In experiments on rabbits the red cell count was determined in venous blood from the brain and hind limbs. It appeared that under normotensive conditions the red cell concentration in blood from the brain is by ca. 20% higher than in the peripheral blood of the same animals. The differences increased (by ca. 34%) under hypotensive conditions. These results are considered as new evidence for the phenomenon of specific distribution of red cells in the arterial ramifications of the organs where the blood flow rate and metabolic demands are the highest.
在对兔子的实验中，测定了来自大脑和后肢的静脉血中的红细胞计数。结果显示，在正常血压条件下，大脑血液中的红细胞浓度比同一动物外周血中的红细胞浓度约高20%。在低血压条件下，这种差异增大了（约34%）。这些结果被视为红细胞在器官动脉分支中特异性分布现象的新证据，这些器官的血流速度和代谢需求最高。
