Background: Recently, beneficial roles of ginsenoside F2 (GF2), a minor constituent of Panax ginseng, have been demonstrated in diverse inflammatory diseases. However, its roles in alcoholic liver inflammation and injury have not been clearly understood. Here, we investigated the underlying mechanism by which GF2 ameliorated alcoholic liver injury. Methods: To induce alcoholic liver injury, C57BL/6J wild type (WT) or interleukin (IL)-10 knockout (KO) mice were orally administered with ethanol (3 g/kg) or ethanol-containing GF2 (50 mg/kg) for 2 wk. Liver injury and infiltration of macrophages and neutrophils were evaluated by serum biochemistry and immunohistochemistry, respectively. The changes of hepatic immune cells were assessed by flow cytometry and polymerase chain reaction analysis. In vitro differentiation of naïve T cells was performed. Results: GF2 treatment significantly attenuated alcoholic liver injury, in which infiltrations of inflammatory macrophages and neutrophils were decreased. Moreover, the frequencies of Foxp3⁺ regulatory T cells (Tregs) increased but IL-17-producing T (Th17) cells decreased in GF2-treated mice compared to controls. Furthermore, the mRNA expression of IL-10 and Foxp3 was significantly increased, whereas IL-17 mRNA expression was suppressed in GF2-treated mice. However, these beneficial roles of GF2 were not observed in GF2-treated IL-10 KO mice, suggesting a critical role of IL-10. Similarly, GF2 treatment suppressed differentiation of naïve T cells into Th17 cells by inhibiting RORgt expression and stimulating Foxp3 expression. Conclusion: The present study suggests that GF2 treatment attenuates alcoholic liver injury by increasing IL-10 expression and Tregs and decreasing IL-17 expression and Th17 cells.

The effect of leaf water content on apparent photosynthesis and respiration of tobacco plants(five varieties) was studied under the condition without the irrigation for 10 days after the plants were sufficiently watered on the first day. The wild race (N. longiflora) among varieties showed highest apparent photosynthesis (AP) and AP had a positive correlation with specific leaf weight. N. longiflora and Andongyeob were different in their AP from the other varieties significantly under the water stress condition. Respiration rate also decreased to be simillar to AP except slight increase at early stage of water deficit. The stomatal resistance and the mesophyll resistance increased in the stressed plants. The water stress resistant character seems to be mainly due to open stomata.

Pseudomonas fluorescens strain Gpf01, isolated from ginseng rhizosphere showed antiviral activity against Cucumber mosaic virus, when tested in a local host of CMV, Chenopodium amaranticolor. Transposon mutant library of Gpf01 was prepared using pGS9::Tn5 and the mutant Gpf01-RS19 was found to loose antiviral production. We developed primers from the flanking region of Tn5 and found a cosmid clone pAV1123, harboring 1.2 kb antiviral compound producing (avcf01) locus. When a sub-clone pPH9, which carried 9.3 kb region of pAV1123, was introduced into antivirus deficient P. fluorescens wild type strain B16, it exhibited antiviral activity. Using Tn3-gus mutagenesis and complementation analysis, it was found that the genes related to antiviral activity production resided in a 9.3 kb HindIII-HindIII fragment of pAV1123, indicating that the plasmid carries an essential genes promoting antiviral activity.

Objectives : The purpose of the present study is to grasp and provide basic data necessary for the establishment of korean healthcare policies in future. Methods : A questionnaire developed by the author was distributed to 299 students of D University located in Busan and collected thereafter from March 5 to June 1, 2012. Statistical processing of the data obtained was conducted using the SPSS WIN IBM 20.0 program to indicate outcomes in frequencies and percentages. Results : The results of the survey are as follows. 1. The number of students who were mainly using korean hospitals/clinics was 6(2.0%). The most important factor in selecting korean medical institutions was 'medical technology'. 2. The treatment that was received the most frequently and the most reliable at korean medical institutions was acupuncture. The most frequent reason for taking korean medicine was 'prescriptions tailored to constitutions' and the most frequent reason for avoiding korean medicine was 'high prices'. 3. There was few number of students who knew that car insurance coverage for traffic accidents include treatment at korean clinics. and who knew about 'permitted standard herbal medicine', 'the use of disposable needles', 'wild ginseng pharmacopuncture'. 4. Among items necessary for the development of korean medicine, 'treatment technology with fast and high effects' was the most frequently selected. Conclusions : University students' preference for and perception of korean medicine were shown to be very low. It is considered that public relations should be reinforced to implant correct perception of korean medicine in university students who will be major users of hospitals and clinics.

Exports of Korean non-timber forest products to the Japanese market decreased 46.3% from 17.54 million dollars in 2010 to 9.42 million dollars in 2014. This research aims to find the appropriate strategies for exporting Korean non-timber products, such as chestnut, shitake, persimmon, and wild ginseng. We applied conjoint analysis to investigate the preferences of Japanese homemakers for Korean non-timber products. The results are as follows: (1) There is a clear distinction in the preference for the attributes and levels of products; (2).Korean products are preferred to Chinese products, but have lower competitiveness than Japanese products; (3) Japanese homemakers responded sensitively, not to the forest product prices, but to changes in their specific attributes. These results can be used to promote the export of Korean non-timber products to the Japanese market.

The Hippo-YAP signaling pathway is critical for cell proliferation, survival, and self-renewal in both Drosophila and mammals. Disorder of Hippo-YAP pathway leads to tumor development, progression and poor prognosis in various cancers. YAP/TAZ are the key downstream effectors of the Hippo pathway and they can be inhibited through LATS1/2, core kinases in the Hippo pathway, mediated phosphorylation. In this study, we investigated the effect of Angelica gigas Nakai extract (AGNE) on Hippo-YAP/TAZ pathway. First, ANGE induced YAP/TAZ phosphorylation and dissociation of the YAP/TAZ-TEAD transcription complex. By qRT-PCR, we found that ANGE inhibits the expression of YAP/TAZ-TEAD target gene, CTGF and CYR61. In addition, the transcriptional activity of YAP/TAZ was not suppressed significantly in LATS1/2 double-knockout (DKO) cells by ANGE compared to LATS1/2 wild-type (WT) cells, which means AGNE inhibits YAP/TAZ signaling through direct action on LATS1/2. Further, it was confirmed that AGNE-induced activation of LATS1/2 inhibited the migration potential of the vector-expressing cells by suppressing YAP/TAZ activity. The reduced migration potential was restored in active YAP-TEAD expressing cells. Taken together, the results of this study indicate that ANGE downregulates YAP/TAZ signaling in cells through the activation of LATS1/2.

Objectives: High natural killer cell activity (NKA) is associated with a clinically favorable status in patients with cancer. This study explores whether traditional Korean medicine (TKM) improves NKA in patients with cancer. Methods: We report three clinical cases involving patients with cancer who underwent NKA tests while they received TKM treatment, including acupuncture, moxibustion, wild ginseng pharmacopuncture, and Korean herbal medicines. We analyzed the treatment process and NKA test results of each patient. Results: The NKA of all three patients presented with an increasing tendency during the treatment process. Patient 1, who had been diagnosed with breast cancer, received inpatient treatment 3 times between September 16, 2017 and February 27, 2019. The NKA increased from 7.2 pg/mL to 571.7 pg/mL. Patient 2, who had thyroid cancer, was hospitalized 4 times between July 23, 2019 and August 27, 2020. The NKA improved from 317.4 pg/mL to 2000 pg/mL. Patient 3, who had liver cancer, received inpatient treatment 4 times between May 27, 2016 and January 10, 2017. The NKA increased from 22.2 pg/mL to 459.5 pg/mL. The chief complaints of these patients also were alleviated. Conclusions: TKM may be an effective treatment for accelerating NKA. Further research is needed to establish evidence that TKM stimulates NKA.
