To examine the effects of eprosartan on the remodelling of the heart and large vessels, on endothelial dysfunction and autonomic circulatory regulation in patients with hypertensive disease, thirteen patients were included into the study: Doppler echocardiographic study and evaluation of left ventricular diastolic function were performed on a Vingmed CFM800 apparatus: the thickness of the carotid intima-media complex and the diameter of the brachial artery were determined on the same apparatus using a 7.5-MHz transducer in the reactive hyperemia test. Automatic balance was evaluated by the spectral assay of cardiac rhythm variations. The cardiopulmonary component of baroreflex was also tested. Blood pressure normalized in 3 patients following 24 weeks of therapy with eprosartan in a daily dose of 600 mg. Two patients were excluded due to therapeutic inefficiency. In the remaining patients, the antihypertensive effect was incomplete. The mass of the left myocardial myocardium decreased by 10.8%. there was an increase in brachial arterial dilatation in the reactive hyperemia test. The variations of cardiac rhythm were not significantly changed, the baroreflex tended to be decreased. Thus, long-term eprosartan therapy improves the structural and functional state of the heart and vessels and fails to affect the autonomic regulation of circulation.

The article presents an analysis of autonomic regulation of heart rate against preventive procedures in university teachers. Aim. The paper aims to identify the features of autonomic regulation of heart rate in university teachers when using preventive measures. Materials and methods. The study involved 87 teachers aged from 25 to 60 years. The participants were divided into three subgroups depending on their professional experience. The functional status of the autonomic nervous system was assessed with the method of variational pulsometry using the UPFT-1/30 – Psychophysiologist. Dynamic electroneurostimulation through the DENAS-Vertebra-02 apparatus was used as preventive measures. Results. Under the effect of dynamic electroneurostimulation, distinct trends were formed to improve the functional status of the autonomic nervous system in teachers with the professional experience of 10–20 years. For specia­lists with the experience of 21–30 years and more a course of electric massage sessions was not enough or it could be combined with other means of relaxation. Conclusion. As preventive measures for teachers, dynamic electroneurostimulation can be used (DENAS-Vertebra-02), which obviously improves the functional state of the autonomic nervous system of teachers with professional experience of 10–20 years.

The Central Nervous System

The purpose of this research was to analyse the functional state of the central and autonomic nervous systems in young emergency physicians working in the northern region. Materials and methods. We examined 33 emergency physicians of a multidisciplinary hospital in Khanty-Mansi Autonomous Okrug – Yugra aged 25 to 43 years (19 men and 14 women). The functional state of the central nervous system (CNS) was assessed using the method of simple visual-motor reaction (SVMR) and criteria developed by T.D. Loskutova – system’s functional level (SFL), reaction stability (RS) and level of functional abilities (LFA) – as well as attention stability, working memory and Whipple’s accuracy index. The state of autonomic regulation was evaluated according to the dynamics of heart rate variability (HRV) at rest and during active orthostatic test (AOT). Results. We found that male emergency physicians have higher rates of psychomotor reactions, SFL, RS, and LFA than their female colleagues. SVMR showed pathological reactions of the CNS in subjects of both sexes. The body’s adaptive capabilities due to autonomic regulation were preserved in most emergency physicians. However, a pathological response to AOT was found in both men and women. The pathological basis for impaired autonomic regulation and the development of maladaptive reactions in the subjects was a deterioration of the current functional state of the body, excessive activation of the sympathoadrenal system and a decrease in parasympathetic regulation. Responses to AOT in male emergency physicians were accompanied by a decrease in the total power (TP) of the HRV spectrum by 24.7 %, and an increase in low frequency (LF) to high frequency (HF) ratio by a factor of 2.6; while in female doctors, by a decrease in TP by 11.5 % and an increase in LF/HF ratio by a factor of 1.7. The median of 30/15 coefficient was 1.48 for men and 1.45 for women. Thus, in the course of professional selection of doctors to provide emergency care under unfavourable climatic conditions of the North, it is advisable to conduct a comprehensive examination of the functional state of the central nervous system and autonomic regulation to identify a risk group with impaired adaptation mechanisms.

The dynamics of a functional state of cardiovascular and sympathetic adrenal systems in students aged 1719 years throughout the academic year in the first, second and third УДК 616.921.5-06-037 course of the Pedagogical Institute is studied. The adaptation process of students is shown to be accompanied by stress periods in the functional state of cardiovascular and sympathetic adrenal systems. The response of the systems under study to the dosed physical load varies according to their functioning intensity. The character of correlative relations between hormonal and mediative links of sympathetic adrenal system and statistical characteristics of the cardiac rhythm depends on the training period and may serve as a criterion of the functional stress of the students organism.

The article presents the results of assessment and dynamic control over the functional state of military men in the midlands conditions. Depending on the initial type of autonomic regulation, groups with vagotonic (24%), sympatotonic (26%) and normotonic (50%) directions of regulatory processes were identified. It has been established that the state of optimal working voltage with more economical functioning of regulatory mechanisms is characteristic of carriages; for sympathotonics - an overstrain of regulatory mechanisms, and for normotonics - a moderate tension of regulatory systems with the mobilization of the functional reserves of the body. Key words: heart rate variability, functional state, types of autonomic regulation, midlands, military men.

Cough Response

Abstract A neurogenic pathway, involving airway TRPV-1, has been implicated in acute cardiovascular events occurring after peaks of air pollution. We tested whether inhaled prostaglandin-E2 (PGE2) and bradykinin (BK) regulate TRPV-1 activity in vivo by changing cough response to capsaicin (CPS) and affecting heart rate variability (HRV), while also taking into account the influence of TRPV-1 polymorphisms (SNPs). Moreover, we assessed the molecular mechanism of TRPV-1 modulation in vitro. Seventeen healthy volunteers inhaled 100 μg PGE2, 200 μg BK or diluent in a randomized double-blind fashion. Subsequently, the response to CPS was assessed by cough challenge and the sympathetic activity by HRV, expressed by low (nLF) and high (nHF) normalized frequency components, as well as nLF/nHF ratio. Intracellular [Ca2+] was measured in HeLa cells, transfected with wild-type TRPV-1, pre-treated with increasing doses of PGE2, BK or diesel exhaust particulate (DEP), after CPS stimulation. Six functional TRPV-1 SNPs were characterized in DNA from each subject. Inhalation of PGE2 and BK was associated with significant increases in cough response induced by 30 μM of CPS (cough number after PGE2 = 4.20 ± 0.42; p < 0.001, and after BK = 3.64 ± 0.37; p < 0.01), compared to diluent (2.77 ± 0.29) and in sympathetic activity (nLF/nHF ratio after PGE2 = 6.1; p < 0.01, and after BK = 4.2; p < 0.05), compared to diluent (2.5–3.3). No influence of SNPs was observed on autonomic regulation and cough sensitivity. Unlike PGE2 and BK, DEP directly activated TRPV-1. Inhalation of PGE2 and BK sensitizes TRPV-1 and is associated with autonomic dysregulation of cardiac rhythm in healthy subjects.

Osteopathic Treatment

Introduction. Psychic retardation and its correction in children is an important problem in children’s psychoneurology. It is necessary to extend the variety of treatment methods, also by means of osteopathy. The analysis of the cardiac rhythm vaiability gives information about the functional state of the body and permits to follow its dynamics.Research objectives. Evoluate the influence of osteopathic treatment on the functional state of children presenting psychic retardation (according to the data of the spectral analysis of the cardiac rhythm variability). Research methods. An osteopathic evaluation and an analisys of the cardiac rhythm variability were held in a group of children presenting psychic retardation (31 boys aged from 5 to 7) before and after three osteopathic consultations. The statistical data processing was held with the use of the Wilcoxon test.Results. All the children presenting psychic retardation had somatic dysfunctions and tension of the body’s regulating systems (according to the evaluation of the data of the cardiac rhythm variability). After the course of osteopathic treatment on the background of correction of somatic dysfunctions all the children presenting psychic retardation showed decrease of the tension of the regulatory systems. The vegetative balance was achieved and the body’s adaptive capabilities improved.Conclusion. The results of the research permit to recommend the use of osteopathic techniques in combined therapy of children presenting psychic retardation, as well as the use of the analysis of the cardiac rhythm variability for evaluation of the effectiveness of osteopathic treatment.
