ABSTRACT
Tibetan mushroom (TM) is a fermented beverage composed by a dozen of bacteria and yeasts living together into polysaccharide grains secreted by them. TM is similar to kefir, a probiotic beverage originated in the Caucasian mountains exhibiting some anti-bacterial, anti-mycotic, anti-neoplastic and immunomodulatory effects. Aiming to evaluate a plausible anti-inflammatory property of TM we conducted cotton-induced granuloma and paw edema assays in rats, the latter using carrageenin, dextran and histamine as stimuli. TM samples were thawed and continuously cultured during 15 days into molasses solutions (50 g/l). The experiments used TM suspensions after 24h fermentation and TM grains mechanically disintegrated. The results showed a significant inhibition on the formation of granuloma tissue for the test group as compared to the negative control group. TM suspensions presented an inhibition of 43% for the inflammatory process. Rat paw edema also showed significant decreases with the mediators. The edema induced by carrageenin was inhibited 62% at the 3rd hour. The edema dextran-induced was completely inhibited at 1h and antagonized the histamine edema 52% at 1h.

O quefir é uma bebida fermentada originária do Cáucaso e formada por bactérias ácido-lácticas e leveduras, sendo utilizada por suas propriedades organolépticas e terapêuticas. O presente estudo avaliou a atividade antiinflamatória deste probiótico sobre modelo de indução de tecido granulomatoso e contorções abdominais induzidas por ácido acético, in vivo. Os resultados obtidos mostraram que o quefir inibiu a formação do tecido granulomatoso, bem como o número de contorções abdominais causadas por ácido acético, quando comparado ao grupo controle. Desta forma, pode-se sugerir uma possível ação antiinflamatória.
Kefir is a fermented beverage with its origin in Caucasian region, formed by acid-lactic bacteria's and yeasts, and used due to its organoleptic and therapeutic properties. The present study evaluated the possibility of an anti-inflammatory activity for induction of granulomatous tissue in rats and writhing test in mice. The results obtained shown that the kefir has inhibited the formation of the granulomatous tissue, as well as the number of writhings induced by acetic acid as compared to a control group. In this way the authors suggest a possible antiinflammatory action.
