Effect of xyloglucan associations with gelatin or gelose on Escherichia coli-derived lipopolysaccharide-induced enteritis in rats
Background: Escherichia coli is the predominant non-pathogenic facultative microbe of the human intestine, although some strains are diarrhoeagenic in humans. E. coli-derived lipopolysaccharide (LPS) induces diarrhoea, intestinal barrier impairment, bacterial translocation and intestinal inflammatio...

| description | Background: Escherichia coli is the predominant non-pathogenic facultative microbe of the human intestine, although some strains are diarrhoeagenic in humans. E. coli-derived lipopolysaccharide (LPS) induces diarrhoea, intestinal barrier impairment, bacterial translocation and intestinal inflammation. Associations with the mucoprotectant xyloglucan exhibit antidiarrhoeal effects. This study evaluated and compared the effects of xyloglucan in combination with gelatin or gelose (agar-agar) on jejunal permeability and inflammation using an in vivo rat model of E. coli LPS-induced enteritis.
Methods: Xyloglucan (12.5 mg/kg) plus gelatin (250 mg/kg) or gelose (250 or 500 mg/kg) were administered orally 2 hours before intraperitoneal injection with E. coli LPS. Following euthanasia, jejunal segments were removed for intestinal permeability measurement in Ussing chambers and inflammatory tone evaluation by myeloperoxidase activity assay.
Results: LPS administration increased jejunal permeability and increased mucosal inflammation in male Wistar rats. Xyloglucan plus gelatin 250 mg/kg and xyloglucan plus gelose 500 mg/kg significantly attenuated LPS-induced jejunal hyperpermeability and myeloperoxidase activity.
Conclusion: Xyloglucan, a known mucosal barrier protector, in combination with gelatin or gelose, has beneficial and comparable effects on intestinal permeability and inflammation following E. coli LPS insult in male rats. |
