It is known that the basis of the complex functional organization of the central nervous system (CNS) is the coordinated interaction of the main processes of nervous action-excitation and inhibition. In the CNS, these processes are carried out through neurotransmitters (mediators). Neurotransmitters affect the corresponding receptor areas of the neuronal membrane and cause the transmission of information from neuron to neuron or effector cell. The mechanisms of these two processes are similar because in both cases mediators cause a change in ion permeability in the membrane. However, the change in the potential of the subsynaptic membrane in the case of the excitation process is due to changes in the permeability of sodium ions, while the inhibition process is associated with changes in the permeability of ions of potassium, chlorine, or both [1] [2].

Coordinated interaction of excitatory and inhibitory potentials contributes to the equilibrium of these processes. Various changes in pre- and postsynaptic mechanisms can lead to an imbalance between excitation and inhibition and switching to an abnormal mode of action, which occurs in some neurological and mental illnesses, and the most obvious example of this is epilepsy [1] [3].

According to most researchers, in the process of excitation-inhibition, the inhibitory function of the CNS is performed by GABA-amino acid (GABA), glycine and taurine, while the excitatory function is associated with glutamine and asparagine acids. The main energy source of neuronal activity is glucose. As a result of anaerobic and aerobic conversions of glucose, ATP is synthesized, which is the energy basis of active processes in the nervous system. Glycolysis takes place in the cytoplasm, resulting in 2 molecules of adenosine triphosphate (ATP) and pyruvate, instead of 1 molecule of glucose [2] [4].

Changes in glucose metabolism deficiency in the action of Na⁺/K⁺-ATPasa, as mentioned above, are associated with neuronal hyperactivity. This is one of the leading mechanisms of reducing the concentration of extracellular K⁺ accumulated after convulsive activity [5].

Observations on numerous clinical and experimental studies have revealed the pathogenetic role of oxidative stress. Epileptic seizures occur against the background of oxidative stress and hypermetabolic state, which we also mentioned in this article [6] [7], all this is done in the context of oxygen-generated activity. Seizures increase blood flow to the brain, thus increasing the need for oxygen and glucose, causing the blood vessels to dilate and blood pressure to rise, leading to the formation of nitric oxide and adenosine. Despite such a sudden increase in oxygen and glucose during the convulsive processes, the energy expenditure is so great that this energy balance in the brain is depleted very quickly and the hypermetabolic state in the period between seizures changes into a hypometabolic state. This is followed by impaired mitochondrial function and oxidative stress [8] [9].

What is the mechanism that explains the link between impaired glucose metabolism (often glucose hypometabolism) and epileptogenesis? Two hypotheses have been formulated on this issue: The first mechanism is based on the neurotransmitter, especially the gamma-amino acid (GABA) change in the system. The functioning of neurotransmitter systems requires quite a lot of energy. For GABA-ergic neurons, the gamma-aminobutyric acid uptake mechanism plays an important role in GABA resynthesis, whereas glutamatergic neurons are primarily dependent on glutamine as a precursor of glutamate derived from astrocytes. Accumulation of glutamate causes damage to glutamate receptors, activation of Na⁺ and Ca⁺⁺ channels, accumulation of Na⁺ and Ca⁺⁺ ions inside the cell, and accumulation of K⁺ ions in the cell fluid [10].

An important role in the theory of epileptogenesis is also given to the membrane theory: the trigger factor. The cause of neuronal epilepsy is a structural change in the neuronal membrane including the synapses, leading to inactivation of ion pumps and abnormal hyperactivity of ion channels. Changes in glucose metabolism deficiency in the action of Na⁺/K⁺-ATPase, which, as mentioned above, are associated with neuronal hyperactivity. This is one of the leading mechanisms to reduce the concentration of extracellular K⁺ accumulated after convulsive activity. Low Na⁺/K⁺ ATPase activity is associated with the development of epileptic seizures. In addition, Na⁺/K⁺ ATPase activity reduces within a few minutes after transient focal ischemia in rat cortex and hippocampus and in an experimental model of brain trauma. Altered ion homeostasis may also partially explain the interaction between convulsive activity and hypoglycemia [3]. Due to the above, changes in glucose metabolism deficiency during oxidative stress and disruption of ongoing processes involving NA⁺-K⁺ ATPase may be considered as one of the reasons for the development of epilepsy [11].

Nitric oxide (NO) plays an important role in the peripheral microcirculation and activation of central hemodynamic processes, as well as in the regulation of ion exchange of Na⁺ K⁺ and Ca⁺. Activation of nitric oxide (NO) and the formation of hydrogen peroxidase (H₂O₂) occur during various reactions, one of which is exposure to small doses of radiation (hormesis) when the presence of (H₂O₂) stimulates the production of excess NO in microphages. Because of this, NO can be considered in the context of an autocrine homeostatic modulator [12].

Small doses of radiation have long been used in medicine to treat various diseases. We want to focus on the change in excitation-retention reactions under radioactive gas radon in the natural environment during epilepsy [6].

This study was based on our research of the effects of radon inhalation on aggressive rats. It was found that after 5 minutes of inhalation daily for 7 days, aggressive rats lost aggressiveness and became non-aggressive and their noradrenaline level increased. [13]. It should be noted that these changes occurred 1 month after the end of inhalation procedures and the effect lasted for 6 months, which suggests that the process is not carried out by direct chemical reactions, but by the activation of ongoing processes by strengthening the body’s immune system.

Radon is a radioactive gaseous element that has mainly alpha radiation and is actively used in cases of age-induced brain disorders and hypertension [9]. Another well-known positive effect of radon baths is the intensification of the action of such perfusing agents as increasing the level of adrenaline in the blood plasma [14] [15] [16].

Based on all the above, the main goal of the study is to investigate the effect of Tskaltubo radon-containing water inhalation on the development/course of convulsive reactions in experimental animal models of epilepsy in particular, the change in the antioxidant processes in the body and the change in the concentration of Na-K ATP [17] [18] [19]. Genetically seizure-determined Krushinsky-Molodkina (KM) rats were placed in the audiogenic stimulation chamber [20]. The chamber represented the Plexiglas box of 60 × 60 × 60 cm³ with standard call on upper part of the box. A high pitch sound stimulus was presented to rats (110 dB, during 60 s) in response to which they developed seizure reactions [12]. Motor components of seizure activity were estimated by a slightly modified [17] scale: 0-fear reaction; 1-facial muscle clonus; 2-head tremble, jaw myoclonus; 3-wild running reaction, forepaw myoclonus; 4-myoclonus of fore- and hindpaws, fall on the side; 5-clonus of the four paws, skeletal muscle rigidity, ataxia, asphyxia [15] [18]

Animals: For our experiment, we used 24 months Krushinsky-Molodkina (KM) line male rats. They are predisposed to audiogenic epilepsy (seizures in response to a strong sound). Rapid (5 - 7 sec.) development of clonic-tonic seizures and the development of postictal catalepsy are characteristic of KM rats [8]

Epileptic seizures: For induction of epileptic seizures, we used an audiogenic signal before the study to which the experimental animal responded with cramps. In particular, the trigger caused the development of myoclonic seizures with “limbic” localization. Long-term (15 min) exposure of KM rats to the action of sound according to a special scheme with alternating 10 s periods of strong and weak sound causes cerebral circulation disorders in them, externally manifested in the form of paresis and paralysis of the limbs [12]. On the 5th day’s assessment of epileptic seizure with trigger-sound in BK rats was performed.

Radon measurement: in Tskaltubo spa center, were natural mineral water is used, we measured Radon’s radioactivity in water. The radioactivity of Radon was 37 becquerel (bk) in 1 m³ (37 bk/m³).

Radon inhalations procedure: we placed 10 experimental animals (KM rats) in Tskaltubo mineral water spa’s sauna (experimental group). Mineral water temperature was 36˚C, Humidity 90%. Control group 10 KM rats was placed in another spa center’s sauna, were 36˚C mineral water (without radon) was delivered via inhalation. Humidity in this spa center’s experimental room was 90%. None (experimental and control group of rats) of the animals took a bath, they were just in two different saunas and living in the same conditions. Inhalation was taken through the nose, for minutes, once a day, in conditions of high humidity (about 90%) during 3, 5 and 10 days. After each procedure of inhalation, the rats were placed in a vivarium and given food and water.

Laboratory examination:

To study the physiological changes caused by inhalation of Tskaltubo water on oxidative level, which prevents the development of brain disorders associated with peroxidation reactions, we measured the free radicals concentrations (d-ROM)—reactive oxygen metabolites in the blood plasma of rats, using a photometric test, measured the concentration of hydroperoxides (ROOH) in the brain tissue, which gives us a pro-oxidant status of the tissue. Hydroperoxides, also called Reactive Oxygen Metabolites (ROM), are formed during an oxidative attack when Reactive Oxygen Species (ROS) react with various organic substrates (e.g. carbohydrates, lipids, amino acids, proteins, nucleotides, etc.).

To assess the antioxidant capacity of plasma, we used the PAT (Antioxidant Concentration Test) by measuring ferric reducing ability and to evaluate the effectiveness of antioxidants, we determined the OSI (Oxidative Stress Index) and the OBRI (Oxidation Balance Status).

All named measurements were provided by means of Photometric Analytical System FRAS5 (H&D, Parma, Italy) [19].

Cysteine thiols and their oxidized disulfide counterparts are carefully balanced to maintain redox homeostasis in various cellular compartments, protect organisms from oxidative and xenobiotic stressors and partake actively in redox-regulatory and signaling processes. In this review, we will discuss the role of protein thiols as scavengers of hydrogen peroxide in antioxidant enzymes, use thiol peroxidases to exemplify how protein non-protein thiols group thiols contribute to redox signaling, provide an overview over the diverse set of low molecular weight thiol-based redox systems found in biology, and illustrate how thiol-based redox systems have evolved not only to protect against but to take full advantage of a world full of molecular oxygen [21] [22]. Determination by ELISA kit.

Data processing algorithms and statistical procedures. Modern multidimensional and multiparametric statistical methods such as dispersion analysis (MANOVA) were used for the complex processing-generalization of the obtained experimental material. STATISTICA-7.

Epileptic seizure:

From the data presented in Figure 1 and Table 1 we can see the following: On the 5th and 10th days after inhalation of low doses (37 Bq/m³) (Table 1 and Figure 1), the latent period of inhalation of radon before attacks and the pauses between attacks significantly increased (p < 0.05) in the group of radon irradiation, compared to control. The latency period before inhalation of radon in rats with epilepsy was (11 ± 1.1), and on the 5th and 10th days after inhalation of Tskhaltubo randomized water, the latency period increased to 16 ± 1.4 and (18 ± 1.3) seconds, respectively. The duration of the first and second jumps after the trigger was reduced in the group of rats receiving radon inhalation (p < 0.05). In all groups, the wild run began immediately after receiving a sound signal (call), but the duration of the first wild run decreased from (10 ± 1.1) sec (control group) to 3 ± 0.1 sec on the fifth day after inhalation of radon and even longer by tenths the day after inhalation with radon was reduced to (1.5 ± 0.1) sec.

After receiving a sound signal, the duration of the second run decreased from (58 ± 1.7) seconds to (39 ± 1.1) seconds on the 5th day after inhalation and (35 ± 1.1) seconds on the 10th day after inhalation. The duration of generalized audiogenic tonic-clonic seizures in the radon inhalation group on day 5 after inhalation

was (52 ± 1.3) seconds. As can be seen from the table, on day 10 after inhalation—(2 ± 0.1) seconds, the effect of radon causes an increase in the latency period for 5 and 10 days after inhalation.

From the data presented in Table 2 we can see the following. Study of dROM in genetically epileptic Molotkin’s Krushinsky rats before exposure to radon showed very high oxidation status (521 ± 3.67), and on the 5th day after exposure to radon the level of oxidative stress was (381 ± 2.95), which is statistically significant (p < 0.05). The hematological concentration of antioxidants (PAT plasma with antioxidant fragments) was at the edge before being taken to Tskaltubo in epileptic rats (2091 ± 3.95), and as a result of inhalation of radon became (2763 ± 0.85)—statistically it is reliable (p < 0.05). OBRI (Oxidation Balance Risk

Index): if it was before radon inhalation (1.95 ± 0.3)—dangerously high for the organism, after inhalation it was recorded as high, but this data was not dangerous for the organism (1.6 ± 0.2). The difference between them is statistically significant as well (p < 0.05). OSI—The correlation of total oxidative status with the total antioxidant status used to determine the Global Redox status index in epileptic rats was (142 ± 2.3) before radon inhalation, above the critical situation, and after inhalation it was halved to (111 ± 2.3) (Figure 2, Table 2).

As for the 10th day after radon inhalation, all oxidative stress relievers approached the norm. From the above mentioned we can conclude that a positive result was obtained when inhaling radon.

Oxidative stress plays an important role in biology of epilepsy. Sulf groups act like antioxidants and break chain of oxygen-derived free radicals. Measurements of serum thiol (Sulfhydryl group—SH), oxidative stress markers, which prevents the development of brain disorders associated with peroxidation reactions, Also used to evaluate the antioxidant status in case of epilepsy. As it is known from the literature, in case of disturbance of homeostasis caused by oxidative stress, the body tries to restore the disturbed homeostasis and activate the antioxidant systems by activating antioxidant systems, including Sulfhydryl groups. [7] [23]. Therefore, we studied SH divided into protein thiols (PSH) and non-protein thiols (NPSH) on the 5th and 10th days after radon inhalation, since on the 10th day, the redox status was on the verge and it would be interesting to study sulfhydryl groups on the 5th - 10 today.

Definition of sulfhydryl groups:

It is known from the literature that protein cysteine thiols respond to the cellular redox state. They can oxidize and inhibit thiol-proteins and enzymes and therefore have antioxidant action. In particular, when oxidants increase in the cell, thiol-disulfide is involved in redox regulation. These redox-sensitive mechanisms are involved in redox various changes including cell hypoxia. Under hypoxic conditions, the concentration of thiols decreases. This is due to the association of metabolites produced during the recovery of hypoxia with glutathione

(GSH), cellular nonprotein thiols (NPSH). That is, the metabolites react with GSH instead of oxygen. When cellular thiols are depleted, peroxide is produced [7] [23] and excessive oxidative stress leads to cell death. Within the frames of our study, we examined the quantitative variation of non-protein and total Sulfhydryl groups [11] [16]. To do this, on the 5th and 10th day after the end of the radon inhalation procedures, we determined the concentration of non-protein and total SH groups in the rat brain (Figure 3, Table 3).

Note: **P < 0.05. n = 28 (14 in each group).

In the case of non-protein sulfhydryl groups, on the 5th day (control 1.03 ± 0.123), it increased compared to the control and became (1.25 ± 0.105**), while on the 10th day it became 1.70 ± 0.109**. As for the total sulfhydryl groups, the concentration on the 5th day (control 33.00 ± 1.22) decreased compared to the control and became (27.56 ± 1.41**) and on the 10th day compared to the control increased statistically and became (37.16 ± 1.44**) (control 33.00 ± 1.22) respectively. Total sulfhydryl groups also had higher concentrations on the 10th day after radon inhalation compared to the control group (37.16 ± 1.44) and (1.70 ± 0.109), respectively, indicating an increase in the concentration of protein and total sulfhydryl groups on the 10th day compared to controls, than compared to the group performing inhalation with conventional mineral water. We see the effect of radon inhalation on physiological processes, which acts as an activator or inhibitor of some neurotransmitters [24].

In view of all the above, it can be said that radon exposure regulates oxidative stress, the clinical manifestation of which may manifest as a reduction in epileptic seizures, as evidenced by trials. Considering that audiogenic epileptic seizures begin immediately after the call and last for minutes before inhalation of Tskaltubo in experimental rats, as shown in Figure 3, the duration of epileptic seizures does not exceed 2 seconds after inhalation of Tskaltubo water, and it was also manifested without audiogenic seizures, it is known that this enzyme, which is active in animals, consumes a large amount of ATP. Changes in glucose metabolism deficiency in the action of Na⁺/K⁺-ATPase are associated with neuronal hyperactivity. This is one of the leading mechanisms to reduce the concentration of extracellular K⁺ accumulated after convulsive activity. Low Na⁺/K⁺ ATPase activity is associated with the development of epileptic seizures. In addition, Na⁺/K⁺ ATPase activity was reduced within a few minutes after transient focal ischemia in rat cortex and hippocampus and in an experimental model of brain trauma. Altered ion homeostasis may also partially explain the interaction between convulsive activity and hypoglycemia [5] [6] [7] [8]. As can be seen from Table 4, on the 10th day after inhalation there is an increase in Na⁺/K⁺ ATP-ase. It is important for reducing epileptic seizures and in some cases for disappearing, which was shown in our previous experiments on the 3rd day after inhalation of Tskaltubo radon-containing water [13]. In the following experiments we studied Na⁺/K⁺ ATPase activity on the 5th or 10th day after radon inhalation and as the graph shows the 5th day Na, K⁺-ATP-activity was (8.57 ± 0.10 mmol pi/mgE.houx), And on the 10th day the activity increased by 72%, (but compared with the 5th day it increases by 174% amounted to 14.89 ± 0.19), which again shows that on the 10th day after radon inhalation in Tskaltubo there is a reduction in oxidative stress and stays within the norm.

Na⁺/K⁺ ATPase activity is manifested in a decrease in first and second wild jogs in animals, including an increase in pause and a decrease in tonic-clonic seizures, and on day 10 it is very Decreased and remained within (2 ± 1.1) seconds.

Thus, numerous experimental data and individual clinical observations indicate the pathogenic role of OS in epilepsy, which is associated with disruption of the structural, hematoencephalic barrier integrity of has also occurred in the results of our study. According to our research, the use of radon inhalation in experimental animals, particularly in genetically determined rats with epileptic seizures, altered all parameters of the cell membrane of neurons, oxidative destruction of nucleic acids and radon exposure regulates oxidative stress, the clinical manifestation of which may be expressed by a reduction in epileptic seizures, and which of the epileptic seizure development Figure 1, namely the hidden period, the first and second wild jog duration after the audiogenic signal. All mentioned suggest that radon inhalation could be used to treat epilepsy. Excretion of excitatory amino acids (mainly glutamate) is known to increase during seizures. At this time, neuronal activity increases and intracellular calcium levels increase, which is associated with the formation of ROS [20]. Disruption of calcium

metabolism is associated with a sharp increase in cell cytosol and leads to the activation of Ca⁺⁺ dependent enzymes. The formation of ROS is accompanied by the synthesis of prostaglandins from arachidonic acid. This in turn enhances free radical reactions that ultimately lead to membrane destruction (Figure 4, Table 4).

Thus, numerous experimental data and individual clinical observations indicate the pathogenic role of OS in epilepsy, which is associated with disruption of the structural, hemato-encephalic barrier integrity of the cell membrane of neurons, oxidative destruction of nucleic acids and radon exposure regulates oxidative stress, the clinical manifestation of which may be expressed by a reduction in epileptic seizures, and which has also occurred in the results of our study. According to our research, the use of radon inhalation in experimental animals, particularly in genetically determined rats with epileptic seizures, altered all parameters of the epileptic seizure development picture, namely the hidden period, the first and second wild jog duration after the audiogenic signal. All mentioned suggest that radon inhalation could be used to treat epilepsy. Based on the obtained data, we can conclude that: Inhalation of Tskaltubo water 37 bk or 1 nk—develops the effect of Hormesis, which causes positive changes in all the above oxidative stress markers in the brain, as shown by the data we have studied. Based on the given data, inhalation of Tskaltubo water can be considered as one of the methods of removing the convulsive effects and its treatment, which is confirmed by experimental studies.

The data of this study indicate that the effect of radon hormesis (R-Ho) happens by the activation of NO and formation of hydrogen peroxide (H₂O₂) that activate excessive NO production in microphages under the effect of interferon gamma and beta (INF-γβ) [25] [26]. As a result the increased production of NO activates peripheral microcirculation and central hemodynamic. In this reason NO can be considered as an autocrinic homeostatic modulator as well [17] [18].

It is established that macrophage-killers are the important source of NO. By NO activation they suppress DNA synthesis of tumor cells and suppression of new tumor cells, anti-inflammatory, desensibility and sedative mechanisms. NO effects on activation of DOFA, DOFA-cines and DOFA-amino formation in blood; it is involved in regulation of the Na⁺, K⁺ and Ca⁺⁺ ion changes, and play one of the main roles in suppression of specific autoimmune and in activation of non-specific immune systems of the body [5] [8].

In our case the reduction in oxidative stress is seen as early as the 5th day after exposure to radon inhalation due to NO activation, NO can be considered as an important neurotransmitter that can participate in synaptic transmission as classical, from presynaptic to postsynaptic neuron [9] [14] [18] [24] [27] and retrograde, also indirectly by acting on glial cells or surrounding neurons. NO protects the brain from ischemic and neurotoxic stroke, controls the oscillatory activity of neurons [11] [17] [27], nitric oxide synthesis is often considered as a protective mechanism against the cytotoxic action of phagocytes, since NO inhibits the activation of the neutrophil [19] and NADPH oxidase activity, reduces xanthine oxidase activity, decreases AFK products [10]. At the same time, it should be noted that NO is involved in the development of the inflammatory process and its effect on the functional state of phagocytes can be modulated and changed over time. Therefore, the protective or cytotoxic action of NO is also characteristic of certain cells and tissues. Experimental models of epilepsy show that increased oxidative stress (increased oxidation of lipids and proteins) is accompanied by the development of seizures [21] [28].

Studies by E. Ben-Menachem (2000) have shown that erythrocyte SOD1 activity is significantly lower in patients with progressive myoclonic epilepsy than in healthy individuals. Decreased SOD1 activity also occurs in the cerebrospinal fluid of patients with epilepsy, especially in the disease-resistant group compared with patients with curable forms of epilepsy and in the control group of healthy individuals. The authors believe that decreased SOD1 activity is associated with recurrent seizures, and that SOD1 deficiency in cerebrospinal fluid may be a predictor of drug-resistant epilepsy [29].

In addition to the above, the convulsive state is characterized by anomalous Na⁺ and K⁺ metabolism. Accumulation of ammonia also occurs at this time, which is associated with the intensification of deamination reactions; all of this leads to depolarization of cell membrane shells, lowering of the excitability threshold, and a new series of seizures. In the first minutes of seizures, neurotransmitters are released, accompanied by a change in the level of secondary messengers, which is reflected in the activity of metabotropic receptors. And on the 5th and 10th day after radon inhalation activation of adrenoceptors causes an increase in cyclic adenosine monophosphate. Inhalation of radon as we have shown in a previous publication, reduces the number duration of behavioral seizures and in some cases makes them disappear [20].

Excretion of excitatory amino acids (mainly glutamate) is known to increase during seizures. At this time, neuronal activity increases and intracellular calcium levels increase, which is associated with the formation of ROS [2] [20] [30]. Disruption of calcium metabolism is associated with a sharp increase in cell cytosol and leads to the activation of Ca⁺⁺-dependent enzymes. The formation of ROS is accompanied by the synthesis of prostaglandins from arachidonic acid. This in turn enhances free radical reactions that ultimately lead to membrane destruction [6] [22] [29].

Thus, numerous experimental data and individual clinical observations indicate the pathogenic role of OS in epilepsy, which is associated with disruption of the structural, hematoencephalic barrier integrity of the cell membrane of neurons, oxidative destruction of nucleic acids and radon exposure regulates oxidative stress, the clinical manifestation of which may be expressed by a reduction in epileptic seizures, and which has also occurred in the results of our study [16] [23].

According to our research, the use of radon inhalation in experimental animals, particularly in genetically determined rats with epileptic seizures, altered all parameters of the epileptic seizure development picture, namely the hidden period, the first and second wild jog duration after the audiogenic signal. On the third day, no response to the audiogenic signal was observed at all, and not even a single episode of tonic-clonic seizures. All mentioned suggest that radon inhalation could be used to treat epilepsy [1] [6].

According to the International Classification of Epileptic Seizures, we are talking about focal seizures and in our experiment, the effectiveness of Tskaltubo water has been confirmed in the case of focal epileptic seizures. As for generalized epilepsy, the impact of radon hormone on these types of seizures is still unclear, which requires additional scientific studies [8].

The impact of radon inhalation on seizures of brainstem epilepsy models is particularly important because mechanisms of prolonged bilateral (formerly generalized) seizures in humans are considered to be erased/included in brainstem structures [5] [28].

Presented study is the first precedent of attempt R-Ho through inhalation for treatment of epileptic seizures in animal models with further translation to clinical study in humans through pilot phase II study. More profound and scientifically systematized approach is needed to determine uniqueness of Tskhaltubo water springs, investigation the mechanisms of radon effects on the excitatory and inhibitory functioning of CNS and further clinical studies to establish its effect on humans [27] [28].

To clarify the mechanism of radon’s action on antioxidative processes, future research is required, but based on the results of the experiment we can conclude that:

Studies in experimental animals have shown that inhalation of Tskaltubo water develops hormesis that regulates oxidative processes in the brain by activating antioxidants, which is reflected in the reduction of existing epileptic convulsions and is reflected in the activation of Na/K ATPase.

Inhalation of Tskaltubo water may be considered as a method of treatment with anticonvulsant effect confirmed by experimental studies.
