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.

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.

Introduction. The priority indicator of the influence of chemical factors of the environment on the health of the population of Russia is the pollution of atmospheric air, the composition of which is largely determined by regional features of production. Material and methods. A comparative hygienic assessment of the quality of the atmospheric air of the territory with the placement of aluminum production and the territory without similar sources of emissions was conducted; a chemical-analytical and clinical laboratory examination of 135 children was carried out, with an assessment of the negative effects from the nervous system in the case of aerogenic exposure to aluminum and manganese. Results. In the conditions of the existing quality of atmospheric air in the residential area in the zone of influence of aluminum production which forms an aerogenic exposure of substances (aluminum and manganese), possessing of the unidirectional negative impact on the central nervous system, at the level of 0.0015g/(kg∙day) the share of aluminum is 93.3%, which indicates its primary impact on the population. Children of the observation group 1 showed urine aluminum content by 3.1 times more than in comparison to observation subgroup 2 and 6.9 times in relation to the comparison group (p = 0.0001). The concentration of aluminum as a marker of inhalation exposure is substantiated, and its value more than 0.053 mg/dm3 in urine may indicate an increased risk of neurotoxic exposure. An increased prevalence (1.6-5.5 times) of the negative impact on the CNS in the form of the asthenic autonomous syndrome, as a predictor of attention deficit and hyperactivity disorder, has been shown to be associated with the aerogenic exposure to aluminum. In children with an elevated aluminum content in urine comparing to the reference level, revealed laboratory abnormalities and indices were proved to be associated with an elevated concentration of aluminum in the urine relative to the children of the comparison group: an increase in the level of neuron-specific enolase in the serum indicating an increase in the activity of damage to the blood-brain barrier; an increase in the glutamic acid content by 1.3 times, characterizing the imbalance of the neurotransmitters of the central nervous system; reduction in serum phosphorus, reflecting the antagonistic effect of aluminum, followed by an increase in the level of ionized calcium in the blood. The contribution of aluminum to the biochemical and functional indices deviation from the physiological norm accounted for from 10% to 58%. On the basis of a consistent chain of reliable dependencies, a complex of biomarkers of the asthenic autonomous syndrome and attention deficit and hyperactivity disorder associated with an elevated aluminum content in urine, including glutamic acid, neuron-specific enolase, and phosphorus is substantiated.

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.

Amino Acids Profile

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.

Minor Physical Anomalies

The paper by Quinn and Rapoport1 in the May issue of Pediatrics indicates a higher incidence of minor physical anomalies ("stigmata") in hyperactive boys compared to a control group. The authors believe that the presence of stigmata are a clue to the occurrence of insults affecting the fetus during early development. It is suggested that the hyperactive behavior disorder is also a result of the same insult affecting the central nervous system during early morphogenesis.
