Інсульт посідає перше місце за наслідками стійкої інвалідизації людей у всьому світі [1,2]. У 80 % пацієнтів після завершення гострого періоду розвивається поліморфна картина порушень рухових функцій: парез, синдроми спастичності та патологічних синергій [1,2]. Відновлення рухових функцій зумовлене активацією первинних моторних представництв навколоінфарктного регіону, тоді як розвиток малоадаптивних моделей рухового контролю пов`язують із комплексним процесом реорганізації, як ураженої, так й неураженої гемісфери [2,3]. Продемонстровано, що регрес парезу корелює із відновленням кортикоспінальної іннервації за даними транскраніальної магнітної стимуляції (ТМС). Водночас розвиток спастичності та патологічних синергій не має прямої залежності зі ступенем порушення кортикоспінальної іннервації. Дані порушення асоціюють зі складною малоадаптивною реорганізацією із залученням вторинних, іпсілатеральних моторних представництв, гіперактивацією контралатеральної півкулі та вивільненням підкоркової активності [3–6]. Як відомо з наукових джерел, для вивчення реорганізації функцій головного мозку застосовується поєднання методів ТМС та електроенцефалографії (ЕЕГ) [4,6,7]. У результаті вивчення змін біоелектричної активності головного мозку продемонстровано зниження активності альфа-ритму та уповільнення ЕЕГ в навколоінфарктному регіоні, що пов’язують з негативним прогнозом відновлення та вивільненням підкоркової активності [8–11]. Підвищення потужності дельта-ритму в інтактній півкулі асоційовано із міжгемісферною дисоціацією [12–14]. Відновлення альфаактивності у центральних регіонах асоційоване з фізіологічною реорганізацією. Збереження бета-активності в ураженій півкулі вказує на патологічну реорганізацію та відсутність відновлення. Зсув когерентності з контралатеральною півкулею та збереження потужності у бета-частотному діапазоні вказує на малоадаптивну реорганізацію [6,15–17]. Враховуючи високий рівень поширеності, тяжкість наслідків інсульту та недостатню вивченість механізмів реорганізації головного мозку, вважаємо актуальним та перспективним питанням вивчення реорганізації функцій","PeriodicalId":12101,"journal":{"name":"Experimental and Clinical Physiology and Biochemistry","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75414440","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Decamethoxine is a chemical compound [1, 10-decameth-ylene bis (N, N – dimethylmethoxycarbonylmethyl) ammonium dichloride] that has a wide range of antimicrobial actions on Gram - positive (staphylococcus, streptococcus, pneumococcus), Gram-negative (gonococcus, meningococcus) cocci, diphtheria corynebacteria, enterobacteria, pseudomonads, protozoa, dermatophytes, yeasts-like fungi of the genus Candida , chlamydia and viruses. Pathological processes that occur in the cells of the body when inflammatory processes and pathological conditions are caused primarily by the violation of regulatory systems, the activation of lipid peroxidation processes and the violation of antioxidant protective system. Since decamethoxine has hydrophilic and lipophilic properties, it can penetrate into cells, blood through surfaces of a wound, mucous membranes, skin, etc., and be transmitted by blood to different organs and tissues, thus causing a variety of biochemical effects, particularly regarding to the regulatory NO-synthase system of cells. In this respect the biological action of decamethoxine nisms of the cell, blood lymphocytes in particular. It activates the enzymes of the glutathione antioxidant system, stimulates the activity of arginase and inhibits the activity of the constitutive isoform of NO synthase with the simultaneous activation of the inducible isoform of NO synthase.","PeriodicalId":12101,"journal":{"name":"Experimental and Clinical Physiology and Biochemistry","volume":"23 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81010878","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The urgency is due to the fact that the vestibular analyzer provides a sense of position, movement of a human body and its parts in space, maintains a pose in all possible types of human activity, performs the function of the body equilibrium both at rest and during the process of movement. The question about the role of the vestibular system in compensation for the linear and angular accelerations that occur during arbitrary or unexpected movements has been investigated for many decades. The increased sensitivity of the vestibular analyzer does not at first glance cause an immediate threat to a humam life, however, it degrades its quality significantly. However, it has a progressive nature and is accompanied by insufficient compensation under stress. The reactions of the organism with increased sensitivity to the vestibular analyzer are investigated in the studies, aimed mainly at identifying the professional features of functioning tation mechanisms. The functional status of these individuals is impaired as a result of reduced functional and metabolic reserves of a body, especially in the III type of weather. The obtained data also correlate neuroticism with many important physiological indicators. The data described in the article add more to the understanding of the features of the body response to the vestibular load in people with increased sensitivity to the vestibular analyzer and can be used as a prognostic criterion during prophylactic medical examinations and in choosing a career.","PeriodicalId":12101,"journal":{"name":"Experimental and Clinical Physiology and Biochemistry","volume":"93 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74028276","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its main role is to maintain Na + and K + gradients across the plasma membrane by ATP-driven active transport. The Na + , K + -ATPase was one of the first ion pumps studied because of its importance in main-taining osmotic and ionic balances between intracellular and extracellular environments. Ad-ditional extracellular stimuli have been shown to induce internalization of the Na in the incubation medium, including the loss of endogenous phosphorus Pi in the membrane preparation, expressed in μmoles Pi per minutes per milligram of protein. The amount of endogenous phosphorus has been identified by the modified Fiske-Subbarow method, the quanti-tation of protein in the membrane preparation has been determined by Lowry method and the activation energy – in the Arrhenius coordinates. The activity of ouabain-sensitive ATPase under the change in the incubation medium temperature gradually increased at the stages of embryos development by an average of 23.4 ± 1.6% as compared with the control group. The maximum value of the enzymatic activity of Na + , K + pump of the embryos has been defined at the 8-stage of blastomers division (270 min). At the 6th hour of the development, no significant changes in the activity of Na + , K + -ATPase has been observed in comparison with the previous stage of the development. The results have shown that with the temperature change (10 o C) of the incubation medium, the Na + , K + -ATPase activity increased significantly at the investigated stages of the development. For Na + , K + -ATPase, a nonlinear dependence of the enzymatic activity on the temperature in the Arrhenius coordinates was found; the activation energy is 10.6 ÷ 20.8 kJ / mol. The calculated values of the Na + , K + -ATPase activation energy of the loach embryos during embryogenesis are consistent with the existing data and are likely due to the binding strength of the investigated ATP-hydrolase to membrane lipids during the embryonal cell division.","PeriodicalId":12101,"journal":{"name":"Experimental and Clinical Physiology and Biochemistry","volume":"101 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72944057","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
