RESUMO
OBJECTIVES: The aim of the present work was to study the anti-inflammatory and anti-arthritic activities of petroleum ether extract of fenugreek seeds. MATERIALS AND METHODS: Fenugreek seed powder was extracted in petroleum ether by cold maceration. This fenugreek seed petroleum ether extract (FSPEE) was analyzed by gas-liquid chromatography (GLC) and tested on rats against carrageenan and formaldehyde-induced paw edema, complete Freund's adjuvant (CFA)-induced arthritis and cotton pellet-induced granuloma. Changes in serum glutamic oxaloacetic tansaminase (SGOT), serum glutamate-pyruvate transaminase (SGPT), and alkaline phosphatase (ALP) activities in liver and serum were also studied in cotton pellet-induced arthritic rats. Data were analyzed by Student's t-test. P <0.05 was considered statistically significant. RESULTS: GLC of FSPEE showed oleic (33.61%), linoleic (40.37%), and linolenic (12.51%) acids. With 0.5 mL/kg FSPEE treatment, there was 37% (P < 0.05) and 85% (P < 0.05) reduction in inflammation of the paw in carrageenan and formaldehyde-induced paw edema. In CFA-induced arthritis, a biphasic increase in paw volume followed by decrease was seen. There was 42.5% (P < 0.01) reduction in the weight of cotton pellets and significant (P < 0.01) reductions in the elevated SGPT and ALP activities in serum and liver of FSPEE (0.5 mL/kg) treated rats. CONCLUSION: Thus, petroleum ether extract of fenugreek seeds has significant anti-inflammatory and anti-arthritic activities which are due to the presence of linolenic and linoleic acids.

Picrorhiza kurroa is an important medicinal plant in the Ayurvedic system of medicine. The root and rhizome of this plant are used for the treatment of various liver and inflammatory conditions. In the present study, we sought to investigate the anti-inflammatory activity of P. kurroa rhizome extract against carrageenan-induced paw edema and cotton pellet implantation-induced granuloma formation in rats. In addition, its immunomodulatory activity was evaluated in Complete Freund's Adjuvant-induced stimulation of a peritoneal macrophage model and lipopolysaccharide-stimulated RAW 264.7 murine macrophages. Pretreatment with P. kurroa rhizome extract inhibited carrageenan-induced paw edema and cotton pellet-induced granuloma formation in a dose-dependent manner. This was associated with reduced levels of inflammatory cytokines (TNF-α, IL-1ß, IL-6) accompanied with increased anti-inflammatory cytokine (IL-10) in the serum and peritoneal macrophages. Additionally, P. kurroa rhizome extract inhibited inflammatory TNF-receptor 1 and cyclooxygenase-2 in Complete Freund's Adjuvant-induced activated peritoneal macrophages. Furthermore, P. kurroa rhizome extract treatment significantly inhibited iNOS and suppressed the activation of NF-κB through inhibition of its phosphorylation and by blocking the activation of IκB kinase alpha in lipopolysaccharide-stimulated RAW264.7 macrophages. Taken together, these results suggest that P. kurroa has anti-inflammatory activity that is mediated through the suppression of macrophage-derived cytokine and mediators via suppression of NF-κB signaling.

ETHNOPHARMACOLOGICAL RELEVANCE: Jungia rugosa Less (Asteraceae), popularly known in Ecuador as "Carne humana" or "Fompo", is a vine present into the Andean region. It is traditionally used as medicine for the treatment of bruises, cuts and other external inflammatory processes. This study was designed to investigate the anti-inflammatory activity of J. rugosa leaves extract (JRLE) in rodents. MATERIAL AND METHODS: The acute anti-inflammatory activity was evaluated by animal models, including croton oil-induced ear oedema in mice, carrageenan-induced paw oedema in rats and myeloperoxidase (MPO); the chronic anti-inflammatory activity was evaluated by cotton pellet-induced granuloma. RESULTS: Intraperitoneal administration of JRLE (125, 250, 500mg/kg) significantly (p<0.01-0.001) inhibited the croton oil-induced ear oedema and MPO activity in mice; the carrageenan-induced paw oedema in rats was significantly (p<0.05) reduced by 500mg/kg. Repeated (6 days) administration of the extract to mice previously implanted with cotton pellets reduced the formed granuloma (125mg/kg: 11.7%; 250mg/kg: 17.9%; 500mg/kg: 32.4%) but only the inhibition by 500mg/kg reached statistical significance (p<0.01). CONCLUSIONS: The results show that JRLE is effective as an anti-inflammatory agent in acute and chronic inflammation in mice, supporting its traditional use.

AIM OF THE STUDY: Arrabidaea brachypoda (DC.) Bureau has been used to relieve general pain, painful joints and kidney stones in Brazilian folk medicine. Nevertheless, scientific information regarding this species is scarce; there are no reports related to its possible analgesic and anti-inflammatory effects. This study was aimed at evaluating the traditional use of Arrabidaea brachypoda root using in vivo inflammatory and nociceptive models. MATERIALS AND METHODS: Carrageenan-induced paw edema, peritonitis and fibrovascular tissue growth induced by s.c. cotton pellet implantation were used to investigate the anti-inflammatory activity of Arrabidaea brachypoda roots ethanolic extract (AbEE) in rats. Formalin and acetic acid-induced writhing tests were used to investigate the antinociceptive activity in mice. High-performance liquid chromatography (HPLC) was used to determine the fingerprint chromatogram of AbEE. RESULTS: The AbEE at test doses of 30-300 mg/kg p.o. demonstrated anti-inflammatory effects. AbEE reduced paw edema induced by carrageenan, inhibited leukocyte recruitment into the peritoneal cavity and, in the model of chronic inflammation using the cotton pellet-induced fibrovascular tissue growth in rats, significantly inhibited the formation of granulomatous tissue. The extracts at test doses of 30-300 mg/kg p.o. clearly demonstrated antinociceptive activity, except during the first phase of the formalin test. The presence of quercetin and phenolic compounds in the extract Arrabidaea brachypoda was confirmed using HPLC. CONCLUSION: Arrabidaea brachypoda ethanol extract markedly demonstrated anti-inflammatory action in rats and antinociceptive activity in mice, which supports the previous claims of traditional use.

CONTEXT: The leaf of sage Salvia officinalis L. (Lamiaceae) is reputed in the folk medicine of Arabia, and Jordan in particular, to relieve pain associated with gastrointestinal disturbance. OBJECTIVES: Evaluation of the antinociceptive and anti-inflammatory activities of aqueous and butanol extracts of S. officinalis leaf. MATERIALS AND METHODS: The analgesic effects of the aqueous extract (10, 31.6, 100, 316, 1000 mg/kg) and butanol extract (10, 31.6, 100, 316 mg/kg) were studied using the hot-plate test for mice and the formalin-induced paw licking in rats. The effects were compared to those of morphine and the influence of naloxone on these effects was also evaluated. The same concentrations of both extracts were used to evaluate their anti-inflammatory effects using the cotton pellet granuloma and carrageenan-induced paw edema in rats. RESULTS: The aqueous extract (10, 31.6, 100, 316, 1000 mg/kg) and butanol extract (10, 31.6, 100, 316 mg/kg) caused analgesic effect in the hot-plate latency assay as well as in early and late phases of formalin-induced paw licking in rats. These effects were reduced by the opioid receptor antagonist, naloxone (5 mg/kg). The same range of doses of both extracts caused dose-dependent inhibition of carrageenan-induced paw edema in rats as well as inhibition of cotton pellet granuloma. DISCUSSION AND CONCLUSION: These observations suggest that the sage leaf aqueous and butanol extracts have analgesic and anti-inflammatory effects, confirming the traditional use of this plant for pain alleviation.

CASE DESCRIPTION: A 6-year-old spayed female Miniature Dachshund was examined because of a 3-day history of anorexia and diarrhea. CLINICAL FINDINGS: A lump was detected during abdominal palpation. Biochemical abnormalities included increases in serum concentrations of total protein, globulin, and C-reactive protein (CRP). Abdominal radiography and abdominal ultrasonography revealed a mass on the caudal aspect of the right kidney. Exploratory laparotomy confimed the mass; however, it could not be excised because it was strongly adhered to surrounding tissues. Histologic examination of a tissue sample from the mass led to a diagnosis of pyogranuloma. TREATMENT AND OUTCOME: The dog was treated with rosuvastatin, but no improvement was evident. Administration of a high dose of prednisolone (1 mg/kg [0.45 mg/lb], PO, q 12 h) was initiated. The CRP concentration returned to within reference limits, and the mass gradually decreased in size. The prednisolone dosage was tapered to 0.14 mg/kg (0.064 mg/lb), PO, every 12 hours. However, once the low dosage of prednisolone was reached, CRP concentration and size of the mass increased. Rosuvastatin was subsequently combined with the low dosage of prednisolone. After 1 week of the combination treatment, the CRP concentration returned to within reference limits, and the mass was reduced in size. The mass eventually could not be detected ultrasonographically. CLINICAL RELEVANCE: A low dose of prednisolone was not effective against the pyogranuloma. However, administration of a low dose of prednisolone in combination with rosuvastatin caused decreases in CRP concentration and size of the pyogranuloma. Thus, statins may act as immunosuppressants.

ETHNOPHARMACOLOGICAL RELEVANCE: Sonchus oleraceus L. has been used to relieve headaches, general pain, hepatitis, infections, inflammation and rheumatism in Brazilian folk medicine. Nevertheless, scientific information regarding this species is scarce; there are no reports related to its possible anti-inflammatory effects. AIM OF THE STUDY: This study was aimed at evaluating the scientific basis for the traditional use of Sonchus oleraceus using in vivo inflammatory models. MATERIALS AND METHODS: Carrageenan-induced paw edema, peritonitis and febrile response induced by lipopolysaccharide tests, as well as fibrovascular tissue growth induced by s.c. cotton pellet implantation were used to investigate the anti-inflammatory activity of Sonchus oleraceus hydroethanolic extract (SoHE) in rats. RESULTS: The SoHE at test doses of 100-300 mg/kg p.o. clearly demonstrated anti-inflammatory effects by reduced paw edema induced by carragenan, inhibited leukocyte recruitment into the peritoneal cavity and reduced LPS-induced febrile response, and in the model of chronic inflammation using the cotton pellet-induced fibrovascular tissue growth in rats, the SoHE significantly inhibited the formation of granulomatous tissue. The extract administered at 300 mg/kg p.o. had a stronger anti-inflammatory effect than indomethacin (10mg/kg) or dexamethasone (1mg/kg). CONCLUSION: The hydroethanolic extract of Sonchus oleraceus markedly demonstrated anti-inflammatory action in rats, which supports previous claims of its traditional use.

This study was designed to evaluate the efficacy of focal hyperthermia and rifampin in vitro and in vivo using a rabbit model of foreign-body infection by methicillin-resistant Staphylococcus aureus (MRSA). In vitro studies demonstrated bacterial re-growth and development of rifampin resistance after 24 h with rifampin alone, which was prevented under hyperthermic conditions. For the in vivo studies, rifampin was administered intraperitoneally every 12 h for 7 days to rabbits with MRSA-containing cages implanted into their flanks. When combined with hyperthermia at 39 degrees C, 41 degrees C and 43 degrees C, rifampin significantly reduced in-cage bacterial counts by > 3.0 log(10) colony forming units/ml compared with rifampin alone. Eradication of cage-associated infection was achieved more effectively when rifampin was combined with hyperthermia, with cure rates of 70-95% on day 10. Focal hyperthermia combined with rifampin prevented the emergence of rifampin resistance and maintained rifampin efficacy. These findings might have implications for orthopaedic surgery.

Methanolic extract of Butea monosperma flowers (MEBM) was studied for anti-inflammatory activity against carrageenin induced paw edema and cotton pellet granuloma in albino rats. In carrageenin induced paw edema, MEBM at oral doses of 600 mg/kg and 800 mg/kg, dose-dependently inhibited the paw edema. In cotton pellet induced granuloma, MEBM at the same doses was found to significantly inhibit granuloma tissue formation, including significant reduction in levels of serum lysosomal enzymes (SGOT, SGPT and ALP) and lipid peroxides as compared to control.

Blueberries are among the edible fruits that are recognized best for their potential health benefits. The crude extract from Vaccinium corymbosum was assessed in anti-inflammatory and antinociceptive models. The crude hydroalcoholic extract was administered orally at doses of 100, 200 or 300 mg kg (-1) for all the assays. In the carrageenan test, the crude extract reduced rat paw oedema by 9.8, 28.5 and 65.9%, respectively. For the histamine assay, the reductions of oedema were 70.1, 71.7 and 81.9%, respectively. In the myeloperoxidase (MPO) assay, 300 mg kg (-1) crude extract produced a significant inhibition of the MPO activity, at 6 h and 24 h after injection of carrageenan, by 42.8 and 46.2%, respectively. With the granulomatous tissue assay dexamethasone displayed significant activity, whereas the blueberry extract was inactive. For the abdominal constriction test, inhibitions of 49.0, 54.5, 53.5%, respectively, were observed for the crude extract, and 61.4% for indometacin. In the formalin test, the crude extract (200 and 300 mg kg (-1)) and indometacin inhibited only the second phase by 36.2, 35.3 and 45.8%, respectively. Considering that the crude extract of blueberry displayed antinociceptive and anti-inflammatory activity, its consumption may be helpful for the treatment of inflammatory disorders.

Austroplenckia populnea (Reiss) Lund is a Brazilian plant from "cerrado", which belongs to Celastraceae family, popularity know as "marmelinho-do campo, mangabeira-brava, mangabarana, vime and maria-mole". This plant is used in folk medicine to treat dysenteries and inflammatory disorders, such as rheumatism. Austroplenckia populnea bark hydroalcoholic crude extract, and its hexane, chloroform and ethyl acetate fractions, obtained by partition, as well as the isolated populnoic acid were investigated for their anti-inflammatory (carrageenan, dextran and histamine-induced rat paw oedema, histamine-induced increase in vascular permeability, and granulomatous tissue induction) and analgesic activities (writhing and hot plate tests). The ED(50) (oral) of the crude extract for the inhibition of carragenan-induced rat paw oedema assay was determined to be 200 mg/kg, which was also used in the assays with the extract and its fractions in all other experiments. Populnoic acid was administered in the dose of 50 mg/kg. Crude extract, hexane and chloroform fractions (200 mg/kg), and indomethacin (10 mg/kg) inhibited significantly (p<0.05) the formation of the carrageenan-induced rat paw oedema, measured in third hour of experiment (peak of oedema formation) by 43.2%, 37.3%, 31.1% and 59.3%, respectively. There was a significant reduction (p<0.05) in dextran-induced rat paw oedema in all groups, while in the assay using histamine as the oedematogenic agent, only the groups treated with populnoic acid (50 mg/kg) and cyproheptadine (10 mg/kg) displayed significant reduction (p<0.05). The populnoic acid and cyproheptadine reduced the peak of oedema formation (1st hour) by 41.3% and 34.7%, respectively. Only for the groups treated with populnoic acid (50 mg/kg) and cyproheptadine (10 mg/kg) it was observed a significant (p<0.05) reduction in histamine-induced increase in vascular permeability (44.8% and 80.3%, respectively). Granulomatous tissue formation was significantly inhibited (p<0.05) by both hexane fraction (46.0%) and dexamethasone (66.2%). In the analgesic assays, the crude extract and its hexane and chloroform fractions, as well as indomethacin diminished significantly the number of writhings (p<0.05) by 69.6%, 47.2%, 44.8% and 62.8%, respectively. On the other hand, none assayed sample displayed significant result in the hot plate test. Based on the obtained results it is suggested that extracts of Austroplenckia populnea bark and populnoic acid display anti-inflammatory activity, supporting its folkloric use to treat inflammatory disorders.

BACKGROUND: Poly-L-lactic acid gained U.S. Food and Drug Administration approval for use in human immunodeficiency virus-related facial lipoatrophy in August of 2004. Since that time, it has become available for use in the United States for human immunodeficiency virus facial lipoatrophy patients and for off-label uses in other areas for soft-tissue contouring. This article is intended to enumerate reconstitution, injection techniques, management, and avoidance of complications. METHODS: The authors have pooled their experiences to arrive at a consensus opinion for recommendations on treatment protocols for injectable poly-L-lactic acid use. RESULTS: This article prescribes techniques to achieve safer, consistent results while minimizing risks of complications with injectable poly-L-lactic acid. Although the product has been used widely in Europe since 1999, physicians in the United States have only recently begun to explore the uses of Sculptra as a volumizing agent in the face and the body. U.S. physicians have benefited from the European experience with this product, including early problems secondary to overaggressive use, low-volume reconstitution, higher volume injection of product at one session, and inadequate time between injection sessions. CONCLUSIONS: The authors therefore have opted for a more conservative approach in their treatment recommendations. Higher volume dilution (8 to 12 cc), fewer vials used at each session, injections placed in the subcutaneous plane without any product being placed in the dermis, adequate time between injection sessions (at least 6 weeks), and postinjection patient massage should decrease the risks and avoid the potential complications associated with poly-L-lactic acid soft-tissue augmentation.

All fillers are associated with the risk of both early and late complications. Early side effects such as swelling, redness, and bruising occur after intradermal or subdermal injections. The patient has to be aware of and accept these risks. Adverse events that last longer than 2 weeks can be attributable to technical shortcomings (e.g., too superficial an implantation of a long-lasting filler substance). Such adverse events can be treated with intradermal 5-fluorouracil, steroid injections, vascular lasers, or intense pulsed light, and later with dermabrasion or shaving. Late adverse events also include immunologic phenomena such as late-onset allergy and nonallergic foreign body granuloma. Both react well to intralesional steroid injections, which often have to be repeated to establish the right dose. Surgical excisions shall remain the last option and are indicated for hard lumps in the lips and visible hard nodules or hard granuloma in the subcutaneous fat.

BACKGROUND: The methanol extract of Ophirrhiza nicobarica, Alstonia macrophylla and Mallotus peltatus, ethnomedicines of Little Andaman, were investigated for antiinfective, antiinflammatory and antioxidant activities. METHODS: Toxicity was determined in cells and in an animal model. Antiviral, antibacterial and antifungal activity was determined by plaque reduction, disc diffusion and agar dilution methods. The antiinflammatory and antioxidant activities were also studied. RESULTS: O. nicobarica at 300 microg ml(-1) showed anti-HSV activity while M. peltatus and A. macrophylla showed antibacterial activity at 64-1,000 microg ml(-1). Both extracts showed significant dose-dependent antiinflammatory and antioxidant activity at nontoxic concentrations. CONCLUSION: The alkaloid, flavonoid and beta-sitosterol isolated from bioactive parts had a dose-dependent therapeutic efficacy, justifying their use. Further study is required to know the mechanism of action.

The chloroform extract of Trichodesma indicum root has been evaluated for anti-inflammatory activity against oedema produced by carrageenan, dextran, histamine and serotonin, and against formation of granulation tissues by cotton pellet in rats. The effect was compared with the activity of indomethacin, cyperoheptadine and dexamethasone against different types of inflammation. The chloroform extract at doses of 50, 100 and 200 mg/kg exhibited significant (P < 0.001) anti-inflammatory activity in acute and chronic inflammatory models. At 200 mg/kg the chloroform extract showed maximum inhibition of 48.12% in carrageenan-induced rat paw oedema while the standard indomethacin inhibited it by 54.32% after 3 h of carrageenan injection. The chloroform extract (50, 100 and 200 mg/kg) significantly (P < 0.001) and dose-dependently inhibited dextran, histamine and serotonin-induced rat paw oedema compared with control group (vehicle-treated). In the chronic inflammatory model, the chloroform extract (100 and 200 mg/kg) inhibited the granuloma weight by 15.42 and 21.12%, respectively, whereas the indomethacin and dexamethasone inhibited it by 29.29 and 34.13%, respectively. The results obtained suggest marked anti-inflammatory activity of the extract at the dose levels examined.

This study evaluated the antiinflammatory activities of pinitol and glucosamine either alone or in combination against carrageenan- and cotton pellet-induced acute and subacute inflammation in rats. Five groups were included in each of the acute and subacute inflammation studies: the vehicle control group, positive control group (aminopyrine 100 mg/kg), pinitol group (20 mg/kg), glucosamine group (25 mg/kg) and a pinitol (20 mg/kg) and glucosamine (25 mg/kg) combination group. When 20 mg/kg of pinitol was administered to the rats, paw edema induced by the carrageenan injection was significantly suppressed and the level of granuloma formation induced by the cotton pellet implantation was slightly reduced. When 25 mg/kg of glucosamine was administered, paw edema caused by the acute inflammation was slightly reduced and the level of granuloma formation caused by the subacute inflammation was strongly suppressed. Although the combined application of pinitol and glucosamine did not have an additional antiinflammatory effect on the paw edema caused by acute inflammation, it did have an increased antiinflammatory effect on the formation of granuloma induced by subacute inflammation. Therefore, pinitol and glucosamine have an antiinflammatory effect on acute and subacute conditions. Moreover, a synergistic antiinflammatory effect against subacute inflammation was observed when the two chemicals were administered in combination.

The oleoresin of several Copaifera species is used widely in the Amazonian Region mainly as a topical antiinflammatory and healing agent. The topical analgesic and antiinflammatory activities of Copaifera duckei oleoresin, whose terpenoidal chemical composition has been characterized, are now examined. Antiinflammatory activity was evaluated in rats using the carrageenin-induced paw edema and the granuloma tests, and in mice by the croton oil-induced dermatitis test. Analgesic activity was determined in mice using the writhing test method. In the carrageenin-induced edema and granuloma tests the oleoresin in a dose of 1,802 mg/kg inhibited the edema by 18% and granuloma by 42% (p < 0.05), this last result similar to that observed with dexamethasone. Topical doses of 517 mg/kg, 1,035 mg/kg and 1,802 mg/kg produced 52%, 58% and 62% (p < 0.05) reduction of the edema induced by croton oil, respectively, and 48%, 56% and 65% inhibition of the writhing process (p < 0.05). These results suggest that the Copaifera duckei oleoresin has topical antiinflammatory and analgesic activities.

We report a case of a lip granulomatous reaction after injection of silicone being treated successfully with topical Aldara (Imiquimod 5%). Silicone granulomas and the inflammatory foreign body reaction that can occur are some of the complications that arise from using silicone for cosmetic enhancement. The inflammatory reaction of this patient first appeared shortly after silicone injection of both the upper and lower lips. Histopathologic examination revealed a foreign body inflammatory reaction that is consistent with silicone granuloma. Although this reaction has been described extensively in the dermatologic literature as one of the disfiguring side effects of silicone injection, its treatment has plagued cosmetic dermatologists. We report the use of an immunomodulatory cream Aldara (Imiquimod 5%) to treat this type of reaction.

Column chromatographic fractionation of essential oil obtained by hydrodistillation from the flowering tops of S. ixiocephala resulted in the isolation of beta-caryophyllene, fenchyl acetate, T-cadinol and a new sesquiterpene alcohol for which a name ixiocephol has been proposed. The beta-caryophyllene and fenchyl acetate were identified by Co-TLC with authentic samples whereas T-cadinol and ixiocephol were structurally elucidated by UV, IR, 1H NMR, 13C NMR and Mass spectral data. The GC-MS analysis of the essential oil has also revealed the presence of various monoterpenoids and sesquiterpenoids. The essential oil of S. ixiocephala demonstrated a dose dependant anti-inflammatory activity in carrageenan-induced rat paw oedema. It has also revealed good activity in cotton pellet granuloma and adjuvant induced arthritis model in rats.
