Osteoarthritis (OA) is a widespread pathology of the musculoskeletal system. OA may associate with a wide range of disorders, that lead to the development of various strategies on how to prevent and treat the disease. Recent studies discussed interactions between the microbiome and a wide range of pathologies, including OA. In this study, we investigated the effect of probiotic cultures on oxidative/antioxidant balance in blood of rats during OA. Experimental OA was induced by a single injection of sodium monoiodoacetate into the knee joint. A probiotic composition (Multiprobiotic Simbiter®) was administered by peroral catheter once per day for 14 days. We investigated the next parameters: expression of Nos2 gene in the blood, superoxide dismutase activity, catalase activity, glutathione peroxidase activity, glutathione transferase activity, glutathione reductase activity, contents of superoxide, hydrogen peroxide, TBA-reactive compounds, oxidized and reduced glutathione in the serum of the blood. Monoiodoacetate-induced OA caused significant changes on oxidative/antioxidant balance in the blood of rats: increasing of the contents of superoxide anion radical, hydrogen peroxide, thiobarbituric acid-reactive compounds, oxidized glutathione, upregulating of Nos2 expression, increasing of catalase activity; conversely, superoxide dismutase activity, glutathione peroxidize activity, glutathione transferase activity, glutathione reductase activity, the content of reduced glutathione were significantly decreased, compared to control group. Administration of probiotics to animals with OA led to positive changes in the studied parameters approaching the values of control group (some of them were statistically significant).
