Summary
In rabbits blood was taken simultaneously from the right heart, aorta, vena cava caudalis,
and vena portae. The samples were examined for activities of factors II, VIII, X,
contact activation product, antithrombin III, anti-plasma-thromboplastin, for thrombin
time, fibrin polymerization time, R+K values in the TEG and platelet count. The parameters
were found to change significantly during circulation. The greatest differences were
found between right heart on the one hand, and renal vein and portal vein on the other.
In 8 of 10 cases the arithmitical means of the tested parameters showed highest or
lowest values respectively in the renal vein.
