Autonomic Nervous

The main role in maintaining the functioning of the body, its growth, and development belongs to protein. It is involved in the formation of the muscular skeleton and is s part of enzymes, neurotransmitters, hormones. The effect of the autonomic nervous system on total protein metabolism has not been sufficiently studied. It is known that the autonomic nervous system is a structure that is responsible for the homeostasis and stability of the whole organism. It participates in the regulation of the heart, endocrine and external secretion glands, gastrointestinal tract, excretory organs, and more. In our studies, it was found that in chickens of Cobb 500 strain with different tones of the autonomic nervous system during the growing period from the 35th to the 60th day, different contents of total protein, albumin, and globulins were observed and different body weights were recorded. Vagotonic chickens showed the lowest protein metabolism at the age of 35 and 45 days (P ˂ 0.05–0.001) compared with sympathicotonics and normotonics, which tended to increase between 35 and 60 days of rearing compared with other groups of birds, where the studied protein fractions on the contrary decreased. Correlations between total protein, albumin, and bird body weight had a high linear relationship in all groups of chickens (P ˂ 0.05–0.001) and a negative relationship between the 45th and 60th days of rearing in sympathicotonics and normotonics. In birds with a predominance of parasympathetic tone of the autonomic nervous system, this correlation maintained its direction with high reliability (P ˂ 0.05) between body weight and total protein on the 60th day of rearing.

Emotional Strain

To determine the features of the cardiovascular system functional state in students using some indicators of heart rate variability under emotional strain. The research involved 67 male students with an average level of daily motor activity. The age range corresponded to 18 - 23 years. All the examined in the personal history had no deviations in health status and were considered to belong to the main medical group. The tonic activity of the autonomic nervous system in the normal condition was determined using the rhythmocardiographic method on the “Varicard 2.51” hardware-software complex according to the indicators of heart rate variability mathematical analysis. Cardio intervals were recorded in the normal condition and under conditions of emotional stress (the examination session was a model of stress). The analysis of heart rate variability was carried out on the basis of the statistical analysis indicators evaluation - SDNN, pNN50 and variational pulsometry - Mo, AMo, MxDMn, IN. Depending on the initial tonicity of the autonomic nervous system, all examined students were divided into groups: vagotonics, normotonics and sympathotonics. Among the determined values, the examination stress had the greatest impact on the stress index and the share of neighboring RR intervals, which differ by more than 50 ms. If the stress index significantly increased in students with vago- and normotonia, the proportion of neighboring RR intervals, differing by more than 50 ms, decreased in all the studied groups Taking an exam led to psycho-emotional stress of the body. It caused autonomic provision restructuring of cardiac activity due to an increase in the sympathetic effect. The results of the research may be of interest to all participants of the educational process.

Autonomic Nervous

The tone of the autonomic nervous system, protein metabolism and enzymes in Cobb-500 crossbred chickens aged 35 and 60 days were studied. The experiment involved 24 chickens, 8 in each group. In birds, the tone of the autonomic nervous system was determined by the method of variation pulsometry. The essence of the method is to record the effect of sympathetic and parasympathetic systems on heart rate in chickens. The effect was determined by recording one hundred consecutive cardio intervals and counting the time interval between each cardiocycle. Venous blood samples were taken from each individual at the age of 35 and 60 days to determine the indicators of protein metabolism (total protein, albumin, globulins) and lipid peroxidation depending on the tone of the autonomic nervous system. It was found that the antioxidant level in chickens with a predominance of the sympathetic division prevailed in all other groups regardless of the age of the bird. At 35 days of age, plasma concentrations of diene conjugates were significantly higher in normatonics and vagotonics (P ˂ 0.05). There was a higher level of activity of ketodienes and Schiff bases in chickens with a predominance of the sympathetic division of autonomic nervous regulation compared with normotonics and vagotonics (P ˂ 0.01). The content of total protein, albumin and globulins prevailed in normotonic hens and was the lowest in vagotonic hens at the age of 35 days. The two-month-old bird with a dominant parasympathetic division of the autonomic nervous system and normotonic hens had the highest levels of total protein, globulins, and conversely, sympathicotonic hens outnumbered the latter in albumin levels. Histidine content was highest in chickens with a balanced type of autonomic nervous system compared to sympathicotonics and vagotonics (P ˂ 0.05). The concentration of sulfur-containing amino acid methionine was highest in vagotonic chickens (P < 0.05) compared with sympathicotonics. Threonine was highest in sympathicotonics compared with other groups of animals and significantly outweighed vagotonics (P < 0.05). The level of lipid peroxidation products in 60-day-old sympathicotonic chickens was consistently higher in contrast to normotonics and vagotonics. At the same time there was the smallest increase in the activity of diene conjugates and ketodienes (P < 0.05) in chickens with a dominant sympathetic division of the autonomic nervous system, which indicates a slowdown in the accumulation of the final products of lipid peroxidation.

Autonomic Nervous

The tone of the autonomic nervous system, protein metabolism and the activity of the antioxidant system in Cobb-500 cross chickens aged 35 and 60 days were researched. The experiment involved 24 chickens, 8 in each group. In birds, the tone of the autonomic nervous system was determined by the method of variation pulsometry by recording the influence of the sympathetic and parasympathetic systems on the heart rate in chickens. The effect was determined by counting one hundred consecutive cardio intervals and the time interval between each cardiocycle. Venous blood samples were taken from each individual at the age of 35 and 60 days to determine protein metabolism (total protein, albumin, globulins), enzymatic and non-enzymatic links of the antioxidant system and lipid peroxidation depending on the tone of the autonomic nervous system. It was found that the antioxidant level in chickens with a predominance of the sympathetic division prevailed in all other groups regardless of the age of the bird. At 35 days of age, plasma concentrations of diene conjugates were significantly higher in normatonics and vagotonics (P ˂ 0.05). There was a higher level of activity of ketodienes and Schiff bases in chickens with a predominance of the sympathetic division of autonomic nervous regulation compared with normotonics and vagotonics (P ˂ 0.01). The content of total protein, albumin and globulins prevailed in normotonic hens and was the lowest in vagotonic hens at the age of 35 days. The two-month-old bird with a dominant parasympathetic division of the autonomic nervous system and normotonic hens had the highest levels of total protein, globulins, and conversely, sympathicotonic hens outnumbered the latter in albumin levels. Histidine content was highest in chickens with a balanced type of autonomic nervous system compared to sympathicotonics and vagotonics (P ˂ 0.05). The concentration of sulfur-containing amino acid methionine was highest in vagotonic chickens (P < 0.05) compared with sympathicotonics. Threonine was highest in sympathicotonics compared with other groups of animals and significantly outweighed vagotonics (P < 0.05). The level of lipid peroxidation products in 60-day-old sympathicotonic chickens was consistently higher in contrast to normotonics and vagotonics. At the same time there was the smallest increase in the activity of diene conjugates and ketodienes (P < 0.05) in chickens with a dominant sympathetic division of the autonomic nervous system, which indicates a slowdown in the accumulation of the final products of lipid peroxidation. It was found that the predominance of sympathetic tone is characterized by low activity of enzymes of the antioxidant system and tocopherol (P < 0.001, P < 0.01) at 35 and 60 days of age. Indicators of the activity of the antioxidant system had the highest level in vagotonic chickens of the studied age period (P < 0.05, P < 0.01, P < 0.001). The relationship between catalase and tocopherol levels in vagotonic chickens at 35 days of age, which increases at 60 days of age r = 0.53 (P < 0.01) was found.
