[The dependence of changes in the microhemodynamics and lymph formation in the liver on the level of the arterial and portal blood flows].
In cats, when perfusing hemodynamically isolated liver with a constant blood volume, an increasing of arterial as well as portal blood flows was shown to increase hydrostatic pressure in sinusoids and lymph production in the liver, whereas decreasing of the flows decreased these parameters. The above changes of the blood flows entailed various shifts of sinusoidal hydrostatic pressure and postsinusoidal resistance. When the volume blood flow in the liver artery increased, the coefficient of sinusoidal filtration increased too, whereas an increment of the blood flow in portal vein led to its diminishing. The resistance of liver artery and portal vein changed very little both in case of increasing and diminishing of the blood flow in these vessels.
