General non-specific metabolic, neuroendocrine and immune reactions to various water-salt loads in female rats

Background. This article begins with a series of articles on the effects on parameters of water-salt, nitrous and lipid metabolism, as well as the neuroendocrine-immune complex of mineral water, extracted from the bore located in the city Gertsa (Bukovyna, Ukraine). The chemical analysis prompted us to use waters Sophiya and Naftussya from spa Truskavets’ as a reference as well as an artificial salt analogue of Gertsa water, which contains no organic matter or trace elements. Materials and methods. Experiment was performed on 58 healthy female Wistar rats 240-290 g divided into 6 groups. Animals of the first group remained intact, using tap water from drinking ad libitum. Instead, the other rats received the same tap water as well as waters Sophiya, Naftussya, Gertsa and its artificial salt analogue through the probe at a dose of 1,5 mL/100 g of body mass for 6 days. The day after the completion of the drinking course in all rats the parameters of metabolism and neuroendocrine-immune complex were registered. Results. Screening registered parameters found 42 among them who in rats subjected to water-salt loads, significantly different from that of intact rats, but on average the same group of animals that received liquids with different mineralization and chemical composition. Conclusion. Takes place nonspecific (general) reaction neuroendocrine-immune complex and metabolism in water-salt load as such, regardless of the specific chemical composition of fluids applied

Role of organic carbon and nitrogen of mineral waters in their metabolic effects at female rats

Background. Organic substances, despite their presence in all drinking mineral waters, are still considered to be active only in the water of Naftussya type (which, due to mineralization less than 1 g/L, are not formally mineral), whereas the physiological activity of true mineral waters (which mineralization is greater than 1-2 g/L) are associated with electrolytes and trace elements. The purpose of this study was to clarify the role of organic carbon and nitrogen of mineral waters in their effects on certain parameters of metabolism. Material and Methods. Experiment was performed on 48 healthy female Wistar rats 240-290 g divided into 5 groups. Animals of the first group for 6 days administered a single tap water through the probe at a dose of 1,5 mL/100 g of body mass. In the second group we administered the water Naftussya from the Truskavets’ layer, in the third group the water Sophiya of the Truskavets’ field. The rats of the fourth group received the native water from the Gertsa (Bucovyna) field, and the last group its artificial salt analogue. The day after the completion of the drinking course in all rats some metabolic parameters were registered. Results. On the basis of the correlation analysis with step-by-step exclusion, four metabolites of blood as well as five metabolites of urine are included in the regressive model for organic carbon (R=0,697; R2=0,486; Adjusted R2=0,347; F(10,4)=3,5; p=0,0025). Organic nitrogen of mineral waters affects five metabolic parameters of urine only, but with approximately the same force (R=0,621; R2=0,385; Adjusted R2=0,312; F(5,4)=5,3; p=0,0008). Conclusion. Organic substances of mineral waters play an essential role in their effects on the parameters of metabolism

Features of neuro-endocrine and immune reactions to various water-salt loads in female rats

Background. Previously, we have shown that the weekly load of rats with water-salt solutions of different chemical compositions causes both general and specific reactions of the parameters of metabolism. The purpose of this study is to identify under these conditions specific neuroendocrine and immune responses. Materials and methods. Experiment was performed on 58 healthy female Wistar rats 240-290 g divided into 6 groups. Animals of the first group remained intact, using tap water from drinking ad libitum. Instead, the other rats received the same tap water as well as waters Sophiya, Naftussya, Gertsa and its artificial salt analogue through the probe at a dose of 1,5 mL/100 g of body mass for 6 days. The day after the completion of the drinking course in all rats some neuroendocrine and immune parameters were registered. Results. The method of discriminant analysis revealed 29 parameters of the neuroendocrine-immune complex (10 of them reflect the neuroendocrine regulation, 4 thymus mass and thymocytogram elements, 5 elements of splenocytogram, 10 elements of immunocytogram and leukocytogram of blood and parameters of phagocytosis), according to which the reaction on various water-salt loads are identified with an accuracy of 98.3%. Conclusion. The peculiarities of the reactions of the parameters of the neuroendocrine-immune complex are due to the content of water in sulfate, bicarbonate and magnesium, as well as organic carbon and nitrogen

Mineral waters, metabolism, neuro-endocrine-immune complex, s. 252.

Dedicated to the 75th anniversary of Volodymyr Illich Kozyavkin with gratitude for the support of the Truskavetsian Scientific School of BalneologyThe monograph systematizes these writers and highlights the results of their own priority experimental and clinical-physiological studies of the impact of drinking mineral waters of Ukraine on neuroendocrine regulation, metabolism and immunity of healthy rats and patients in the process of rehabilitation of chronic pyelonephritis and cholecystitis in remission. In line with the concepts of functional-metabolic continuum and neuroendocrine-immune complex using the methods of factor, discriminant and canonical correlation analysis, it is demonstrated that mineral waters have both similar and specific physiologically favorable modulating effects on the parameters of the studied body systems.

Vaccine breakthrough hypoxemic COVID-19 pneumonia in patients with auto-Abs neutralizing type I IFNs

Life-threatening `breakthrough' cases of critical COVID-19 are attributed to poor or waning antibody response to the SARS- CoV-2 vaccine in individuals already at risk. Pre-existing autoantibodies (auto-Abs) neutralizing type I IFNs underlie at least 15% of critical COVID-19 pneumonia cases in unvaccinated individuals; however, their contribution to hypoxemic breakthrough cases in vaccinated people remains unknown. Here, we studied a cohort of 48 individuals ( age 20-86 years) who received 2 doses of an mRNA vaccine and developed a breakthrough infection with hypoxemic COVID-19 pneumonia 2 weeks to 4 months later. Antibody levels to the vaccine, neutralization of the virus, and auto- Abs to type I IFNs were measured in the plasma. Forty-two individuals had no known deficiency of B cell immunity and a normal antibody response to the vaccine. Among them, ten (24%) had auto-Abs neutralizing type I IFNs (aged 43-86 years). Eight of these ten patients had auto-Abs neutralizing both IFN-a2 and IFN-., while two neutralized IFN-omega only. No patient neutralized IFN-ss. Seven neutralized 10 ng/mL of type I IFNs, and three 100 pg/mL only. Seven patients neutralized SARS-CoV-2 D614G and the Delta variant (B.1.617.2) efficiently, while one patient neutralized Delta slightly less efficiently. Two of the three patients neutralizing only 100 pg/mL of type I IFNs neutralized both D61G and Delta less efficiently. Despite two mRNA vaccine inoculations and the presence of circulating antibodies capable of neutralizing SARS-CoV-2, auto-Abs neutralizing type I IFNs may underlie a significant proportion of hypoxemic COVID-19 pneumonia cases, highlighting the importance of this particularly vulnerable population

Features of metabolic reactions to various water-salt loads in female rats

Background. In the previous article we reported that screening registered parameters of water-salt, nitrous and lipid metabolism as well as the neuroendocrine-immune complex found 42 among them who in rats subjected to various water-salt loads, significantly different from that of intact rats, but on average the same group of animals that received liquids with different mineralization and chemical composition. The purpose of this article is to find out the features of the reactions of the parameters of metabolism. Materials and methods. Experiment was performed on 58 healthy female Wistar rats 240-290 g divided into 6 groups. Animals of the first group remained intact, using tap water from drinking ad libitum. Instead, the other rats received the same tap water as well as waters Sophiya, Naftussya, Gertsa and its artificial salt analogue through the probe at a dose of 1,5 mL/100 g of body mass for 6 days. The day after the completion of the drinking course in all rats the parameters of water-salt, nitrous and lipid metabolism were registered. Results. Found that 16 metabolic parameters the maximum deviates from the level of intact rats under the influence of the salt analogue of Gertsa water, a smaller, but tangible effect is made by the Gertsa native water, even less effective waters Sofiya and Naftussya, instead of ordinary water is almost ineffective in relation to these metabolic parameters. The other 19 parameters deviates to a maximum extent from the reference level after the use of water Naftussya, fresh water is less effective, whereas quasi-isotonic liquids are practically inactive for these parameters. The remaining 13 parameters in animals that use normal water, deviates from intact control to the same extent as in the previous pattern, which, apparently, is also due to the stressful effects of the load course. Both Naftussya and Gertsa water and its salt analogue prevent the stress deviations of these parameters. Instead, by consumption of water Sofiya stresses deviations of these parameters is reversed. The method of discriminant analysis revealed 33 variables (among them 8 refer to plasma/erythrocytes electrolytes, 7 to electrolytes of urine, to other metabolic parameters of plasma 5 and urine 9, as well as glomerular filtration, canalicular reabsorption, diurese and urine osmolarity), the totality of which the metabolic reactions to various water-salt loads are identified (recognized) with an accuracy of 98,3%. Conclusion. The features of the reactions of the parameters of metabolism are due to the content in waters NaCl, SO42- as well as organic carbon and nitrogen
