| Outline of Final Research Achievements |
In this study, we analyzed the effects of dietary factors on venous thromboembolism using multiple mouse models. Ingestion of n-3 polyunsaturated fatty acids, black vinegar and black vinegar insoluble residue was effective in suppressing the aggravation of deep vein thrombosis and pulmonary thromboembolism in mice. Among the n-3 polyunsaturated fatty acids, eicosapentaenoic acid and docosahexaenoic acid were particularly effective, and improved venous thromboembolism mainly through suppression of platelet function. Although α-linolenic acid was relatively less effective, it may have a peculiar inhibitory activity on blood coagulation reactions. The black vinegar concentrate reduced the symptoms of venous thromboembolism mainly through suppression of coagulation function. Administration of black vinegar insoluble residue suppressed platelet aggregation and reduced venous thromboembolism.
