Summary
Thoracic duct lymph of the dog was compared with blood regarding the concentration
of various coagulation factors, coagulation properties, and components of the fibrinolytic
system.
The recalcification time for lymph was almost twice as long as for blood. The quotients
between the concentration of the coagulation factors in the lymph and blood varied
considerably. For fibrinogen the lymph/blood concentration ratio was 1/3, for factor
V 1/4, for factor VIII 1/4, for factor IX 2/3 and for P & P 1/2.
The fibrinolytic activity in the lymph was lower than in the blood and no split products
were found in the lymph. The lymph/blood concentration ratio was 1/2 for plasminogen
and 2/3 for the urokinase inhibitor activity.
