  • Title: [The influence of the leukocytes on blood flow dynamics in the microvessels of the rat brain].
    Author: Shumilova TE.
    Journal: Fiziol Zh SSSR Im I M Sechenova; 1990 Apr; 76(4):459-66. PubMed ID: 2170173.
    Abstract:
    The 25-55% increase in the leucocytes concentration in the blood did not alter the character of distribution of the blood flow oscillations amplitudes whereas their frequency increased by 1.1-2.5 times. The autocorrelation analysis of fast changes of the blood flow revealed periodic components of the process under study which shifted to lesser values (from 1.5-2.0 to 1.0-1.5 seconds). Alterations of the erythrocyte flow structure occurred in the form of a greater number of colourless portions in the blood flow in the vessels under study after administration of excessive leucocytes. Fast oscillations of the blood flow in microvessels seem to be due to the passage of leucocytes through them.
