Changes of Catecholamins and Rheological Characteristics of Human Blood Under Influence of Heliogeophysical Factors

Abstract

Correlation properties of variations of the number of hospitalized people with cerebrovascular disorders and characteristics of solar, ionosphere and geomagnetic activity have been analyzed in the article. The hypothesis was checked, that one of the internal reasons of observed biotropical effects was the level of increased catecholamins and changes of agregative properties of blood erythrocytes. The found effects are statistically significant and specify in presence of direct influences of physical processes during indignations on blood cells. Physical processes influencing cerebrovascular shifts in humans have been discussed. It has been supposed that in a storm initial stage the stochastic resonance can be one of the physical mechanisms of external influence. External electromagnetic fluctuations can synchronize or desynchronize rhythms of electromagnetic fluctuations of blood cells. Also the possibility of direct influence of geomagnetic variations during storms on the brain and the rheological properties of blood connected with influence of an electromagnetic field on dynamics of the process of aggregation - disaggregation of erythrocytes in a blood stream as in experiments in vitro and in vivo has been discussed.
