title: [Blood flow in the brain and liver of chicken in embryonal and early postembryonal periods].
abstract: In chicken Leghorn, blood flow volume speed (BF, laser-Doppler flowmetry) in the brain hemispheres and in liver was measured on days 10, 14, and 19 of embryogenesis and on day 4 after hatching (in experiments on late embryos and chickens, urethane narcosis was used). It was revealed, that initial BF in investigated organs was 2-fold lower than earlier measured in skeletal muscles. In the liver, low BF remained at all periods, but it grew 5-fold greater after hatching. In the brain hemispheres, the BF during this period grows gradually reaching 4-fold size in chickens. It was shown that blood stream increase in the brain was accompanied by uniform increase in anatomic lumen of internal carotid artery; thus settlement sizes of linear speed of blood flow and wall shear stress remain in it at the same level. Lumen extension of celiac artery during the observation period lags behind increases in a blood stream of in it that leads to increase in it of the named parameters.
