[Clinical results and prospects for the use of phenosanic acid in patients with focal epilepsy]. / Klinicheskie rezul'taty i perspektivy primeneniya fenozanovoi kisloty u vzroslykh patsientov s fokal'noi epilepsiei.

OBJECTIVE: To study the efficacy and safety of using a new original synthetic antioxidant - phenosanic acid as an adjunct therapy in patients with focal epilepsy. MATERIAL AND METHODS: A randomized, double-blind, placebo-controlled, parallel-group study evaluated the efficacy and safety of phenosanic acid as an adjunct therapy to basic antiepileptic drugs in 120 patients with focal epilepsy. Primary purpose: to study the dynamic of seizure frequency. Secondary purposes: to study the dynamic of seizure-free days, the dynamics of bilateral tonic-clonic seizures, the results of questionnaires and scales (General Dynamics Assessment, Visual Analogue Scale (VAS), Quality of Life in Epilepsy (QOLIE-31-P), European Quality of Life Questionnaire (EQ-5D), Hospital Anxiety and Depression Scale (HADS), Frontal Asstssment Battery (FAB), Mini-Mental State Examination (MMSE)). RESULTS: Phenosanic acid (Dibufelon) showed statistically significant benefit over placebo in the primary indicator of efficacy (reduction in the frequency of epileptic seizures by at least 50%) and in the secondary indicators. The drug was safe and well tolerated by the patients. CONCLUSION: The addition of phenosanic acid (Dibufelon) to base antiepileptic drugs seems to be perspective because of its positive effect on reducing the number of epileptic seizures, as well as on comorbid disorders in the emotional and cognitive spheres.

[New opportunities in the optimization of epilepsy treatment in adolescents]. / Novye vozmozhnosti optimizatsii terapii épilepsii u podrostkov.

In the pubertal period, the most severe forms of childhood epilepsy persist and are modified; genetically determined syndromes, atypical for early and late age periods, make their debut. Hereditary predisposition, instability of homeostatic mechanisms, neuroendocrine restructuring at the age of puberty and the influence of factors contributing to the realization of a genetic defect lead to a long-term transformation of mediator systems and formation of epileptic activity in adolescents. The authors present common approaches in the treatment and characterization of the modern antiepileptic drug perampanel, which is highly effective in treatment of patients with resistant forms of epilepsy. The article presents a summarized overview of the clinical forms of adolescent epilepsy observed in a psychoneurological department and an analysis of treatment results. A clinical case of the successful use of the antiepileptic drug perampanel in a female patient with focal seizures with secondary generalization of epilepsy, type I neurofibromatosis is presented.

2-Morpholino-5-Phenyl-6H-1,3,4-Thiadiazine Corrects Metabolic Disorders during the Development of Alloxan Diabetes Mellitus in Rats.

Metabolic disorders were evaluated in rats with alloxan diabetes mellitus after administration of 2-morpholino-5-phenyl-6H-1,3,4-thiadiazine (compound L-17). Administration of L-17 reduced the severity of metabolic disorders associated with diabetes mellitus. At the end of the experiment, the concentration of glucose, glycated hemoglobin, malonic dialdehyde, and catalase activity were significantly higher and peroxidase activity was significantly lower in the group of animals receiving L-17. The decrease of glycemia, glucose concentration, and glycated hemoglobin content was reached by the 3rd-4th week of the experiment. These data suggest that correction of biochemical parameters in rats with alloxan diabetes was reached after administration of L-17 for at least 3 weeks.

Formation and realization of individual experience.

This article describes the methodological approach of systemic psychophysiology. In the framework of this approach a wide range of experimental data is analyzed: results of neuronal recordings in vitro and in awake normal and pathological animals learning to perform and performing both complex instrumental and simple behavioral acts. Another block of analyzed data is based on experiments with human subjects who learn and perform the tasks of categorization of words and operator tasks, participate in group game activity, and answer the questionnaires of psychodiagnostic methods. As a result of this analysis, the systemic psychophysiology approach is used to describe qualitatively and quantitatively the formation and realization of individual experience.

P300 and psychophysiological analysis of the structure of behavior.

P300 wave was analyzed on the basis of comparison between brain potentials, the structure of behavior and single unit activity within the signal detection task through experiments with humans and animals. The similarity of the late positive components following detected light flashes in humans and rabbits, identified as P300, permitted the use of data concerning single unit activity. The analysis of single unit activity in the visual and motor cortex of rabbits demonstrated that the sequence of behavioral stages in signal detection is based on different sets of units. There is a strong correspondence between the change of set and the P300 development. Since the activity of certain units in behavior reflects the realization of certain functional systems, the modification of the sets of activated units indicates the transformation of the composition of functional systems of different hierarchical levels during the change of behavioral stages. This is the basis for our suggestion that P300 reflects the process of reorganization of the structure of the behavior which is responsible for the transition from one stage of behavior to another.
