Abstract
In this paper, we present the design and synthesis of a novel series of pyrido[2,3-d]pyridazine-2,8-dione derivatives via the annulation of the 2-pyridone pattern. The synthesized derivatives were evaluated for in vivo anti-inflammatory activity using an ear edema model. Compound 7c, which showed a greater inhibition of ear edema (82%), was further tested for its in vitro COX-1/COX-2 inhibitory activity. Compound 7c showed similar inhibitory activities against COX-1 and COX-2 isoenzymes. The structural features that ensure the dual inhibition of COX-1 and COX-2 were elucidated using molecular docking studies. Overall, the ring closing of 2-pyridone pattern I transformed this highly selective COX-2 inhibitor into a dual COX inhibitor (7c), which could serve as a model for determining selectivity for COX-2.

Abstract
AIMS To investigate the effects of resveratrol on glycogen catabolism and gluconeogenesis in perfused livers of healthy and arthritic rats. The actions of resveratrol-3-O-glucuronide (R3G) and the biotransformation of resveratrol into R3G was further evaluated in the livers. MAIN METHODS arthritis was induced with Freund's adjuvant. Resveratrol at concentrations of 10, 25, 50, 100 and 200 μM and 200 μM R3G were introduced in perfused livers. Resveratrol and metabolites were measured in the outflowing perfusate. Respiration of isolated mitochondria and activity of gluconeogenic enzymes were also evaluated in the livers. KEY FINDINGS resveratrol inhibited glycogen catabolism when infused at concentrations above 50 μM and gluconeogenesis even at 10 μM in both healthy and arthritic rat livers, but more sensitive in these latter. Resveratrol above 100 μM inhibited ADP-stimulated respiration and the activities of NADH- and succinate-oxidases in mitochondria, which were partially responsible for gluconeogenesis inhibition. Pyruvate carboxylase activity was inhibited by 25 μM resveratrol and should inhibit gluconeogenesis already at low concentrations. Resveratrol was significantly metabolized to R3G in healthy rat livers, however, R3G formation was lower in arthritic rat livers. The latter must be in part a consequence of a lower glucose disposal for glucuronidation. When compared to resveratrol, R3G inhibited gluconeogenesis in a lower extension and glycogen catabolism in a higher extension. SIGNIFICANCE the effects of resveratrol and R3G tended to be transitory and existed only when the resveratrol is present in the organ, however, they should be considered because significant serum concentrations of both are found after oral ingestion of resveratrol.

Abstract
Background and aim The present study investigated the effects of orally administered α-tocopherol-loaded polycaprolactone nanoparticles on the articular inflammation and systemic oxidative status of middle-aged Holtzman rats with Freund's adjuvant-induced polyarthritis, a model for rheumatoid arthritis. Intraperitoneally administered free α-tocopherol provided the reference for comparison. Experimental procedure Two protocols of treatment were followed: intraperitoneal administration of free α-tocopherol (100 mg/kg i.p.) or oral administration of free and nanoencapsulated α-tocopherol (100 mg/kg p.o.). Animals were treated during 18 days after arthritis induction. Results Free (i.p.) and encapsulated α-tocopherol decreased the hind paws edema, the leukocytes infiltration into femorotibial joints and the mRNA expression of pro-inflammatory cytokines in the tibial anterior muscle of arthritic rats, but the encapsulated compound was more effective. Free (i.p.) and encapsulated α-tocopherol decreased the high levels of reactive oxygen species in the brain and liver, but only the encapsulated compound decreased the levels of protein carbonyl groups in these organs. Both free (i.p.) and encapsulated α-tocopherol increased the α-tocopherol levels and the ratio of reduced to oxidized glutathione in these organs. Conclusion Both intraperitoneally administered free α-tocopherol and orally administered encapsulated α-tocopherol effectively improved inflammation and systemic oxidative stress in middle-aged arthritic rats. However, the encapsulated form should be preferred because the oral administration route does not be linked to the evident discomfort that is caused in general by injectable medicaments. Consequently, α-tocopherol-loaded polycaprolactone nanoparticles may be a promising adjuvant to the most current approaches aiming at rheumatoid arthritis therapy. Oxidative stress is systemically increased in rats with adjuvant-induced arthritis. Arthritic rats were orally treated with α-tocopherol-loaded polycaprolactone nanoparticles. Treatment decreased the paw edema and articular inflammation of arthritic rats. Treatment improved the oxidative stress in the liver and brain arthritic rats. The content of α-tocopherol was increased in the brain and liver of treated rats.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Miconia albicans (Sw.) Triana has been widely used in Brazilian popular medicine for the treatment of several diseases. Aerial parts are used as an infusion to treat arthrosis and arthritis, to relieve rheumatic and stomach pains, and intestinal disorders due to its anti-inflammatory, anti-mutagenic anti-nociceptive, digestive and hepatoprotective properties. AIM OF THE STUDY This study aimed to characterize the of M. albicans (Sw.) Triana fruits extract (MAFRE) chemical profile and to evaluate its antioxidant, anti-inflammatory and antitumor activities, as well as its toxicity. MATERIALS AND METHODS Maceration with methanol as liquid extractor was used to prepare MAFRE. M. albicans (Sw.) Triana fruits chemical composition was characterized by UHPLC-QTOF-MS/MS and GC-FID (fatty acid methyl esters composition from lyophilized fruits). MAFRE antioxidant potential was evaluated in vitro using a combination of assays: Folin-Ciocalteu reducing capacity, DPPH• and ABTS radical scavenging ability and ferric reducing antioxidant power (FRAP). In vitro antiproliferative activity was investigated in four human tumor cell lines (U251, 786-0, HT29 and MDA-MB-231) while the effect on the non-tumor cell viability was assessed in the VERO cell line using the on-step MTT assay. In addition, in vivo anti-inflammatory effect was assessed by Croton oil-induced ear edema in mice followed by myeloperoxidase (MPO) activity evaluation. RESULTS Thirty-five compounds were identified by UHPLC-QTOF-MS/MS. Among it flavonoids derived from quercetin (8), myricetin (1), kaempferol (2), terpenoids (6) and other compounds (18). GC-FID analysis identified and quantified nine fatty acids: palmitic, stearic, arachidic, behenic, elaidic, oleic, eicosenoic, and linoleic acids. The most abundant fatty acids were polyunsaturated fatty acids (5.33 ± 0.17 mg g-1), followed by saturated fatty acids (2.38 ± 0.07 mg g-1) and monounsaturated fatty acids (1.74 ± 0.09 mg g-1). The extract revealed high content of phenolic compounds (43.68 ± 0.50 mg GAE/g of extract), potent antioxidant, and ferrous chelating capacities. Morever, it proved to be non-toxic to the VERO cells, not affecting cells viability (95% of viable cells). No antiproliferative effect against human tumor cell lines were found. Furthermore, MAFRE significantly (p<0.05) reduced ear edema (≈35%) and MPO activity (84.5%) having a statistical effect similar to traditional steroidal and non-steroidal anti-inflammatory drugs. CONCLUSIONS Taken together, the results evidenced that M. albicans fruit extract has antioxidant properties, a higher concentration of phenolic compounds, flavonoids, fatty acids, and also topical anti-inflammatory activity with low toxicity of extract on VERO cells. Through the ethnomedicinal study, these findings supporting the popular use of M. albicans, but also highlight that not only aerial parts and leaves deserve attention, but the fruits also have anti-inflammatory proprieties and can be a source of phenolic compounds and other substances with potential health benefices.

Abstract
The present study evaluated the anti-inflammatory effect of nanoencapsulated curcuminoid preparations of poly(vinyl pyrrolidone) (Nano-cur) and free curcuminoids (Cur) in an experimental model of croton oil-induced cutaneous inflammation. Male Swiss mice, weighing 25-30 g, received oral treatment by gavage 1 h before CO application or topical treatment immediately after CO application (200 μg diluted in 70% acetone) with a single dose of Cur and Nano-cur. After 6 h, the animals were anesthetized and euthanized. The ears were sectioned into disks (6.0 mm diameter) and used to determine edema, myeloperoxidase (MPO) activity, and oxidative stress. Photoacoustic spectroscopy (PAS) was used to evaluate the percutaneous penetration of Cur and Nano-cur. Topical treatment with both preparations had a similar inhibitory effect on the development of edema, MPO activity, and the oxidative response. The PAS technique showed that the percutaneous permeation of both topically applied preparations was similar. Oral Nano-cur administration exerted a higher anti-inflammatory effect than Cur. Topical Cur and Nano-cur application at the same dose similarly inhibited the inflammatory and oxidative responses. Oral Nano-cur administration inhibited such responses at doses that were eight times lower than Cur, suggesting the better bioavailability of Nano-cur compared with Cur.Graphical abstract.

Abstract
The inflammatory response is the reaction of living tissue to an injury of a foreign nature, such as infection and irritants, and occurs as part of the body's natural defence response. Compounds capable of inhibiting cyclooxygenase (COX) enzymes, especially COX-2, have great potential as anti-inflammatory agents. Herein we present the regioselective synthesis of 49 novel compounds based on the 2-pyridone nucleus. The topical anti-inflammatory activity of seventeen compounds was evaluated in mice by croton oil (CO) induced ear edema assay. Most of the compounds exhibited a high level of in vivo anti-inflammatory activity, reducing ear edema and myeloperoxidase (MPO) activity. The most active compounds (2a and 7a) were inhibitors of COX enzymes. Compound 2a selectively inhibited the COX-2, while 7a was nonselective. Further, the compound 2a showed effective binding at the active site of COX-2 co-crystal by docking molecular study.

Abstract
Severe rheumatoid cachexia is associated with pronounced loss of muscle and fat mass in patients with advanced rheumatoid arthritis. This condition is associated with dyslipidemia and predisposition to cardiovascular diseases. Circulating levels of triglycerides (TG) and free fatty acids (FFA) have not yet been consistently defined in severe arthritis. Similarly, the metabolism of these lipids in the arthritic liver has not yet been clarified. Aiming at filling these gaps this study presents a characterization of the circulating lipid profile and of the fatty acids uptake and metabolism in perfused livers of rats with adjuvant-induced arthritis. The levels of TG and total cholesterol were reduced in both serum (10-20%) and liver (20-35%) of arthritic rats. The levels of circulating FFA were 40% higher in arthritic rats, possibly in consequence of cytokine-induced adipose tissue lipolysis. Hepatic uptake and oxidation of palmitic and oleic acids was higher in arthritic livers. The phenomenon results possibly from a more oxidized state of the arthritic liver. Indeed, NADPH/NADP+ and NADH/NAD+ ratios were 30% lower in arthritic livers, which additionally presented higher activities of the citric acid cycle driven by both endogenous and exogenous FFA. The lower levels of circulating and hepatic TG possibly are caused by an increased oxidation associated to a reduced synthesis of fatty acids in arthritic livers. These results reveal that the lipid hepatic metabolism in arthritic rats presents a strong catabolic tendency, a condition that should contribute to the marked cachexia described for arthritic rats and possibly for the severe rheumatoid arthritis.

Abstract
The crude extract and fractions from the branches of Ixora brevifolia, a tree found in the Brazilian Cerrado, were tested for anti-inflammatory and in vitro antiproliferative effects. The crude extract and n-hexane fraction exhibited significant inhibition of ear oedema in mice, while n-hexane-precipitated and chloroform fractions strongly inhibited the myeloperoxidase activity in ear tissue. The n-hexane and n-hexane-precipitated fractions showed strong growth inhibition for glioma cell line and the hydromethanolic fraction inhibited the growth of leukaemia cell line.

Abstract
This paper investigates the topical anti-inflammatory effect of a fish oil preparation (FOP) in a croton oil (CO) model of skin inflammation. The photoacoustic spectroscopy (PAS) was applied to estimate the percutaneous penetration of the FOP and as a model to evaluate the topical inflammatory response. After applying CO, the groups of mice received a topical application of a FOP on the left ear. The right ear received the vehicle that was used to dilute the CO. After 6 h, ear tissue was collected to determine the percent inhibition of edema, myeloperoxidase (MPO) activity, and cytokine levels and to perform PAS measurements. Treatment with FOP reduced edema and MPO activity, which was at least partially attributed to a decrease in the levels of tumor necrosis factor, interleukin- 1 ? , interleukin-6, keratinocyte-derived chemokine, and monocyte chemoattractant protein-1. The topically applied FOP penetrated into the tissue and decreased the area of the bands that characterize inflamed tissue. The present results demonstrated the topical anti-inflammatory effect of the FOP. PAS suggests that FOP anti-inflammatory activity is linked with its ability to penetrate through the skin.

Abstract
We aimed to evaluate the effects of aerobic exercise training (4 days) and metformin
exposure on acute glucose intolerance after dexamethasone treatment in rats.
Forty-two adult male Wistar rats (8 weeks old) were divided randomly into four
groups: sedentary control (SCT), sedentary dexamethasone-treated (SDX), training
dexamethasone-treated (DPE), and dexamethasone and metformin treated group (DMT).
Glucose tolerance tests and in situ liver perfusion were undertaken
on fasting rats to obtain glucose profiles. The DPE group displayed a significant
decrease in glucose values compared with the SDX group. Average glucose levels in the
DPE group did not differ from those of the DMT group, so we suggest that exercise
training corrects dexamethasone-induced glucose intolerance and improves glucose
profiles in a similar manner to that observed with metformin. These data suggest that
exercise may prevent the development of glucose intolerance induced by dexamethasone
in rats to a similar magnitude to that observed after metformin treatment.

Abstract
Background: Eschweilera nana Miers is a tree widely distributed in Cerrado, Brazil. Objective: In this study, we aimed to describe its phytochemical properties and antioxidant and topical anti-inflammatory effects for the first time, as well validate an high performance liquid chromatography with ultraviolet/visible (HPLC-UV-Vis) method for the separation and quantification of the main components (hyperoside and rutin) in the hydroalcoholic extract of E. nana leaves. Materials and Methods: Structural identification of compounds in E. nana extract was performed by analysis of spectral data by 1H nuclear magnetic resonance, 13C nuclear magnetic resonance and/or ESI/EM. The HPLC-UV-Vis method was validated according International Conference on Harmonization (ICH) parameters. The 2,2’-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) and 1,1-diphenyl-2-picrylhydrazyl (DPPH) method were used for determination of in vitro antioxidant activities and the croton oil-induced inflammation for evaluation of in vivo anti-inflammatory effects. Results: Hyperoside, rutin, α-amirin, β-amirin, β-sitosterol, and stigmasterol were identified in the hydroalcoholic extract of E. nana leaves. HPLC-UV-Vis was validated according to ICH parameters. Furthermore, in vitro and in vivo assays demonstrated that the hydroalcoholic extract and methanol fraction showed significant antioxidant and topical anti-inflammatory effects, as they were able to reduce ear edema induced by croton-oil application. Conclusions: This research showed the first phytochemical study of E. nana extract and their biological activities may be associated with the presence of flavonoids in the extracts.

Abstract
In the current study we reported cultivation, extraction procedure, analysis and preliminary characterization of the aqueous extract from Cereus peruvianus callus culture and evaluated its anti ulcerogenic activity in vivo models of experimental ulcers in Wistar rats. The obtained aqueous extract from callus (AC) was dialyzed and subjected to freeze-thaw process, providing a possible polysaccharide. The carbohydrate and protein contents of the aqueous extract were estimated at 53.4% and 0.66%, respectively, composed primarily of galactose, arabinose and galacturonic acid, with minor amounts of glucose. This appeared heterogeneous when analyzed by high-performance size-exclusion chromatography and a multi-angle laser light scattering detector (HPSEC-MALLS). The AC was found to be significantly effective against ethanol-induced lesions but was ineffective against indomethacin-induced lesions. The callus culture of C. peruvianus is an alternative source for the synthesis of substances originally produced by plants. The calluses grown indefinitely in vitro under controlled conditions are stable tissues, and the aqueous extract from calluses may be used instead of fully developed plants using the protocols described in this study.

Abstract
Anethole has been reported to have antioxidant, antibacterial, antifungal, antiinflammatory, and anesthetic properties. In the present study, we evaluated the effects of anethole in two pain models of inflammatory origin: acute inflammation induced by carrageenan and persistent inflammation induced by Complete Freund's adjuvant. We evaluated the effects of anethole (125, 250, and 500 mg/kg) on the development of paw oedema and mechanical hypernociception. The liver was collected for histological analysis. Paw skin was collected to determine the levels of the cytokines tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), interleukin-17 (IL-17), and myeloperoxidase activity. Blood was collected to assess alanine transaminase (ALT) and aspartate transaminase (AST). The chemical composition of star anise oil was determined by gas chromatography/mass spectrometry (GC/MS), showing a presence of anethole of 98.1%. Oral pretreatment with anethole in mice inhibited paw oedema, mechanical pernociception, myelopewroxidase activity, TNF-α, IL-1β and IL-17 levels in acute and persistent inflammation models. Additionally, anethole treatment did not alter prostaglandin E2-induced mechanical hypernociception. Possible side effects were also examined. Seven-day anethole treatment did not alter plasma AST and ALT levels, and the histological profile of liver tissue was normal. The present study provides evidence of the antiinflammatory and analgesic activities of anethole in acute and persistent inflammation models.

Abstract
Rosmarinus officinalis L. (Lamiaceae), popularly known as rosemary, is used for food flavoring and in folk medicine as an antispasmodic, analgesic, antirheumatic, diuretic, and antiepileptic agent. Few studies have shown the anti-inflammatory effects of rosemary essential oil (REO). This study evaluated the effects of REO on leukocyte migration through in vivo leukocyte migration and in vitro chemotaxis assay. REO was analyzed by using gas chromatography-mass spectometry, and the main components identified were camphor (27.59%), 1,8-cineole (15.74%), α-pinene (16.58%), and β-myrcene (10.02%). In rats, administration of REO reduced the number of leukocytes that rolled, adhered, and migrated to the scrotal chamber after carrageenan injection. All doses of REO tested significantly inhibited leukocyte chemotaxis induced by casein. The effects of REO on leukocyte migration highlight an important mechanism of the anti-inflammatory action of rosemary.

Abstract
Zingiber officinale Roscoe, popular name ginger, is grown naturally in many parts of the world, including Brazil. Ginger is used in pharmaceutical, cosmetic, and food and beverage industries and the essential oil has been used in folk medicine for manifold conditions including as an analgesic, anti-inflammatory, and antirheumatic. The purpose of this study was to investigate the effects of ginger (Zingiber officinale Roscoe) essential oil (GEO) in an in vitro chemotaxis assay and on leukocyte-endothelial interactions in vivo. GEO was analyzed by GC-MS and the main components identified were ar-curcumene (59%), β-myrcene (14%), 1,8-cineol (8%), citral (7.5%), and zingiberene (7.5%). Oral administration of GEO (200-500 mg/kg) reduced the rolling and leukocyte adherence after 2 h of carrageenan injection (100 μg) into the scrotal chamber. The number of leukocytes migrated to the perivascular tissue 4 h after the irritant stimulus was also diminished. GEO in all doses tested (10(-4), 10(-3), or 10(-2) μL/mL) caused a significant reduction of leukocyte chemotaxis (35.89 ± 4.33, 30.67 ± 0.70, and 35.85 ± 3.83%, respectively) toward casein stimuli. The data presented showed direct and systemic effects of GEO on leukocyte migration as an important mechanism of the anti-inflammatory action of ginger.

Abstract
The present study investigated arthritis induced by complete Freund adjuvant (AIA) in spontaneously hypertensive and normotensive rats (respectively, SHR and NTR rats). The inflammatory reaction was studied for 28 days by evaluating paw edema and secondary lesions found 10 days after complete Freund adjuvant (CFA) administration. The body weight of the animals and macroscopic alterations of several organs, including spleen, thymus, adrenal glands, and lymph nodes, were also analyzed. The results showed that the AIA manifestations were decreased in SHRs compared with NTRs. Moreover, this altered inflammatory response was not modified by surgical adrenalectomy.

Abstract
Rosmarinus officinalis L. (Family Lamiaceae), popularly named rosemary, is a common household plant grown in many parts of the world, including Brazil. Rosemary leaves are used for food flavoring and have been used in folk medicine for many conditions; they have antispasmodic, analgesic, antirheumatic, carminative, cholagogue, diuretic, expectorant, and antiepileptic effects. The objective of this study was to evaluate the effects of rosemary essential oil (REO) on experimental models of nociception and inflammation in animals. The anti-inflammatory effect of REO was evaluated by inflammatory exudate volume and leukocyte migration in carrageenan-induced pleurisy and carrageenan-induced paw edema tests in rats. Antinociception was evaluated using the acetic acid-induced writhing and hot plate tests in mice. REO (500 mg/kg) significantly reduced the volume of pleural exudate and slightly decreased the number of cells that had migrated compared with the control animals. At doses of 250, 500, and 750 mg/kg, REO significantly inhibited carrageenan-induced edema 1-4 hours after injection of the phlogistic agent. In the hot plate test, REO administration (125, 250, and 500 mg/kg) showed unremarkable effects on response latency, whereas control injection of meperidine induced significant antinociceptive effects. REO at doses of 70, 125, and 250 mg/kg had a significant antinociceptive effect in the acetic acid-induced abdominal writhing test compared with control animals. These data suggest that REO possesses anti-inflammatory and peripheral antinociceptive activity.

Abstract
Leaves of Piper ovatum are known in folk medicine as "joão burandi" or "anestésica" and in traditional Brazilian medicine are used to treat inflammatory disease. The hydroalcoholic extract, fractions, and a mixture of piperovatine (1) and piperlonguminine (2) in a proportion of 2:3 obtained from Piper ovatum were assayed for anti-inflammatory activity by means of carrageenan-induced pleurisy in rats and croton oil-induced ear edema in mice. The hydroalcoholic extract was analyzed by high-performance liquid chromatography. Fraction constituents were evaluated by phytochemical screening, and the mixture of amides (1 and 2) was identified by analyses of spectral data of (1)H and (13)C nuclear magnetic resonance. Acute toxicity of the extract also was evaluated. At 500mg/kg, the hydroalcoholic extract of Piper ovatum leaves did not reduce the volume of inflammatory pleural exudates compared with control animals. However, the hydroalcoholic extract and fractions F1-F3 at doses of 5.0mg/ear and a mixture of piperovatine (1) and piperlonguminine (2) at doses of 2.5, 1.25, and 0.625mg/ear significantly reduced the degree of ear edema. Taken together, the results indicate that the amide fractions piperovatine and piperlonguminine showed the greatest inhibitory activity of topical inflammation induced by croton oil.

Abstract
UNLABELLED The present study investigated the acute inflammatory response (increase in vascular permeability and leukocytes migration) in the pleura of spontaneously hypertensive rats (SHR) and normotensive rats (NTR), using two different stimulus: carrageenan and active anaphylaxis. In addition, the role of endogenous nitric oxide in these responses was investigated. RESULTS The inflammatory response induced by intrapleural carrageenan injection in SHR developed similarly to that in NTR. Treatment with L-NAME, reduced the intensity of this response in both groups of rats. The inflammatory response induced by active anaphylaxis in SHR and NTR was different. The increase in vascular permeability occurred later in the SHR compared to NTR. The number of leukocyte present in inflammatory exudates was increased at 4 h in both groups of rats. L-NAME treatment did not inhibit exudation at the intervals under analysis, however, reduced the number of mononuclear cells in the inflammatory exudate of SHR. CONCLUSION The development of the inflammatory response in SHR differs from that in NTR, depending on the nature of the inflammatory stimulus. Endogenous NO plays a clear role in carrageenan-induced inflamma-tion, but not in immunologically mediated inflammation in the analyzed period.

Abstract
The reaction of subcutaneous tissues to Endofill, Endomethasone, Sealer 26, and AH-Plus was investigated microscopically after implantation of in rats polyethylene cannulae, obturated with gutta-percha cones and sealers, in rats. Empty polyethylene cannulae and cannulae filled with gutta-percha cones alone were used as controls. The inflammatory reactions caused by the sealers were evaluated 7, 14, and 30 days after implantation using a descriptive, histopathological analysis. Inflammatory reactions at each implant site were gauged as either absent, discreet, moderate, or intense, and scores from 0 to 3 were attributed, respectively. Microscopic analysis revealed that Endomethasone showed the best biological behavior for all postimplant periods, followed by Sealer 26 and AH Plus, which produced an irritating effect only during the initial pos-implant period. Endofill caused the severest irritation, producing an inflammatory reaction that ranged from moderate to intense over the entire experimental period. Reactions were more intense near those parts of the cannulae containing more sealer. These results reveal that the root canal sealers tested cause inflammation in rat, subcutaneous conjunctive tissue, the intensity of which may be related to the type and quantity of sealer used, and to postimplant period.

Abstract
The action of orally administered dexamethasone (0.2 mg kg(-1) day(-1)) on metabolic parameters of adjuvant-induced arthritic rats was investigated. The body weight gain and the progression of the disease were also monitored. Dexamethasone was very effective in suppressing the Freund's adjuvant-induced paw edema and the appearance of secondary lesions. In contrast, the body weight loss of dexamethasone-treated arthritic rats was more accentuated than that of untreated arthritic or normal rats treated with dexamethasone, indicating additive harmful effects. The perfused livers from dexamethasone-treated arthritic rats presented high content of glycogen in both fed and fasted conditions, as indicated by the higher rates of glucose release in the absence of exogenous substrate. The metabolization of exogenous L: -alanine was increased in livers from dexamethasone-treated arthritic rats in comparison with untreated arthritic rats, but there was a diversion of carbon flux from glucose to L: -lactate and pyruvate. Plasmatic levels of insulin and glucose were significantly higher in arthritic rats following dexamethasone administration. Most of these changes were also found in livers from normal rats treated with dexamethasone. The observed changes in L: -alanine metabolism and glycogen synthesis indicate that insulin was the dominant hormone in the regulation of the liver glucose metabolism even in the fasting condition. The prevalence of the metabolic effects of dexamethasone over those ones induced by the arthritis disease suggests that dexamethasone administration was able to suppress the mechanisms implicated in the development of the arthritis-induced hepatic metabolic changes. It seems thus plausible to assume that those factors responsible for the inflammatory responses in the paws and for the secondary lesions may be also implicated in the liver metabolic changes, but not in the body weight loss of arthritic rats.

Abstract
This study was carried out to evaluate whether the anti-inflammatory response in rats to the whole extract of Harpagophytum procumbens is a consequence of adrenal corticosteroid release. Carrageenan-induced inflammatory responses in the hindpaws were evaluated in control, sham-operated and adrenalectomized rats. The extract was administered orally (by gavage) or intraperitoneally, 30min prior to injury stimulus. Blood samples were then collected, and the number of circulating leukocytes was estimated. Pretreatment with the whole extract of H. procumbens reduced the intensity of inflammatory response in normal, sham-operated and adrenalectomized animals. When administered orally, the extract was ineffective. The reduced number of circulating leukocytes observed following intraperitoneal injection of the extract characterized adrenal hyperactivity. The inhibitory effect of the whole extract of H. procumbens on acute inflammatory response in the rat, when administered intraperitoneally, does not depend on the release of adrenal corticosteroids.

Abstract
The present study evaluates the effects of methotrexate (MTX) and chloroquine (CQ), and of combined MTX + CQ treatment, on the inflammatory response and on plasma and liver phosphatase and transaminase activities, employing an adjuvant-induced arthritis model in rats. Arthritis was induced by the intradermal injection of a suspension of Mycobacterium tuberculosis in mineral oil into the plantar surface of the hind paws. Development of the inflammatory response was assessed over a 21-day period. Animal groups received either: (i) MTX, administered i.p., weekly, in 0.15, 1.5, 3, 6 or 12 mg/kg doses; (ii) CQ, given intragastrically, in daily 25 or 50 mg/kg doses; or (iii) MTX + CQ, administered in two combinations (MTX1.5 mg/kg + CQ50 mg/kg, or MTX6 mg/kg + CQ50 mg/kg). At the end of the experimental period, the animals were anesthetized and killed, blood and liver samples were collected and prepared for measurement of acid and alkaline phosphatase (AP, ALP), and aspartate (AST) and alanine aminotransferase (ALT) activities. MTX at 6 and 12 mg/kg reduced the inflammatory response while CQ had no effect. MTX6 mg/kg + CQ50 mg/kg reduced the inflammatory response similar to MTX12 mg/kg, without affecting the bone marrow. Plasma AP and liver ALP activities were very elevated in the arthritic rats. While MTX treatment partially reduced both plasma AP and liver ALP activities at all doses used in the arthritic rats, CQ treatment reduced plasma AP, but increased liver AP activity. MTX + CQ treatment decreased plasma AP and liver ALP activities in the arthritic rats to control values. Plasma and liver AST activities were unaltered in the arthritic rats, and were unaffected by treatment. However, plasma and liver ALT activities were significantly reduced in the arthritic rats. While MTX or CQ treatment did not alter plasma transaminase activity in the arthritic rats, after MTX + CQ treatment, plasma ALT activity returned to normal values. In conclusion, the present data suggest that MTX + CQ treatment provides more effective anti-inflammatory protection against adjuvant-induced arthritis than does MTX alone, reverting the alterations in enzyme activities induced by this inflammatory disease in rats.

Abstract
This study investigates the action of Canova medication (CM) on experimental infection by Leishmania (Leishmania) amazonensis, utilizing in vitro and in vivo assays. For the in vitro tests, Balb/c mouse peritoneal macrophages (5x10(5) cells in 500 microl of culture medium, supplemented with 10% fetal calf serum, penicillin (100 U/ml) and streptomycin (0.1 mg/ml) (were distributed in 24-well plates and CM was added at concentrations of 20 or 40%. Twenty-four hours later, the macrophages were infected with Leishmania amastigotes in culture medium. The effect of CM on macrophages leishmanicidal activity in 24 and 48 h cultures was evaluated by determining infection index and measuring nitric oxide (NO) production. The in vivo tests were performed in mice infected with 10(7)L. (L.) amazonensis promastigotes injected in to the right hind footpad (25 microl in phosphate buffered saline). The progression of the lesions was examined over a 9-week period by measuring footpad swelling, and the parasite load in regional lymph nodes and spleen. The in vitro results showed that at 40% CM reduced the infection index, and induced NO production in the elicited macrophages, which suggests that the inhibitory effect on infection index may be mediated by NO. In the in vivo infection, when administered, orally or subcutaneously in mice, CM reduced infection by L. (L.) amazonensis in the paws, resulting in smaller lesions. CM treatment also decreased parasite load in the regional popliteal lymph nodes and in the spleen. These results suggest that CM modulates experimental infection by L. (L.) amazonensis, controlling infection progression and limiting dissemination.

Abstract
The inflammatory response is decreased in diabetic animals. After adrenals removal this impaired response in type 2 diabetic rats evaluated by pleurisy and vascular permeability tests was restored. Our studies demonstrate that endogenous corticosteroids play a partial role in the impaired inflammatory response in type 2 streptozotocin diabetic rats.

Abstract
OBJECTIVES AND DESIGN To verify whether the inflammatory responses in animals with type 2 diabetes are altered to an extent similar to that in type 1 diabetes. MATERIALS Male newborn (2 days old) Wistar rats were made diabetic by streptozotocin (160 mg/kg, i.p.) and used 8-10 weeks later (10 rats/group). METHODS The inflammatory responses were evaluated using paw edema (induced by local injection of carrageenan or dextran), pleurisy (by pleural injection of carrageenan), increases in vascular permeability (induced by intradermal injection of histamine, serotonin and bradykinin) and leukocyte counts in peripheral blood and pleural exudate. RESULTS Diabetic animals showed reduced inflammatory responses to carrageenan but not to dextran. The increase in vascular permeability induced by serotonin and bradykinin was reduced whereas that to histamine was not altered in diabetic compared to control rats. Although the pleural exudate was reduced, leukocyte counts were similar in diabetic and control rats. Insulin (2 IU, 4 h before), though effective in reducing blood sugar levels, did not restore the altered responses in diabetic rats. In contrast to that in rats with type 1 diabetes, in rats with type 2 diabetes, removal of the adrenal glands restored the reduced inflammatory responses. CONCLUSIONS Insulin resistance in type 2 diabetic rats led to reduced inflammatory responses, which were partially corrected by adrenalectomy.

Abstract
The aim of the present study was to evaluate the changes caused by adjuvant-induced arthritis in liver mitochondria and to investigate the effects of the nonsteroidal anti-inflammatory drug nimesulide. The main alterations observed in liver mitochondria from arthritic rats were: higher rates of state IV and state III respiration with beta-hydroxybutyrate as substrate; reduced respiratory control ratio and impaired capacity for swelling dependent on beta-hydroxybutyrate oxidation. No alterations were found in the activities of NADH oxidase and ATPase. Nimesulide produced: (1) stimulation of state IV respiration; (2) decrease in the ADP/O ratio and in the respiratory control ratio; (3) stimulation of ATPase activity of intact mitochondria; (4) inhibition of swelling driven by the oxidation of beta-hydroxybutyrate; (5) induction of passive swelling due to NH(3)/NH(4)+ redistribution. The activity of NADH oxidase was insensitive to nimesulide. Mitochondria from arthritic rats showed higher sensitivity to nimesulide regarding respiratory activity. The results of this work allow us to conclude that adjuvant-induced arthritis leads to quantitative changes in some mitochondrial functions and in the sensitivity to nimesulide. Direct evidence that nimesulide acts as an uncoupler was also presented. Since nimesulide was active in liver mitochondria at therapeutic levels, the impairment of energy metabolism could lead to disturbances in the liver responses to inflammation, a fact that should be considered in therapeutic intervention.

Abstract
The antiulcer activity of Maytenus aquifolium spray dried extract was studied in rats. Ulcers were induced by means of three experimental models: acidified-ethanol, indomethacin and acute stress. The extract was found to have significant antiulcer activity against all the models studied. These results show that preparation of the extract by means of the spray dried technique does not alter the biological activity of Maytenus aquifolium.

Abstract
The antiulcer activity of the total extract and the fractions of Stryphnodendron adstringens was studied in rats and compared with that of cimetidine. Ulcers were induced in rats by means of three experimental models: acute stress, acidified-ethanol and indomethacin. The total extract and the fractions were found to have significant antiulcer activity in the case of the acute stress and acidified-ethanol models. These findings support the use of S. adstringens extracts in the treatment of gastric lesions.

Abstract
AIM To evaluate the irritative potential of three dental bleaching agents (hydrogen oxide, carbopol, and carbamide peroxide). METHODS In rats, Evans blue (2.5%, 1 mL.L-1) was injected i.v. and later each test solution was injected intradermally on the back. After the concentration of the dye in the stained skin area was determined by spectrophotometric analysis. RESULTS All the dental bleaching agents caused increase of vascular permeability and the intensity varied with the time. CONCLUSION Dental bleach agents had a great potential for irritating soft tissues.

Abstract
The effects of nimesulide on energy metabolism and the hepatic metabolic alterations produced by adjuvant-induced arthritis were investigated in the perfused rat liver an in isolated liver mitochondria. Nimesulide, at therapeutic levels (20-50 microM), produced: (1) stimulation of oxygen consumption in the perfused rat liver and in isolated mitochondria, (2) inhibition of gluconeogenesis; (3) reduction of ADP/O ratio and the respiratory control ratio and stimulation of glycogenolysis in the livers from healthy rats, but not in livers from arthritic rats. These results indicate that nimesulide acts as a mitochondrial uncoupler. The main alterations produced by adjuvant-induced arthritis were: higher rates of oxygen consumption in both perfused livers and isolated mitochondria, with no decrease in the efficiency of mitochondrial energy transduction; (2) decreased gluconeogenesis and lack of glycogenolytic response to uncouplers, but not to alpha 1-agonists. These data allow to conclude that nimesulide-induced impairment of energy metabolism should worsen the hepatic disturbances that are already associated with the adjuvant disease.

Abstract
1. The absorption of piroxicam into the blood of rats is significantly slower after oral administration of piroxicam beta-cyclodextrin than of free piroxicam. 2. The pharmacokinetic profiles of piroxicam in rat lymph were very similar in both groups. 3. Bioavailability of piroxicam in plasma is higher after treatment with the inclusion product than with free piroxicam. On the other hand, bioavailability in lymph is higher when free piroxicam is administered.

Abstract
In rats of the Holtzman strain, susceptible to the development of adjuvant induced arthritis (AIA), oral administration of BCG significantly inhibited the development of the disease. Oral treatment with purified protein derivative (PPD) had no effect. In the resistant Buffalo rats, however, oral administration of BCG and PPD enhanced the lesions. Since oral administration of antigens has been described to induce suppressor cells, our results suggest that the development of AIA is controlled by suppressor mechanisms, which fail to be activated in the susceptible strain, but are stimulated by the oral administration of BCG.

Abstract
The subpopulations of lymphocytes (W3/25+ and OX8+) in the blood, spleen and lymph nodes were analyzed comparatively in rats susceptible (Holtzman) and resistant (Buffalo) to the development of adjuvant induced arthritis (AIA). In naive rats, it was found that the ratio (T helper/T suppressor) was significantly higher in Holtzman compared to Buffalo rats suggesting that the susceptible rats possess less suppressor cells than the resistant. Following induction of AIA (7 and 14 days) the ratio T helper/T suppressor was not significantly different in either strain. When the resistant strain was treated with 25 mg/kg of cyclophosphamide, the T suppressor cells were significantly reduced and this was followed by a strong potentiation of the AIA. Our data suggest that susceptibility to AIA is related to alterations in the T suppressor cell subset.

Abstract
Injection of complete Freund's adjuvant into one paw of Holtzman rats induced an inflammatory response in the injected site (primary lesion) and from the 10th day on, severe polyarthritis developed (secondary lesions). In this susceptible strain, cyclophosphamide dose dependently reduced the intensity of the primary and secondary lesions. In contrast, in Buffalo rats, which are considered as resistant, cyclophosphamide in the dose of 25 mg/kg significantly potentiated the secondary lesions. Higher doses (200 and 300 mg/kg) also reduced the intensity of the lesions in this strain. Our data suggest that the development of adjuvant induced arthritis is controlled by a cyclophosphamide sensitive suppressor cell population.
