Abstract
This study aimed to investigate the antioxidant and anti-inflammatory properties of quercetin on the cellular components of the Enteric Nervous System in the ileum of rats with arthritis. Rats were distributed into five groups: control (C), arthritic (AIA), arthritic treated with ibuprofen (AI), arthritic treated with quercetin (AQ) and arthritic treated with both ibuprofen and quercetin (AIQ). The ileum was processed for immunohistochemical techniques for HuC/D, calcitonin gene-related peptide, and vasoactive intestinal polypeptide. Measurements in histological sections, chemiluminescence assays, and total antioxidant capacity were also performed. Rheumatoid arthritis resulted in a decrease in neuronal density, yet neuroplasticity mechanisms were evident through observed changes in varicosities size and neuronal area compared to the control group. Reduced paw edema and neuroprotective effects were predominantly noted in both plexuses, as evidenced by the increased density preservation of HuC/D-IR neurons in the AIQ group. The increase of lipoperoxidation levels and paw edema volume in the AQ group was observed compared to the arthritic, whereas the AIQ group mainly showed similar results to those observed in the control. The enteropathy associated with arthritis proved to be significant in the field of gastroenterology, and the combination of quercetin and ibuprofen demonstrated promising anti-inflammatory and neuroprotective effects.

Abstract
Purpose Rheumatoid arthritis (RA) is a type of autoimmune disease that results in chronic inflammation of the joint synovial tissue, leading to joint damage and significant disability. Despite ongoing research, the exact cause of RA remains unclear, and current treatments have limitations. This study explores the potential of utilizing interleukin-1 receptor antagonist (IL-1RA) and anti-inflammatory macrophages polarized in the vicinity of the supernatant from allogeneic mesenchymal stem cells (MSCs) as a novel therapeutic approach for RA. Methods An expression cassette containing the IL-1RA gene was constructed and expressed in E. coli BL21. The resulting protein was purified and stabilized for use in in vivo experiments. Bone marrow MSCs were isolated and used to produce anti-inflammatory M2 macrophages from the isolated peripheral blood monocytes. The macrophages were then used to treat mice with RA induced by collagen type II. Results The combination of IL-1RA and M2 macrophages improved clinical and histopathological symptoms of the disease, reduced levels of inflammatory factors, and modulated the immune system in the treated mouse groups. The results showed that this combinatory therapy had a synergistic effect for RA treatment. Conclusion The simultaneous use of IL-1RA and M2 cells could be a promising approach for the treatment of RA. This combinatory therapy has the potential to improve the disease and decrease the severity of inflammation in patients with RA.

Abstract
PURPOSE Bee Venom (BV) has been used to treat rheumatoid arthritis (RA) for many centuries. However, its clinical use is limited by pain and fear of bee stings/injection. Nanoemulsions (NEs) are nanocarriers that are able to help their content(s) penetrate through the skin. They also act as drug reservoirs on the skin to provide an efficient, sustained-release vehicle. METHODS In this paper, we present the development of a stable water-in-oil NE to help passing BV through the animal skin when used topically. RESULTS Particle size of NE was 12.7 to 29.8 nm for NEs containing 0 to 150 µg/ml BV. Also, its anti-inflammatory effects were evaluated in rat models of type II collagen-induced arthritis. Topical administration of NEs containing 18.75 or 9.37 μg/ml BV were able to significantly (p<0.05) reduce inflammation in the rat paws compared to the blank and control groups. CONCLUSION Our findings demonstrated the efficacy of NEs containing BV to reduce inflammation caused by RA animal model.

Abstract
Rheumatoid arthritis (RA) is the most common inflammatory rheumatic disease, affecting almost 1% of the world population. It is a long-lasting autoimmune disease, which mainly affects the joints causing inflammation and swelling of the synovial joint. RA has a significant impact on the ability to perform daily activities including simple work and household chores. Nonetheless, due to the long periods of pain and the continuous use of anti-inflammatory drugs, RA can debilitate the quality of life and increases mortality. Current therapeutic approaches to treat RA aim to achieve prolonged activity and early and persistent remission of the disease, with the gradual adoption of different drugs available. In this study, we developed a novel hydroxychloroquine and methotrexate co-loaded Pluronic® F-127 nanomicelle and evaluated its therapeutic effects against RA. Our results showed that drug-loaded nanomicelles were capable of modulating the inflammatory process of RA and reducing osteoclastogenesis, edema, and cell migration to the joint. Overall, compared to the free drugs, the drug-loaded nanomicelles showed a 2-fold higher therapeutic effect.

Local controlled release of corticosteroids extends surgically induced joint instability by inhibiting tissue healing. Br J Pharmacol 2019; 176:4050-4064.

Abstract
BACKGROUND AND PURPOSE Corticosteroids are intra-articularly injected to relieve pain in joints with osteoarthritis (OA) or acute tissue damage such as ligament or tendon tears, despite its unverified contraindication in unstable joints. Biomaterial-based sustained delivery may prolong reduction of inflammatory pain, while avoiding harmful peak drug concentrations. EXPERIMENTAL APPROACH The applicability of prolonged corticosteroid exposure was examined in a rat model of anterior cruciate ligament and medial meniscus transection (ACLT + pMMx) with ensuing degenerative changes. KEY RESULTS Intra-articular injection of a bolus of the corticosteroid triamcinolone acetonide (TAA) resulted in enhanced joint instability in 50% of the joints, but neither instability-induced OA cartilage degeneration, synovitis, nor the OA-related bone phenotype was affected. However, biomaterial microsphere-based extended TAA release enhanced instability in 94% of the animals and induced dystrophic calcification and exacerbation of cartilage degeneration. In healthy joints, injection with TAA releasing microspheres had no effect at all. In vitro, TAA inhibited cell migration out of joint tissue explants, suggesting inhibited tissue healing in vivo as mechanisms for enhanced instability and subsequent cartilage degeneration. CONCLUSIONS AND IMPLICATIONS We conclude that short-term TAA exposure has minor effects on surgically induced unstable joints, but its extended presence is detrimental by extending instability and associated joint degeneration through compromised healing. This supports a contraindication of prolonged corticosteroid exposure in tissue damage-associated joint instability, but not of brief exposure.

Abstract
Objective One of the major side effects of glucocorticoid (GC) treatment is lean tissue wasting, indicating a prominent role in systemic amino acid metabolism. In order to uncover a novel aspect of GCs and their intracellular-receptor, the glucocorticoid receptor (GR), on metabolic control, we conducted amino acid and acylcarnitine profiling in human and mouse models of GC/GR gain- and loss-of-function. Methods Blood serum and tissue metabolite levels were determined in Human Addison's disease (AD) patients as well as in mouse models of systemic and liver-specific GR loss-of-function (AAV-miR-GR) with or without dexamethasone (DEX) treatments. Body composition and neuromuscular and metabolic function tests were conducted in vivo and ex vivo, the latter using precision cut liver slices. Results A serum metabolite signature of impaired urea cycle function (i.e. higher [ARG]:[ORN + CIT]) was observed in human (CTRL: 0.45 ± 0.03, AD: 1.29 ± 0.04; p < 0.001) and mouse (AAV-miR-NC: 0.97 ± 0.13, AAV-miR-GR: 2.20 ± 0.19; p < 0.001) GC/GR loss-of-function, with similar patterns also observed in liver. Serum urea levels were consistently affected by GC/GR gain- (∼+32%) and loss (∼−30%) -of-function. Combined liver-specific GR loss-of-function with DEX treatment revealed a tissue-autonomous role for the GR to coordinate an upregulation of liver urea production rate in vivo and ex vivo, and prevent hyperammonaemia and associated neuromuscular dysfunction in vivo. Liver mRNA expression profiling and GR-cistrome mining identified Arginase I (ARG1) a urea cycle gene targeted by the liver GR. Conclusions The liver GR controls systemic and liver urea cycle function by transcriptional regulation of ARG1 expression. Metabolite profiling revealed a role for the HPA-axis-liver GR in regulating urea cycle function in mouse and humans. The liver GR controls enhanced urea cycle function during chronic glucocorticoid exposure. Liver Arginase I is a key urea cycle transcript regulated by the GR.

Abstract
Corticosteroids are used in musculoskeletal diseases, and offer patient relief. Injections of corticosteroids are recommended for management of osteoarthritis (OA). Current data have shown the role of corticosteroids in ameliorating pain. We hypothesized that repeated intra-articular injections of high dose dexamethasone would protect the cartilage from damage in a post-traumatic model of OA. Eighteen female New Zealand White rabbits were used. Twelve underwent surgery to induce OA; six of them received intra-articular injections of dexamethasone every 3 days for 3 weeks. The other six rabbits served as operated controls. Six additional rabbits served as non-operated controls. All animals were euthanized 3 weeks post-surgery. Knees were assessed grossly. Cartilage, synovium, and fat pad were assessed histologically. Synovium and fat pad were analyzed with qPCR and Western blots. Surgical controls had cartilage damage which was supressed with dexamethasone. Dexamethasone significantly decreased synovial expression of interleukin-1β and collagen I, and a trend to decrease synovial matrix metalloproteinase3 expression. There were also significantly lower levels of interleukin-1β protein with dexamethasone treatment. Dexamethasone significantly decreased fat pad expression of matrix metalloproteinase13, basic fibroblast growth factor, and interleukin8, and a trend to decrease matrix metalloproteinase3 and transforming growth factorβ expression. Dexamethasone decreased joint inflammation and joint tissue degradation and was chondroprotective in this unique model of PTOA.

Abstract
In the past decades, glucocorticoid (GC) hormones and their cognate, intracellular receptor, the glucocorticoid receptor (GR), have been well established as critical checkpoints in mammalian energy homeostasis. Whereas many aspects in healthy nutrient metabolism require physiological levels and/or action of GC, aberrant GC/GR signalling has been linked to severe metabolic dysfunction, including obesity, insulin resistance and type 2 diabetes. Consequently, studies of the molecular mechanisms within the GC signalling axis have become a major focus in biomedical research, up-to-date particularly focusing on systemic glucose and lipid handling. However, with the availability of novel high throughput technologies and more sophisticated metabolic phenotyping capabilities, as-yet non-appreciated, metabolic functions of GC have been recently discovered, including regulatory roles of the GC/GR axis in protein and bile acid homeostasis as well as metabolic inter-organ communication. Therefore, this review summarises recent advances in GC/GR biology, and summarises findings relevant for basic and translational metabolic research.

Abstract
We assessed the therapeutic effect of exogenous melatonin (MEL), dexamethasone (DEXA), and a combination of both on nociceptive response induced by chronic inflammation and on the rest-activity circadian rhythm in rats. A total of 64 animals were randomly divided into eight groups of eight rats each: one control group and seven groups with complete Freund's adjuvant-inflamed animals (CFA; injection into the footpad). One of the CFA-inflamed groups did not receive any treatment; the other six were treated with melatonin (MEL), dexamethasone (DEXA), melatonin plus dexamethasone (MELDEXA), and their respective vehicles. Fifteen days after CFA injection, animals were treated with intraperitoneal injection of MEL (50 mg/kg) or its vehicle (8% ethanol in saline), DEXA (0.25 mg/kg) or its vehicle (saline), and MEL plus DEXA or their vehicles, for 8 days. The von Frey test was performed 24 h after the last administration of each treatment regimen. Hind paw thickness was measured using a pachymeter during the treatment days. The degree of swelling and histological findings were analyzed. All treated groups significantly reduced the severity of inflammation when compared with their vehicles (repeated-measures analysis of variance [ANOVA], p < 0.05 for all analyses). Inflamed animals treated with dexamethasone alone or associated with melatonin showed marked inhibition of histological findings. On the other hand, the group treated with melatonin remained with moderate inflammation. The CFA group showed a decrease in the mean rest-activity circadian rhythm, determined by the number of touch-detections per hour during water intake in comparison with the control group; only the group treated with melatonin showed a synchronized rest-activity rhythm. At the end of treatment, a significant increase was observed in hind paw withdrawal threshold on the von Frey test in the treated groups (one-way ANOVA, p < 0.05 for all). Our findings showed that melatonin (50 mg/kg) has strong chronobiotic and antinociceptive effects, but only mild anti-inflammatory effects. This evidence supports the hypothesis that melatonin can induce phase advance and circadian rhythm synchronization in rats with chronic inflammation.

Abstract
Dexamethasone is widely used in the therapy of chronic inflammatory diseases for its pain-modulating effects. The objective of this study was to evaluate the effect of dexamethasone on nociception and local inflammation, and the levels of brain-derived neurotrophic factor (BDNF) in the spinal cord in male rats with chronic inflammation induced by complete Freund's adjuvant (CFA). Rats were randomly divided into a control group (not manipulated) and 2 CFA-induced chronic inflammation groups (in the 15th post-CFA injection): 1 injected with vehicle (saline solution) and 1 received dexamethasone (0.25 mg/kg) for 8 days. The hot-plate and electronic von Frey tests were performed 24 h after the end of treatment. BDNF spinal cord levels were determined by enzyme-linked immunosorbent assay (ELISA). The level of inflammation in the tibiotarsal joint (the ankle region) was evaluated histologically at the end of treatment. Dexamethasone produced significantly increased latency in the hot-plate test (one-way ANOVA, p < 0.05) and withdrawal threshold in the electronic von Frey test (p < 0.005). The dexamethasone group showed increased spinal cord BDNF levels compared to the other groups (one-way ANOVA p, < 0.05). Histological analysis showed a local inflammatory response only in animals treated with vehicle, which demonstrated that the dexamethasone treatment decreased the inflammatory process. Our findings corroborate the antinociceptive and anti-inflammatory properties of dexamethasone. In addition, we showed that the dexamethasone treatment increased BDNF levels in the spinal cord; its pain- modulating effects can be attributed to this effect.

Abstract
In the study, indomethacin, cyclophosphamide, and infliximab were administered to adjuvant-induced arthritic rats to determine if they were able to prevent the abnormalities caused by arthritis on hepatic metabolism. The drugs were administered to arthritic rats, and at the clinical onset of arthritis (day 14 after adjuvant injection), the livers were perfused to evaluate gluconeogenesis, ureagenesis, oxygen uptake, L: -lactate, pyruvate, and ammonia release from L: -alanine. The effects of the drugs on body weight gain and the signs of arthritis (paw edema, appearance of secondary lesions, and weights of lymphoid tissues) were also evaluated. Cyclophosphamide could completely prevent liver metabolic changes and the inflammatory response. Indomethacin restored ureagenesis, minimized the decrease in gluconeogenesis, and exerted a partially beneficial effect on inflammatory reactions. Infliximab did not improve arthritis-induced liver metabolic alterations or inflammatory responses. These results suggest the participation of prostaglandins, but not TNF-α, on arthritis-induced liver metabolic alterations.

Abstract
The hepatic response to cyclic adenosine monophosphate (cAMP) and N6-monobutyryl-cAMP (N6-MB-cAMP) in the glucose and glycogen catabolism and hepatic glycogen levels were evaluated in Walker-256 tumor-bearing rats, on days 5 (WK5), 8 (WK8), and 11 (WK11) after the implantation of tumor. Rats without tumor fed ad libitum (fed control rats) or that received the same daily amount of food ingested by anorexics tumor-bearing rats (pair-fed control rats) or 24 h fasted (fasted control rats) were used as controls. Glucose and glycogen catabolism were measured in perfused liver. Hepatic glycogen levels were lower (p < 0.05) in WK5, WK8, and WK11 rats in comparison with fed control rats, but not in relation to the pair-fed control rats. However, the stimulatory effect of cAMP (3 and 9 μM) in the glycogen catabolism was lower (p < 0.05), respectively, in WK5 and WK8 rats compared to the pair-fed and fed control rats. Accordingly, the suppressive effect of cAMP (6 μM) in the glucose catabolism, under condition of depletion of hepatic glycogen (24 h fast), was lower (p < 0.05) in WK5 and WK11 rats than in fasted control rats. Similarly, the suppressive effect of N6-MB-cAMP (1 μM), a synthetic analogue of cAMP that it is not degraded by phosphodiesterase 3B (PDE3B), in the glucose catabolism was lower (p < 0.05) in WK5 rats compared to fasted control rats. In conclusion, livers of Walker-256 tumor-bearing rats showed lower response to cAMP in the glucose and glycogen catabolism in various stages of tumor development (days 5, 8 and 11), which was probably not due to the lower hepatic glycogen levels nor due to the increased activity of PDE3B.

Abstract
OBJECTIVE To determine the contributions of angiogenesis to inflammation, joint damage, and pain behavior in a rat meniscal transection model of osteoarthritis (OA). METHODS OA was induced in male Lewis rats (n=8 per group) by meniscal transection. Animals were orally dosed with dexamethasone (0.1 mg/kg/day), indomethacin (2 mg/kg/day), or the specific angiogenesis inhibitor PPI-2458 (5 mg/kg every other day). Controls consisted of naive and vehicle-treated rats. Synovial inflammation was measured as the macrophage fractional area (expressed as the percentage), thickness of the synovial lining, and joint swelling. Synovial angiogenesis was measured using the endothelial cell proliferation index and vascular density. Channels positive for vessels at the osteochondral junction were assessed (osteochondral angiogenesis). Medial tibial plateaus were assessed for chondropathy, osteophytosis, and channels crossing the osteochondral junction. Pain behavior was measured as weight-bearing asymmetry. RESULTS Dexamethasone and indomethacin each reduced pain behavior, synovial inflammation, and synovial angiogenesis 35 days after meniscal transection. Dexamethasone reduced, but indomethacin had no significant effect on, the total joint damage score. PPI-2458 treatment reduced synovial and osteochondral angiogenesis, synovial inflammation, joint damage, and pain behavior. CONCLUSION Our findings indicate that synovial inflammation and joint damage are closely associated with pain behavior in the meniscal transection model of OA. Inhibition of angiogenesis may reduce pain behavior both by reducing synovitis and by preventing structural change. Targeting angiogenesis could therefore prove useful in reducing pain and structural damage in OA.

Abstract
AIM Although, pharmacological activation of heme oxygenase (HO)-1 has shown to produce ameliorative effects in various experimental models of inflammation, but such beneficial effects have not been observed in adjuvant-induced arthritis. Further, the upregulated activity of HO-1 has been implicated in the pathogenesis of adjuvant arthritis. The present study was designed to investigate the anti-inflammatory and antihyperalgesic effects of the prophylactic use of hemin alone and/or in combination with ibuprofen using adjuvant-induced arthritis in Wistar rat. METHODS Arthritis was induced by an intradermal injection of complete Freund's adjuvant (CFA) into left hind paw. Paw volume, thermal hyperalgesia, mechanical allodynia, joint stiffness and mobility behaviors (score) were measured. RESULTS Administration of ibuprofen (8.75, 17.5, 35 mg/kg/day, p.o.) and hemin (1, 5, 10 mg/kg/day, i.p.) were significantly effective in suppressing CFA-induced paw oedema, thermal and mechanical hyperalgesia, joint stiffness and mobility. The combination of low doses of ibuprofen (8.75 mg/kg, p.o.) and hemin (1 mg/kg, i.p.) significantly reduced paw volume, thermal and mechanical hyperalgesia, as compared to the individual dose of the ibuprofen and hemin alone. CONCLUSIONS Hence, it may be concluded that the prophylactic administration of either hemin produced significantly enhanced anti-inflammatory and analgesic effects. Further, concurrent low dose administration of hemin and ibuprofen produced significantly enhanced anti-inflammatory and analgesic effects, as compared to the either treatment alone, in CFA-induced arthritis in Wistar rats.

Abstract
In this study, simvastatin, atorvastatin, ezetimibe, and ezetimibe + simvastatin combination were administered to arthritic rats, first to determine their effects on the inflammatory response, employing a low-dose adjuvant-induced arthritis model in rats. Arthritis was induced by the subcutaneous injection of a suspension of Mycobacterium tuberculosis (100 μg) in mineral oil [complete Freund's adjuvant used (CFA)] into the plantar surface of the hind paws. Simvastatin(40 mg/kg), atorvastatin(10 mg/kg), ezetimibe(10 mg/kg), ezetimibe(10 mg/kg) + simvastatin(20 mg/kg or 40 mg/kg) were given intragastrically and the treatment began on the day of CFA injection and continued daily up to the 28th day after arthritis induction. The ezetimibe + simvastatin combination was more effective in reducing the inflammatory response in arthritic rats than in atorvastatin, simvastatin, or ezetimibe monotherapy. The observed effect seems to be cholesterol-independent as there were no changes in plasma cholesterol levels. In spite of the benefits on joint lesions, treatment with ezetimibe + simvastatin combination caused a marked increment in liver, kidneys, spleen size, and plasma transaminases activities. Therefore, animals treated with the ezetimibe(10 mg/kg) + simvastatin(40 mg/kg) combination were also submitted to liver perfusion experiments. In this regard, ezetimibe + simvastatin did not improve the liver metabolic alterations seen in control arthritic rats, on the contrary, a worsening was observed in liver production of glucose from alanine, as well as in oxygen uptake. All of these metabolic changes appear to be induced by treatment with ezetimibe + simvastatin combination, as the same metabolic effects were observed in normal and treated arthritic animals.

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.
