Summary

The blood clearance of purified plasmin degradation products (X, Y, D-dimer, Dcate, D EGTA, E-fibrin, Ecate and E EGTA) of rat fibrin(ogen) has been studied in a homologous system. Transcapillary flux rate constants, fractional catabolic rate constants and the ratios of intravascular and extravascular pools have been calculated. There are considerable differences in these constants between the two early fibrinogen degradation products X and Y. Also the differences between fibrinogen D and E fragments, derived from different parts of the fibrinogen molecule, are considerable. However, the differences between fibrin fragment D-dimer and fibrinogen fragment Dcate are relatively small. Also the differences between fragments E-fibrin, Ecate and EEGTA are small. The main fraction of all E-fragments is extravascular.
