CLINICAL AND FUNCTIONAL STATE OF THE THYROID GLAND IN WOMEN OF PERI- AND POSTMENOPAUSAL AGE WITH METABOLIC SYNDROME

The article deals with the problem of the clinical and functional relationship between the state of the thyroid gland in women of menopausal age and the components of the metabolic syndrome (MS). The purpose of the study: to assess the relationship between thyroid dysfunction and various components of MS in women of peri- and postmenopausal age. 80 menopausal women (mean age 55 years) were examined, of which 40 people with MS constituted the main group, and the comparison group - a similar number of women without MS. The inclusion criterion in the study was the presence of signs of abdominal obesity (AO) according to the WHO criteria (2008). Anthropometric, functional (BP), laboratory (lipidogram, TSH, freeT4, antibodies to TPO, FSH, LH, urinary iodine concentration) and instrumental (ultrasound of the thyroid gland) data, statistical analysis using the program SPSSStatistics version 20 were evaluated. The women were divided into two age groups: group 1 - perimenopausal and group 2 - postmenopausal. There were 40 people in each group (20 women with MS and 20 women without MS). It has been shown that peri- and postmenopausal women with MS have subclinical hypothyroidism. The influence of peripheral blood TSH levels in peri- and postmenopausal women with MS on body weight, carbohydrate and lipid metabolism, and sex hormones was established.

Synthesis, crystal molecular structure, and magnetic characteristics of coordination polymers formed by Co(ii) diketonates with pentaheterocyclic triphenodioxazines

Heteropentacyclic triphenodioxazines are shown to be efficient bridging ligands in the synthesis of 1D coordination polymers, whose structure and stability depend on the electron accepting properties of the substituents in the diketonate moieties.

[INDICATORS OF CARDIOHEMODYNAMICS OF RHYTHM DISTURBANCES IN ELDERLY PEOPLE WITH CHRONIC HEART FAILURE]

The aim of our study was to study and analyze the electrophysiological indicators of rhythm disturbances in heart failure in elderly people who participated in the elimination of the consequences of the Chernobyl accident in the distant period. In order to assess the functional features, 50 elderly patients (65-74 years old) who participated in the liquidation of the consequences of the Chernobyl accident were examined. Patients were divided into 4 groups depending on the length of stay in an environmentally disadvantaged zone: group 1 (April-June 1986) - 8 (16%) people; 2 (June-December 1986) -14 (28%); 3 (1987-1989) -17 (34%) and group 4 (1990-91gg) -11 (22%) people. All patients were on basic therapy. To study cardiogemodynamics in this category of patients, the following electrophysiological research methods were performed: ECG, XM ECG, SMAD, EchoCG. When analyzing electrophysiological studies, the MSExcel and Statistica programs were used. The examined patients showed a high incidence of left ventricular hypertrophy and cardiac arrhythmias. So in the 1st and 2nd groups, atrial fibrillation, sinus tachy and bradycardia, AV blockade of 1-2 degrees were reliably detected. In groups 3 and 4, left ventricular hypertrophy and arrhythmias were detected with a lower frequency. It should be noted that these changes were observed in individuals participating in the LPA from April to December 1986, i.e. in the first year after the accident. According to echocardiography, diastolic dysfunction of the left ventricle was found mainly in individuals of 1-2 groups. High high indices of KDR, BWW and KSO in 1-2 groups are noted. LVMI exceeds its norm in all studied groups. Thus, statistically significant differences of some indicators are revealed with electrophysiological research methods in all groups of elderly patients with heart failure participating in the liquidation of the Chernobyl accident, as well as the high incidence of rhythm disturbances in patients with Chernobyl nuclear power plants.

[ARTERIAL HYPERTENSION AMONG WORKERS OF A URANIUM PROCESSING ENTERPRISE OF THE REPUBLIC OF KAZAKHSTAN: PREVALENCE, RELATIVE RISKS AND PREDICTORS OF THE DEVELOPMENT]

The aim of this study was to establish the prevalence, relative risks, and predictive factors of the development of arterial hypertension (AH) in workers of a uranium processing enterprise (UPE). An open cross-sectional comparative study of 809 UPE workers was conducted. The compared them to the 696 workers of the bearing plant, located at a distance of 10 km from UPE. Stratification was performed and odds ratios (OR), gross (RR) and standardized relative (SRR) risks of hypertension were calculated. Our results revealed a high prevalence of hypertension among UPE workers (24.8%), as well as greater risk of development of hypertension among workers of UPE in comparison to the personnel of the non-uranium enterprise: RR=2.4 and SRR=2.9. The most significant predictors of hypertension were burdened heredity (OR = 13.6), total radiation dose (OR=1.5), overweight (OR=1.1), high anxiety (OR=0.5) and systematic use of alcohol (OR=0.5). Thus, among workers chronically exposed to radiation toxicity, high prevalence of hypertension, excessive RR and SRR of developing hypertension and the presence of risk factors for hypertension were established.

Ebola virus infection in guinea pigs: presumable role of granulomatous inflammation in pathogenesis

An approach combining virology with light and electron microscopy was used to study the organs of guinea pigs during nine serial passages of Ebola virus, strain Zaire. It was observed that the wild type of Ebola virus causes severe granulomatous inflammation in the liver and reproduces in the cells of the mononuclear phagocyte system (MPS). Based on morphological characterization, two types of virus-cell interactions were demonstrated. The obtained data evidenced for heterogeneity of the population of wild type of Ebola virus. The virus accumulated in the liver of the infected animals, and the lesions became more pronounced with passage. Degenerative changes appeared, and their severity was increased with passage in the other organs as well. The set of target cells diversified and, as a result, not only the MPS cells, but also hepatocytes, spongiocytes, endotheliocytes and fibroblasts became involved in the reproduction of Ebola virus. The possible role of granulomatous inflammation in the development of the adaptive mechanism of Ebola virus to guinea pigs is discussed.
