[Physiological changes in the blood leukocyte system of sailors]

The complex appreciation of qualitative and quantitative changes in leukocyte blood system of sailors was performed. After short cruise there were moderate deviations of several hematological indexes that determine the dependency between quantity of leukocytes in peripheral blood and their functional characteristics. The biggest deviation of indexes, that testifies about metabolic changes comes to 9-14%, and immunobiological changes-up to 20-33%. After middle cruise the deviation comes to 15-23% (intracellular metabolism), and to 39-54% (immunobiological changes). After long cruise-up to 18-23% (intracellular metabolism) and 45-65% (immunobiological changes). The application of this methodical approach may widen the possibilities of the medical control over the health of sailors.
