Abstract：
:Epsilon-amino-caproic acid (EACA) induces a clinically-useful anti-haemorrhagic, mildly thrombotic state while ellagic acid (EA) induces a severe hypercoagulable one. Reversal of these states may on occasion be necessary. The effectiveness of the antiplatelet drugs, aspirin and dipyridamole (ASA/D), in reducing thrombus weight was studied in normocoagulable animals and animals made hypercoagulable with EACA (333mg/kg) or EA (1.2mg/kg). Heparin (114iu/kg) was tested in the EACA group, both alone and in combination with ASA/D. Thrombogenicity was measured by weight formed on intravenous platinum wire in one hour. In normocoagulable animals, ASA/D reduced thrombus by 32%. Ellagic acid trebled mean thrombus weight and ASA/D reduced this by 49%, but did not restore normality. EACA increased mean thrombosis by one sixth. Treatment with heparin reduced this by 48% to a level well below that of untreated animals. Addition of a single dose of aspirin/dipyridamole to the heparin regime, reduced thrombosis by a further 31%, reaching to 21% of control thrombus. The results were statistically significant. Kaolin-activated blood clotting time was shortened by EA, but EACA had little effect on it, while ASA/D slightly and heparin markedly lengthened it.
