The metabolic response to colitisA new study being published by the American Physiological Society (www.The-APS.org) finds that the body responds differently to colitis (inflammation of the colon) based on whether the disease is acute (sharp and brief) or chronic (long-term). Researchers, using an experimental mouse model of colitis, discovered that the effects of acute colitis were associated with decreased body weight, food intake, and body fat content. Chronic colitis was........Go to the Health-blog (Added on 2/26/2007 7:53:38 PM)
