Objectives: This study aimed to ascertain what should be considered in the "Guideline for Clinical Trials with Herbal Medicinal Products for Colorectal Cancer" by analyzing the existing guidelines and clinical trials. Methods: The development committee searched guidelines for herbal medicinal products for colorectal cancer that have already been developed. Then, clinical trials for colorectal cancer using herbal medicine were searched. The searched trials were analyzed in terms of inclusion and exclusion of participants, intervention, comparator, outcomes and trial design. Then, we compared the results of our analysis with the regulations and guidelines of the Ministry of Food and Drug Safety in order to identify the issues we will have to consider when making the "Guideline for Clinical Trials with Herbal Medicinal Products for Colorectal Cancer". Several guidelines for anti-tumor agents and clinical trials with herbal medicinal products were searched on the national institution homepage. In addition, 12 articles were searched using a combination of the following search terms: 'colorectal neoplasms', 'herbal medicine', 'Medicine, Korean traditional', 'Medicine, Chinese Traditional', 'medicine, East Asian medicine', 'medicine, Kampo', etc. Results: The characteristics of participants were various, such as people with medical histories of surgeries or recurrent cancers or who complained of chemotherapy-induced side effects. The types of interventions were also various and included decoctions, powders, intravenous fluids, intraperitoneal injections and gargles. Comparators used included placebos and conventional treatments. The outcome measurements used in the studies were quality of life, symptom score, tumor response, and survival duration, etc. Safety was evaluated by recording adverse events. Conclusions: Findings were made by reviewing existing guidelines and comparing them with clinical trials for colorectal cancer and herbal medicinal products. These results will be utilized in the development of the "Guideline for Clinical Trials with Herbal Medicinal Products for Colorectal Cancer".

Background: Type I allergy is involved in allergic asthma, allergic rhinitis, and atopic dermatitis which are accompanied by an acute and chronic allergic inflammatory responses. Rehmannia glutinosa is a traditional medicine in the East Asian region. This study examined whether a Rehmannia Glutinosa pharmacopuncture solution (RGPS) had anti-allergic or anti-inflammatory effects in antigen-stimulated-RBL-2H3 cells. Methods: We determined the effect of RGPS on cell viability using the 3-[4,5-dimethylthiazolyl]-2,5-diphenyltetrazolium bromide (MTT) assay. We also examined the effect of RGPS on the release of ${\beta}$-hexosaminidase and the secretion of IL-4 and TNF-${\alpha}$ using ELISA. In addition, we evaluated the effect of RGPS on the mRNA expression of various cytokines; IL-2, IL-3, IL-4, IL-5, IL-13 and TNF-${\alpha}$ using RT-PCR. Furthermore, we assessed the activation of mitogen-activated protein kinases (MAPKs) and nuclear factor (NF)-${\kappa}$B using Western blotting after RGPS treatment. Results: We found that RGPS ($10^{-4}$ to $10^{-1}$ dilution) did not cause any cytotoxicity. We observed significant inhibition of ${\beta}$-hexosaminidase release and suppression of the protein secretion of IL-4 and TNF-${\alpha}$ and mRNA expression of multiple cytokines in antigen-stimulated-RBL-2H3 cells after RGPS treatment. Additionally, RGPS suppressed not only the phosphorylation of MAPKs, but also the transcriptional activation of NF-${\kappa}$B in antigen-stimulated-RBL-2H3 cells. Conclusions: These results suggest that RGPS inhibits degranulation and expression of cytokines including IL-4 and TNF-${\alpha}$ via down-regulation of MAPKs and NF-${\kappa}$B activation in antigen-stimulated-RBL-2H3 cells. In conclusion, RGPS may have beneficial effects in the exerting anti-allergic or anti-inflammatory activities.

Objectives : Polygoni Multiflori Radix (Jeokhasuo in Korean) is a Oriental traditional herbs widely used in East Asian countries. Overconsumption of fructose results in hypertension, dyslipidemia, obesity and impaired glucose tolerance which have documented as a risk of cardiovascular diseases. This experimental study was designed to investigate the beneficial effects of an ethanol extract from Polygoni Multiflori Radix (PMR) in high-fructose (HF) diet-induced metabolic syndrome rat model. Methods : Sprague-Dawley (SD) rats were divided into three groups; Control group, receiving regular diet and tap water, HF group, and HF + PMR group both receiving supplemented with 65% fructose (n=10), respectively. The HF + PMR group initially received HF diet with PMR (100 mg/kg/day) for 8 weeks. Results : PMR significantly prevented the metabolic disturbances such as hyperlipidemia, hypertension and impaired glucose tolerance. Chronic treatment with PMR significantly decreased body weight, fat weight and adipocyte size, suggesting a role of anti-obesity effect. PMR led to improve the hyperlipidemia through the increase in HDL cholesterol level as well as the decrease in triglyceride and LDL cholesterol level. In addition, PMR suppressed adhesion molecules and endothelin-1 (ET-1) expression in aorta resulting in the decrease of hypertension. In muscle tissue, PMR significantly recovered the HF-induced insulin resistance through increase of insulin receptor substrate-1 (IRS-1), p-$AMPK{\alpha}1/2$, and p-Akt expression. PMR improved HF-induced metabolic disorders and its action was caused by energy metabolism-mediated insulin signaling activation. Conclusions : These results demonstrate that PMR may be a beneficial therapeutic for metabolic syndrome through the improvement of hyperlipidemia, obesity, insulin resistance and hypertension.

Objectives : Ephedrae Herba has been used in the East Asian traditional medicine, for treatment of asthma, cold and influenza. Silymarin is an effective antioxidant and its anti-fibrogenic, anti-inflammatory, and hepatoprotective properties have been reported. This study was performed to explore an anti-fibrogenic potential of Ephedrae Herba extract (EHE) + silymarin on immortalized human hepatic stellate cell line, LX-2 cells. Methods : We studied the anti-fibrogenic effects of EHE + silymarin on transforming growth factor β1 (TGF-β1) signaling pathway in LX-2 cells. Cell viability was measured using the MTT assay. mRNA levels were detected by real-time PCR. TGF-β1 signaling-related proteins expression were detected by Western blot. Results : Silymarin 30 ㎍/mL and EHE 100 ㎍/mL showed cytotoxicity on LX-2 cells. Therefore, the concentrations of silymarin and EHE were studied at 10 ㎍/mL, respectively. Silymarin significantly reduced PAI-1 protein expression, Smad binding element (SBE) luciferase activity, and mRNA (PAI-1, MMP2 and 9) expression compared to TGF-β1. EHE significantly reduced SBE luciferase activity and mRNA (PAI-1, MMP2 and 9) expression compared to TGF-β1. More importantly, EHE + silymarin significantly reduced all parameters compared to TGF-β1, and also significantly reduced compared to EHE alone and silymarin alone. Conclusion : The results indicate that EHE + silymarin has anti-fibrogenic effect in LX-2 cells induced by TGF-β1. Additionally, EHE + silymarin shows more effective anti-fibrogenic effect than EHE alone and silymarin alone.

Objective : Ephedrae Herba (Ephedra) has been frequently used in the East Asian traditional medicine including Korea, China and Japan in the clinical treatment of asthma, cold and influenza etc. This study was performed to explore an anti-fibrogenic potential of Ephedra Herba water extract (EHE) using immortalized human hepatic stellate cell line, LX-2 cells. Methods : We examined the anti-fibrogenic effects of EHE on canonical pathway of transforming growth factor-β1 (TGF-β1) signaling in LX-2 cells. Cell viability was measured using the MTT assay. mRNA levels were detected by real-time PCR. Proteins expression were detected by Western blot. Results : Treatment of EHE 30 ㎍/ml did not show any cytotoxicity on LX-2 cells. Pre-treatment of EHE (30 ㎍/mL) significantly inhibited α-smooth muscle actin expression induced by TGF-β1. Additionally, EHE significantly decreased Smad2 and Smad3 phosphorylations, Smad binding element-driven luciferase activity and plasminogen activator inhibitor type 1 expression by TGF-β1. Furthermore, increases of matrix metalloproteinases 2 genes by TGF-β1 was also attenuated by EHE treatment. Conclusion : These results suggest that EHE has an ability to suppress fibrogenic process in activated HSC via inhibition of TGF-β1-TGFBR mediated canonical (Smad dependent) pathway.

Purpose: The purpose of this study was to address differences between mental health according to sasang constitution and ego state among college students. Methods: Data for this cross-sectional study were collected by administration of questionnaires eliciting Woo's ego state scale, QSCC II for the sasang constitution classification, and SCL-90-R for mental health to 393 college students. Analysis was performed using IBM SPSS (version 19.0). Results: The Free Child ego and Adapted Child ego differed significantly among sasang types. The ego-gram pattern of So-eum type exhibited the N pattern (Nurturing Parent (NP)>Adapted Child (AC)>Adult (A)>Free Child (FC)>Critical Parent (CP), AC-high type), however, the ego-gram pattern of other constitution types showed the M pattern (NP>FC>A>AC>CP). No statistically significant differences in mental health were observed among sasang types, however, among ego states, AC and CP showed negative correlation with mental health status. Between So-eum type and So-yang type, AC was the factor predicting mental health. Between Tae-eum type and undefined type, AC and CP were factors predicting mental health. Conclusion: These findings suggest that sasang constitution could be an important factor in understanding the ego state and mental health status. We conclude that sasang constitution should be considered in interpretation of mental health status presentation in clients.

Rhizome of Alisma orientale has been used as a traditional medicine for treating kidney diseases in East Asian countries. Its inhibitory effects on hypersensitivity responses have been reported for methanol extracts, with alisol B 23-acetate (AB23Ac) being the most active constituent among six terpenes in inhibiting the direct passive Arthus reaction. However, whether AB23Ac has efficacy against allergic asthma has not been tested to date. The in vivo efficacy of AB23Ac in an ovalbumin (OVA)-induced allergic asthma mouse model was evaluated by administrating AB23Ac before OVA sensitization or OVA challenge in BALB/c mice. AB23Ac suppressed antigen-induced degranulation of RBL-2H3 mast cells in a concentration-dependent manner. The administration of AB23Ac both before OVA sensitization and OVA challenge greatly lowered pulmonary resistance and the increase in immune cell counts and inflammatory responses around the peribronchial and perivascular regions. In addition, the inflammatory cytokine levels of Th1/Th2/Th17 cells in the bronchoalveolar lavage fluid decreased in the AB23Ac-treated groups. AB23Ac reduced the number of PAS-stained cells in the lungs. Furthermore, a computer modeling study indicated that AB23Ac can bind tightly to spleen tyrosine kinase (Syk). These results suggest that AB23Ac may ameliorate allergic asthma by suppressing immune responses in dendritic cells during sensitization and in mast cells during challenge periods.

산사(Crataegus pinnatifida Bunge) 중의 생리활성물질이 이상지질혈증에 있어서 간 조직 및 간 기능 대사효소의 활성 변화 등에 생리적 효능이 있을 것으로 판단되어 Sprague Dawley계 수컷 흰쥐를 이용하여 실험을 수행하였다. 대조군인 NND군, 대조군에 산사 추출물을 섭취시킨 NNDH 군, 이상지질혈증군인 CDD 군, 이상지질혈증군에 산사 추출물을 섭취시킨 DDH 군으로 나누어 5주간 실험 사육하였다. ALP(alkaline phosphatase), LDH(lactate dehydrogenase), AST(aspartate aminotransferase) 및 ALT(alanine aminotransferase) 활성은 모두 동일한 경향을 나타내었다. NND 군과 NNDH 군 간에는 유의적인 차이가 없었다. 이상지질혈증군인 CDD 군이 가장 높은 활성을 보였고, 이상지질혈증군에 산사 추출물을 섭취시킨 DDH 군에서 감소하는 것으로 나타났다. 간장의 조직학적 검사는 NND 군과 NNDH 군에서는 어떠한 이상 소견도 발견하지 못하였으나, CDD 군에서 지방 세포의 수와 크기증가, 지방 변성 및 염증 세포 등이 관찰되었고, DDH 군에서 지방 세포의 수와 크기가 줄어들었으며, 지방 변성 등이 감소된 것을 관찰할 수 있었다. 따라서 산사 추출물은 지방세포 분화 억제 및 지방 분해 작용과 간 기능 개선 효과 있는 것으로 추정되며, 간 보호 기능성 물질로서 활용 가능성이 우수할 것으로 사료된다.

Objectives: Pharmacopuncture is considered a unique new type of acupuncture in Korean medicine (KM). This study was performed to investigate the research trends regarding pharmacopuncture through a bibliometric analysis using VOSviewer. Methods: The Web of Science Core Collection was searched for this study. The search terms were pharmacopuncture and pharmaco-puncture. The search was conducted on May 23, 2023, and 185 studies retrieved up to this date were included. Software VOSviewer version 1.6.19 was used to perform the bibliometric analysis. After data clearing, keyword co-occurrence and cooperation pattern analyses were performed. Results: The number of studies on pharmacopuncture have gradually increased since the mid-2000s, with the most published in 2020 (46 studies). The quality of the studies has also steadily increased, and recently, several randomized controlled trials of pharmacopuncture have been conducted. Moreover, this treatment has been investigated in the context of KM clinical practice guideline development in Korea. The scope of pharmacopuncture studies to date seems to be limited to musculoskeletal pain and bee venom pharmacopuncture. The researchers from Jaseng Medical Foundation have been the core researchers in the field of pharmacopuncture in Korea. They collaborated with researchers from universities or government-funded research institutes. However, small-scale research teams from KM clinics and university researchers were also identified as independent clusters. Conclusion: Pharmacopuncture research has grown both quantitatively and qualitatively, but the scope needs to be further expanded. There is also a gap between the use of pharmacopuncture by KM doctors in clinical settings and pharmacopuncture research. Based on these findings, some suggestions for future studies in this field are discussed. Furthermore, these findings may be used as data to expand and globalize pharmacopuncture research in the future.

Objectives : This research aimed to develop a new etiologic classification for traditional Korean Medicine in order to respond to the social and environmental change. Methods : We reviewed the existing theories on etiological classification for East Asian Medicine thoroughly and discussed the problems and limitations. Based on the experts' consensus, we abstracted disease factors and etiologic items. Results : The disease factors are classified into three parts: the human body, the environment, and the interaction between the human body and the environment. We defined them as the inner factor, the external factor, and the interaction between the inner and the external factors. The inner factor is free from the influence of the environment, and it causes diseases solely from the components of the human body. It is divided into genetic factors. The external factor is defined as a case when a disease occurs due to a factor outside the human body and includes external injuries, environmental pollution, and natural disasters. The interaction between the inner and the external factors is a disease factor that causes diseases by the interaction of the human body and the environment and includes emotions, habits, and social environment. As a result of the analysis, it was possible to see the meanings at a single glance as the scattered and fractional meanings were integrated with focus on medicinal herbs, but the increasing number of analyzed medicinal herbs tended to more and more complicate their relationships, thus, requiring additional work like filtering. Conclusions : The new etiologic classification of Korean Medicine fully reflects the perspectives on life in Korean Medicine while embracing the changes in modem society. Also, by avoiding the usage of ambivalent terms and wrong classification methods, the new classification system constructs intuitive and concise etiology and improves usability in clinical medicine.
