title: Suppressive activity of a fermented grain food product on dextran sulfate sodium-induced experimental colitis in mice.
abstract: Oxidative stress has been shown to play pivotal roles in the onset of inflammatory bowel disease. We evaluated the effects of a dietary anti-oxidant, Antioxidant Biofactor (AOB), a processed grain food, on dextran sulfate sodium (DSS)-induced colitis in mice. Female ICR mice were fed a diet containing 0.1% or 1% AOB for 2 weeks, during which they were given 5% DSS in drinking water for the latter 1 week to induce colitis. A diet containing 1% AOB, but not that with 0.1% AOB, attenuated DSS-induced body weight loss and colon shortening (each, P < 0.05), and dramatically improved colitis histologic scores. In addition, DSS-induced increases in colonic mucosal IL-1beta, but not TNF-alpha, protein levels were significantly abrogated in 1% AOB-fed mice (P < 0.05). Further, 1% dietary AOB abolished the expression of IL-1beta mRNA levels in colonic mucosa (P < 0.01). Our results suggest that AOB is effective for the prevention of DSS-induced colitis in mice.
