  • Artemisia annua L. (Compositae) is an annual herb, which has been traditionally used as an antipyretic and hemostatic agent with the herbal medicine name of Cheong Ho (菁蒿) in Korea and China. In this study, five di-caffeoylquinic acid derivatives and a coumarin were determined from the hot-water extract of aerial parts of A. annua. The structures of isolates were elucidated to be 1,3-di-O-caffeoylqunic acid (1), 3,4-di-O-caffeoylquinic acid (2), 3,5-di-O-caffeoylqiunic acid (3), 1,5-di-O-caffeoylquinic acid (4) and 4,5-di-O-caffeoylquinic acid (5) and scopoletin (6). The presence of 1,5-di-O-caffeoylquinic acid (4) is firstly reported from A. annua in the current study.

  • Although Bi(脾 Spleen) is a major organ which controls digestion and absorption in Korean medicine, there also introduced another function of bi, which is called 'bitonghyul(脾統血)' that means the spleen controls(holdings) the blood. While the spleen is involved in the function of blood generation through the digestion and absorption of food, 'bitonghyul' is another expression regarding function of the spleen. The meaning of 'bitonghyul' is related with the function of keeping the blood flowing within the blood vessels, hemostasis. Comparing the function of the spleen with the mechanisms of hemostais, it is concluded that 'bitonghyul' is a physiological effects which affect hemostatic mechanisms via absorption of vitamin K.

  • The purpose of this study was to evaluate the effect of single antiplatelet treatment on delayed bleeding, in patients undergoing dental extraction. A total of 154 teeth were extracted in 94 patients with ongoing antiplatelet treatment, who were taking single antiplatelet of either aspirin or clopidogrel. All patients underwent simple dental extraction; local hemostasis was performed with gauze-biting, suturing, and/or application of a local hemostatic agent. Delayed bleeding was recorded in 5 teeth out of a total of 154 teeth after extraction, the incidence of postoperative delayed bleeding being 3.2%. The bleeding was controlled by the patients themselves, through application of pressure with additional gauze-biting. No one visited the doctor or emergency room for hemostasis. These results confirmed that patients taking single antiplatelet drugs may have teeth extracted safely without interruption of the antiplatelet treatment.

  • The efficacy of several pulpotomy methods were evaluated histologically on animal model using 6 beagles. At 1, 4, 6 weeks after pulpotomy, animals were sacrificed by perfusion method, Histomorphometric analysis was performed using computerized image analyzing system. Statistical comparisons were done using SPSS program. The following results were obtained: 1. Tissue responses after ferric sulfate treatment mainly consisted of fibrous surface layer with the underneath pulpal tissue layer containing well-preserved odontoblasts. 2. Bleeding, fibrosis and necrosis are the main reactions obsereved in electrosurgical pulpotomy and the normal pulpal tissues were limited to the apical portion. 3. In the aspect of preserving the normal pulpal tissue, ferric sulfate pulpotomy was evaluated to be superior to formocresol or electrosurgical pulpotomy.

  • The drug consists of the dried entire plant of Viola diamantica (family Violaceae). It is used for the treatment of acute pyogenic diseases such as boil and carbuncles; also as tumor, high fever, tuberculosis and astringent hemostatic. Two flavonol glycosides have been isolated from the aerial parts of Viola diamantica and could be identifed as kaempferol 7-rhamnoside and kaempferol 3,7-dirhamnoside (bright yellow needle crystal, mp $225^{\circ}$, $C_{27}\;H_{30}\;O_4\;4H_2O$). Kaempferol 7-rhamnoside and kaempferol 3,7-dirhamnoside were first isolated from Viola diamantica.

  • Transoral $CO_2$ laser microsurgery has been widely used for various laryngeal diseases. Laser cordectomy for the management of early laryngeal carcinoma has advantages with regards to oncologic results, preservation of laryngeal functions, morbidity and cost in comparison to those of open surgery or radiation therapy. $CO_2$ laser is also applicable to benign vocal fold lesions such as nodules, polyps, cysts, reinke's edema, granulomas, papillomas, hemangiomas and glottis webs. $CO_2$ laser is suitable for microsurgery because it has small focus size and hemostatic effect. We should also recognize the risks of $CO_2$ laser for safe use.

  • Laser laryngeal microsurgery is currently the primary method of treatment of various laryngeal diseases. The development of laryngeal microsurgery came from the introduction of a small spot $CO_2$ laser micromanipulator and more precise microlaryngeal instruments. $CO_2$ laser laryngeal microsurgery has enabled very precise surgery because it has small focus size and hemostatic effect. There are some limitations to the use of the $CO_2$ Laser such as adjacent tissue damage and vocal fold scarring. These problems can be minimized through understanding the mechanisms by which lasers function and correctly manipulating the parameters under a surgeon's control. We should also recognize the safety of $CO_2$ laser for the surgeon to precisely perform the procedure.

  • Twenty Artemisia species are distributed in South Korea and rich in terpenoids. Artemisia rubripes (Compositae) has been used as a Korean traditional medicine for stomachache. vomiting. diarrhea and hemostatic agent. The antimutagenic effect and essential oils of Artemisia rubripes were reported, but phytochemical study has not been fully investigated. As part of our systematic study on the terpene constituents of Artemisia species. we have investigated A. rubripes (1 kg) collected at Dae-Kwan ryung. Gangwon Province on Aug. 1997. (omitted)

  • Acquired hemophilia A (AHA) is an uncommon autoimmune bleeding disorder in which autoantibodies that affect the functions of factor VIII (FVIII) are present in the blood. The initial diagnosis of AHA is difficult as the presentations of AHA differ from those of congenital hemophilia A. Moreover, the treatment of AHA is more complex due to the presence of autoantibodies against FVIII. Here, we present a case report of postpartum AHA, to increase the perception and knowledge regarding the recognition and management of such cases. We present a young female with the chief complaint of vaginal bleeding and upper arm ecchymosis. Laboratory results exhibited isolated prolonged activated partial thromboplastin time (APTT) and FVIII inhibitors. The patient was treated with corticosteroids, FVIII concentrates, and a bypassing agent. In conclusion, unexplained postpartum bleeding, unmanageable with basic hemostatic measures, should lead to clinical suspicion of an acquired bleeding disease.
