title: [The effect of heparin and thromboplastin on the half-life of 125I-protein C in the blood flow of rats].
abstract: The influence of heparin and thromboplastin on the halflife of 125I-protein C in rat blood was under investigation. It was found that t1/2 of protein C was of 2.3 h. The intravenous administration of heparin resulted in the prolongation of t1/2 to 6.5 h, that could be explained by inhibition of thrombin generation. Upon the 40-min infusion of thromboplastin the rate of 125I-protein C decay in blood enhanced. That could be explained by the generation of the endogenous thrombin and participation of thrombomodulin in the protein C activation as well as in the removal of the endogenous thrombin from blood.
