditions. Carica papaya is a tropical plant that is traditionally used in the treatment of various ailments including inflammatory conditions. A literature search was conducted by using the keywords "papaya", "anti-inflammatory and inflammation" and "immunomodulation and immune" along with cross-referencing. Both in vitro and in vivo investigation studies were included. This is a review of all studies published since 2000 on the anti-inflammatory activity of papaya extracts and their effects on various immune-inflammatory mediators. Studies on the anti-inflammatory activities of recognized phytochemicals present in papaya are also included. Although in vitro and in vivo studies have shown that papaya extracts and papaya-associated phytochemicals possess anti-inflammatory and immunomodulatory properties, clinical studies are lacking.

    Taraxacum officinale has been widely used as a folkloric medicine for the treatment of diverse diseases. The dried plant was extracted with 70% ethanol to generate its ethanol extract (TEE). For some experiments, ethyl acetate (EA), n-butanol (BuOH) and aqueous (Aq) fractions were prepared in succession from TEE. TEE showed a scavenging activity in the 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay, a diminishing effect on intracellular reactive oxygen species (ROS) level, and an anti-angiogenic activity in the chicken chorioallantoic (CAM) assay. In the carrageenan-induced air pouch model, TEE inhibited production of exudate, and significantly diminished nitric oxide (NO) and leukocyte levels in the exudate. It also possessed an inhibitory effect on acetic acid-induced vascular permeability and caused a dose-dependent inhibition on acetic acid-induced abdominal writhing in mice. Suppressive effects of TEE on the production of NO and expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) in lipopolysaccharide (LPS)-stimulated macrophages were also assessed. Among the fractions, the n-butanol fraction (BuOH) was identified to be most effective in the CAM assay. Collectively, Taraxacum officinale contains anti-angiogenic, anti-inflammatory and anti-nociceptive activities through its inhibition of NO production and COX-2 expression and/or its antioxidative activity.

  7. Compensatory anti-inflammatory response syndrome.

    2009-01-01

    The concept of 'Compensatory anti-inflammatory response syndrome' (CARS) was proposed in 1997 by Roger Bone (1941-1997) to qualify the consequences of the counter-regulatory mechanisms initiated to limit the overzealous inflammatory process in patients with infectious (sepsis) or non-infectious systemic inflammatory response syndrome (SIRS). One major consequence of CARS is the modification of the immune status that could favour the enhanced susceptibility of intensive care patients to nosocomial infections. Indeed, most animal 'two-hit' models illustrate an enhanced sensitivity to infection after a first insult. However, this observation is highly dependent on the experimental procedure. Numerous functions of circulating leukocytes are altered in sepsis and SIRS patients, as well as in animal models of sepsis or SIRS. However, this is rather a reprogramming of circulating leukocytes, since there is not a global defect of the immune cells functions. Furthermore, within tissues, leukocytes are rather primed or activated than immunosuppressed. Thus, CARS may be considered as an adapted compartmentalized response with the aim to silence some acute proinflammatory genes, and to maintain the possible expression of certain genes involved in the anti-infectious process.

    Inflammatory bowel disease (IBD) constitutes a growing public health concern in western countries. Bacteria with anti-inflammatory properties are lacking in the dysbiosis accompanying IBD. Selected strains of probiotic bacteria with anti-inflammatory properties accordingly alleviate symptoms and enhance treatment of ulcerative colitis in clinical trials. Such properties are also found in selected strains of dairy starters such as Propionibacterium freudenreichii and Lactobacillus delbrueckii (Ld). We thus investigated the possibility to develop a fermented dairy product, combining both starter and probiotic abilities of both lactic acid and propionic acid bacteria, designed to extend remissions in IBD patients. We developed a single-strain Ld-fermented milk and a two-strain P. freudenreichii and Ld-fermented experimental pressed cheese using strains previously selected for their anti-inflammatory properties. Consumption of these experimental fermented dairy products protected mice against trinitrobenzenesulfonic acid induced colitis, alleviating severity of symptoms, modulating local and systemic inflammation, as well as colonic oxidative stress and epithelial cell damages. As a control, the corresponding sterile dairy matrix failed to afford such protection. This work reveals the probiotic potential of this bacterial mixture, in the context of fermented dairy products. It opens new perspectives for the reverse engineering development of anti-inflammatory fermented foods designed for target populations with IBD, and has provided evidences leading to an ongoing pilot clinical study in ulcerative colitis patients. © 2015 WILEY-VCH Verlag GmbH & Co.

    Non-steroidal anti-inflammatory drugs (NSAIDs) have been widely used for the modulation of the inflammatory response. However, a number of facts involving the occurrence of gastrointestinal lesions have limited the chronic use of NSAIDs. In order to diminish the occurrence of gastrointestinal damage caused by NSAIDs, the combination of NSAIDs with the H2 receptor blocker, cimetidine, has been evaluated. The anti-inflammatory and ulcerogenic effects of indomethacin and tenoxicam in association with or without cimetidine were determined at pre-clinical levels. It was observed that the group of animals treated with indomethacin and cimetidine, or tenoxicam and cimetidine (10 mg/kg, p.o.) demonstrated a significant reduction (P < 0.05, ANOVA followed by Tukey-Kramer multiple comparison test) of type-III gastric ulcers. Furthermore, indomethacin or tenoxicam (10 mg/kg, p.o.) in association with cimetidine increased the anti-inflammatory activity. The group, which received indomethacin and cimetidine presented the best performance in decreasing the inflammatory process (P < 0.05, ANOVA followed by Tukey-Kramer multiple comparison test).

    Objective To evaluate the anti-inflammatory property of the leaf exacts of Gendarussa vulgaris (G. vulgaris) Nees. Methods G. vulgaris Nees of the family Apocynaceae is a medium sized tree grown in semishade or no shade and is common in the Ernad and Nilambur taluks of Kerala.Various parts of this plant have been used in the treatment of ulcers, sores, inflammation, dyspepsia, healing of wounds, etc. The present study aimed at the evaluation of anti-inflammatory property of the aqueous and alcoholic extracts of the leaves by both in vitro and in vivo methods. In vitro method was estimated by human red blood cell membrane stabilisation (HRBC) method and in vivo method was estimated on the carrageenan induced paw oedima. Results Both the methods showed significant anti-inflammatory property of the different extracts tested. Conclusions The alcoholic extract at a concentration of 300 mg/mL showed potent activity on comparing with the standard drug diclofenac sodium. PMID:23569746

  11. Anti-inflammatory glucocorticoids: changing concepts.

    Science.gov (United States)

    Newton, Robert

    2014-02-05

    Despite being the most effective anti-inflammatory treatment for chronic inflammatory diseases, the mechanisms by which glucocorticoids (corticosteroids) effect repression of inflammatory gene expression remain incompletely understood. Direct interaction of the glucocorticoid receptor (NR3C1) with inflammatory transcription factors to repress transcriptional activity, i.e. transrepression, represents one mechanism of action. However, transcriptional activation, or transactivation, by NR3C1 also represents an important mechanism of glucocorticoid action. Glucocorticoids rapidly and profoundly increase expression of multiple genes, many with properties consistent with the repression of inflammatory gene expression. For example: the dual specificity phosphatase, DUSP1, reduces activation of mitogen-activated protein kinases; glucocorticoid-induced leucine zipper (TSC22D3) represses nuclear factor-κB (NF-κB) and activator protein 1 (AP-1) transcriptional responses; inhibitor of κBα (NFKBIA) inhibits NF-κB; tristraprolin (ZFP36) destabilises and translationally represses inflammatory mRNAs; CDKN1C, a cell cycle regulator, may attenuate JUN N-terminal kinase signalling; and regulator of G-protein signalling 2 (RGS2), by reducing signalling from Gαq-linked G protein-coupled receptors (GPCRs), is bronchoprotective. While glucocorticoid-dependent transrepression can co-exist with transactivation, transactivation may account for the greatest level and most potent repression of inflammatory genes. Equally, NR3C1 transactivation is enhanced by β2-adrenoceptor agonists and may explain the enhanced clinical efficacy of β2-adrenoceptor/glucocorticoid combination therapies in asthma and chronic obstructive pulmonary disease. Finally, NR3C1 transactivation is reduced by inflammatory stimuli, including respiratory syncytial virus and human rhinovirus. This provides an explanation for glucocorticoid resistance.

    Green tea has been shown to have beneficial effects against a variety of diseases such as cancer, obesity, diabetes, cardiovascular disease, and neurodegenerative diseases. Through cellular, animal, and human experiments, green tea and its major component, epigallocatechin-3-gallate (EGCG) have been demonstrated to have anti-inflammatory effects. Our previous findings have indicated that green tea and EGCG suppress the gene and/or protein expression of inflammatory cytokines and inflammation-related enzymes. Using bibliographic databases, particularly PubMed (provided by the http://www.ncbi.nlm.nih.gov/pubmed, US National Library of Medicine, National Institutes of Health, United States), we examined the potential usefulness of green tea/EGCG for the prevention and treatment of inflammatory diseases in human clinical and epidemiological studies. We also reviewed results from cellular and animal experiments and proposed action mechanisms. Most of the results from the human studies indicated the beneficial effects of green tea and tea catechins against inflammatory diseases. The cellular and animal studies also provided evidence for the favorable effects of green tea/EGCG. These results are compatible with our previous findings and can be largely explained by a mechanism wherein green tea/EGCG acts as an antioxidant to scavenge reactive oxygen species, leading to attenuation of nuclear factor-κB activity. Since green tea and EGCG have multiple targets and act in a pleiotropic manner, we may consider their usage to improve the quality of life in patients with inflammatory disease. Green tea and EGCG have beneficial health effects and no severe adverse effects; however, care should be taken to avoid overdosage, which may induce deleterious effects including hepatic injury.

    Elaise G. Pierri

    Full Text Available ABSTRACT The present study aimed to investigate the anti-inflammatory activity of ethanolic extract from Casearia sylvestris Sw., Salicaceae, leaves and to identify the compounds responsible for this activity. The ethanolic extract from C. sylvestris leaves was fractionated by solid phase extraction and the chemical composition of extract and fractions were assessed by chromatographic techniques. Casearin-like clerodane diterpenes were quantified in ethanolic extract (27.4%, w/w and in fraction 2 of solid phase extraction (50.6%, w/w. Carrageenan-induced paw edema and carrageenan-induced pleurisy assays (rats were used to evaluate anti-inflammatory activity of ethanolic extract, its fractions and clerodane diterpenes from C. sylvestris – caseargrewiin F and casearin B. The ethanolic extract was tested in the rat paw edema model and the doses tested (10 and 100 mg/kg had no effect. In the pleurisy model, the extract doses of 300 and 500 mg/kg showed inhibitory effect. The fraction 2 of solid phase extraction (10 mg/kg, caseargrewiin F and casearin B (0.5 mg/kg showed a significant reduction (p < 0.05 of the carrageenan-induced paw edema in rats compared to indomethacin. Gastric ulcers were not observed in animals treated with samples from C. sylvestris. In conclusion, the ethanolic extract from C. sylvestris, its enriched fraction of clerodane diterpenes, casearin B and caseargrewiin F exhibited anti-inflammatory activity on in vivo models in rats. Casearin-like clerodane diterpenes may be considered active chemical markers for C. sylvestris leaves. On the other hand, these diterpenes are promising compounds in the development of new drugs with anti-inflammatory action without gastric side effects.

    2010-09-01

    Anti-inflammatory properties of bioactive titanium metals prepared by anodic oxidation (AO-Ti) and alkali-heat (AH-Ti) treatments were studied by bacterial adhesion test and myeloperoxidase (MPO) activity assay methods. The bioactivities of the metals were also evaluated by apatite formation ability and osteoblasts culture experiments. Both metals could induce apatite formation and support osteoblasts proliferation. At the condition with normal incandescent light shine, both bioactive titanium metals had antibacterial adhesion properties compared with the titanium metal without treatment. The MPO activity assay proved that they both showed anti-inflammatory properties in vivo. The bioactive AO-Ti had better anti-inflammatory properties than the AH-Ti. It indicated that it is possible to optimize the anti-inflammatory properties of the bioactive titanium metals by different preparation methods. (c) 2010 Wiley Periodicals, Inc.

  4. Radiation as anti-inflammatory agent

    International Nuclear Information System (INIS)

    Nagaraju, S.

    2012-01-01

    Radiation is used for many disease treatments, recently works are being conducted on benefits of radiation for treating inflammatory diseases but clinical practices are limited. There are always risks involved with radiation. Risks could include, but are not limited to, potential late effects, even the induction of tumor formation as well as changes in normal tissues. Recently it has been reported in three randomized double blind studies using radiation for patients with painful degenerative joint diseases. All the three studies showed improvement in symptoms within months, suggesting the some with acute disease improve spontaneously. The treatment actually did not improve the architecture of the joint, yet it decreased painful symptoms. Pathologic evaluation weeks later showed disappearance of edema in the joint space with diminished inflammation and joint swelling. Thus it is postulated some therapeutic effects of radiotherapy for inflammatory diseases are due to the ability of radiation to inhibit cell proliferation. Sometimes inflammatory cells which affect the inflammatory joint space. This may have long-term consequences if it exists during critical periods. This may explain the effectiveness of radiotherapy in prevention of inflammatory disease. It is also noted that the effects of very low radiation doses of less than 500 rads on acute inflammation formations are most spectacular. Mitigation of pain, edema and erythema occurs so fast and after such low doses that it is inconceivable that cell death or inhibition of proliferation could play any role in this process. The optimal therapeutic effects of low dose irradiation occur in the very early stages of inflammation when vascular dilatation, edema formation and leukocyte invasion are beginning. There certainly can be adverse effects from radiation, yet it has to be noted that more than 1,60,000 people die annually of adverse effects of simple non-steroidal anti-inflammatory pills that are available in the

    Compounds that combine metal-based drugs with covalently linked targeted organic agents have been shown, in some instances, to exhibit superior anticancer properties compared to the individual counterparts. Within this framework, we prepared a series of organometallic ruthenium(II)- and osmium(II)-p-cymene complexes modified with the nonsteroidal anti-inflammatory drugs (NSAIDs) indomethacin and diclofenac. The NSAIDs are attached to the organometallic moieties via monodentate (pyridine/phosphine) or bidentate (bipyridine) ligands, affording piano-stool Ru(II) and Os(II) arene complexes of general formula [M(η(6)-p-cymene)Cl2(N)], where N is a pyridine-based ligand, {2-(2-(1-(4-chlorobenzoyl)-5-methoxy-2-methyl-1H-indol-3-yl)acetoxy)ethyl-3-(pyridin-3-yl)propanoate} or {2-(2-(2-((2,6-dichlorophenyl)amino)phenyl)acetoxy)ethyl-3-(pyridin-3-yl)propanoate}, [M(η(6)-p-cymene)Cl2(P)], where P is a phosphine ligand, {2-(2-(1-(4-chlorobenzoyl)-5-methoxy-2-methyl-1H-indol-3-yl)acetoxy)ethyl-4-(diphenylphosphanyl)benzoate} or {2-(2-(2-((2,6-dichlorophenyl)amino)phenyl)acetoxy)ethyl-4-(diphenylphosphanyl)benzoate, and [M(η(6)-p-cymene)Cl(N,N')][Cl], where N,N' is a bipyridine-based ligand, (4'-methyl-[2,2'-bipyridin]-4-yl)methyl-2-(1-(4-chlorobenzoyl)-5-methoxy-2-methyl-1H-indol-3-yl)acetate), (4'-methyl-[2,2'-bipyridin]-4-yl)methyl-2-(2-((2,6-dichlorophenyl)amino)phenyl)acetate), (bis(2-(2-(1-(4-chlorobenzoyl)-5-methoxy-2-methyl-1H-indol-3-yl)acetoxy)ethyl)[2,2'-bipyridine]-5,5'-dicarboxylate), or (bis(2-(2-(2-((2,6-dichlorophenyl)amino)phenyl)acetoxy)ethyl)[2,2'-bipyridine]-5,5'-dicarboxylate). The antiproliferative properties of the complexes were assessed in human ovarian cancer cells (A2780 and A2780cisR, the latter being resistant to cisplatin) and nontumorigenic human embryonic kidney (HEK-293) cells. Some of the complexes are considerably more cytotoxic than the original drugs and also display significant cancer cell selectivity.

    Our previous studies revealed that silver nanoparticles (AgNPs) promoted wound healing in part through their anti-inflammatory actions. As recent reports also suggested anti-inflammatory effects of dendrimers, we therefore undertook this study using dendrimer as the delivery system for AgNP to explore any potential synergistic anti-inflammatory efficacy. Lipopolysaccharide (LPS) was added to cultured RAW264.7 and J774.1 cells to mimic in vitro inflammation condition, followed by the addition of either silver dendrimer nanocomposite (Ag-DNC), AgNPs, or dendrimer. The levels of inflammatory markers TNF-alpha and interleukin-6 were assessed using ELISA assay. Furthermore, in vivo effects such of Ag-DNC, AgNPs, or dendrimer were studied in a burn wound model in mice. Our results confirmed that both naked dendrimer and AgNPs had anti-inflammatory properties. In in vitro study, Ag-DNC was shown to have the best anti-inflammatory efficacy than AgNPs or dendrimer alone. In-vivo experiments also indicated that animals in the Ag-DNC group had the fastest healing time with the least inflammation. Our study would suggest that dendrimer could provide additional anti-inflammatory benefits and might be an excellent delivery system for silver nanoparticles for future clinical application.

    Full Text Available In folklore systems of medicine, bilberry fruit and leaf extracts have been used for the treatment of diarrhoea, dysentery, diabetes, inflammation, and ulcer. The present study was to determine antioxidant, anti-inflammatory, and antiulcerogenic activities of Vaccinium leschenaultii Wight leaf and fruit. The phenolic, tannin, and flavonoid contents of V. leschenaultii leaf and fruit were quantified and were subjected to assess their antioxidant potential using various in vitro systems such as 1, 1 diphenyl-2-picrylhydrazyl, 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid radical scavenging, phosphomolybdenum, and ferric reducing antioxidant power reduction activities. Based on the antioxidant potential, acetone and methanol extracts of leaf and fruit were used to evaluate the anti-inflammatory activity and protective effect against ethanol-induced gastric damage in a rat model. The quantification of secondary metabolites shows that the phenolic, flavonoid, and tannin contents are higher in methanol extracts of fruit and leaf. The results of antioxidant assays exhibited that the methanol extracts of leaf possesses better 1, 1 diphenyl-2-picrylhydrazyl radical scavenging and ferric reducing power activity. Oral administration of the acetone fruit and leaf extracts of V. leschenaultii were capable of reducing the edema formation in rats against carrageenan and egg albumin induced inflammation. Moreover, leaf and fruit acetone extracts at the dose of 400 mg/kg highly inhibited ulcer formation. The study concluded that the plant substances such as total phenols, flavonoids along with appreciable antioxidant potential could be the supportive evidence to prove both the anti-inflammatory and antiulcer activities of V. leschenaultii. The traditional importance of this plant will help to reveal the potential of plant to provide alternative phytotherapeutics for human health.

    Full Text Available Angioedema is the end result of deep dermal, subcutaneous and/or mucosal swelling, and is potentially a life- threatening condition in cases where the pharynx or larynx is involved. Drug-induced angioedema has been reported to occur in response to a wide range of drugs and vaccines. Drug-induced angioedema, like other cutaneous drug reactions, has been reported to be most frequently elicited by beta-lactam antibiotics and nonsteroidal anti-inflammatory drugs, although reliable data from epidemiologic studies are scarce. Recent reports suggested an increasing role of angiotensin-converting enzyme inhibitors (ACEIs in the causation of life- threatening angioedema. ACEI-related angioedema is never accompanied by urticaria and occurs via a kinin- dependent mechanism. ACEI-related angioedema not only can start years after beginning the treatment, but it can then recur irregularly while under that treatment. Furthermore, allergy tests are unreliable for the diagnosis of ACEI-related angioedema, and so the relationship between angioedema and ACEIs is often missed and consequently quite underestimated. Accordingly, better understanding of the kinin-dependent mechanism, which is particular to angioedema, is necessary for the appropriate management of drug-induced angioedema.

    Full Text Available The New Zealand green lipped mussel preparation Lyprinol is available without a prescription from a supermarket, pharmacy or Web. The Food and Drug Administration have recently warned Lyprinol USA about their extravagant anti-inflammatory claims for Lyprinol appearing on the web. These claims are put to thorough review. Lyprinol does have anti-inflammatory mechanisms, and has anti-inflammatory effects in some animal models of inflammation. Lyprinol may have benefits in dogs with arthritis. There are design problems with the clinical trials of Lyprinol in humans as an anti-inflammatory agent in osteoarthritis and rheumatoid arthritis, making it difficult to give a definite answer to how effective Lyprinol is in these conditions, but any benefit is small. Lyprinol also has a small benefit in atopic allergy. As anti-inflammatory agents, there is little to choose between Lyprinol and fish oil. No adverse effects have been reported with Lyprinol. Thus, although it is difficult to conclude whether Lyprinol does much good, it can be concluded that Lyprinol probably does no major harm.

    Full Text Available Objective: The objective of the study is to evaluate the acute and chronic anti-inflammatory activities of root extract of Alpinia galanga in rodents. Materials and Methods: The study was carried out using albino rats of either sex (150-200 g. An extract of the root of A. galanga was prepared using absolute alcohol and distillation in a Soxhlet apparatus. The acute anti-inflammatory effects of this extract were evaluated using carrageenan-, bradykinin-, and 5-HT-induced rat paw edema. The chronic anti-inflammatory effects were evaluated using formaldehyde-induced rat paw edema. Results and Analysis: Inhibition of inflammation was seen to be 32.22% in carrageenan-induced, 37.70% in 5-HT-induced, and 35.21% in bradykinin-induced anti-inflammatory models. In chronic inflammatory model, a progressive inhibition of 34.73% (3 rd day, 37.50% (5 th day, 38.83% (7 th day, 44.66% (9 th day, 49.59% (11 th day, and 55.75% (13 th day was observed with study compound. The efficacy was comparable with the standard drugs. Conclusion: It can be thus concluded that A. galanga has anti-inflammatory properties and probably acts by blocking histaminic and serotonin pathways. It may be an effective alternative to NASAIDs and corticosteroid in inflammatory disorders.

    Full Text Available Abstract Acute and chronic tendon injuries are very common among athletes and in sedentary population. Most physicians prescribe anti-inflammatory managements to relieve the worst symptoms of swelling and pain, including non-steroidal anti-inflammatory drugs, corticosteroids and physical therapies. However, experimental research shows that pro-inflammatory mediators such as prostaglandins may play important regulatory roles in tendon healing. Noticeably nearly all cases of chronic tendon injuries we treat as specialists have received non-steroidal anti-inflammatory drugs by their physician, suggesting that there might be a potential interaction in some of these cases turning a mild inflammatory tendon injury into chronic tendinopathy in predisposed individuals. We are aware of the fact that non-steroidal anti-inflammatory drugs and corticosteroids may well have a positive effect on the pain control in the clinical situation whilst negatively affect the structural healing. It follows that a comprehensive evaluation of anti-inflammatory management for tendon injuries is needed and any such data would have profound clinical and health economic importance.

    Full Text Available Background & objectives: Antidepressants are being used as analgesics for various pain related disorders like neuropathic and non neuropathic pain. Although their analgesic activity is well recognized but anti-inflammatory potential of antidepressants is still inconclusive. Since the antidepressants are used for longer duration, it becomes important to elucidate effect of anti-depressants on blood pressure and gastric mucosa. This study was undertaken to evaluate the anti-inflammatory potential of various antidepressant drugs as well as their effect on blood pressure and gastric tolerability on chronic administration in rats. Methods: Rat paw oedema model was used for studying anti-inflammatory activity, single dose of test drug (venlafaxine 20 and 40 mg/kg, amitryptline 25 mg/kg, fluoxetine 20 mg/kg was administered intraperitoneally 45 min prior to administration of 0.1 ml of 1 per cent carrageenan in sub-planter region. Oedema induced in test group was compared with normal saline treated control group. For studying effect on blood pressure and gastric tolerability, test drugs were administered for 14 days. Blood pressure was recorded on days 0, 7 and 14 using tail cuff method. On day 14, 4 h after drug administration, rats were sacrificed and stomach mucosa was examined for ulcerations. Results: Pretreatment of rats with venlafaxine (40 mg/kg resulted in a significant decrease in paw oedema as compared to control (2.4 ± 0.15 to 1.1 ± 0.16 ml, P<0.01. Similarly, in the group pretreated with fluoxetine, significant decrease in paw oedema was observed in comparison to control (P<0.05. Significant change in mean blood pressure was seen in rats pretreated with venlafaxine 40 mg/kg (126.7 ± 4.2 to 155.2 ± 9.7, P<0.05 and fluoxetine (143.5 ± 2.6 to 158.3 ± 1.2, P<0.05 on day 7. No significant difference with regard to gastric tolerability was observed among groups. Interpretation & conclusions: Our findings showed significant anti-inflammatory

    Non-steroidal anti-inflammatory drugs (NSAIDs) are among the most commonly used drugs in the world. While the role of NSAIDs as cyclooxygenase (COX) inhibitors is well established, other targets may contribute to anti-inflammation. Here we report caspases as a new pharmacological target for NSAID family drugs such as ibuprofen, naproxen, and ketorolac at physiologic concentrations both in vitro and in vivo. We characterize caspase activity in both in vitro and in cell culture, and combine computational modeling and biophysical analysis to determine the mechanism of action. We observe that inhibition of caspase catalysis reduces cell death and the generation of pro-inflammatory cytokines. Further, NSAID inhibition of caspases is COX independent, representing a new anti-inflammatory mechanism. This finding expands upon existing NSAID anti-inflammatory behaviors, with implications for patient safety and next-generation drug design. Copyright © 2017 Elsevier Ltd. All rights reserved.

    In this study, we evaluated the anti-inflammatory activity of the soluble ethyl acetate fraction and chemical components of the stem bark of Passiflora foetida (Passifloraceae). Ten flavonoids (1-10) were isolated by various chromatographic techniques, and their structures were determined based on spectroscopic analyses by using nuclear magnetic resonance (NMR). Luteolin (2) and chrysoeriol (3) showed the most potent inhibition of nitric oxide (NO) production in macrophage cell line, RAW264.7, with half maximal inhibitor concentration (IC50) values of 1.2 and 3.1 μM, respectively. These compounds suppressed lipopolysaccharide (LPS)-induced inducible NO synthase (iNOS) expression at the transcription level. Our research indicates that the stem bark of P. foetida has significant anti-inflammatory properties, suggesting that its flavonoids may have anti-inflammatory benefits.

    This report describes the isolation and characterization of kalanchosine dimalate (KMC), an anti-inflammatory salt from the fresh juice of the aerial parts of Kalanchoe brasiliensis. KMC comprises the new metabolite kalanchosine (1) and malic acid (2) in a 1:2 stoichiometric ratio. Kalanchosine (1), 3,6-diamino-4,5-dihydroxyoctanedioic acid, is the first naturally occurring dimeric bis(gamma-hydroxy-beta-amino acid) and is at least partially responsible for the anti-inflammatory properties of K. brasiliensis.

  18. Anti-inflammatory Effects of Fungal Metabolites in Mouse Intestine as Revealed by In vitro Models

    Full Text Available Inflammatory bowel diseases (IBD, which include Crohn's disease and ulcerative colitis, are chronic inflammatory disorders that can affect the whole gastrointestinal tract or the colonic mucosal layer. Current therapies aiming to suppress the exaggerated immune response in IBD largely rely on compounds with non-satisfying effects or side-effects. Therefore, new therapeutical options are needed. In the present study, we investigated the anti-inflammatory effects of the fungal metabolites, galiellalactone, and dehydrocurvularin in both an in vitro intestinal inflammation model, as well as in isolated myenteric plexus and enterocyte cells. Administration of a pro-inflammatory cytokine mix through the mesenteric artery of intestinal segments caused an up-regulation of inflammatory marker genes. Treatment of the murine intestinal segments with galiellalactone or dehydrocurvularin by application through the mesenteric artery significantly prevented the expression of pro-inflammatory marker genes on the mRNA and the protein level. Comparable to the results in the perfused intestine model, treatment of primary enteric nervous system (ENS cells from the murine intestine with the fungal compounds reduced expression of cytokines such as IL-6, TNF-α, IL-1β, and inflammatory enzymes such as COX-2 and iNOS on mRNA and protein levels. Similar anti-inflammatory effects of the fungal metabolites were observed in the human colorectal adenocarcinoma cell line DLD-1 after stimulation with IFN-γ (10 ng/ml, TNF-α (10 ng/ml, and IL-1β (5 ng/ml. Our results show that the mesenterially perfused intestine model provides a reliable tool for the screening of new therapeutics with limited amounts of test compounds. Furthermore, we could characterize the anti-inflammatory effects of two novel active compounds, galiellalactone, and dehydrocurvularin which are interesting candidates for studies with chronic animal models of IBD.

    AIM: To investigate the effect of aqueous extract from Mangifera indica L. (MIE) on dextran sulfate sodium (DSS)-induced colitis in rats. METHODS: MIE (150 mg/kg) was administered in two different protocols: (1) rectally, over 7 d at the same time as DSS administration; and (2) once daily over 14 d (by oral gavage, 7 d before starting DSS, and rectally for 7 d during DSS administration). General observations of clinical signs were performed. Anti-inflammatory activity of MIE was assessed by myeloperoxidase (MPO) activity. Colonic lipid peroxidation was determined by measuring the levels of thiobarbituric acid reactive substances (TBARS). Reduced glutathione (GSH) levels, expression of inflammatory related mediators [inducible isoforms of nitric oxide synthase (iNOS) and cyclooxygenase (COX)-2, respectively] and cytokines [tumor necrosis factor (TNF)-α and TNF receptors 1 and 2] in colonic tissue were also assessed. Interleukin (IL)-6 and TNF-α serum levels were also measured. RESULTS: The results demonstrated that MIE has anti-inflammatory properties by improvement of clinical signs, reduction of ulceration and reduced MPO activity when administered before DSS. In addition, administration of MIE for 14 d resulted in an increase in GSH and reduction of TBARS levels and iNOS, COX-2, TNF-α and TNF R-2 expression in colonic tissue, and a decrease in IL-6 and TNF-α serum levels. CONCLUSION: MIE has anti-inflammatory activity in a DSS-induced rat colitis model and preventive administration (prior to DSS) seems to be a more effective protocol. PMID:20954278

    The Japanese Society of Gastroenterology (JSGE) revised the evidence-based clinical practice guidelines for peptic ulcer disease in 2014 and has created an English version. The revised guidelines consist of seven items: bleeding gastric and duodenal ulcers, Helicobacter pylori (H. pylori) eradication therapy, non-eradication therapy, drug-induced ulcer, non-H. pylori, non-nonsteroidal anti-inflammatory drug (NSAID) ulcer, surgical treatment, and conservative therapy for perforation and stenosis. Ninety clinical questions (CQs) were developed, and a literature search was performed for the CQs using the Medline, Cochrane, and Igaku Chuo Zasshi databases between 1983 and June 2012. The guideline was developed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system. Therapy is initially provided for ulcer complications. Perforation or stenosis is treated with surgery or conservatively. Ulcer bleeding is first treated by endoscopic hemostasis. If it fails, surgery or interventional radiology is chosen. Second, medical therapy is provided. In cases of NSAID-related ulcers, use of NSAIDs is stopped, and anti-ulcer therapy is provided. If NSAID use must continue, the ulcer is treated with a proton pump inhibitor (PPI) or prostaglandin analog. In cases with no NSAID use, H. pylori-positive patients receive eradication and anti-ulcer therapy. If first-line eradication therapy fails, second-line therapy is given. In cases of non-H. pylori, non-NSAID ulcers or H. pylori-positive patients with no indication for eradication therapy, non-eradication therapy is provided. The first choice is PPI therapy, and the second choice is histamine 2-receptor antagonist therapy. After initial therapy, maintenance therapy is provided to prevent ulcer relapse.

    The incidence of acid-base disorders (ABDs) is high, especially in hospitalized patients. ABDs are often indicators for severe systemic disorders. In everyday clinical practice, analysis of ABDs must be performed in a standardized manner. Highly sensitive diagnostic tools to distinguish the various ABDs include the anion gap and the serum osmolar gap. Drug-induced ABDs can be classified into five different categories in terms of their pathophysiology: (1) metabolic acidosis caused by acid overload, which may occur through accumulation of acids by endogenous (e.g., lactic acidosis by biguanides, propofol-related syndrome) or exogenous (e.g., glycol-dependant drugs, such as diazepam or salicylates) mechanisms or by decreased renal acid excretion (e.g., distal renal tubular acidosis by amphotericin B, nonsteroidal anti-inflammatory drugs, vitamin D); (2) base loss: proximal renal tubular acidosis by drugs (e.g., ifosfamide, aminoglycosides, carbonic anhydrase inhibitors, antiretrovirals, oxaliplatin or cisplatin) in the context of Fanconi syndrome; (3) alkalosis resulting from acid and/or chloride loss by renal (e.g., diuretics, penicillins, aminoglycosides) or extrarenal (e.g., laxative drugs) mechanisms; (4) exogenous bicarbonate loads: milk-alkali syndrome, overshoot alkalosis after bicarbonate therapy or citrate administration; and (5) respiratory acidosis or alkalosis resulting from drug-induced depression of the respiratory center or neuromuscular impairment (e.g., anesthetics, sedatives) or hyperventilation (e.g., salicylates, epinephrine, nicotine).

    Heparin, a glycosaminoglycan (GAG), has both anti-inflammatory and anti-coagulant properties. The clinical use of heparin against inflammation, however, has been limited by concerns about increased bleeding. While the anti-coagulant activity of heparin is well understood, its anti-inflammatory properties are less so. Heparin is known to bind to certain cytokines, including chemokines, small proteins which mediate inflammation through their control of leukocyte migration and activation. Molecules which can interrupt the chemokine-GAG interaction without inhibiting coagulation could therefore, represent a new class of anti-inflammatory agents. In the present study, two approaches were undertaken, both focusing on the heparin-chemokine relationship. In the first, a structure based strategy was used: after an initial screening of potential small molecule binders using protein NMR on a target chemokine, binding molecules were optimized through structure-based design. In the second approach, commercially available short oligosaccharides were polysulfated. In vitro, these molecules prevented chemokine-GAG binding and chemokine receptor activation without disrupting coagulation. However, in vivo, these compounds caused variable results in a murine peritoneal recruitment assay, with a general increase of cell recruitment. In more disease specific models, such as antigen-induced arthritis and delayed-type hypersensitivity, an overall decrease in inflammation was noted, suggesting that the primary anti-inflammatory effect may also involve factors beyond the chemokine system.

    Medicinal mushrooms have been essential components of traditional Chinese herbal medicines for thousands of years, and they protect against diverse health-related conditions. The components responsible for their anti-inflammatory activity have yet to be fully studied. This study investigates the anti-inflammatory activity of n-hexane, chloroform, ethyl acetate, and methanol extracts of mycelia in submerged culture from 5 commercially available medicinal mushrooms, namely Cephalosporium sinensis, Cordyceps mortierella, Hericium erinaceus, Ganoderma lucidum, and Armillaria mellea. MTT colorimetric assay was applied to measure the cytotoxic effects of different extracts. Their anti-inflammatory activities were evaluated via inhibition against production of lipopolysaccharide (LPS)-induced nitric oxide (NO) in murine macrophage-like cell line RAW264.7 cells. Of the 20 extracts, n-hexane, chloroform, ethyl acetate, and methanol extracts from C. sinensis, C. mortierella, and G. lucidum; chloroform extracts from H. erinaceus and A. mellea; and ethyl acetate extracts from A. mellea at nontoxic concentrations (effective inhibitor, with the lowest half maximal inhibitory concentration (64.09 ± 6.29 μg/mL) of the LPS-induced NO production. These results indicate that extracts from medicinal mushrooms exhibited anti-inflammatory activity that might be attributable to the inhibition of NO generation and can therefore be considered a useful therapeutic and preventive approach to various inflammation-related diseases.

    2015-01-01

    The inflammatory response is a highly regulated process, and its dysregulation can lead to the establishment of chronic inflammation and, in some cases, to death. Inflammation is the cause of several diseases, including rheumatoid arthritis, inflammatory bowel diseases, multiple sclerosis, and asthma. The search for agents inhibiting inflammation is a great challenge as the inflammatory response plays an important role in the defense of the host to infections. Marine invertebrates are exceptional sources of new natural products, and among those diterpenoids secondary metabolites exhibit notable anti-inflammatory properties. Novel anti-inflammatory diterpenoids, exclusively produced by marine organisms, have been identified and synthetic molecules based on those structures have been obtained. The anti-inflammatory activity of marine diterpenoids has been attributed to the inhibition of Nuclear Factor-κB activation and to the modulation of arachidonic acid metabolism. However, more research is necessary to describe the mechanisms of action of these secondary metabolites. This review is a compilation of marine diterpenoids, mainly isolated from corals, which have been described as potential anti-inflammatory molecules. PMID:26538822

    Full Text Available Smallanthus sonchifolius (Poepp. H. Rob. , Asteraceae, known as yacon, is an herb that is traditionally used for the treatment of diabetes in folk medicine. However, recent studies have demonstrated that this plant has other interesting properties such as anti-microbial and anti-inflammatory actions. Thus, the purpose of this study was to evaluate the topical anti-inflammatory property of different extracts prepared from yacon leaves and analyze the role of different chemical classes in this activity. Three yacon leaf extracts were obtained: aqueous extract, where chlorogenic acid derivatives and sesquiterpene lactones were detected; leaf rinse extract, rich in sesquiterpene lactones; and polar extract, rich in chlorogenic acid derivatives. All the extracts exhibited anti-edematogenic activity in vivo (aqueous extract: 25.9% edema inhibition at 0.50 mg/ear; polar extract: 42.7% inhibition at 0.25 mg/ear; and leaf rinse extract: 44.1% inhibition at 0.25 mg/ear. The leaf rinse extract furnished the best results regarding neutrophil migration inhibition, and NO, TNF-α and PGE2 inhibition. These data indicate that both sesquiterpene lactones and chlorogenic acid derivatives contribute to the anti-inflammatory action, although sesquiterpene lactones seem to have more pronounced effects. In conclusion, yacon leaf extracts, particularly the sesquiterpene lactone-rich extract, has potential use as topical anti-inflammatory agent.

The starting compounds 6-amino-7-cyano-N-(4-(un)substitutedphenyl)-2,3-dihydro-1H-pyrrolizine-5-carboxamides 9a-c were reacted with different aldehydes, acid chlorides, and acid anhydrides to give the target compounds. The structures of the new compounds were characterized by spectral and elemental analyses. All compounds were tested for their anti-inflammatory activity using the carrageenan-induced rat paw oedema model and exhibited weak to good activities compared to ketorolac as the reference drug. Also, analgesic activity of selected compounds, which are the most active in the anti-inflammatory screening, was measured using the acetic acid-induced writhing model; revealing activities comparable to or higher than ketorolac. Ulcer indices for the most active compounds were calculated and some compounds showed no or minimal ulcerogenic effect compared to ketorolac. Copyright 2009 Elsevier Masson SAS. All rights reserved.

    The roots of Ulmus macrocarpa Hance (Ulmaceae) have been used as an oriental traditional medicine for the treatment of inflammation, ulcers, cancers, and parasites. Activity guided isolation from the roots of U. macrocarpa yielded three flavonoids [catechin 7-O-β-D-apiofuranoside (1), (+)-catechin (2), taxifolin 6-C-glucopyranoside (3)], and one coumarin [fraxin (4)]. To investigate the antioxidative and anti-inflammatory effects of these compounds, DPPH radical scavenging activity and inhibitory activity against nitric oxide (NO) production in LPS-stimulated RAW 264.7 cells were examined and the expression of inducible NO synthase (iNOS) and cyclooxidase-2 (COX-2) were measured by RT-PCR and Western Blotting in HaCaT cells. Compounds 1, 2, and 3 showed moderate antioxidative activities compared with L-ascorbic acid as a positive control. NO production was reduced and the expressions of iNOS and COX-2 and their mRNA were inhibited by the addition of samples (1-4). These results suggest that the phenolic compounds from the roots of U. macrocarpa might be developed as antioxidant and anti-inflammatory agents.

It is endemic to Southern China and India, and widely naturalized in Malaysia, Western and Eastern Africa as well as in most islands of both the Pacific and Caribbean regions. This plant has been used in traditional medicine for the treatment of asthma, boil, diarrhoea, gout, inflammations, rheumatism, tumour and ulcers, and as a tonic. The dried and ground bark of A. pavonina L. was extracted, successively, with petroleum ether (PE, dichloromethane (DCM, ethyl acetate (EtOAc and methanol (MeOH, and the resulting extracts were assessed in vivo for anti-inflammatory activity on carrageenan-induced rat hind paw oedema as a model of inflammation. The extracts were administered orally at the doses of 200 and 400 mg/kg body weight, and statistically significant (p<0.001 anti-inflammatory effects were observed in a dose dependant manner. The MeOH extract (400 mg/kg showed 37.10% (p<0.01 inhibition of inflammation at the first hour of the study and, the DCM extract (400 mg/kg exhibited 33.11% (p<0.001 inhibition of inflammation at the third hour of the study which was comparable with that of reference standard drug dichlofenac sodium. The results of this study supported some of the traditional medicinal uses of this plant.

    Cutaneous leishmaniasis (CL) is caused by different species of the genus Leishmania. Pro- and anti-inflammatory cytokines play different roles in resistance/susceptibility and the immunopathogenesis of Leishmania infection. The balance and dynamic changes in cytokines may control or predict clinical outcome. T helper 1 (Th1) inflammatory cytokines (especially interferon-γ, tumor necrosis factor-α and interleukin-12) are the crucial factors in the initiation of protective immunity against L. major infection, whereas T helper 2 cytokines including IL-5, IL-4, and IL-13 facilitate the persistence of parasites by downregulating the Th1 immune response. On the other hand, aggravation of inflammatory reactions leads to collateral tissue damage and formation of ulcer. For this reason, immunity system such as T regulatory cells produce regulatory cytokines such as transforming growth factor-β and IL-10 to inhibit possible injures caused by increased inflammatory responses in infection site. In this article, we review the role of pro- and anti-inflammatory cytokines in the immunoprotection and immunopathology of CL. PMID:27660895

    Baccharis dracunculifolia DC (Asteraceae) is a Brazilian medicinal plant popularly used for its antiulcer and anti-inflammatory properties. This plant is the main botanical source of Brazilian green propolis, a natural product incorporated into food and beverages to improve health. The present study aimed to investigate the chemical profile and intestinal anti-inflammatory activity of B. dracunculifolia extract on experimental ulcerative colitis induced by trinitrobenzenosulfonic acid (TNBS). Colonic damage was evaluated macroscopically and biochemically through its evaluation of glutathione content and its myeloperoxidase (MPO) and alkaline phosphatase activities. Additional in vitro experiments were performed in order to test the antioxidant activity by inhibition of induced lipid peroxidation in the rat brain membrane. Phytochemical analysis was performed by HPLC using authentic standards. The administration of plant extract (5 and 50 mg kg−1) significantly attenuated the colonic damage induced by TNBS as evidenced both macroscopically and biochemically. This beneficial effect can be associated with an improvement in the colonic oxidative status, since plant extract prevented glutathione depletion, inhibited lipid peroxidation and reduced MPO activity. Caffeic acid, p-coumaric acid, aromadendrin-4-O-methyl ether, 3-prenyl-p-coumaric acid, 3,5-diprenyl-p-coumaric acid and baccharin were detected in the plant extract. PMID:19592480

    Inflammation often plays a key role in the perpetuation of pain. Chronic inflammatory conditions (e.g. osteoarthritis, immune system dysfunction, micro-circulatory disease, painful neuritis, and even heart disease) have increased as baby boomers age. Medicine's current anti-inflammatory choices are NSAIDs and steroids; the value in promoting cure and side effect risks of these medications are unclear and controversial, especially considering individual patient variations. Electricity has continuously been a powerful tool in medicine for thousands of years. All medical professionals are, to some degree, aware of electrotherapy; those who directly use electricity for treatment know of its anti-inflammatory effects. Electronic signal treatment (EST), as an extension of presently available technology, may reasonably have even more anti-inflammatory effects. EST is a digitally produced alternating current sinusoidal electronic signal with associated harmonics to produce theoretically reasonable and/or scientifically documented physiological effects when applied to the human body. These signals are produced by advanced electronics not possible even 10 to 15 years ago. The potential long-lasting anti-inflammatory effects of some electrical currents are based on basic physical and biochemical facts listed in the text below, namely that of stimulating and signaling effective and long-lasting anti-inflammatory effects in nerve and muscle cells. The safety of electrotherapeutic treatments in general and EST in particular has been established through extensive clinical use. The principles of physics have been largely de-emphasized in modern medicine in favor of chemistry. These electrical treatments, a familiar application of physics, thus represent powerful and appropriate elements of physicians' pain care armamentaria in the clinic and possibly for prescription for use at home to improve overall patient care and maintenance of quality of life via low-risk and potentially

    Methanolic extracts of six plants (Arbutus andrachne, Chrysanthemum coronarium, Inula viscosa, Origanum syriacum, Punica granatum, and Rosmarinus officinalis) used in traditional medicine for the treatment of bacterial and fungal infections were evaluated. The present study was conducted to evaluate the antimicrobial and anti-inflammatory activity of some medicinal plants in lowering the risk of opportunistic infections of the oral cavity caused by Staphylococcus aureus, Pseudomonas aeruginosa, and Candida albicans. Extracts were evaluated separately and in a mixture. The methanolic plant extracts were tested against three opportunistic microorganisms by determining the minimum inhibitory concentration (MIC). They were also evaluated for their ability to suppress the release of the pro-inflammatory cytokine IL-6 while not suppressing the release of the anti-inflammatory cytokine IL-10 from peripheral blood mononuclear cells using ELISA. All extracts showed both antimicrobial and anti-inflammatory activities. However, O. syriacum exhibited the highest antimicrobial activity for the three microorganisms among all of the tested extracts (MIC S. aureus: 1 mg/mL; P. aeruginosa: 2 mg/mL; and C. albicans: 1 mg/mL). The extracts inhibited the expression of the pro-inflammatory cytokine IL-6 with apparent dose-dependent responses while they attenuated the secretion of the anti-inflammatory cytokine IL-10. The mixture of O. syriacum and R. officinalis showed an anti-inflammatory effect, with a synergistic antimicrobial effect. These findings support the idea that a diet rich in plants and herbs may contribute to the reduction of inflammation and microbial growth and may also be preventive against various infections, including those related to the oral cavity.

    Zea mays L. (Z. mays) has been used for human consumption in the various forms of meal, cooking oil, thickener in sauces and puddings, sweetener in processed food and beverage products, bio-disel. However, especially, in case of husk extract of Z. mays, little is known about its anti-inflammatory effects. Therefore, in this study, the anti-inflammatory effects of Z. mays husk extract (ZMHE) and its mechanisms of action were investigated. The husks of Z. Mays were harvested in kangwondo, Korea. To assess the anti-inflammatory activities of ZMHE, we examined effects of ZMHE on nitric oxide (NO) production, and release of soluble intercellular adhesion molecule-1 (sICAM-1) and eotaxin-1. The expression level of inducible nitric oxide synthase (iNOS) gene was also determined by Western blot and luciferase reporter assays. To determine its mechanisms of action, a luciferase reporter assay for nuclear factor kappa B (NF-kB) and activator protein-1 (AP-1) was introduced. ZMHE inhibited lipopolysaccharide (LPS)-induced production of NO in RAW264.7 cells. In addition, expression of iNOS gene was reduced, as confirmed by Western blot and luciferase reporter assays. Effects of ZMHE on the AP-1 and NF-kB promoters were examined to elucidate the mechanism of its anti-inflammatory activity. Activation of AP-1 and NF-kB promoters induced by LPS was significantly reduced by ZMHE treatment. In addition, LPS-induced production of sICAM-1 and IL-4-induced production of eotaxin-1 were all reduced by ZMHE. Our results indicate that ZMHE has anti-inflammatory effects by downregulating the expression of iNOS gene and its downregulation is mediated by inhibiting NF-kB and AP-1 signaling.

    Susceptibility to Helicobacter pylori infection is a poorly understood phenomenon. This study was undertaken to establish whether either smoking or chronic non-steroidal anti-inflammatory drug (NSAID) consumption might in some way predispose to H. pylori infection and hence lead to peptic ulceration. Serological evidence of H. pylori infection was assessed in 100 consecutive subjects receiving NSAIDs without any evidence of gastrointestinal upset and 100 matched controls. All subjects had a full assessment of their smoking habits. Sixty-three per cent of patients taking NSAIDs compared to 51% of controls had evidence of H. pylori infection (NS). Smoking habit also had no effect on H. pylori colonization. The ulcerogenic potential of NSAIDs and smoking does not appear to be mediated via a prediposition to H. pylori infection.

    Ulcerative colitis (UC) is a chronic inflammatory bowel disease (IBD) driven through altered immune responses with production of proinflammatory cytokines. Many therapies are used, but side effects and loss of response limit long-term effectiveness. New therapeutic strategies are thus needed for patients who don't respond to current treatments. Recently, there is suggested involvement of the proinflammatory hormone angiotensin II in inflammatory bowel disease. The aim of this study was to investigate the possible role of olmesartan medoxomil (OLM-M), an angiotensin II receptor blocker in ameliorating ulcerative colitis. Colitis was induced in male Wistar rats by administration of 5% dextran sodium sulphate (DSS) in drinking water for 5 days. OLM-M (1, 3 and 10 mg/kg) was administered orally during 21 days prior to the induction of colitis, and for 5 days after. Sulfasalazine (500 mg/kg) was used as reference drug. All animals were tested for changes in colon length, disease activity index (DAI) and microscopic damage. Colon tissue concentration/activity of tumor necrosis alpha (TNF-α), myeloperoxidase (MPO), prostaglandin E2 (PGE2), reduced glutathione (GSH) and malondialdehyde (MDA) were assessed. Results showed that the OLM-M dose-dependently ameliorated the colonic histopathological and biochemical injuries, an effect that is comparable or even better than that of the standard sulfasalazine. These results suggest that olmesartan medoxomil may be effective in the treatment of UC through its anti-inflammatory and antioxidant effects. - Highlights: • Olmesartan medoximil reduced dextran sodium sulphate- induced colitis. • Mechanism involved anti-inflammatory and antioxidant effects dose- dependently. • It suppressed malondialdehyde and restored reduced glutathione levels. • It reduced inflammatory markers levels and histological changes.

    The plant species Bursera copallifera (DC) bullock is used in traditional medicine to treat inflammation. The leaves of this plant can be prepared as an infusion to treat migraines, bronchitis, and dental pain. The purpose of this study was to determine the anti-inflammatory and cytotoxic activities of organic extracts from the stems, stem bark, and leaves of B. copallifera, which was selected based on the knowledge of its traditional use. We evaluated the ability of extracts to inhibit mouse ear inflammation in response to topical application of 12-O tetradecanoylphorbol-13-acetate. The extracts with anti-inflammatory activity were evaluated for their inhibition of pro-inflammatory enzymes. In addition, the in vitro cytotoxic activities of the organic extracts were evaluated using the sulforhodamine B assay. The hydroalcoholic extract of the stems (HAS) exhibited an anti-inflammatory activity of 54.3% (0.5 mg/ear), whereas the anti-inflammatory activity of the dichloromethane-methanol extract from the leaves (DMeL) was 55.4% at a dose of 0.1 mg/ear. Methanol extract from the leaves (MeL) showed the highest anti-inflammatory activity (IC50 = 4.4 μg/mL), hydroalcoholic extract of leaves, and DMeL also reduce the enzyme activity, (IC50 = 6.5 μg/mL, IC50 = 5.7 μg/mL), respectively, from stems HAS exhibit activity at the evaluated concentrations (IC50 =6.4 μg/mL). The hydroalcoholic extract of the stems exhibited the highest cytotoxic activity against a breast adenocarcinoma cell line (MCF7, IC50 = 0.90 μg/mL), whereas DMeL exhibited an IC50 value of 19.9 μg/mL. In conclusion, extracts from leaves and stems inhibited cyclooxygenase-1, which is the target enzyme for nonsteroidal anti inflammatory drugs, and some of these extracts demonstrated substantial antiproliferative effects against the MCF7 cell line. These results validate the traditional use of B. copallifera.

    Full Text Available Nonsteroidal anti-inflammatory drug (NSAID could induce gastrointestinal (GI injury by way of topical (mucus, gastric acid and drug interaction and systemic mechanism (decreased prostaglandin synthesis. Compared with non-NSAID users, elderly taking NSAID or aspirin have a higher chance than younger people of developing GI bleeding (5.5-fold vs. 1.65-fold. Endoscopy is the best tool to identify the source and severity of ulcer with bleeding. The use of NSAID or aspirin should be weighed carefully in elderly who have a history of peptic ulcer. If necessary, it is better to choose cyclooxygenase-2 inhibitor since it has been reported that the drug has less than half the risk of non-selective NSAID to ignite GI complications. Eradication of Helicobacter pylori might reduce ulcer risk in new NSAID users, but not in patients with long-term therapy. Proton pump inhibitor is the drug of choice that is effective for both treatment and prevention (taken together with NSAID of NSAID-related GI bleeding.

    Cinnamic acids have been identified as interesting compounds with cytotoxic, anti-inflammatory, and antioxidant properties. Lipoxygenase pathway, catalyzing the first two steps of the transformation of arachidonic acid into leukotrienes is implicated in several processes such as cell differentiation, inflammation and carcinogenesis. Development of drugs that interfere with the formation or effects of these metabolites would be important for the treatment of various diseases like asthma, psoriasis, ulcerative colitis, rheumatoid arthritis, atherosclerosis, cancer, and blood vessel disorders. Till now, asthma consists of the only pathological case in which improvement has been shown by lipoxygenase LO inhibitors. Thus, the research has been directed towards the development of drugs that interfere with the formation of leukotrienes. In order to explore the anti-inflammatory and cytotoxic effects of antioxidant acrylic/cinnamic acids a series of derivatives bearing the appropriate moieties have been synthesized via the Knoevenagel condensation and evaluated for their biological activities. The compounds have shown important antioxidant activity, anti-inflammatory activity and very good inhibition of soybean lipoxygenase while some of them were tested for their anticancer activity.

    Punica granatum (pomegranate), an edible fruit originating in the Middle East, has been used as a traditional medicine for treatment of pain and inflammatory conditions such as peptic ulcer. The numerous risks associated with nonsteroidal anti-inflammatory drugs (NSAIDs) for treatment of pain and inflammation give rise to using medicinal herbs as alternative therapies. This study aimed to evaluate the anti-inflammatory effect of isolated compounds from the ethyl acetate (EtOAc) fraction of P. granatum by determination of their inhibitory effects on lipopolysaccharide (LPS), stimulated nitric oxide (NO), prostaglandin E2 (PGE-2), interleukin-6 (IL-6) and cyclooxxgenase-2 (COX-2) release from RAW264.7 cells. The compounds ellagic acid, gallic acid and punicalagin A&B were isolated from EtOAc by high performance liquid chromatography (HPLC) and further identified by mass spectrometry (MS). The inhibitory effect of ellagic acid, gallic acid and punicalagin A&B were evaluated on the production of LPS-induced NO by Griess reagent, PGE-2 and IL-6 by immunoassay kit and prostaglandin E2 competitive ELISA kit, and COX-2 by Western blotting. Ellagic acid, gallic acid and punicalagin A&B potentially inhibited LPS-induced NO, PGE-2 and IL-6 production. The results indicate that ellagic acid, gallic acid and punicalagin may be the compounds responsible for the anti-inflammatory potential of P. granatum.

    examination of the stomach revealed normal mucosa for both tested compounds and controls. Likewise, kidneys showed neither significant histologic alteration nor biomarkers increase as compared to the control over both 7- and 30-day treatment periods. Mice that received the tested compounds or diclofenac exhibited transient liver damage specifically; congestion, vacuolization, necrosis and inflammation after 7 days of treatment which decreased significantly after 30 days of treatment as emphasized by the Suzuki score and biomarker levels. Conclusion: Since the tested compounds, specifically compound I, presented a satisfactory chronic safety profile as well as anti-inflammatory effect, it is worth conducting further molecular pharmacological, toxicological and bioavailability studies to elucidate the efficacy of these potential anti-inflammatory bipyrazole compounds. Keywords: peptic ulcer, hepatic injury, kidney injury, nonsteroidal anti-inflammatory drugs, pyrazole, histology

    Mushrooms have been used extensively, owing to their nutritional and medicinal value, for thousands of years. Modern research confirms the therapeutic effect of traditionally used species. Inflammation is a natural response of the immune system to damaging factors, e.g. physical, chemical and pathogenic. Deficiencies of antioxidants, vitamins, and microelements, as well as physiological processes, such as aging, can affect the body's ability to resolve inflammation. Mushrooms are rich in anti-inflammatory components, such as polysaccharides, phenolic and indolic compounds, mycosteroids, fatty acids, carotenoids, vitamins, and biometals. Metabolites from mushrooms of the Basidiomycota taxon possess antioxidant, anticancer, and most significantly, anti-inflammatory properties. Recent reports indicate that edible mushroom extracts exhibit favourable therapeutic and health-promoting benefits, particularly in relation to diseases associated with inflammation. In all certainty, edible mushrooms can be referred to as a "superfood" and are recommended as a valuable constituent of the daily diet. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Full Text Available Inflammation, a biological response of body tissues to harmful stimuli, is also known to be involved in a host of diseases, such as obesity, atherosclerosis, rheumatoid arthritis, and even cancer. Isoflavones are a class of flavonoids that exhibit antioxidant, anticancer, antimicrobial, and anti-inflammatory properties. Increasing evidence has highlighted the potential for isoflavones to prevent the chronic diseases in which inflammation plays a key role, though the underlying mechanisms remain unclear. Recently, some studies have raised concerns about isoflavones induced negative effects like carcinogenesis, thymic involution, and immunosuppression. Therefore, this review aims to summarize the anti-inflammatory effects of isoflavones, unravel the underlying mechanisms, and present the potential health risks.

    Full Text Available Prostatic diseases are characterized by increased activity of cytokines, growth factors, and cyclooxygenases- (COX- 1 and 2. Activation of COX-1 and COX-2 results in increased levels of prostaglandins and the induction of angiogenic, antiapoptotic and inflammatory processes. Inhibition of COX enzymes by members of the widely used nonsteroidal anti-inflammatory drug (NSAID class of drugs decreases prostaglandin production, and exerts a variety of anti-inflammatory, antipyretic, and antinociceptive effects. While numerous in vitro, in vivo, and clinical studies have shown that NSAIDs inhibit the risk and progression of prostatic diseases, the relationship between NSAIDs and such diseases remains controversial. Here we review the literature in this area, critically analyzing the benefits and caveats associated with the use of NSAIDs in the treatment of prostatic diseases.

    2011-01-01

    Full Text Available Ouabain, an inhibitor of the Na+/K+-ATPase pump, was identified as an endogenous substance of human plasma. Ouabain has been studied for its ability to interfere with various regulatory mechanisms. Despite the studies portraying the ability of ouabain to modulate the immune response, little is known about the effect of this substance on the inflammatory process. The aim of this work was to study the effects triggered by ouabain on inflammation and nociceptive models. Ouabain produced a reduction in the mouse paw edema induced by carrageenan, compound 48/80 and zymosan. This anti-inflammatory potential might be related to the inhibition of prostaglandin E2, bradykinin, and mast-cell degranulation but not to histamine. Ouabain also modulated the inflammation induced by concanavalin A by inhibiting cell migration. Besides that, ouabain presented antinociceptive activity. Taken these data together, this work demonstrated, for the first time, that ouabain presented in vivo analgesic and anti-inflammatory effects.

    Colorectal cancer (CRC) is the third most common malignant neoplasm worldwide. Although conclusive evidence is still lacking, epidemiologic studies suggest that long-term use of non-steroidal anti-inflammatory drugs (NSAIDs) has chemopreventive properties against CRC. Similarly, regular consumption of mesalazine, a drug structurally related to NSAIDs, seems to reduce the risk of CRC in patients with ulcerative colitis. These observations are supported by a large body of experimental data showing the ability of such drugs to inhibit multiple pathways that sustain colon carcinogenesis. This review summarizes the current information on the molecular mechanisms by which NSAIDs and mesalazine could interfere with CRC cell growth and survival.

    Various clinical and epidemiologic studies show that nonsteroidal anti-inflammatory drugs (NSAIDs), including aspirin and cyclooxygenase inhibitors (COXIBs) help prevent cancer. Since eicosanoid metabolism is the main inhibitory targets of these drugs the resulting molecular and biological impact is generally accepted. As our knowledge base and technology progress we are learning that additional targets may be involved. This review attempts to summarize these new developments in the field.

    Essential oils are plant secondary metabolites with positive pharmacological properties, e.g. anti-oxidative, antimicrobial or immunomodulative, but they can have toxic and allergic effects as well. The aim of this study was to analyze anti-inflammatory effects of chamomile essential oil dietary administration in carrageenan paw oedema and trinitrobenzene sulfonic acid (TNBS) colitis. Mice received chamomile essential oil in three concentrations (5000, 2500 and 1250 ppm) in the standard roden...

    The aim of this study was to investigate anti-inflammatory and hepatoprotective activities of Plantago major L. (PM). Anti-inflammatory activity: Control and reference groups were administered isotonic saline solution (ISS) and indomethacin, respectively. Plantago major groups were injected PM in doses of 5 mg/kg (PM-I), 10 mg/kg (PM-II), 20 mg/kg (PM-III) and 25 mg/kg (PM-IV). Before and three hours after the injections, the volume of right hind-paw of rats was measured using a plethysmometer. HEPATOPROTECTIVE ACTIVITY: The hepatotoxicity was induced by carbon tetrachloride (CCl4) administration. Control, CCl4 and reference groups received isotonic saline solution, CCl4 and silibinin, respectively. Plantago major groups received CCl4 (0.8 ml/kg) and PM in doses of 10, 20 and 25 mg/kg, respectively for seven days. Blood samples and liver were collected on the 8th day after the animals were killed. Plantago major had an anti-inflammatory effect matching to that of control group at doses of 20 and 25 mg/kg. It was found that reduction in the inflammation was 90.01% with indomethacin, 3.10% with PM-I, 41.56% with PM-II, 45.87% with PM-III and 49.76% with PM-IV. Median effective dose (ED50) value of PM was found to be 7.507 mg/kg. Plantago major (25 mg/kg) significantly reduced the serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels when compared to the CCl4 group. The histopathological findings showed a significant difference between the PM (25 mg/kg) and CCl4 groups. The results showed that PM had a considerable anti-inflammatory and hepatoprotective activities.

    Full Text Available Accumulating epidemiological and clinical evidence shows that inflammation is an important risk factor for various human diseases. Thus, suppressing chronic inflammation has the potential to delay, prevent, and control various chronic diseases, including cerebrovascular, cardiovascular, joint, skin, pulmonary, blood, lymph, liver, pancreatic, and intestinal diseases. Various natural products from traditional Chinese medicine (TCM have been shown to safely suppress proinflammatory pathways and control inflammation-associated disease. In vivo and/or in vitro studies have demonstrated that anti-inflammatory effects of TCM occur by inhibition of the expression of master transcription factors (for example, nuclear factor-κB (NF-κB, pro-inflammatory cytokines (for example, tumor necrosis factor-α (TNF-α, chemokines (for example, chemokine (C-C motif ligand (CCL-24, intercellular adhesion molecule expression and pro-inflammatory mediators (for example, inducible nitric oxide synthase (iNOS and cyclooxygenase 2 (COX2. However, a handful of review articles have focused on the anti-inflammatory activities of TCM and explore their possible mechanisms of action. In this review, we summarize recent research attempting to identify the anti-inflammatory constituents of TCM and their molecular targets that may create new opportunities for innovation in modern pharmacology.

    Full Text Available Abstract: Cembrane-type diterpenoids are among the most frequently encountered natural products from the soft corals of the genus Lobophytum. In the course of our investigation to identify anti-inflammatory constituents from a wild-type soft coral Lobophytum crassum, two new cembranoids, lobophyolide A (1 and B (2, along with five known compounds (3–7, were isolated. The structures of these natural products were identified using NMR and MS spectroscopic analyses. Compound 1 was found to possess the first identified α-epoxylactone group among all cembrane-type diterpenoids. The in vitro anti-inflammatory effect of compounds 1–5 was evaluated. The results showed that compounds 1–5 not only reduced IL-12 release, but also attenuated NO production in LPS-activated dendritic cells. Our data indicated that the isolated series of cembrane-type diterpenoids demonstrated interesting structural features and anti-inflammatory activity which could be further developed into therapeutic entities.

    Pholiota nameko polysaccharide (PNPS-1) has been isolated and purified by enzymatic hydrolysis, hot water extraction, ethanol precipitation, and ion-exchange and gel-filtration chromatography. The anti-inflammatory activity of PNPS-1 was evaluated in rodents using xylene-induced ear edema, egg albumin-, carrageenin-, and formaldehyde-induced paw edema, cotton pellet granuloma test, adhesion of peritoneal leukocytes in vitro, and ulcerogenic activity. The results showed that PNPS-1 (5 mg/ear) inhibited topical edema in the mouse ear and at 100, 200, and 400 mg/kg (intraperitoneally) it significantly suppressed the development of egg albumin-, carrageenin-, and formaldehyde-induced paw edema in the animals. PNPS-1 (100, 200, and 400 mg/kg, per oral) significantly inhibited the growth of granuloma tissues induced by subcutaneously implanted cotton pellets in rats by 10.96, 18.07, and 43.75%, respectively. PNPS-1 also inhibited spontaneous and phorbol-12-myristate-13-acetate-activated adhesion of peritoneal leukocytes in vitro. Further, both acute as well as chronic administration of PNPS-1 (100, 200, and 400 mg/kg, per oral) did not produce any gastric lesion in rats. In conclusion, these data indicated that PNPS-1 possesses significant anti-inflammatory activity suggesting its potential as an anti-inflammatory agent for use in the treatment of various inflammatory-related diseases.

    Full Text Available Antarctic benthos was prospected in search for anti-inflammatory activity in polar benthic invertebrates, in two different geographical areas: deep-bottoms of the Eastern Weddell Sea and shallow-waters of the South Shetland Islands. A total of 36 benthic algae and invertebrate species were selected to perform solubility tests in order to test them for anti-inflammatory activity. From these, ethanol extracts of ten species from five different phyla resulted suitable to be studied in cell macrophage cultures (RAW 264.7. Cytotoxicity (MTT method and production of inflammatory mediators (prostaglandin E2, leukotriene B4, interleukin-1 were determined at three extract concentrations (50, 125, 250 g/mL. Bioassays resulted in four different species showing anti-inflammatory activity corresponding to three sponges: Mycale (Oxymycale acerata, Isodictya erinacea, and I. toxophila; and one hemichordate: Cephalodiscus sp. These results show that Antarctic sessile invertebrates may have great value as a source of lead compounds with potential pharmaceutical applications.

    Immunoglobulin G (IgG) is a central mediator of host defense due to its ability to recognize and eliminate pathogens. The recognition and effector responses are encoded on distinct regions of IgGs. The diversity of the antigen recognition Fab domains accounts for IgG's ability to bind with high specificity to essentially any antigen. Recent studies have indicated that the Fc effector domain also displays considerable heterogeneity, accounting for its complex effector functions of inflammation, modulation and immune suppression. Therapeutic anti-tumor antibodies, for example, require the pro-inflammatory properties of the IgG Fc to eliminate tumor cells, while the anti-inflammatory activity of Intravenous Immunoglobulin G (IVIG) requires specific Fc glycans for activity. In particular, the anti-inflammatory activity of IVIG is ascribed to a small population of IgGs in which the Asn297-linked complex N-glycans attached to each Fc CH2 domain include terminal α2,6-linked sialic acids. We used chemoenzymatic glycoengineering to prepare fully di-sialylated IgG Fc and solved its crystal structure. Comparison of the structures of asialylated Fc, sialylated Fc, and F241A Fc, a mutant that displays increased glycan sialylation, suggests that increased conformational flexibility of the CH2 domain is associated with the switch from pro- to anti-inflammatory activity of the Fc.

    Full Text Available BACKGROUND: To explain observed differences during SPF determination using either an in vivo or in vitro method, we hypothesized on the presence of ingredients having anti-inflammatory properties. METHODOLOGY/PRINCIPAL FINDINGS: To research our hypothesis, we studied the 21 UV filters both available on the market and authorized by European regulations and subjected these filters to the phorbol-myristate-acetate test using mice. We then catalogued the 13 filters demonstrating a significant anti-inflammatory effect with edema inhibition percentages of more than 70%. The filters are: diethylhexyl butamido triazone (92%, benzophenone-5 and titanium dioxide (90%, benzophenone-3 (83%, octocrylène and isoamyl p-methoxycinnamate (82%, PEG-25 PABA and homosalate (80%, octyl triazone and phenylbenzimidazole sulfonic acid (78%, octyl dimethyl PABA (75%, bis-ethylhexyloxyphenol methoxyphenyl triazine and diethylamino hydroxybenzoyl hexylbenzoate (70%. These filters were tested at various concentrations, including their maximum authorized dose. We detected a dose-response relationship. CONCLUSIONS/SIGNIFICANCE: The anti-inflammatory effect of a sunscreen ingredient may affect the in vivo SPF value.

    Full Text Available We investigated the anti-inflammatory activity of Senecio salignus. This medicinal plant is often used in Mexico for the treatment of fever and rheumatism. Chloroform and methanol extracts of the plant were tested on 12-O-tetradecanoylphorbol-13-acetate- (TPA- induced edema in mice ears. The methanol extract of the plant inhibited edema by 36±4.4% compared with the control, while the chloroform extract exhibited an even greater level of inhibition (64.1%. The chloroform extract was then fractionated, and the composition of the active fraction was determined by GC-MS. The anti-inflammatory activity of this fraction was then tested on TPA-induced ear edema in mice, and we found that the active fraction could inhibit edema by 46.9%. The anti-inflammatory effect of the fraction was also tested on carrageenan-induced paw edema in rats at doses of 100 mg/kg; a 58.9±2.8% reduction of the edema was observed 4 h after administration of carrageenan, and the effect was maintained for 5 h.

    We report an evaluation of the cytotoxicity of a series of electron-deficient (16-electron) half-sandwich precious metal complexes of ruthenium, osmium and iridium ([Os/Ru( η 6 - p -cymene)(1,2-dicarba- closo -dodecarborane-1,2-dithiolato)] ( 1/2 ), [Ir( η 5 -pentamethylcyclopentadiene)(1,2-dicarba- closo -dodecarborane-1,2-dithiolato)] ( 3 ), [Os/Ru( η 6 - p -cymene)(benzene-1,2-dithiolato)] ( 4/5 ) and [Ir( η 5 -pentamethylcyclopentadiene)(benzene-1,2-dithiolato)] ( 6 )) towards RAW 264.7 murine macrophages and MRC-5 fibroblast cells. Complexes 3 and 6 were found to be non-cytotoxic. The anti-inflammatory activity of 1-6 was evaluated in both cell lines after nitric oxide (NO) production and inflammation response induced by bacterial endotoxin lipopolysaccharide (LPS) as the stimulus. All metal complexes were shown to exhibit dose-dependent inhibitory effects on LPS-induced NO production on both cell lines. Remarkably, the two iridium complexes 3 and 6 trigger a full anti-inflammatory response against LPS-induced NO production, which opens up new avenues for the development of non-cytotoxic anti-inflammatory drug candidates with distinct structures and solution chemistry from that of organic drugs, and as such with potential novel mechanisms of action.

    Full Text Available The objective of this study was to perform phytochemical screening, to determine the content of phenolic compound, to evaluate antioxidant, anti-inflammatory and antiangiogenic activities of ethanol, water-ethanol and water extracts of Lophira procera. Antioxidant activity was determined by 2,2-diphenyl-1-picrylhydrazyl (DPPH and phosphomolybdenum assay, anti-inflammatory activity by proteins denaturation inhibition and membranes stabilization test and antiangiogenic activity by chicken chorioallantoic membrane (CAM method. The results showed that this plant is rich in saponins, polyphenols, tannins, total flavonoids, proanthocyanidins and coumarins. Extracts presented a strong antioxidant activity (IC50 values of 5.452 ± 0.119 μg/mL and 6.346 ± 0.544 μg/mL and respective AAI of 9.173 ± 0.203 and 7.919 ± 0.711. Excellent anti-inflammatory activity was also observed (IC50 = 16.952 ± 1.897 and IC50 = 23.172 ± 0.066 μg/mL for inhibition of protein denaturation and membrane stabilization respectively. Finally, extracts manifested a very good anti-angiogenic activity (with inhibitions ranging from 57.142 ± 0.124% to 100%. These biological activities are certainly due to high content of phenolic compound. This is the first study to report the phytochemical screening, the content of phenolic compound, the antioxidant, anti-inflammatory and antiangiogenic activities of extract derived from Lophira procera. The use of this plant in traditional medicine against ulcers, breast cancer, kidney and dental pain is therefore justified and its potential as a candidate for bioactive therapeutic molecule.

    Hancornia speciosa Gomes (Apocynaceae), popularly known as "mangabeira," has been used in folk medicine to treat inflammatory disorders, hypertension, dermatitis, diabetes, liver diseases and gastric disorders. Although the ethnobotany indicates that its fruits can be used for the treatment of ulcers and inflammatory disorders, only few studies have been conducted to prove such biological activities. This study investigated the anti-inflammatory properties of the aqueous extract of the fruits of H. speciosa Gomes as well as its bioactive compounds using in vivo experimental models. The bioactive compounds were identified by High Performance Liquid Chromatography coupled with diode array detector (HPLC-DAD) and Liquid Chromatography coupled with Mass Spectrometry (LC-MS). The anti-inflammatory properties were investigated through in vivo tests, which comprised xylene-induced ear edema, carrageenan-induced peritonitis and zymosan-induced air pouch. The levels of IL-1β, IL-6, IL-12 and TNF-α were determined using ELISA. Rutin and chlorogenic acid were identified in the extract as the main secondary metabolites. In addition, the extract as well as rutin and chlorogenic acid significantly inhibited the xilol-induced ear edema and also reduced the cell migration in both carrageenan-induced peritonitis and zymosan-induced air pouch models. Reduced levels of cytokines were also observed. This is the first study that demonstrated the anti-inflammatory activity of the extract of H. speciosa fruits against different inflammatory agents in animal models, suggesting that its bioactive molecules, especially rutin and chlorogenic acid are, at least in part, responsible for such activity. These findings support the widespread use of Hancornia speciosa in popular medicine and demonstrate that its aqueous extract has therapeutical potential for the development of herbal drugs with anti-inflammatory properties.

    Nonsteroidal anti-inflammatory drug (NSAID)-induced small intestinal damage is a serious problem in patients, but effective therapy is not available at present. The effects of feeding conditions and dietary fiber (DF) on NSAID-induced gastrointestinal lesions were examined in mice. NSAIDs (indomethacin, diclofenac, loxoprofen, aspirin) were administered to male mice in various feeding conditions. Gastrointestinal lesions were examined 24 h after NSAID dosing. Regular diets, dietary-fiber-free diet (FFD), and diets supplemented with various types of DF were given to mice. NSAIDs produced marked ulcers and perforations selectively in the gastric antrum when they were administered after feeding of regular diet for 2 h after a 22-h fast. When NSAIDs, except for aspirin, were administered in unfasted conditions, they caused marked lesions in the small intestine. When mice were given FFD, antral ulcers and intestinal lesions induced by indomethacin (30 mg/kg, s.c.) markedly decreased, but when cellulose, an insoluble DF, was added to FFD, the lesions appeared again. The addition of pectin, a soluble DF, to regular diet containing 4.1 % crude fiber significantly inhibited the formation of antral ulcers as well as intestinal lesions caused by indomethacin or diclofenac (100 mg/kg, s.c.). The results indicated that NSAIDs given after feeding of diet produced ulcers selectively in the gastric antrum. The severity of the gastrointestinal lesions depended on the concentration of soluble or insoluble DF in food. Our results suggest that soluble DF such as pectin may be a safe means for protecting the gastrointestinal mucosa against NSAIDs.

    Full Text Available Background Peptic ulcer etiology has been changing because of H. pylori decline. Objectives To estimate peptic ulcer prevalence in 10 years-interval and compare the association with H. pylori and use of non-steroidal anti-inflammatory drugs. Methods Records assessment in two periods: A (1997-2000 and B (2007-2010, searching for peptic ulcer, H. pylori infection and non-steroidal anti-inflammatory drugs use. Results Peptic ulcer occurred in 30.35% in A and in 20.19% in B. H. pylori infection occurred in 73.3% cases in A and in 46.4% in B. Non-steroidal anti-inflammatory drugs use was 3.5% in A and 13.3% in B. Neither condition occurred in 10.4% and 20.5% in A and B respectively. Comparing both periods, we observed reduction of peptic ulcer associated to H. pylori (P=0.000, increase of peptic ulcer related to non-steroidal anti-inflammatory drugs (P=0.000 and idiopathic peptic ulcer (P=0.002. The concurrent association of H. pylori and non-steroidal anti-inflammatory drugs was also higher in B (P=0.002. Rates of gastric ulcer were higher and duodenal ulcer lower in the second period. Conclusions After 10 years, the prevalence of peptic ulcer decreased, as well as ulcers related to H. pylori whereas ulcers associated to non-steroidal anti-inflammatory drugs increased. There was an inversion in the pattern of gastric and duodenal ulcer and a rise of idiopathic peptic ulcer.

    Drug-induced thrombocytopenic purpura is a skin condition result from a low platelet count due to drug-induced anti-platelet antibodies caused by drugs. Drug-induced thrombocytopenic purpura should be suspected when a patient, child or adult, has sudden, severe thrombocytopenia. Drug-induced thrombocytopenic purpura is even more strongly suspected when a patient has repeated episodes of sudden, severe thrombocytopenia

    Female Wistar rats were treated with single exposure irradiation to 2 cm of distal colon to cause radiation proctitis. All animals were evaluated by examination, colonoscopy and histologic evaluation for changes post-irradiation. Exposures of 10, 12.5, 15, 17.5, 20, 22.5, 25, 27.5 and 30 Gy caused dose-related clinical and histologic changes peaking at 7 to 15 days post-exposure. Rats treated with 20 Gy were colonoscoped and biopsied daily and showed sequential post-irradiation endoscopic changes ranging from mucosal edema and mild inflammatory changes to erosion and ulcers. Histologically, crypt abscess and mural wall necrosis similar to changes found in the human rectum after radiotherapy were noted. Treatment with nonsteroidal anti-inflammatory agents, (aspirin, indomethacin, piroxicam), misoprostol (a prostaglandin E1 analogue), or sucralfate (an anti-ulcer agent) did not ameliorate nor exacerbate radiation proctitis in rats exposed to 22.5 Gy. We conclude from these data that the female Wistar rat is a good model for studying radiation proctitis because endoscopic, histologic, and clinical changes seen post-exposure closely resemble those found in man

  6. Quality of Life in Arthritis Patients Using Nonsteroidal Anti-Inflammatory Drugs

    Directory of Open Access Journals (Sweden)

    Ingela Wiklund

    1999-01-01

    Full Text Available Arthritis is a painful and disabling condition. To suppress the pain and the inflammatory process, patients are often chronic nonsteroidal anti-inflammatory drug (NSAID users. Chronic use of NSAIDs may induce peptic ulcer, dyspeptic problems and heartburn. Therefore, these patients are often provided with treatment to relieve and/or protect against gastrointestinal problems. Rheumatic disorders also affect a range of health-related quality of life domains. In one study, patients with NSAID-associated gastroduodenal lesions complained about lack of energy, sleep disturbances, emotional distress and social isolation in addition to pain and mobility limitations. The degree of distress and dysfunction differed markedly from scores in an unselected population. Clinical trial data suggest that acid-suppressing therapy with omeprazole is superior to therapy with misoprostol and ranitidine in healing gastroduodenal lesions and preventing abdominal pain, heartburn and indigestion symptoms during continued NSAID treatment. Because arthritic patients are severely incapacitated by their condition regarding most aspects of health-related quality of life, it is important to offer a treatment that is effective in healing and preventing NSAID-induced ulcers and gastrointestinal symptoms during continued NSAID treatment without further compromising the patients’ quality of life. Treatment with omeprazole once daily has been shown to be superior to that with ranitidine and misoprostol in this respect.

    Mangifera indica is widely found in Brazil, and its leaves are used as an anti-inflammatory agent in folk medicine. The aim of this study is to perform composition analysis of essential oils from the M. indica varieties, espada (EOMIL1) and coração de boi (EOMIL2), and confirm their anti-inflammatory properties. Twenty-three volatile compounds were identified via gas chromatography-mass spectrometry (GC-MS) in two essential oils from the leaves. Paw edema and myeloperoxidase (MPO) activity were evaluated using the carrageenan-induced paw model, while leukocyte migration was analyzed using the pleurisy model. At oral doses of 100 and 300 mg/kg, the essential oils significantly reduced edema formation and the increase in MPO activity induced by carrageenan in rat paws. For a dose of 300 mg/kg EOMIL1, 62 ± 8% inhibition of edema was observed, while EOMIL2 led to 51 ± 7% inhibition of edema. At a dose of 100 mg/kg, the inhibition was 54 ± 9% for EOMIL1 and 37 ± 7% for EOMIL2. EOMIL1 and EOMIL2 significantly reduced MPO activity at doses of 100 mg/kg (47 ± 5 and 23 ± 8%, respectively) and 300 mg/kg (50 ± 9 and 31 ± 7%, respectively). In the pleurisy model, inhibitions were also observed for EOMIL1 and EOMIL2 in the leukocyte migration test. The results of the present study show that essential oils from M. indica differ in chemical composition and anti-inflammatory activity in rats.

    Fluridone is a herbicide extensively utilized in agriculture for its documented safety in animals. Fluridone contains a 4(1H)-pyridone and a trifluoromethyl-benzene moiety, which are also present in molecules with analgesic and anti-inflammatory properties. The established absence of adverse effects of Fluridone on animals prompted us to investigate whether it could represent a new anti-inflammatory compound targeting human cells. In stimulated human monocytes, micromolar Fluridone inhibited cyclooxygenase-2 expression and the release of monocyte chemoattractant protein-1 and prostaglandin-E2, to a similar extent as Acetylsalicylic acid. Fluridone also inhibited the proliferation of aortic smooth muscle cells and reduced proliferation and cytokine release by human activated lymphocytes. The mechanism of Fluridone seems to rely on the dose-dependent inhibition of the nuclear translocation of nuclear factor-κB, a transcription factor playing a pivotal role in inflammation. Fluridone also inhibited the release from stimulated human monocytes of abscisic acid, a plant stress hormone recently discovered also in mammalian cells, where it stimulates pro-inflammatory responses. Interestingly, the mechanism of Fluridone's toxicity in plants relies on the inhibition of the enzyme phytoene desaturase, involved in the biosynthetic pathway of ß-carotene, the precursor of absciscic acid in plants. Finally, administration of Fluridone reduced peritoneal inflammation in Zymosan-treated mice. These results suggest that Fluridone could represent a new prototype of anti-inflammatory drug, also active on abscisic acid pro-inflammatory pathway. © 2013 Elsevier B.V. All rights reserved.

    Paricalcitol, a selective vitamin D receptor activator, is used to treat secondary hyperparathyroidism in kidney transplant patients. Experimental and clinical studies in non-transplant kidney disease patients have found this molecule to have anti-inflammatory properties. In this exploratory study, we evaluated the anti-inflammatory profile of paricalcitol in kidney-transplant recipients. Thirty one kidney transplant recipients with secondary hyperparathyroidism completed 3 months of treatment with oral paricalcitol (1μg/day). Serum concentrations and gene expression levels of inflammatory cytokines in peripheral blood mononuclear cells were analysed at the beginning and end of the study. Paricalcitol significantly decreased parathyroid hormone levels with no changes in calcium and phosphorous. It also reduced serum concentrations of interleukin (IL)-6 and tumour necrosis factor-alpha (TNF-α) by 29% (P<0.05) and 9.5% (P<0.05) compared to baseline, respectively. Furthermore, gene expression levels of IL-6 and TNF-α in peripheral blood mononuclear cells decreased by 14.1% (P<0.001) and 34.1% (P<0.001), respectively. The ratios between pro-inflammatory cytokines (TNF-α and IL-6) and anti-inflammatory cytokines (IL-10), both regarding serum concentrations and gene expression, also experienced a significant reduction. Paricalcitol administration to kidney transplant recipients has been found to have beneficial effects on inflammation, which may be associated with potential clinical benefits.

    Full Text Available Thymoquinone (TQ, 2-Isopropyl-5-methyl-1, 4-benzoquinone, is one of the most active ingredients of Nigella Sativa seeds. TQ has a variety of beneficial properties including anti-oxidative and anti-inflammatory activities. Studies have provided original observations on the role of oxidative stress and inflammation in the development of renal diseases such as glomerulo-nephritis and drug-induced nephrotoxicity. The renoprotective effects of TQ have been demons-trated in animal models. Also, TQ has been used successfully in treating allergic diseases in humans. The aim of this review is to highlight the importance of reactive oxygen species in renal pathophysiology and the intriguing possibility for a role of TQ in the prevention of and/or protection from renal injury in humans.

    The underlying role of inflammation in atherosclerosis has been characterized. However, current treatment of coronary artery disease (CAD) predominantly consists of targeted reductions in serum lipoprotein levels rather than combating the deleterious effects of acute and chronic inflammation. Vascular inflammation acts by a number of different molecular and cellular pathways to contribute to atherogenesis. Over the last decades, both basic studies and clinical trials have provided evidence for the potential benefits of treatment of inflammation in CAD. During this period, development of pharmacotherapies directed towards inflammation in atherosclerosis has accelerated quickly. This review will highlight specific therapies targeting interleukin-1β (IL-1β), P-selectin and 5-lipoxygenase (5-LO). It will also aim to examine the anti-inflammatory effects of serpin administration, colchicine and intravenous HDL-directed treatment of CAD. We summarize the mechanistic rationale and evidence for these novel anti-inflammatory treatments at both the experimental and clinical levels. Copyright © 2015 Elsevier Ireland Ltd.

    Full Text Available Caesalpinia ferrea Mart. belongs to the family Fabaceae. Known as pau-ferro and jucá, it is used in folk medicine to treat diabetes, as antipyretic and antirheumatic. This study aimed to evaluate the anti-inflammatory and antinociceptive activities of the ethanol extract of the fruits of C. ferrea (EECf. In the evaluation of anti-inflammatory activity, EECf (50 mg/kg produced significantly inhibition of ear edema by 66.6% compared to control. Indomethacin (10 mg/kg showed inhibition of 83.9% compared to control. EECf (50 mg/kg inhibited of vascular permeability induced by acetic acid and was also able to reduce of cell migration to the peritoneal cavity induced by thioglycolate. In the writhing test induced by acid acetic, EECf (12.5, 25 and 50 mg/kg significantly reduced the number of contortions by 24.9, 46.9 and 74.2%, respectively. In the formalin test, EECf presented effects only in the second phase. The results provided experimental evidence for the effectiveness of the traditional use of C. ferrea in treating various diseases associated with inflammation and pain.

  17. Melatonin as an Anti-Inflammatory Agent Modulating Inflammasome Activation

    Directory of Open Access Journals (Sweden)

    Gaia Favero

    2017-01-01

    Full Text Available Inflammation may be defined as the innate response to harmful stimuli such as pathogens, injury, and metabolic stress; its ultimate function is to restore the physiological homeostatic state. The exact aetiology leading to the development of inflammation is not known, but a combination of genetic, epigenetic, and environmental factors seems to play an important role in the pathogenesis of many inflammation-related clinical conditions. Recent studies suggest that the pathogenesis of different inflammatory diseases also involves the inflammasomes, intracellular multiprotein complexes that mediate activation of inflammatory caspases thereby inducing the secretion of proinflammatory cytokines. Melatonin, an endogenous indoleamine, is considered an important multitasking molecule with fundamental clinical applications. It is involved in mood modulation, sexual behavior, vasomotor control, and immunomodulation and influences energy metabolism; moreover, it acts as an oncostatic and antiaging molecule. Melatonin is an important antioxidant and also a widespread anti-inflammatory molecule, modulating both pro- and anti-inflammatory cytokines in different pathophysiological conditions. This review, first, gives an overview concerning the growing importance of melatonin in the inflammatory-mediated pathological conditions and, then, focuses on its roles and its protective effects against the activation of the inflammasomes and, in particular, of the NLRP3 inflammasome.

    Elafin is a low molecular weight protein with antileukoproteinase, anti-inflammatory, antibacterial and immunomodulating properties. The profile of Elafin in fetal membranes is not well characterized. This study determined the changes in Elafin expression and concentration in human fetal membrane from patients with preterm prelabor rupture of membranes (PPROM) and in vitro in response to intra-amniotic polymicrobial pathogens. Elafin messenger RNA (mRNA) expressions were studied in fetal membranes from PPROM, normal term as well as in normal term not in labor membranes in an organ explant system treated (24 h) with lipopolysaccharide (LPS), using quantitative reverse transcription-polymerase chain reaction (RT-PCR). Enzyme-linked immunosorbent assay (ELISA) measured Elafin concentrations in culture supernatants from tissues treated with LPS and polybacterial combinations of heat-inactivated Mycoplasma hominis (MH), Ureaplasma urealyticum (UU) and Gardnerella vaginalis (GV). Elafin mRNA expression in fetal membranes from women with PPROM was significantly higher compared to women who delivered at term after normal pregnancy (5.09±3.50 vs. 11.71±2.21; Pmembranes showed a significantly increased Elafin m-RNA expression (Pmembranes also showed no changes in Elafin protein concentrations compared to untreated controls. Higher Elafin expression in PPROM fetal membranes suggests a host response to an inflammatory pathology. However, lack of Elafin response to LPS and polymicrobial treatment is indicative of the minimal anti-inflammatory impact of this molecule in fetal membranes.

    Chalcone or (E)-1,3-diphenyl-2-propene-1-one scaffold has gained considerable scientific interest in medicinal chemistry owing to its simple chemistry, ease in synthesizing a variety of derivatives and exhibiting a broad range of promising pharmacological activities by modulating several molecular targets. A number of natural and (semi-) synthetic chalcone derivatives have demonstrated admirable anti-inflammatory activity due to their inhibitory potential against various therapeutic targets like Cyclooxygenase (COX), Lipooxygenase (LOX), Interleukins (IL), Prostaglandins (PGs), Nitric Oxide Synthase (NOS), Leukotriene D4 (LTD4), Nuclear Factor-κB (NF- κB), Intracellular Cell Adhesion Molecule-1 (ICAM-1), Vascular Cell Adhesion Molecule-1 (VCAM-1), Monocyte Chemoattractant Protein-1 (MCP-1) and TLR4/MD-2, etc. The chalcone scaffold with hydroxyl, methoxyl, carboxyl, prenyl group and/or heterocyclic ring substitution like thiophene/furan/indole showed promising anti-inflammatory activity. In this review, a comprehensive study (from the year 1991 to 2016) on multi-targets of inflammatory interest, related inflammation reactions and their treatment by chalcone-based inhibitors acting on various molecular targets entailed in inflammation, Structure-Activity Relationships (SARs), Mechanism of Actions (MOAs), and patents are highlighted.

    1991-06-01

    Lyophilised aqueous extract of Euphorbia hirta L. (Euphorbiaceae) has been evaluated for analgesic, antipyretic and anti-inflammatory properties in mice and rats, in order to complete its activity profile, after the confirmation of the existence of a central depressant activity particularly expressed by a strong sedative effect, associated with anxiolytic effects. This study leads us to the conclusion that this plant extract exerts central analgesic properties. Such a dose-dependent action was obtained against chemical (writhing test) and thermic (hot plate test) stimuli, respectively, from the doses of 20 and 25 mg/kg and it was inhibited by a naloxone pretreatment, a specific morphinic antagonist compound. An antipyretic activity was obtained at the sedative doses of 100 and 400 mg/kg, on the yeast-induced hyperthermia. Finally, significant and dose-dependent anti-inflammatory effects were observed on an acute inflammatory process (carrageenan-induced edema test in rats) from the dose of 100 mg/kg. On the other hand, plant extract remained inactive on chronic processes such as Freund's adjuvant-induced rheumatoid arthritis, after a chronic treatment during fourteen days at the daily dose of 200 or 400 mg/kg; however, if inefficacy was observed on rat backpaws edema and on loss of weight, the aqueous extract reduced the inflammatory hyperalgia.

    Cordyceps militaris (bei-chong-chaw, northern worm grass) is a precious and edible entomopathogenic fungus, which is widely used in traditional Chinese medicine (TCM) as a general booster for the nervous system, metabolism, and immunity. Saccharides, nucleosides, mannitol, and sterols were isolated from this fungus. The biological activity of C. militaris was attributed to the saccharide and nucleoside contents. In this study, the aqueous methanolic fraction of C. militaris fruiting bodies exhibited a significant anti-inflammatory activity. Bioactivity-guided fractionation of the active fraction led to the isolation of eight compounds, including one new and two known cerebrosides (ceramide derivatives), two nucleosides, and three sterols. Cordycerebroside A (1), the new cerebroside, along with soyacerebroside I (2) and glucocerebroside (3) inhibited the accumulation of pro-inflammatory iNOS protein and reduced the expression of COX-2 protein in LPS-stimulated RAW264.7 macrophages. This is the first study on the isolation of cerebrosides with anti-inflammatory activity from this TCM.

    Anti-inflammatory enzymes promote the dissolution and excretion of sticky phlegm, clean the wound surface and accelerate drug diffusion to the lesion. They play important roles in treating different types of inflammation and pain. Currently, various formulations of anti-inflammatory enzymes are successfully prepared to improve the enzymatic characteristics, pharmacokinetic properties and anti-inflammatory efficacies. The work was performed by systematically searching all available literature. An overall summary of current research about various anti-inflammatory enzymes and their novel formulations is presented. The original and improved enzymatic characteristics, pharmacokinetic properties, action mechanisms, clinical information, storage and shelf life, treatment efficacies of anti-inflammatory enzymes and their different formulations are summarized. The influencing factors such as enzyme type, source, excipient, pharmaceutical technique, administration route and dosage are analyzed. The combined application of enzymes and other drugs are included in this paper. Anti-inflammatory enzymes were widely applied in treating different types of inflammation and diseases with accompanying edema. Their novel formulations increased enzymatic stabilities, improved pharmacokinetic properties, provided different administration routes, and enhanced anti-inflammatory efficacies of anti-inflammatory enzymes but decreased side effects and toxicity. Novel enzyme formulations improve and expand the usage of anti-inflammatory enzymes. Copyright © 2017 Elsevier B.V. All rights reserved.

    Full Text Available In this paper, we present novel bioactivity for barettin isolated from the marine sponge Geodia barretti. We found that barettin showed strong antioxidant activity in biochemical assays as well as in a lipid peroxidation cell assay. A de-brominated synthetic analogue of barettin did not show the same activity in the antioxidant cell assay, indicating that bromine is important for cellular activity. Barettin was also able to inhibit the secretion of the inflammatory cytokines IL-1β and TNFα from LPS-stimulated THP-1 cells. This combination of anti-inflammatory and antioxidant activities could indicate that barettin has an atheroprotective effect and may therefore be an interesting product to prevent development of atherosclerosis.

    Berberine sulfate (Ber) 40 and 80 mg/kg ig reduced the purging effects of castor oil or Cassia angustifolia leaf in mice, but did not affect the gastrointestinal transport function of Chinese ink in normal mice. Ber 60 mg/kg ig significantly inhibited the increased vascular permeability induced by ip 0.7% acetic acid in mice. Ber 20 and 50 mg/kg sc markedly inhibited the increased vascular permeability induced by histamine 100 micrograms/0.1 ml ic in rats. Ber 4 and 8 mg/kg sc produced obvious inhibition in the xylene-induced swelling of mouse ear. The anti-inflammatory effects were enhanced in a dose-dependent manner. It is suggested that the antidiarrheal effect of Ber is relative to its restriction against exudative inflammation to a certain extent.

    In this second article we describe the more interesting pharmacological interactions in dental practice based on the prescription of analgesic narcotics, paracetamol and non-selective non-steroid anti-inflammatory drugs (NSAI) (which inhibit cyclooxigenase 1 -COX 1- and cyclooxigenase 2 -COX 2-) and selective NSAIs (COX 2 inhibitors). The importance of preventing the appearance of these pharmacological interactions is because these are medicaments prescribed daily in odontology for moderate pain treatment and inflammation in the oral cavity. Paracetamol can interact with warfarin and therefore care should be taken with chronic alcoholic patients. All NSAIs reduce renal blood flow and consequently are capable of reducing the efficacy of medicaments used for treating arterial hypertension, which act via a renal mechanism. Especial attention should be taken considering the risk of interaction between the antagonists of AT1 receptors of angiostensin II (ARAII) and the NSAIs.

    Biological activities of five Veronica species (Scrophulariaceae), V. cymbalaria, V. hederifolia, V. pectinata var. glandulosa, V. persica and V. polita were studied for their anti-inflammatory and cytotoxic activities. Their methanol extracts showed both the inhibitory activity of nitric oxide (NO) production in lipopolysaccharide (LPS)-stimulated macrophages and cytotoxic activity against KB epidermoid carcinoma and B16 melanoma. When the methanol extracts were fractionated between water and chloroform, water fractions significantly inhibited NO production without any cytotoxicity, while chloroform fractions showed cytotoxicity dose-dependently. When the radical scavenging activity was determined using 2,2-diphenyl-1-picryl-hydrazyl (DPPH), water fractions of the five Veronica species scavenged free radicals effectively, suggesting that the inhibitory effect of this species on NO production was due to their radical scavenging activity. On the other hand, chloroform fractions of Veronica species except for V. cymbalaria showed similar cytotoxic activity against KB and B16 melanoma cells.

    Rheumatic heart disease remains an important cause of acquired heart disease in developing countries. Although prevention of rheumatic fever and management of recurrences have been well established, optimal management of active rheumatic carditis remains unclear. This is an update of a review published in 2003, and previously updated in 2009 and 2012. To assess the effects, both harmful and beneficial, of anti-inflammatory agents such as aspirin, corticosteroids and other drugs in preventing or reducing further valvular damage in patients with acute rheumatic fever. We searched the Cochrane Central Register of Controlled Trials (2013, Issue 9 of 12), MEDLINE (Ovid, 1948 to 2013 October Week 1), EMBASE (Ovid, 1980 to 2013 Week 41) and Latin American Caribbean Health Sciences Literature (LILACS) (1982 to 17 October 2013). We last searched Index Medicus (1950 to April 2001) in 2001. We checked reference lists of identified studies and applied no language restrictions. Randomised controlled trials comparing anti-inflammatory agents (e.g. aspirin, steroids, immunoglobulins, pentoxifylline) versus placebo or controls, or comparing any of the anti-inflammatory agents versus one another, in adults and children with acute rheumatic fever diagnosed according to Jones, or modified Jones, criteria. The presence of cardiac disease one year after treatment was the major outcome criterion selected. Two review authors extracted data and assessed risk of bias using the methodology outlined in the Cochrane Handbook of Systematic Reviews of Interventions. Standard methodological procedures as expected by The Cochrane Collaboration were used. No new studies were included in this update. Eight randomised controlled trials involving 996 people were selected for inclusion in the review. Researchers compared several steroidal agents such as corticotrophin, cortisone, hydrocortisone, dexamethasone, prednisone and intravenous immunoglobulin versus aspirin, placebo or no treatment. Six

    To identify the compounds responsible for the antinociceptive and anti-inflammatory effects previously described for Sedum dendroideum, through bioassay-guided fractionation procedures. Antinociceptive activity was evaluated through mouse acetic acid-induced writhing model. The anti-inflammatory activity was assessed through croton oil-induced mouse ear oedema and carrageenan-induced peritonitis. The Sedum dendroideum juice afforded seven known flavonoids identified with basis on NMR data. The oral administration of the major kaempferol glycosides kaempferitrin [1] (17.29 micromol/kg), kaempferol 3-O-beta-glucopyranoside-7-O-alpha-rhamnopyranoside [2] (16.82 micromol/kg), kaempferol 3-O-neohesperidoside-7-O-alpha-rhamnopyranoside [3] (13.50 micromol/kg) or alpha-rhamnoisorobin [5] (23.13 micromol/kg) inhibited by 47.3%, 25.7%, 60.2% and 58.0%, respectively, the acetic acid-induced nociception (indomethacin: 27.95 micromol/kg, p.o.; 68.9%). Flavonoids 1, 2, 3 or 5, at the same doses, reduced by 39.5%, 46.5%, 35.6% and 33.3%, respectively, the croton oil-induced oedema (dexamethasone: 5.09 micromol/kg, s.c.; 83.7%) and impaired leukocyte migration by 42.9%, 46.3%, 50.4% and 49.6%, respectively (dexamethasone: 5.09 micromol/kg, s.c.; 66.1%). Our findings show that the major kaempferol glycosides may account for the renowned medicinal use of Sedum dendroideum against pain and inflammatory troubles.

    Full Text Available Acute lung injury (ALI is characterized by inflammation of the lung tissue and oxidative injury caused by excessive accumulation of reactive oxygen species. Studies have suggested that anti-inflammatory or antioxidant agents could be used for the treatment of ALI with a good outcome. Therefore, our study aimed to test whether the mycelium extract of Sanghuangporus sanghuang (SS-1, believed to exhibit antioxidant and anti-inflammatory properties, could be used against the excessive inflammatory response associated with lipopolysaccharides (LPS-induced ALI in mice and to investigate its possible mechanism of action. The experimental results showed that the administration of SS-1 could inhibit LPS-induced inflammation. SS-1 could reduce the number of inflammatory cells, inhibit myeloperoxidase (MPO activity, regulate the TLR4/PI3K/Akt/mTOR pathway and the signal transduction of NF-κB and MAPK pathways in the lung tissue, and inhibit high mobility group box-1 protein 1 (HNGB1 activity in BALF. In addition, SS-1 could affect the synthesis of antioxidant enzymes Heme oxygenase 1 (HO-1 and Thioredoxin-1 (Trx-1 in the lung tissue and regulate signal transduction in the KRAB-associated protein-1 (KAP1/nuclear factor erythroid-2-related factor Nrf2/Kelch Like ECH associated Protein 1 (Keap1 pathway. Histological results showed that administration of SS-1 prior to induction could inhibit the large-scale LPS-induced neutrophil infiltration of the lung tissue. Therefore, based on all experimental results, we propose that SS-1 exhibits a protective effect against LPS-induced ALI in mice. The mycelium of S. sanghuang can potentially be used for the treatment or prevention of inflammation-related diseases.

    The aim of the study was to identify the common in Georgia leguminous crops culture with pronounced antioxidant, anti-inflammatory activity. The primary evaluation of the antiinflammatory effects of beans was performed on the experimental models of MDCK and Jurkat cells model systems. Extracts of various varieties of legumes (Beans "Kidney", Meadow beans, Beans Shulavera, Batumian beans, Beans "Udelebi", green peas, peas Shulavera, lentils Lens Culinaris, Soy) were added to the intact or incubated under oxidative stress conditions Jurkat and MDCK cells. Cells' vitality was determined by MTT test. On the basis of analysis of the obtained results, we concluded that: - Meadow beans extract (low doses) revealed cytoprotective effect on the intact and incubated under oxidative stress conditions immune (Jurkat) and epithelial (MDCK) cells. High antioxidant, cytoprotective activity of this extract correlates with high polyphenols content in it. - The extract of Shulavera beans did affect the intact Jurkat and MDCK cells, but showed pronounced cytoprotective activity on these cells incubated under the oxidative stress conditions. High antioxidant, cytoprotective activity of this extract correlates with high content of polyphenols in it. - Low dose of lentils Lens Culinaris extracts revealed cytoprotective activity on the incubated under oxidative stress conditions MDCK cells, but was inactive in case of intact MDCK and incubated in different conditions immune Jurkat cells. The selective antioxidant activity of this extract is related with its other constituent components, but not polyphenols. - Despite high polyphenols content and high antioxidant activity in vivo, Batumian beans revealed moderate cytoprotective activity on intact and incubated under oxidative stress conditions Jurkat cells, suppressive activity on the intact MDCK cells and was inactive in relation to the incubated under oxidative stress conditions MDCK cells. Based on these findings, we can identify

    Croton celtidifolius Baill commonly known as "sangue-de-adave" is a tree found in the Atlantic Forest of south of Brazil, mainly in Santa Catarina. The bark and leaf infusions of this medicinal plant have been popularly used for the treatment of inflammatory diseases. In this study we evaluated the anti-inflammatory and antioxidant properties of crude extract (CE), aqueous fraction (AqF), ethyl acetate fraction (EAF), butanolic fraction (BuF) and catechin, gallocatechin and sub-fractions, 19SF, 35SF and 63SF that contained a mixture of proanthocyanidins and were derived from the EAF fraction. The CE, AqF, EAF, BuF, catechin and sub-fractions 35SF and 63SF reduced paw edema induced by carrageenan. The CE, fractions, sub-fractions and isolated compounds showed antioxidant properties in vitro, all were able to scavenge superoxide anions at a concentration of 100 microg ml(-1). The EAF, catechin and gallocatechin were most effective in the deoxyribose assay, IC50 0.69 (0.44-1.06), 0.20 (0.11-0.39), 0.55 (0.28-1.08) microg x ml(-1) respectively. The CE and other fractions and sub-fractions inhibited deoxyribose degradation up to 1 microg x ml(-1). In the hydrophobic system only AqF did not show lipid peroxidation inhibition. The CE, other fractions, sub-fractions and isolated compounds inhibited lipidid peroxidation only at a concentration of 100 microg x ml(-1). In summary, this study demonstrates that Croton celtidifolius bark has significant anti-inflammatory and antioxidant activity.

    This article reviews the latest developments in understanding the pathogenesis, detection and treatment of small intestinal damage and bleeding caused by nonsteroidal anti-inflammatory drugs (NSAIDs). With improvements in the detection of NSAID-induced damage in the small intestine, it is now clear that this injury and the associated bleeding occurs more frequently than that occurring in the stomach and duodenum, and can also be regarded as more dangerous. However, there are no proven-effective therapies for NSAID-enteropathy, and detection remains a challenge, particularly because of the poor correlation between tissue injury and symptoms. Moreover, recent studies suggest that commonly used drugs for protecting the upper gastrointestinal tract (i.e., proton pump inhibitors) can significantly worsen NSAID-induced damage in the small intestine. The pathogenesis of NSAID-enteropathy is complex, but studies in animal models are shedding light on the key factors that contribute to ulceration and bleeding, and are providing clues to the development of effective therapies and prevention strategies. Novel NSAIDs that do not cause small intestinal damage in animal models offer hope for a solution to this serious adverse effect of one of the most widely used classes of drugs. PMID:23569332

    Evidence clearly shows a chemopreventive effect for aspirin and other non-steroidal anti-inflammatory drugs (NSAIDs) on colorectal cancer and probably other cancer types; however, data on the risk-benefit profile for cancer prevention are insufficient and no definitive recommendations can be made. Aspirin has emerged as the most likely NSAID for use in chemoprevention because of its known cardiovascular benefit and available safety and efficacy data. Other traditional NSAIDs, particularly sulindac, and selective COX-2 inhibitors are now given to patients at high risk of colorectal cancer, although these drugs do not provide cardioprotection. More studies of aspirin and cancer prevention are needed to define the lowest effective dose, the age at which to initiate therapy, the optimum treatment duration, and the subpopulations for which the benefits of chemoprevention outweigh the risks of adverse side-effects. Although it might be possible to answer some of these questions with longer follow-up of existing clinical trials, randomised controlled trials with new study designs will be needed. Future projects should investigate the effects of aspirin treatment on multiple organ systems. Cancers of interest are colorectal, breast, prostate, lung, stomach, and oesophageal. The main side-effect of aspirin is peptic ulcers; therefore coadministration of aspirin with a proton-pump inhibitor is an attractive option and is under investigation in the AspECT trial.

    Cancer is one of the major causes of death worldwide, and the incidence and mortality rates of cancer are expected to rise tremendously in the near future. Despite a better understanding of cancer biology and advancement in cancer management, current strategies in cancer treatment remain costly and ineffective. Hence, instead of putting more efforts to search for new cancer cures, attention has now been shifted to the development of cancer chemopreventive agents as a preventive measure for cancer formation. It is well known that neoplastic transformation of cells is multifactorial, and the occurrence of oxidative stress, chronic inflammation, and genomic instability events has been implicated in the carcinogenesis of cells. Zinc l-carnosine (ZnC), which is clinically used as gastric ulcer treatment in Japan, has been suggested to have the potential in preventing cancer development. Multiple studies have revealed that ZnC possesses potent antioxidant, anti-inflammatory, and genomic stability enhancement effects. Thus, this review provides some mechanistic insight into the antioxidant, anti-inflammatory, and genomic stability enhancement effects of ZnC in relevance to its chemopreventive potential.

    Croton celtidifolius Bailon, commonly known as Sangue-de-Adáve or Pau-Andrade, is a tree found in the Atlantic forest of southern Brazil. It has been popularly used for the treatment of inflammatory and ulcerative disorders. Phytochemical analysis demonstrated the presence of flavonoids and proanthocyanidins in an ethyl acetate fraction (EAF) from C. celtidifolius Bailon. In this study, we have evaluated the effects of EAF and its sub-fractions (35 and 63, catechin) on inflammatory (cell migration and plasma extravasation) and oxidative (lipid peroxidation, superoxide dismutase (SOD) activity and superoxide anion production) parameters in carrageenan-induced pleurisy in rats. NO production was also measured by nitrite/nitrate levels. EAF and sub-fraction 63 (63SF) showed anti-inflammatory activity, as indicated by a reduction in plasma extravasation and cell migration (mainly polymorphonuclear leukocytes) to the pleural cavity. Furthermore, EAF treatment decreased the production of superoxide radical anion by cells isolated from the pleural cavity, while it did not affect the nitrite/nitrate levels in exudates. The results show that C. celtidifolius contains substances with antioxidant and anti-inflammatory activity that, at least in part, act by a modulation of oxidative stress by phenolic compounds.

    Historically, anti-inflammatory drugs had their origins in the serendipitous discovery of certain plants and their extracts being applied for the relief of pain, fever and inflammation. When salicylates were discovered in the mid-19th century to be the active components of Willow Spp., this enabled these compounds to be synthesized and from this, acetyl-salicylic acid or Aspirin was developed. Likewise, the chemical advances of the 19th-20th centuries lead to development of the non-steroidal anti-inflammatory drugs (NSAIDs), most of which were initially organic acids, but later non-acidic compounds were discovered. There were two periods of NSAID drug discovery post-World War 2, the period up to the 1970's which was the pre-prostaglandin period and thereafter up to the latter part of the last century in which their effects on prostaglandin production formed part of the screening in the drug-discovery process. Those drugs developed up to the 1980-late 90's were largely discovered empirically following screening for anti-inflammatory, analgesic and antipyretic activities in laboratory animal models. Some were successfully developed that showed low incidence of gastro-intestinal (GI) side effects (the principal adverse reaction seen with NSAIDs) than seen with their predecessors (e.g. aspirin, indomethacin, phenylbutazone); the GI reactions being detected and screened out in animal assays. In the 1990's an important discovery was made from elegant molecular and cellular biological studies that there are two cyclo-oxygenase (COX) enzyme systems controlling the production of prostanoids [prostaglandins (PGs) and thromboxane (TxA2)]; COX-1 that produces PGs and TxA2 that regulate gastrointestinal, renal, vascular and other physiological functions, and COX-2 that regulates production of PGs involved in inflammation, pain and fever. The stage was set in the 1990's for the discovery and development of drugs to selectively control COX-2 and spare the COX-1 that is central to

    Full Text Available The thyroid axis is particularly prone to interactions with a wide variety of drugs, whose list increases year by year. Hypothyroidism is the most frequent consequence of drug-induced thyroid dysfunction. The main mechanisms involved in the development of primary hypothyroidism are: inhibition of the synthesis and/or release of thyroid hormones, immune mechanisms related to the use of interferon and other cytokines, and the induction of thyroiditis associated with the use of tyrosine kinase inhibitors and drugs blocking the receptors for vascular endothelial growth factor. Central hypothyroidism may be induced by inhibition of thyroid-stimulating hormone (bexarotene or corticosteroids or by immunological mechanisms (anti-CTLA4 or anti-PD-1 antibody drugs. It is also important to recognize those drugs that generate hypothyroidism by interaction in its treatment, either by reducing the absorption or by altering the transport and metabolism of levothyroxine. Thus, it is strongly recommended to evaluate thyroid function prior to the prescription of medications such as amiodarone, lithium, or interferon, and the new biological therapies that show important interaction with thyroid and endocrine function in general.

    Gracilaria changii (Xia et Abbott) Abbott, Zhang et Xia, a red algae commonly found in the coastal areas of Malaysia is traditionally used for foods and for the treatment of various ailments including inflammation and gastric ailments. The aim of the study was to investigate anti-inflammatory, gastroprotective and anti-ulcerogenic activities of a mass spectrometry standardized methanolic extract of Gracilaria changii. Methanolic extract of Gracilaria changii (MeOHGCM6 extract) was prepared and standardized using mass spectrometry (MS). Anti-inflammatory activities of MeOHGCM6 extract were examined by treating U937 cells during its differentiation with 10 μg/ml MeOHGCM6 extract. Tumour necrosis factors-α (TNF-α) response level and TNF-α and interleukin-6 (IL-6) gene expression were monitored and compared to that treated by 10 nM betamethasone, an anti-inflammatory drug. Gastroprotective and anti-ulcerogenic activities of MeOHGCM6 extract were examined by feeding rats with MeOHGCM6 extract ranging from 2.5 to 500 mg/kg body weight (b.w.) following induction of gastric lesions. Production of mucus and gastric juice, pH of the gastric juice and non-protein sulfhydryls (NP-SH) levels were determined and compared to that fed by 20 mg/kg b.w. omeprazole (OMP), a known anti-ulcer drug. MS/MS analysis of the MeOHGCM6 extracts revealed the presence of methyl 10-hydroxyphaeophorbide a and 10-hydroxypheophytin a, known chlorophyll proteins and several unidentified molecules. Treatment with 10 μg/ml MeOHGCM6 extract during differentiation of U937 cells significantly inhibited TNF-α response level and TNF-α and IL-6 gene expression. The inhibitory effect was comparable to that of betamethasone. No cytotoxic effects were recorded for cells treated with the 10 μg/ml MeOHGCM6 extract. Rats fed with MeOHGCM6 extract at 500 mg/kg b.w. showed reduced absolute ethanol-induced gastric lesion sizes by > 99% (p extract of Gracillaria changii possesses anti-inflammatory

    Ficus carica Linn. (Moraceae) is commonly known as edible fig. The leaves, roots, fruits and latex of the plant are medicinally used in different diseases. The leaves are claimed to be effective in various inflammatory conditions like painful or swollen piles, insect sting and bites. However, there has been no report on anti-inflammatory and antioxidant activity of F. carica leaves. Therefore the aim of this study was to evaluate the anti-inflammatory and antioxidant activity of F. carica leaves. Our study validated the traditional claim with pharmacological data. Anti-inflammatory and antioxidant activity of the drug could be due to the presence of steroids and flavanoids, respectively, which are reported to be present in the drug. Furthermore, the anti-inflammatory activity of the drug could be due to its free radical scavenging activity. Further work is also required to isolate and characterise the active constituents responsible for the anti-inflammatory activities.

    Nepenthes mirabilis (Lour.) Rafarin (Nepenthaceae) is a carnivorous plant used as a folk medicine in the treatment of jaundice, hepatitis, gastric ulcers, ureteral stones, diarrhea, diabetes, and high blood pressure. Neither the phytochemical content nor biological activities of N. mirabilis have been reported. The anti-inflammatory activity from the N. mirabilis methanolic extract led to the isolation of compounds (1-26). Chromatographic methods were used to isolate compounds from the methanol extract of N. mirabilis branches and leaves. The anti-inflammatory activity of these isolated compounds was investigated in lipopolysaccharide (LPS)-stimulated bone marrow-derived dendritic cells (BMDCs) using ELISA. Primary BMDCs were used to examine the production of pro-inflammatory cytokines (IL-12 p40, IL-6, and TNF-α, at concentrations of 0.1, 0.2, and 1.0 μM) as compared with a positive control, SB203580 (1.0 μM). MTT assays showed that isolated compounds (1-26) did not exhibit significant cytotoxicity at concentrations up to 20.0 μM. Compound 9 showed potent inhibition of IL-12 p40, IL-6, and TNF-α production (IC50 = 0.17 ± 0.02, 0.46 ± 0.01, and 8.28 ± 0.21 μM, respectively). Compound 4 showed potent inhibition of IL-12 p40 and IL-6 production (IC50 = 1.17 ± 0.01 and 2.15 ± 0.04 μM). In addition, IL-12 p40 inhibition by naphthalene derivatives (1-7, 9, and 10), phenolic compounds (11-15), lupeone (18), and flavonoids (22, 25, and 26) was more potent than with the positive control. The isolated compounds exhibited little and/or no inhibitory effects on TNF-α production in LPS-stimulated BMDCs. Taken together, these data suggest that the isolated components have significant inhibitory effects on pro-inflammatory cytokine production and warrant further study concerning their potential medicinal use.

However, its low oral bioavailability is a major obstacle to its potential use. This study developed and optimized an AG-loaded nanoemulsion (AG-NE formulation to improve AG oral bioavailability and its protective effects against inflammatory bowel disease. Methods: A high-pressure homogenization technique was used to prepare the AG-NE and solubility, viscosity, and droplet size tests were conducted to develop the optimized AG-NE composed of α-tocopherol, ethanol, Cremophor EL, and water. The permeability was assessed using everted rat gut sac method and in vivo absorption and anti-inflammatory effect in rats was also evaluated. The plasma concentration of AG was determined using our validated high performance liquid chromatography method, which was used to generate a linear calibration curve over the concentration range of 0.1–25 µg/mL in rat plasma (R2>0.999.Results: The optimized AG-NE had a droplet size of 122±11 nm confirmed using transmission electron microscopy and a viscosity of 28 centipoise (cps. It was stable at 4 and 25°C for 90 days. An ex vitro intestinal permeability study indicated that the jejunum was the optimal site for AG absorption from the optimized AG-NE, which was 8.21 and 1.40 times higher than that from an AG suspension and AG ethanol solution, respectively. The pharmacokinetic results indicate that

    Aspirin and the newer nonsteroidal anti-inflammatory drugs are the mainstay of basic therapy in rheumatoid arthritis and the other rheumatic diseases. Despite its many years of clinical use, the pharmacologic actions of aspirin are still not fully understood; those of many of the newer nonsteroidals may offer significant advantages in terms of long-term safety. Studies in animals and normal human volunteers, as well as clinical trials, provide useful information about the absorption, metabolism, excretion, efficacy, appropriate dosage, and safety of a given nonsteroidal agent. Because all of the newer agents have been developed using the same basic animal tests of efficacy, they all closely resemble indomethacin. Differences in half-life, however, may be important in determining the relative safety of a nonsteroidal, especially in older patients. Most of the nonsteroidals bind only to albumin, and therefore have a kind of built-in safety mechanism: once the albumin binding sites are saturated, free drug is rapidly excreted by the kidney and drug accumulation is prevented. Despite this fact, the clinician must be concerned about two frequent sorts of problems that may arise from the prostaglandin-inhibiting effects of the nonsteroidals. Gastrointestinal side effects may include minor symptoms; diffuse gastritis; small erosions of the gastric mucosa, visible only by endoscope; and frank ulceration, which may rarely be life-threatening. Animal studies, various tests in normal volunteers, and pre-marketing clinical studies may all shed light on the relative ulcerogenicity of a given nonsteroidal agent. Long-term clinical experience especially helps indicate which agents appear to be more ulcerogenic than average and which appear to be less than average. Renal effects of the nonsteroidals are also related to their inhibition of prostaglandin synthesis. The most serious of these--a characteristic kind of interstitial nephritis, renal papillary necrosis, and hyperkalemia

    Inflammatory disorders are common in modern life, and medicinal plants provide an interesting source for new compounds bearing anti-inflammatory properties. In this regard, Brazilian medicinal plants are considered to be a promising supply of such compounds due to their great biodiversity. To undertake a review on Brazilian medicinal plants with corroborated anti-inflammatory activities by selecting data from the literature reporting the efficacy of plants used in folk medicine as anti-inflammatory, including the mechanisms of action of their extracts and isolated compounds. A search in the literature was undertaken by using the following Web tools: Web of Science, SciFinder, Pub-Med and Science Direct. The terms 'anti-inflammatory' and 'Brazilian medicinal plants' were used as keywords in search engine. Tropicos and Reflora websites were used to verify the origin of the plants, and only the native plants of Brazil were included in this review. The publications reporting the use of well-accepted scientific protocols to corroborate the anti-inflammatory activities of Brazilian medicinal plants with anti-inflammatory potential were considered. We selected 70 Brazilian medicinal plants with anti-inflammatory activity. The plants were grouped according to their anti-inflammatory mechanisms of action. The main mechanisms involved inflammatory mediators, such as interleukins (ILs), nuclear factor kappa B (NF-κB), prostaglandin E2 (PGE2), cyclooxygenase (COX) and reactive oxygen species (ROS). The collected data on Brazilian medicinal plants, in the form of crude extract and/or isolated compounds, showed significant anti-inflammatory activities involving different mechanisms of action, indicating Brazilian plants as an important source of anti-inflammatory compounds.

    Full Text Available Abstract Background Antidepressants are heavily prescribed drugs and have been shown to affect inflammatory signals. We examined whether these have anti-inflammatory properties in animal models of septic shock and allergic asthma. We also analysed whether antidepressants act directly on peripheral cell types that participate in the inflammatory response in these diseases. Methods The antidepressants desipramine and fluoxetine were compared in vivo to the glucocorticoid prednisolone, an anti-inflammatory drug of reference. In a murine model of lipopolysaccharides (LPS-induced septic shock, animals received the drugs either before or after injection of LPS. Circulating levels of tumour necrosis factor (TNF-α and mortality rate were measured. In ovalbumin-sensitized rats, the effect of drug treatment on lung inflammation was assessed by counting leukocytes in bronchoalveolar lavages. Bronchial hyperreactivity was measured using barometric plethysmography. In vitro production of TNF-α and Regulated upon Activation, Normal T cell Expressed and presumably Secreted (RANTES from activated monocytes and lung epithelial cells, respectively, was analysed by immunoassays. Reporter gene assays were used to measure the effect of antidepressants on the activity of nuclear factor-κB and activator protein-1 which are involved in the control of TNF-α and RANTES expression. Results In the septic shock model, all three drugs given preventively markedly decreased circulating levels of TNF-α and mortality (50% mortality in fluoxetine treated group, 30% in desipramine and prednisolone treated groups versus 90% in controls. In the curative trial, antidepressants had no statistically significant effect, while prednisolone still decreased mortality (60% mortality versus 95% in controls. In ovalbumin-sensitized rats, the three drugs decreased lung inflammation, albeit to different degrees. Prednisolone and fluoxetine reduced the number of macrophages, lymphocytes

    Leclercia adecarboxylata, a ubiquitous Gram-negative bacillus, is generally viewed as an opportunistic pathogen because it is rarely cultured from clinical samples. Although rare, bacteremia due to L. adecarboxylata tends to occur in immunocompromised hosts and patients with systemic comorbidities. Only one case of bacteremia due to L. adecarboxylata has been reported in a previously healthy patient. We describe a male patient with an active peptic ulcer who developed L. adecarboxylata bacteremia after a long-term use of nonsteroidal anti-inflammatory drugs. The abdomen is believed to have been the most probable portal of entry. After appropriate medical management, the patient recovered without sequela. Copyright © 2013. Published by Elsevier B.V.

    The use of analgesia has become standard, and appropriate, practice in avian medicine. As in mammals, pain control in avian patients is usually accomplished with opioids and nonsteroidal anti-inflammatory drugs (NSAIDs) used singly or in combination for a multimodal approach. Despite their usefulness, widespread use, and relative safety in clinical use, few controlled studies in birds have been conducted on efficacy, safety, and dosing. The guidelines for the use of NSAIDs in raptors and other birds have mainly been empirical. More recently, NSAIDs in free-living raptors have emerged as a major conservation issue with the discovery that diclofenac sodium was responsible for the population crash of three species of Gyps vultures in southern Asia. In this context, residues of veterinary NSAIDs in domestic animals are now considered environmental contaminants that can be significantly toxic to vultures and possibly other avian scavengers. Ironically, the disaster with Asian vultures has led to a considerable body of research on NSAIDs in raptors to the benefit of clinicians who now have scientific information available to help assess dosing, safety, toxicity, and pharmacokinetics of NSAIDs in their raptor patients.

  4. Anti-Inflammatory Dimethylfumarate: A Potential New Therapy for Asthma?

    Directory of Open Access Journals (Sweden)

    2013-01-01

    Full Text Available Asthma is a chronic inflammatory disease of the airways, which results from the deregulated interaction of inflammatory cells and tissue forming cells. Beside the derangement of the epithelial cell layer, the most prominent tissue pathology of the asthmatic lung is the hypertrophy and hyperplasia of the airway smooth muscle cell (ASMC bundles, which actively contributes to airway inflammation and remodeling. ASMCs of asthma patients secrete proinflammatory chemokines CXCL10, CCL11, and RANTES which attract immune cells into the airways and may thereby initiate inflammation. None of the available asthma drugs cures the disease—only symptoms are controlled. Dimethylfumarate (DMF is used as an anti-inflammatory drug in psoriasis and showed promising results in phase III clinical studies in multiple sclerosis patients. In regard to asthma therapy, DMF has been anecdotally reported to reduce asthma symptoms in patients with psoriasis and asthma. Here we discuss the potential use of DMF as a novel therapy in asthma on the basis of in vitro studies of its inhibitory effect on ASMC proliferation and cytokine secretion in ASMCs.

    Dead and dying cells release nucleic acids. These extracellular RNAs and DNAs can be taken up by inflammatory cells and activate multiple nucleic acid-sensing toll-like receptors (TLR3, 7, 8, and 9). The inappropriate activation of these TLRs can engender a variety of inflammatory and autoimmune diseases. The redundancy of the TLR family encouraged us to seek materials that can neutralize the proinflammatory effects of any nucleic acid regardless of its sequence, structure or chemistry. Herein we demonstrate that certain nucleic acid-binding polymers can inhibit activation of all nucleic acid-sensing TLRs irrespective of whether they recognize ssRNA, dsRNA or hypomethylated DNA. Furthermore, systemic administration of such polymers can prevent fatal liver injury engendered by proinflammatory nucleic acids in an acute toxic shock model in mice. Therefore these polymers represent a novel class of anti-inflammatory agent that can act as molecular scavengers to neutralize the proinflammatory effects of various nucleic acids. PMID:21844380

  6. Nonsteroidal Anti-Inflammatory Drugs and Risk of Melanoma

    2011-01-01

    Full Text Available Because nonsteroidal anti-inflammatory drugs (NSAIDs inhibit tumor growth in vitro, we investigated the association between NSAIDs and melanoma to determine if there was epidemiologic evidence of a chemopreventive effect from these medications. Three hundred twenty-seven subjects with incident melanoma and 119 melanoma-free controls completed a structured interview assessing melanoma risk factors. The unadjusted odds ratio (OR for use of nonaspirin NSAIDs was 0.58 (95% CI 0.31–1.11, in a comparison of subjects with melanoma to controls. After adjustment for melanoma risk factors, the OR was 0.71 (95% CI 0.23–2.02. Aspirin users had an unadjusted OR of 0.85 (95% CI 0.45–1.69 and an adjusted OR of 1.45 (95% CI 0.44–4.74. In this pilot study, we found no evidence of a significant association between analgesic use and melanoma risk when potential confounders are assessed. Based on conflicting reports in the literature, meta-analysis may be appropriate.

  7. The neuroimmune basis of anti-inflammatory acupuncture.

    Science.gov (United States)

    Kavoussi, Ben; Ross, B Evan

    2007-09-01

    This review article presents the evidence that the antiinflammatory actions of acupuncture are mediated via the reflexive central inhibition of the innate immune system. Both laboratory and clinical evidence have recently shown the existence of a negative feedback loop between the autonomic nervous system and the innate immunity. There is also experimental evidence that the electrical stimulation of the vagus nerve inhibits macrophage activation and the production of TNF, IL-1beta , IL-6, IL-18, and other proinflammatory cytokines. It is therefore conceivable that along with hypnosis, meditation, prayer, guided imagery, biofeedback, and the placebo effect, the systemic anti-inflammatory actions of traditional and electro-acupuncture are directly or indirectly mediated by the efferent vagus nerve activation and inflammatory macrophage deactivation. In view of this common physiological mediation, assessing the clinical efficacy of a specific acupuncture regimen using conventional double-blind placebo-controlled trials inherently lacks objectivity due to (1) the uncertainty of ancient rules for needle placement, (2) the diffuse noxious inhibitory control triggered by control-needling at irrelevant points, (3) the possibility of a dose-response relationship between stimulation and effects, and (4) the possibility of inadequate blinding using an inert sham procedure. A more objective assessment of its efficacy could perhaps consist of measuring its effects on the surrogate markers of autonomic tone and inflammation. The use of acupuncture as an adjunct therapy to conventional medical treatment for a number of chronic inflammatory and autoimmune diseases seems plausible and should be validated by confirming its cholinergicity.

    Inflammation is the symptom of many diseases like rheumatoid arthritis and osteoarthritis. Many side effects are associated with the Non-Steroidal Anti-inflammatory Drugs (NSAIDs) used as conventional treatment for these conditions. In Unani, there are large number of single and compound drugs for inflammatory conditions. One dosage form of Unani system of medicine is named as Zimad in which paste is formed by mixing powder in oil, water, herbal extract. Zimadat is prepared just before application and used in many disease conditions as resolving, styptic, astringent, and antiseptic. As the pre-application procedure is difficult and also complicated for patients, hence, the present study attempted to modify the form of Zimad into cream. Various batches of cream of Zimad Mohallil were prepared by using extracts of the formulation and by adding additives. Various physicochemical parameters of prepared cream were carried and compared with market cream. The optimized cream of Zimad Mohallil (F 4 ) was selected after preliminary tests and evaluated further. The optimized cream showed good results in physicochemical parameters equivalent to market sample. Zimad Mohallil was converted into convenient cream form by adding minimum additives and benefits could be achieved without any hassle and cumbersome work, which is encountered in crude or paste form. The optimized cream was equivalent to standard market cream. Copyright © 2017 Transdisciplinary University, Bangalore and World Ayurveda Foundation. Published by Elsevier B.V. All rights reserved.

    Both experimental and clinical studies have shown a role for inflammation in the pathogenesis of heart failure. This seems related to an imbalance between pro-inflammatory and anti-inflammatory cytokines. Certain categories in patients with dilated cardiomyopathy have shown the presence of humoral and cellular immunity activation suggesting a possible relation between myocarditis and dilated cardiomyopathy. Recent studies suggest a link between the circulating levels of cytokines (TNF alpha IL-1 et IL-6), the clinical status and prognostic. However, the mechanisms connecting heart failure and cytokine activation are unclear and the sites of cytokines production remain controversial. In the clinical setting, specific measurements of cytokines are not available. As tests of inflammation, erythrocyte sedimentation rate and C-reactive protein concentration appear to have interesting pronostic values. Current conventional therapy i.e. ACE inhibitors, type I angiotensin II antagonist and beta-blockers have shown some anti-cytokine properties. Recently, immunosuppressive therapies have shown their ability to improve symptoms and LV ejection in selected patients with dilated cardiomyopathy and clear sign of myocardium inflammation. Specific anti-cytokine therapy have been developed and showed interesting results in preliminary clinical studies. However large clinical trials testing this new therapy have been stoppel prematurely because of deterious effects.

    Full Text Available Over-activated microglia is involved in various kinds of neurodegenerative process including Parkinson, Alzheimer and HIV dementia. Suppression of microglial over activation has emerged as a novel strategy for treatment of neuroinflammation-based neurodegeneration. In the current study, anti-inflammatory and neuroprotective effects of the ent-kauranoid diterpenoids, which were isolated from the aerial parts of Rabdosia japonica (Burm. f. var. glaucocalyx (Maxim. Hara, were investigated in cultured microglia cells. Glaucocalyxin B (GLB, one of five ent-kauranoid diterpenoids, significantly decreased the generation of nitric oxide (NO, tumor necrosis factor (TNF-α, interleukin (IL-1β, cyclooxygenase (COX-2 and inducible nitric oxide synthase (iNOS in the lipopolysaccharide (LPS-activated microglia cells. In addition, GLB inhibited activation of nuclear factor-κB (NF-κB, p38 mitogen-activated protein kinase (MAPK and generation of reactive oxygen species (ROS in LPS-activated microglia cells. Furthermore, GLB strongly induced the expression of heme oxygenase (HO-1 in BV-2 microglia cells. Finally, GLB exhibited neuroprotective effect by preventing over-activated microglia induced neurotoxicity in a microglia/neuron co-culture model. Taken together, the present study demonstrated that the GLB possesses anti-nueroinflammatory activity, and might serve as a potential therapeutic agent for treating neuroinflammatory diseases.

  12. Anti-inflammatory polymer electrodes for glial scar treatment

    2014-05-01

    Full Text Available Conducting polymer films offer a convenient route for the functionalization of implantable microelectrodes without compromising their performance as excellent recording units. A micron thick coating, deposited on the surface of a regular metallic electrode, can elute anti-inflammatory drugs for the treatment of glial scarring as well as growth factors for the support of surrounding neurons. Electroactivation of the polymer drives the release of the substance and should ideally provide a reliable method for controlling quantity and timing of release. Driving signals in the form of a constant potential, a slow redox sweep or a fast pulse are all represented in literature. Few studies present such release in vivo from actual recording and stimulating microelectronic devices. It is essential to bridge the gap between studies based on release in vitro, and the intended application, which would mean release into living and highly delicate tissue. In the biological setting, signals are limited both by available electronics and by the biological safety. Driving signals must not be harmful to tissue and also not activate the tissue in an uncontrolled manner. This review aims at shedding more light on how to select appropriate driving parameters for the polymer electrodes for the in vivo setting. It brings together information regarding activation thresholds for neurons, as well as injury thresholds, and puts this into context with what is known about efficient driving of release from conducting polymer films.

    2012-01-01

    The medicinal uses of saffron (Crocus sativus Linnaeus) have a long history beginning in Asian countries since the Late Bronze Age. Recent studies have validated its potential to lower the risk of several diseases. Some metabolites derived from saffron stigmas exert numerous therapeutic effects due to hypolipidemic, antitussive, antioxidant, antidiabetic activities and many others. Water and ethanol extracts of Crocus sativus L. are cardioprotective and counteract neurodegenerative disorders. Many of these medicinal properties of saffron can be attributed to a number of its compounds such as crocetin, crocins and other substances having strong antioxidant and radical scavenger properties against a variety of radical oxygen species and pro-inflammatory cytokines. Botany, worldwide spreading of cultivars, biochemical pathways, active constituents and chemical detection methods are reviewed. Therapeutic uses of saffron principles with particular regard to those exhibiting antioxidant and thus anti-inflammatory features are discussed. To date, very few adverse health effects of saffron have been demonstrated. At high doses (more than 5 g/die day), it should be avoided in pregnancy owing to its uterine stimulation activity.

    Polyphenols have been extensively investigated with regard to their antioxidant, anti-inflammatory, and immunomodulant properties in many inflammatory chronic conditions. The aim of this review is to summarise how these compounds can modulate the inflammatory pathways which characterise the most prevalent arthropathies including osteoarthritis, rheumatoid arthritis and crystal-induced arthritis. Among polyphenols, epigallocatechin gallate, carnosol, hydroxytyrosol, curcumin, resveratrol, kaempferol and genistein have been the most widely investigated in arthritis. The most important results of the studies outlined in this article show how polyphenolic compounds are able to inhibit the expression and the release of a number of pro-inflammatory mediators and proteolytic enzymes, the activity of different transcriptional factors and the production of reactive oxygen species in vitro. Studies on animal models of rheumatoid arthritis, osteoarthritis and gout show interesting results in terms of reduced tissue damage, restored cartilage homeostasis, and decreased levels of uric acid, respectively. Despite the multiple protective effects of polyphenols, there are no dietary recommendations for patients affected by rheumatic diseases. Future studies, including intervention trials, should be conducted to determine the relevance of polyphenols consumption or supplementation in arthritis. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

    In vivo and in vitro screening of anti inflammatory activity of Valeriana wallichii and Achyranthes aspera leaves crude extract was performed, using standardized procedures. Methanolic crude extract topical formulation (cream) of Valeriana wallichii and Achyranthes aspera leaves (Family Valerianaceae and Amaranthaceae respectively), were screened for their anti-inflammatory activity, through "Carrageenan induced hind paw edema" test, for their effect on the acute and chronic phase inflammation models in male Wistar rats. Methanolic extract and its fractions were also evaluated for their in vitro anti-inflammatory activity using lipoxygenase inhibition assay. Leaves of Valeriana wallichii showed significant (PValeriana wallichii also showed considerable (IC 50=73 ± 0.36) in vitro anti-inflammatory activity as compared to standard (6.11 ± 0.02). Similarly Achyranthes aspera leaves showed relatively weak (p>0.05) in vivo anti-inflammatory activity. However, its activity was comparable with that of standard at 10% concentration after 5 hrs of carrageenan injection. This activity was present in ethyl acetate fraction during in vitro screening (IC 50=76 ± 0.14) as compared to that of standard (IC 50=6.11 ± 0.02). The combined in vitro and in vivo Anti-inflammatory screening shows that the ethyl acetate fraction of the crude extract of Valeriana wallichii and Achyranthes aspera can be used for the isolation of new Anti-inflammatory lead compounds.

  17. Anti-inflammatory effects of phytochemicals from fruits, vegetables, and food legumes: A review.

    Zhu, Fengmei; Du, Bin; Xu, Baojun

    2017-06-12

    Inflammation is the first biological response of the immune system to infection, injury or irritation. Evidence suggests that the anti-inflammatory effect is mediated through the regulation of various inflammatory cytokines, such as nitric oxide, interleukins, tumor necrosis factor alpha-α, interferon gamma-γ as well as noncytokine mediator, prostaglandin E 2 . Fruits, vegetables, and food legumes contain high levels of phytochemicals that show anti-inflammatory effect, but their mechanisms of actions have not been completely identified. The aim of this paper was to summarize the recent investigations and findings regarding in vitro and animal model studies on the anti-inflammatory effects of fruits, vegetables, and food legumes. Specific cytokines released for specific type of physiological event might shed some light on the specific use of each source of phytochemicals that can benefit to counter the inflammatory response. As natural modulators of proinflammatory gene expressions, phytochemical from fruits, vegetables, and food legumes could be incorporated into novel bioactive anti-inflammatory formulations of various nutraceuticals and pharmaceuticals. Finally, these phytochemicals are discussed as the natural promotion strategy for the improvement of human health status. The phenolics and triterpenoids in fruits and vegetables showed higher anti-inflammatory activity than other compounds. In food legumes, lectins and peptides had anti-inflammatory activity in most cases. However, there are lack of human study data on the anti-inflammatory activity of phytochemicals from fruits, vegetables, and food legumes.

    Recent studies point at the anti-inflammatory action of silver through induction of apoptosis of inflammatory cells via oxidative stress, promotion of wound healing as well as antimicrobial effect. Our aim was to design a new formulation based on silver and validate its anti-inflammatory activity in the mouse models of colitis. Silver-coated glass beads were prepared using a magnetron sputtering method and a standard magnetron sputtering gun equipped with pure silver target. Colitis was induced by the ic administration of TNBS into colon (to mimic Crohn's disease) and addition of DSS to drinking water (to imitate ulcerative colitis). Evaluation of inflammation was performed based on macroscopic and microscopic scoring, quantification of the myeloperoxidase activity and colonic microflora analysis. Silver-coated glass beads administered ic alleviated intestinal inflammation in mouse models of colitis, induced by TNBS and DSS. This alleviation of colitis resulted principally from changes in the gut microflora. The anti-inflammatory action of the new formulation was associated predominantly with the presence of the silver nanolayer on the beads, and to a lesser extent the size of glass polymer units. The application of the newly developed formulation employing silver-coated glass beads has the potential to be translated to clinical conditions for the efficient treatment of IBD.

    In this paper we report the design, synthesis, antinociceptive and anti-inflammatory activities of a series of benzothiazine N-acylhydrazones 14a–h, planned by structural modification of piroxicam (1), a non steroidal anti-inflammatory drug. Among the synthesized analogues, compounds 14f (LASSBio-1637) and 14g (LASSBio-1639) were identified as novel antinociceptive and anti-inflammatory prototypes, active by oral administration, acting by a mechanism of action that seems to be different from that of piroxicam, since they were inactive as an inhibitor of cyclooxygenase (COX-1 and COX-2) at concentrations of 10 mM.

    Oral nonsteroidal anti-inflammatory drugs (NSAIDs) are widely used in the treatment of pain in fibromyalgia, despite being considered not to be effective. To assess the analgesic efficacy, tolerability (drop-out due to adverse events), and safety (serious adverse events) of oral nonsteroidal anti-inflammatory drugs for fibromyalgia in adults. We searched CENTRAL, MEDLINE, and Embase for randomised controlled trials from inception to January 2017. We also searched the reference lists of retrieved studies and reviews, and online clinical trial registries. We included randomised, double-blind trials of two weeks' duration or longer, comparing any oral NSAID with placebo or another active treatment for relief of pain in fibromyalgia, with subjective pain assessment by the participant. Two review authors independently extracted data and assessed trial quality and potential bias. Primary outcomes were participants with substantial pain relief (at least 50% pain relief over baseline or very much improved on Patient Global Impression of Change scale (PGIC)) or moderate pain relief (at least 30% pain relief over baseline or much or very much improved on PGIC), serious adverse events, and withdrawals due to adverse events; secondary outcomes were adverse events, withdrawals due to lack of efficacy, and outcomes relating to sleep, fatigue, and quality of life. Where pooled analysis was possible, we used dichotomous data to calculate risk difference (RD) and number needed to treat for an additional beneficial outcome (NNT), using standard methods. We assessed the quality of the evidence using GRADE and created a 'Summary of findings' table. Our searches identified six randomised, double-blind studies involving 292 participants in suitably characterised fibromyalgia. The mean age of participants was between 39 and 50 years, and 89% to 100% were women. The initial pain intensity was around 7/10 on a 0 to 10 pain scale, indicating severe pain. NSAIDs tested were etoricoxib 90 mg

    Full Text Available Aim. The aim of this study was to assess serum levels of the key anti-inflammatory cytokines in women of reproductive age and in pre and postmenopausal women. Material and Method. 175 women were enrolled and were divided into 5 groups (1 – Fertile women; 2 – Pre- and perimenopausal women; 3 – Postmenopausal women; 4 – Surgically-induced menopause; 5 – Chronic inflammation. Multiplex cytokine kits were used to evaluate serum levels of interleukin-4, -10 and -13. We determined the serum levels of follicle stimulating hormone, of luteinizing hormone, 17β-estradiol, progesterone, dehydroepiandrosterone and dehydroepiandrosterone sulfate using sandwich ELISA. Results. IL-4, IL-10 and IL-17 present a statistically significant decrease (p=0.00, p=0.00, respectively p=0.0053 in women with natural or surgically induced menopause (groups 3 and 4, compared with fertile women and premenopausal women (Groups 1, 2 and 5. Serum levels of IL-4 and IL-10 are significantly higher in fertile patients with associated chronic inflammatory diseases (133.5±1.314 pg/ml, respectively 6.406±13.47 pg/ml than in fertile patients without chronic inflammatory diseases or premenopausal women (84.67±1.22 pg/ml, respectively 0.627±0.714. Conclusions. IL-4 and IL-10, together with IL-17, show significantly lower serum values in patients with natural or surgically induced menopause compared with patients of childbearing age or in premenopause. IL-4 and IL-10 show significantly higher serum values for patients of childbearing age presenting chronic inflammatory pathology compared with patients of childbearing age without chronic inflammatory pathology or premenopausal patients.

    Full Text Available Soybean agglutinin (SBA lectin, a protein present in raw soybean meals, can bind to and be extensively endocytosed by intestinal epithelial cells, being nutritionally toxic for most animals. In the present study we show that SBA (5-200 µg/cavity injected into different cavities of rats induced a typical inflammatory response characterized by dose-dependent exudation and neutrophil migration 4 h after injection. This effect was blocked by pretreatment with glucocorticoid (0.5 mg/kg or by co-injection of N-acetyl-galactosamine (100 x [M] lectin, but not of other sugars (100 x [M] lectin, suggesting an inflammatory response related to the lectin activity. Neutrophil accumulation was not dependent on a direct effect of SBA on the macrophage population since the effect was not altered when the number of peritoneal cells was increased or decreased in vivo. On the other hand, SBA showed chemotactic activity for human neutrophils in vitro. A slight increase in mononuclear cells was observed 48 h after ip injection of SBA. Phenotypic analysis of these cells showed an increase in the CD4+/CD8- lymphocyte population that returned to control levels after 15 days, suggesting the development of an immune response. SBA-stimulated macrophages presented an increase in the expression of CD11/CD18 surface molecules and showed some characteristics of activated cells. After intravenous administration, SBA increased the number of circulating neutrophils and inhibited in a dose-dependent manner the neutrophil migration induced by ip injection of carrageenan into peritoneal cavities. The co-injection of N-acetyl-galactosamine or mannose, but not glucose or fucose, inhibited these effects. The data indicate that soybean lectin is able to induce a local inflammatory reaction but has an anti-inflammatory effect when present in circulating blood

    Inflammatory disorders result from continuous inflammation in injured sites. Many molecules are involved in this process; the inhibition of which could prevent the inflammation. Chemokines are a group of these biological mediators which are categorized into pro-, anti-, and pro-/anti-inflammatory. Thus, targeting these essential molecules can be an effective way for prevention and control of inflammatory diseases. Various therapeutic agents have been developed for primary and secondary prevention of these disorders, but each of them has its own limitations. Aptamers, as novel therapeutic agents, are a new generation of drugs which could replace other medications even antibodies. Aptamer can bind to its target molecule to trap it and prohibit its function. Among large group of inflammatory cytokines, only 11 aptamers have been selected either against cytokines or their related receptors. These cytokines include interleukin (IL)-2, IL-6, IL-10, IL-11, IL-17, IL-32, TGF-β, TNF-α, IFN-γ, CCL2, and IP-10. Most of the isolated aptamers are against pro-inflammatory or dual function cytokines, and it seems that they could be used for diagnosis, prevention, and treatment of the related inflammatory diseases. Most of the aptamers have been tested in vitro, but so far, none of them has been approved for in vivo use. Given a vast number of inflammatory cytokines, more aptamers against this group of biological molecules will be selected in the near future. The available aptamers will also be tested in clinical trials. Therefore, a significant improvement is expected for the prevention and control of inflammatory disorders.

    Full Text Available Plant essential oils are plant secondary metabolites possessing various pharmacological properties, primarily anti-oxidative, antimicrobial or immunomodulatory ones. The aim of this work was to study the effects of thyme essential oil dietary administration in murine DTH/ CHS reaction, carrageenan paw oedema and TNBS colitis. Thyme essential oil was added to the murine diet at three concentrations (5000, 2500 and 1250 ppm and fed to Balb/c mice. The extent of ear swelling in DTH/CHS reaction and paw oedema induced by carrageenan application was measured using the Mitutoyo thickness gauge. In the model of TNBS colitis we evaluated the changes in body weight, the colon weight : body weight ratio, bacterial translocation to mesenteric lymph nodes, and macroscopical and histological scores. IL-1β and IL-6 messenger RNA expression in colonic samples of one experimental group were assessed using quantitative real-time reverse transcriptase PCR. Dietary supplementation with 5000 ppm of thyme essential oil significantly decreased paw oedema and ear swelling. This thyme essential oil concentration caused a significant inhibition of total mRNA IL-1β expression in the mouse colon, and markedly decreased the macroscopic and microscopic scores of colitis. On the other hand, the 1250 ppm of thyme essential oil in diet increased ear oedema induced by oxazolone application in mice. Our study indicates that thyme essential oil is able to affect murine experimental inflammatory models depending on the concentration used. It is concluded that the anti-inflammatory effects of thyme essential oil should be interpreted with a caution due to its contradictory, dose-related effects.

    Full Text Available Background and objectives: Paricalcitol, a selective vitamin D receptor activator, is used to treat secondary hyperparathyroidism in kidney transplant patients. Experimental and clinical studies in non-transplant kidney disease patients have found this molecule to have anti-inflammatory properties. In this exploratory study, we evaluated the anti-inflammatory profile of paricalcitol in kidney-transplant recipients. Methods: Thirty one kidney transplant recipients with secondary hyperparathyroidism completed 3 months of treatment with oral paricalcitol (1 μg/day. Serum concentrations and gene expression levels of inflammatory cytokines in peripheral blood mononuclear cells were analysed at the beginning and end of the study. Results: Paricalcitol significantly decreased parathyroid hormone levels with no changes in calcium and phosphorous. It also reduced serum concentrations of interleukin (IL-6 and tumour necrosis factor-alpha (TNF-α by 29% (p < 0.05 and 9.5% (p < 0.05 compared to baseline, respectively. Furthermore, gene expression levels of IL-6 and TNF-α in peripheral blood mononuclear cells decreased by 14.1% (p < 0.001 and 34.1% (p < 0.001, respectively. The ratios between pro-inflammatory cytokines (TNF-α and IL-6 and anti-inflammatory cytokines (IL-10, both regarding serum concentrations and gene expression, also experienced a significant reduction. Conclusions: Paricalcitol administration to kidney transplant recipients has been found to have beneficial effects on inflammation, which may be associated with potential clinical benefits. Resumen: Antecedentes y objetivos: El paricalcitol, un activador selectivo del receptor de la vitamina D, se utiliza en el tratamiento del hiperparatiroidismo secundario en el receptor de trasplante renal.

    The inhibition of gastric cyclooxygenase 1 (COX-1) enzyme was believed to be the major cause of non-steroidal anti-inflammatory drugs (NSAIDs)-induced gastric ulcer. Recent studies disproved this belief and showed that the gastric tissues vulnerability is not solely connected to COX-1 inhibition. This work aimed at exploring and rationalizing the differential analgesic and anti-inflammatory activities of novel selective COX-1 inhibitors with improved gastric profile. Two novel series of 4,5-diarylthiazole and diarylimidazole were designed, synthesized in analogy to selective COX-1 inhibitors (mofezolac and FR122047) which lack gastric damaging effects. The new compounds were evaluated in vitro for their COXs inhibitory activity and in vivo for their anti-inflammatory and analgesic potentials. Four compounds; diphenylthiazole glycine derivatives (15a, 15b) and diphenylimidazolo acetic acid derivatives (19a, 19b), which possess carboxylic acid group exhibited significant activity and selectivity against COX-1 over COX-2. Of these compounds, (4,5-bis(4-methoxyphenyl)thiazol-2-yl)glycine 15b was the most potent compound against COX-1 with an inhibitory half maximal concentration (IC 50 ) of 0.32μM and a selectivity index (COX-2 IC 50 /COX-1 IC 50 ) of 28.84. Furthermore, an ulcerogenicity study was performed where the tested compounds demonstrated a significant gastric tolerance. Interestingly, the most selective COX-1 inhibitor showed higher analgesic activity in vivo as expected compared to their moderate anti-inflammatory activity. This study underscores the need for further design and development of novel analgesic agents with low tendency to cause gastric damage based on improving their COX-1 affinity and selectivity profile.

    Full Text Available Ankylosing spondylitis (AS is a chronic systemic disease with predominant axial skeleton injury, peripheral articular and entheseal involvements, and extra-skeletal manifestations. 8–10 years elapse since the first manifestations of AC to its diagnosis, leading to delays in adequate therapy, to the progression of structural and functional impairments in the axial skeleton and peripheral joints and to the development of complications. According to the international and Russia's Association of Rheumatologists guidelines, nonsteroidal anti-inflammatory drugs (NSAIDs are an important component of AS therapy. It is necessary to carefully choose the safest NSAID for these patients, by taking into consideration that AS therapy should be long-term and continuous.The trial previously performed by the authors evaluated comorbidity in 220 AS patients long receiving nimesulide. Its long-term administration was shown to cause no increase in the level of liver enzymes. Esophagogastroduodenoscopy revealed antral gastritis in 23.6% of the patients, gastric mucosal erosions in 13, and gastric ulcer disease without an exacerbation in 3.6%. It was noted that the physicians had not prescribed gastroprotectors to the patients. Nimesulide caused no blood pressure (BP elevation even in patients who had baseline hypertension. Elevated BP occurred in 2.5% of the patients. There was no clear association of higher BP with nimesulide intake since the patients had previously used other NSAIDs, mainly diclofenac, to treat severe pain syndrome. These findings suggest that in addition to its analgesic activity, nimesulide shows good tolerability in patients with AS, which permits its long-term use, but in this case the gastrointestinal tract and BD should be carefully monitored, which will be able to prevent the possible adverse events characteristic of the entire group of NSAIDs.

    Full Text Available Background: There is no cure for autoimmune chronic inflammatory bowel disease (IBD. IBD patients commonly use complementary and alternative medications of which the safety, efficacy and interaction with standard-of-care therapies are not fully known. Thus the consequences can become life-threatening. Sulfasalazine commonly used in IBD, potentially has severe adverse effects, including infertility, pulmonary fibrosis, lack of response and ultimately patients may require intestinal resection. We hypothesized that green tea polyphenols (GrTP, EGCG and sulfasalazine have similar anti-inflammatory properties. Methods: BALB/c mice received Dextran sodium sulfate (DSS to induce colitis (ulcerative colitis model. Exposure of IL-10 deficient mice (BALB/c-background to normal microbiota provoked enterocolitis (mimics Crohn’s disease. Animals were treated with agents incorporated into daily diets. Control animals received sham treatment. Results: DSS-treated animals developed severe bloody diarrhea and colitis (score 0-4, 3.2+0.27. IL-10 deficient mice developed severe enterocolitis as manifested by diarrhea, rectal prolapse and colonic lesions. Animals tolerated regimens (GrTP, EGCG, sulfasalazine with no major side effects, and further developed less severe colitis/enterocolitis. GrTP, EGCG and sulfasalazine significantly ameliorated colonic damage and histological scores in treated animals in a similar manner (GrTP vs DSS p<0.05; EGCG, sulfasalazine vs DSS p<0.01. The inflammatory markers TNFα (3-fold, IL-6 (14-fold and serum amyloid A (40-fold increased in colitic animals and significantly decreased with treatment regiments. In contrast, circulatory leptin levels decreased in colitic animals (2-fold. EGCG additionally reduced leptin levels (p<0.01 while GrTP and sulfasalazine had no effect on leptin levels (p<0.05. Hepatic and colonic antioxidants were significantly depleted in colitic animals and treatment regiments significantly restored

    Nonsteroidal anti-inflammatory drugs (NSAIDs) are the cornerstone of pain management. There are no detailed data on NSAIDs use in Poland, especially in patients with chronic kidney disease (CKD). The aim of this study was to evaluate the frequency, circumstances, and causes of NSAIDs use as well as knowledge of their side-effects in patients with CKD. This cross-sectional study was conducted in 972 individuals with CKD, enrolled in a written survey originally developed by the authors. There were 574 patients with CKD stage I-IV, 414 patients after renal transplantation stage II-IV (CKDT) and 84 dialyzed patients (44 peritoneal, 40 hemodialysis). Among the entire study group, 16.9 % of patients used NSAIDs every day, or several times a week. The average number of tablets taken within a month was 21.8. Subgroup analysis revealed that NSAIDs were taken most often by patients on hemodialysis: 35 % of them used NSAIDs every day or several times a week (43.15 pills per month). The most common reason for using NSAIDs were bone-joint pain (29.3 %) and headache (26.2 %). Side effects of painkillers such as renal function deterioration and the possible promotion of stomach ulcers were experienced by 43.6 and 37.6 % of respondents, respectively. Patients with CKD often take NSAIDs. This applies especially to the group of people undergoing hemodialysis, which is mainly associated with chronic osteo-articular pain. The results also show a low awareness of painkillers' adverse effects.

    Methanolic extracts of 13 seaweeds collected from the Mediterranean sea (Tunisian, Moroccan and Greek coasts) from different classes (Chlorophycae, Pheopbycae and Rhodophycae) are testedfor their analgesic and antiinflammatory effects. These activities were estimated in vivo, respectively by writhing test and carrageenan test. Nine species among 13 tested seaweeds showed an important analgesic activity. On the other hand only 5 seaweeds showed a significant anti-inflammatory activity (Cystoseira barbata and Sargassum vulgare) had endowed with the double analgesic and anti-inflammatory activity. The red algae Geliduim sesquipedale have only anti-inflammatory activity and the other one endowed only with an analgesic activity (Enteromorpha compressa, Chaetomorpha linum, Cystoseira ericoidies, Sacchoriza bulbosa et Corralina officinalis). The simultaneous or individual presence of the analgesic and\\or anti-inflammatory activities of the various extracts can find its application in the therapeutic domain.

    Probiotics have been shown to improve the condition of not only the human gastrointestinal tract but also the entire body. We found that quercetin enhances the anti-inflammatory activity of Bifidobacterium adolescentis, which is abundant in human intestines. Here, we assessed whether certain phytochemicals could enhance the anti-inflammatory activity of B. adolescentis. Bifidobacteria were anaerobically cultured with phytochemicals for 3 h, and the anti-inflammatory activity of the supernatants was estimated by testing their ability to inhibit nitric oxide (NO) production by lipopolysaccharide-stimulated RAW264 macrophages. Of the 55 phytochemicals tested, phloretin, (+)-taxifolin, and (-)-epigallocatechin gallate as well as quercetin-3-O-glucoside and quercetin-4'-O-glucoside were similar to quercetin in promoting NO suppression by B. adolescentis. In addition, the phytochemicals excluding quercetin increased the concentrations of lactic and acetic acids in the co-culture supernatants. These results suggest that some phytochemicals may activate the anti-inflammatory function of B. adolescentis.

    Byrsonima crassifolia is a tropical tree, commonly known as nance and distributed widely in Mexico and Central and South America. Since pre- Hispanic times, the seeds of the fruits have been used in folklore medicine as an anti-inflammatory; however, currently no researchers have examined its potential pharmacological properties in scientific studies. This study investigated the anti-inflammatory activity of extracts obtained with the solvents n-hexane, chloroform, and methanol from seeds of B crassifolia. The research team induced edemas in Wistar rats with 12-O-tetradecanoylphorbol (TPA), formaldehyde, carrageenan, and histamine to study the anti-inflammatory activity of the three organic extracts of seeds from B crassifolia. The team also used the cotton-pellet granuloma method to induce edemas in Wistar rats and study the inhibitory effect of the three extracts from B crassifolia. Finally, the team examined the participation of the nitric oxide (NO) system in the anti-inflammatory activity of the hexane extract of nance seeds (NS), diclorofenac, and L-NAME as well as the effects of L-arginine and D-arginine on the antiinflammatory actions of the compounds. This research was conducted in the Laboratory of Research of Natural Products, School of Chemical Engineering, National Polytechnic Institute (IPNESIQIE) and Department of Biotechnology and Bioengineering, Cinvestav-IPN, Av. IPN 2508, Col. San Pedro Zacatenco, Mexico D.F., CP 07360, Mexico. The research team measured the edema that the solvents caused, either in the ears of rats for tetradecanoylphorbol or in the paws for formaldehyde, carrageenan, and histamine. To study the antiproliferative effects of the extracts after implantation of the cotton-pellet granuloma, the team determined the wet and dry weights of the pellets, after drying at 70°C for 1 hour in the second case. To study the participation of the NO system in the anti-inflammatory activity of the hexane extract of NS, diclofenac, and L

    Acute angioedema represents a cause of admission to the emergency department requiring rapid diagnosis and appropriate management to prevent airway obstruction. Several drugs, including angiotensin-converting enzyme inhibitors (ACE-I), nonsteroidal anti-inflammatory drugs (NSAIDs) and oral antidiabetics, have been reported to induce angioedema. The aim of this prospective observational study conducted in a setting of routine emergency care was to evaluate the incidence and extent of drug-induced non-histaminergic angioedema in this specific clinical setting, and to identify the class of drugs possibly associated with angioedema. Patients admitted to seven different emergency departments (EDs) in Rome with the diagnosis of angioedema and urticaria were enrolled during a 6-month period. Of the 120,000 patients admitted at the EDs, 447 (0.37 %) were coded as having angioedema and 655 (0.5 %) as having urticaria. After accurate clinical review, 62 cases were defined as drug-induced, non-histaminergic angioedema. NSAIDs were the most frequent drugs (taken by 22 out of 62 patients) associated with the angioedema attack. Of the remaining patients, 15 received antibiotic treatment and 10 antihypertensive treatment. In addition, we observed in our series some cases of angioedema associated with drugs (such as antiasthmatics, antidiarrheal and antiepileptics) of which there are few descriptions in the literature. The present data, which add much needed information to the existing limited literature on drug-induced angioedema in the clinical emergency department setting, will provide more appropriate diagnosis and management of this potentially life-threatening adverse event.

    Current antiepileptic drugs have limited efficacy and provide little or no benefits in 30% of the patients. Given that a role for brain inflammation in epilepsy has been repeatedly reported in recent years, the potential of anti-inflammatory drugs should be explored in depth, as they may provide new therapeutical approaches in preventing or reducing epileptogenesis. Here, we review preclinical (both in vivo and in vitro) and clinical epilepsy studies in which nonsteroidal antiinflammatory drugs (NSAIDs), i.e. cyclooxygenase-2 (COX-2) selective inhibitors (COXIBs) and nonselective NSAIDs, were used for seizure control. The effects of NSAIDs are reviewed in animal models of both chemical (pilocarpine, kainic acid, pentylenetetrazol, or carbachol administration) and electrical (tetanic hippocampal stimulation, electroshock) seizure induction. In the pilocarpine model, NSAIDs are neuroprotective, reduce mossy fiber sprouting or diminish P-glycoprotein upregulation, but only rarely protect against seizures. While neuroprotective effects have also been observed in the kainic acid model, NSAIDs tend in general to worsen seizure activity. Effects of COXIB administration in the pentylenetetrazol-induced seizures model are variable, alternating from protection against seizures to null effects or even increased incidence of convulsions. Moreover, NSAIDs tested in the tetanic hippocampal stimulation model diminished the seizure-associated P-glycoprotein upregulation, but were not very effective in seizure control. NSAIDs efficacy in experimental in vivo epilepsy studies may be influenced by multiple factors, including the timing of administration (before or after status epilepticus induction), the animal model of epilepsy or some of the signaling pathways involved in cyclooxygenase induction (e.g. prostaglandins and their receptors). On the other hand, the few clinical studies on the use of NSAIDs in neurological pathologies accompanied/characterized by seizures indicate that

    Nonsteroidal anti-inflammatory drugs (NSAIDs) are widely used for the relief of the symptoms of osteoarthritis (OA), rheumatoid arthritis (RA), sprains and strains, sports injuries and menstrual disorders, and have a small role in the management of patent ductus arteriosus in the neonate. In patients with RA, symptom relief through use of NSAIDs is firmly established, although it remains unclear whether they influence the course and outcome of the disease. For the average patient with RA taking NSAIDs, the attributable risk of hospitalisation with gastrointestinal problems related to NSAIDs is 1.3 to 1.6% annually and risk of death is 0.15%. Associations of therapy with risk are greatest with age, corticosteroid use and previous NSAID-related gastrointestinal adverse effects, and less marked with disability and high NSAID dose. These are important data in attempting to balance risk of therapy with clinical efficacy in an individual patient, and assessing the cost-effectiveness of prophylaxis. Although half of all NSAID consumption is for control of pain associated with degenerative conditions, their superiority over simple analgesics in osteoarthritis is poorly documented. This finding supports the use of the simple analgesic paracetamol (acetaminophen) as the preferred therapy of osteoarthritis, especially when its lower cost and low incidence of adverse effects are taken into consideration. Consistent differences in clinical effectiveness of individual NSAIDs have not been demonstrated, although unpredictable interpatient variation in response to individual agents is of considerable clinical importance, and a more expensive NSAID may prove cost effective for some patients. Cost effectiveness can be improved by a self-adjusted dosage regime which also leads to lower overall drug consumption. The adverse gastrointestinal effects of these drugs account for about 30% of the overall cost of arthritis treatment, and although studies to date have been too limited to

    Full Text Available Many biological properties have been attributed to various types of propolis, including anti-inflammatory, antimicrobial, antioxidant, antitumor, wound healing, and immunomodulatory activities. This article reviewed studies published that investigated the anti-inflammatory activity of propolis of different origins and/or its isolated components, focusing on the mechanisms of action underlying this activity and also addressing some aspects of immunomodulatory effects. The search was performed of the following databases: PubMed, Science Direct, HighWire Press, Scielo, Google Academics, Research Gate and ISI Web of Knowledgement. The anti-inflammatory activity was associated with propolis or compounds such as polyphenols (flavonoids, phenolic acids and their esters, terpenoids, steroids and amino acids. CAPE is the most studied compounds. The main mechanisms underlying the anti-inflammatory activity of propolis included the inhibition of cyclooxygenase and consequent inhibition of prostaglandin biosynthesis, free radical scavenging, inhibition of nitric oxide synthesis, reduction in the concentration of inflammatory cytokines and immunosuppressive activity. Propolis was found to exert an anti-inflammatory activity in vivo and in vitro models of acute and chronic inflammation and others studies, indicating its promising potential as anti-inflammatory agent of natural origin and as a source of chemical compounds for the development of new drugs.

    Non-steroidal anti-inflammatory drugs (NSAIDs) are worldwide used drugs for analgesic, antipyretic, and anti-inflammatory therapeutics. However, NSAIDs often cause several serious liver injuries, such as drug-induced liver injury (DILI), and the molecular mechanisms of DILI have not been clearly elucidated. In this study, we developed a systems pharmacology approach to explore the mechanism-of-action of NSAIDs. We found that the Farnesoid X Receptor (FXR) antagonism of NSAIDs is a potential molecular mechanism of DILI through systematic network analysis and in vitro assays. Specially, the quantitative real-time PCR assay reveals that indomethacin and ibuprofen regulate FXR downstream target gene expression in HepG2 cells. Furthermore, the western blot shows that FXR antagonism by indomethacin induces the phosphorylation of STAT3 (signal transducer and activator of transcription 3), promotes the activation of caspase9, and finally causes DILI. In summary, our systems pharmacology approach provided novel insights into molecular mechanisms of DILI for NSAIDs, which may propel the ways toward the design of novel anti-inflammatory pharmacotherapeutics.

    Full Text Available Drug-induced acute necrotizing pancreatitis is a rare adverse event, although it has been reported in association with different drugs, including non-steroidal anti-inflammatory drugs, disease-modifying antirheumatic drugs, and analgesic agents commonly used in rheumatology. In different reviews of the pancreotoxicity of drugs, infliximab and etanercept are mentioned among all medications implicated in drug-induced pancreatitis, but clinical cases of acute pancreatitis complicating treatment with these anti-TNF-α agents have been exceptionally reported. We describe a patient with ankylosing spondylitis treated with etanercept, who developed an acute fulminant necrotizing pancreatitis that resulted in death. Doctors should pay close attention to patients taking biologic drugs in which a complaint of abdominal pain lasting for several days with no apparent cause may require a prompt referral for medical consultation.

    Pomegranate (Punica granatum L.; Lythraceae) has traditionally been used for the treatment of various inflammatory diseases, including ulcerative colitis (UC). Because its fruits and extracts are rich in ellagitannins, which release ellagic acid when hydrolyzed, consumption of pomegranate products is currently being widely promoted for their potential health effects, including the prevention of inflammatory diseases and cancer. To evaluate the anti-inflammatory effects of ellagic acid on dextran sulfate sodium (DSS)-induced acute and chronic experimental colitis in two different strains of mice and to elucidate its possible mechanisms of action. In the acute UC model, female Balb/C mice were treated with DSS (5%) for seven days while concomitantly receiving a dietary supplement of ellagic acid (2%). In the chronic UC model, female C57BL/6 mice received four week-long cycles of DSS (1% and 2%) interspersed with week-long recovery periods along with a diet supplemented with ellagic acid (0.5%). In acute model of UC, ellagic acid ameliorated disease severity slightly as observed both macroscopically and through the profile of inflammatory mediators (IL-6, TNF-α, and IFN-γ). In the chronic UC model, ellagic acid significantly inhibited the progression of the disease, reducing intestinal inflammation and decreasing histological scores. Moreover, mediators such as COX-2 and iNOS were downregulated and the signaling pathways p38 MAPK, NF-κB, and STAT3 were blocked. Our study reinforces the hypothetical use of ellagic acid as an anti-inflammatory complement to conventional UC treatment in chronic UC patients and could be considered in the dietary prevention of intestinal inflammation and related cancer development. © 2013 Published by Elsevier Ireland Ltd.

  6. Approaches to the diagnosis and management of patients with a history of nonsteroidal anti-inflammatory drug-related urticaria and angioedema.

    Nonsteroidal anti-inflammatory drug (NSAID)-induced urticarial and angioedema reactions are among the most commonly encountered drug hypersensitivity reactions in clinical practice. Three major clinical phenotypes of NSAID-induced acute skin reactions manifesting with angioedema, urticaria, or both have been distinguished: NSAID-exacerbated cutaneous disease, nonsteroidal anti-inflammatory drug-induced urticaria/angioedema (NIUA), and single NSAID-induced urticaria and angioedema. In some patients clinical history alone might be sufficient to establish the diagnosis of a specific type of NSAID hypersensitivity, whereas in other cases oral provocation challenges are necessary to confirm the diagnosis. Moreover, classification of the type of cutaneous reaction is critical for proper management. For example, in patients with single NSAID-induced reactions, chemically nonrelated COX-1 inhibitors can be safely used. However, there is cross-reactivity between the NSAIDs in patients with NSAID-exacerbated cutaneous disease and NIUA, and thus only use of selective COX-2 inhibitors can replace the culprit drug if the chronic treatment is necessary, although aspirin desensitization will allow for chronic treatment with NSAIDs in some patients with NIUA. In this review we present a practical clinical approach to the patient with NSAID-induced urticaria and angioedema. Copyright © 2015 American Academy of Allergy, Asthma & Immunology.

    2017-04-19

    Abomasal ulcers lead to several problems. They cause pain resulting in a decrease in productivity and even the possible loss of the animal. Because they are frequently difficult to diagnose, information on their prevalence is variable. Additionally, therapeutic options are limited. Abomasal ulcers are graded as type 1 through 4, type 1 being a superficial defect and type 2 an ulcer where a large blood vessel has been eroded, leading to substantial blood loss. Types 3 and 4 are perforated abomasal ulcers leading to local and diffuse peritonitis, respectively. Causes of abomasal ulcers are multifactorial, for example, mistakes in feeding that lead to gastrointestinal disturbances or other diseases that induce stress. Ulcers can also result from side effects of nonsteroidal anti-inflammatory drugs. In principal, the pathophysiological cause is the disturbance of the balance between protective and aggressive mechanisms at the abomasal mucosa due to stress. Clinical symptoms vary and are mostly non-specific. Fecal occult blood tests, hematology and blood chemistry as well as ultrasonographic examination and abdominocentesis can help to establish the diagnosis. Ulcers can be treated symptomatically, surgically and medically. To prevent abomasal ulcers, animals should be kept healthy by providing adequate nutrition and housing as well as early and effective medical care. Stressful management practices, including transport and commingling, should be avoided.

    Novel antioxidant and anti-inflammatory peptides were isolated from hydrolysates of Siamese crocodile (Crocodylus siamensis) hemoglobin. C. siamensis hemoglobin hydrolysates (CHHs) were obtained by pepsin digestion at different incubation times (2, 4, 6, and 8 H) at 37 °C and subjected to antioxidant and anti-inflammatory activity assessment. CHH obtained by 2-H hydrolysis (2H-CHH) showed the highest anti-inflammatory activity with respect to decreasing nitric oxide (NO) production, whereas the strongest antioxidant activity was found for 6-H hydrolysis (6H-CHH) against nitric oxide radicals. To evaluate the anti-inflammatory and antioxidant activity of individual peptide components, 2H-CHH and 6H-CHH were purified by semipreparative HPLC. Peptide fraction P57 isolated from 6H-CHH was found to exhibit the highest nitric oxide radical inhibition activity (32.0%). Moreover, purification of 2H-CHH yielded peptide fraction P16, which displayed a high efficacy in decreasing NO production of macrophage RAW 264.7 cells (83.2%) and significantly reduced proinflammatory cytokines and inflammatory mediators interleukin-6 (IL-6), interleukin-1 beta (IL-1β), and prostaglandin-E2 (PGE 2 ) production to about 2.0, 0.3, and 1.9 ng/mL, respectively. Using LTQ orbitrap XL mass spectrometry, active peptide sequences were identified as antioxidant KIYFPHF (KF7), anti-inflammatory SAFNPHEKQ (SQ9), and IIHNEKVQAHGKKVL (IL15). Additionally, CHHs simulated gastric and intestinal in vitro digestion positively contributed to antioxidant and anti-inflammatory activity. Taken collectively, the results of this work demonstrate that CHHs contain several peptides with anti-inflammatory and antioxidant properties, which may prove valuable as treatment or supplement against diseases associated with inflammation and oxidative stress. © 2017 International Union of Biochemistry and Molecular Biology, Inc.

  12. Medical Management of Ulcerative Colitis with a Specific Focus on 5-Aminosalicylates

    Directory of Open Access Journals (Sweden)

    Hugh James Freeman

    2012-01-01

    Full Text Available Medical management of ulcerative colitis has continued to evolve over more than half of a century. Perhaps, the important advance was the development of sulfasalazine, a drug initially used for the treatment of inflammatory joint disease and only later in the treatment of inflammatory bowel disease. Sulfasalazine was a combination designer drug consisting of sulfapyridine, a sulfa-containing antibacterial agent, and 5-amino-salicylate (5-ASA, an anti-inflammatory agent. Its value appeared to be its ability to target a therapeutic concentration of the 5-ASA component of the medication primarily in the colon, largely avoiding proximal small intestinal absorption. With increasing experience, however, it also became evident that many patients treated with sulfasalazine developed intolerance to the drug and, in some rare instances, serious drug-induced hypersensitivity reactions, largely to the sulfapyridine portion. As a result, a number of alternative forms of delivery of 5-ASA were developed consisting of either a similar sulfasalazine-like prodrug formulation requiring luminal destruction of an azo-bond releasing the 5-ASA or a pH-dependent 5-ASA packaging system that permitted release in the distal intestine, particularly in the colon. As a result, 5-ASA—containing medications continue to provide a valuable management tool for remission induction in mildly to moderately active distal or extensive ulcerative colitis, an additional option for more severely symptomatic disease and value for maintenance therapy with limited potential side effects, even with long-term use.

    Medical management of ulcerative colitis has continued to evolve over more than half of a century. Perhaps, the important advance was the development of sulfasalazine, a drug initially used for the treatment of inflammatory joint disease and only later in the treatment of inflammatory bowel disease. Sulfasalazine was a combination designer drug consisting of sulfapyridine, a sulfa-containing antibacterial agent, and 5-amino-salicylate (5-ASA), an anti-inflammatory agent. Its value appeared to be its ability to target a therapeutic concentration of the 5-ASA component of the medication primarily in the colon, largely avoiding proximal small intestinal absorption. With increasing experience, however, it also became evident that many patients treated with sulfasalazine developed intolerance to the drug and, in some rare instances, serious drug-induced hypersensitivity reactions, largely to the sulfapyridine portion. As a result, a number of alternative forms of delivery of 5-ASA were developed consisting of either a similar sulfasalazine-like prodrug formulation requiring luminal destruction of an azo-bond releasing the 5-ASA or a pH-dependent 5-ASA packaging system that permitted release in the distal intestine, particularly in the colon.

    This review focuses on traditional and contemporary anti-inflammatory uses of mollusc-derived products summarising all the in vitro, in vivo and human clinical trials that have tested the anti-inflammatory activity of molluscan natural products. Inflammatory conditions, burns and wounds have been an ongoing concern for human health since the early era of civilisation. Many texts from ancient medicine have recorded the symptoms, signs and treatments for these conditions. Natural treatments are well-documented in traditional European medicine, Traditional Chinese Medicine (TCM), Siddha and ancient Mediterranean and African traditional medicine and include a surprisingly large number of molluscan species. An extensive review of the Materia Medica and scientific literature was undertaken using key word searches for "mollusc" and "anti-inflammatory" or "immunomodulatory" or "wound healing". Molluscs have been used in ethnomedicine by many traditional cultures to treat different aspects of inflammatory conditions. We found 104 different anti-inflammatory preparations from a variety of molluscan species, of which 70 were from the well-documented Traditional Chinese Medicine (TCM). This traditional use of molluscs has driven the testing for inflammatory activity in extracts from some species in the phylum Mollusca, with 20 in vitro studies, 40 in vivo animal studies and 14 human clinical trials performed to substantiate the anti-inflammatory and wound healing activity of molluscs. Some of these studies have led to the approval of mollusc-derived products to be used as over-the-counter (OTC) nutraceuticals, like Lyprinol® and Biolane™ from the New Zealand green lipped mussel Perna canaliculus. Natural products provide important leads for the development of pharmaceuticals, including anti-inflammatory agents. Only a small proportion of the molluscan traditional medicines have been tested to confirm their anti-inflammatory activity and most screening studies have tested

    Citrus fruits have potential health-promoting properties and their essential oils have long been used in several applications. Due to biological effects described to some citrus species in this study our objectives were to analyze and compare the phytochemical composition and evaluate the anti-inflammatory effect of essential oils (EO) obtained from four different Citrus species. Mice were treated with EO obtained from C. limon, C. latifolia, C. aurantifolia or C. limonia (10 to 100 mg/kg, p.o.) and their anti-inflammatory effects were evaluated in chemical induced inflammation (formalin-induced licking response) and carrageenan-induced inflammation in the subcutaneous air pouch model. A possible antinociceptive effect was evaluated in the hot plate model. Phytochemical analyses indicated the presence of geranial, limonene, γ-terpinene and others. EOs from C. limon, C. aurantifolia and C. limonia exhibited anti-inflammatory effects by reducing cell migration, cytokine production and protein extravasation induced by carrageenan. These effects were also obtained with similar amounts of pure limonene. It was also observed that C. aurantifolia induced myelotoxicity in mice. Anti-inflammatory effect of C. limon and C. limonia is probably due to their large quantities of limonene, while the myelotoxicity observed with C. aurantifolia is most likely due to the high concentration of citral. Our results indicate that these EOs from C. limon, C. aurantifolia and C. limonia have a significant anti-inflammatory effect; however, care should be taken with C. aurantifolia.

    Seeking for new medicinal compounds in plants used in traditional medicine, which grow in Venezuela, we investigated the anti-inflammatory activity of the leaf hexane extract (HE) and several fractions obtained from sp. Bursera simaruba (L.) Sarg. (Indio desnudo) using carrageenan-induced paw edema inflammation. Oral administration of leaf HE as well I (91-100) fraction, and compounds VIII 25-26 and VIII 29, inhibited the carrageenan-induced paw edema with different capacity and time course, over a period of 7h. The anti-inflammatory effect was comparable to that of the reference drug phenylbutazone (80 mg/kg, p.o.). Included in fraction I (91-100), Vitamin E was identified as one of its components and compound VIII 29 was identified as a methyl-beta-peltatin A. The comparison of the anti-inflammatory activity of VIII 29 fraction with the corresponding standard of methyl-beta-peltatin A, suggest that this compound could be one of the active principles involved in the anti-inflammatory activity of Bursera simaruba (L.) Sarg. leave. Our results contribute to the pharmacological support of the use of Bursera simaruba (L.) Sarg. as anti-inflammatory in the ethnomedicinal practice. Copyright 2004 Elsevier Ireland Ltd.

    Full Text Available Agrimony (Agrimonia eupatoria L. (Ae is used in traditional medicine to treat inflammatory and oxidative related diseases. Therefore, this study focuses on the anti-inflammatory and analgesic potential of Ae infusion (AeI. Phenolic compounds characterization was achieved by HPLC-PDA-ESI/MSn. To evaluate antioxidant potential, 2,2-diphenyl-1-picrylhydrazyl (DPPH, superoxide anion, hydroxyl radical, and SNAP assays were used. In vitro anti-inflammatory activity of AeI was investigated in LPS-stimulated macrophages by measuring the NO production. In vivo anti-inflammatory activity was validated using the mouse carrageenan-induced paw edema model. Peripheral and central analgesic potential was evaluated using the acetic acid-induced writhing and hot-plate tests, respectively, as well as the formalin assay to assess both activities. The safety profile was disclosed in vitro and in vivo, using MTT and hematoxylin assays, respectively. Vitexin, quercetin O-galloyl-hexoside, and kaempferol O-acetyl-hexosyl-rhamnoside were referred to in this species for the first time. AeI and mainly AePF (Ae polyphenolic fraction showed a significant antiradical activity against all tested radicals. Both AeI and AePF decreased NO levels in vitro, AePF being more active than AeI. In vivo anti-inflammatory and analgesic activities were verified for both samples at concentrations devoid of toxicity. Agrimony infusion and, mainly, AePF are potential sources of antiradical and anti-inflammatory polyphenols.

    Full Text Available The Unani eye drop is an ophthalmic formulation prepared for its beneficial effects in the inflammatory and allergic conditions of the eyes. In the present study, the Unani eye drop formulation was prepared and investigated for its anti-inflammatory and antihistaminic activity, using in vivo and in vitro experimental models respectively. The Unani eye drop formulation exhibited significant anti-inflammatory activity in turpentine liniment-induced ocular inflammation in rabbits. The preparation also showed antihistaminic activity in isolated guinea-pig ileum. The anti-inflammatory and antihistaminic activity of eye drop may be due to presence of active ingredients in the formulation. Although there are many drugs in Unani repository which are mentioned in classical books or used in Unani clinical practice effectively in treatment of eye diseases by various Unani physicians. Inspite of the availability of vast literature, there is a dearth of commercial Unani ocular preparations. So, keeping this in mind, the eye drop formulation was prepared and its anti-inflammatory and antihistaminic activity was carried out in animal models. Thus, in view of the importance of alternative anti-inflammatory and anti- allergic drugs, it becomes imperative to bring these indigenous drugs to the front foot and evaluate their activities.

    Several species of the family Bromeliaceae are characterized by the production of proteases in unusual amounts, especially in fruits. Bromelain, an extract rich in cysteine endopeptidases obtained from Ananas comosus L., and a few other proteases have been used as anti-inflammatory agents for some years, but bromelain is still mainly being used as alternative and/or complementary therapy to the treatment with glucocorticoids, nonsteroidal antirheumatics, and immunomodulators. In this study, the anti-inflammatory action of a partially purified extract from Pseudananas macrodontes (Morr.) Harms fruits (PPE(Pm)) is presented, whose main components are cysteine endopeptidases. The effect of PPE(Pm) was assessed in carrageenan-induced and serotonin-induced rat paw edema, as well as in the cotton pellet granuloma model. Doses with equal proteolytic activity of PPE(Pm) and bromelain produced significantly similar anti-inflammatory responses in the acute inflammatory models assayed, supporting the hypothesis that proteolytic activity could be responsible for the anti-inflammatory action. On the contrary, comparable anti-inflammatory effects of PPE(Pm) and bromelain in the chronic inflammatory assay required a much lower proteolytic activity content of PPE(Pm), which could be due to a differential affinity for the protein target involved in this process.

    Full Text Available Objective: To evaluation of analgesic and anti-inflammatory properties of the fruits of Vernonia anthelmintica (L Willd. (V. anthelmintica. Method: Hot plate method in mice, acetic acid induced writhing response in mice, tail immersion test and carrageenan-induced paw edema in rats and cotton pellet induced granuloma in rats method were used for screening analgesic and anti-inflammatory properties of the fruit of V. anthelmintica (family: Asteraceae. Results: The result of the study showed that the ethanolic extract of V. anthelmintica (100 and 200 mg/kg body weight, p.o. fruits possed peripheral and central analgesic activity in animal model. The V. anthelmintica fruits extract showed in vivo anti-inflammatory activity on acute and chronic anti-inflammatory activity models in rats. Conclusions: On the basis of result it can be concluded that saponins, steroids, tannins and flavonoids are the major constituents that are present in the fruits of V. anthelmintica which may be responsible for its analgesic and anti-inflammatory activity.

    Full Text Available The effects of Crotalus durissus terrificus venom (Cdt were analyzed with respect to the susceptibility and the inflammatory mediators in an experimental model of severe envenomation. BALB/c female mice injected intraperitoneally presented sensibility to Cdt, with changes in specific signs, blood biochemical and inflammatory mediators. The venom induced reduction of glucose and urea levels and an increment of creatinine levels in serum from mice. Significant differences were observed in the time-course of mediator levels in sera from mice injected with Cdt. The maximum levels of IL-6, NO, IL-5, TNF, IL-4 and IL-10 were observed 15 min, 30 min, 1, 2 and 4 hours post-injection, respectively. No difference was observed for levels of IFN-γ. Taken together, these data indicate that the envenomation by Cdt is regulated both pro- and anti-inflammatory cytokine responses at time-dependent manner. In serum from mice injected with Cdt at the two first hours revealed of pro-inflammatory dominance. However, with an increment of time an increase of anti-inflammatory cytokines was observed and the balance toward to anti-inflammatory dominance. In conclusion, the observation that Cdt affects the production of pro- and anti-inflammatory cytokines provides further evidence for the role played by Cdt in modulating pro/anti-inflammatory cytokine balance.

    Neuroinflammation is a complex pathological process usually results from abnormal microglial activation, thus, intervention in a microglial stimulation pathway could be a promising approach for the treatment of neurodegenerative diseases. Luteolin is an important bioflavonoid possesses anti-inflammatory properties, which is widely studied over these years. Light emitting diode (LED) therapy is reported to be a potential therapeutic strategy for many diseases including neurodegenerative diseases. However, little is known about the anti-inflammatory effect of LED therapy on activated microglial cells, even less is known whether there is a synergistic anti-inflammatory effect exist in LED and luteolin therapy. In this study, we aimed to confirm the anti-inflammatory effect of luteolin and LED combination therapy in lipopolysaccharide (LPS)-stimulated BV2 microglial cells. We showed that luteolin inhibited LPS-induced cytotoxicity, tumor necrosis factor alpha (TNFα) and interleukin-6 (IL-6) production through modulation of p38 and extracellular signal-regulated kinase (ERK) signaling in BV2 cells. In addition, LED therapy enhanced the anti-inflammatory effect of luteolin. These results suggest that a synergistic effect between luteolin and LED could be a new effective therapy in relieving neuroinflammation.

    Intake of long-chain omega-3 polyunsaturated fatty acids (LC-n3-PUFA) is commonly recognized to reduce cardiovascular disease (CVD). In previous studies, cold-pressed whale oil (CWO) and cod liver oil (CLO) were given as a dietary supplement to healthy volunteers. Even though CWO contains less than half the amount of LC-n3-PUFA of CLO, CWO supplement resulted in beneficial effects on anti-inflammatory and CVD risk markers compared to CLO. In the present study, we prepared virtually lipid-free extracts from CWO and CLO and evaluated the antioxidative capacity (AOC) and anti-inflammatory effects. Oxygen radical absorbance capacity (ORAC) and ferric reducing antioxidant power (FRAP) assays were used to test the AOC, and the results indicated high levels of antioxidants present in all extracts. The anti-inflammatory effects of the extracts were tested with lipopolysaccharide- (LPS-) treated THP-1 cells, measuring its ability to reduce cytokine and chemokine secretion. Several CWO extracts displayed anti-inflammatory activity, and a butyl alcohol extract of CWO most effectively reduced TNF- α (50%, p < 0.05) and MCP-1 (85%, p < 0.001) secretion. This extract maintained a stable effect of reducing MCP-1 secretion (60%, p < 0.05) even after long-term storage. In conclusion, CWO has antioxidant and anti-inflammatory activities that may act in addition to its well-known LC-n3-PUFA effects.

    Full Text Available Ballota pseudodictamnus (L. Benth. (Lamiaceae, Salvia fruticosa Mill. (Lamiaceae and Thapsia garganica L. (Apiaceae are three well-known medicinal plants from the Libyan flora, which have long been used for the treatment of inflammations. The aim of the present study was to investigate, for the first time, the anti-inflammatory property of the methanol (MeOH extracts of the aerial parts of these plants. Shade-dried and ground aerial parts of B. pseudodictamnus, S. fruticosa and T. garganica were Soxhlet-extracted with MeOH. The extracts were concentrated by evaporation under reduced pressure at 40°C. The anti-inflammatory activity of the extracts was evaluated using the carrageenan-induced mice paw edema model. The administration of the extracts at a dose of 500 mg/kg body weight produced statistically significant inhibition (p < 0.05 of edema within 3 h of carrageenan administration. The results demonstrated significant anti-inflammatory properties of the test extracts. Among the extracts, the S. fruticosa extract exhibited the most significant inhibition of inflammation after 3 h (62.1%. Thus, S. fruticosa could be a potential source for the discovery and development of newer anti-inflammatory ‘leads’ for drug development. The anti-inflammatory activity of B. pseudodictamnus and S. fruticosa could be assumed to be related to high levels of phenolic compounds, e.g., flavonoids, present in these plants.

    Olive [Olea europaea L. (Oleaceae)] is a long-lived evergreen tree that is widespread in different parts of the world. Olive oil has been reported to relieve pain; however, there is still insufficient data in the literature on the subject. Thus, it is considered worthwhile investigating the antinociceptive and anti-inflammatory effects of olive oil in adult male Balb/C mice. The antinociceptive effects were studied using formalin, hot plate and writhing tests. The acute anti-inflammatory effects of olive oil in mice were studied using xylene ear edema test. Olive oil (1, 5 and 10 ml/kg body wt.) was injected intraperitoneally. Intact animals served as controls. Our results showed that the olive oil only decreased the second phase of formalin-induced pain. In the hot plate test, olive oil did not raise the pain threshold over the 60 min duration of the test. Olive oil exhibited antinociceptive activity against writhing-induced pain by acetic acid. In the xylene ear edema test, olive oil showed significant anti-inflammatory activity in the mice. The present data indicated that olive oil has antinociceptive and anti-inflammatory effects in mice but further investigation of these effects is required to elucidate the mechanism(s) involved in analgesic and anti-inflammatory effects of Olea europaea oil.

    An ethnopharmacological survey indicates that the genus Byrsonima has some medicinal species that are commonly found in the Brazilian Cerrado and has been used as an anti-inflammatory and for gastroduodenal disorders. The aim of this study was to evaluate the anti-inflammatory and antioxidant activity along with qualitative chemical characterization of the methanolic extract of the leaves of Byrsonima verbascifolia (BvME) obtained by exhaustive percolation. The data from the chemical analyses by liquid chromatography-mass spectrometry led to tentative identification of 42 compounds belonging to proanthocyanidins, galloyl quinic acid derivatives, flavonoids, and triterpene glycoside derivatives. BvME contain flavonoids and show an antioxidative activity. The methanolic extract administered intraperitoneally at doses of 50, 100, or 300 mg/kg showed a significant reduction in paw edema and modulated the neutrophil influx in a mouse model. Furthermore, the anti-edematogenic activity of the extract provided in smaller doses (12.5 and 25 mg/kg) was also demonstrated in a mouse paw edema model. The extract inhibited NO production by macrophages induced by lipopolysaccharide. We presume that the anti-inflammatory effects of BvME are due to a combination of compounds present in B. verbascifolia, including catechins (procyanidins), flavonoids, and triterpene glycosides and that these anti-inflammatory actions should be mediated, at least partly, through the inhibition of NO production. This study supports and validates the ethnopharmacological uses of B. verbascifolia as an anti-inflammatory.

    Full Text Available Protective mechanisms against drug-induced liver injury are actively being searched to identify new therapeutic targets. Among them, the anti-inflammatory N-acyl ethanolamide (NAE-peroxisome proliferators activated receptor alpha (PPARα system has gained much interest after the identification of its protective role in steatohepatitis and liver fibrosis. An overdose of paracetamol (APAP, a commonly used analgesic/antipyretic drug, causes hepatotoxicity, and it is being used as a liver model. In the present study, we have analyzed the impact of APAP on the liver NAE-PPARα system. A dose-response (0.5–5–10–20 mM and time-course (2–6–24 h study in human HepG2 cells showed a biphasic response, with a decreased PPARα expression after 6-h APAP incubation followed by a generalized increase of NAE-PPARα system-related components (PPARα, NAPE-PLD, and FAAH, including the NAEs oleoyl ethanolamide (OEA and docosahexaenoyl ethanolamide, after a 24-h exposure to APAP. These results were partially confirmed in a time-course study of mice exposed to an acute dose of APAP (750 mg/kg. The gene expression levels of Pparα and Faah were decreased after 6 h of treatment and, after 24 h, the gene expression levels of Nape-pld and Faah, as well as the liver levels of OEA and palmitoyl ethanolamide, were increased. Repeated APAP administration (750 mg/kg/day up to 4 days also decreased the expression levels of PPARα and FAAH, and increased the liver levels of NAEs. A resting period of 15 days completely restored these impairments. Liver immunohistochemistry in a well-characterized human case of APAP hepatotoxicity confirmed PPARα and FAAH decrements. Histopathological and hepatic damage (Cyp2e1, Caspase3, αSma, Tnfα, and Mcp1-related alterations observed after repeated APAP administration were aggravated in the liver of Pparα-deficient mice. Our results demonstrate that the anti-inflammatory NAE-PPARα signaling system is implicated in liver

    Nonsteroidal anti-inflammatory drugs (NSAIDs) are one of the most frequently prescribed drugs for the treatment of sciatica. A previous Cochrane review on the efficacy of NSAIDs summarised findings for acute and chronic low back pain (LBP) and sciatica. This is an update of the original review (2008) focusing on people suffering from sciatica. To determine the efficacy of NSAIDs in pain reduction, overall improvement, and reported side effects in people with sciatica. We performed electronic searches up to 24 June 2015 in the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, PubMed, and two trials registers. We searched reference lists of included studies and relevant reviews on the topics for additional trials. We included randomised controlled trials (double-blind, single-blind, and open-label) that assessed the efficacy of NSAIDs in sciatica. We included all trials that compared NSAIDs to placebo, to other NSAIDs, or to other medication. Additional interventions were allowed if there was a clear contrast for the treatment with NSAIDs in the trial. Three review authors independently assessed the risk of bias and extracted the data. Where feasible we calculated pooled results using Review Manager 5.3. We reported pain relief outcomes using mean difference (MD) with 95% confidence intervals (95% CI). We used risk ratios (RR) with 95% CI to report global improvement of treatment, adverse effects, and additional medication. We performed a meta-analysis if possible. We assessed level of evidence using the GRADE approach. We used standard methodological procedures recommended by The Cochrane Collaboration. We included 10 trials reported in 9 publications (N = 1651). Only one trial out of 10 was assessed at low risk of bias. Five trials used the currently recommended daily dose for the drug, and two trials used lower daily doses available over the counter. Three trials investigated NSAIDs no longer approved for human use. The follow-up duration

The aim of the study was to investigate anti-inflammatory, gastroprotective and anti-ulcerogenic activities of a mass spectrometry standardized methanolic extract of Gracilaria changii. Methods Methanolic extract of Gracilaria changii (MeOHGCM6 extract) was prepared and standardized using mass spectrometry (MS). Anti-inflammatory activities of MeOHGCM6 extract were examined by treating U937 cells during its differentiation with 10 μg/ml MeOHGCM6 extract. Tumour necrosis factors-α (TNF-α) response level and TNF-α and interleukin-6 (IL-6) gene expression were monitored and compared to that treated by 10 nM betamethasone, an anti-inflammatory drug. Gastroprotective and anti-ulcerogenic activities of MeOHGCM6 extract were examined by feeding rats with MeOHGCM6 extract ranging from 2.5 to 500 mg/kg body weight (b.w.) following induction of gastric lesions. Production of mucus and gastric juice, pH of the gastric juice and non-protein sulfhydryls (NP-SH) levels were determined and compared to that fed by 20 mg/kg b.w. omeprazole (OMP), a known anti-ulcer drug. Results MS/MS analysis of the MeOHGCM6 extracts revealed the presence of methyl 10-hydroxyphaeophorbide a and 10-hydroxypheophytin a, known chlorophyll proteins and several unidentified molecules. Treatment with 10 μg/ml MeOHGCM6 extract during differentiation of U937 cells significantly inhibited TNF-α response level and TNF-α and IL-6 gene expression. The inhibitory effect was comparable to that of betamethasone. No cytotoxic effects were recorded for cells treated with the 10 μg/ml MeOHGCM6 extract. Rats fed with MeOHGCM6 extract at 500 mg/kg b.w. showed reduced absolute ethanol-induced gastric lesion sizes by > 99% (p < 0.05). This protective

    Full Text Available Simple synthesis of modafinil derivatives and their biological activity are described. The key synthetic strategies involve substitution and coupling reactions. We determined the anti-inflammatory effects of modafinil derivatives in cultured BV2 cells by measuring the inhibition of nitrite production and expression of iNOS and COX-2 after LPS stimulation. It was found that for sulfide analogues introduction of aliphatic groups on the amide part (compounds 11ad resulted in lower anti-inflammatory activity compared with cyclic or aromatic moieties (compounds 11ek. However, for the sulfoxide analogues, introduction of aliphatic moieties (compounds 12ad showed higher anti-inflammatory activity than cyclic or aromatic fragments (compounds 12ek in BV-2 microglia cells.

    Full Text Available The red seaweed Galaxaura marginata (Ellis & Solander Lamouroux, well known by the antibacterial activity of its polar extract and the cytotoxic activity of its oxygenated desmosterol, showed anti-inflammatory action in its apolar fraction. Topical anti-inflammatory activity was observed in samples collected at São Sebastião channel, northern littoral of São Paulo State, Brazil. The apolar extract and its fractions obtained through Thin-Layer Chromatography (TLC reduced the topical inflammation produced by croton oil in mouse ear. Such data indicated that the apolar extract from the marine red alga G. marginata displayed anti-inflammatory activity (since 1mg/ear extract reduced 95±0.5% inflammation, which could be the result of the synergic activity of the four fractions present in the apolar extract.

    Oral administration of nonsteroidal anti-inflammatory drugs (NSAIDs) was frequently associated with serious adverse effects. Inspired by curcumin-a naturally traditional Chinese medicine, a series of curcumin derivatives containing NSAIDs, used for transdermal application, were synthesized and screened for their anti-inflammatory activities in vitro and in vivo. Compared with curcumin and parent NSAID (salicylic acid and salsalate), topical application of A11 and B13 onto mouse ear edema, prior to TPA treatment markedly suppressed the expression of IL-1β, IL-6 and TNF-α, respectively. Mechanistically, A11 and B13 blocked the phosphorylation of IκBα and suppressed the activation of p65 and IκBα. It was found that A11 and B13 may be potent anti-inflammatory agents for the treatment of inflammatory diseases. Copyright © 2015 Elsevier Ltd. All rights reserved.

    2016-01-01

    Glucagon-like peptide-1 (GLP-1) is an incretin hormone mainly secreted from intestinal L cells in response to nutrient ingestion. GLP-1 has beneficial effects for glucose homeostasis by stimulating insulin secretion from pancreatic beta-cells, delaying gastric emptying, decreasing plasma glucagon, reducing food intake, and stimulating glucose disposal. Therefore, GLP-1-based therapies such as GLP-1 receptor agonists and inhibitors of dipeptidyl peptidase-4, which is a GLP-1 inactivating enzyme, have been developed for treatment of type 2 diabetes. In addition to glucose-lowering effects, emerging data suggests that GLP-1-based therapies also show anti-inflammatory effects in chronic inflammatory diseases including type 1 and 2 diabetes, atherosclerosis, neurodegenerative disorders, nonalcoholic steatohepatitis, diabetic nephropathy, asthma, and psoriasis. This review outlines the anti-inflammatory actions of GLP-1-based therapies on diseases associated with chronic inflammation in vivo and in vitro, and their molecular mechanisms of anti-inflammatory action.

    Cocos nucifera L. (family: arecaceae) is generally straight unbranched plant, traditionally cultivated for its fruit (coconut) in home gardens. In the present study, anti-inflammatory and antinociceptive (analgesic) activity of hydromethanol extract of Cocos nucifera L. (HECN) was evaluated in animal models. HECN showed significant (p < 0.05) and dosedependent anti-inflammatory activity in carrageenan induced paw oedema models of inflammation and the result was comparable with the standard drug diclofenac. In addition, the extract also showed highly significant (p < 0.01) antinociceptive activity. HECN treated group showed increase in the reaction time in hot plate method and decrease the writhing induced by acetic acid in mice when compared with control group animal. The anti-inflammatory and antinociceptive activity observed in the present study could be attributed largely to the presence of its antioxidant phytoconstituents such as flavonoid, saponin and polyphenols.

    Pomegranate (Punica granatum L.) has been used for centuries for the treatment of inflammatory diseases. However, there is a lack of comprehensive information focused on the properties of a certain pomegranate (poly)phenolic profile to cure pain and gastric injury induced by anti-inflammatory drugs. This study investigated the systemic effects of different doses of a HPLC-characterized pomegranate extract on the formalin-induced nociceptive behavior in mice. The effect of the extract against gastric injury caused by non-steroidal anti-inflammatory drugs and ethanol was also assessed. Pomegranate reduced nociception in both phases of the formalin test, suggesting central and peripheral activities to inhibit nociception. Indomethacin-induced gastric injury was not produced in the presence of pomegranate, which also protected against ethanol-induced gastric lesions. The present results reinforce the benefits of pomegranate (poly)phenolics in the treatment of pain as well as their anti-inflammatory properties.

    This study investigated some pharmacological properties of virgin coconut oil (VCO), the natural pure oil from coconut [Cocos nucifera Linn (Palmae)] milk, which was prepared without using chemical or high-heat treatment. The anti-inflammatory, analgesic, and antipyretic effects of VCO were assessed. In acute inflammatory models, VCO showed moderate anti-inflammatory effects on ethyl phenylpropiolate-induced ear edema in rats, and carrageenin- and arachidonic acid-induced paw edema. VCO exhibited an inhibitory effect on chronic inflammation by reducing the transudative weight, granuloma formation, and serum alkaline phosphatase activity. VCO also showed a moderate analgesic effect on the acetic acid-induced writhing response as well as an antipyretic effect in yeast-induced hyperthermia. The results obtained suggest anti-inflammatory, analgesic, and antipyretic properties of VCO.

  1. Neuro-immune interactions via the cholinergic anti-inflammatory pathway

    Gallowitsch-Puerta, Margot; Pavlov, Valentin A.

    2010-01-01

    The overproduction of TNF and other cytokines can cause the pathophysiology of numerous diseases. Controlling cytokine synthesis and release is critical for preventing unrestrained inflammation and maintaining health. Recent studies identified an efferent vagus nerve-based mechanism termed “the cholinergic anti-inflammatory pathway” that controls cytokine production and inflammation. Here we review current advances related to the role of this pathway in neuro-immune interactions that prevent excessive inflammation. Experimental evidence indicates that vagus nerve cholinergic anti-inflammatory signaling requires alpha7 nicotinic acetylcholine receptors expressed on non-neuronal cytokine producing cells. Alpha7 nicotinic acetylcholine receptor agonists inhibit cytokine release and protect animals in a variety of experimental lethal inflammatory models. Knowledge related to the cholinergic anti-inflammatory pathway can be exploited in therapeutic approaches directed towards counteracting abnormal chronic and hyper-activated inflammatory responses.

    Since the discovery of glucocorticoids in the 1940s and the recognition of their anti-inflammatory effects, they have been amongst the most widely used and effective treatments to control inflammatory and autoimmune diseases. However, their clinical efficacy is compromised by the metabolic effects of long-term treatment, which include osteoporosis, hypertension, dyslipidaemia and insulin resistance/type 2 diabetes mellitus. In recent years, a great deal of effort has been invested in identifying compounds that separate the beneficial anti-inflammatory effects from the adverse metabolic effects of glucocorticoids, with limited effect. It is clear that for these efforts to be effective, a greater understanding is required of the mechanisms by which glucocorticoids exert their anti-inflammatory and immunosuppressive actions. Recent research is shedding new light on some of these mechanisms and has produced some surprising new findings. Some of these recent developments are reviewed here. PMID:20398732

    The anti-nociceptive effect of ethanolic extract of 11 traditionally used Jordanian plants was studied by using the acetic acid-induced writhing and hot-plate test in mice. The anti-inflammatory effect of these plants was determined by xylene-induced ear oedema in mice and cotton pellet granuloma test in rats. Mentha piperita, Cinnamomum zeylanicum, Apium graveolens, Eucalyptus camaldulentis, and Ruta graveolens possess an anti-nociceptive effect against both acetic acid-induced writhing and hot plate-induced thermal stimulation. M. piperita, Jasminum officinale, Commiphora molmol, and Beta vulgaris possess an anti-inflammatory effect against acute (xylene-induced ear oedema) and chronic (cotton-pellet granuloma) inflammation. The anti-nociceptive and anti-inflammatory effects were dose dependent. These data affirm the traditional use of some of these plants for painful and inflammatory conditions.

    Full Text Available Laura J Hunter, David M Wood, Paul I DarganClinical Toxicology, Guy’s and St Thomas’ NHS Foundation Trust, London, UKAbstract: The nonsteroidal anti-inflammatory drugs (NSAIDs are widely used for their analgesic, anti-inflammatory and antipyretic actions. They are commonly taken in overdose in many areas of the world. The majority of patients with acute NSAID overdose will remain asymptomatic or develop minor self-limiting gastrointestinal symptoms. However, serious clinical sequelae have been reported in patients with acute NSAID overdose and these include convulsions, metabolic acidosis, coma and acute renal failure. There appear to be some differences between the NSAIDs in terms of the relative risk of these complications; in particular mefenamic acid is most commonly associated with convulsions. The management of these serious clinical features is largely supportive and there are no specific antidotes for acute NSAID toxicity.Keywords: nonsteroidal anti-inflammatory drugs (NSAID, ibuprofen, toxicity, poisoning, overdose, management

    Accumulating evidence supports an association between depression and inflammatory processes, a connection that seems to be bidirectional. Clinical trials have indicated antidepressant treatment effects for anti-inflammatory agents, both as add-on treatment and as monotherapy. In particular......, nonsteroidal anti-inflammatory drugs (NSAIDs) and cytokine-inhibitors have shown antidepressant treatment effects compared to placebo, but also statins, poly-unsaturated fatty acids, pioglitazone, minocycline, modafinil, and corticosteroids may yield antidepressant treatment effects. However, the complexity...... of the inflammatory cascade, limited clinical evidence, and the risk for side effects stress cautiousness before clinical application. Thus, despite proof-of-concept studies of anti-inflammatory treatment effects in depression, important challenges remain to be investigated. Within this paper, we review...

    In recent years, the fruits of native Brazilian plant species with anti-inflammatory property have gained prominence due to their properties comparable to traditional medicines. This study aimed to chemically characterize and evaluate the anti-inflammatory and antihyperalgesic activity of Byrsonima cydoniifolia fruit, which is widely used to manufacture ice cream and jellies. Our results revealed that the fruit exhibits flavonoid derivatives and stilbenes, as trans-piceatannol and resveratrol, as main secondary metabolites. In mice, the hydroethanolic extract of fruit reduced the edema, migration of polymorphonuclear leukocytes into the peritoneal cavity, as well as abdominal writhings. The results demonstrated, for the first time, the presence of stilbenoids in the Byrsonima genus and the anti-inflammatory and antihyperalgesic effect of Byrsonima cydoniifolia fruits, supporting its potential as a nutraceutical food.

    Full Text Available The purpose of this research is to evaluate the anti-inflammatory and analgesic activities of infusion and methanolic extract from avocado seeds. The anti-inflammatory activity was determined using carrageenan-induced paw edema in mice. The analgesic activity was assessed using acetic acid stimuli to induce peripheral pain in mice. Results of this research showed that both all level doses of infusion and methanolic extract of avocado seeds have a significant reduction on the mice paw edema. All level doses of methanolic extract of avocado seeds have a significant reduction on the number of abdominal writhes induced by acetic acid, but only the lowest dose of infusion showed a significant reduction. Our findings suggest that avocado seeds contains potential anti-inflammatory and analgesic compounds which support its traditional use. Further phytochemical studies are required to determine the active compounds are actually responsible for such properties.

    Rosa canina L. is a medicinal plant largely used in traditional folk medicine. Several compounds from rose hip extracts were reported to display in vitro anti-inflammatory activities. The in vivo effects of Rosa canina extracts are still poorly investigated. In the present study the anti-inflammatory and the gastroprotective effects of a hydroalcoholic crude extract of Rosa canina fruits were tested in rat. The anti-inflammatory activity of the extract was tested on the carrageenin-induced rat paw edema assay. The gastroprotective effect was investigated on the ethanol-induced gastric damage model. The in vitro antioxidant activity of this extract was also quantified using the Briggs-Rauscher oscillating reaction, the Trolox Equivalent Antioxidant Capacity method, and the Total Phenolic Content. Data show that the Rosa canina extract inhibits the development of carrageenin-induced edema; the anti-inflammatory power is similar to that of indomethacin. The antiedema effect was more significant using a higher dose of the extract. The total score expressing gastric damage was lower in Rosa canina pre-treated stomachs with respect to unpre-treated ones, although the antiulcerogenic effectiveness was not statistically significant. The antiulcerogenic effectiveness was not statistically detectable, even if the total score expressing gastric damage was lower in Rosa canina stomachs from pre-treated rats with respect to unpre-treated ones. Chemical analysis revealed that the extract owns a good antioxidant activity that may also contribute to the anti-inflammatory effects observed in vivo. Altogether, the present data demonstrate the anti-inflammatory property of Rosa canina suggesting its potential role as adjuvant therapeutic tool for the management of inflammatory-related diseases.

    Objective Osteoarthritis (OA) is one of the leading causes of disability in the adult population. Common nonoperative treatment options include nonsteroidal anti-inflammatory drugs (NSAIDs), intra-articular corticosteroids, and intra-articular injections of hyaluronic acid (HA). HA is found intrinsically within the knee joint providing viscoelastic properties to the synovial fluid. HA therapy provides anti-inflammatory relief through a number of different pathways, including the suppression of pro-inflammatory cytokines and chemokines. Methods We conducted a systematic review to summarize the published literature on the anti-inflammatory properties of hyaluronic acid in osteoarthritis. Included articles were categorized based on the primary anti-inflammatory responses described within them, by the immediate cell surface receptor protein assessed within the article, or based on the primary theme of the article. Key findings aimed to describe the macromolecules and inflammatory-mediated responses associated with the cell transmembrane receptors. Results Forty-eight articles were included in this systematic review that focused on the general anti-inflammatory effects of HA in knee OA, mediated through receptor-binding relationships with cluster determinant 44 (CD44), toll-like receptor 2 (TLR-2) and 4 (TLR-4), intercellular adhesion molecule-1 (ICAM-1), and layilin (LAYN) cell surface receptors. Higher molecular weight HA (HMWHA) promotes anti-inflammatory responses, whereas short HA oligosaccharides produce inflammatory reactions. Conclusions Intra-articular HA is a viable therapeutic option in treating knee OA and suppressing inflammatory responses. HMWHA is effective in suppressing the key macromolecules that elicit the inflammatory response by short HA oligosaccharides.

  13. Differential ability of proinflammatory and anti-inflammatory macrophages to perform macropinocytosis.

    Macropinocytosis mediates the uptake of antigens and of nutrients that dictate the regulation of cell growth by mechanistic target of rapamycin complex 1 (mTORC1). Because these functions differ in proinflammatory and anti-inflammatory macrophages, we compared the macropinocytic ability of two extreme polarization states. We found that anti-inflammatory macrophages perform vigorous macropinocytosis constitutively, while proinflammatory cells are virtually inactive. The total cellular content of Rho-family GTPases was higher in anti-inflammatory cells, but this disparity failed to account for the differential macropinocytic activity. Instead, reduced activity of Rac/RhoG was responsible for the deficient macropinocytosis of proinflammatory macrophages, as suggested by the stimulatory effects of heterologously expressed guanine nucleotide-exchange factors or of constitutively active (but not wild-type) forms of these GTPases. Similarly, differences in the activation state of phosphatidylinositol 3-kinase (PtdIns3K) correlated with the macropinocytic activity of pro- and anti-inflammatory macrophages. Differences in PtdIns3K and Rho-GTPase activity were attributable to the activity of calcium-sensing receptors (CaSRs), which appear to be functional only in anti-inflammatory cells. However, agonists of PtdIns3K, including cytokines, chemokines, and LPS, induced macropinocytosis in proinflammatory cells. Our findings revealed a striking difference in the macropinocytic ability of pro- and anti-inflammatory macrophages that correlates with their antigen-presenting and metabolic activity. © 2018 Redka et al.

    This study investigated the analgesic and anti-inflammatory effects of a water extract of Trachelospermum jasminoides (WET) in ICR mice. In HPLC analysis, the fingerprint chromatogram of WET was established. Acetic acid-induced writhing response and formalin-induced pain were examined the analgesics effects of WET. WET on lambda-Carrageenan(carr)-induced paw edema was performed. We investigate the anti-inflammatory mechanism of WET via studies of the activities of glutathione peroxidase (GPx), glutathione reductase (GRx) in the liver and the levels of malondialdehyde (MDA) and nitrite oxide (NO) in the edema paw. Serum NO and TNF-alpha were also measured. The fingerprint chromatogram of WET was established through HPLC analysis, and implies that WET contains the active ingredient gallic acid, chlorgenic acid, caffeic acid, taxifolin, isoquercitrin and quercetin. WET significantly inhibited the numbers of acetic acid-induced writhing responses and the formalin-induced pain in the late phase. In the anti-inflammatory test, WET inhibited the development of paw edema induced by carr. WET decreased the paw edema at the third, fourth and fifth hour after carr administration, and increased the activities of SOD, GPx and GRx in the liver tissue and decreased the MDA level in the edema paw at the third hour after carr injection. WET decreased the level of NO in edematous paw tissue and in serum level, and diminished the level of serum TNF-alpha at the fifth hour after carr injection. These results demonstrated that WET is an effective anti-inflammatory agent in carr-induced inflammation. WET probably exerts anti-inflammatory effects by suppressing TNF-alpha and NO. The anti-inflammatory mechanism of WET might be related to the decrease in the level of MDA in the edema paw via increasing the activities of SOD, GPx and GRx in the liver.

    The benefits of garlic to health have been proclaimed for centuries; however, only recently have Allium sativum and its derivatives been proposed as promising candidates for maintaining the homeostasis of the immune system. The complex biochemistry of garlic makes it possible for variations in processing to yield different preparations with differences in final composition and compound proportion. In this review, we assess the most recent experimental results, which indicate that garlic appears to enhance the functioning of the immune system by stimulating certain cell types, such as macrophages, lymphocytes, natural killer (NK) cells, dendritic cells, and eosinophils, by mechanisms including modulation of cytokine secretion, immunoglobulin production, phagocytosis, and macrophage activation. Finally, because immune dysfunction plays an important role in the development and progress of several diseases, we critically examined immunoregulation by garlic extracts and compounds isolated, which can contribute to the treatment and prevention of pathologies such as obesity, metabolic syndrome, cardiovascular disorders, gastric ulcer, and even cancer. We concluded that A. sativum modulates cytokine secretion and that such modulation may provide a mechanism of action for many of their therapeutic effects. PMID:25961060

    Full Text Available BACKGROUND Statins are HMG-CoA (3-hydroxy-3-methylglutaryl-coenzyme A reductase inhibitors well known for their hypolipidemic action. More recently, there has been an increased interest in pleiotropic effects of statins like anti-inflammatory action that occurs independent of their lipid lowering effect. Statins exert anti-inflammatory action by preventing the isoprenylation of Rho proteins, a family of small G proteins and subsequent disruption of their functions. Hence, the present study was planned to compare the anti-inflammatory effect of rosuvastatin with that of aspirin on acute inflammation, so that it could be utilised in acute inflammatory conditions as an adjuvant or as a monotherapy avoiding adverse effects of commonly used antiinflammatory agents like NSAIDS (nonsteroidal anti-inflammatory drugs. The aim of the study is to compare anti-inflammatory effect of rosuvastatin with that of aspirin on carrageenan-induced inflammation in albino rats. MATERIALS AND METHODS 18 adult albino rats weighing between 100-150 g of either sex were divided into 3 groups. Control, Standard and test receiving oral normal saline (2 mL/kg, aspirin (100 mg/kg and rosuvastatin (5 mg/kg drug solutions, respectively. Acute inflammation model of carrageenan-induced paw oedema was used as tool. An hour after the administration of the drugs to each group, paw oedema was induced with intradermal injection of 0.1 mL of carrageenan (1% into the plantar surface of the right hind paw of each rat. Volume of inflamed paw was determined using a plethysmometer immediately and also at 30, 60, 120 and 180 minutes after injection. Finally, mean paw volumes at different time intervals were calculated and percentage inhibition of paw oedema with standard and test drugs were determined. RESULTS Data was analysed using by Analysis of Variance (ANOVA. Results showed that rosuvastatin has statistically significant (P<0.05 anti-inflammatory action reflected by percentage

    The quintessential biological response to disease is inflammation. It is a driver and an important element in a wide range of pathological states. Pharmacological management of inflammation is therefore central in the clinical setting. Anti-inflammatory drugs modulate specific molecules involved in the inflammatory response; these drugs are traditionally classified as steroidal and non-steroidal drugs. However, the effects of these drugs are rarely limited to their canonical targets, affecting other molecules and altering biological functions with system-wide effects that can lead to the emergence of secondary therapeutic applications or adverse drug reactions (ADRs). In this study, relationships among anti-inflammatory drugs, functional pathways, and ADRs were explored through network models. We integrated structural drug information, experimental anti-inflammatory drug perturbation gene expression profiles obtained from the Connectivity Map and Library of Integrated Network-Based Cellular Signatures, functional pathways in the Kyoto Encyclopedia of Genes and Genomes (KEGG) and Reactome databases, as well as adverse reaction information from the U.S. Food and Drug Administration (FDA) Adverse Event Reporting System (FAERS). The network models comprise nodes representing anti-inflammatory drugs, functional pathways, and adverse effects. We identified structural and gene perturbation similarities linking anti-inflammatory drugs. Functional pathways were connected to drugs by implementing Gene Set Enrichment Analysis (GSEA). Drugs and adverse effects were connected based on the proportional reporting ratio (PRR) of an adverse effect in response to a given drug. Through these network models, relationships among anti-inflammatory drugs, their functional effects at the pathway level, and their adverse effects were explored. These networks comprise 70 different anti-inflammatory drugs, 462 functional pathways, and 1,175 ADRs. Network-based properties, such as degree

    The research and development process for novel drugs to treat inflammatory diseases is described, and several current issues and debates relevant to this are raised: the decline in productivity, attrition, challenges and trends in developing anti-inflammatory drugs, the poor clinical predictivity of experimental models of inflammatory diseases, heterogeneity within inflammatory diseases, 'improving on the Beatles' in treating inflammation, and the relationships between big pharma and biotechs. The pharmaceutical research and development community is responding to these challenges in multiple ways which it is hoped will lead to the discovery and development of a new generation of anti-inflammatory medicines. © 2013 Nordic Pharmacological Society.

    Full Text Available Symptoms of inflammation accompany a number of diseases. In order to mitigate them, folk medicine has used a variety of medicinal substances, including herbs and mushrooms. Lichens are less known organisms, containing specific secondary metabolites with interesting biological properties. One of their biological actions is the anti-inflammatory activity that has been confirmed by in vitro and animal studies. It has been proven that compounds and extracts from lichens inhibit the enzymes involved in the inflammatory process. The following paper is a review of research on the little-known anti-inflammatory properties of lichens.

    The synthesis and evaluation of the anti-inflammatory activity of some structure hybrids comprising basically the 5-hydroxy-3-methyl-1-phenyl-4-substituted-1H-pyrazole scaffold directly linked to a variety of heterocycles and functionalities, or annulated as pyrano[2,3-c]pyrazoles, is described. According to the in vivo results and a comprehensive structure-activity relationship study, five analogs (5, 10, 17, 19, and 27) displayed remarkable anti-inflammatory profiles showing distinctive % protection and ED 50 values, especially 10 and 27 (ED 50 35.7 and 38.7 μmol/kg, respectively) which were nearly equiactive to celecoxib (ED 50 32.1 μmol/kg). Compounds 10, 17, and 27 exhibited distinctive COX-2 inhibition with a noticeable COX-2 selectivity (SI values 7.83, 6.87, and 7.16, respectively), close to that of celecoxib (SI 8.68). Additionally, 5, 10, 17, 19, and 27 proved to be gastrointestinal tract safe (0-20% ulceration) and non-toxic, being well tolerated by the experimental animals up to 250 mg/kg orally and 80 mg/kg parenterally. Collectively, the in vivo ED 50 values for the most potent five derivatives agree with their in vitro COX-2 selectivity indices, suggesting their usefulness as selective anti-inflammatory COX-2 inhibitors. The bipyrazole 10 and the pyranopyrazole 27 could be considered as the most active members in this study, being nearly equiactive to celecoxib, besides their obvious selective COX-2 inhibition, high safety margin, and predicted pharmacokinetic (ADME-T) suitability for oral use. © 2017 WILEY-VCH Verlag GmbH & Co.

    KYKZL-1, a newly synthesized compound with COX/5-LOX dual inhibition, was subjected to the anti-inflammatory activity test focusing on its modulation of inflammatory mediators as well as intracellular MAPK and NF-κB signaling pathways. In acute ear edema model, pretreatment with KYKZL-1 (p.o.) dose-dependently inhibited the xylene-induced ear edema in mice with a higher inhibition than diclofenac. In a three-day TPA-induced inflammation, KYKZL-1 also showed significant anti-inflammatory activity with inhibition ranging between 20% and 64%. In gastric lesion test, KYKZL-1 elicited markedly fewer stomach lesions with a low index of ulcer as compared to diclofenac in rats. In further studies, KYKZL-1 was found to significantly inhibit the production of NO, PGE 2 , LTB 4 in LPS challenged RAW264.7, which is parallel to its attenuation of the expression of iNOS, COX-2, 5-LOX mRNAs or proteins and inhibition of phosphorylation of p38 and ERK MAPKs and activation of NF-κB. Taken together, our data indicate that KYKZL-1 comprises dual inhibition of COX and 5-LOX and exerts an obvious anti-inflammatory activity with an enhanced gastric safety profile via simultaneous inhibition of phosphorylation of p38 and ERK MAPKs and activation of NF-κB. - Highlights: • KYKZL-1 is designed to exhibit COX/5-LOX dual inhibition. • KYKZL-1 inhibits NO, PGE 2 and LTB 4 and iNOS, COX-2 and 5-LOX mRNAs and MAPKs. • KYKZL-1 inhibits phosphorylation of MAPKs. • KYKZL-1 inactivates NF-κB pathway

    During recent years, there has been growing interest in use of topical vehicle systems to assist in drug permeation through the skin. Drugs of interest are usually those that are problematic when given orally, such as piroxicam, a highly effective anti-inflammatory, anti-pyretic, and analgesic, but with the adverse effect of causing gastrointestinal ulcers. The present study investigated the in vitro and in vivo pharmacodynamic activity of a newly synthesized palm oil esters (POEs)-based nanocream containing piroxicam for topical delivery. A ratio of 25:37:38 of POEs: external phase: surfactants (Tween 80:Span 20, in a ratio 80:20), respectively was selected as the basic composition for the production of a nanocream with ideal properties. Various nanocreams were prepared using phosphate-buffered saline as the external phase at three different pH values. The abilities of these formulae to deliver piroxicam were assessed in vitro using a Franz diffusion cell fitted with a cellulose acetate membrane and full thickness rat skin. These formulae were also evaluated in vivo by comparing their anti-inflammatory and analgesic activities with those of the currently marketed gel. After eight hours, nearly 100% of drug was transferred through the artificial membrane from the prepared formula F3 (phosphate-buffered saline at pH 7.4 as the external phase) and the marketed gel. The steady-state flux through rat skin of all formulae tested was higher than that of the marketed gel. Pharmacodynamically, nanocream formula F3 exhibited the highest anti- inflammatory and analgesic effects as compared with the other formulae. The nanocream containing the newly synthesized POEs was successful for trans-dermal delivery of piroxicam.

    Full Text Available Nonsteroidal anti-inflammatory drugs (NSAIDs are able to effectively control the major symptoms of rheumatic diseases and widely used in real clinical practice. However, they may cause serious gastrointestinal (GI and cardiovascular (CV events. The prevention of these events is based on the estimation of whether risk factors (RFs are present.Objective: to estimate the presence of RFs in patients needing NSAIDs.Subjects and methods. A cross-sectional epidemiological survey was performed, during which 2021 physicians from 9 CIS countries questioned for 2 weeks at least 10 patients needing NSAIDs. The inclusion criterion was severe musculoskeletal pain (>40 mm on a 100-mm visual analogue scale (VAS or use of NSAIDs at the examination. Data were obtained on 21,185 patients (57.5% women and 42.5% men (mean age 50.5±14.1 years who had predominantly dorsalgia (56.6% and osteoarthritis (23.5%. The mean pain value was 62.2±25.2 mm.Results. 1.7, 11.3, and 25.3% of patients had history of gastrointestinal bleeding, ulcer, or dyspepsia, respectively; people over 65 years of age constituted 16.8%; those who took low-dose aspirin (LDA – 20.0%. The total number of patients at high risk for GI events was 29.0%. There were also common CV RFs: myocardial infarction or stroke (7.8%, coronary heart disease (17.8%, hypertension (37.7%, and diabetes mellitus (8.1%. The total number of patients at high risk for CV events (without SCOR assessment was 23.0%. Many high-risk patients who has already used NSAIDs received no effective prevention. Thus, 62.2% of the patients at high GI risk took gastroprotective drugs; 53.2% of those at high CV risk used LDA.Conclusion. A large number of patients needing active analgesic therapy have a serious risk for drug-induced complications. This limits the possibility of using NSAIDs and determines the need for effective prevention or use of alternative methods for analgesia.

    Aloe has been a very popular folk remedy for inflammation-related pathological conditions despite the lack of studies reporting its efficacy in vivo. The present study evaluated the anti-inflammatory effects of aloe components (aloin, aloesin and aloe-gel) known to be biologically active in the rat model of colitis. Male Sprague Dawley rats were fed experimental diets for 2 weeks before and during the induction of colitis. Drinking water containing 3% dextran sulfate sodium (DSS) was provided for 1 week to induce colitis. At the end of the experimental period, clinical and biochemical markers were compared. Plasma leukotriene B(4) (LTB(4)) and tumor necrosis factor-α (TNF-α) concentrations were significantly decreased in all groups supplemented with aloe components compared to the colitis control group (paloin, aloesin, or aloe-gel (p<0.05). Dietary supplementation of aloe components ameliorates intestinal inflammatory responses in a DSS-induced ulcerative colitis rat model. In particular, aloesin was the most potent inhibitor. Further studies are required for a more complete understanding of the specific mechanism of the action of these supplements. Copyright © 2011 Elsevier Inc. All rights reserved.

  12. Bacterial microbiota profiling in gastritis without Helicobacter pylori infection or non-steroidal anti-inflammatory drug use.

    Directory of Open Access Journals (Sweden)

    Xiao-Xing Li

    Full Text Available Recent 16S ribosomal RNA gene (rRNA molecular profiling of the stomach mucosa revealed a surprising complexity of microbiota. Helicobacter pylori infection and non-steroidal anti-inflammatory drug (NSAID use are two main contributors to gastritis and peptic ulcer. However, little is known about the association between other members of the stomach microbiota and gastric diseases. In this study, cloning and sequencing of the 16S rRNA was used to profile the stomach microbiota from normal and gastritis patients. One hundred and thirty three phylotypes from eight bacterial phyla were identified. The stomach microbiota was found to be closely adhered to the mucosa. Eleven Streptococcus phylotypes were successfully cultivated from the biopsies. One to two genera represented a majority of clones within any of the identified phyla. We further developed two real-time quantitative PCR assays to quantify the relative abundance of the Firmicutes phylum and the Streptococcus genus. Significantly higher abundance of the Firmicutes phylum and the Streptococcus genus within the Firmicutes phylum was observed in patients with antral gastritis, compared with normal controls. This study suggests that the genus taxon level can largely represent much higher taxa such as the phylum. The clinical relevance and the mechanism underlying the altered microbiota composition in gastritis require further functional studies.

    Full Text Available Brugada syndrome (BrS is an inherited cardiac disorder that is associated with an electrocardiogram pattern of ST segment elevation on right precordial leads and a high incidence of sudden death. Diagnosis requires documentation of a coved-type ST segment that occurs spontaneously or in the presence of a class IA or IC antiarrhythmic agent. A wide variety of other drugs, including antianginals, antidepressants, antipsychotics, and antihistamines, have been reported to unmask or induce the electrocardiographic and arrhythmic manifestations of BrS. This review focuses on drug-induced BrS phenotypes, prevalence, and underlying mechanisms.

    Directory of Open Access Journals (Sweden)

    Sajad Shahbazi

    Full Text Available Cyclooxygenase-2 (COX-2 plays an important role in memory consolidation and synaptic activity, the most fundamental functions of the brain. It converts arachidonic acid to prostaglandin endoperoxide H2. In contrast, if over-expressed, it causes inflammation in response to cytokine, pro-inflammatory molecule, and growth factor. Anti-inflammatory agents, by allosteric or competitive inhibition of COX-2, alleviate the symptoms of inflammation. Coxib family drugs, particularly celecoxib, are the most famous anti-inflammatory agents available in the market showing significant inhibitory effect on COX-2 activity. Due to high cardiovascular risk of this drug group, recent researches are focused on the investigation of new safer drugs for anti-inflammatory diseases. Natural compounds, particularly, phytochemicals are found to be good candidates for drug designing and discovery. In the present study, we performed in silico studies to quantitatively scrutinize the molecular interaction of curcumin and its structural analogs with COX-2, COX-1, FXa and integrin αIIbβIII to investigate their therapeutic potential as a cardiovascular-safe anti-inflammatory medicine (CVSAIM. The results of both ADMET and docking study indicated that out of all the 39 compounds studied, caffeic acid had remarkable interaction with proteins involved in inflammatory response. It was also found to inhibit the proteins that are involved in thrombosis, thereby, having the potential to be developed as therapeutic agent.

    Full Text Available Babassu oil extraction is the main income source in nut breakers communities in northeast of Brazil. Among these communities, babassu oil is used for cooking but also medically to treat skin wounds and inflammation, and vulvovaginitis. This study aimed to evaluate the anti-inflammatory activity of babassu oil and develop a microemulsion system with babassu oil for topical delivery. Topical anti-inflammatory activity was evaluated in mice ear edema using PMA, arachidonic acid, ethyl phenylpropiolate, phenol, and capsaicin as phlogistic agents. A microemulsion system was successfully developed using a Span® 80/Kolliphor® EL ratio of 6 : 4 as the surfactant system (S, propylene glycol and water (3 : 1 as the aqueous phase (A, and babassu oil as the oil phase (O, and analyzed through conductivity, SAXS, DSC, TEM, and rheological assays. Babassu oil and lauric acid showed anti-inflammatory activity in mice ear edema, through inhibition of eicosanoid pathway and bioactive amines. The developed formulation (39% A, 12.2% O, and 48.8% S was classified as a bicontinuous to o/w transition microemulsion that showed a Newtonian profile. The topical anti-inflammatory activity of microemulsified babassu oil was markedly increased. A new delivery system of babassu microemulsion droplet clusters was designed to enhance the therapeutic efficacy of vegetable oil.

    The anti-inflammatory effect of the leaves of Bryonia laciniosa was evaluated using carrageenan, dextran, histamine, serotonin induced rat paw oedema and cotton pellet induced granuloma (chronic) models in rats. In mice, carrageenan peritonitis test was performed for the extract by oral administration. The chloroform extract of Bryonia laciniosa (CEBL) exhibited significant anti-inflammatory effect at the dose 50, 100 and 200 mg/kg. Maximum inhibition (52.4%) was noted at the dose of 200 mg/kg after 3 h of drug treatment in carrageenan induced paw oedema, whereas the indomethacin (standard drug) produced 62.1% of inhibition. The extract exhibited significant anti-inflammatory activity in dextran induced paw oedema in a dose dependent manner. The extract also exhibited significant inhibition on the hind paw oedema in rats caused by histamine and serotonin respectively. In the chronic model (cotton pellet induced granuloma) the CEBL (200 mg/kg) and standard drug showed decreased formation of granuloma tissue by 50.1 and 57.3% (p<0.001) respectively. The extract also inhibited peritoneal leukocyte migration in mice. Thus, the present study revealed that the chloroform extract of Bryonia laciniosa exhibited significant anti-inflammatory activity in the tested models.

    Full Text Available In the present work, Caesalpinia bonduc seed coat extract (CBSCE has been evaluated for anti-inflammatory and analgesic activity C. bonduc seeds have been attributed with anti-inflammatory and analgesic properties in the folklore medicine. Here in our study, we have tried to carry out the systematic evaluation of the seed coat extract of C. bonduc to substantiate these claims. C. bonduc seed coat was extracted with 95% ethanol and concentrated; further, the extract was screened for anti-inflammatory and analgesic activity. The studies were carried using Carrageenan-induced Paw Edema, Egg albumin-induced paw edema, Eddy′s Hot Plate Test, Tail Immersion Method so as to prove acclaimed properties. The data was analyzed statistically by Students′ ′t′ test. The results indicate that seed coat extract has the ability to decrease the induced inflammation at varied doses in Carrageenan model as well as in the Egg albumin model in rats. The antinociceptive results indicate that the extract has the ability to increase the pain threshold of the animals and reduce the pain factor, thereby inducing analgesia. Thus, it can be concluded that CBSCE posses analgesic and anti-inflammatory activity.

    Four commercial gel preparations of topical anti-inflammatory agents have been assessed in six animal models commonly used to determine the biological activity of non-steroidal anti-inflammatory agents for systemic administration. Only UV-induced erythema of the skin, adjuvant induced arthritis and the measurement of vascular permeability proved suitable for differentiation of the potency of the four topical agents. Carrageenin-induced paw oedema, the cotton pellet test and the assessment of the pain threshold according to Randall and Selitto were of little value. The effects of the gel preparation of diclofenac (CAS 15307-86-5) diethylammonium (Voltaren Emulgel) were comparable to two preparations containing 1% and 5% active ingredient, respectively. Gel 4 showed low overall activity. The experiments demonstrated that some of the models used for the assessment of anti-inflammatory agent for systemic administration proved suitable for the testing of topical preparations and that percutaneous absorption was insufficient to elicit anti-inflammatory effect in the animals at sites remote from the site of application.

    Full Text Available Tabernaemontana catharinensis (Apocynaceae has been popularly used by folk medicine because of its anti-inflammatory, analgesic, and antiophidic properties. This study aims to analyze the flavonoids composition of the hydroethanolic extract and of the ethyl acetate (EtOAc and butanol (BuOH fractions of T. catharinensis leaves, as well as to evaluate their anti-inflammatory activity using in vivo models. The phytochemical profile, determined by High-Performance Liquid Chromatography–High-Resolution Electrospray Ionization-Mass Spectrometry (HPLC–HRESI-MS, showed the presence of flavonoids mainly having an isorhamnetin nucleus. The anti-inflammatory activity was evaluated in carrageenan-induced paw edema (pre- and post-treatment with oral administration of a T. catharinensis hydroethanolic extract (50, 100, and 150 mg/kg and of organic fractions (50 mg/kg. The extract and fractions showed antiedematogenic activity by decreasing myeloperoxidase (MPO production. In the zymosan-air-pouch model, the extract and fractions inhibited leukocyte migration and significantly decreased the levels of various proteins, such as MPO, interleukin (IL-1β, and tumor necrosis factor (TNF-α. The cytotoxicity was evaluated by the 3-(4,5-dimethylthiazol-2-yl-2,5-diphenyltetrazolium bromide (MTT assay, which revealed no cytotoxicity of the extract and the fractions. These results suggest that the hydroethanolic extract and organic fractions of T. catharinensis leaves have sufficient anti-inflammatory activity to support the popular use of this plant in the treatment of inflammatory disorders.

    Nigella sativa or "Kalonji" is a naturally occurring plant in Pakistan and other countries which possesses a wide range of medicinal properties, the anti-inflammatory property being one of these. Diclofenac sodium is a commonly used anti-inflammatory drug. The purpose of this study was to compare the anti-inflammatory effect of ethanolic extract of Nigella sativa seeds with that of diclofenac sodium in albino rats. This laboratory randomized controlled trial (RCT) was conducted in the Physiology Department, Services Institute of Medical Sciences (SIMS), Lahore. The study was carried out on 90 male albino rats. Five percent formalin in a dose of 50 µl was injected into sub-plantar surface of right hind paw of each rat to produce inflammation. The rats were randomly divided into three groups of thirty each. Group A was given normal saline (control); group B was given Nigella sativa seed extract; and group C received diclofenac sodium, as a reference drug. Increase in paw diameter, and total and differential leukocyte counts were measured as markers of inflammation. Nigella sativa seeds extract caused significant (pdiclofenac sodium; however, the extract was comparatively less potent than diclofenac sodium. The extract had no significant effect (p>0.05) on the total or differential leukocyte counts. Our results suggest that ethanolic extract of Nigella sativa seeds possesses potent anti-inflammatory effect, in albino rats however, this effect is comparatively less but prolonged than that produced by diclofenac sodium.

    Full Text Available Aloe emodin is isolated compound of aloe vera which is used traditionally as an anti-inflammatory agent. In vitro pharmacokinetic data suggest that glucuronosyl or sulfated forms of aloe emodin may provide some limitations in its absorption capacity. Aloe emodin was reported to have in vitro anti-inflammatory activity due to inhibition of inducible nitric oxide (iNO and prostaglandin E2, via its action on murine macrophages. However, present work evidenced that molecular docking of aloe emodin modulates the anti-inflammatory activity, as well as expression of COX-2 (cyclooxygenase-2 in rodent. The AEC (4,5-dihydroxy-9,10-dioxo-9,10-dihydroanthracene-2 carboxylic acid was synthesized using aloe emodin as starting material. The study was planned for evaluation of possible anti-inflammatory and antiarthritic activity in carrageenan rat induced paw oedema and complete Freund’s adjuvant induced arthritis in rats. The AE (aloe emodin and AEC significantly P<0.001 reduced carrageenan induced paw edema at 50 and 75 mg/kg. Complete Freund’s adjuvant induced arthritis model showed significant P<0.001 decrease in injected and noninjected paw volume, arthritic score. AE and AEC showed significant effect on various biochemical, antioxidant, and hematological parameters. Diclofenac sodium 10 mg/kg showed significant P<0.001 inhibition in inflammation and arthritis.

    Prosopis chilensis is used locally in Sudan for inflammatory conditions of joints; however, literature lacks scientific evidence for anti-inflammatory effect of this plant. To evaluate anti-inflammatory and analgesic effects of prosopis chilenses. Edema inhibition percent (EI %) and hot plate method were used to evaluate anti-inflammatory and analgesic effects of Prosopis chilenses in Wistar albino rats. Anti-inflammatory and analgesic effects of Prosopis chilenses were compared to indomethacin and acetylsalicylic acid respectively. Ethanolic extract of prosopis chilensis at a dose of 200 and 100mg/kg body weight achieved peak EI% (EI% = 96.1%) and (EI% = 94.4%) three and four hours after oral dosing respectively. The maximum EI% for indomethacin was 97.0% and was recorded after 4 hours following oral administration of the drug at a dose of 5 mg/kg body weight. Prosopis chilensis extracts at doses of 100 and 200 mg/kg body weight significantly increased the rats' response time to hot plate compared to acetylsalicylic acid at a dose rate of 100mg/kg body weight (Pprosopis chilenses. Relevance of these effects to prosopis chilenses phy-to-constituents was discussed.

    Babassu oil extraction is the main income source in nut breakers communities in northeast of Brazil. Among these communities, babassu oil is used for cooking but also medically to treat skin wounds and inflammation, and vulvovaginitis. This study aimed to evaluate the anti-inflammatory activity of babassu oil and develop a microemulsion system with babassu oil for topical delivery. Topical anti-inflammatory activity was evaluated in mice ear edema using PMA, arachidonic acid, ethyl phenylpropiolate, phenol, and capsaicin as phlogistic agents. A microemulsion system was successfully developed using a Span® 80/Kolliphor® EL ratio of 6 : 4 as the surfactant system (S), propylene glycol and water (3 : 1) as the aqueous phase (A), and babassu oil as the oil phase (O), and analyzed through conductivity, SAXS, DSC, TEM, and rheological assays. Babassu oil and lauric acid showed anti-inflammatory activity in mice ear edema, through inhibition of eicosanoid pathway and bioactive amines. The developed formulation (39% A, 12.2% O, and 48.8% S) was classified as a bicontinuous to o/w transition microemulsion that showed a Newtonian profile. The topical anti-inflammatory activity of microemulsified babassu oil was markedly increased. A new delivery system of babassu microemulsion droplet clusters was designed to enhance the therapeutic efficacy of vegetable oil. PMID:29430254

    In this study, 44 compounds in the petroleum ether extract of Maqian (Zanthoxylum myriacanthum var. pubescens) bark, a traditional Dai herbal medicine, were identified by GC-MS. Major components included 3(2H)-benzofuranone, asarinin and (dimethoxymethyl)-3-methoxy-benzene. A total of 18 compounds were isolated from the ethyl acetate extracts of Maqian bark by column chromatography and identified by chemical and spectral analyses. Rhoifoline B, zanthoxyline dimethoxy derivative, N-nortidine, nitidine, decarine are the major alkaloids. Both the petroleum ether and ethyl acetate extracts showed significant inhibition on NO production, which imply anti-inflammatory activity, in lipopolysaccharide-induced RAW 264.7 cells without cell toxicity. Decarine is the major anti-inflammatory constituent with NO IC50 values of 48.43 μM on RAW264.7 cells. The petroleum ether extract, the ethyl acetate extract and decarine showed anti-inflammatory activities through inhibiting TNF-α and IL-1β production in lipopolysaccharide-stimulated THP-1 cells without cell toxicity too. Decarine showed anti-inflammatory activity on human colon cells by reducing IL-6 and IL-8 production in TNF-α+IL-1β-induced Caco-2 cells. These results support the use of Maqian bark as a remedy for enteritis and colitis recorded by Dai medicine in China, and elucidate the major pharmacological compounds in Maqian bark. PMID:28383530

    Full Text Available Andrographolide (AG is an abundant component of plants of the genus Andrographis and has a number of beneficial properties including neuroprotective, anticancer, anti-inflammatory, and antidiabetic effects. Despite numerous pharmacological studies, the precise mechanism of AG is still ambiguous. Thus, in the present study, we investigated the molecular mechanisms of AG and its target proteins as they pertain to anti-inflammatory responses. AG suppressed the production of nitric oxide (NO and prostaglandin E2 (PGE2, as well as the mRNA abundance of inducible NO synthase (iNOS, tumor necrosis factor-alpha (TNF-α, cyclooxygenase (COX-2, and interferon-beta (IFN-β in a dose-dependent manner in both lipopolysaccharide- (LPS- activated RAW264.7 cells and peritoneal macrophages. AG also substantially ameliorated the symptoms of LPS-induced hepatitis and EtOH/HCl-induced gastritis in mice. Based on the results of luciferase reporter gene assays, kinase assays, and measurement of nuclear levels of transcription factors, the anti-inflammatory effects of AG were found to be clearly mediated by inhibition of both (1 extracellular signal-regulated kinase (ERK/activator protein (AP-1 and (2 IκB kinase ε (IKKε/interferon regulatory factor (IRF-3 pathways. In conclusion, we detected a novel molecular signaling pathway by which AG can suppress inflammatory responses. Thus, AG is a promising anti-inflammatory drug with two pharmacological targets.

  6. Transgenic Mice Overexpressing Vitamin D Receptor (VDR) Show Anti-Inflammatory Effects in Lung Tissues.

    Vitamin D insufficiency is increasingly recognized as a prevalent problem worldwide, especially in patients with a chronic lung disease. Chronic obstructive pulmonary disease (COPD) is a type of chronic inflammatory lung disease. Previous clinical studies have shown that COPD leads to low vitamin D levels, which further increase the severity of COPD. Vitamin D homeostasis represents one of the most important factors that potentially determine the severity of COPD. Nonetheless, the mechanisms underlying the anti-inflammatory effects of vitamin D receptor (VDR) in lung tissues are still unclear. To investigate the anti-inflammatory effects of VDR, we generated transgenic mice that show lung-specific VDR overexpression under the control of the surfactant protein C promoter (TG mice). The TG mice were used to study the expression patterns of proinflammatory cytokines using real-time polymerase chain reaction and immunohistochemistry. The TG mice had lower levels of T helper 1 (Th1)-related cytokines than wild-type (WT) mice did. No significant differences in the expression of Th2 cytokines were observed between TG and WT mice. This study is the first to achieve lung-specific overexpression of VDR in TG mice: an interesting animal model useful for studying the relation between airway cell inflammation and vitamin D signaling. VDR expression is an important factor that influences anti-inflammatory responses in lung tissues. Our results show the crucial role of VDR in anti-inflammatory effects in lungs; these data are potentially useful for the treatment or prevention of COPD.

    Grewia asiatica Linn. (Family: Tiliaceae), called Phalsa in Hindi is an Indian medicinal plant used for a variety of therapeutic and nutritional uses. The root bark of the plant is traditionally used in rheumatism (painful chronic inflammatory condition). The present study demonstrates the analgesic and anti-inflammatory activity of root bark of G. asiatica in rodents. The methanolic extract of Grewia asiatica (MEGA) and aqueous extract of Grewia asiatica (AEGA) of the bark were prepared and subjected to phytochemical tests and pharmacological screening for analgesic and anti-inflammatory effect in rodents. Analgesic effect was studied using acetic acid-induced writhing in mice and hot plate analgesia in rats while anti-inflammatory activity was investigated using carrageenan-induced paw oedema in rats. The MEGA or AEGA was administered orally in doses of 200 and 400 mg/kg/day of body weight. Data were analysed by one-way analysis of variance followed by Dunnett's test. The extracts showed a significant inhibition of writhing response and increase in hot plate reaction time and also caused a decrease in paw oedema. The effects were comparable with the standard drugs used. The present study indicates that root bark of G. asiatica exhibits peripheral and central analgesic effect and anti-inflammatory activity, which may be attributed to the various phytochemicals present in root bark of G. asiatica.

    The anti-inflammatory and analgesic effects of theacrine (1, 3, 7, 9-tetramethyluric acid), a purine alkaloid which is abundantly present in Camellia kucha, were investigated. Xylene-induced ear edema, acetic acid-induced vascular permeability and lambda-carrageenan-induced paw edema were used to investigate anti-inflammatory activity, and acetic acid-induced writhing and hot-plate tests were used to determine analgesic effect. Oral administration of theacrine (8-32 mg/kg) induced dose-related anti-inflammatory and analgesic effects. On the other hand, oral caffeine administration (8-32 mg/kg) did not show an inhibitory effect on the inhibition of inflammatory response or cause analgesia. Additionally, the result of the acute toxicity test showed that the LD(50) of theacrine was 810.6 mg/kg (769.5-858.0mg/kg). The data obtained suggest theacrine possessed analgesic and anti-inflammatory activities. Crown Copyright (c) 2010. Published by Elsevier B.V. All rights reserved.

    To assess associations between Parkinson disease (PD) and putatively protective factors-smoking, caffeine (coffee, tea, and soft drinks), and nonsteroidal anti-inflammatory drugs (aspirin, ibuprofen, and naproxen). Family-based case-control study. Academic medical center clinic. A total of 356 case subjects and 317 family controls who self-reported environmental exposures. Associations between PD and environmental measures (history, status, dosage, duration, and intensity) of smoking, coffee, caffeine, nonsteroidal anti-inflammatory drugs, and non-aspirin nonsteroidal anti-inflammatory drugs were examined using generalized estimating equations with an independent correlation matrix while controlling for age and sex. Individuals with PD were significantly less likely to report ever smoking (odds ratio = 0.56; 95% confidence interval, 0.41-0.78). Additional measures of smoking revealed significant inverse associations with PD (Pcoffee drinking was inversely associated with PD (test for trend P = .05). Increasing dosage (trend P = .009) and intensity (trend P = .01) of total caffeine consumption were also inversely associated, with high dosage presenting a significant inverse association for PD (odds ratio = 0.58; 95% confidence interval, 0.34-0.99). There were no significant associations between nonsteroidal anti-inflammatory drugs and PD. Inverse associations of smoking and caffeine were corroborated using families with PD, thus emphasizing smoking and caffeine as important covariates to consider in genetic studies of PD.

    textabstractBackground: Chronic back pain is an important health problem. Non-steroidal anti-inflammatory drugs (NSAIDs) are widely used to treat people with low back pain, especially people with acute back pain. Short term NSAID use is also recommended for pain relief in people with chronic back

    Background. The nervous system, through the vagus nerve, can down-regulate inflammation in vivo by decreasing the release of tumor necrosis factor-a by endotoxin-stimulated macrophages. This anti-inflammatory effect is mediated by an interaction between acetylcholine, the principal neurotransmitter

    Colorectal cancer is the second leading cause of cancer death in the U.S.A. Recent research suggests that nonsteroidal anti-inflammatory drugs (NSAIDs) are effective in the prevention of colorectal neoplasia. This review summarises the results of research in animals and humans of these compounds in

    Our study aimed at the identification of anti-inflammatory activities of different fractions of C. sadleriana extract after per os administration in rats, the identification of the active compounds of the plant and the investigation of the in vitro anti-inflammatory activities of Centaurea species native to or cultivated in the Carpathian Basin. The aerial parts of Centaurea sadleriana Janka have been used in Hungarian folk medicine to treat the wounds of sheep. Methanol extract of C. sadleriana was fractioned by solvent-solvent partitioning. The n-hexane fraction was further fractionated and the anti-inflammatory activities of certain subfractions were confirmed in vivo in rats. The n-hexane and chloroform fraction of the methanol extract of C. sadleriana exhibited remarkable COX-1 and COX-2 inhibiting effects in vitro. Chromatographic separation of the fractions led to the identification of the active subfractions and 11 compounds (α-linolenic acid, γ-linolenic acid, stigmasterol, β-sitosterol, campesterol, vanillin, pectolinarigenin, salvigenin, hispidulin, chrysoeriol and apigenin). The in vitro screening for anti-inflammatory activities of further Centaurea species occurring in the Carpathian Basin (C. adjarica, C. bracteata, C. cataonica, C. cynaroides, C. dealbata, C. indurata, C. macrocephala, C. melitensis, C. nigrescens, C. ruthenica) revealed considerable COX-1 and COX-2 inhibitory activities. Because C. sadleriana is an endangered species native only to the Carpathian Basin, the investigation of more prevalent species is reasonable. Copyright © 2012 John Wiley & Sons, Ltd.
