Abstract
Despite the high global prevalence, rheumatoid arthritis lacks a satisfactory treatment. Hence, the present study is undertaken to design and synthesize novel anti-inflammatory compounds. For this, quinoline and anthranilic acid, two medicinally-privileged moieties, were linked by pharmacophore hybridization, and following their computational assessments, three hybrids 5a-c were synthesized in good over all yields. The in vitro and in vivo anti-inflammatory potential of these hybrids was determined by anti-denaturation and anti-proteinase, and carrageenan-induced paw edema models. The computational studies of these hybrids revealed their drug-likeness, optimum pharmacokinetics, and less toxicity. Moreover, they demonstrated high binding affinity (-9.4 to -10.6 kcal mol-1) and suitable binding interactions for TNF-α, FLAP, and COX-II. A three-step synthetic route resulted in the hybrids 5a-c with 83-86% yield of final step. At 50 μg mL-1, the antiprotease and anti-denaturation activity of compound 5b was significantly higher than 5a and 5c. Furthermore, 5b significantly reduced the edema in the right paw of the rats that received carrageenan. The results of this study indicate the medicinal worth of the novel hybrids in treating inflammatory disorders such as rheumatoid arthritis.

Abstract
Background To date, a regional approach using local anesthetics has become a popular analgesic method for arthroscopy. The optimal postoperative analgesia method for shoulder arthroscopy is still debated. Objective This study was designed to evaluate the effect and safety of using ketorolac in combination with a multimodal drug regime (ropivacaine, morphine, and triamcinolone acetonide) after shoulder arthroscopy. Methods A total of 60 patients were included in a pilot study and patients were randomized into an experimental group (n=30) and a control group (n=30). The following parameters were used to evaluate pain relief levels postoperatively: the Visual Analog Scale (VAS) at 1, 3, 6, 12, 24, and 48 hours postoperatively, morphine consumption, and initial analgesic desired time. Complications were also recorded. Results Except for 1 hour postoperatively, patients in the experimental group experienced lower VAS scores during the first 48 hours postoperatively (P<0.05). The VAS score in both groups increased after 3 hours postoperatively and peaked at 12 hours postoperatively (2.54±0.86 vs 3.25±1.18). The VAS scores on movement in the experimental group were lower than those in the control group at 24 or 48 hours postoperatively (P=0.004, 0.001). A total of 18 (60.0%) patients in the experimental group required no additional analgesia, compared with 10 (33.3 %) in the control group (P=0.035). The mean rescue analgesia was 11.40±5.56 mg in the experiment group, while 16.57±8.48 mg in the control group (P=0.016). The initial analgesic desired time was delayed significantly in the experimental group (16.50±14.57 hours vs 8.9±6.32 hours, P=0.000). Conclusion Adding ketorolac to intra-articular injection analgesia is a safe and effective method to improve pain relief after shoulder arthroscopy, and further prospective controlled trials are necessary to allow definite treatment recommendations.

Abstract
BACKGROUND AND OBJECTIVES Tenoxicam is widely used in osteoarthritis treatment and we aimed to compare the effectivity of oral and intra-articular administration of tenoxicam in osteoarthritis treatment. METHODS This study was performed between 2011 and 2012 by retrospectively analyzing and comparing the findings of 60 patients who were clinically and radiologically diagnosed with knee degenerative osteoarthritis in Bünyan state hospital pain policlinic. 60 patients included in the study were divided into two groups. The first group (tenoxicam IA, n=30) included patient findings of those subjected to intra-articular injection of 20mg tenoxicam to the knee once a week for three weeks and the second group (oral tenoxicam, n=30) included patients who were administered 20mg oral tenoxicam once a day for three weeks. All patients were clinically evaluated pre-treatment and in the 1st week, 1st month and 3rd month post-treatment according to specified criteria. RESULTS AND CONCLUSIONS Twenty two of 60 patients included in the study were male and 38 were female. In both groups significant improvements were detected in all of the observed parameters: visual analog scale, Western Ontario McMaster Osteoarthritis Index (pain, physical activity, knee stiffness) and Lequesne index scores and in the evaluations performed in 1st week, 1st month and 3rd month with respect to pre-treatment values. Besides, a better compliance to treatment and gastrointestinal system tolerability in tenoxicam IA group was also observed. Intra-articular tenoxicam administration could be thought as an alternative treatment method in patients with knee osteoarthritis who cannot use oral tenoxicam especially due to systemic gastrointestinal system side effects and those who have difficulties in adapting to treatment.

Abstract
PURPOSE NSAIDs and analgesic drugs are used intra-articularly after knee arthroscopy for pain relief. However, synovial effusion is still a common cause of delayed physical therapy. The aim of this study was to demonstrate the beneficial effect of intra-articular injection of Tenoxicam on knee effusion after arthroscopy. METHOD This was a prospective non-randomized study on 134 patients with a mean age of 36.7 years. Knee arthroscopy on a day-case basis was performed; normal saline was used for irrigation. At the end of the procedure, fluid was aspirated from the knee joint and 20 ml of Tenoxicam diluted with 20 ml of 0.9% normal saline was injected into the knee five minutes before deflation of limb tourniquet. The same surgeon performed clinical examination for knee effusion 14 days postoperatively. RESULTS Encountered pathologies included meniscal injury, degenerative arthropathy, synovial plica and ACL rupture. Knee effusion developed in 15.7% of the patients, particularly in those with degenerative arthropathy (p = 0.006) and meniscal lesions (p = 0.06). CONCLUSION Intra-articular Tenoxicam is a simple method for the prevention of postoperative knee effusion. Degenerative arthropathy and meniscal lesions are major risk factors for post arthroscopy knee effusion.

Abstract
The objective here was to evaluate the acute effects of induced arthritis on synovial fluid (SF) levels of matrix metalloproteinases (MMP) -2, -8 and -9 in horses. To evaluate MMP-2 and -9 activities and the effect of non-steroidal anti-inflammatory drug (NSAID) bufexamac during remission from acute arthritis. Aseptic arthritis was induced in 24 Standardbred horses using 20 mg of amphotericin B as a single intra-articular (IA) injection in the right intercarpal joint. After 1 week and 2 weeks, horses were treated intra-articularly with 10, 20, or 40 mg of bufexamac suspension or with sterile saline solution as control. SF was sampled prior to induction and at weekly intervals for 5 weeks. Fluids were evaluated for MMP-2 and MMP-9 activity by gelatin zymography or for MMP-8 immunoreactivity by Western Blotting. IA injection of amphotericin B consistently resulted in significant increase in the immunoreactivity of MMP-8 and activity of both the latent and the active forms of MMP-2 and -9, among which the active form of MMP-2 increased the most. MMP-9 levels declined to pre-induction levels within 2 weeks, whereas levels of MMP-2 remained still high after 5 weeks. Treatment with bufexamac did not significantly affect levels of gelatinolytic MMP. Results suggest that after acute arthritis of horses, elevated MMP activity is present in the joint, for several weeks, to a degree that could promote cartilage degradation, and treatment with the NSAID bufexamac is not likely to affect that. Furthermore, analysing levels of MMP-9 activity and especially levels of active forms of MMP-2 activity may be valuable to predict the time of occurrence of arthritis in horses.

Abstract
This study was designed to compare efficacy of local administration of a nonsteroidal anti-inflammatory drug with systemic administration in patients with osteoarthritis (OA) of the knee. For this purpose, intra-articular tenoxicam and oral tenoxicam therapies were applied and the improvement in control of pain and physical functioning were evaluated. A total of 69 patients with OA of the knee were randomized into three groups. Patients in the first group (41 knees of 23 patients) were treated for 1-3 weeks with once weekly intra-articular injection of tenoxicam 20 mg. Patients in the second group (45 knees of 26 patients) received 20 mg/day tenoxicam orally for 3 weeks and only physical exercises were applied to the third group (32 knees of 20 patients). Physical examination of the knee joint, Western Ontario and McMaster Universities Index and the Lequesne Algofunctional Index were used as outcome measurements at baseline, and the 1st, 3rd and 6th months. More significant improvement in pain and disability parameters was observed in groups 1 and 2 than group 3 compared with baseline measures. Among the patients' responses a few of the differences were statistically significant, more in favour of tenoxicam, and tenoxicam seemed to be superior to exercise alone especially at the final evaluation. There was no significant difference between the oral and intra-articular tenoxicam treatment regimens. The results of this study showed that treatment of OA of the knee with intra-articular tenoxicam is as effective as that with oral tenoxicam. It can be thought that intra-articular administration can be preferred to oral therapy due to minimal possibility of systemic side effects.

Abstract
Inhibition of type IV phosphodiesterase (PDE IV) activity reduces the production of various proinflammatory cytokine and suppresses neutrophil activation. Nonsteroidal anti-inflammatory drugs such as aspirin induce gastric mucosal lesions. In the pathogenesis of aspirin-induced gastric mucosal lesion, the contributions, of activated inflammatory cells and proinflammatory cytokine production are critical. The specific PDE IV inhibitor rolipram is known to be a potent inhibitor of inflammation by increasing intracellular cyclic AMP in leukocytes. The aim of the present study was to determine whether rolipram can ameliorate aspirin-induced gastric mucosal lesions in rats and whether the agent can inhibit the inrease in neutrophil accumulation and the production of proinflammatory cytokines. Gastric lesions were produced by administration of aspirin (200 mg/kg) and HCI (0.15 N; 8.0 ml/kg). Rolipram was injected 30 min before aspirin administration. The tissue myeloperoxidase concentration in gastric mucosa was measured as an indicat or of neutrophil infiltration. The gastric mucosal concentrations of tumor necrosis factor-alpha (TNF-alpha) and interleukin-1beta (IL-1beta) were determined by ELISA. The intragastric administration of aspirin induced multiple hemorrhagic erosions in rat gastric mucosa. Gastric mucosal lesions induced by aspirin were significantly inhibited by treatment with rolipram. The mucosal myeloperoxidase concentration was also suppressed by rolipram. Increases in the gastric content of TNF-alpha and IL-1beta after aspirin administration were inhibited by pretreatment with rolipram. We demonstrated that the specific type IV PDE inhibitor, rolipram, could have a potent antiulcer effect, presumably mediated by its anti-inflammatory properties.

Abstract
Analgesics are commonly injected intra-articularly for analgesia after arthroscopic surgery, especially of knee joints. The aim of this study was to research the effects of ketorolac and morphine on articular cartilage and synovial membrane. This study used rabbit right and left hind knee joints. The treatments, saline, morphine, or ketorolac, were administered intra-articularly 24 h after injection, and 5 joints from animals in each drug group were chosen randomly to form Group I and subgroups of Group I. The same procedures were applied after 48 h and 10 days of injection to form Groups II and III, respectively, and subgroups of these groups. Knee joints were excised and a blinded observer evaluated the histopathology according to inflammation of the articular cartilage, inflammatory cell infiltration, hypertrophy, and hyperplasia of the synovial membrane. No histopathological changes were found in the control groups. In the ketorolac and morphine groups, there were varying degrees of synovial membrane inflammatory cell infiltration and minimal, mild, or moderate synovial membrane cell hyperplasia or hypertrophy. Except for the ketorolac group at 24 h, both ketorolac and morphine groups showed more histopathological changes than controls (p < 0.05). Morphine and ketorolac both cause mild histopathological changes in rabbit knee joints, morphine causing more than ketorolac, but both of the drugs can be used intra-articularly with safety.

Abstract
OBJECTIVE To investigate the influence of the use of various types of nonsteroidal antiinflammatory drugs (NSAIDs) on progression of osteoarthritis (OA) of the hip and knee. METHODS In 1,695 subjects (2,514 hips) and 635 subjects (874 knees) ages 55 years and older from the Rotterdam Study, radiographs of the hip and knee at baseline and followup (mean followup time 6.6 years) were evaluated. Radiologic OA (ROA) progression was defined as a minimum increase of 1 in the Kellgren/Lawrence grade or incident joint replacement at followup. The associations between the different types of NSAIDs and progression of ROA were assessed using multivariate logistic regression analysis. RESULTS Those subjects who were receiving diclofenac >180 days had a 2.4-fold increased risk (95% confidence interval [95% CI] 1.0-6.2) of progression of hip ROA and a 3.2-fold increased risk (95% CI 1.0-9.9) of knee ROA, compared with those considered short-term users (diclofenac for 1-30 days). These associations were adjusted for age, sex, body mass index, baseline ROA, followup time, and defined daily dosage. CONCLUSION These data suggest that diclofenac may induce accelerated progression of hip and knee ROA. Whether this occurs because of a true deleterious effect on cartilage or because of excessive mechanical loading on a hip following pain relief remains to be investigated.

Abstract
BACKGROUND In periodontitis, matrix metalloproteinase-3 (MMP-3, stromelysin 1) is present at increased levels in active disease sites compared to inactive or healthy sites, and the levels are correlated with clinical parameters and associated with progression of the disease. Interleukin (IL)-4 has been shown in human skin and synovial fibroblasts and articular chondrocytes to suppress IL-1-induced expression of MMP-3, but this has not been shown in human gingival fibroblasts. The objective of this study is to determine the effects of IL-4 on the IL-1-induced expression of MMP-3 in human gingival fibroblasts isolated from patients with periodontitis. METHODS Northern blot analysis was performed to determine the effects of IL-4 on the IL-1 induction of MMP-3 mRNA. MMP-3 protein levels were determined by enzyme-linked immunosorbent assay (ELISA), and prostaglandin E2 (PGE2) levels were measured by enzyme immunoassay (EIA). DNA binding of activator protein (AP)-1 and nuclear factor (NF)-kappaB was assessed by electrophoretic mobility shift assay (EMSA). RESULTS Northern blot analysis revealed that co-incubation of gingival fibroblasts with IL-1 and IL-4 resulted in a significant decrease in MMP-3 mRNA levels compared to IL-1 alone, with a concomitant decrease in protein levels. This inhibition is dose-dependent, and is apparent as early as 3 hours after stimulation. IL-1-induced production of PGE2 was not affected in four of six cultures isolated from different individuals. Addition of exogenous PGE2 had no effect on the suppressive effects of IL-4. DNA binding of transcription factors AP-1 and NF-kappaB was not affected by IL-4. CONCLUSIONS IL-4 inhibits the IL-1 induction of MMP-3 in human gingival fibroblasts isolated from patients with periodontitis. This effect is independent of PGE2 and is not due to inhibition of the DNA binding activity of known transcription factors binding to the MMP-3 promoter.

Abstract
Inhibition of type IV phosphodiesterase activity is beneficial in various inflammation mediated by its function to suppress the production of inflammatory cytokines in inflammatory cells. Nonsteroidal anti-inflammatory drugs (NSAIDs) such as indomethacin are well known to develop gastric mucosal lesion. As pathogenesis of indomethacin induced gastric mucosal lesion, activation of neutrophils and inflammatory cytokine production play critical roles. However, the effect of phosphodiesterase inhibitors on development of gastric mucosal lesion has not been reported. In the present study, we examined the effect of specific type IV phosphodiesterase inhibitor (rolipram) on NSAIDs-induced gastric mucosal lesion. Also, we examined the effect of rolipram on tissue prostaglandin E2 (PGE2) production. Indomethacin-induced gastric mucosal injury was produced by the intragastric administration of indomethacin (30 mg/kg). Rolipram was injected to the rats intraperitoneally 30 min before the indomethacin administration. Ulcer index and tissue myeloperoxidase (MPO) activity of the gastric mucosa was evaluated. The gastric concentration of PGE2 was determined by RIA. Gastric mucosal lesion induced by indomethacin was significantly inhibited with treatment of rolipram. Mucosal MPO activity was also suppressed by administration of rolipram. Gastric mucosal PGE2 concentration was not affected by intraperitoneal injection of rolipram. Based on these data, the beneficial effects of rolipram on indomethacin-induced gastric mucosal injury may be attributed to its anti-inflammatory properties.

Abstract
Two studies were conducted under laboratory conditions with 16 dogs to investigate the analgesic effectiveness of a low dose of ketoprofen in a short-term sodium urate crystal-induced synovitis model of arthritis. The effect of the treatment, defined as the improvement in peak vertical force weight bearing was evaluated in the first study at three dose levels. A single oral dose of 0.25 mg/kg ketoprofen was significantly better (P < 0.01) than the control (0 mg), but doses of 0.5 and 0.75 mg/kg did not improve the dogs' weight bearing further. The second study investigated the efficacy and safety of the 0.25 mg/kg dose administered daily for 30 days. The beneficial effects of ketoprofen at this dose were constant, with the treated dogs bearing 89.1 per cent of the baseline vertical force four hours after the induction of arthritis on day 1 and 92.2 per cent on day 29, compared with 42 per cent and 34 per cent of the baseline in the untreated dogs. No gastrointestinal or other side effects were observed during the treatment.

Abstract
1. Since nonsteroidal anti-inflammatory drugs (NSAIDs) may impair the ability of the chondrocyte to repair its damaged extracellular matrix, we explored the changes in the metabolism of newly synthesized proteoglycan and hyaluronan (HA) molecules produced by aceclofenac, diclofenac and meloxicam in human osteoarthritic (OA) cartilage. 2. Explants were sampled from the medial femoral condyle and were classified by use of the Mankin's histological-histochemical grading system. Cartilage specimens exhibited moderate (M) OA in 20 subjects and had severe (S) OA in 20. 3. Cartilage explants were pulsed with [-3H]-glucosamine and chased in the absence or in the presence of 0.3 - 3 microg ml(-1) of either aceclofenac, diclofenac or meloxicam. After papain digestion, the labelled chondroitin sulphate ([-3H]-proteoglycans) and [-3H]-HA molecules present in the tissue and media were purified by anion-exchange chromatography. 4. In cartilage with MOA and SOA, the metabolic balance of proteoglycan and HA was unaffected by diclofenac. In contrast, and in a dose-dependent manner, aceclofenac and meloxicam both increased the synthesis of proteoglycans and HA in explants with MOA and SOA; these two NSAIDs also reduced significantly the net loss of [-3H]-proteoglycans and [-3H]-HA molecules from cartilage explants. 5. The data obtained in short-term in vitro cultures indicate that, at the concentrations found in synovial fluid, aceclofenac and meloxicam may exert a favourable effect on the overall metabolism of proteoglycans and HA in cartilage with MOA and SOA.

Abstract
OBJECTIVE The efficacy of glucosamine sulfate (GS) in the symptomatic treatment of patients with osteoarthritis (OA) is suggested to be mediated by still unknown effects on the altered OA cartilage. DESIGN Using human OA chondrocytes in culture, the effects of GS on protein synthesis, caseinase, collagenase, phospholipase A2 (PLA2) and protein kinase C (PKC) activities as well as production of nitric oxide and cyclic AMP were studied in both cells and culture medium. RESULTS GS significantly reduced PLA2 activity, and more modestly collagenase activity, in the OA chondrocytes in a dose-dependent manner. By contrast, PLA2 and collagenase activity of the culture medium was not modified. No effects on caseinase activity was seen. GS significantly and dose-dependently increased protein synthesis. GS did not modify nitric oxide and cAMP production but significantly increased PKC production. CONCLUSION GS modified cultured OA chondrocyte metabolism by acting on PKC, cellular PLA2, protein synthesis and possibly collagenase activation. Extrapolation of the effect to the in-vivo situation remains hypothetical but they might represent some possible mechanisms of action of the drug in human.

Abstract
PURPOSE Non Steroidal Anti-inflammatory drugs have a well documented benefit in the relief of postoperative pain. This study was designed to compare the analgesic effect of intra-articular tenoxicam 20 mg with intravenous tenoxicam on postoperative pain in 88 patients undergoing day case knee arthroscopy. METHODS A prospective, double blind, randomized trial was performed. All patients received a standard general anesthetic. Patients in group A received 20 mg tenoxicam made up to 40 ml with normal saline intra-articularly (ia) and 2 ml normal saline i.v. Patients in group B received 40 ml normal saline intra-articularly and 2 ml, 20 mg of tenoxicam, i.v. RESULTS Both groups of patients were similar with respect to age, weight, sex and tourniquet inflation time. Patients receiving ia tenoxicam had lower pain scores (at rest and upon movement) at 30, 60, 120 and 180 min postoperatively (0.8+/-0.2 vs. 2.5+/-0.2 at rest and 1.24+/-0.2 vs. 3.4+/-0.2 at movement at 60 min; P< 0.0001). Fewer patients required additional analgesia in the first four hours postoperatively (33% vs. 84%; P<0.00001) and the time to first analgesia (23.7+/-11.2 vs. 9.4+/-0.6; P<0.02) was longer in those receiving ia tenoxicam. CONCLUSION Intra-articular tenoxicam provides superior postoperative analgesia and reduces postoperative analgesic requirements compared with i.v. tenoxicam in patients undergoing day case knee arthroscopy.

Abstract
The in-vitro effects of some non-steroidal anti-inflammatory drugs and some analgesic drugs on collagenase activity were studied by use of a self-quenched fluorogenic esapeptide as substrate. The increased fluorescence signal arising as a result of peptide cleavage by collagenase was recorded and related to the inhibitory potency of the drugs. The effective concentrations in collagenase modulation were also correlated with the levels of the drugs in the plasma and synovial fluids of patients receiving therapeutic doses. Six of the tested drugs, nimesulide, piroxicam, tolmetin, meloxicam, sulindac and sodium meclofenamate, inhibited enzyme activity with IC50 values (concentrations resulting in 50% inhibition) ranging from 1.9 to 28.2 microM and Ki (apparent inhibition constant) ranging from 0.83 to 21.8 microM. Much of the activity was restored after dialysis of the enzyme-drug complex, demonstrating the reversibility of the effect. Although these results indicate that some anti-inflammatory drugs could modulate enzymatic activity involved in the degradation of the extracellular matrix, their possible pharmacological involvement as collagenase inhibitors in collagen degradative diseases remains to be assessed by clinical studies.

Abstract
Loss of articular cartilage, which is the most important pathological lesion occurring in osteoarthritis, has been shown to be enzymatically mediated. The matrix metalloproteinases (MMPs) are a group of enzymes which have been implicated in this degradation of articular cartilage matrix. The use of pharmacological agents to inhibit this catabolic process in the joint is a potential route for therapeutic intervention. The gelatinase MMPs, MMPs-2 and 9, were purified by affinity chromatography from equine cell cultures. The ability of phenylbutazone, flunixin, betamethasone, dexamethasone, methylprednisolone acetate (MPA), hyaluronan, pentosan polysulphate and polysulphated glycosaminoglycan (PSGAG) to inhibit equine MMPs-2 and 9 were assessed by two degradation assays. Whilst some agents did have direct effects on MMP activity, these effects were only obtained at concentrations which were unlikely to be achieved for any length of time in vivo. It is improbable that any pharmacological agent, currently used in the horse, has a significant effect on gelatinase MMP activity.

Abstract
OBJECTIVE To determine the effects of interleukin-4 (IL-4) on IL-1 induction of collagenase (matrix metalloproteinase 1 [MMP-1]) and stromelysin-1 (MMP-3) in human synovial fibroblasts. METHODS Northern blot analysis was performed to determine the effects of IL-4 on IL-1 induction of MMP messenger RNA (mRNA). MMP protein levels were determined by enzyme-linked immunosorbent assay, and prostaglandin E2 (PGE2) levels were measured by enzyme immunoassay. Run-on transcription assays and transient transfection experiments were performed to determine whether the effects of IL-4 occur at the level of transcription. Activator protein 1 (AP-1) binding was assessed by electrophoretic mobility shift assay. RESULTS Northern blot analysis revealed that coincubation of synovial fibroblasts with IL-1 and IL-4 resulted in a significant decrease in both collagenase and stromelysin mRNA levels compared with IL-1 alone, with a concomitant decrease in MMP protein levels. This inhibition is dose dependent, with an IC50 (50% inhibition concentration) for both MMPs of approximately 0.3 ng of IL-4 per ml, and is at least somewhat selective, since IL-1 induction of c-fos mRNA is not affected. Nuclear run-on experiments and transient transfection studies demonstrated that the suppression of IL-1-induced collagenase and stromelysin expression by IL-4 occurs at least in part at the transcriptional level, and that binding of transcription factor AP-1 is not affected. Although IL-1-induced levels of PGE2 are reduced by IL-4, exogenous addition of PGE2 does not abrogate the inhibitory effects of IL-4 on MMP expression. CONCLUSION IL-4 inhibits IL-1 induction of both collagenase and stromelysin, as well as PGE2 production, in human synovial fibroblasts. The inhibition occurs at least in part at the level of transcription, does not affect binding of transcription factor AP-1, and appears to involve a mechanism that is independent of the ability of IL-4 to inhibit production of PGE2.

Abstract
Anti-inflammatory medications have long been prescribed for relief of the pain and discomfort associated with OA. This occurs despite the recognized side effects associated with use of NSAIDs and corticosteroids. Available evidence suggests that NSAIDs provide this relief through a combination of central and peripheral actions. Recent discovery of two isoforms of cyclooxygenase has increased our understanding of NSAID activity and may result in identification of drugs that potentially will have fewer side effects. A review of NSAIDs used in veterinary medicine indicates that relatively little is known regarding their role in treating OA, although controlled studies involving carprofen and etodolac have increased our knowledge of the efficacy of specific NSAIDs used for this purpose.

Abstract
Calcitonin (CT) is a known potent inhibitor of bone resorption but its effect on cartilage enzymatic degradation has been incompletely studied. Salmon CT, at a concentration of 0, 0.1, 0.25, 0.5, 2.5 and 50 ng/ml, was added at 24 or 72 h to the culture medium of chondrocytes from human osteoarthritic hips and knees. The spontaneous collagenolytic activity, measured using a radiolabeled type II collagen, was inhibited by CT in a dose-dependent manner. However, CT had no effect on the total collagenolytic activity assayed after APMA activation. Stromelysin and plasmin activity, measured by degradation of casein and a synthetic substrate, were also unaffected by CT. Chondrocyte phospholipase A2 activity, assayed using a labeled specific substrate, was decreased by CT. Chondrocyte pre-incubation with CT significantly decreased the cell binding of labeled TNF alpha, but did not affect IL-1 beta cell binding. Attachment of chondrocytes on fibronectin was markedly stimulated by CT, while attachment to type II collagen was not. Significant effects were obtained using at least 2 or 5 ng/ml of CT. CT appears to decrease collagenolytic activity by decreasing its activation and/or increasing its inhibition by tissue inhibitors of metalloproteinases (TIMP). CT might act on osteoarthritic chondrocyte activation via mechanisms such as phospholipase A2 activity, human necrosis factor-alpha or fibronectin receptor expression.

Abstract
1. As nonsteroidal anti-inflammatory drugs may impair the ability of the chondrocyte to repair its damaged extracellular matrix, we explored the changes in the metabolism of newly synthesized proteoglycan (PG) and hyaluronan (HA) molecules produced by tenoxicam and aspirin in human normal cartilage explants and in osteoarthritic (OA) cartilage from age-matched donors. 2. Explants were sampled from the medial femoral condyle and were classified by use of Mankin's histological-histochemical grading system. Cartilage specimens were normal in 10 subjects, exhibited moderate OA (MOA) in 10 and had severe OA (SOA) in 10. 3. Cartilage explants were pulsed with [3H]-glucosamine and chased in the absence and in the presence of either aspirin (190 micrograms ml-1) or tenoxicam (4-16 micrograms ml-1). After papain digestion, the labelled chondroitin sulphate ([3H]-PGs) and HA([3H]-HA) molecules present in the tissue and media were purified by anion-exchange chromatography. 4. In normal cartilage as well as in explants with MOA and SOA aspirin reduced more strongly PG and HA synthesis than the loss of [3H]-HA and [3H]-PGs. 5. In normal cartilage, tenoxicam did not affect PG metabolism whereas it reduced HA synthesis in a dose-dependent manner and did not change or even increased the net loss of [3H]-HA. In contrast, in OA cartilage, tenoxicam produced a stronger reduction in the loss of [3H]-PGs than in PG synthesis and this decrease occurred at lower concentrations in cartilage with SOA (4-8 micrograms ml-1) than in cartilage with MOA (8-16 micrograms ml-1). In cartilage with MOA, the metabolic balance of HA was unaffected by tenoxicam whereas in cartilage with SOA, the drug decreased the loss of [3H]-HA and concomitantly did not change or even increased HA synthesis.6. The data obtained in short-term in vitro cultures indicate that aspirin may produce OA-like changes in normal cartilage and is likely to worsen the disease process in OA tissue. On the other hand, although tenoxicam may reduce the HA content of normal cartilage, and, in so doing, may produce OA-like lesions, this drug should not per se accelerate joint failure in OA.

Abstract
OBJECTIVE To compare the relative safety and efficacy of naproxen and acetaminophen in the treatment of osteoarthritis (OA) of the knee. The major outcome measures were radiographic progression and withdrawal from the trial due to lack of efficacy. METHODS One hundred seventy-eight patients with OA of the knee were enrolled in a 2-year prospective, controlled, double-blind multicenter trial and were randomly assigned to receive acetaminophen (ACT) or naproxen (NPX) treatment. RESULTS After 6 weeks of treatment, modest improvement in pain on motion and in physician's global assessment was seen in both the ACT and the NPX groups, and the NPX group also had modest improvement in pain at rest and in 50-foot walk time. Sixty-two patients completed the 2-year study. Among these patients, radiographic progression was similar in the 2 treatment groups. Withdrawal from the trial due to lack of drug efficacy was slightly more frequent among patients in the ACT group (22% versus 16%), but withdrawal due to adverse drug effects was slightly more common in the NPX group (23% versus 18%). CONCLUSION The efficacy of ACT treatment and NPX treatment was similar, although it was slightly better for NPX. The toxicity rate was slightly lower with ACT. However, the high rate of withdrawal in both treatment groups suggests that neither is satisfactory for the treatment of OA.

Abstract
The aim of this study was to examine the effects of 2 nonsteroidal anti-inflammatory drugs (NSAIDs), nimesulide and naproxen, on the proteoglycan matrix breakdown and metalloprotease synthesis of human osteoarthritic cartilage. The results showed that, under in vitro conditions, these 2 NSAIDs could significantly reduce both the degradation of proteoglycan and stromelysin synthesis. However, only nimesulide had the ability to significantly reduce collagenase synthesis. The effectiveness of these drugs on the natural course of osteoarthritis remains to be established by clinical studies.

Abstract
The mechanism(s) of action of NSAIDs and corticosteroids in arthritic diseases has been the subject of intensive investigation in recent years. Although NSAIDs and corticosteroids have many effects, their possible ability to modify the disease course in patients has not been fully documented. In an attempt to characterize the mechanism(s) involved in the effect of some NSAIDs in joint diseases, we investigated the effect of three concentrations within the pharmacological (260 micrograms/ml) and therapeutic (26 and 2.6 micrograms/ml) ranges of tiaprofenic acid in the synthesis and release of interleukin (IL-1) alpha and beta in human OA synovial membranes. The effect of tiaprofenic acid was compared to the effect of two other NSAIDs, sodium salicylate (160 micrograms/ml) and indomethacin (1.5 micrograms/ml), and to a corticosteroid, hydrocortisone (0.725 and 7.25 micrograms/ml). This study was carried out using human OA synovium explants incubated in the presence or absence of LPS. In the absence of LPS and at therapeutic concentration, tiaprofenic acid decreased both the synthesis and release of IL-1 beta. A less marked effect of the drug was noted under LPS treatment, and inhibition of the production/secretion of IL-1 beta was found only at pharmacological concentration. Sodium salicylate and indomethacin did not share this action, and demonstrated either no effect or enhancement of IL-1 beta synthesis, respectively, in the presence of LPS. As expected, hydrocortisone demonstrated a marked decrease on IL-1 alpha and IL-1 beta, both in the presence and absence of LPS. These results bring forth new information on the action of these drugs and their effects on the OA pathophysiological process.
