Sesamum indicum, one of the first recorded plants used for its seeds, is reported to have analgesic, antioxidant, anticancer, anti-obesity as well as hepato and nephro protective activities. The current study evaluated the effects of two doses (400 and 800 mg/kg) of ethanolic extract of S. indicum seeds in Freund's complete adjuvant induced arthritis in rats in comparison with diclofenac and methotrexate by the changes produced in body weight, body temperature, paw volume and spontaneous activity, hemoglobin, erythrocyte sedimentation rate, total white blood cells, red blood cells, Interleukin-6 and Tumor necrosis factor-α as well as joint changes in X-ray and histological changes in joint tissue. Unlike the untreated group, the groups treated with S. indicum showed significant decrease in paw volume, body weight, white blood cell count, erythrocyte sedimentation rate, Interleukin-6 and Tumor necrosis factor-α and an increase in body weight, spontaneous activity, hemoglobin level, and red blood cell count. Histopathological examination showed gross reduction in synovial inflammation and cartilage damage. X-ray revealed significant improvement in joint space. The effect of ethanolic extract of S. indicum was found to be equivalent to methotrexate and greater than diclofenac.

The present study was designed to investigate the anti-inflammatory activity of macrolides and to compare with standard non-steroidal anti-inflammatory drug (NSAID) etoricoxib. This study was conducted in male wistar albino rats by inducing edema with 1% carrageenan. Animals were divided into 5 groups with 6 in each and paw edema volume was measured by digital plethysmograph before and 3hrs after 1% carrageenan administration. Percentage of inhibition of paw edema was calculated. Results showed macrolides having significant anti-inflammatory activity & the anti-inflammatory activity of roxithromycin was almost equally comparable with etoricoxib.
