Analysis of Natural Antibodies during the Development of Phantom Pain Syndrome.

We determined natural antibodies (n-Abs) to the regulators of the main systems of biochemical homeostasis: ß-endorphin, serotonin, dopamine, histamine, orphanin, angiotensin, GABA, glutamate, bradykinin, vasopressin, thrombin, and α-2-macroglobulin in individuals with phantom pain syndrome (PPS), resulting from amputation after injury. It was established that each patient has an individual immunoprofile, but for all of them there was a significant increase in the level of antibodies to serotonin, histamine, and angiotensin, which reflect the chronicity of the pain syndrome and do not depend on the self-assessment of the severity of PPS. Determination of the role of regulators of biochemical homeostasis in the development of phantom pain showed that, at high, moderate, and weak severity of PPS, the biogenic amine and angiotensinergic systems are activated. A decrease in PPS intensity normalizes deviations in all immunological parameters. The levels of n-Abs for the pain (ß-endorphin) and analgesic (orphanin) systems are significant only at low PPS. Monitoring the individual profile of n-Abs to endogenous regulators allows us to obtain an objective picture of the pain status of the patient's body.

Comparative Determination of Natural Antibodies for the Assessment of the Cardiovascular System and the Level of Human Difficulty.

A comparative analysis of natural antibodies to ß-endorphin, angiotensin, dopamine, serotonin, parameters of the cardiovascular system and anxiety levels was carried out for 241 athletes of various qualifications and sports. The obtained indicators of the cardiovascular system were compared with reference values. A significant increase in the level of natural antibodies to angiotensin was established for all groups of athletes. In the case of dopamine, serotonin, these differences are associated with the qualification of the athlete, for ß-endorphin, differences in the level of the indicator depending on the sport were found. A group of individuals with high levels of situational and personal anxiety was found among highly qualified athletes. An increase in blood pressure in athletes of cyclic sports and martial arts is adaptive, and in athletes of speed-strength sports it leads to a change in the walls of the myocardium. As a result of the study, the possibility of a comprehensive determination of natural antibodies and functional indicators as diagnostic markers for assessing the state of the human cardiovascular system has been shown.

Analysis of Immunobiochemical Parameters in Overweight People in Assessing the Risk of Cardiovascular Diseases.

A comparative analysis of specific immunobiochemical parameters, including natural antibodies (NAb) to endogenous regulators of the cardiovascular system, adrenal and gastrointestinal hormones, was performed in students aged 18-22 years with normal and increased body weight (the body mass index from 18.5 to 24.9 kg/m2 and from 25 to 29.9 kg/m2, respectively). The serum content of NAb and hormones was determined by ELISA. The level of the studied indicators depended on the body mass index value. In overweight subjects, the main immune indicators of the biogenic amine system, renin-angiotensin system, and kinin system exceeded the normal. The cortisol level was higher than in subjects with normal body weight. Aldosterone secretion was less dependent on the ACTH content and was lower than in students with normal body weight. The content of cholecystokinin and gastrin corresponded to the values for overweight. These trends in hormone contents are a predisposing factor for further weight gain. Practical significance of the combined assessment of disturbances in the immunological and biochemical homeostasis has been established. Analysis of the adrenal and gastrointestinal hormones can predict the risk of weight gain, but at the same time, changes in the level of immunological indicators in subjects with increased body weight characterizes the possibility of developing cardiovascular pathologies.

Measurement of Immunological Parameters to Assess Human Body Readiness for Physical Load.

We measured the level of natural antibodies (nAb) to glutamate and GABA reflecting the balance of excitation and inhibition systems and involved in the adaptation processes in athletes receiving normalized physical activity in the dynamics of training (figure skaters, football players, and people actively involved in sports). It was found that each subject has an individual immunological profile and its parameters change in accordance with the training load. The measured levels of nAbs to GABA and glutamate correlate the physical activity of a person. The surveyed football players were divided into 3 groups according to the results of the analysis. Subjects of the first group had reliably high immunological indices in comparison with the control and were at the peak of physical form; in the third group, low immunological indices relative to the control indicated exhaustion and fatigue. The indicators of the second group corresponded to normal and demonstrated the resource of adaptation to load. The developed method can be used for assessing person's readiness for physical activity.

[The detection of antibodies to endogenous bioregulators for evaluating functional condition of health of portsmen.]

The evaluation of functional condition of health of sportsmen doing Greek Roman wrestling was implemented using detection of level of antibodies to serotonin, histamine, dopamine, glutamate, GABA, orphanine, endorphin, angiotensin. The study established a reliable increasing of level of antibodies to orphanine, ß-endorphin, GABA and glutamate under increasing of duration of physical load. The content of antibodies to other regulators of adaptation had no statistical difference. The developed technique can be applied in evaluation of objectification of functional condition of sportsman with purpose of selecting optimal training process.
