Summary: Biological tissues and organisms are quite diverse formations with different electrical resistances, which can change when exposed to an electric current. This makes it difficult to measure the parameters that characterize the electrical properties of organs and tissues. A perspective direction for diagnostics and biomedical studies of the permeability of biological tissue is the measurement of the dependence of the electrical conductivity of biological tissues on the frequencies of electric current. The amount of electrical conductivity depends on the number of free electric charges and their mobility. The basis of this study is the task of creating a measuring system and an algorithm for finding the most optimal form and parameters of an electrical signal, to provide the necessary depth and speed of penetration of pharmacological agents into biological tissue, and, consequently, to ensure the greatest effectiveness of the therapeutic effect. As a result of the experiments, the influence of the frequency and time of pulsed electrophoresis on the depth of introduction of a solution of iodine and diamond greens into adipose tissue was studied. The ranges of the most optimal frequencies for the introduction of pharmacological drugs in the electrically active state, in combination with the action of electric current, are established.

Keywords: electroconductivity, penetration of biological tissue, pharmacological preparations.

Summary: The state detection nervous and mental disorders in patients (students) by rapid analysis of electrical signals cortex discovered. The method of signal processing by spectral analysis is discribed. The results of research electroencephalogram brain signals to control the alpha rhythm, its spectral correlation analysis and comparison of the characteristics of these values in healthy patients and appearance of the indicators of mental disorder. Nobility parameters electroencephalogram performed by using bipolar complex KL-720 to a representative group of students. The methodical identify symptoms of the disease and therapeutic correction of the local correlation to the states of depression, stress or depression by acting imbalance signals corresponding frequencies.

Key words: electroencephalography, anxiety and depressive disorders, mental states, brain, spectral analysis.
