Background & Objective: Aroclor 1254 is a widespread toxic compound of Polychlorinated Biphenyls (PCBs), which can create significant nervous problems. No remedies have been found to date. The aim of this study was to reveal the damage that occurs in the central nervous system of rat pups exposed to Aroclor 1254 in the prenatal period and to show the inhibiting effect of curcumin, which is a strong anti-oxidant and neuroprotective substance. Method: The study established 3 groups of adult female and male Wistar albino rats. The rats were mated within these groups and the offspring rats were evaluated within the group given Aroclor 1254 only (n=10) and the group was given both Aroclor 1254 and curcumin (n=10) and the control group (n=10). The groups were compared in respect of pathomorphological damage. The immunohistochemical evaluation was made of 8-hydroxdeoxyguanosine (8-OHdG), 4-hydroxynoneal (4HNE), myelin basic protein (MBP) expressions and TUNEL reaction. The biochemical evaluation was made of the changes in the TAS-TOS and Neuron Specific Enolase (NSE) levels. Damage was seen to have been reduced with curcumin in the 8OHdG and TUNEL reactions, especially in the forebrain and the midbrain, although the dosage applied did not significantly change TAS and TOS levels. Consequently, it was understood that Aroclor 1254 caused damage in the central nervous system of the pup in the prenatal period, and curcumin reduced these negative effects, particularly in the forebrain and the midbrain. Conclusion: It was concluded that curcumin could be a potential neuroprotective agent and would be more effective at higher doses.

To observe the effects of electroacupuncture on pain threshold of laboring rats and the expression of norepinephrine transporter andα2 adrenergic receptor in the central nervous system to determine the mechanism of the analgesic effect of labor. 120 pregnant rats were divided into 6 groups: a control group, 4 electroacupuncture groups, and a meperidine group. After interventions, the warm water tail-flick test was used to observe pain threshold. NE levels in serum, NET, andα2AR mRNA and protein expression levels in the central nervous system were measured. No difference in pain threshold was observed between the 6 groups before intervention. After intervention, increased pain thresholds were observed in all groups except the control group with a higher threshold seen in the electroacupuncture groups. Serum NE levels decreased in the electroacupuncture and MP groups. Increases in NET andα2AR expression in the cerebral cortex and decreases in enlarged segments of the spinal cord were seen. Acupuncture increases uptake of NE via cerebral NET and decreases its uptake by spinal NET. The levels ofα2AR are also increased and decreased, respectively, in both tissues. This results in a decrease in systemic NE levels and may be the mechanism for its analgesic effects.

Aim of the study was to identify the effects of myocardial revascularization on the prognosis in patients with altered coronary blood flow detected by transthoracic ultrasound.Material and Methods. Four hundred and twelve (412) patients were included in the study. The inclusion criterion was coronary velocity more than 70 cm/s during echocardiography. The study population was divided into three groups: Group 1 comprised patients with high velocities in the coronary arteries detected by ultrasound, in whom myocardial revascularization was performed; Group 2 comprised patients with high velocities in the coronary arteries, in whom myocardial revascularization was not performed and; the Control Group comprised patients with normal coronary blood flow according to ultrasound. The follow-up period was 10–11 months.Results. Seventeen (17) deaths (4.7%) occurred during follow-up. Death rates were 1.6 vs. 8.1 vs. 0% in Group 1, Group 2 and the Control Group, respectively, with a p-value for the difference between Group 1 and Group 2 (p1) of <0.009; and a p-value for the differences compared with the Control group (р2) of <0.03. Death, myocardial infarction, pulmonary edema, and acute coronary syndrome were observed in 27 patients (7.7% of the study group with accelerated blood flow). The rates of these outcomes were 4.9 vs. 11.0 vs. 0% in Group 1, Group 2, and the Control Group, respectively (p1<0.05; p2<0.006). Discussion. The study showed high rates of mortality or acute coronary events in the group of patients with pathologically high coronary flow velocities. The positive effects of revascularization on survival in this group were verified.Conclusions: 1. Left artery coronary flow velocities over 70 cm/s indicate a high probability of death or acute coronary events within 10.5 months.2. Myocardial revascularization has a significant positive effect on the survival rate and incidence of acute coronary events in patients with coronary artery flow velocities greater than 70 cm/s.3. Patients with high coronary blood flow velocities should be referred to coronary angiography or other diagnostic tests without waiting for clinical manifestations and specific symptoms for coronary artery disease.

Justification. Mental retardation is a persistent decrease in human cognitive activity against the background of organic damage to the central nervous system. Neurophysiological diagnostics, in particular electroencephalography (EEG), most adequately reflects the morpho-functional state of the central nervous system, which is the basis of the mechanisms of mental activity, and the originality of the bioelectrical activity of the brain can be considered as the main indicator that determines a decrease in the level of intellectual development and, thereby, characterizes this state. This provision actualizes the search for highly informative indicators of the originality of the bioelectrical activity of the brain in children with intellectual disabilities. Purspose. With the use of periodometric analysis investigate EEG’s indicators and interhemispheric asymmetry of rhythms amplitudes in MR patients. Materials and methods. The EEG was recorded in a state of calm wakefulness with closed eyes with Neuron-Spectrum-2 electroencephalograph. Differences in indicators were tracked using the calculation of the coefficient of compliance (CC), EEG functional asymmetry coefficients in amplitude were determined, too. Results. It was revealed that in MR patients the amplitudes of the rhythms were greater than in healthy subjects. The greatest increase was determined in theta rhythm in the anterior temporal and posterior temporal leads in the left hemispheres. Duration indices in the delta, theta and alpha ranges of the EEG in mental retardation compared with the control group were increased, and the indices of the duration of beta rhythms - decreased. When analyzing FMPA in MR persons it turned out that in right-handers the negativeness of FMPA indices increased, and in left-handers there was an increase in the positivity of FMPA indices. Conclusions 1. With mental retardation, the amplitudes of the rhythms were greater than in healthy people. The greatest increase was determined in theta rhythm in the anterior temporal and posterior temporal leads in the left hemispheres. 2. The indices of duration in the delta, theta and alpha ranges of the EEG of MR subjects were increased, and the indices of the duration of beta rhythms – decreased. 3. When analyzing FMPA in MR persons, it turned out that in right-handers the negativeness of FMPA indices increased, and in left-handers there was an increase in the positivity of FMPA indices.

The aim of the work is to study the level of systemic inflammation and changes in adaptive immunity in the early period after acute psychosis to assess their participation in the pathogenesis of alcoholic mental and cognitive disorders. We examined 28 patients with alcoholic psychosis (AP) and a control group of 17 healthy volunteers. Indicators of systemic inflammation and immunity, including key cytokines and lymphocyte subpopulations, were investigated. After acute psychosis of patients with alcoholism, pronounced activation of humoral immunity with impaired clearance of immune complexes, increased content and activity of Th2 with signs of insufficiency and dysfunction of Th1, reduced content and activity of cytotoxicity system cells and signs of systemic inflammation (increased CRP, cortisol, cytokines). Activation of Th2 response and an excess of proinflammatory mediators in patients with AP through various ways of interaction with the Central nervous system (n. vagus, choroidal plexus of the ventricles, and others) can participate in the disorders of metabolism of neurotransmitters in the Central nervous system involved in the pathogenesis of alcoholism, and in the maintenance of neuroinflammation. A high level of systemic inflammation can be both a trigger of psychosis and a manifestation of violations of neuroimmune interactions, as well as the development of excitotoxicity and damage to neurons in acute psychosis.

Multiple sclerosis is the most common demyelinating disease of the central nervous system, affecting mostly young people. There were many risk factors for MS identified, however a direct cause of the disease is still unknown. Pathological changes in the SM lead to the myelin sheath damage around axons, what prevents proper transmission of nerve impulses in the central nervous system. The aim of this study was analyzing and comparing the amino acids profile in the blood serum of MS patients to control group of healthy individuals and evaluating the relationship between them. Significant (p<0.05) differences in the level of glutamate, aspartate and taurine in the blood serum of MS patients were revealed. A positive glutamate and aspartate level correlation in the serum has been demonstrated. Gender is significant only in the case of glutamate level in blood serum. The studies highlight the important role of neurotransmitters in MS and are the initial step in proteomic research.

Labeling Pattern

Each astrocyte forms an extensive network of fine processes within the surrounding neural tissue, interacting extensively with neighboring neurons and blood vessels. Fine glial processes surround synapses and probably modulate synaptic transmission. Glial endfeet on capillaries are responsible for transport of ions and metabolites and possibly control blood flow. Alterations in these fine structures may be of significance in brain function and disease. Glial fibrillary acidic protein (GFAP) is an intermediate filament found in astrocytes of the central nervous system. GFAP is commonly found in the perikarya and processes of protoplasmic and fibrous type astrocytes. Immunohistochemical labeling of GFAP is extensively used as a means of determining the location and shape of astrocytes. However, its labeling pattern varies with brain region (e.g. cortex vs. hippocampus), with cell state (natural vs. reactive astrocytes), and with the specific α- GFAP antibody used. Furthermore, Golgi-stained or dye-filled astrocytes show numerous small appendages or vellate structures that conform to the surrounding tissue and do not stain for GFAP.

Two infants with thrombocytosis and significant neurological symptoms are presented. The electrocardiographic and vectorcardiographic findings in both suggested apical myocardial infarction. The isoenzyme studies done in one infant, however, did not support this diagnosis. This observation raises the possibility that the electrocardiographic and vectorcardiographic abnormalities may be due to associated central nervous system disease rather than due to a compromised coronary blood flow.
