Introduction and aim. Earlier, by applying the water-immersion and restraint stress (WIRS) model, we reproduced primary attributes of stress and found that the severity of the damage to the gastric mucosa correlates with changes in ECG parameters, which indicate myocardial dystrophy. Further, it was found that such a connection is caused by the damaging effect on both targets of increasing the level of parathyroid hormone, as well as the production of aldosterone and catecholamines by enlarged adrenal glands. In addition, an increase in the level of corticosterone and sympathetic tone with a simultaneous decrease in vagal tone as well as serum calcitonin and testosterone cause damage to the gastric mucosa, but not to the myocardium. Such a constellation of neuro-endocrine reactions to stressors determines the severity of damage to the gastric mucosa and myocardium by 73%. The purpose of this study is to find out metabolic and immune accompaniments of electrocardiogram and gastric mucosa parameters in naїve and stressed rats. Material and methods. The experiment is at 18 male and 20 female Wistar rats. Over the 10 days, one animal remained intact and 3 other rats were exposed to WIRS. The next day after stressing, immune and metabolic parameters as well as ECG and gastric mucosa injuries was recorded. Results. Serum levels of Phosphates, Сatalase and α-LP Cholesterol as well as erythrocyte level of Potassium and Na,K-ATPase activity of the erythrocyte are positively correlated with ECG markers of myocardial damage, and negatively correlated with visual markers of damage to the gastric mucosa. Erythrocyte level of Sodium and serum levels of Potassium and Alkaline Phosphatase reflect the intactness of the gastric mucosa only. While serum level of Calcium reflects damage to the gastric mucosa. Taken together, the listed metabolic factors determine the morpho-functional state of the gastric mucosa and myocardium by 72% (R=0.851). Damage to the gastric mucosa and myocardium is more severe, the lower the bactericidal activity of blood neutrophils, and the greater the mass of the thymus. The spleen mass and the content of fibroblasts in the thymus are negatively correlated only with the severity of damage to the gastric mucosa, while the percentages of reticulocytes and lymphoblasts in the spleen are positively correlated with it. Finally, the higher the percentage of macrophages in the thymus, the deeper the damage to the myocardium. The canonical correlation between the listed immune parameters and markers of the two targets of stressors is very strong (R=0.809). Conclusion. Water-immersion and restraint stress causes changes in the neuro-endocrine-immune complex, which lead to changes in the metabolome and damage to the gastric mucosa and myocardium.
The researchers of the Truskavetsian Scientific School of Balneology have demonstrated that effect of balneotherapy at the Truskavets’ Spa on the physical working capacity of both healthy rats and different categories of patients is ambiguous. It is shown that various variants of actotropic effects are accompanied by characteristic changes in a number of body parameters. The purpose of this study was to identify neuro- endocrine, hemodynamic and metabolic accompaniments of actotropic effects of balneotherapy in men with maladaptation. Material and methods. The object of observation were 34 men (aged 23÷70 years) with maladaptation against the background of chronic pyelonephtis in remission phase, who came for rehabilitation at the Truskavets' Spa. The object of study: PWC, hemodynamics, HRV, EEG, adaptation hormones, blood and urine metabolites. The survey was conducted twice: on admission and after 7-10 dais of rehabilitation. Results. The analysis of individual changes revealed that balneotherapy in 18 patients did not significantly affect the level of fitness. In 9 patients balneotherapy caused an increase in PWC150 (direct difference: 0.57±0.12 W/kg) while in the other 9 patients the level of fitness decreased (direct difference: -0.42±0.03 W/kg). Discriminant analysis revealed 24 variables as characteristic accompaniment of the three variants of actotropic effects of balneotherapy. Among them, 2 are hemodynamic, 13 are neural, which reflect the entropy of EEG and HRV as well as delta-, theta- and beta-rhythms, 2 are endocrine, and 7 are metabolic. Classification accuracy is 100%. Conclusion. The multivariate actotropic effects of balneofactors are due to their multivariate effects on neuro- endocrine regulation and metabolism, which, apparently, is determined by the peculiarities of the individual reactivity of the body.
Ergometric physical working capacity (PWC) testing has a long tradition in occupational medicine for assessing whether a sufficiently high level of physical performance for coping with the daily work requirements is given. Physical performance and stress resistance of the body are considered one of the main objects of influence of adaptogens. The stress-limiting effect of bioactive Naftussya water known. Data on the influence of Naftussya on the muscular performance are ambiguous. We set ourselves the goal of comparing balneotherapy-induced individual changes in PWC with changes in some parameters of the nervous and immune systems, as well as erythron, hemostasis, and metabolism. Material and methods. The object of observation were 19 men and 3 women (age 26÷61 years, body weight 78÷100 kg) with urate urolithiasis and chronic pyelonephritis. The survey was conducted twice: on admission and after two weeks of rehabilitation at the Truskavets’ Spa. Registered PWC150, parameters of HRV, EEG, immunity, phagocytosis, erythron, hemostasis and metabolism. Results. The analysis of individual changes revealed that in 45,5% patients reduced fitness was completely normalized, however, in 54,5% patients, the normal level of fitness fell to the lower zone of the norm. Discriminant analysis revealed 5 EEG parameters, VLF band HRV as well as plasma alanine aminotransferase and bactericidal capacity of monocytes of blood, the changes of which are characteristic (classification accuracy 100%) for alternative variants of actotropic effects of balneotherapy. Conclusion. The alternative response of fitness to balneofactors occurs within the framework of the functional-metabolic continuum and the neuro-immune complex. A decrease in fitness to the lower normal zone is accompanied by the normalization of the reduced bactericidal capacity of blood monocytes, so we interpret this decrease as a “physiological payment” for it.
Aim: To investigate changes in oxidative stress indicators in rats under conditions of long-term ethanol exposure.
Materials and Methods: We studied the effect of prolonged exposure to ethanol on the activity of free radical processes in the gonads of rats of both sexes. Experimental animals were divided into 2 groups: Group I (control group) rats, which were injected with distilled water orally for 28 days; II group – which for 28 days were injected intragastrically with a 30% ethanol solution at the rate of 2ml/100g of body weight once a day.
Results: The conducted experimental studies showed that the level of free radicals increases in animals that were injected with ethanol for 28 days, as indicated by an increase in the ROS index by 1.6 times in males and 1.7 times in females. Lipid peroxidation processes are also activated, as evidenced by an increase in the level of initial products of the lipoperoxidation chain – HPL by 54.6%, intermediate products – TBP by 57.9% and final products – SHO – by 80.3% in males and by 68.2%, respectively , 80.9% and 84.6% in females. Along with this, the activity of oxidative modification of proteins in the organs of the reproductive system of the experimental group of animals also increased. In particular, the level of OMР370 in the testes of male rats increased by 89.1%, and OMР430 increased by 56.4% from the level of animals that were not given ethanol. In the ovaries of female rats, the level of OMР370 increased by 112.%, and OMР430 increased by 60.7% from the level of animals without simulating ethanol intoxication. Therefore, we were able to establish significant changes and disturbances in the processes of free radical oxidation in the organs of the reproductive system of animals under the toxic effect of ethanol, which can negatively affect the reproductive function and quality of offspring in animals that were simulated ethanol intoxication.
Conclusions: In animals of both sexes, under the conditions of chronic ethanol exposure, there is an increase in free radical oxidation indicators, namely ROS, lipid peroxidation, oxidative modification of proteins, and the growth indicators in females are more significant than in males. This indicates a negative effect of chronic ethanol intoxication on the state of the membrane structures of germ cells, with DNA damage, which can lead to a violation of the function of the genital organs.
