EXPERIMENTAL AND CLINICAL INVESTIGATIONS
Substance for investigation serve patient with locally-associated epilepsy (LAE), taking antiepileptic drugs — 151 men. From them — 73 patients with drug-resistant forms of the disease and 78 patients with control epileptic seizure. Spend monitoring indicators of EEG during sleep and wakefulness cycle. In the group of patients with drug-resistant forms LAE significantly detected more frequently epileptiform activity and increase index α-rhythm during sleep in comparison with period wakefulness.
On the original experimental model of autoimmune oophoritis the stages of formation and extent of destruction to structural elements of the ovary were studied, using histological and histochemical methods, the content antiovarian antibodies in the serum of experimental animals by enzyme immunoassay was determined. Autoimmune oophoritis is the step-wise character, with a gradual increase in the pathological process, which is manifested in the growth of mononuclear infiltration, restructuring steroid-producing structures, destruction of oocytes.
The aim of the investigation was studying vicasole’s effect on experimental oxalate nephrolithiasis.
Experimental nephrolithiasis was being modeled by using of 1% ethylenglycole’s solution as a drink for rats during 6 weeks. First group was control. In the second group since the third week was being administrated vicasole in dose 500 mkg/kg. Was being detected parameters of kidney’s function, markers enzymes activity and free oxygen’s radicals activity, was carried out morphological researches.
It was concluded that vicasole’s therapy reduce experimental oxalate nephrolithiasis
A peculiarity of the congenital syphilis of recent years is an increase of the number of cases of latent forms of the disease, marked with osteopathy. With the help of an examination of 50 children with early congenital syphilis, the following ultrasonic signs of a musculoskeletal system lesion were revealed: osteochondritis 90%, osteosclerosis 80%, and periostitis 30%.
The comparison of the nature of a musculoskeletal system lesion with serological data of the specific process activity showed that complex manifestations of lesions with periostitis being a component were of the greatest clinical significance.
The effect of nanosecond pulses of X-ray (pulse repetition rate of 8—22 pulses per second, dose 0,3—1,8 mR per pulse) on the functional activity of isolated mitochondria of mice liver. The effects of changing the rate of oxygen consumption by mitochondria in different metabolic states of Chance and the degree of coupling of oxidation and phosphorylation were investigated. That effect depends on the parameters of exposure.
The data of the comparative analysis of separate parameters of cell and humoral chains of immune response in patients suffering from pulmonary tuberculosis accompanied by eosinophilia has been presented in the article.
With involving contemporary immunological methods of research, it has been stated that tuberculosis infection in combination with eosinophilic blood reaction is accompanied by marked cytokine imbalance, characterized by increase in the concentration of IL-5 (mediator with anti-inflammatory activity) in blood serum against the background of low serum level of the key anti-tuberculosis cytokine — IFN-γ.
The research of unsaturated and saturated of fatty acids (UFAand SFA) in the erythrocytes in men and women with chronic ischemic heart disease was done by the method of a gas-liquid chromatography-mass spectrometry before and after simvastatin intake. Increase in the ratio of ω3 / ω6 FA at the expence of reducing of the rate of ω6 UFAwas revealed in men after treatment for 2 months which is the condition for the changing of type of synthesized eicosanoids. The decrease in the total content of ω6 and ω9 UFAled to the fall in the amount of the UFAin both sexes, despite of the heightened rate of amount of ω7 UFAin women. The treatment led to the increasing of saturated FA amount (SFA) and it led to the decrease of unsaturation index FA on the back of the reduction of nonsaturated fatty acids level (NFA). The results confirm the presence of lipid-lowering effect of Simvastatin, but there is a need for therapy, taking into account of the normalization of the exchange FA in patients with chronic coronary ischemic heart disease.
This study investigates the contractile activity of smooth muscle segments of guinea pig pulmonary artery by the method of mechanografy and morphological picture of lungs, airways and blood vessels of the pulmonary circulation under the influence of nanosized magnetite. It is shown that chronic inhalation intake of magnetite nanoparticles has a cytotoxic effect, leading to inflammatory changes in the airways, lung parenchyma and pulmonary vessels, as well as a change in contractile activity of the pulmonary artery by the action of neurotransmitters and mediators of exercising their functions under physiological conditions or produced during the inflammatory the process.
We have examined 36 liquidators (participants in emergency clean-up after the Chernobylnuclear accident) many years after the external γ-irradiation (on average (143.0 ± 14.0) mGy for (3.3 ± 0.8) months) and 13 workers of a typical research nuclear reactor, who were subject to chronic external γ-irradiation (on average (78.40 ± 12.21) mGy for (13.1 ± 2.2) years). The level of metabolites of lipid peroxidation (conjugated diene and triene conjugates of lipid hydroperoxides, TBA-reactive products) and the activity of catalase, superoxide dismutase, 5'-nucleotidase in blood serum were determined; changes in vessels of microcirculatory bloodstream (MCB) in skin-muscle bioptate were analyzed. Under the action of small doses of ionizing radiation, the oxidative disbalance and changes in activity of 5'-nucleotidase in blood serum сaccompanying the systematic inflammatory alteration of MCB vessels were found.
Latent inhibition phenomenon indexes the ability to ignore irrelevant stimuli. Disturbance of latent inhibition is registered in different psychiatric populations with pathology in the emotional and cognitive spheres. In our experiments latent inhibition was measured in a conditioned passive avoidance reaction in rats that previously received 0 or 20 conditioned stimuli exposures followed by foot shock. Latent inhibition was disrupted in high-anxiety rats and pathologically enhanced in low-anxiety rats. The effects of an agonist (muscimol) and an antagonist (biсuсulline) of GABAA receptors on the learning and latent inhibition in these rats were studied. In high-anxiety rats, muscimol (1 mg/kg) had no effect on learning but enhanced latent inhibition. Biсuсulline (1 mg/kg) enhanced both acquisition of the reflex and latent inhibition in low-anxiety rats. The present results show direct involvement of GABAA-receptors in process of attentional inhibition to irrelevant information.
This article presents the results of experimental research of nanostructured track membranes implantation as drainage for refractory glaucoma surgery. For nanostructuring of the membrane surface was applied a treatment by air plasma. Tissues reaction of rabbit’s eyes to drainage implantation was studied in the experiment in vivo. The histological research data demonstrate that the reaction of the inflammatory cells to drainage was minimal. After antiglaucomatous operation filtering blebs were split and plane and in all the cases resulted in a stable hypotensive effect.
Problem of diagnosis and treatment of patients with necrotizing pancreatitis is an urgent. So it is interesting to study the effectiveness of a multicomponent antihypoxant and antioxidant cytoflavin to reduce violations of the detoxifying properties of the liver in experimental pancreatitis and reduce the severity of pancreatic endotoxemia. Pancreatic modeled by introducing into the pancreas of autobile in a dose of 0,15 ml/kg. Cytoflavin was injected into animals of a comparison group in a dose 0,21 ml/kg in
5 minutes after the model of pancreatic necrosis. We determined the activity of enzymes: alanine transaminase, amylase, and gamma glutamyltransferase, the content of direct bilirubin, glucose, and urea. After modeling of pancreatic necrosis in two days, there are signs of acute liver failure, as evidenced by the differences in the studied parameters of blood and hepatic portal vein: increased alanine transaminase and gamma glutamyltransferase, the change in concentration of metabolic products, such as direct bilirubin and urea. In addition, decreased glucose levels. Introduction of cytoflavin approached the control values the basic biochemical parameters of liver function: decreased hyperenzymemia, exchange function of the liver was restored, which is probably due to antihypoxic, membrane and antioxidant effects of the drug.
Subjects of the study were 100 chronic abdominal pain syndrome inpatients assigned to subgroups of different level of significance of psychological factors for the development of pain syndrome, different self-assessed pain level (utilizing visual analog scale), and different type of attitude towards disease (by the Bekhterev Institute Personality Inventory). Character and psychodynamic specialties were assessed in the aforementioned subgroups following to assignment. Proved by clinical and psychometric methods diagnosis of somatoform pain disorder was used as an indicator of high importance of psychological determinants. Differences between subgroups were assessed by the kit of questionnaires (Beck Depression Inventory, Spielberger Anxiety Scales, Wasserman Social Frustration Inventory, TAS, MCMI-III) and projective tests (Luscher and Szondi tests). Interference between psychosomatic and demographic characteristics within the sample, and accuracy of assigning subjects to subgroups were discussed. Interpretation of the acquired data with implications for psychotherapists was offered.
Original method of nonneoplastic tracheoesophageal fistula disjunction using compression construction with shape memory has been developed. The experimental study was performed on mongrels with preliminarily made tracheoesophageal fistula. The technique consists of fistula covering with pedicle fat flap and following clipping by the construction. In all cases tracheoesophageal fistula was eliminated simply and reliably. Macro- and microscopic investigation of intervention area revealed, that continuity of typical epithelium of trachea and esophagus was regenerated by the 14 day after operation.
It is shown that the process of establishing the equilibrium concentration of ions is exponential. But very small value of exponent leads to the fact that the ion concentration practically does not change at all reasonable times the values of diffusion, the possible changes as it lies within the experimental error of measurement.

LITERATURE REVIEW
The absence of reliably functioning small-diameter vascular grafts for coronary artery bypass graft surgery remains one of the most important issues of cardiovascular surgery. Tissue-engineered grafts have to be characterized by highly hemocompatible, biomechanical and biocompatible properties, be quickly biodegradable and have non-toxic degradation products. This article presents polyhydroxyalkanoate and policaprolactone main characteristics and evaluates their potential use as polymers for producing vascular grafts. Biocompatibility, good physical and mechanical properties of these polymers and their better performance in copolymer scaffolds were demonstrated.

To improve the results of treatment of patients with cholelithiasis and its complications, the comparative analysis of the frequency, causes, and character of biliary dust damages at traditional cholecystectomy and laparoscopic cholecystectomy and the results of reconstructive and restorative operations has been carried out. Among 6013 operated patients, duct traumas were observed in 0.6% at traditional cholecystectomy and in 0.7% at laparoscopic cholecystectomy. Based on the analysis of 56 repeated operations, the optimal tactics of treatment depending on the level and character of duct damages was determined. Prophylactics consists, first of all, in the early and adequate surgical treatment of patients with cholelithiasis.
In 17-year cohort p1rospective study, the dynamics of arterial hypertension (AH) and arterial pressure (AP) levels has been examined as functions of the boy mass. The cohort included 630 men and 916 women aged from 20 to 59. The overweight was diagnosed at the Body Mass Index index no lower than 25 kg/m2.
In the primary research, the AH prevalence rate was 35,7% among overweighted people and 12,5% (р < 0,001) among people with normal weight. In the 17-year observation, the increase of the body mass up to overweight was accompanied by an increase in the AH rate and AP levels, while the decrease of the body mass down to the normal one was accompanied by a decrease of these indices (except only for men aged from 40 to 59). Among overweighted people revealed at the I and II stages of the study, the systolic ((155,71 ± 28,59) mmHg) and diastolic ((93,68 ± 13,77) mm Hg) AH was higher than that in people, who became overweighted the observation: (137,08 ± 23,02) and (86,73 ± 12,19) mm Hg, respectively (р < 0,001).
