Objectives: To study the anti-arthritic activity of Pathyadya Churna ethanol extract (PCE) in rats.
Materials and Methods: Formaldehyde (2% v/v) or complete Freund's adjuvant (CFA 0.l mL) was injected in the left hind paw of male Wistar rats to develop arthritis. These rats were treated with three doses (135, 270, and 540 mg/kg) of PCE and one dose (10 mg/kg) of indomethacin. Anti-arthritic activity of the extract was assessed by noting paw volumes, rheumatoid factor (RF), blood parameters, and histological changes.
Results: PCE treatment reduced paw swelling in arthritis caused by both formaldehyde and CFA. In CFA-treated rats, a significant decrease (P < 0.001) was seen in hemoglobin (13.92 g/dL to 9.97 g/dL), red blood cell count (7.32 million/mm3 to 6.58 million/mm3), and packed cell volume (44.04% to 30.56%). There were also significant (P < 0.001) elevations in white blood cell count (8220/–11,420/mm3), platelets (2.46–4.15 lakhs/mL), erythrocyte sedimentation rate (3.76–8.03/60 min), RF (7.17–26.77 IU/mL), triglycerides (71.69–96.60 mg/dL), total cholesterol (96.85–145.05 mg/dL), low-density lipoprotein (53.11–109.60 mg/dL), and very low-density lipoprotein (14.34–19.32 mg/dL). In CFA-induced arthritic rats, high-density lipoprotein decreased significantly (29.40 mg/dL to 16.13 mg/dL). Marked changes were noted in the histology of ankles. Treatment with PCE significantly reversed all these hematological and histological changes in a dose-dependent manner.
Conclusions: PCE has a significant anti-arthritic activity in rats and is free from toxic effects.
