    In the research, Si-HA poweders have been synthesized using SBF solution with different content of silicon. It was found that all the samples synthesized from the model solution of extracellular fluid under varying concentration of silicate ions are single-phase and repesent hydroxyapatite. The nature of the reagent containing SiO[44]- ions does not affect the hydroxyapatite structure. In the study of the surface and morphological characteristics of the phosphate coatings modified by silicon ions, it was found that as the degree of phosphate calcium substitution by SiO[44]- ions increases, the surface wettability on the titanium substrates deteriorates and cohesive energy decreases. It is shown that the titanium coating is formed in three stages. After irradiation of titanium substrates coated with Si-HA, the crystals can keep growing and the surface can keep regenerating

    Background. Prolong contact with manufacturing factors of gas producing, in particular hydrogen sulfide, results in dysfunction of various organs and systems, including immune system, which is involved in regulation of the aging process activity. Absence of effective geropreventive means creates the need for pathogenetic way for aging process deceleration. Aim. To study the geroprotective properties of rosuvastatin in respect of people engaged in the gas producing. Material and Methods. The male workers (n=100) of the company “Gazprom dobycha Astrakhan” were examined. Evaluation of biological age by the method of Chebotarev D.F ., determination of p53 protein and interleukin-8, 10, 18 concentrations by solid phase enzyme immunoassay were performed before treatment start and after 18 months of rosuvastatin taking. Results. Rosuvastatin therapy in dose of 5 mg/day resulted in the reduction in atherogenic lipids, pro-inflammatory cytokine - interleukin-8 and marker of apoptosis - protein p53 as well as aging rate slowdown. Conclusion. Pathogenic method of geroprevention with rosuvastatin 5 mg/day was proposed for people engaged in gas producing

    Background. Arterial hypertension during pregnancy is accompanied by pronounced changes in microcirculation and hemostasis in the system, the state of which is largely determined by the structural and functional properties of red blood cells and platelets. The study of quantitative and morphometric characteristics of blood cells will expand the existing understanding of their role in the pathogenesis of hypertensive disorders.Aim of the research. To study the quantitative and morphometric indicators of red blood cells and platelets in pregnant women with various forms of hypertensive disorders, on the basis of which to develop an additional method for the diagnosis of preeclampsia. Materials and methods. 237 women in the third trimester of pregnancy were examined. The main group (167 women) included patients with various forms of hypertensive disorders. The comparison group included 70 pregnant women without signs of hypertensive disorders. The characteristic of clinical and anamnestic data of the studied groups is given. A comparative analysis of the number and morphometric parameters of red blood cells and platelets was performed.Results. With moderate and severe preeclampsia, a decrease in the level of red blood cells, hemoglobin and hematocrit was not accompanied by changes in red blood cell indices. In women with preeclampsia, regardless of the presence of chronic arterial hypertension, an increase in the average dry weight, average volume and degree of platelet anisocytosis was detected. In severe preeclampsia and preeclampsia with underlying of  chronic arterial hypertension, an increase in the number of large forms of platelets and their granulocytosis was revealed, and in addition, in severe cases of preeclampsia, a decrease in platelet level was noted.Conclusions. Modern hematological analyzers make it possible to establish the nature of not only quantitative, but also morphometric changes in red blood cells and platelets, thereby complementing the existing understanding of the pathogenetic mechanisms underlying hypertensive disorders in pregnancy. Using average dry platelet mass and average blood pressure may be useful in diagnosing preeclampsia
