[Effect of extreme conditions on seasonal patterns of endocrine and metabolic processes].

The study was designed to clarify seasonal patterns of endocrine and metabolic processes and their changes under extreme conditions in Special Police Force servicemen. Hormonal status, lipid spectra, activity of lipid peroxidation and nonspecific protection systems were assessed during transition seasons. It was shown that the stay in a local armed conflict zone had marked effect on the structure of adaptive reactions. Hormonal dysregulation and impaired efficiency of protective systems were most pronounced during the autumn/winter season. Disturbed endocrine regulation in winter/spring resulted in undesirable changes of lipid metabolism and increased load on the protective function mediated through bioactive radicals.
