ASSESSMENT OF LEUKOCYTES FUNCTION IN PERIPHERAL BLOOD IN PATIENTS WITH MEDICINAL JAWS OSTEONEKROSIS.

The aim of the study was to assess the functional activity of peripheral blood phagocytes in patients with drug-induced osteonecrosis of the jaws to develop a new approach to treatment. A total of 35 people were examined, including: 10 healthy individuals, 8 with purulent-inflammatory diseases of the maxillofacial region (GVZ ChLO), 17 patients with medical osteonecrosis of the jaws (MRONJ). Among patients with MRONJ, there were 10 men and 7 women, aged from 54 to 73 years, with a mean age of 62 years.

[ALGORITHM FOR TREATMENT PATIENTS WITH MEDICAL OSTEONEKROSIS OF JAWS BY CORRECTING ORAL MICROBIOTAL DISORDERS].

The aim of the study was to develop a new approach to the treatment of patients with drug-induced osteonecrosis of the jaws based on the correction of disorders of the oral microbiota. We examined 22 patients with MRONJ and 10 healthy individuals aged 55 to 76 years. All patients underwent surgical treatment for cancer, in connection with tumor metastasis, they took bisphosphonates - the drug Zometa (zoledronic acid) in injections of 4 mg intravenously 1 time per month.

THE CONTENT OF NK CELLS AND THEIR SUBTYPES IN THE CASE OF DRUG-INDUCED JAW OSTEONECROSIS.

The goal of the study is assessing the population structure of lymphocytes and the subpopulation composition of NK cells in the peripheral blood of humans in the case of drug-induced osteonecrosis of the jaw for improving the quality of diagnosis, treatment, and prevention of osteonecrosis of the jaw. Thirty patients were examined, including 15 patients with drug-induced osteonecrosis of the jaw (ONJ), 10 healthy individuals, and five patients with pyoinflammatory diseases of the maxillofacial region, aged 49 to 77. Every four weeks, the patients had been receiving 4 mg intravenous injections of bisphosphonates (the Zometa preparation (zoledronic acid)) for 1.

[Diagnostic value of chromato-mass-spectrometry in patients with drug-induced jaws osteonecrosis].

In patients with drag-induced jaw osteonecrosis which developed in cancer patients due to administration of bisphosphonates for metastases, the microflora of the oral cavity was examined by chromatography-mass spectrometry (HMS). The method of HMS can be used as an additional method of diagnostics in complex clinical cases with ineffective treatment.

[The expression of TLR4 and HBD3 in epithelial cells of oral mucosa by surgical treatment of periodontitis].

The expression of TLR4 and HBD3 in epithelial cells of the oral cavity was studied using polymerase chain reaction in real-time in patients with inflammatory and destructive periodontal lesions before and after surgery using osteoplastic material. Analysis of TLR4 and HBD3 expression in epithelial cells demonstrates the key role of the innate immune factors in the pathogenesis of inflammatory and destructive periodontal lesions. TLR4 gene expression was increased 1.
