Experimental evaluation of anti-inflammatory effect of topical application of entada phaseoloides seeds as paste and ointment

AIMS: The study was to study the anti-inflammatory effect of topical application of different formulations of seed pulp of entada phaseoloides. METHOD AND MATERIAL: After removing the shell, entada phaseoloides seeds were powdered. Paste was prepared with water and ointment with polyethylene glycol & Carbowax 3350. 32 Wister rats of either sex weighing 140-200 gram were divided into four groups, Group-I vehicle, Group-II entada phaseoloides paste, Group-III entada phaseoloides Ointment, Group-IV Diclofenac sodium Ointment. Arthritis was induced by injecting 0.1ml Complete Freund's adjuvant in sub plantar region of the left hind paw. Drug treatment was started on the same day and given for 12 days. Paw volume was measured with Plethysmometer on day 0, 1, 5, 12 and 21 for both the paws. Bodyweight and Gait was observed throughout the study. RESULTS: Localized inflammatory reaction developed in all the rats in 24 hours. In control group, there was no resolution of swelling even in 21 days. Both EP formulations showed significant (P < 0.001) anti-inflammatory activity as compared to control. entada phaseoloides ointment was equi-effective to that of Diclofenac sodium on 12(th) day. entada phaseoloides paste was significantly (P < 0.05) more effective than Diclofenac sodium on 21(st) day. CONCLUSION: Both the formulations of entada phaseoloides have anti-inflammatory activity and entada phaseoloides paste is significantly more effective than diclofenac sodium.
