Effects of Saccharomyces cerevisiae or boulardii yeasts on acute stress induced intestinal dysmotility

Figure 5 Saccharomyces cerevisiae helped to reduce dysmotility in the stressed gut, with most visible effects on the jejunum. A and C: Saccharomyces cerevisiae (S. cerevisiae) increased stressed jejunal propagating contractile clusters velocity and decreased velocity in the stressed colon. S. cerevisiae increased jejunal frequency and slightly decreased peak amplitude in both the colon and jejunum. 95%CIs straddled 0 for mean paired differences in colonic frequency; B and D: Dmaps representing the stressed gut before and after addition of S. cerevisiae. S. cerevisiae helped to restore jejunal motility after stress. S. cerevisiae had less potent effects on the stressed colon, but helped to ease some of the dysmotility.
