Background. Previously, we found a wide range of uric acid exchange parameters and functional relationships of uricemia and uricosuria with the parameters of immunity in healthy rats analyzed. The purpose of this study is to clarify such relationships in patients with neuroendocrine-immune complex dysfunction on the background of chronic pyelonephritis combined with cholecystitis in remission. Material and Methods. The object of observation were 34 men and 10 women aged 24-70 years old, who came to the Truskavets' spa for the rehabilitation treatment. The serum and daily urine levels of the uric acid by uricase method were determined. Immune status evaluated on a set of I and II levels recommended by the WHO. The condition of microbiota is evaluated on the results of sowing of feces and urine. Results. The canonical correlation analysis revealed that raw uricemia determines by 28% nine parameters of immunity (relative blood content of pan-lymphocytes and their CD4 +-, CD56 +-, 0-populations, relative content of polymorphonuclear neutrophils, intensity and completeness of their phagocytosis Staph. aureus and their bactericidal capacity, saliva content of IgG) as well as bacteriuria and content in E. coli feces. Uricemia, normalized by sex and age, determines by 25% another constellation of immunity parameters (relative CD8 + lymphocytes content, CIC, E. coli phagocytosis intensity and completeness, Staph. aureus phagocytosis activity and completeness) as well as content in E. coli feces with impaired enzymatic activity and Klebsiela&Proteus. Instead, uricosuria determines only four parameters of immunity and only by 11,5%. Conclusion. Endogenous uric acid has a modulating overall beneficial effect on a number of immune and microbiota parameters in both healthy rats and people with neuroendocrine-immune complex dysfunction.

zukow@umk.pl 4 OO Bohomolets' Institute of Physiology, Kyїv i.popovych@biph.kiev.ua AbstractBackground. Previously, we found a wide range of uric acid metabolism parameters and functional relationships of uricemia and uricosuria with the parameters of immunity in healthy female rats analyzed. It was found by canonical correlation analysis that both parameters of uric acid metabolism determine the immunity status of rats by 71%. The purpose of this study is to determine the features of immune status in rats with quantitatively and qualitatively different uric acid metabolism. Material and Methods. Experiment was performed on 60 healthy female Wistar rats 220-300 g. Among them 10 animals remained intact, using tap water from drinking ad libitum. The rats of others groups for 6 days administered through the tube various fluids. The serum and urine levels of the uric acid (uricase method) were determined. In the blood, the parameters of immunity were determined. From thymus and spleen made smears-imprints for counting splenocytogram and thymocytogram. For them, as well as immunocytogram and leukocytogram of blood, Shannon's entropy was calculated. Results. Screening of immune profiles of four quantitative and qualitative uric acid metabolism clusters revealed 6 functionalmetabolic patterns, two of which are quasilinear (enhancing and suppressing), with immune extremes at moderately elevated uricemia, two U-shaped with immune optimum at moderately reduced uricemia levels, as well as a non-reactive pattern. Discriminant analysis revealed 14 parameters of immunity, the constellation of which four clusters of metabolism of uric acid clearly distinguish. Conclusion. Endogenous uric acid exerts a modulatory immunotropic effect in healthy female rats.168

Relationships between changes in uric acid parameters metabolism and parameters of immunity and microbiota in patients with neuroendocrine-immune complex dysfunction.

Background. Previously, we found a wide range of uric acid exchange parameters and functional relationships of uricemia and uricosuria with the parameters of immunity in healthy rats analyzed. We continued our research along the same lines in the clinical observation of patients, who came to the Truskavets’ spa for the rehabilitation treatment. Relationships between uricemia and uricosuria, on the one hand, and immunity and microbiota parameters, on the other hand, have been identified. The purpose of this study is to further explore these relationships using the cluster and discriminant analyses. Material and Methods. The object of observation were 34 men and 10 women aged 24-70 years old, who came to the Truskavets’ spa for the rehabilitation treatment of chronic pyelonephritis combined with cholecystitis in remission. The serum and daily urine levels of the uric acid by uricase method were determined. Immune status evaluated on a set of I and II levels recommended by the WHO. The condition of microbiota is evaluated on the results of sowing of feces and urine. Results. Cluster analysis revealed 4 variants of uric acid metabolism by deviating uricosuria and uricemia from the norm in Z-scores. In 34% of individuals, moderate hypouricosuria (-0,97±0,11 Z) is combined with a lower borderline uricemia (-0,53±0,20 Z). In 25% of patients, lower-border uricemia (-0,70±0,22 Z) is accompanied by marked hyperuricosuria (+3,87±0,25 Z). In 24% of people, moderately elevated uricosuria (+1,26±0,14 Z) is combined with completely normal uricemia (+0,09±0,16 Z). Finally, in 17%, a similar level of uricosuria (+1,17±0,19 Z) is combined with marked hypouricemia (-1,89±0,14 Z). Discriminant analysis revealed 12 parameters of immunity and 5 parameters of microbiota, by which the clusters of uric acid metabolism are identified with 94,3 %% accuracy.Conclusion. Endogenous uric acid has a modulating overall beneficial effect on a number of immune and microbiota parameters in both healthy rats and people with neuroendocrine-immune complex dysfunction on background of chronic inflammatory diseases.

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.
