RATIO OF TOTAL SLOW AND SUPER SLOW CEREBRAL BIOELECTRICAL ACTIVITY IN CHILDREN WITH HYPOXIA

The aim of the study is to identify changes in the total slow and super slow bioelectric activity of the cerebral hemispheres in 8–11-year-old children under reduced oxygen partial pressure in the inhaled air and in norm. Materials and Methods. The authors examined 82 8–11-year-old children. EEG registration was carried out on a complex Russian device "Telepat-103" with computer processing of the results. Slow potentials were recorded using a special computer complex for studying constant potential level (CPL) and cerebral energy consumption "Neuroenergon". Hypoxia was created by a special medical device "Hypoxicator" (Trade Medical). The choice of the oxygen content in the test hypoxic mixture (14 % O2) was based on the results of a three-stage hypoxic test carried out before the complex examination. Results. Hypoxia increases the index and amplitude of delta oscillations and decreases the number of alpha waves in 8–11-year-old children. The results obtained indicate that it is more important to provide the brain with a sufficient amount of oxygen corresponding to its needs than simply to increase the brain blood supply during hypoxia. The study also indicates the contribution of the body's sensitivity to hypoxic response. Under hypoxia, an increase in the constant potential level in the studied brain areas is observed in 8–11-year-old children. An increase in electrical activity during normobaric hypoxia is noted at low baseline values of constant potential level. An increase in the slow electrical brain activity occurs due to the change of brain energy supply according to the biochemical indicators of energy metabolism. Short-term hypoxia is accompanied by a simultaneous increase in slow-wave activity due to delta activity and CPL in 8–11-year-old children. Conclusion. Thus, we can say that a picture of functional brain activity with simultaneous inhibitory phenomena in the cortex is formed. It may reflect the development of a special state of the central nervous system. Key words: constant potential level, electroencephalography, hypoxia, adaptation to hypoxia. Цель работы – выявление изменений суммарной медленной и сверхмедленной биоэлектрической активности полушарий головного мозга у детей в возрасте от 8 до 11 лет в условиях нормального и сниженного парциального давления кислорода во вдыхаемом воздухе. Материалы и методы. Обследовано 82 ребенка 8–11-летнего возраста. Регистрация ЭЭГ осуществлялась на комплексной отечественной установке «Телепат-103» с компьютерной обработкой результатов. Медленные потенциалы фиксировались с помощью специального компьютерного комплекса для исследования уровня постоянных потенциалов (УПП) и энергозатрат головного мозга «Нейроэнергон». Гипоксические условия создавались аппаратом «Гипоксикатор» фирмы Trade Medical. Выбор содержания кислорода в тестирующей гипоксической смеси (14 % О2) основывался на результатах проведенного до комплексного обследования трехступенчатого гипоксического теста. Результаты. У детей от 8 до 11 лет действие гипоксии на головной мозг приводит к возрастанию индекса и амплитуды дельта-колебаний и убыванию числа альфа-волн. Полученные результаты говорят о том, что большое значение имеет не столько усиление кровоснабжения головного мозга при гипоксии, сколько обеспечение мозга достаточным, соответствующим его потребностям, количеством кислорода, а также о роли чувствительности организма к гипоксии. При воздействии гипоксии у детей этого возраста наблюдается возрастание уровня постоянных потенциалов в исследуемых областях головного мозга. При низких фоновых значениях уровня постоянных потенциалов отмечается возрастание электрической активности при нормобарической гипоксии. Возрастание медленной электрической активности головного мозга происходит из-за того, что изменяется энергообеспечение головного мозга по биохимическим показателям энергетического обмена. Действие кратковременной гипоксии сопровождается одновременным возрастанием медленноволновой активности за счет дельта-активности и УПП у детей от 8 до 11 лет. Выводы. Таким образом, можно говорить о том, что формируется своеобразная картина функциональной активности с одновременными тормозными явлениями в коре, что может являться отражением развития особого состояния центральной нервной системы. Ключевые слова: уровень постоянных потенциалов, электроэнцефалография, гипоксия, адаптация к гипоксии.

But there was no association found in the level of burnout and compassion satisfaction among subjects with their selected demographic variables.

Neurophysiological signs of changes in the functional state of the nervous system in patients with vibration disease associated with type 2 diabetes mellitus

Introduction. Neurofunctional state is an essential criterion in assessing the quality of the regulatory mechanisms of autonomic and somatic functions that determine the prognosis and course of vibration disease associated with type 2 diabetes mellitus (DM2). Objective of the study is to identify neurophysiological signs of changes in the functional state of the nervous system in patients with vibration disease caused by the combined effects of local and general vibration (VD com.) in combination with DM2. Materials and Methods. The group I included (n = 33) - VD com. patients, group II - 30 cases with VD com., burdened with DM2. We used neuroenergy mapping (NEM), registration of somatosensory evoked potentials (SSEP). Statistica software was used for statistical processing. Results. Analysis of the severity of changes in DC-potential level in both groups established a statistically significant predominance of persons with an increased average DC-potential level.

TELAAH SOSIOLOGIS PENYEBAB PELANGGARAN PENGUASAAN TANAH DI LINGKUNGAN PESISIR DI KABUPATEN LAMPUNG SELATAN

Cultivation in coastal area usually did for business activity purpose against the villagers without giving concern for the nature & ecosystem impact. Coastal area have high level of potential conflict either marine aspect nor land authorization. Misuse & violation against coastal area indicate by construction frequently founded along shoreline. Restricted ban against shoreline is a prohibition that require villagers to not build a construction long 100 meters from shoreline. The law against shoreline intend to protect the villagers from tsunami and environmental damage thru human behavior. South Lampung District have high potential level of tsunami by reason the location is close to Krakatau Mountain. In advance of Tsunami 2018 which rushed Banten & South Lampung District throw a big disadvantage and had public nor government attention. In fact, there are a lot of construction who violate shoreline regulation. This research using empiric method which elaborate with direct observation. Faced by the low government supervision reveal the low level of villagers legal awareness about obligations and social function of the land as well as urgency of the preservation of environmental functions on the coast. Masyarakat wilayah pesisir kerap menggunakan pesisir untuk melakukan kegiatan usaha tanpa memikirkan dampak terhadap lingkungan & ekosistem. Wilayah pesisir rentan menjadi sumber konflik baik dari segi kelautan maupun penguasaan atas tanah wilayah pesisir. Penyalahgunaan & pelanggaran terhadap wilayah pesisir ditandai dengan kerap ditemukan bangunan yang berdiri di sepanjang pesisir yang melanggar ketentuan Garis Sempadan Pantai (GSP). Larangan mendirikan bangunan di sepanjang garis sempadan pantai adalah larangan terhadap masyarakat untuk tidak mendirikan bangunan di sepanjang 100 meter dari garis pantai. Peraturan mengenai Garis Sempadan Pantai sejatinya bertujuan untuk melindungi masyarakat dari bahaya tsunami dan kerusakan lingkungan yang ditimbulkan oleh ulah manusia. Wilayah Kabupaten Lampung Selatan merupakan wilayah yang rentan akan bahaya tsunami dikarenakan lokasinya yang berdekatan dengan Gunung Krakatau. Pada Tsunami 2018 silam, wilayah Kabupaten Lampung Selatan merupakan salah satu wilayah yang terdampak bencana Tsunami Selat Sunda. Diketahui banyak ditemukan bangunan yang rusak akibat peristiwa Tsunami 2018 silam pada wilayah Lampung & Banten. Kerugian yang ditimbulkan oleh tsunami 2018 silam telah menarik perhatian publik & pemerintah. Fakta menunjukan bahwa banyaknya bangunan yang berdiri melanggar ketentuan GSP. Penelitian ini menggunakan metode penelitian empiris melakukan pengumpulan data pustaka, observasi dan wawancara. Hasil penelitian terdapat kurangnya pengawasan yang dilakukan oleh pemerintah yang menyebabkan adanya kesadaran hukum yang kurang memadai dari masyarakat wilayah pesisir.

Sex-Related Differences in the Interhemispheric Asymmetry of Cerebral Energy Metabolism in Young People Living in the Arctic Zone of the Russian Federation

In the Arctic region, adaptive reactions of the body put pressure on its functional systems and are accompanied by changes in cerebral energy metabolism in the central nervous system. Despite the fact that patterns of interhemispheric asymmetry and interaction are part of the brain’s essential, fundamental mechanism, no data is currently available on the neurometabolic features of interhemispheric asymmetry in men and women living in the Arctic zone of the Russian Federation. The aim of this paper was to identify the differences in cerebral energy metabolism in men and women born and living in the Arctic zone of the Russian Federation with different types of interhemispheric asymmetry according to the distribution of DC-potential level. Materials and methods. The study involved 63 subjects (30 men and 33 women) aged 30–34 years born and living in Arkhangelsk. Cerebral energy metabolism was assessed using the 5-channel Neuro-KM hardware and software complex. Distribution of DC-potential level was analysed by mapping the monopolar values and calculating their gradients. To calculate interhemispheric asymmetry of cerebral energy metabolism, an interhemispheric gradient was used, i.e. the potential difference between the right and left temporal leads (Td-Ts). The obtained DC-potential level results were compared with average standard values. The results of the study indicate differences in the distribution of the processes of cerebral energy metabolism in men and women with different types of hemispheric dominance. The most balanced cerebral metabolism was identified in men with right hemisphere dominance and in women with left hemisphere dominance. The presence of sex-related differences in the hemispheric asymmetry of cerebral energy metabolism may reflect different strategies of adaptation to the climatic conditions of northern latitudes in men and women.

The Relationship between Neuropsychological Performance and Level of Direct Current Potential in Patients with Occupational Diseases from Exposure to Physical Factors

The aim of the study was to identify the peculiarities of neuropsychological indices disorders depending on changes in the level of constant potential in patients with occupational diseases as a result of physical factors.Materials and methods. The study involved 60 patients with vibration disease caused by local vibration (group I), 106 patients with vibration disease caused by combined exposure to local and general vibration (group II), 101 civil aviation pilots with an established diagnosis of professional sensorineural hearing loss (group III), and 50 healthy men (group IV, comparison group) who were not exposed to vibration and noise due to the specifics of their professional activities. Methods of neuro-energy mapping and neuropsychological testing were used.Results. In groups I–II, compared with group IV, an increase in local levels of constant potential (DC-potential level) in the central, right temporal, and central frontal parts of the brain (2.3 (6.5–3.8) mV; –0.3 (–2.1–2.1); 2.1 (–3.4–6.8) and –0.3 (–3.1–4.3); –2.24 (–6.4–3.8); 0.9 (–3.1–8.5) mV at p = 0.005, 0.007 and 0.004 respectively). Differences in the values of DC-potential level gradients in individuals of group III when compared with group IV reached the level of significance in the central, temporal, occipital leads relative to the central frontal (–5.0 (–13.1–3.8); –4.1 (–9.4–5.1); –2.1 (–10.9–6.6); –6.3 (–15.3–1.8) and 2.9 (–3.0–10.6); 2.2 (–4.5–13.8); 5.6 (–7.6–14.1); –1.4 (–7.5–3.9) mV at p = 0.008; 0.009; 0.009, and 0.007 respectively). Cognitive disorders in patients of groups I–III when compared with group IV correspond to a mild disorder of dynamic, constructive praxis and expressive speech (1.40 (0–1,6); 1.43 (0–1,7); 1.2 (0–1,5) and 0.3 (0–1); 0.2 (0–1); 0.06 (0–1) points at p = 0.008, 0.008 and 0.009 respectively).Conclusions. A common neurofunctional sign of a mild impairment of the cognitive sphere in occupational diseases caused by physical factors is an increase in direct current potential level in the frontal-central and parieto-occipital regions, predominantly of the left hemisphere of the brain.

Sex Differences in Cerebral Energy Exchange Among Residents of the Arctic Zone of the Russian Federation

This article presents the sexual characteristics of cerebral energy metabolism in young residents of the Arctic zone according to the distribution of the level of direct constant potential (DC-potential level) of the brain. The study involved 60 people (27 men and 33 women) aged 30-34 years, born and living in the Arctic territory. Assessment of cerebral energy exchange was carried out using a 5-channel hardware-software diagnostic complex «NeuroKM». The distribution of the DC-potential level was analyzed by mapping monopolar values and calculating their gradients. For statistical data processing, the SPSS Statistics26 software package was used. The obtained DC-potentials level results were compared with the average statistical standard values. As a result of the study, gender differences in cerebral energy exchange were revealed in working-age residents born and living in the Arctic zone, depending on gender. In the group of men, there is a higher intensity of cerebral energy exchange in the whole cerebral cortex, the absence of pronounced hemispheric dominance, activation of the central and frontal cortex. In women, there is no predominance of energy exchange in any one area, there are low total indicators, activation of the central and occipital regions of the cortex; connection of the central cortex with the temporal, right-hemisphere dominance of cerebral energy exchange processes. Conclusion. Men are characterized by centralization and tension of regulatory systems, which can be an unfavorable factor in ensuring long-term adaptation to the climatic conditions of the Arctic. Women have a more optimal level of cerebral energy exchange.
