A comparative experimental analysis by EPR spectroscopy of the intensity of nitric oxide (NO) production and the content of the copper in the tissues of olfactory bulb of the brain of male Wistar rats were performed after modeling of ischemic stroke and treatment with immediate intranasal injection of mesenchymal stem cells (MSCs). Brain ischemia was simulated by ligation at the level of bifurcation of the common carotid arteries. It was found a significant reduction of NO content in the olfactory bulb of the brain of rats on the 1st and 2nd days after modeling of ischemia. The level of NO production was also reduced on the 1st and 2nd days after ischemia with MSCs' administration as compared to intact animals. It was not found the significant difference of the NO content in rats after ischemia with MSCs' administration relative to ischemic rats. The copper content in the olfactory bulb of the rat, which corresponds to the level of superoxide dismutase 1 and 3, tended to increase after modeling ischemia and remained for 2 days. The MSCs' administration was accompanied by a significant increase in copper content on the 1st day after modeling of ischemia and by decrease of its content on 2nd day after ischemia. The experiments showed that MSCs' administration did not affect the intensity of NO production on the 1st and 2nd days after the modeling of brain ischemia, but was accompanied by an increase in the antioxidant protection of the nervous tissue 1 day after ischemia.
