[Effects of chronic hypokinetic stress on microhemodynamics of tissue]

By laser Doppler flowmetry investigated tissue microhemodynamics rats kept hypokinesia under 10 days. Investigation of the structure of rhythms blood flow oscillations in microvasculature revealed that chronic hypokinetic stress leads to a significant reduction of the oscillator and nonoscillation microhemodynamics indicators, reflected in the development of vasoconstriction, reducing the metabolic function of the endothelium and the allocation to them of nitric oxide, a violation of inflow and outflow of blood, the dominance of shunt blood flow, decreasing the number of functioning capillaries.
