Abstract:
The opportunity of an estimation of influence of low intensity microwave on processes of ionic transport through biological membranes on base electrodiffusion theories is considered. The effects which are impossible to explain within the framework of conceptions about free diffusion are listed. Basic provisions of Eiring theory of absolute speeds of reactions are described and on its basis expression for calculation of an ionic current strength is received in presence of external microwave. Calculation of an ionic current strength through a membrane according to the expression, which is made on the basis of the Nernst-Plank equation and to the expression, received on the basis of Eiring theory. On the basis of the calculation data schedules of dependence of an ionic current strength from spatial value are constructed and the analysis of the received results is made. It is shown, that at research of influence of electromagnetic fields on transport processes of ions through biological membranes expediently to use Eiring theory. In article the account of change of a potential barrier on a membrane also is resulted at presence of an external microwave field and it is marked, that feature of influence of the microwave field is periodic change of a potential barrier value, i.e. the potential barrier value becomes time function. It is shown, that low intensity electromagnetic radiation of ultrahigh frequency promotes occurrence in a biological organism of ionic currents which values within the limits of values of the ionic currents inherent in a healthy organism
