Summary
By use of purified contact activation product (CAP) it was possible to show that activation
of the contact phase of the coagulation system can lead to a state of hypo-coagulability
very similar to that occurring in the experimental Sanarelli-Shwartz-man phenomenon
(SSP). The coagulation changes which occurred suggested that the difference between
the effects of CAP administration and the typical experimental SSP appeared to be
merely quantitative in nature. However, the fact that in our experiments on the classical
SSP no stasis thrombi developed as the most significant sign of increased coagulation
activity, may suggest that pathogenetically important differences exist.
