The modern integrated approach to the treatment of ischemic stroke (IS), in addition to pharmacotherapy, provides for the impact of physical factors. Among them is injectable carboxytherapy (ICBT). Objective. The aim of the study was to evaluate the effi cacy and safety of using ICBT in combination with a standard treatment program in patients with acute ischemic stroke. Material and methods. The main group (MG) included 39 patients with acute IS, the comparison group (GC) — 31 patients. On the second day of hospitalization, patients with MG underwent ICBT on the background of standard therapy, and GC — procedures that mimic ICBT. Clinical, laboratory and instrumental data, IS outcomes, complications, timing were assessed.Results. There were no statistically signifi cant diff erences in physiological parameters (heart rate, blood pressure, SpO2) between MG and GC during and after the course of treatment. Positive dynamics of the neurological status was observed in both groups in the form of a decrease in the NIHSS score — in the MG from 6 to 4 (p = 0.047), in the GC — also from 6 to 4 (p = 0.25). In patients with MG, trophic disorders were less likely to develop in comparison with GC — 1 (2.6%) versus 6 (19.4%), p = 0.039. ICBT did not aff ect the duration of hospitalization of patients, the duration of treatment in the intensive care unit and carrying of resuscitation and also did not contribute to reducing mortality. Changes in the indicators of the acid-base state of the blood were compensatory in nature and did not lead to changes in the pH of the blood. The decrease in pH from 7.5 to 7.4 in 30–90 minutes after the procedures was a physiological reaction of the body to the introduction of CO2 and was not accompanied by negative consequences. Conclusions. ICBT is a safe method, does not aff ect the duration of hospital stay and mortality, help lower the likelihood of complications.

Introduction. Currently, the participation of women in space flights is increasing. In this regard, questions about the influence of space factors on the state of the female body arise inevitably. Model experiments, in particular, "dry" immersion, are most convenient for studying the influence of individual factors of space flight on the organism. The aim of this work is a comparative assessment of the state of the vaginal microbiota of 6 female volunteers before and after three-day "dry" immersion.Materials and methods. Microbial samples of all volunteers were stained according to Gram with a sequential culture study in accordance with the medical technology. The species identification of microorganisms was performed by MALDI-TOF-MS analysis using an Autoflex III time-of-flight mass spectrometer with Maldi BioTyper software.To assess changes in the state of the vaginal microflora and microflora of the cervical canal, eubiotic index was used. It reflects the number of positive states of microbiota to the number of negative ones.Results. After 3 days of "dry" immersion volunteers, who had high titer of aerobic microorganisms before isolation, had significant increase of the amount of aerobic microorganisms, while the number of lactobacilli decreased. The other group of volunteers showed activation of colonization resistance of the vaginal microflora. Volunteers, who had a significant contamination with anaerobic opportunistic microflora before isolation, had reduction of the number of all anaerobes, including lactobacilli. The eubiotic index, calculated for the cervical canal, decreased after 3 days of immersion. The data obtained indicate that after 3 days of isolation, the state of the microflora has deteriorated.
