BACKGROUND: Cardiovascular (CV) diseases are the most spread cause of mortality in the world. Essential arterial hypertension (EAH), as a major risk factor for the development of CV diseases, is a multifactorial disease involving environmental and genetic factors together with risk-conferring behaviors. AIM: The purpose of this study was to analyze lipid metabolism changes in patients with EAH depending on the Vitamin D receptor (VDR rs2228570 (aka rs10735810)) and angiotensinogen (AGT rs699) genes polymorphism. MATERIALS AND METHODS: The single-stage study involved 100 patients suffering from Stage 2 EAH, 1–3 degrees of blood pressure increase, high and very high CV risks, 21% (21) men, and 79% (79) women. The average age of patients was 59.86 ± 6.22 years old. The control group included 60 practically healthy individuals of an appropriate age and sex distribution. To examine the VDR gene (rs10735810, rs2228570) and AGT gene (rs699) polymorphism, a qualitative real-time polymerase chain reaction was made. The lipid metabolism was studied by determining the blood plasma content of total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and triglycerides (TGs). RESULTS: Т allele of AGT gene is associated with reduced HDL-C level in men and increased TGs level in women. The EAH risk increases 4.5 times as much among the ТС-genotype carriers and lowered HDL-C level (odds ratio [OR] = 6.43; p = 0.01). The EAH risk increases as far as the HDL-C level reduction, irrespective of the VDR gene alleles condition 1.83 times (OR = 2.37; OR 95% confidence interval [CI]: 1.02–5.51; p = 0.04) and 1.9 times (OR=2.43; OR 95% CI: 0.99–5.97; p = 0.04). HDL-C reduction and LDL-C elevation in women increase the EAH risk 2.4 times (OR = 3.27; p = 0.01) and 1.24 times (OR = 3.67; p = 0.01), respectively. CONCLUSIONS: The EAH risk increases with a reduced HDL-C level in the TC genotype carriers of the AGT gene and irrespective of VDR gene polymorphic variants.
The aim of the study was to study the effect of low and high doses of lead acetate on biochemical parameters and morphological status of rat ovaries in the experiment. Materials and methods: The study was performed on 36 nonlinear female rats weighing 180-210 g, aged 4 months, divided into 3 experimental groups: I - control (C), II - rats, which were given 30 days to drink a solution of lead acetate with at the rate of 0,05 mg / kg of animal weight, group III - rats, which were given for 30 days to drink a solution of lead acetate at the rate of 60 mg/kg of animal weight. Biochemical research methods were included determination of diene conjugate concentration in animals’ blood, concentration of TBA-active products, study of oxidative modification of proteins in blood plasma, determination of superoxide dismutase and catalase activities. Endogenous intoxication was assessed by the definition of medium-mass molecules, the content was expressed in units of extinction. The material for light microscopy investigation from the ovary was performed according to the generally accepted method. Results: Lead acetate causes activation of peroxidation of lipids and proteins in the body of female rats, which is directly dependent on the dose of lead. In response to the activation of free radical oxidation there are changes in the antioxidant system, which depend on the dose of lead acetate: at a dose of 0.05 mg / kg superoxide dismutase and catalase activity increase, at a dose of 60 mg / kg superoxide dismutase and catalase activity. Small doses of lead do not cause endogenous intoxication. Lead acetate causes the development of endogenous intoxication in animals only in large doses: increases the formation of toxic compounds, cell apoptosis, decreased excretory function of the kidneys, which is associated with multiorgan disorders. As a result of the action of lead acetate, morphological changes of the ovaries were observed, which increased with increasing dose of lead acetate. There was a dose-dependent decrease in massometric parameters, the number of follicles and changes in the thickness of the surface structures of the ovary, which is more pronounced at 60 mg/kg. Conclusions: Under the influence of small and large doses of lead acetate on biochemical changes in blood and morphological changes in the ovaries in male rats the oxidative stress is developed. Under the influence of small doses, the changes are adaptive, and under the influence of large doses - damaging.
The aim of the research is to analyze the problem of inclusive education in Ukraine in the context of world trends. According to its philosophy, each school should be inclusive, which implies the readiness of the school to accept every child with SEN at any time, the desire to create the most favorable educational environment that will serve the development of its potential. According to the results of the analysis, we also conclude that Ukrainian scientists pay more attention to issues of inclusion related to higher education (foreign experience, features of teaching students with inclusion, training future teachers to work with children with disabilities, etc.). Meanwhile, in our opinion, the theoretical and methodological principles, pedagogical conditions, practical methods of organizing inclusive education of children with various types of developmental disabilities are insufficiently studied. This, among other things, highlights the scientific problem raised in our study. Thus, the attention of the Ukrainian state to people with SEN, European-oriented social educational policy is evidenced not only by the reduction of the number of boarding schools, orphans and children deprived of parental care there, but also the dynamics of growing enrollment of children with SEN in inclusive special classes of secondary schools (in 2020/2021 academic year compared to 2015/2016 academic year this amount increased by 7% (from 5.3 thousand to 5.7 thousand). As a result of the development of inclusive education over the past five years, the number of students with SEN covered by inclusive education has increased more than 6 times, and the number of inclusive classes in secondary schools has increased 7 times. Similar changes have taken place in the staffing of inclusive education. Inclusive education and upbringing of children with SEN is a long-term strategy that is considered not as a local area of work, but as a systematic approach to organizing the activities of the general education system in all areas in general.
The aim: To investigate the nature of morphofunctional changes in the parenchyma and bloodstream of the testes of white rats with prolonged administration of high doses of prednisolone. Material and methods: The experiments were performed on rats fed daily for 1, 3, 7, 14 and 28 days. prednisolone was administered intramuscularly at a rate of 0.4 mg / kg. Massometric, organometric, histological and morphometric studies were performed. Results: Administration of high doses of prednisolone resulted in a significant increase in body weight and testicular weight and volume. As the drug was administered, spermatogenesis was activated. The number of immature forms of germ cells increased significantly. At the same time, the specific number of mature forms of sperm decreased. This led to a significant increase in the diameter of the convoluted tubules, the thickness of the spermatogenic epithelium, as well as the index of spermatogenesis. The increase in indicators was especially intense until the 7th day of observation, after which its rate decreased, although the dynamics remained unchanged. The thickness of the protein shell tended to decrease. The detected changes occurred against the background of dilation and plethora of arteries, especially up to 7-14 days of the experiment, after which their intensity decreased slightly. This was accompanied by a simultaneous reversible narrowing of the lumen of small arteries and arterioles. Conclusion: Thus, long-term administration of high doses of prednisolone promotes the activation of spermatogenesis with an increase in immature forms of germ cells and a simultaneous decrease in the proportion of mature sperm. Increased vascular blood supply, especially in the early period. In the long run, the capacity of small arteries and arterioles is reduced, as well as the degree of activation of spermatogenesis.
The aim: To clarify the efficacy of probiotics use as a preventive measure for post-antibiotic treatment in acute peritonitis and increase staff awareness related to antibiotic and probiotic use. Materials and methods: The study design included determination of the proper antibiotic and probiotic strain combination and clinical application of probiotic strains. The control group consisted of 63 (48.46%) patients who underwent traditional multimodal treatment of peritonitis and the study group of 67 (51.54%) individuals, with inclusion of different antibiotic/probiotic combinations. Results: Prior to antimicrobial therapy 67.7% patients of both groups’ patients had severe dysbiosis, proving dysbiosis as a sign of peritonitis. S. boulardii showed widest resistance spectrum and was used for probiotic therapy in study group. Intestinal dysbiosis grades distribution in control group significantly worsened, while in study group ratio of severe dysbiosis significantly dropped from 58.2% to 38.8% with significant growth of grade II dysbiosis to 61.2%. No visible differences in disease course and clinical picture, duration or complications rate between study and control groups were observed. Conclusions: Most of probiotic strains lack antibacterial resistance that makes meaningless their use during systemic antibiotic therapy of acute peritonitis. It is characterized by harsh changes of intestinal microbiota (severe intestinal dysbiosis). While probiotic strains showed antibiotic tolerance, their use presented no significant clinical efficacy, though high level of positive influence on intestinal dysbiosis was observed.
