Abstract
Inflammatory bowel disease (IBD) encompasses chronic inflammatory condition of intestine which includes ulcerative colitis (UC) and Crohnâ�?�?s disease (CD). UC is an idiopathic inflammatory disorder characterized by oxidative stress, leucocyte infiltration and up-regulation of pro-inflammatory cytokines. The present study examines the effect of aerial parts of B. sensitivum and amentoflavone on a murine model of ulcerative colitis. UC was induced by intracolonic injection of 3% acetic acid in Wistar rats. B. sensitivum (50 or 100 mg/kg.b.wt), amentoflavone (10 mg/kg.bwt) or reference drug sulfasalazine (100 mg/kg.b.wt) was administrated intra-peritonealy for 5 consecutive days before induction of colitis. In the present study, we demonstrated for the first time that the administration of B. sensitivum (50 mg/kg.b.wt) and amentoflavone (10 mg/kg.b.wt) was found to inhibit colitis by lowering macroscopic score (up to 3.66�?±0.77) as well as significant reduction in lactate dehydrogenase (LDH) (p < 0.01) and myeloperoxidase (MPO) activity (p < 0.01). Furthermore, significant reduction (p<0.01) in mucosal content of lipid peroxidation (LPO), glutathione (GSH), superoxide dismutase (SOD) and nitric oxide (NO) confirms that amentoflavone and B. sensitivum could significantly inhibit colitis. The study showed significant reduction (p < 0.01) in colonic tumor necrosis factor-alpha (TNF-�?±), Interleukin-1-�?² (IL-1�?²) and IL-6 levels as well as the expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) after treatment compared to colitis control group. The histopathological study also confirms the foregoing findings. Treatment with Amentoflavone and B. sensitivum was also able to inhibit the activation and translocation of transcription factors, nuclear factor (NF)-�?ºB subunits (p65/p50). These results suggests that amentoflavone from B.sensitivum exhibits protective effect in acetic acid-induced ulcerative colitis which might be due to its modulation of oxidant/anti-oxidant balance, down-regulation of productions and expressions of pro-inflammatory cytokines, inflammatory mediators and inhibition of NF-�?ºB signal transduction pathways.
