OBJECTIVE Glucosamine sulfate (GS) is a commonly used drug for the treatment of osteoarthritis. The mechanism of the action of this drug does, however, remain to be elucidated. In human osteoarthritic chondrocytes (HOC) stimulated with a proinflammatory cytokine, we studied whether GS could modify the NFkappaB activity and the expression of COX-2, a(More)
BACKGROUND Besides its proinflammatory properties, prostaglandin E(2) (PGE(2)) acts as a regulator of the expression of inducible genes. Inhibition of PGE(2) synthesis might thus result in a paradoxical deleterious effect on inflammation. OBJECTIVE To examine the effect of PGE(2) on monocyte chemoattractant protein-1 (MCP-1) expression in cultured(More)
OBJECTIVE Fibrin deposits adhered to the synovial surface are typical of rheumatoid joints. Since fibrin appears to have a role in arthritis perpetuation our aim was to investigate how these deposits are formed and the consequences of their adhesion to the tissue. METHODS The appearance of fibrin aggregates either free in the synovial fluid or attached to(More)
OBJECTIVE To study the effect of meloxicam (MXC) and diclofenac (DCF) on the recruitment of leucocytes during acute experimental arthritis. METHODS Rabbits with antigen-induced arthritis were treated with MXC, DCF, or not treated. After 48 hours, synovial fluid (SF) leucocyte influx and prostaglandin E(2) (PGE(2)) levels were evaluated. Interleukin 8(More)
The present study was undertaken to investigate, if the non-steroidal anti-inflammatory drug (NSAID) piroxicam (CAS 36322-90-4) Fast-Dissolving Dosage Form (FDDF) can be absorbed in the oral mucosa. Piroxicam FDDF was administrated under the tongue to rats with an oesophagus ligation (OL) to prevent the drug entering the stomach and in turn its absorption(More)
