Introduction: In the inhabitants of the Arctic, intensification of cardiovascular diseases, decreased efficiency, amnesia and insomnia are associated with disorders of nervous system during geomagnetic disturbances. Qualitative composition of fats in a diet increases its adaptive capacity to a geomagnetic factor, as lipids determine functional state of neurocyte membrane.
Methods: It is an experimental study. 105 adult male Wistar rats divided into 7 equal groups were enrolled. Animals received a standard diet enriched with olive, flax, butter, Coregonusnasus Pallas, pork and deer fat. Behavioral activity of animals in the test "open field" was examined daily. Registration of indicators was carried out automatically using apparatus EtchoVision XT9. The research was conducted in the period of magnetic disturbances (11 of 15 days): K-index=3.04±1.3 and Z-component of the Earth's magnetic field=76.1±67.3 NT.
Results: In the group receiving the diet enriched with Coregonusnasus Pallas fat, distance traveled be a rat (p=0.001) and the speed of movement (p=0.001) were 2 times more than in the control group. The horizontal activity indicators were the highest in the group receiving this fat and differed significantly from the control group: latent time to the center of the arena (p=0.003), search activity (p=0.001). The animal's stressfulness was the lowest in the group receiving this fat compared to the control group (p=0.001).
Conclusions: The results of our study can be used for developing diets to increase adaptation to geomagnetic disturbances of population living and working in the Arctic.
