The aim of presented study was to investigate the influence of Lactobacillus plantarum LS/07 and inulin on the activity of β-glucuronidase enzyme, and counts of coliform and lactobacilli in fresh caecal digesta, cytokine levels (IL-6, IL-8), and trancription nuclear factor kappa beta (NFκB) activities in colon tissue and blood samples of rats with dextran sulphate sodium (DSS) induced acute colitis. The rats were randomly divided into four groups - CG, AC, AC+PRE and AC+PRO. Colitis was induced using of 5% DSS in drinking water for 7d. DSS application increased activity of β-glucuronidase (P < 0.001), increased counts of coliforms, and decreased lactobacilli counts (P < 0.05) in comparison to control group. Serum and tissue levels of IL-6 and IL-8 as well as tissue NFκB activities showed increased expression in acute colitis group. Inulin diet modified counts of microorganims and decreased β-glucuronidase activity, suppressed NFκB activities (P < 0.001) and down regulate synthesis of IL-6 (P < 0.01) in serum and colon tissue and tissue IL-8 (P < 0.05). Lactobacillus plantarum LS/07 decreased β-glucuronidase activity (P < 0.05), levels of IL-6 and IL-8 (P < 0.001). These results were consistent with the addition of histological findings. Our results indicate that dietary intake of Lactobacillus plantarum LS/07 and inulin suppressed expression observed markers, which play an important role in the inflammatory process, which predisposes their use in prevention or treatment of acute colitis.

Prebiotics are defined as selectively fermented food ingredients that induce specific changes in the composition and/or activity in the gastrointestinal microbiota beneficial to the host well-being and health. The aim of the presented experiment was to investigate the effect of a prebiotic applied alone or in combination with Hyppocastani extractum siccum, and Lini oleum virginale in rats with dimethylhydrazine induced colon cancer. Wistar albino rats were fed high fat diet supplemented with the prebiotic alone or in combination with Horse chestnut and flaxseed oil. The activity of faecal glycolytic enzymes, lipid parameters, bile acids, short chain fatty acids and counts of coliforms and lactobacilli were determined. Treatment with the prebiotic alone and in combination with selected substances significantly decreased the activity of glycolytic bacterial enzyme β-glucuronidase (P<0.001) and increased activities of β-galactosidase and β-glucosidase. Bile acids concentration was significantly decreased (P<0.01) except for the combination of the prebiotic with Horse chestnut. The prebiotic alone decreased the lipid parameters (P<0.001) and enhanced production of short chain fatty acids. Application of prebiotic and bioactive natural substances significantly reduced number of coliforms (P<0.05). Prebiotic alone significantly increased the count of lactobacilli (P<0.05). These results show that prebiotics have a protective effect and may be the useful for colon cancer prevention and treatment.

The ability of probiotic strain Lactobacillus plantarum LS/07 to modify the activity of intestinal bacterial enzymes - β-glucuronidase (β-GLUCUR), β-galactosidase (β-GAL), and β-glucosidase (β-GLU) in prevention of chronic diseases - cancer, atherosclerosis and dysbiosis was investigated. The male Sprague-Dawley rats were randomly divided into 12 experimental groups: controls groups - C (control), AT (atherosclerotic), CC (carcinogenic), dysbiotic groups - each group in combination with antibiotics (ATB), probiotics groups - in combinatioan with probiotic (PRO) alone, and each group with combination of antibiotic and probiotic (ATB+PRO). In the control group the β-glucuronidase activity did not change throughout the experiment. High fat diet in atherosclerotic group significantly increased the activity of β-glucuronidase (P<0.001) and β-glucosidase (P<0.01). Azoxymethane application in carcinogenic group significantly increased β-glucuronidase (P<0.01), but reduced β-glucosidase (P<0.01) activity. Daily application of probiotics alone and in combination with antibiotic increased β-galactosidase, of β-glucosidase, and decreased β-glucuronidase activity. In control antibiotic group we observed significant increase in β-glucuronidase (P<0.05) and decreased β-glucosidase (P<0.01) activity which can be caused by the change of microflora in favor of coliform bacteria. These findings indicate the positive effects of probiotic Lactobacillus plantarum LS/07 and suggest its use in disease prevention in human medicine and some animal species.
