将同位素注入胃、十二指肠或外周静脉或门静脉后，在未麻醉水合大鼠的肠淋巴液、门静脉血和股动脉血中测量了D2O或Na 24的含量。从小肠吸收后，很少（如果有的话）水或钠离子通过淋巴途径输送到身体。至少有99%是在门静脉血中携带的。无论给药途径如何，肠淋巴中发现的同位素量与淋巴体积成比例，并且主要来自动脉血。即使在从小肠吸收水或钠离子的过程中，动脉循环也是淋巴液中水和钠的主要来源。
The content of either D2O or Na24has been measured in the intestinal lymph, portal venous blood, and femoral arterial blood of unanesthetized hydrated rats after administration of the isotope into the stomach, duodenum, or peripheral or portal vein. Little, if any, water or sodium ion is delivered to the body by a lymphatic pathway after absorption from the small intestine. At least 99% is carried in portal venous blood. The amount of isotope found in intestinal lymph was proportional to lymph volume whatever the route of administration, and derived mainly from the arterial blood. Even during absorption of water or sodium ion from the small intestine the arterial circulation is the principal source of the water and sodium of the lymph.
