At 35.6 ± 1.12 weeks of gestation there was performed the preinduction of labor with premature rupture of membranes (PROM) in 50 women. It was performed using an analogue of prostaglandin E2. Preinduction of labor efficiency for initiation of delivery in the absence of significant deterioration in perinatal outcomes was achieved in 84 % of cases. There were identified objective ways to evaluate the dynamics of the transformation of the cervix by ultrasound monitoring, depending on the method of preinduction of labor in women with preterm pregnancy and PROM. There was performed the analysis of features of utero-fetus-placental hemodynamics, uterine activity during preinduction of labor in women with PROM at 34–36 weeks gestation.

The aim of the study was the evaluation of prostaglandin E2 (PGE2) influence on cholinergic cardiac innervation. Our experimental investigation established that PGE2 induced cardiodepressor effect in normotensive cats (n = 88) due to vagus nerves activation. PGE2 stimulated vagal C-afferent fibers thus leading to vagotonia. Vagotonic effect of PGE2 is one of the mechanisms for myocardium contractility and antihypertensive action. PGE2 modulating cholinergic influence may improve blood pressure control and morphology and function of vital organs.

In the study the ability of dihydroquercetin to inhibit the development of free radical reactions in the process of storing a new animal extracted product «Splenaktiv» (SA), which is a freeze-dried aqueous extract of the cattle spleen, was investigated. SA was prepared without (SA-1) and with dihydroquercetin supplement as an antioxidant (SA-2). The antioxidant activity of SA-1 and SA-2 and the content of lipid peroxidation product — malondialdehyde — were determined before and after storage for 2 years. It was found that after the period of storage of the selected antioxidant activity of the animal extracted product SA-1 decreased by10 times, and the content of malondialdehyde increased by 2 times as compared to baseline (p <0.01), whereas in the case of SA-2 the appropriate parameters practically did not change. Thus, the use of dihydroquercetin as an antioxidant in the composition of SA inhibits the development of oxidation processes and increases its shelf-life.

Depending on the insertion-deletion polymorphism of the angiotensin-converting enzyme and Hindlll DNA polymorphism of lipoprotein lipase gene there were studied the clinical course of coronary heart disease and five-year survival of patients after an exacerbation of the disease. It was found that the most important genetic predictors of short- and long-term adverse outcomes of acute ischemic heart disease are the genotype H+H+ of lipoprotein lipase gene, DD genotype of the angiotensin-converting enzyme gene and the combination of these genotypes.

A complex clinical-hygienic study in employees of a petrochemical complex for the production of synthetic resins was conducted. The main hazardous factor in the working environment under the study was a chemical production factor which was represented by 2–3 class hazards. In general, the working conditions were closely matched to class 3.3 according to the level of a chemical factor. The priority classes of chronic non-infectious diseases among petrochemical workers revealed statistical evidence for association of the disease with the work, characterizing the professional risk to the health of the workers.

We have assessed occupational risks among oil extraction workers using hygienic and medico-biological criteria. In modern oil extraction enterprises, a complex of work environment and work process factors includes occupational noise, vibration, hazardous chemicals impact, outdoor air negative indicators, work severity and intensity. Working conditions in certain occupations are characterized by a combination of predominating factors. Their intensity is of class 3 (1-4 degree) hazards. The presence of hazardous factors leads to the development of occupational and work-related diseases among workers. The highest health occupational risk level is detected in drillers, assistant drillers, operators of major, underground drill hole repairs, and machine operators. Optimization measures for occupational risk management have been developed.

Basic principles of liquid chromatography-tandem mass spectrometry method (LC-MS/MS) and its role in drug discovery and preclinical studies are reviewed. Three stages and components of the method in modern bioanalysis application are considered — sample preparation, liquid chromatography and mass spectrometry. The method trends and features for early drug screening and subsequent preclinical study of pharmacokinetics of drugs are discussed.

The influence of natural polyphenolic compounds included in a new collection of medicinal plant products on the physical endurance of mice in the re-swim test was studied. It was found out that the course application of aqueous extract from the plant collection in the experimental group of mice did not effect the duration of the primary swim, but increased to 1,7 times the length of re-swimming against the same parameter in the control group (p <0.001). This result demonstrates the positive effect of the proposed plant collection on the recover processes after physical activity, i.e. its actoprotective action. It is assumed that the actoprotective action of the medicinal plant collection is due to antioxidant properties of biologically active substances in its composition.
