Background. It was recently shown by our group that bilirubin has a neurotropic activity. It is also shown that endogenous uric acid exerts a noticeable modulating effect on neuro-endocrine adaptation factors. In this study, we supplemented the constellation both of subjects of influence with other nitrogenous metabolites - urea and creatinine, and the objects of influence - with plasma levels of the main adaptation hormones and the severity of trait and reactive anxiety. Materials and Methods. The object of observation were almost healthy volunteers: 30 females (30÷76 y) and 31 males (24÷69 y). In basal conditions determined plasma levels of nitrogenous metabolites as well as cortisol, aldosterone, testosterone, triiodothyronine and calcitonin, estimated the severity of the trait and reactive anxiety, recorded the ongoing HRV and EEG. After 4 or 7 days, repeated testing was performed. Results. By constructing regression models, it was found that direct bilirubin determines the levels of psycho-neuro-endocrine parameters by 66,0%, free bilirubin by 56,7%, uric acid by 40,8%, creatinine by 37,6%, and urea - by 31,1%. Taken together, nitrogenous plasma metabolites determine the severity of trait, but not reactive anxiety, plasma levels of testosterone, cortisol and triiodothyronine, but not calcitonin and aldosterone, as well as a number of HRV and EEG parameters by 70,6%. Conclusion. Nitrogenous plasma metabolites, even in the absence of uremia, are able to influence the state of the psyche, autonomic and central nervous and endocrine systems, apparently through aryl hydrocarbon and adenosine receptors of neurons and endocrinocytes and/or directly.

Background. Earlier in an experiment on rats, we showed that the newly created sulfate-chloride sodium-magnesium drinking mineral waters of Truskavets’ spa have neuroendocrine and metabolic effects significantly different from daily water. Adhering to the principle "From experiment to clinic", we continued research in this direction with the participation of patients of the resort. Materials and Methods. The object of clinical-physiological observation were 34 men aged 23-70 years, who underwent rehabilitation treatment of chronic cholecystitis and pyelonephritis in remission in the Truskavets resort. The examination was performed twice, before and after a 7-10-day course of balneotherapy. All patients received bioactive water Naftussya, however, 11 men additionally drank water "Khrystyna", and the other 11 men - water "Myroslava". The subject of the study were the parameters of the neuroendocrine-immune complex and metabolism. Results. The complex balneotherapy by interval use of sulfate-chloride sodium-magnesium mineral waters with Naftusya water causes significant changes in the constellation of neuroendocrine, metabolic and immune parameters, which are different from the effects of Naftusya water monotherapy. Own effects of mineral waters are estimated by modeling. In general, the effects are physiologically favorable and have a normalizing nature. Conclusion. The newly created sulfate-chloride sodium-magnesium drinking mineral waters of Truskavets resort have favorable neuroendocrine, metabolic and immune effects on patients with chronic cholecystitis and pyelonephritis.

Background. Earlier we showed, by constructing regression models, that plasma nitrogenous metabolites (uric acid, urea, creatinine and bilirubin) are able to influence the state of the trait anxiety, autonomic and central nervous and endocrine systems. In this study of the same cohort, other methodological approaches were used. Materials and Methods. The object of observation were almost healthy volunteers: 30 females (30÷76 y) and 31 males (24÷69 y). In basal conditions determined plasma levels of nitrogenous metabolites as well as cortisol, aldosterone, testosterone, triiodothyronine and calcitonin, estimated the severity of the trait and reactive anxiety, recorded the ongoing HRV and EEG. After 4 or 7 days, repeated testing was performed. Results. By the method of cluster analysis, four groups were created, the members of which differ minimally from each other in terms of the constellation of nitrogenous metabolites, but differ maximally from the members of other groups. Using the method of discriminant analysis, it was found that nitrogenous clusters differ from each other in terms of sex, age, trait anxiety, as well as 30 neuro-endocrine parameters. Conclusion. The obtained data confirm and supplement previous data on the physiological psycho-neuro-endocrine activity of plasma nitrogenous metabolites.

Background. Earlier we found a strong urato-neural relationships in both men and women. Moreover, in women, the factor structure of the neural root is almost completely different from that in men. In addition, significant differences were found between the profiles of urato-neural correlations of women of reproductive age and postmenopausal women. The purpose of this study is to analyze the relationships between the plasma urea level and some psycho-neuro-endocrine parameters in the same cohort. Materials and Methods. The object of observation were almost healthy volunteers: 31 males (24÷69 y) and 30 females, from among them 18 postmenopausal (48÷76 y) and 12 of reproductive age (30÷45 y). In basal conditions we determined plasma levels of urea and adaptation hormones, estimated the severity of the trait and reactive anxiety, recorded the ongoing HRV and EEG. After 4 or 7 days, repeated testing was performed. Results. By building regression models with stepwise exclusion, it was found that in men plasma urea positively determines (R2=0,499) the level of circulating catecholamines and power spectrum density (PSD) of δ-, θ- and β-rhythms in different loci. In postmenopausal women, urea downregulates the amplitude and PSD of δ-rhythm in different loci, instead, it upregulates the PSD of α-rhythm in T5 locus, entropy of EEG in 2 loci and vagal tone. The degree of determination of neural parameters is 71,6%. In women of reproductive age the degree of determination of neural parameters is similar (69,9%), but the factor structure of the model is completely different. Urea upregulates the PSD of β-rhythm in F7 locus while downregulates the levels of reactive anxiety, vagal tone, entropy of EEG in 3 loci and P4-θ PSD as well as causes left lateralization of θ- and α-rhythms. Conclusion. Plasma urea has a modulating effect on EEG&HRV parameters, as well as reactive anxiety, but this effect is significantly different in men and women of different ages.

Background. The immunoneuroendocrinology became the foundation of the Truskavetsian Scientific School of Balneology. The focus of research was on the relationships between EEG and HRV parameters, EEG&HRV and leukocytogram, phagocytosis, cellular and humoral immunity as well as between changes in these parameters under the influence of adaptogenic factors Truskavets’ spa. The purpose of this study is relationships between plasma levels of major adaptogene hormones and EEG&HRV parameters at human with dysadaptation. Materials and Methods. The object of observation were 10 women 33-76 y and 10 men 37-67 y without a clinical diagnosis, but with the deviations from the norm in a number of parameters of the neuro-endocrine-immune complex as a manifestation of dysadaptation. Parameters of EEG and HRV as well as hormones levels before and after a one-week course of drinking of Naftussya bioactive water registered. Results. Using the method of canonical correlation analysis, it was found that the level of triiodothyronine is determined by the constellation of 17 EEGs and 4 HRVs parameters by 87,5%. The rate of determination of the cortisol level by 14 EEGs and 3 HRVs parameters is 83,7%, and aldosterone by the other 14 EEGs and 3 HRVs parameters is 80,0%. Neuromodulation of testosterone and calcitonin levels is characterized by sexual dimorphism. With the same coefficients of determination (92,4%), the regression model for testosteroneemia in women included 15 EEGs parameters and no HRV parameters, instead testosteroneemia in men is modulated by other 11 EEGs parameters and one HRV parameter. The level of calcitonin in women is determined by 86,2% by the constellation of 9 EEGs and 2 HRVs parameters, while in men by 83,5% by the other 5 EEGs and 4 HRVs parameters. Conclusion. Plasma levels of the main adaptation hormones are accompanied by specific patterns of EEG and HRV parameters.
