The influence of experimentally induced pathological states on the flow and composition of central lymph in the rat.

The flow of central lymph in the rat was examined and its concentration of total proteins was determined. Experiments were performed both on healthy animals and on animals with experimentally induced pathological states. The following results were obtained: The flow of the lymph is increased in chronic liver damage, acute kidney damage and the malabsorption syndrome. On the other hand, lymph flow is decreased in fasting animals, and it is unaffected by acute liver damage. Total protein concentration was increased in fasting rats and in the group with acute liver damage, and on the contrary, it was decreased in the group with chronic damage, acute kidney damage, and malabsorption syndrome. The lymph flow or total protein concentration are not sex-dependent.
