The purpose of the study. To study the effect of Mexol's drug on the level of factors regulating neurogenesis.

Material and methods. The study is performed on Wistar rats. Focal cerebral ischemia was reproduced by endovascular occlusion-repertension of the right middle brain artery according to the J. Koizumi method (1986). The duration of occlusion was 60 minutes. During the start of reperfusion of animals, saline or Mexidol at a dose of 50 mg/kg were once introduced once intravenously. After 4, 8 hours and 24 hours after the start of reperfusion in the ischemic hemisphere, the relative number of molecules regulating neurogenesis was estimated by Western-Blot. Additionally, 24 hours after the start of reperfusion, the size of the cerebral infarction was analyzed after painting with a 1% solution of 2.3.5, -rypheniltetrazoli.

Results. When modeling occlusion-reperture of the medium brain artery, the volume of necrosis in the affected hemisphere of animals, which was introduced by the physiological solution, was 37.75 ± 7.46%, the administration of Mexidol at a dose of 50 mg/kg led to a decrease in necrosis to 20.48 ± 2.33% (p = 0,0006). Modeling Occlusion-Reperterposition of the middle cerebral artery was accompanied by the activation of neurotrophic factors IGF-1, NGF and vascular factor of VEGF. A single intravenous administration of Mexidol at a dose of 50 mg/kg during reperfusion was accompanied by a more significant increase
in the level of neurotrophic factors IGF-1, NGF, BDNF and VEGF in the ischemized area of ​​the brain compared to the introduction of saline, which leads to an increase in neuro-regeneration for all surveillance periods (4, 8 hours and 24 hours and 24 hours and 24 hours and 24 hours and 24 hours and 24 hours and 24 hours and 24 hours and 24 hours and 24 hours After reperfusion), the marker of which is tubulin-3.

Conclusion. The results indicate that Mexidol not only has a protective effect on neurons, but can also stimulate neuroregeneration, increasing the level of basic regulatory molecules.

Keywords: Mexidol, ethylmethylhydroxypirinate, acute cerebrovascular disorders, neurogenesis, hematoencephalic barrier.

The purpose of the study.

The study of the influence of Mexidol on the dynamics of rats of rats after light or dark deprivation on the swimming dough model with load, as well as an assessment of the state of glycolytic processes in these conditions. Material and methods. The experiment was performed in the spring on 70 rats of the Wistar line. Three groups (30 animals) were in the natural conditions of lighting. One group was not exposed to any influences. Two other groups were presented with physical activity and 30 minutes before it was administered intramuscularly either a physiological solution or Mexidol. Four other groups (40 individuals) 10 days were in the conditions of dark or light deprivation before the presentation of physical activity and received either a physiological solution or Mexidol before the test after the abolition of deprivation.

Summary:
Purpose of the study. To study the effect of ethyl-hydroxypyridine of the succinate (EMGPS) on the anti-Bolar effect of the non-election inhibitor of cyclooxygenase (COO) of the sodium diclofenac and selective chief-2 ethrioxib inhibitor on the models of acute visceral and somatic pain and evaluate the possibility of using EMGPS in combination with the inhibitors of the TSU for the reduction their doses with the preservation of anti -Bolar efficiency . Material and methods. The effect of EMGPS was studied with a single oral effect on anti-Bolar effects of non-steroidal anti-inflammatory drugs (NSAIDs): a non-melting inhibitor of the diclofenac sodium and selective TSOG-2-2 etrica inhibitor-on the models of acute visceral (vinegar croching test) and somatic pains (formalin tests the one Hyperalgesia with inflammation) in an experiment on mice and rats. Results. On the model of acute visceral pain in EMGPS mice (25–100 mg/kg) does not have a significant effect on its severity, but enhances the anti -Bolea effect of sodium diclofenac (0.5 mg/kg) and ethricoxib (1 mg/kg). In the formalin test in rats that simulates pain during operational cuts (injury), EMGPS (25 mg/kg) increases the severity of the anti -folly action of TSOG inhibitors (1 mg/kg) primarily due to a decrease in pain in the acute phase, due to the effect of formalin on afferent neurons . On the model of mechanical hyperalgesia in rats caused by exudative inflammation after injection of the Karraginan solution in the paw, the EMGPS enhances the effect of diclofenac to a greater extent than ethricoxib. Conclusion. The data obtained indicate the appropriateness of clinical study of the use of EMGPS in combination with NSAIDs for visceral and somatic pain in order to evaluate its ability to increase the therapeutic effect of NSAIDs. Keywords: ethylmethylhydroxypyridine succinate, non -steroidal anti -inflammatory drugs, visceral pain, somatic pain, mouse, rats.

Summary:
Purpose of the study. The study of the role of oxidative stress in the development of disorders that occur with hemorrhagic stroke (GI), and the assessment of the influence of Mexidol on neurological and cognitive disorders with the analysis of the relationship of therapeutic effects of the drug with its antioxidant effect. Material and methods. The study was carried out on sexually mature out-and-aids weighing 260–280 g. The Gi model was created by destruction of brain tissue in the Capsula Interna with the introduction of blood damage to the place. On the 1st, 7th and 14th day after the modeling of GI in rats, death, neurological deficit (McGrow scale, a rotating rod, TVS), convulsive syndrome, violation of cognitive functions were recorded, a quantitative analysis of the indicators of oxidative stress with the assessment of TBK-active (thiobarbituric acid - TBK) products in blood plasma and homogenates of the cortex of the brain of rats. Mexidol was introduced after surgery in the first 3 days at a dose of 150 mg/kg intra-abdominal, then (from 4 to 14 days)-75 mg/kg inward. Results. Mexol in rats with GI significantly increases survival, reduces the severity of the neurological deficit on the McGROW scale (manners, paresis of 1-4 limbs, paralysis of the lower extremities, lateral position), eliminates convulsive attacks, restores violation of movement coordination (TVS) and improves training processes and improves training processes and improves learning processes and improves memory. Mexidol normalizes the concentrations of TBK-active products in the blood of animals and homogenes of the cortex of the brain of rats 1 and 7 days after the GI. Conclusion. The data obtained indicate the role of oxidative stress in the development of violations with the GI and the ability of Mexidol to weaken the neurological deficit, convulsive manifestations and cognitive disorders for GI, which limits the manifestations of oxidative stress. All this substantiates the significance of the use of Mexidol in patients with GI and determines the features of its therapeutic effects. Key words: hemorrhagic stroke, intracerebral hematoma, oxidative stress, Mexidol, neurological deficit, convulsions, cognitive disorders.

Resume

The purpose of the study . Studying the ability of the drug Mexidol to induce cerebral mitochondriogenesis in the brain of young and aging rats.
Material and methods. In the cerebral cortex of young (3 months; n = 216) and aging (6, 9, 12 and 15 months; n = 168), outbred rats by Western-Blot Analysis, the level of expression of cerebral mitochondriogenesis protein-markers with course use of Mexidol (20, 40, 100 mg/kg; 20 days; intra-abdominal).
Results. For the first time, it was shown that the exchange rate of Mexidol in doses of 40 and 100 mg/kg is accompanied by a dose-dependent induction of SUCNR1 sucnr1 and mitochondrial biogenesis proteins: PGC-1α transcriptional coactivator, transcription factors (NRF1, TFAM), catalytic subunits of respiratory enzymes (NDUFV2, SDHA, CYT B, COX2) and ATP-syntase (ATP5A) in the cerebral cortex of outbred rats of young and aging age. Mexol-dependent oven-sequences of subunits of mitochondrial enzymes and PGC-1α are noted only with the course use of the drug.
Conclusion. The data obtained indicate the ability of Mexidol to induce cerebral mitochondriogenesis and eliminate mitochondrial dysfunction in young and aging animals and, thus, influence one of the key pathogenetic links in the development of disorders during aging and neurodegenerative diseases.

Summary:
Purpose of the study. Studying the influence of Mexidol on cognitive and motor functions disturbed during aging, the threshold of convulsive reaction, body weight and life expectancy in the old rat smams of the Vistar line. Material and methods. In a long experiment, a violation of cognitive functions (a test of conditional reflex of passive avoidance), motor disorders (tests of a rotating rod and pulling on the crossbar), a convulsive threshold (a test of subcutaneous administration of the pentilentetrazole), an animal mass and life expectancy were evaluated in a long experiment. Mexidol in the form of a 0.15% solution that replaced drinking water, rats received 2 courses of 2 months: at the age of 18-20 and 22-24 months. The dose of Mexidol consumed by the rat was 40–75 mg/kg/day. Results. Mexol in the old rat smams of the Vistar line with prolonged course use improves training, preservation and reproduction of a memorable trace in the test of conditional reflex of passive avoidance, increases the convulsive threshold and improves muscle tone and coordination of movements disturbed during aging, and increases life expectancy. The use of Mexidol allows us to prevent a significant increase in body weight, characteristic of aging. Conclusion. Mexidol reduces the severity of the cognitive and neurological deficiency that occurs during aging in the rats of the Vistar line, increases the threshold of convulsive reaction and increases life expectancy, which is determined by its ability to influence mitochondrioogenesis and antioxidant properties. Keywords: aging, Mexidol, life expectancy, memory violation, neurological deficit, convulsive threshold.

Summary:
Purpose of the study. To study the influence of the original domestic drug Mexidol on the expression of the transcription factor NRF2 in the cores of the cells of the frontal cerebral cortex with one -way occlusion of the general carotid artery. Material and methods. The work was done on 64 sexually mature rats of the Vistar line. The expression of NRF2 was determined by the immunohymic method. Results and conclusion. A single intra -Brushyne administration of Mexidol per 1 kg of body weight of the animal and its course oral administration per 1 kg of mass 3 times a day for 14 days did not affect the expression of the NRF2 factor. Unilateral occlusion of the general carotid artery increased the expression of NRF2 after 4 hours and on the 5th day after modeling occlusion. The oral administration of 100 mg of Mexidol per 1 kg of mass 3 times a day for 14 days before and after modeling ischemia increased the expression of NRF2 after 4 hours and on the 12th day compared to the norm indicators, as well as after 4 hours and on the 12th A day compared with the values ​​of the control of occlusion. Thus, it was established that Mexidol increases the expression of NRF2 in the frontal cortex of the rats of rats not in normal conditions, but with unilateral occlusion of the general carotid artery. Keywords: Mexidol, NRF2, ethylmethylhydroxypyridine succinate, ischemia, occlusion of the general carotid artery.
