The Tibetan mushroom (CT) is a probiotic beverage fermented by a big group of bacteria and yeasts, some of which of well-known anti-bacterial activity, immunomodulatory, pro-digestive and to aid of the intestinal peristalsis. In this sense, this work had the aim of evaluating the possible action of the suspension produced by CT on the peristalsis intestinal of rats. Animal groups weighing 200 ± 20 g were used (Wistar rats (male, n = 6/group)). The different groups were treated v.o. for 15 days (1,5 mL/animal of 24h fermented of CT in continuously cultured into molasses solutions (50 g/l)), and the other groups treated with distilled water (1,5 mL/animal). After 15 days the animals were maintained in fast for 24h, and treated with suspension CT (1,5 mL/animal/v.o), distilled water (control, 1,5mL/animal/v.o), acetylcholine (1mg/kg/s.c) and atropine (1mg/kg/i.m). After 30 min, the animals received a suspension of active coal 10% (0,1 mL/10g, v.o), after the euthanasia, excision of the portion of the pylorus to the beginning of the cecum, and determination of the distance traveled by the coal. The administration of the CT suspension increased the intestinal peristalsis in 68,7% and the other treatments presented the following percentages: atropine 20,2%, acetylcholine 78,7% and control 42,9% (p < 0,05, ANOVA followed by Tukey-Kramer test). Those results showed that the CT suspension stimulated the peristalsis in the animals, what suggests a positive effect in the digestion and alimentary absorption for the microbial consortium.
