in a study comparing the in vitro effects of heparin and a low molecular weight heparinoid ( organon 10172 ) on aggregation of platelets from normal subjects , we have demonstrated that whereas heparin markedly enhances platelet aggregation induced by other aggregators and inhibits the anti-aggregatory effect of epoprostenol ( prostacyclin , pgi2 ) , heparinoid does not produce such effects .
