The aim of this experiment was to investigate the infl uence of inulin administration on chemopreventive and inflammatory markers in dimethylhydrazine induced colorectal cancer development in rats. A group of 30 Sprague-Dawley rats was divided into a control group (CG), a group with dimethylhydrazine (DMH), and a group given dimethylhydrazine combined with the prebiotic (DMH+PRE). Dimethylhydrazine injection significantly (p<0.001) elevated the immunoreactivity chemopreventive markers COX-2, NFκB, iNOS, elevated serum and jejunal mucosa levels of proinfl ammatory cytokine IL-2, and decreased serum and jejunal mucosa levels of regulatory cytokine IL-10.
