Studies on the Lymph Node-Venous Communications II. The Passage of Labeled Exogenous Erythrocytes

---

Abstract

The passage of ⁵¹Cr labeled avian erythrocytes has been followed through the medial retropharyngeal lymph node of the dog by injecting labeled avian erythrocytes into one afferent lymphatic channel and assaying for radioactivity in samples recovered from the efferent lymphatic channel, the adjacent internal jugular vein, and distally from the femoral vein. Profiles of recovery were consistent with those found when using radioactive iodinated serum albumen. A secondary peak of recovery from the efferent lymphatic channel and adjacent internal jugular vein coincided with timed nodal palpation. The amounts of nodal retention and transnodal passage were quantitated and discussed in terms of passage rates and possible clinical relevance. The transnodal passage of avian erythrocytes suggests the size of the lymph node-venous communication to be on the order of a capillary or larger.
