title: Procoagulant activity of human stomach and colon cancers.
abstract: Procoagulant activity in extracts from human stomach and colon cancers was examined, using chromogenic substrate S-2222. The activity of direct activator of factor X varied between 6 and 96% of total procoagulant activity of the tested extracts. The direct activator of factor X from stomach cancer was sensitive to heating and was inhibited by phenylmethylsulphonylfluoride and also by iodoacetic acid and HgCl2. Such results lead to the assumption that investigated activator is of enzymatic nature.
