RESUMEN
We studied the dynamics of the main hemodynamic parameters in spontaneously hypertensive rats (SHR) and Wistar-Kyoto (WKY) rats with visceral obesity and chemically induced colitis (CIC) against the background of probiotic therapy. Systolic BP, HR, and body temperature were recorded over 36 days using a wireless telemetry system. During 8 days (3 days before CIC induction and until the end of the experiment) the animals were intragastrically administered a probiotic based on Lactobacillus delbrueckii D5 strain. At baseline, systolic BP was significantly higher in the SHR group, while HR and body temperature did not differ in SHR and WKY rats. On day 8 after CIC induction, systolic BP, HR, and body temperature in SHR were significantly increased in comparison with the initial values. In the group of WKY rats, all indices at the end of the experiment remained at the initial levels. Probiotic therapy in SHR, in contrast to WKY rats, did not lead to normalization of body temperature and hemodynamic disorders resulting from CIC.

The effect of probiotic therapy on the main hemodynamic parameters was studied in Wistar rats with modeled syndrome of systemic inflammatory response resulting from chemically induced colitis complicated by antibiotic-induced dysbiosis. Using a wireless telemetry monitoring system in round-the-clock mode, the mean systolic and diastolic BP, HR, and body temperature were measured over 27 days. In the group of animals receiving no probiotics, a significant decrease in feed consumption and body weight loss were observed. By the end of the experiment, BP in this group was lower by 12% and HR was higher by 10% than in the control. In animals treated with a mixture of probiotic strains Lactobacillus acidophilus and Bifidobacterium animalis subsp. lactis, all the studied parameters returned to the initial values. Thus, we demonstrated the possibility of using probiotic drugs for the treatment of acute systemic inflammatory process, which should be considered in the development of new treatment protocols in veterinary and medicine.
