The vegetative nervous system state in 60 pregnants with late hestosis (with terms of 36 40 weeks is studied. The vegetative response types using mathematical analysis of cardiac rhythm variability in rest and in test with active orthostasis and phychologic peculiarities of a person are determined. The peculiar type of vegetative response especially in vegetative provision of activity as well as revealed psychovegetative syndrome can be connected with suprasegmental part disfunction of vegetative nervous system, in particular, its ergothropic part and with intrasystemic disintegration of the brain.

Purpose: Conduct an analysis of cardiac rhythm variability in the cows of the Jersey breed with a different vegetative status.Materials and methods. Indicators of the electrocardiogram (ECG) and cardiac rhythm variability studied on cows of the Jersey breed (n = 103). For the analysis and removal of ECG, the animal studied used the program «Conan-4.5» in the system of frontal administrations according to the method of P. M. Roshchensky. Clinical research methods were carried out according to the methods of clinical inspection of animals B. V. Ears and included — inspection, palpation, percussion and auscultation of the heart area.Results. Among the entire studied array of animals, the largest amount was sympathyone — 50,5%, normotonics — 24,3%, hypersympathicotonics — 16,5%. The smallest amount — vagotonic — 8,7%. For the vagotonic, the respiratory modulation index was 8,16±0,02%, the index of the sympathetic system is 43±0,1%, and the index of slowly wave arrhythmia is 0,8±0,1%. This group of cows parasympathetic (software) prevails over the sympathetic department of the vegetative nervous system. For normotonics, the value of the respiratory modulation index was 4,14±0,03%, the index of the sympathetic system is 96±0,2%, and im is 2,5±0,2%. This group is characterized by an equilibrium state between sympathetic department and VNS. The ids for sympathicotonists amounted to 2,78±0,03%, the index of the sympathetic system is 195±0,2%, and im is 8,2±0,1%. At sympathicotonists, which are characterized by a predominance with VNS above software. The hyper smpathetical respiratory modulation index was 1,34±0,02%, ICAS — 588±0,1%, and im is 11,4±0,3%. In hypersympathicotonists, which are characterized by the predominance of the super-viper vehicle of the vegetative nervous system over parasympathetic.Conclusion. The separation of the entire array on the subgroups based on the vegetative status of animals was based on the indicators of the voltage index of regulatory systems. To confirm the correctness of the separation of the studied array of animals on the subgroup, statistical processing was carried out and a classification matrix was built. Also, to confirm the classification separation matrix, additional statistical processing of the material of the differences between the obtained groups in the square of the distance of the Mahalonobis D2 was carried out. In the course of further registration and mathematical analysis of the variability of the heart rate of cattle (cows of the Jersey breed) with the help of a modern complex electrophysiological laboratory «Conan-4.5» features of indexes of A. Ya. Kaplan were established.

Adaptive Reactions

According to modern data, the cardiovascular system is a kind of indicator of the organism's adaptive activity, and the structure of the heart rhythm carries information about the development of adaptive reactions in response to irritating factors of the external and internal environment.The aim of the study – to investigate the functional state of the autonomic nervous system in pregnant women who have harmful habits by evaluating and analyzing the parameters of heart rate variability in order to prevent complications of non-delivery of gestational process.Materials and Methods. The study involved 73 pregnant women, 53 of them were pregnant (the main group) who had malignant habits in history. Before studying adaptive reactions in pregnant women, a study of cardiac rhythm variability was performed in practically healthy non-pregnant women of reproductive age (25.3±2.2) years). The control group consisted of 20 pregnant women without any harmful habits. Determination of heart rate variability was performed on the basis of peripheral heart rate recording, which included measuring the sequence of RR intervals for 5 minutes, followed by mathematical analysis using the PlsMntr software product.Results and Discussion. It was established that in the main group, in the complicated failure to pass the gestational process, violations of cardiac rhythm variability were detected in 59.7 % of cases. There is an increase in the frequency of very low frequency (VL F) waves (43.5 % relative to control, p<0.05), indicating a predominance of humoral and metabolic rate of regulation of the cardiac rhythm. At the threat of premature births, a decrease in the particle (LF) is observed at 36.6 %, a decrease in the share of high-frequency waves (НF) by 30.8 %. Taking into account the results of the study, one can speak of a decrease in the tone of the sympathetic and parasympathetic nervous system, reducing the influence of the reflexive vegetative level of regulation, which, in turn, indicates the depletion of regulatory mechanisms and the lack of an adaptive protective effect of n.vagus on the heart.Conclusions. Our innovative low-invasive method of evaluating the adaptive reactions of the organism through the determination and analysis of indicators of cardiac rhythm variability in pregnant women with the existing harmful habits offers us the opportunity to observe manifestations of functional stress of regulatory systems of pregnant women, preceding the development of complication of non-delivery of gestational process.

The purpose of our research was to estimate the brain blood supply level by rheoencephalography method in junior students of the Medical academy and to determine the blood supply links with the autonomic regulation state, behavioural and alimentary factors. Rheo-encephalographic study, research of the autonomic nervous system state, heart rate regulation and questioning of 17–29 year-old students have been conducted. Basic hemodynamic indices were normal in all surveyed students. Increase in body weight index enhanced the probability of the brain blood supply deterioration. Adaptation mechanisms tension was accompanied by reduction of the rheographic index. Higher blood filling of the brain vessels corersponded to higher ratio “blood minute volume / due blood minute volume” defined taking into account the system arterial pressure. The quantity of links with indicators of the autonomic nervous system state was limited. Nonlinear dependence of the rheographic index on the Kerdo vegetative index was observed: the rheographic index value was the lowest in students with the autonomic balance by the Kerdo vegetative index; it was the highest in the group with the sympathetic prevalence. Risk factor of blood filling decrease was the reduction in the diet variety when foodstuffs of different groups were included into the diet less than twice a week, or they were excluded from the diet completely. Positive correlation of blood supply was observed more often with frequent consumption of fish, vegetables, and fresh fruits. Increase in the regular alcohol intake experience promoted decrease in brain blood supply and increase in asymmetries of blood supply indicators. The effect of alcohol was essential, despite young age of surveyed students and low level of alcohol consumption. Increase in the experience and intensity of smoking was accompanied by deterioration of brain blood supply indicators. Students with the best blood supply had the better academic progress. Observed multiple correlations of blood supply indicators with behavioural factors allowed to assert that reduction of risk factors (control of body weight, variety and full value of a diet, refusal of smoking, alcohol restriction even below doses which are considered safe) would allow to improve the brain blood supply.

There are presented the results of combined examination of the state of vegetative nervous system in 94 patients with rheumatoid arthritis. By studying the variablity of cardiac rhythm in the sphere of vegetative regulation in patients dominance of sympathic tonicity mainly with asympathicotonic reactivity and deficient vegetative support of activity is determined. In majority of patients (90,4%) symptom complexes of vegetative dysfunction are found. Inclusion of dimephosphonum in combined therapy of rheumatoid arthritis led to normalization of indices of vegetative regulation and to significant diminishing of clinical manifestations of vegetative dysfunction.

State of initial vegetative tonus in 68 children of age from 7 to 13 with congenital heart diseases (of acyanotic type) was studied by mathematical analysis method of cardiac rhythm variability at pre-operation and post-operation periods. It was established, that in patients with congenital heart diseases dynamics peculiarities of vegetative nervous systems state depend on operations conditions and character of initial vegetative tonus in pre-operation period. It was determined, that most unfavourable days with great variation of vegetative characteristics are the 1st, 2 nd and also the 5 th and the 6 th days. The above said should determine therapy tactics with taking into account vegetative regulation.

Data which were obtained last time allow to re-comprehend ideas concerning mechanisms of cardiac rhythm regeneration and demonstrate existence of rhythm generator in the central nervous system in addition to such in the heart itself. Intracardiac generator is a life-supporting factor which supports pumping function of the heart while central nervous system is in deep inhibition status. Central generator provides adaptive reactions of the heart in natural medium. Integration of the two hierarchic levels of rhythmogenesis provides reliability and functional perfection of cardiac rhythm generation system in the organism.

Generation of monoclonal antibodies (MAbs) against tissue antigens has yielded several (VC1.1, HNK- 1, L2, 4F4 and anti-leu 7) which recognize the unique sugar epitope, glucuronyl 3-sulfate (Glc A3- SO4). In the central nervous system, these MAbs have demonstrated Glc A3-SO4 at the surface of neurons in the cerebral cortex, the cerebellum, the retina and other widespread regions of the brain.Here we describe the distribution of Glc A3-SO4 in the peripheral nervous system as determined by immunostaining with a MAb (VC 1.1) developed against antigen in the cat visual cortex. Outside the central nervous system, immunoreactivity was observed only in peripheral terminals of selected sensory nerves conducting transduction signals for touch, hearing, balance and taste. On the glassy membrane of the sinus hair in murine nasal skin, just deep to the ringwurt, VC 1.1 delineated an intensely stained, plaque-like area (Fig. 1). This previously unrecognized structure of the nasal vibrissae presumably serves as a tactile end organ and to our knowledge is not demonstrable by means other than its selective immunopositivity with VC1.1 and its appearance as a densely fibrillar area in H&E stained sections.

Ocellar Nerve

Barnacles are very specialized Crustacea, with strongly reduced head and abdomen. Their nervous system is rather simple: the brain or supra-oesophageal ganglion (SG) is a small bilobed structure and the toracic ganglia are fused into a single ventral mass, the suboesophageal ganglion (VG). Neurosecretion was shown in barnacle nervous system by histochemical methods and numerous putative hormonal substances were extracted and tested. Recently six different types of dense-core granules were visualized in the median ocellar nerve of Balanus hameri and serotonin and FMRF-amide like substances were immunocytochemically detected in the nervous system of Balanus amphitrite. The aim of the present work is to localize and characterize at ultrastructural level, neurosecretory neuron cell bodies in the VG of Balanus amphitrite.Specimens of Balanus amphitrite were collected in the port of Genova. The central nervous system were Karnovsky fixed, osmium postfixed, ethanol dehydrated and Durcupan ACM embedded. Ultrathin sections were stained with uranyl acetate and lead citrate. Ultrastructural observations were made on a Philips M 202 and Zeiss 109 T electron microscopy.
