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

Figure 3 Relaxation induced by crude extract of VSL#3 mixture, Lactobacillus, Streptococcus, Bifidobacterium, Escherichia coli, Salmonella aboni and Bacillus licheniformis preparations 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 VSL#3 mixture-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. Mean ± SE was given (P < 0.05).
