Background.We studied the effect of combined application of omega-3 polyunsaturated fatty acid concentrate, based on seals fat, with parenteral administration of brain cortex polypeptide preparation on cognitive-research reactions and adaptation of rats under experimental hyperlipidemia. The composition of the myelin sheaths of neurons is represented by a protein-lipid complex, which is a part of the cell membrane, the imbalance of which leads to a number of neurological diseases.The aim of the study was to confirm experimentally that the combined use of drugs, based on essential polyunsaturated fatty acids and polypeptides, would influence more effectively on neurometabolic processes in neurons, compared to their application separately.Materials and methods.Wistar rats were used. They were on a special atherogenic diet to build the model of hypercholesterolemia. The pharmacological effects of drugs were evaluated in the Open Field and Morris Water Maze tests.Results.The study found that in rats, who received a combination of polyunsaturated fatty acids concentrate with Cortexin injections, and undergoing atherogenic diet, the overall motor activity increased significantly in the Open field test, at the same time the number of acts of defecation and grooming decreased. The Morris Water Maze test results indicated an increase in the level of spatial memory and orientation, which shows a high level of adaptability and adaptation to new conditions, a decrease in the level of anxiety.Conclusions.The results demonstrated a more pronounced and prolonged nootropic and adaptogenic action of the complex use in comparison with the use of the studied agents as monotherapy.

Background. Postoperative cognitive dysfunction (POCD) is a common complication after abdominal surgery. Several studies have reported that POCD is related to neuroinflammation caused by surgery. Omega-3 polyunsaturated fatty acids (PUFAs) can effectively inhibit the systematic inflammatory response. So, we use fish oil to study the effect of fish oil on inflammation, immunity, and cognitive behavior after splenectomy in rats. Methods. 60 SD (Sprague-Dawley) rats were randomly divided into control group (group C, n = 20 ), surgery group (group S, n = 20 ), and omega-3 (fish oil) intervention group (group F, n = 20 ). Omega-3 PUFA was injected intraperitoneally from 3 days before operation to 7 days after operation in group F, and normal saline was injected simultaneously in group S. Rats in group S and group F received splenectomy under general anesthesia. Morris water maze behavioral evaluation was performed on the first, third, fifth, and seventh day after operation. The levels of IL-1β (interleukin-1β), IL-6 (interleukin-6), TNF-α (tumor necrosis factor-α), SOD (superoxide dismutase), and GSH-PX (glutathione peroxidase) were detected. Results. Serums IL-1β, IL-6, and TNF-α concentrations in group S and group F were higher than those in group C ( P < 0.01 ), while those inflammatory cytokines in group F were significantly lower than those in group S ( P < 0.01 ); serum GSH-PX levels in group F were higher than group S ( P < 0.01 ). The Morris water maze behavior test performance of group F was better than that of group S ( P < 0.05 ). Conclusion. Omega-3 PUFA can effectively improve postoperative inflammatory response, reduce the damage of antioxidant defense system, and improve postoperative cognitive function.

Objectives. It  was to assess the degree of neurological deficit in rats with cerebral ischemia and administration of omega-3 polyunsaturated fatty acids. Methods. The experiments were carried out on 42 male outbred white rats weighing 260 ± 20 g. Modeling of cerebral ischemia was carried out under conditions of intravenous thiopental anesthesia (40-50 mg / kg). The studies used models of subtotal, partial and stepwise subtotal cerebral ischemia. The table shows the experimental groups and the number of animals in them. Subtotal cerebral ischemia (SCI) was modeled by simultaneous ligation of both common carotid arteries (CCA). Partial cerebral ischemia (PCI) was modeled by ligating one CCA on the right. Stepwise subtotal CI (SSCI) was performed by sequential ligation of both CCA with an interval of 1 day (subgroup 1), 3 days (subgroup 2), or 7 days (subgroup 3). To study the effects of omega-3 polyunsaturated fatty acids (ω-3 PUFA), animals with CI were injected intragastrically with the drug "Omegamed" (SCI+ω-3 PUFA) at a dose of 5 g / kg body weight for a week. The control group consisted of sham-operated rats of the same sex and weight. Neurological deficits were assessed in the "muscle strength", "swimming test" and "open field" tests after 5-6 hours of the ischemic period. Results. With a stepwise bilateral ligation of both common carotid arteries with an interval of 1 day, neurological disorders were most pronounced, which indicates an aggravation of neurological deficit with a reduction in the time between CCA dressings. In rats with SCI, the changes were more pronounced than with PCI, but less than with SCI. The least pronounced changes were noted in the 3rd subgroup (the interval between CCA dressings was 7 days). Studies have shown the dependence of the severity of brain damage in SSCI on the interval between the cessation of blood flow in both CCA. At a 7-day interval between CCA dressings, compensatory mechanisms were activated, which prevented the development of morphological changes and neurological deficits. When CCA was ligated with an interval of 1 day, the degree of neurological deficit was maximal, which indicates insufficient implementation of compensatory mechanisms. Compared with the control group, the rats of the "SCI+ω3-PUFA" group retained neurological deficit, the muscle strength indicator was 86% less (p<0.05), the swimming duration - by 63% (p<0.05), the number of crossed squares - by 55% (p<0.05), the number of washes - by 62% (p<0.05), the number of racks - by 62.5% (p<0.05) and the number of bowel movements - by 60% (p<0.05). However, in comparison with the SCI group, the neurological deficit was less pronounced. There was an increase in muscle strength by 67% (p<0.05), swimming duration by 37.5% (p<0.05) and the number of squares crossed in the open field test by 31% (p<0.05), which indicates the presence of a corrective action in the ω3-PUFA preparation. Conclusion. The introduction of the preparation of ω-3 polyunsaturated fatty acids has a corrective effect in conditions of subtotal cerebral ischemia, contributing to a lesser severity of manifestations of neurological deficit (an increase in muscle strength, duration of swimming and the number of squares crossed in the open field test).   Key words: cerebral ischemia, rats, neurological deficiency, omega-3 polyunsaturated fatty acids.

For the first time, we have studied the influence of polyunsaturated fatty acids on cholesterol metabolizing activity of bifidobacteria. High levels of destruction of cholesterol in the process of cultivation of strain Bifidobacterium Longum DK 100 was noted. Based on the results, the technology of probiotic dietary supplements (DS), enriched with polyunsaturated fatty acids, has been developed. The paper reveals that the introduction of probiotic DS leads to a twofold reduction in total cholesterol in the experimental groups in comparison with the control one, which indicates high effectiveness of DS. It has been observed that against the background of the atherogenic diet, the employment of probiotic DS is accompanied by a significant reduction in triglyceride levels by 37% and 45% in the "linen" and "cedar" groups, respectively, compared to the control group of animals. It has been established that in the blood serum of animals of experimental groups, the level of high-density lipoproteins increases by 45% in "linen" and 40% in "cedar" groups, while low-density lipoproteins decreased by 19% and 23% respectively. With the introduction of probiotic DS with linseed oil, the atherogenic index decreases by 83%, and with the cedar one by 86%. The results confirm the hypocholesterinemic effect of DS during cholesterol loading.

To study the effect of CGP 35348 on learning and memory in albino mice following hypoxia ischemia insult, 10 days old albino mice were subjected to right common carotid artery ligation followed by 8% hypoxia for 25 minutes. Following brain damage, mice were fed on normal rodent diet till they were 13 week old. At this time point, mice were divided into two groups. Group 1 received saline and group 2 intrapertoneally CGP 35348 (1 mg/mL solvent/Kg body weight) for 12 days. A battery of tests used to assess long term neurofunction (Morris water maze, Rota rod and open field) along with brain infarct measurement. Overall CGP 35348 has improved the motor function in male and female albino mice but effects were more pronounced in female albino mice. In open field, CGP 35348 treated female albino mice had demonstrated poor exploratory behavior. During Morris water maze test, gender specific effects were observed as CGP 35348 had improved spatial learning and memory and swimming speed in male albino mice but had no effect in female albino mice following hypoxia ischemia encephalopathy (HIE). We concluded that GABAB receptor antagonists CGP 35348 can be used to improve gender based spatial memory.

Objective. Omega–3 polyunsaturated fatty acids (PUFAs) were tested in adolescent depression and in several neurodevelopmental disorders with partial success. Anorexia nervosa (AN) is characterised by deficiencies in fatty food intake and frequent comorbidity, including depressive and cognitive symptoms. Thus supplementation with PUFAs may be beneficial in this group of patients. The aim of the study was to assess whether PUFAs as an add-on treatment is associated with better improvement of body mass index (BMI) and psychopathological symptoms than placebo in patients with AN. Method. 61 female adolescent inpatients with AN were randomly allocated to omega–3 PUFAs supplementation or placebo for 10 weeks. Patients also participated in the behavioural programme and eclectic psychotherapy (treatment as usual, TAU). At baseline and follow-up visits, patients’ BMI and psychopathology were assessed with Clinical Global Impression Scale (CGI), Patient Global Impression Scale (PGI), and Eating Attitude Test (EAT-26). Results. After 10 weeks, both groups showed improvement in all parameters. Improvement in CGI scores was observed greater in placebo vs. PUFA-s group (p = 0.015) while other differences were not statistically significant. Omega–3 PUFAs supplementation appears not to be effective as an add-on treatment in inpatient adolescent girls with anorexia nervosa. Conclusions. The results should be analysed with caution due to small sample size and heterogeneity in TAU. As the TAU turned out to be highly effective, additional therapeutic effect of PUFA might not be visible. Nevertheless, that does not explain the tendency for better improvement in the placebo group.
