Abstract
The objective of this study was to investigate the effect of the probiotic strain Lactobacillus plantarum LS/07 and prebiotic inulin on the activity of β-glucuronidase, transcription nuclear factor kappa B (NFκB), myeloperoxidase (MPO), cytokine levels (IL-6, IL-8, IL-13), and counts of coliforms and lactobacilli in rats with dextran sulphate sodium (DSS) induced acute colitis. Sprague-Dawley rats were divided into groups: control (C), acute colitis (AC), prebiotic (Pre), and probiotic (Pro). Dextran sulphate sodium induced inflammatory process in the colonic tissue, increased the activity of β-glucuronidase (P < 0.05), increased counts of coliforms, decreased lactobacilli counts (P < 0.05), and activated production of the measured indicators NFκB, MPO, IL-6, IL-8, except of IL-13. Diet supplemented with L. plantarum and inulin alleviated DSS induced inflammatory process by inhibiting production of IL-6, IL-8, activities of NFκB and MPO, and by stimulation of IL-13. These results indicate that the dietary intake of Lactobacillus plantarum LS/07 and inulin suppressed the expression of markers playing an important role in the inflammatory process, which predisposes their use in prevention or treatment of acute colitis.
