Geomagnetic field (GMF) is one of omnipresent, essential for normal development, factors of the environment. Human activity, among others steel construction elements and stock buildings equipment attenuates GMF. Geomagnetic shielding resulted in the anatomical and physiological abnormalities during early stages of growth in and mammals, as well as increase depressive episodes and suicides and are potential reason for development of schizophrenia in individuals born after periods of increased geomagnetic activity. In the present study using an animal model of depression-chronic exposure to mild stressors we investigated if prolonged weakening of the GMF would cause decreased sucrose intake, and if it will affect the level of ACTH and corticosterone which reflects the stress status. The experiment was carried out on male Wistar rats, which were divided on three groups: group A – rats maintained in normal conditions, group B – rats were kept in weakened GMF from 2 months, and group C rats were kept in weakened GMF from two generations. Results of sucrose test could suggest greatest immunity on stress of rats kept in hypogeomagnetic conditions, but higher level of corticosterone in group of rats kept in shielding GMF can suggest, that lasting weakening the GMF was the higher stress than which was caused by other stressors used in an animal model of depression. This study was performed under project DS 3210/KHDZFiZ
