[The study of rhythmic changes in the liver hemodynamics by biophysical methods].
Data concerning some details of portal blood flow are presented. The following methods for estimations of portal and parenchymal blood flow were used: measuring of perfusion volume velocity--in vitro; flowmetric measuring of blood flow in the portal vein, liver lobe photoplethysmography and bile flow velocity--in situ; photoplethysmography--in vivo. Regular oscillations of portal parenchymal blood flow with the period about 20-90 sec. and synchronous oscillations of the bile flow velocity were found in the above mentioned experiments.
