ABSTRACT
By using the model conceptions of the dielectric polarization theory, a new mechanism for the effect of electromagnetic field was proposed. The model enables one to explain the experimentally observed influence of low-frequency weak electromagnetic field on biological objects. It was shown that, at the cellular and subcellular levels, an increase in the intensity of the electric component of external electromagnetic field can occur. The magnitude of this increase is determined by the ratio of the contributions of the medium polarization and the depolarizing factor (which depends on body shape) to the total effect. As a result of this increase, a potential comparable with intrinsic biological values can be generated on neuron membranes, which must elicit nervous and physiological responses of the organism.

On the basis of the analysis of 1023 clinical observations of hemorrhagic shock in acute gastric hemorrhage, the modern notions about the mechanisms of its development, peculiarities of the clinical course, depending on nature and volume of blood loss are stated. A scheme for intensive anti-shock therapy has been developed. The lethality after 1892 emergency operations was 3%, and in ulcer with hemorrhagic shock after 547 operations--9.3%.
