Effect of aqueous extract of Aegle marmelos unripe fruit on inflammatory bowel disease.

ObjectiveThe present study was designed to evaluate the effect of Aegle marmelos unripe fruit extract (AMFE) on inflammatory bowel disease (IBD) in Wistar albino rats.Materials and methodsEffect of AMFE was studied on acetic acid induced ulcerative colitis (1 ml of 4% acetic acid solution, transrectal) and indomethacin-induced enterocolitis (10 mg/kg, single dose, p.o) in Wistar albino rats. The extract was administered orally at different dose of 150, 200 and 250 mg/kg body weight. Disease pathogenesis was assessed by measuring disease activity index (DAI), macroscopic score, microscopic score, mesenteric mast cell protection, superoxide dismutase (SOD), and malonaldehyde (MDA) levels in the above two models.ResultsThe results showed a dose dependent decrease in intestinal inflammation following treatment with AMFE. Significant protection in mast cell degranulation was observed in acetic acid and indomethacin-induced IBD models. Treatment with AMFE significantly decreased the MDA levels and increased SOD activity.ConclusionIn our study, AMFE produced anti-inflammatory, antioxidant, and mast cell stabilizing effects demonstrating protective effect in inflammatory bowel disease.
