Passage through the lymph node. Studies with watered and oiled contrast medium given into an afferent lymphatic.

The authors investigated the passage of watered and oiled contrast media through the lymph node. Patent Blue dye diluted in saline has delineated as a rule only a circumscript area of the lymph node according to the supplying area of the afferent cannulated. Lipiodol Ultrafluid has been found suitable for filling up the whole node: at first only a small part of the node became filled primarily from the afferent, while other parts were filled secondarily from the hilus. The compartmentalisation of the lymph node has been proved by autoradiography (3H-thymidine), too.
