Comparative Study of the Efficacy of Prebiotics and Probiotics as Dietary Supplements in Rats with Gastric Ulcer

Gastric ulcer is considered as main problem of gastrointestinal disease, presenting one of the most important health issues in all societies. This comparative study designed to explore the anti-ulcerogenic role of probiotics and prebiotics and to evaluate the most potent effect against gastric ulcer. Sixty rats were distributed into 6 groups : G1 Healthy control; G2 gastric ulcer (GU), ulcer was induced by four oral doses of Aspirin 200 mg/kg b.w./week ;G3 Prebiotics (PreB) administered orally group ( 0.5 g/day); G4 Probiotics (ProB) administered orally group ( 0.5 mg/day); G5 Prebiotics (Therapeutic): prebiotics was administered orally at dose ( 0.5g/day) for 30 days after induction of gastric ulcer (GU+PreB); G6 Probiotics (Therapeutic): probiotics was administered orally at dose ( 0.5mg/day) for 30 days after induction of gastric ulcer (GU+ProB). Oxidative stress parameters and inflammatory markers were measured. Results revealed that: aspirin caused gastric ulcer associated with increased MDA, TNF-α, IL-6, and IL-10 and decreased gastroprotective mediators SOD, GSH, CAT, and PGE2compared with control rats. Treatment with prebiotics or probiotics efficiently reduces gastric injury, oxidative stress and proinflammatory cytokines. Comparing treatment groups showed that, Probiotics as a therapeutic group was the most potent demonstrated a hopeful role against gastric ulcer.
