ASSESSMENT OF SEASONAL CHANGES IN ENERGY SUPPLY OF IMMUNOCOMPETENT BLOOD CELLS IN PREGNANT WOMEN FROM DIFFERENT AREAS OF THE AMUR REGION

In order to study the seasonal effects on the energy supply of immunocompetent blood cells (IBC) in pregnant women living in different conditions of the Amur region, and to substantiate additional methods of diagnosis, prevention and treatment of the identified disorders, a study of the mitochondrial membrane potential (MMP) by flow laser cytometry was conducted in 198 subjects. The data of different types of IBC (lymphocytes, granulocytes and monocytes) at early gestation of women living in urban (Khabarovsk) and rural (Jewish Autonomous region) areas of the Amur region were analyzed. Eight (8) groups were formed according to seasons: winter, spring, summer and autumn. The results of a comprehensive survey indicate some features of intracellular bioenergy processes of IBC depending on the environmental conditions in different seasonal periods. Conditions of women from urban areas are characterized by a significant increase in lymphocytes with reduced MMP which was more pronounced in winter, and by a tendency to increase monocytes in spring-and-summer season. The state of low energy supply of IBC in rural residents differs significantly by means of granulocytes in all presented periods of a year, combinations of various types of IBC in winters and tendency to simultaneous increase in the number of all IBCs with the reduced MMP. The number of IBC with optimal MMP content in urban environment was observed in pregnant women in autumn (23.3%), in rural areas in summer (57.1%). Thus, the study has shown the need to expand the range of diagnostic methods for the formation of pregnancy complications risk groups. Determination of the substrate-energy value in the cells of the immune system is an indication for the individual selection of complex vitamin and mineral medications taking into account seasonal changes. MMP studies allow to monitor the dynamics and evaluate the effectiveness of preventive and therapeutic prescriptions.
