Rheumatoid arthritis (RA) is a complex disease including autoimmune disorder and resulting in inflammation. It also shows progressive proliferation of synoviocytes, and these synoviocytes destroys articular structure. In order to understand the mechanism of this abnormal proliferation of RA-originated synoviocytes in molecular level, we analyzed the gene expression profiles by using DNA chips t...

Rheumatoid arthritis is a chronic, destructive, autoimmune joint disease that affects one to two million Americans (or approximately 1% of the population of the United States). This disease can strike at any age and affects roughly three times as many women as men (http://ww2. arthritis.org/conditions/DiseaseCenter/RA/ra_who.asp). Symptoms include joint stiffness, swelling, and pain, as well as...

By oxymetry and electron paramagnetic resonance (EPR), we investigated the effects of repeated anoxia/re-oxygenation (A/R) periods on the respiration and production of free radicals by synoviocytes (rabbit HIG-82 cell line and primary equine synoviocytes) and equine articular chondrocytes. Three periods of 20 min anoxia followed by re-oxygenation were applied to 10(7)cells; O(2) consumption was...

As in Iranian traditional medicine, bee venom (BV) is a promising treatment for the rheumatoid arthritis (RA) which is considered as a problematic human chronic inflammatory disease in the present time. Smoking is considered to be a major risk factor in RA onset and severity. The main aim of this study is to investigate the effects of BV on cigarette smoke-induced inflammatory response in fibro...
