[Functional status and seasonal changes in white blood cells in submarine personnel in the Kola Polar region].

Evaluated was potentiality of the blood leukocyte count analysis proposed by L.H. Garkavi et al. (1985-1990) within the program of submariners health monitoring. Leukograms of 573 sailors on active service in a large nuclear submarines unit and 455 divers of a formation of ships removed from an active unit of nuclear submarines for utilization. Seasonal variations in the functional state of submariners were revealed. The most noticeable differences in these two large groups of sailors were associated with particular months. Results suggest, first of all, serious adaptive loads on the physiology of submariners on military service in the Kola polar. Burden of these loads varies with seasons and has some peculiar features which means that health-improving programs should be developed for each season and each specific group of submariners, and Garkavi's method should be standardized to be applicable to the Kola polar population.
