The aim of this work was to investigate the effect of the poly-strain probiotic on oxidative-antioxidant balance and the level of matrix metalloproteinases (MMPs) in rat knee cartilage under experimental osteoarthritis. Osteoarthritis was induced by a single injection of monoiodoacetate into the knee joint of rats. Probiotic was administered daily for 14 days. Knee cartilages homogenate was used to evaluate  the content of reactive oxygen species (superoxide anion and hydrogen peroxide), products of lipids peroxidation (diene conjugates, TBA-active compound, Shiff bases), to determine superoxide dismutase and catalase activity and activity of glutathione-dependent  antioxidant enzymes, the level of reduced and oxidized glutathione. The level of MMPs -1, -2, -3, -8 expression was estimated by ELISA. Osteoarthritis was found to cause a significant increase in the reactive oxygen species level, lipid peroxidation products content, superoxide dismutase and catalase activity, level of all studied MMPs, and also depletion of glutathione-dependent antioxidant system and the decrease in the ratio between reduced and oxidized glutathione.The administration of the probiotic was followed by the tendency for the restoration of the parameters to the values of the control group. Thus, the administration of the probiotic to rats with osteoarthritis may be considered as an anti-inflammatory and antioxidant agent for further clinical trials.

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).
