Summary

The generation of prothrombin-activator (thromboplastin) in water snake (Natrix piscator) is clearly delayed, Compared to a mammalian system, but the final activity is well comparable to that in man, when homologous sources of “phospholipid” (erythrocyte-lysate) and of substrate plasma are employed in one stage “thromboplastin generation test”. The use of heterologous source of either of the above reagents resulted in significantly longer clotting times; hence the need for homologous source of above reagents in the test is emphasized for comparative studies on animal haemostasis.
