Abstract

Bowman-Birk inhibitor concentrate (BBIC) is asoybean extract enriched in the BowmanBirk inhibitor, aprotein protease inhibitor. The Bowman-Birk inhibitorcan inhibit proteases released from inflammation mediating cells and suppress superoxide anionradical secretion from immunocytes. This studyinvestigates the ability of Bowman-Birk inhibitorconcentrate to inhibit colon inflammation in the dextransulfate sodium model of ulcerative colitis, aninflammatory bowel disease. When compared to mice on astandard diet, mice given food supplemented with 0.5%BBIC during and after dextran sulfate sodium treatment showed suppression of three of four scoredhistopathological inflammation criteria (P < 0.01),total histopathological score (P < 0.01), a 15% lowermortality rate (P < 0.01), and a delayed onset of mortality. We conclude that dietaryBowman-Birk inhibitor concentrate can beneficiallyaffect dextran sulfate sodium-treated mice and may beuseful in the treatment of human inflammatory boweldiseases, particularly ulcerative colitis.
