Therapeutic Effect of Ficus lacor Aerial Roots of Various Fractions on Adjuvant-Induced Arthritic Rats.

The present study was carried out to evaluate antiarthritic potential and phytochemical screening of various extracts of Ficus lacor aerial roots. The antiarthritic activity was evaluated by adjuvant-induced arthritis at the dose of 50 and 100 mg/kg body weight and the standard drug used was indomethacin. The extracts administered in higher doses reduced the lesions to a greater extent showing a dose-dependent decrease in lesions comparable with standard drug indomethacin. The extracts of FLPE and FLET showed significant increase in body weight as compared to arthritic control group as well as an increase in liver weight, a decrease in liver weight, and an increase in spleen weight in arthritis control. The extracts of FLPE and FLET showed significant decrease in WBC count, increase in hemoglobin contents, and RBC count as compared to control group. FLEA and FLCF were not able to produce a significant effect. There was significant reduction in production of IL-1 and TNF- α level between model group and control group in serum. In conclusion, we demonstrate that, at 100 mg/kg body weight, doses of FLPE and PLET extracts were highly effective in preventing and suppressing the development of adjuvant-induced arthritis.
