通过使用放射性同位素标记的磷酸，表明当将材料注入脾静脉时，在大约3秒内，肝脏左侧的标记P浓度明显高于右侧。的Inj。时间相反，当将相同的物质注射到肠系膜静脉的分支中时，标记物质在肝脏右侧的累积明显更大。当将其注射到颈静脉中并有足够的时间与循环血液完全混合时，从肝脏采集的各种横切面中标记材料的浓度没有明显差异。门静脉中的血液流动明显存在生理性的双侧性，其本质上是流线型的，并且通过其脾血主要被输送到肝脏的左侧，而肠系膜血被输送到肝脏的右侧。
By the use of phosphoric acid tagged with the radioactive isotope it is shown that when the material is injected into the splenic vein there is a decidedly greater conc. of the tagged P in the left side of the liver than in the right side within about 3 secs. of the inj. time. In contrast, when the same material is injected into a branch of the mesenteric vein there is a markedly greater accumulation of the labelled material in the right side of the liver. When it is injected into the jugular vein and sufficient time allowed for complete mixing with the circulating blood there are no demonstrable differences in the conc. of the tagged material in various transverse sections taken from the liver. There is evidently a physiological bilaterality of flow of blood in the portal vein which is streamline in nature and by which the splenic blood is largely sent to the left side, and the mesenteric blood to the right side of the liver.
