    Abstract:
    Drynaria quercifolia (L.) J. Sm., is an ethnomedicinal plant used widely in Tamil Nadu to treat arthritis. The present study was aimed to evaluate the traditional claim of D. quercifolia rhizome water extract in adjuvant induced arthritic animals. Anti-arthritic effect was studied by assessing the levels of lysosomal enzymes, protein bound carbohydrates, urinary degradative collagen and serum cytokines on control and adjuvant induced arthritis. The paw swelling and body weight were also analyzed. The levels of ROS and lysosomal enzymes in neutrophils of control and adjuvant induced animals were also estimated. D. quercifolia rhizome water extract at doses of 100 and 200mg/kg reduced the paw thickness and elevated the mean body weight of arthritic rats. The treatment with extract showed a significant reduction in the levels of plasma and liver lysosomal enzymes as well as protein bound carbohydrates and urinary degradative collagen levels. The treatment reduced the levels of ROS and lysosomal enzymes in neutrophils significantly. The significant reduction in the levels of serum pro-inflammatory cytokines (TNF-α and IL-1β) and the increment in the levels of anti-inflammatory cytokine (IL-10) were also observed by the treatment. The present study supports the traditional claim of using D. quercifolia to treat rheumatism.
