• (1) The pressure-flow relations in both the hepatic artery and the portal vein system were investigated in a total of 13 dog livers, perfused with the homologous blood by a pump oxygenator. In addition, the interaction between the hepatic artery and the portal vein system was also studied. Thepressures and flows in both the vascular systems were simultaneously measured by means of electromagnetic flowmeters and electric manometers.(2) HAP was successively raised by stepwise fashion from 30 to 260mm.Hg, while PVP was adjusted at about 10mm.Hg. HAF was increased proportionately less than the rise in HAP within a range of approximately 80-160mm.Hg of HAP, indicating that HAR was raised as HAP was increased. Thus, the presence of autoregulation was demonstrated in the hepatic artery system.(3) The changes in PVF during the alterations of PVP over a range of 5-40mm.Hg were examined, maintaining HAP constant at about 100mm.Hg. PVF was increased proportionately or more than the rise in PVP, indicating that PVR was unchanged or decreased as PVP was increased. Consequently, it was demonstrated that the portal vein did not autoregulate its blood flow.(4) PVR was slightly affected by the variation of HAP. On the other hand, HAR was hardly affected by the variation of PVP within a range of 5-30mm.Hg of PVP.
