It is a fact that the existing pharmacological research method is difficult to explain the effect and mechanism of action of herbal formula of Korean medicine. We are now very pleased with the development of modern science and the development of a methodology for studying herbal formula characterized by network targets and multi-component therapeutics over the human body. In this review, systems pharmacology or network pharmacology is demonstrated how these are applied to explain the effectiveness of herbal medicine. The post-genomic era provides a unique opportunity for the two fields to understand and benefit from each other. In particular, recent research trends, research methodology, useful databases and results of research on herbal formula are introduced. China already has a policy of scientific development of traditional chinese medicine (TCM) and the development of Chinese medicine industry with a focus on herbal formula research at national level, and in Korea, it is urgent to support and nurture the methodology appropriate to the characteristics of the herbal formula in order to study the safety and efficacy of Korean medicine.

This study considers the stages of curriculum development for the integrated curriculum of Pusan National University Graduate School & Hospital of Korean Medicine, and specifically the KAS2021 (announced in 2019), improvement measures for the curriculum of the College of Traditional Korean Medicine, and the case of the College of Medicine. The introduction of integrated curriculum in the College of Traditional Korean Medicine starts from the members (doers)' agreement. In the process of development, the organization that represents the members, the organization that sets up a goal and designs the curriculum, and the organization that executes them should fulfill their own roles. The stage of development and operation should have the support system for manpower, institution, administration, and finance. The curriculum (draft) should be concrete enough to be operated in reality. For the smooth operation of integrated education, it is necessary to secure more full-time teachers than before, and it is also necessary to have an organization fully in charge of monitoring and improving the operation. For the introduction and operation of integrated curriculum in Traditional Korean Medicine education, the members' agreement, institutional change, support system, and the cultivation of manpower for the operation/evaluation/development of curriculum should be considered.

Introduction: The aim of this study protocol is to share and disclose the methodology used to develop an evidence-based clinical practice guideline (CPG) of therapeutic interventions used in Korean medicine for patients with stroke. Methods: The CPG development process will consist of two phases. In phase I, a development committee will be established, and they will decide the key questions to be answered. A systematic review and meta-analysis will be performed to answer these key questions by searching relevant randomized controlled trials and systematic reviews. Draft recommendations will be developed according to the evidence level and recommendation grades primarily determined using the GRADE methodology. Panels comprised of external experts will be formed, and surveys and a face-to-face meeting will be conducted to reach a consensus on the recommendations. A preliminary guideline will be created after final review by the development committee. In phase II, we will conduct clinical trials and economic analysis to supplement the lack of evidence found in the phase I. Conclusion: The CPG is expected to help doctors practicing Korean medicine in clinics or hospitals with making decisions based on the most reliable evidence, ultimately leading to the provision of optimal care for patients with stroke.

본 연구는 새로운 기능성 화장품 소재 개발을 위해 복분자 씨앗의 구성성분인 casuarictin을 이용하여 섬유아세포내에서의 항노화 효과를 확인 하고자 하였다. Casuarictin의 항노화 효과를 CCD-986sk 세포를 이용하여 측정한 결과, casuarictin은 UVB에 의해 증가된 ROS 발현을 억제하였으며, pro-collagen의 발현을 증가시키고 MMP-1의 발현을 억제하는 것으로 나타났다. 이는 노화 인자인 활성산소종의 생성 억제와 주름과 밀접한 관련이 있는 콜라겐의 합성 및 분해억제를 통해 항산화 및 주름개선 효과가 있는 것으로 판단되며, 따라서 casuarictin은 화장품 분야에서 항노화 소재로서의 활용가치가 있을 것으로 사료된다.

Background : Irregular meals and insufficient exercise are major modern lifestyle-related risk factors for constipation. This study aimed to examine the effects of the aqueous extract of Dendrobium speciosum var. (DM) on the improvement of intestinal function and prevention of constipation in rats. Methods and Results : Constipation in rat was induced by loperamide (4 mg/kg) injection for 5 days and rats were randomly assigned to the following groups: normal control rats (NOR), constipated rats (LOP induced) and constipated rats supplemented with dulcolax-S (POS), DMSG, 100 mg/kg (DMSG-100), 300 mg/kg (DMSG-300) and 500 mg/kg (DMSG-500). The DMSG groups showed increments in the frequency and amount of stools compared to the LOP group. Loperamide treatment markedly reduced the water content of feces, whereas DMSG administration significantly increased fecal water contents. Moreover, DMSG improved intestinal transit speed in constipated-rats. Alcian blue staining revealed increased mucus production by crypt cells and mucus contents in feces and the mucosal surface. Conclusions : In summary, DM extraction significantly improves intestinal function in rats, which indicates the effectiveness of this extract in the prevention and treatment of constipation.

In this study, the purification of the MeOH extract from the stems and leaves of Pourthiaea villosa var. brunnea using column chromatography furnished a main compound, lyoniside. The structure was elucidated on the basis of $^1H$ and $^{13}C$ NMR spectroscopic data. Quantitative analysis of lyoniside was conducted by HPLC method and the highest content of lyoniside was found in 50% MeOH reflux extraction. To investigate the anti-inflammatory effect of the lyoniside, we measured nitric oxide and pro-inflammatory cytokines such as TNF-${\alpha}$, IL-$1{\beta}$, IL-6 levels in lipopolysaccharide-induced murine macrophage cell line RAW 264.7. As a results, lyoniside decreased the level of nitric oxide and IL-6 in concentration dose dependent manner in RAW 264.7 cells.

Mitogen-activated protein (MAP) kinases play an important role in cell growth and differentiation, as well as the modulation of proinflammatory cytokines. The objective of this study was to examine the increase in the anti-inflammatory effect of Gentiana scabra Bunge (GSB), due to bioconversion with the Aspergillus kawachii crude enzyme, via inhibition of the $NF-{\kappa}B$ signaling and MAP kinase pathways in RAW 264.7 cells. The expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 in RAW 264.7 cells treated with the GSB ethyl acetate fraction bioconverted with A. kawachii crude enzyme (GE-BA), was dramatically suppressed as compared to GSB ethyl acetate fraction non-bioconverted with the A. kawachii crude enzyme (GE-UA). The phosphorylation of p38, extracellular signal-regulated kinases, and inhibitory ${\kappa}B$ in RAW 264.7 cells treated with GE-BA was further suppressed, as compared to exposure to GE-UA. Moreover, the mRNA expression of interleukin 6, interleukin 1-beta, and tumor necrosis $factor-{\alpha}$ was further suppressed by GE-BA, compared to GE-UA. Similarly, anti-oxidant activities, such as 2,2-diphenyl-1-picrylhydrazyl hydrate and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) radical scavenging activity, of GE-BA were further increased compared to GE-UA. These observations demonstrate that the anti-oxidant and anti-inflammatory activities of GSB ethyl acetate fraction increases as a result from bioconversion with the A. kawachii crude enzyme.
