The effect of probiotics on ıntestinal motility in an experimental short bowel model

Abstract

To investigate the effect of probiotics on spontaneous contractions of smooth muscle isolated from jejunum and ileum of rat model. Methods: Four rat groups were created (n=8, in each) including control (Group 1), control+probiotic (Group 2), short bowel (Group 3), and short bowel+probiotic (Group 4). Groups 1 and 2 underwent sham operation, Groups 3 and 4 underwent massive bowel resection. Bifidobacterium Lactis was administered in Groups 2 and 4 daily (P.O.) for three weeks. On postoperative week 3, rats were sacrificed, and jejunum and ileum smooth muscle were isolated for organ bath. Muscle contraction changes were analyzed before and after addition of antagonists. Results: Short bowel group exhibited increased amplitude and frequency of spontaneous contractions. The addition of probiotics significantly decreased enhanced amplitude and frequency of bowel contraction in short bowel group and returned to control values. L-NNA increased amplitude and frequency of contractions in all groups. While indomethacin and nimesulide increased the amplitude in all groups, the frequency was only increased in jejunum. Hexamethonium and tetrodotoxin did not change the contraction characteristics in all groups. Conclusion: We suggest that early use of probiotics may significantly regulate bowel motility, and accordingly improve absorption of nutrients in short bowel syndrome.

“…Additional potential innate immune adaptation, for example, M1 to M2 conversion, has not been well studied. Understanding the fundamental biological processes governing the phenomenon of immune tolerance in SBS patients, including the interplay between the host and microbiome, would lead to a better understanding of the mechanisms underlying lack of SBS patient reactivity to GN sepsis, and could provide insight into the development of novel therapies against sepsis and septic shock, some of which may include either targeted therapeutic approaches by immunomodulation, alterations of the microbiome with probiotics, or a combination of both [ 43 , 44 , 45 , 46 ].…”
