Abstract

BACKGROUND & OBJECTIVES:

Coriandrum sativum (CS), has been widely used in traditional systems of medicine for treatment of rheumatoid arthritis. However, the mechanism of action for its antiarthritic effects is not clearly known. Therefore, the present study was carried out to evaluate the antiarthritic activity of CS in rats in two experimental models.

METHODS:

The antiarthritic activity of CS seed hydroalcoholic extract (CSHE) was evaluated in adult Wistar rats by using two experimental models, viz. formaldehyde and Complete Freund's adjuvant (CFA) induced arthritis. The expression of pro-inflammatory cytokines (predominantly contributed by macrophages) was also evaluated. TNF- α level was estimated in serum by ELISA method. TNF-R1, IL-1 β and IL-6 expression in the synovium was analysed by immunohistochemistry.

RESULTS:

CSHE produced a dose dependent inhibition of joint swelling as compared to control animals in both, formaldehyde and CFA induced arthritis. Although there was a dose dependent increase in serum TNF-α levels in the CSHE treated groups as compared to control, the synovial expression of macrophage derived pro-inflammatory cytokines/cytokine receptor was found to be lower in the CSHE treated groups as compared to control.

INTERPRETATION & CONCLUSIONS:

Our results demonstrate that the antiarthritic activity of CSHE may be attributed to the modulation of pro-inflammatory cytokines in the synovium. In further studies CSHE could be explored to be developed as a disease modifying agent in the treatment of RA.
