    The effect of water-extractive components solutions (extracts) from heshiko and narezushi, fermented mackerel products, on plasminogen activator inhibitor type-1 (PAI-1) was investigated in rats. Administration of heshiko and narezushi extracts tended to suppress the increase in both PAI-1 activity and total content associated with high-fat diet administration in rats. PAI-1 activity but not total content showed a relation to plasma triglyceride level and a reverse relation to tPA activity before and after administration of heshiko and narezushi extracts. The extracts directly inhibited PAI-1 activity in vitro, and the inhibitory activity was not lost after alimentary enzyme digestion of the extracts. The PAI-1 inhibitory activity of heshiko extract was tended to be stronger than that of narezushi extract. These results suggest that heshiko and narezushi extracts are closely involved in the promotion of fibrinolytic activity via direct PAI-1 inhibition as well as indirect suppression by decreasing the plasma triglyceride level.
