Aim: to study the bioelectric activity of the brain in relation to changes in the tone of the autonomic nervous system as assessed by heart rate variability (HRV) and evoked skin  sympathetic potentials (ESSP) in patients with migraine and epilepsy.Materials and methods. We studied patients with epileptic foci in the left (group 1) or right (group 2) hemisphere with migraine attacks followed by epileptic seizures. We used EEG recording  and EEG mapping programs and also determined HRV and ESSP.Results. We found that the subjects in group 1 had the normothymic and parasympathetic types  of heart rate control, and the subjects in group 2 tended toward the sympathetic type of heart rate  regulation. The spectral correlation EEG data indicated that the epileptiform activity in group  1 was more generalized than in group 2, which pointed to a more pronounced epileptogenesis in  group 1. In this group, all pain scores were higher than those in group 2. In group 2 though, depression, anxiety, and emotional disorders were more pronounced than in group 1.Conclusion. The findings can be explained by a closer connection between the right hemisphere and the limbic system. This, in our view, underlies the more pronounced changes in the tone of the  autonomic nervous system as assessed by the HRV and ESSP in patients with the right hemisphere epileptic activity and migraine attacks.

This study was designed to investigate the possible role of angiotensin and vasopressin in the maintenance of arterial blood pressure during acute blockade of the autonomic nervous system. Two groups of eight dogs each were anesthetized with pentobarbital sodium, and autonomic ganglia were blocked with hexamethonium (20 mg/kg). Thirty minutes later group 1 received the vasopressin antagonist 1-(beta-mercapto-beta, beta-cyclopentamethylene propionic acid),2-(O-methyl)tyrosine arginine vasopressin (10 micrograms/kg) followed after a 30-min interval by captopril (1 mg/kg). Group 2 received the same drugs, except the order of administration of vasopressin antagonist and captopril was reversed. Vasopressin antagonist during ganglionic blockade (group 2) produced a greater fall in blood pressure than did captopril during ganglionic blockade (group 1). These data indicate that vasopressin plays a greater pressor role than angiotensin in the acute response to ganglionic blockade. Additional studies were performed to determine if the autonomic nervous system alone can support the resting blood pressure in the anesthetized dog. Combined blockade of angiotensin and vasopressin without autonomic blockade produced a significant decrease in blood pressure, suggesting that the autonomic nervous system alone is not able to support the control blood pressure in the anesthetized dog.

The objective: to establish the features of fetus functional state definition in pregnant women with perinatal losses in history. Patients and methods. 89 pregnant women with perinatal losses in history were screened. The fetus functional status evaluation was based on cardiotocography and definition of fetal heart rate variability by cardiointervalography. Results. Received data showed the decrease of SDNN, RMSSD and pNN50 in pregnant women with perinatal losses in history, indicating the prevalence of parasympathetic effects on the fetal myocardium (p<0.05). Studies of mathematical time characteristics of fetal heart rate revealed a significant overweight of the metabolic-humoral regulatory circuit in women with normal pregnancy (p<0.05). Dynamic stress index evaluation indicates the centralization of heart rate regulation and significant intensity of the fetal compensatory mechanisms in pregnant women with perinatal losses in history. The cardiotocography revealed no difference between the fetal status in women of comparative groups (p>0.05). Conclusions. In pregnant women with perinatal losses in history owing to autonomic nervous system disregulation a significant intensity of fetal regulatory systems and the centralization of fetal cardiac rhythm control were observed. The cardiotocography and cardiointervalography data with revealed signs of excessive sympathetic activation can serve as preclinical signs of gestational pathology. Key words: perinatal losses, fetal functional state evaluation, cardiotocography, cardiointervalography, autonomic nervous system.

Objective. The high prevalence of obesity in employable population dictates the necessity for preclinical diagnosis of diseases associated with it, including the study of the autonomic regulation of heart rhythm. The objective was to study the correlations between the adipocytokine profile and heart rate variability in patients with obesity. Materials and methods. 300 persons were examined, the average age was 46.2 6.4 years; Group 1 was metabolically unhealthy obesity phenotype (MUHOP) 90 patients; group 2 was obesity without metabolic disorders [Ob(+)MD(-)] (MHOP) 50 persons; the control group consisted of 100 healthy respondents. We studied the following indices: blood serum adipocytokines: leptin, insulin, resistin, adiponectin. Heart rate variability was studied using Poly-Spectrum Rhythm 2012 computer electrocardiograph. Results. In the course of the study, decrease in the total heart rate variability and reactivity of the parasympathetic part of the autonomic nervous system in patients from MUHOP group was found, while there were no differences with the control in the MHOP group. It was established that a decrease in the parasympathetic effect on the regulation of heart rhythm is associated with the presence of abdominal obesity, insulin resistance, and an increase in the level of TG, glucose, resistin, and uric acid. Conclusions. The received relationships between indicators of carbohydrate and lipid metabolism, the level of uric acid and adipocytokines with temporal and spectral characteristics of the autonomic nervous system confirm their contribution to the development of autonomic dysfunction in obese persons.

To manage autonomic disorders in adolescents with tuberculosis, 100 people from 12 to 15 years old were examined and randomly divided into two groups: Group 1 received standard anti-tuberculosis therapy, and in Group 2, additionally to standard therapy, comprehensive treatment with Magne B6 was used for 2 months, and then Valerian extract was used for another 2 months. For comparison, 50 healthy adolescents were examined. Before treatment, all adolescents with tuberculosis experienced a decrease in heart rate variability, a pronounced autonomic imbalance with the prevalence of sympathicotonia and overexertion of compensatory mechanisms. In Group 1, during the comprehensive treatment there were an increase in SDNN and Mo and decrease in AMo and tension index at rest. Active orthostatic test (AOT) was accompanied by a significant increase in SDNN, Mo and a decrease in AMo, which indicated an increase in the activity of the parasympathetic autonomic nervous system and decreased activity of the sympathetic autonomic nervous system. In the group receiving standard therapy, hypersympathycotonia persisted and manifested through significant (p < 0.05) reduction in such parameters as SDNN, increased heart rate, AMo, and Mo shift to short intervals. Medication management resulted in the vegetative balance by increasing heart rate variability, reducing hypersympathicotonia, improving the autonomic support of the cardiovascular system at rest and during AOT.

The article presents the results of the use of speleoclimatotherapy in recreational activities in children of primary school age. In the course of the study, we analyzed indicators of heart rate variability in children depending on the initial vegetative status. In vagotonics and normotonics, there was an increase in the activity of the sympathetic division of the autonomic nervous system, and in sympatotonics, there was a decrease in HRV parameters within the age norm, characteristic of increased activity of the sympathetic division of the autonomic nervous system. Such changes can occur when the adaptive reserves of the childs body increase. However, when using speleoclimatotherapy during recreational activities, it is necessary to take into account the initial level of vegetative activity of heart rate regulation in children.

Introdução: Existem poucos estudos que evidenciam a manipulação vertebral relacionada à modulação autonômica cardíaca. Objetivo: Revisar a literatura sobre os efeitos da manipulação vertebral sobre a modulação autonômica cardíaca. Métodos: Foi realizada uma busca bibliográfica nas bases de dados da saúde Medline, Pubmed e Cinahl, no período correspondido entre setembro e novembro de 2014. Foram utilizados os descritores em inglês Spinal Manipulation, Cardiac Autonomic Modulation, Autonomic Nervous System, Heart Rate Variability, além de associações entre eles. Resultados: Foram encontrados 190 artigos, sendo excluídos 39 por serem repetidos, restando 151. Destes, 124 não se encaixaram nos critérios de inclusão e após leitura crítica e análise dos materiais foram selecionados 7 artigos. Grande parte dos estudos revelou que a manipulação da coluna, independente do segmento, demonstra alterações autonômicas, tanto em nível simpático quanto parassimpático. Conclusão: Existem diferentes metodologias para avaliação da modulação autonômica cardíaca, sendo a Variabilidade da Frequência cardíaca através do eletrocardiograma a mais utilizada. A manipulação vertebral exerceu influência, na maioria dos artigos, sobre a modulação autonômica cardíaca.Palavras-chave: manipulação da coluna, sistema nervoso autônomo, variabilidade da frequência cardíaca.
