  • Objectives: Korea has a unique history of being both a recipient and a donor of Official Development Assistance (ODA), and the international community expects Korea to contribute to the development of developing countries by utilizing this experience. Traditional Korean medicine (TKM) seeks to contribute to global health, however the concept of ODA has been unclear and there has been no clear strategy and sustainable initiatives. Methods: This study examines the concept of ODA and its application in global health, including business objectives, scale, evaluation principles, and development strategies. Additionally, we reviewed the current status of Traditional Korean medicine globalization projects and conducted a SWOT analysis of the internal and external environment of the TKM sector. Based on these findings, we redefined the concept of ODA for TKM and proposed suggestions for its development. Results: The current study identified key ideas for TKM ODA. It should prioritize the improvement of primary healthcare in recipient countries, aligning with the international evaluation criteria of the SDGs. Secondly, TKM's 70 years of experience can be leveraged to enhance both the competence and economic benefits of recipient countries' medical systems. Based on these concepts, a TKM ODA development model was proposed, comprising two core visions, three development strategies and goals, and six core values. Conclusion: This study systematically examined the TKM in global health and suggested sustainable development strategies for TKM ODA. Through its expansion, TKM could contribute to the advancement of global traditional medicine and its overall engagement in healthcare.

  • Through the whole period of the twentieth century, Chinese Traditional Medicine has been affected by the political and cultural changes of Chinese society. Before the 1949 Communist Revolution, Chinese Traditional Medicine was regarded as a dark past which should be cleared off. But Chinese Traditional Medicine has been reevaluated as a national medicine and spreaded quickly since the 1949 Communist Revolution. Moreover, 'the bare foot doctor' who received short term training appeared during the Cultural Revolution. It enhanced the status of Chinese Traditional Medicine. At the same time, it was estimated as a model of the self-reliant development of Third World countries. But the direction of development of Chinese Traditional Medicine was changed again recently. Chinese government has adapted the open-economy policy since the late 1970s. Accordingly Chinese Traditional Medicine also has been changed. Nowadays it pursues the professional development strategy. This paper inquired the following research questions. First, what kind of historical changes in the development strategy of Chinese Traditional Medicine has happened? Second, how much Chinese Traditional Medicine has accomplished the professionalization? Third, what kind of problems Chinese Traditional Medicine has met in the process of professionalization? Finally, why Chinese Traditional Medicine has adapted the professional development strategy?

  • Asparagus oligoclonos is one of the endemic halophytes used folk medicine in Korea. We isolated the main compound rutin from methanol extracts of A. oligoclonos based on nuclear magnetic resonance and TOF ESI-MS data. We have investigated the quantitative analysis method of main compound using HPLC and the results exhibit that rutin content of A.oligoclonos were 1.816%. To explore anti-oxidant from A. oligoclonos ethanol extracts (AOE), we investigated the antioxidant effects of AOE on $H_2O_2$-induced oxidative stress in RAW 264.7 cell. AOE were reduced $H_2O_2$-induced oxidative stress via enhancement of cell viability, and AOE significantly decreased ROS production depending on concentration. Next, to screen for anti-inflammatory activity of AOE, we investigated the inhibitory effects of AOE in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages. AOE had no effect on cell viability at a concentration of $500{\mu}g/mL$. Nitric oxide (NO) production inhibited in a dose-dependent manner. These results suggest that AOE may be a useful antioxidant and anti-inflammatory agent.

  • Lentinus edodes (LE) is the first medicinal macrofungus to enter the realm of modern biotechnology. Lentinus edodes is well-known to have anti-tumor, anti-inflammatory, and immunomodulatory effects. In this study, osteoporosis was induced by ovariectomy in female rats, and the prevention and treatment efficacy of the climacteric disease the postmenopausal type I pattern was examined using the experimental substance. Female rats were either sham-operated (sham; n = 5) or surgically ovariectomized (OVX; five animals per group) and then administered to OVX control, raloxifene hydrochloride 1 mg/kg/day, or LE (20 and 200 mg/kg/day) for 12 weeks. LE treatment suppressed the ovariectomy-induced reduction of bone mineral density in the entire tibia as well as its metaphysis with a decrease of serum osteocalcin and interleukin-6 levels. In addition, LE is suggested to elevate the serum levels of progesterone hormones and prevent bone loss in ovariectomized rats. In conclusion, LE 200 mg/kg/day may have inhibitory effects on osteoporosis in OVX rats.
