Popis: Importance. Determining the influence of different medications in the development of different diseases is a prerequisite for adequate comprehensive treatment of patients. At present, there is insufficient data on the influence of anti-osteoclastic drugs on the microcirculation, which may have an impact. The aim. To study the effects of the monoclonal antibody denosumab on the development of osteonecrosis of the jaw of rats. Methodology. The study was carried out on 36 Wistar Line rats in the Department of Pathophysiology with the course of clinical pathophysiology First Pavlov State Medical University. The osteonecrorosis of the jaws of rats was induced by the extracted of a lower first molar. The observation was carried out with diagnostic studies of microcirculation (doppler), bone structure (3D computer tomography of jaws), followed by statistical processing of the data. Results. It has been shown that the greatest decrease in blood flow rate and the greatest bone defect is determined in the group of rats with the maximum dose of the monoclonal antibody preparation of denosumab by the time of 4 weeks, 0.5 mg/kg intravenous administration. Also, there has been evidence of a difference in blood flow reduction between the histological layers of the lower jaw. Thus, the intrabone blood flow was damaged much more, than the layer of mucous membrane of the gum. Conclusions. The combined method of dopplerography allows the determination of blood flow status on different histological layers. It is possible to determine the extent to which different pharmacological preparations influence the rate of blood flow in the local area without invasive interventions. The study of monoclonal antibodies is an acute problem in the world of surgical dental practice, which requires further study.
