The development of oxidative and nitrative stress and the processes of free radical oxidation are associated with many pathological processes. Damage of any origin leads to the activation of free radical processes not only in the place of damage, but also in the whole organism. The aim of the study is to assess the state of lipid peroxidation, content of GSH and GSSG and the activity of NO-synthase and arginase in lymphocytes and peripheral blood serum in men with erectile dysfunction due to combat trauma. The research was conducted on peripheral blood lymphocytes of men injured as a result of combat operations (shrapnel and bullet wounds) in the Russian-Ukrainian war, and who were treated at the Military Medical Clinical Center of the Western Region (Lviv, Ukraine). The research group of men with combat injuries was divided into two age groups: men aged 20–39 years and men aged 40–53 years. The MDA content in the blood serum of patients of both age groups was 1.35 times higher than in the control group. In peripheral blood lymphocytes, the MDA content in patients of the young age group was 1.27, and in patients of the middle age group in 1.39 times higher than in the control group. Simultaneously, no significant changes in the concentration of oxidized glutathione in blood serum and blood lymphocytes were found between men with erectile dysfunction due to combat trauma and healthy men. GSH content in blood serum in patients of both age groups was significantly lower than in the control group. The arginase/NOS ratio in blood serum was 9.75 times lower in the young age group and in 20.45 times lower in the middle age group compared to healthy men. It was established that in the blood serum and blood lymphocytes of men with erectile dysfunction due to combat trauma, processes of lipid peroxidation were intensified and the GSH level was reduced. The GSH/GSSG ratio was reduced only in blood serum. It was found that the oxidative stress is associated with development of nitrative stress. The arginase/NOS ratio was shifted towards increased NOS activity. Activation of iNOS was accompanied by significant inhibition of cNOS. Further study of biochemical mechanisms is important to understand the triggers of erectile dysfunction due to combat
trauma.

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.

У статті представлено дані про стан пероксидації ліпідів і активності ізоформ NOсинтази та аргінази лімфоцитів і сироватки периферичної крові у чоловіків, постраждалих внаслідок бойових дій (кульові та осколкові поранення). Були обстежені 68 чоловіків, постраждалих внаслідок бойових дій (осколкові та кульові поранення), які склали основну групу. До групи контролю були включені 48 практично здорових чоловіків. Пацієнти основної та контрольної груп були розділені на дві вікові підгрупи кожна: 20–39 років і 40–60 років. Вміст МДА у сироватці крові пацієнтів обох підгруп основної групи був в 1,4 рази вищий, ніж в осіб відповідних підгруп групи контролю (p<0,05). У лімфоцитах периферичної крові вміст МДА у пацієнтів обох вікових підгруп основної групи був 1,3–1,4 рази вищий, ніж в осіб відповідних підгруп групи контролю (p<0,05; p<0,01).
У сироватці та лімфоцитах крові чоловіків, постраждалих внаслідок бойових дій, суттєво зростає активність індуцибельного (Са2+ -незалежного) de novo синтезу NO. Водночас активність Са2+-залежної NO-синтази в лімфоцитах крові чоловіків, постраждалих внаслідок бойових дій, була нижчою в 2,4 рази у порівнянні з показниками практично здорових чоловіків (p<0,001), а в сироватці крові майже не змінювалася. Підтверджено, що у чоловіків, постраждалих внаслідок бойових дій, індуцибельна NOS може активувати процеси пероксидного окиснення ліпідів, оскільки зафіксовано прямий достовірний прямий кореляційний зв'язок високої сили між активністю Са2+-незалежної iNOS і вмістом МДА (r=0,74; р<0,05). Встановлений також вірогідний середньої сили кореляційний зв'язокміж активністю аргінази і вмістом МДА (r=0,52; р<0,05).
