The effect of Allopurinol (ALLO), on adjuvant arthritis was studied in rats and compared with the effect of indomethacin (IND). Drugs were given by intraperitoneal injection for each day beginning from the day of adjuvant injection (day 0) and continued until the 16th day. Paw swelling was measured on days 4, 17 and 29, and secondary lesions were assessed on days 17 and 29. Polymorphonuclear leukocyte (PMNs) count was also evaluated on day 17. ALLO, at relatively high doses (25-50 mg/kg), reduced paw swelling of the adjuvant-injected extremity on day 4; lower doses (6.25-12.5 mg/kg), however, elicited the same inhibitory effect on day 17. IND (0.25 mg/kg) also prevented paw swelling on days 4 and 17. Both ALLO and IND reduced the secondary lesions on days 17 and 29 and prevented the increase in polymorphonuclear leukocytes during the development of adjuvant arthritis. Possible mechanisms of the antiinflammatory effect of ALLO in adjuvant arthritis are discussed.

Gout is a systemic metabolic disorder caused by elevated uric acid (UA) levels, affecting over 1% of the population. The most common complication of gout is gouty arthritis (GA), characterized by swelling, pain or tenderness in peripheral joints or bursae, which can lead to the formation of tophi. At present, western medicines like colchicine, febuxostat and allopurinol are the primary treatment strategy to alleviate pain and prevent flare-ups in patients with GA, but they have significant side effects and increased mortality risks.

Background: Knee loading is associated with the severity and progression of knee osteoarthritis, while knee pain contributes to reduced functional ability and quality of life. In this systematic review, we quantified knee loading and knee pain during different daily activities in people with knee osteoarthritis and explored methodological reasons for differences between studies.
Methods: PubMed, Web of Science, Scopus, and manual searches were performed up to July 2024, to retrieve studies measuring knee loading and knee pain in walking, sit-to-stand and stair climbing of people with knee osteoarthritis.

This study reports the preparation of hydrogels (HG) made with xanthan gum (XG) and ƙ-carrageenan (KC) polysaccharides containing ketoprofen (KET)-loaded nanoemulsions (NK) and their evaluation in a rheumatoid arthritis (RA) model. The nano-based HGs exhibited nanometric-sized droplets (~ 100 nm), an acidic pH (5.10-6.

Background: Hyperbaric Oxygen Therapy (HBO) is a treatment modality that exposes patients to 100% oxygen at higher atmospheric pressures. Recently, HBO has emerged as a potential therapeutic option for various liver diseases, offering advantages such as improved tissue oxygenation, anti-inflammatory effects, enhanced wound healing, and potential hepatoprotective properties. Understanding the benefits of HBO in liver diseases can pave the way for novel therapeutic strategies and improved patient outcomes.

This study attempted to explore the molecular mechanism of Epimedium herb (EH) on rheumatoid arthritis (RA) treatment. We employed network pharmacology, molecular docking, and HPLC analysis to investigate the molecular mechanisms underlying the efficacy of EH in treating RA. To assess the efficacy of EH intervention, RA fibroblast-like synoviocytes (RA-FLS) and collagen-induced arthritis (CIA) mouse models were utilized.
