M. C. Souza Abstract Myracrodruon urundeuva Allemão is a plant utilized in Northeast Brazil as an antiinflammatory, wound healing and in gynecological illnesses. The objectives of the present study were to evaluate the antiinflammatory and antiulcer properties of the tannin-enriched fraction (TEF) isolated from the stem bark of M. urundeuva, in the formalin test, in mice, and in carrageenan-induced paw edema and gastric ulcer models, in rats. The results showed that TEF dose-dependently inhibited both phases of the formalin test. However, the effect was predominant in the 2nd phase of the response where inhibitions of 47%, 76% and 85% were observed, with doses of 5, 10 and 50 mg/kg, i.p. In the carrageenan-induced paw edema, significant inhibitions were observed at 3 h (44%) and 4 h (28%), with a dose of 10 mg/kg, i.p. TEF also significantly decreased by 37%, 43% and 57% gastric ulceration induced by indomethacin, at doses of 10, 20 and 50 mg/kg p.o. In the ethanol-induced gastric ulcer model, TEF was less effective, and significant inhibitions (42% to 46%) were observed only with doses of 100 and 200 mg/kg, p.o., respectively. In conclusion, it was shown that TEF presents antiinflammatory and antiulcer effects, partly due to its antioxidant action, known to be present in polyphenols, including tannins.

[source] Antiinflammatory and Anticoagulant Effects of Transgenic Expression of Human Thrombomodulin in MiceAMERICAN JOURNAL OF TRANSPLANTATION, Issue 2 2010S. Crikis Thrombomodulin (TBM) is an important vascular anticoagulant that has species specific effects. When expressed as a transgene in pigs, human (h)TBM might abrogate thrombotic manifestations of acute vascular rejection (AVR) that occur when GalT-KO and/or complement regulator transgenic pig organs are transplanted to primates. hTBM transgenic mice were generated and characterized to determine whether this approach might show benefit without the development of deleterious hemorrhagic phenotypes. hTBM mice are viable and are not subject to spontaneous hemorrhage, although they have a prolonged bleeding time. They are resistant to intravenous collagen-induced pulmonary thromboembolism, stasis-induced venous thrombosis and pulmonary embolism. Cardiac grafts from hTBM mice to rats treated with cyclosporine in a model of AVR have prolonged survival compared to controls. hTBM reduced the inflammatory reaction in the vein wall in the stasis-induced thrombosis and mouse-to-rat xenograft models and reduced HMGB1 levels in LPS-treated mice. These results indicate that transgenic expression of hTBM has anticoagulant and antiinflammatory effects that are graft-protective in murine models.

[source] Immunomodulatory effects of probiotic bacteria DNA: IL-1 and IL-10 response in human peripheral blood mononuclear cellsFEMS IMMUNOLOGY & MEDICAL MICROBIOLOGY, Issue 2 2003Karen Manon Lammers Abstract A new therapeutic approach for inflammatory bowel diseases is based on the administration of probiotic bacteria. Prokaryotic DNA contains unmethylated CpG motifs which can activate immune responses, but it is unknown whether bacterial DNA is involved in the beneficial effects obtained by probiotic treatment. Peripheral blood mononuclear cells (PBMC) from healthy donors were incubated with pure DNA of eight probiotic strains and with total bacterial DNA from human feces collected before and after probiotic ingestion. Cytokine production was analyzed in culture supernatants. Modification of human microflora after probiotic administration was proven by polymerase chain reaction analysis. Here we show that Bifidobacterium genomic DNA induced secretion of the antiinflammatory interleukin-10 by PBMC. Total bacterial DNA from feces collected after probiotic administration modulated the immune response by a decrease of interleukin-1, and an increase of interleukin-10. [source] Functional polymorphism in ALOX15 results in increased allele-specific transcription in macrophages through binding of the transcription factor SPI1 ,HUMAN MUTATION, Issue 1 2006Jonas Wittwer Abstract The reticulocyte-type 15-lipoxygenase-1 (ALOX15) has antiinflammatory and inflammatory effects, and is implicated in the development of asthma, arthritis, and atherosclerosis. We screened the human ALOX15 gene for variations because genetic variability in ALOX15 may influence these diseases. We detected 11 variations, including five polymorphisms located in the ALOX15 promoter region. One of these polymorphisms, a C-to-T substitution at position c.,292, created a novel transcription factor binding site for SPI1. Transcription assays revealed that promoter variants with c.,292 T transcribe twice as efficiently as all the other promoter variants containing c.,292C. This was true in macrophages that constitutively express SPI1, but not in a lung epithelial cell line that does not express SPI1. Mutation of the core-binding site for SPI1 abolished the higher transcriptional activity, and electrophoretic mobility shift assays showed that SPI1 selectively binds to the mutant c.,292 T and c.,292C promoter. These results were corroborated in primary human macrophages, in which macrophages from heterozygous c.,292CT carriers expressed three times more ALOX15 mRNA than macrophages from homozygous c.,292CC carriers. We conclude that the c.,292 T allele in the ALOX15 promoter generates a novel binding site for the transcription factor SPI1 that results in higher transcription of the gene in macrophages. This may lead to an increase in ALOX15-mediated lipid metabolites, which play a role in inflammation. Hum Mutat 27(1), 78,87, 2006. © 2005 Wiley-Liss, Inc. [source] Asiatic acid, a pentacyclic triterpene from Centella asiatica, is neuroprotective in a mouse model of focal cerebral ischemiaJOURNAL OF NEUROSCIENCE RESEARCH, Issue 11 2009Rajanikant G. Krishnamurthy Abstract Asiatic acid, a triterpenoid derivative from Centella asiatica, has shown biological effects such as antioxidant, antiinflammatory, and protection against glutamate- or ,-amyloid-induced neurotoxicity. We investigated the neuroprotective effect of asiatic acid in a mouse model of permanent cerebral ischemia. Various doses of asiatic acid (30, 75, or 165 mg/kg) were administered orally at 1 hr pre- and 3, 10, and 20 hr postischemia, and infarct volume and behavioral deficits were evaluated at day 1 or 7 postischemia. IgG (blood,brain barrier integrity) and cytochrome c (apoptosis) immunostaining was carried out at 24 hr postischemia. The effect of asiatic acid on stress-induced cytochrome c release was examined in isolated mitochondrial fractions. Furthermore, its effects on cell viability and mitochondrial membrane potential were studied in HT-22 cells exposed to oxygen-glucose deprivation. Asiatic acid significantly reduced the infarct volume by 60% at day 1 and by 26% at day 7 postischemia and improved neurological outcome at 24 hr postischemia. Our studies also showed that the neuroprotective properties of asiatic acid might be mediated in part through decreased blood,brain barrier permeability and reduction in mitochondrial injury. The present study suggests that asiatic acid may be useful in the treatment of cerebral ischemia. © 2009 Wiley-Liss, Inc. [source] Estrogen attenuated markers of inflammation and decreased lesion volume in acute spinal cord injury in ratsJOURNAL OF NEUROSCIENCE RESEARCH, Issue 2 2005Eric Anthony Sribnick Abstract Spinal cord injury (SCI) is a devastating neurologic injury with functional deficits for which the only currently recommended pharmacotherapy is high-dose methylprednisolone, which has limited efficacy. Estrogen is a multiactive steroid that has shown antiinflammatory and antioxidant effects, and estrogen may modulate intracellular Ca2+ and attenuate apoptosis. For this study, male rats were divided into three groups. Sham group animals received a laminectomy at T12. Injured rats received both laminectomy and 40 g · cm force SCI. Estrogen-group rats received 4 mg/kg 17,-estradiol (estrogen) at 15 min and 24 hr post-injury, and vehicle-group rats received equal volumes of dimethyl sulfoxide (vehicle). Animals were sacrificed at 48 hr post-injury, and 1-cm-long segments of the lesion, rostral penumbra, and caudal penumbra were excised. Inflammation was assessed by examining tissue edema, infiltration of macrophages/microglia, and levels of cytosolic and nuclear NF,B and inhibitor of kappa B (I,B,). Myelin integrity was examined using Luxol fast blue staining. When compared to sham, vehicle-treated animals revealed increased tissue edema, increased infiltration of inflammatory cells, decreased cytosolic levels of NF,B and I,B,, increased levels of nuclear NF,B, and increased myelin loss. Treatment of SCI rats with estrogen reduced edema and decreased inflammation and myelin loss in the lesion and penumbral areas, suggesting its potential as a therapeutic agent. Further work needs to be done, however, to elucidate the neuroprotective mechanism of estrogen. © 2005 Wiley-Liss, Inc.

Foppoli Abstract NCX4016 [2-acetoxybenzoic acid 3,-(nitrooxymethyl)phenyl ester] is a recently developed nitrooxy-derivative of aspirin with improved antiinflammatory, analgesic, and antithrombotic activity as well as increased gastrointestinal safety. Systematic polymorphic screening performed with different solvents and preparation methods resulted in the identification of two polymorphs, designated Forms I and II. They were characterized by scanning electron microscopy, powder X-ray diffraction, thermal analyses, and infrared spectroscopy; the crystal structure of polymorph I was solved by single-crystal X-ray analysis and compared with that of aspirin. Finally, intrinsic dissolution rate studies and calculations according to the melting data method were performed to assess the thermodynamic relationship between the two polymorphs. © 2004 Wiley-Liss, Inc. and the American Pharmacists Association J Pharm Sci 93:521,531, 2004 [source] The mechanisms of tumor suppressor effect of glucocorticoid receptor in skinMOLECULAR CARCINOGENESIS, Issue 8 2007Dmitry Chebotaev Abstract Glucocorticoid hormones exert a tumor suppressor effect in different experimental models, including mouse skin carcinogenesis. The glucocorticoid control of cellular functions is mediated via the glucocorticoid receptor (GR), a well-known transcription factor that regulates genes by DNA-binding dependent transactivation, and DNA-binding independent transrepression through negative interaction with other transcription factors. In this perspective, we analyze known mechanisms that underlie the anticancer effect of GR signaling, including effects on cell growth, differentiation, apoptosis, and angiogenesis. We also discuss a novel mechanism for the tumor suppressor effect of the GR in skin: through the regulation of the number and status of follicular epithelial stem cells (SC), which are a target cell population for skin carcinogenesis. Our studies on keratin5.GR transgenic animals that are resistant to skin carcinogenesis, demonstrated that the GR diminishes the number of follicular epithelial SCs, reduces their proliferative and survival potential and affects the expression of follicular SC "signature" genes. The analysis of global effect of the GR on gene expression in follicular epithelial SCs, basal keratinocytes, and mouse skin tumors provided an unexpected evidence that gene transrepression by GR plays an important role in the maintenance of SC and in inhibition of skin carcinogenesis by this steroid hormone receptor. It is known that antiinflammatory effect of glucocorticoids is chiefly mediated by GR transrepression. Thus, our findings suggest the similarity between the mechanisms of antiinflammatory and anticancer effects of the GR signaling. We discuss the potential clinical applications of our findings in light of drug discovery programs focused on the development of selective GR modulators that preferentially induce GR transrepression. © 2007 Wiley-Liss, Inc. [source] Inflammation and remodeling in the adult and child with asthmaPEDIATRIC PULMONOLOGY, Issue S21 2001Peter Jeffery MSc Abstract Inflammation and remodeling are characteristic features of the conducting airways in asthma, but the relationships between inflammation, inappropriate remodeling, bronchial hyperresponsiveness, and reduced pulmonary function are still unclear. In both adults and children with asthma, there are structural changes of the conducting airways that include injury and loss of the surface epithelium, thickening of the reticular basement membrane, increases of underlying collagen, blood vessels, and airway smooth muscle, and plugging of the airways by exudate. Bronchial biopsies obtained from persons with mild stable asthma already demonstrate the presence of inflammation. Many of the inflammatory and structural changes begin early in childhood. Whereas corticosteroids markedly reduce many aspects of inflammation, it is not known whether and how they affect the changes associated with airway wall remodeling. Leukotriene receptor antagonists appear to be antiinflammatory and able to reduce the proliferation of bronchial smooth muscle. Pediatr Pulmonol. 2001; Supplement 21:3,16. © 2001 Wiley-Liss, Inc. [source] Antioxidant and cytoprotective properties of infusions from leaves and inflorescences of Achillea collina Becker ex Rchb.PHYTOTHERAPY RESEARCH, Issue 4 2009Annamaria Giorgi Abstract Plants are the main source of molecules with antioxidant and radical scavenging properties that aid the natural defence systems of cells and may be involved in the preservation of human health, particularly preventing all the physiopathological conditions where oxidative damage is a hallmark. Achillea collina Becker ex Rchb. is a medicinal plant of the Achillea millefolium aggregate (yarrow) traditionally used, particularly in mountain areas, as an infusion or alcohol extract for its digestive, antiinflammatory, analgesic, antipyretic and wound healing properties. The aim of this study was to investigate the antioxidant capacity and cytoprotective activity against oxidative stress of infusions obtained from the leaves and inflorescences of Achillea collina Becker ex Rchb., assessed by chemical (free radical scavenging activity by DPPH and Folin Ciocalteu assay) and biological assays (in vitro model of cytotoxicity and lipid peroxidation in PC12 cells line). Infusions of leaves had the highest antioxidant properties and cytoprotective activity. The antioxidant capacity was significantly correlated with the total phenolic content but not with the cytoprotective profile. Achillea collina Becker ex Rchb. has good antioxidant and cytoprotective properties, suggesting further investigations on its chemical composition and potential health value, particularly for traditionally prepared infusions of leaves.

[source] Antioxidant and antiinflammatory activities of Sideritis perfoliata subsp. perfoliata (Lamiaceae)PHYTOTHERAPY RESEARCH, Issue 4 2008Maria-Thiresia Charami Abstract Sideritis perfoliata L. subsp. perfoliata is a plant widely used in folk medicine in Greece since antiquity because of its antiinflammatory, antirheumatic, antiulcer, digestive and vasoprotective properties. Phytochemical investigations of the polar extracts afforded four flavonoid glycosides, four phenylpropanoic glycosides, caffeic acid and one iridoid, ajugoside. Reactive oxygen species (ROS) are implicated in the aetiology of several inflammatory processes. In the present study polar fractions and isolated compounds from S. perfoliata subsp. perfoliata were evaluated for their antioxidant activity using DPPH spectrophotometric and TBA lipid peroxidation assays, as well as for their antiinflammatory activity using the soybean lipoxygenase bioassay. All extracts and isolated compounds showed significant antioxidant and inhibitory activity against soybean lipoxygenase. These findings give support to the ethnopharmacological use of the plant in the treatment of several inflammatory ailments. Copyright © 2008 John Wiley & Sons, Ltd. [source] A 90 day repeated oral toxicity study on plantamajoside concentrate from Plantago asiaticaPHYTOTHERAPY RESEARCH, Issue 12 2007Byung-Gyu Park Abstract Plantago asiatica is distributed widely in East Asia. Since ancient times it has been used as a diuretic to treat acute urinary infections, and as an antiinflammatory, antiasthmatic, antioxidant, antibacterial, antihyperlipidemic and antihepatitis drug. The major compound, plantamajoside from P. asiatica, which is used as a marker compound in chemotaxonomic studies, was reported to have antibacterial activity, inhibition activity against cAMP phosphodiesterase and 5-lipoxygenase and antioxidant activity. However, there are no reports on the safety of plantamajoside. This study assessed the toxic effects of plantamajoside concentrate (PC), the purity of which was above 80%, in rats following administration at dose levels of 0, 500, 1000 and 2000 mg/kg body weight/day for 13 weeks, as recommended by the OECD guidelines. The results showed that there were no differences in body weight, food intake, water consumption, relative organ weight or the hematological and serum biochemical values among the different dosage groups. No death or abnormal clinical signs were observed during the experimental period. Therefore, the results suggested that no observed adverse effect level (NOAEL) of the PC in rats after oral administration is considered to be greater than 2000 mg/kg in rats under the conditions employed in this study.

[source] Effects of thymoquinone (volatile oil of black cumin) on rheumatoid arthritis in rat modelsPHYTOTHERAPY RESEARCH, Issue 9 2007Ibrahim Tekeoglu Abstract Many studies have been carried out in recent years on the pharmacological effects of Nigella sativa seeds that have uncovered their antiinflammatory and immunological effects. The objective of this study was to explore the antiinflammatory effects of thymoquinone on arthritis in rat models. Rats with arthritis induced by Freund's incomplete adjuvant were assigned to five groups: group 1: controls 0.9% NaCl (n = 7); group 2: 2.5 mg/kg thymoquinone (n = 7); group 3: 5 mg/kg thymoquinone (n = 7); group 4: Bacilli Chalmette Guerin (BCG) 6 × 105 CFU (n = 7); group 5: methotrexate 0.3 mg/kg (n = 7). Signs of inflammation on the claw and radiological signs were searched for and TNF-alpha and IL-1beta were measured. The results of the control and other groups were compared. As a result, thymoquinone, confirmed clinically and radiologically, suppressed adjuvant-induced arthritis in rats. Copyright © 2007 John Wiley & Sons, Ltd. [source] Analgesic and antiinflammatory activity of Cyclamen repandum S. et S.PHYTOTHERAPY RESEARCH, Issue 7 2007E. Speroni Abstract According to folk medicine some species belonging to the genus Cyclamen were used for their biological activities. Early investigation of the different species of the genus resulted in the isolation of triterpenic saponins. No phytochemical and biological data are available on C. repandum. As part of a series of phytochemical investigations for bioactive compounds from medicinal plants, Cyclamen repandum S. et S. was investigated. The present study sought to find the antiinflammatory and antinociceptive activities of C. repandum tubers in rats and mice. A preliminary screening was conducted with three different extracts in the tests used, particularly the paw edema and the writhing tests. Subsequently some saponins isolated from the ME extract, the more effective one, have been identified. This paper also describes the results of fractionation and bioassay guided chemical studies. Chemical investigation of the active extract afforded the isolation and characterization of six triterpenic saponins. The possible antiinflammatory and analgesic properties were investigated as the saponin content of the fractions allows to speculate on such aspect. Copyright © 2007 John Wiley & Sons, Ltd.

However, the effect was predominant in the 2nd phase of the response where inhibitions of 47%, 76% and 85% were observed, with doses of 5, 10 and 50 mg/kg, i.p. In the carrageenan-induced paw edema, significant inhibitions were observed at 3 h (44%) and 4 h (28%), with a dose of 10 mg/kg, i.p. TEF also significantly decreased by 37%, 43% and 57% gastric ulceration induced by indomethacin, at doses of 10, 20 and 50 mg/kg p.o. In the ethanol-induced gastric ulcer model, TEF was less effective, and significant inhibitions (42% to 46%) were observed only with doses of 100 and 200 mg/kg, p.o., respectively. In conclusion, it was shown that TEF presents antiinflammatory and antiulcer effects, partly due to its antioxidant action, known to be present in polyphenols, including tannins.

Singh Abstract A 95% ethanol extract from whole aerial parts of Euphorbia hirta (EH A001) showed antihistaminic, antiinflammatory and immunosuppressive properties in various animal models. EH A001 inhibited rat peritoneal mast cell degranulation triggered by compound 48/80. It significantly inhibited dextran-induced rat paw edema. EH A001 prevented eosinophil accumulation and eosinophil peroxidase activity and reduced the protein content in bronchoalveolar lavage fluid (BALF) in a ,mild' model of asthma. Moreover, the CD4/CD8 ratio in peripheral blood was suppressed. EH A001 attenuated the release of interleukin-4 (IL-4) and augmented interferon- , (IFN- ,) in ovalbumin-sensitized mouse splenocytes. The results were compared with the effects of known compounds, ketotifen, cetirizine and cyclophosphamide. These findings demonstrated that Euphorbia hirta possessed significant activity to prevent early and late phase allergic reactions. Copyright © 2006 John Wiley & Sons, Ltd. [source] | ||||||||||||||||
