A case of combined deficiency of antithrombin III and protein C complicated by recurrent venous thrombosis / 대한내과학회지

Primary venous thrombosis caused by deficiency or qualitative abnormality of antithrombin III, protein C and protein S is usually inherited as an autosomal dominant trait. Usually, deep vein thrombosis or pulmonary thromboembolism is developed by such abnormalities, however, mesenteric vein thrombosis is rarely reported. A 27-year-old man with previous history of deep vein thrombosis underwent segmental resection of jejunum due to mesenteric vein thrombosis complicated by necrosis of jejunum. Postoperative investigation disclosed combined deficiency of antithrombin III and protein C. His son also showed deficiency of antithrombin III. Postoperatively, he is on life-long warfarin therapy without experiencing recurrence of venous thrombosis.

Salicylate Induced Apoptosis in A549 Cells / 대한암학회지

PURPOSE: Nonsteroidal antiinflammatory drugs (NSAIDs) have been shown to exist chemo preventive activity against colon cancers. In this study, we examined whether salicylate affects the survival of A549 cells, and investigated the presence of apoptosis. MATERIALS AND METHODS: We used A549 human lung cancer cell line. The measurement of cytotoxic concentration of salicylate was performed by MTT assay method. In order to test the involvement of apoptosis, we performed TUNEL assay, DAPI staining, flow cytometric analysis and RT-PCR. RESULTS: We showed that salicylate can potently induce apoptosis in A549 cells. A549 cells under went apoptosis in treatment with salicylate at pharmacological concentration (5 mM). CONCLUSION: Herein, our data provide a potential mechanism for chemopreventive activity of salicylate and suggest that salicylate may have therapeutic potential for the treatment of lung cancer.
