Effects of probiotic bacteria on gastrointestinal motility in guinea-pig isolated tissue

Figure 6 Relaxation induced by B. infantis cytoplasmatic fraction, cytoplasmatic proteinaceous components, cytoplasmatic non-proteinaceous components and cytoplasmatic fraction proteinase K digested on guinea-pig proximal colon Relaxation was expressed as change in mg-tension per cm of chart paper in resting tone (A). Relaxation was expressed in percentage, by considering cytoplasmatic fraction-induced maximal relaxation as 100% (B). The volume (μL) indicates the minimal value exerting maximal relaxation effects. Each crude extract was prepared from a bacterial suspension equivalent to a concentration of 3.5 x 10⁹ CFUs/mL. Each point is the mean ± SE of 5 to 7 observations.
