본 연구는 한국의 콘텐츠산업 및 관광산업에 있어 매우 의미있는 시장이지만 최근 한국 방문이 주춤했던 중국인들을 대상으로 K-콘텐츠의 가능성에 대하여 실증적으로 검증하고자 하였다. 중국 거주 중국인들을 대상으로 최근 한국을 직접 방문하지는 못하였지만 K-콘텐츠 경험이 한국에 대한 국가이미지 형성과 관광태도 및 방문의도에 유의한 영향을 미치는지를 실증적으로 검증하는데 본 연구의 목적이 있다. 연구결과, K-콘텐츠 경험, 국가이미지, 관광태도, 방문의도 각 항목들은 각각 1개의 요인으로 도출되었으며, 국가이미지 요인만 기능적 이미지, 문화적 이미지 2개의 요인으로 도출되었다. 도출된 요인들을 중심으로 기존 선행연구를 바탕으로 설정된 이들간의 영향관계를 살펴본 결과 연구가설 5개 모두 채택되었다. K-콘텐츠 경험은 국가이미지 2개 요인 모두 유의한 영향을 미치는 것으로 나타났다. 기능적 이미지 요인보다 문화적 이미지 요인에 더 큰 영향을 미치는 것으로 나타났으며, 문화적 이미지 요인은 관광태도와 방문의도에도 더 큰 영향을 미치는 것으로 나타났다. K-콘텐츠 경험은 관광태도에 유의한 영향을 미쳤고, 관광태도는 방문의도에 유의한 영향을 미치는 것으로 나타났다. 본 연구의 결과를 바탕으로 국가이미지는 결국 실질적인 관광행동으로의 연결을 위해 중요한 요인이 되며 이러한 측면에서도 무엇보다 문화가 실질적인 관광과 방문으로 연결될 수 있는 중요한 핵심 요소가 됨을 다시 한번 확인할 수 있었다. K-콘텐츠 경험은 이러한 국가 문화이미지 형성과 관광태도 및 방문의도에 유의한 영향을 줌에 따라 실제 관광행동으로 연결시켜 줄 수 있는 긍정적인 관광태도 형성을 위하여 향후 지속적인 K-콘텐츠를 활용한 다양한 세분시장별 구체적인 전략들이 수립되어 실천되어져야 할 것이다.

In this study, we investigated the free radical [1,1-diphenyl-2-picrylhydrazyl (DPPH), hydroxyl radical (${\cdot}OH$) and superoxide anion (${O_2}^-$)] scavenging activity of MeOH extract and 3 fractions of Citrus junos. Of the tested fractions, the BuOH fraction showed the strongest DPPH scavenging activity, showing the $IC_{50}$ values of 63.4 mg/mL. Therefore, we continuously carried out DPPH, ${\cdot}OH$ and ${O_2}^-$ scavenging activity tests of BuOH fraction of Citrus junos. The BuOH fraction of Citrus junos inhibited DPPH radical to 97.5% at a concentration of 1000 mg/mL and the scavenging activities were increased concentration-dependently. In addition, BuOH fraction from Citrus junos also scavenged ${\cdot}OH$ in a concentration dependent manner from 5 to 1000 mg/mL. Furthermore, BuOH fraction showed about 56% ${O_2}^-$-scavengimg activity at 25 mg/mL concentration but, the scavenging activities were not enhanced in a dose dependent manner. The present results suggest that BuOH fraction of Citrus junos would have the protective potential from oxidative stress induced by free radicals.

Objectives : To explore the associated potential pathways and molecular targets of Hwangryunhaedok-tang(HHT) by the approaches of network pharmacology and bioinformatics in traditional chinese medicine(TCM). Methods : Hwangryunhaedok-tang constituent drugs(Coptidis Rhizoma, CR; Scutellariae Radix, SR; Phellodendri Cortex, PC; Gardeniae Fructus, GF) and their processing types were searched from TCM systems pharmacology(TCMSP). The databases of TCMSP, Kyoto Encyclopedia of Genes and Genomes(KEGG), MCODE and STRING were used to gather information. The network of bioactive ingredients and target gene was constructed by Cytoscape software(version 3.8). Results : A total of 94 HHT active compounds(CR, 12; SR, 35; PC, 33; GF, 14, respectively) were found, and HHT were identified by TCMSP. Applications of KEGG and MCODE analysis indicates that total of 6 bioactive ingredients in the top 10% ranking were obtained and 32 diseases of HHT were screened. The molecular pathway analysis revealed that HHT exerts cancer, inflammation and cerebrovascular diseases effects by acting on several signaling pathway. In addition, HHT found that three genes(e.g. SPIN1, TRIM25, and APP) correlate with the aforementioned diseases. Conclusions : This study showed that network pharmacology analysis is useful to elucidate the complex mechanisms of action of HHT.

A novel mannose-binding tuber lectin with in vitro antiproliferative activity towards human cancer cell lines and antiviral activity against HSV-II was isolated from fresh tubers of a traditional Chinese medicinal herb, Typhonium divaricatum (L.) Decne by a combined procedure involving extraction, ammonium sulfate precipitation, ion exchange chromatography on DEAE-SEPHAROSE, CM-SEPHAROSE and gel-filtration on sephacryl S-200. The apparent molecular mass of the purified Typhonium divaricatum lectin (TDL) was 48 kDa. TDL exhibits hemagglutinating activity toward rabbit erythrocytes at 0.95 $\mu$g/ml, and its activity could be strongly inhibited by mannan, ovomucoid, asialofetuin and thyroglobulin. TDL showed antiproliferative activity towards some well established human cancer cell lines, e.g. Pro-01 (56.7 $\pm$ 6.8), Bre-04 (41.5 $\pm$ 4.8), and Lu-04 (11.4 $\pm$ 0.3). The anti-HSV-II activity of TDL was elucidated by testing its HSV-II infection inhibitory activity in Vero cells with $TC_50$ and $EC_50$ of 5.176 mg/ml and 3.054 $\mu$g/ml respectively. The full-length cDNA sequence of TDL was 1145 bp and contained an 813-bp open reading frame (ORF) encoding a 271 amino acid precursor of 29-kDa. Homology analysis showed that TDL had high homology with many other mannose-binding lectins. Secondary and three-dimensional structures analyses showed that TDL is heterotetramer and similar with lectins from mannose-binding lectin superfamily, especially those from family Araceae.

Recent genome-wide association studies (GWAS) have identified a number of common variants associated with blood pressure homeostasis and hypertension in population. In the previous study, single nucleotide polymorphisms (SNPs) in the SLC4A4 gene have been reported to be associated with hypertension in Han Chinese population. We aimed to confirm whether the genetic variation of SLC4A4 gene influence the susceptibility to blood pressure and hypertension in Korean population. We genotyped variants in or near SLC4A4 in a population-based cohort including 7,551 unrelated Korean from Ansan and Ansung. Here, we performed association analysis to elucidate the possible relations of genetic polymorphisms in SLC4A4 gene with blood pressure traits. By examining genotype data of a total of 7,551 subjects in the Korean Association REsource (KARE) study, we discovered the SLC4A4 gene polymorphisms are associated with blood pressure and hypertension. The common and highest significant polymorphism was rs6846301 (${\beta}$=0.839, additive P=0.032) with systolic blood pressure (SBP), rs6846301 (${\beta}$=0.588, additive P=0.027) with diastolic blood pressure (DBP), and rs6846301 (OR=1.23, CI: 1.09~1.40, additive $P=1.2{\times}10^{-3}$) with hypertension. Furthermore, the SNP rs6846301 was consistently associated with both blood pressure and hypertension. Consequently, we found statistically significant SNPs in SLC4A4 gene that are associated with both blood pressure and hypertension traits. In addition, these results suggest that the individuals with the minor alleles of the SNP in the SLC4A4 gene may be more susceptible to the development of hypertension in the Korean population.

Methanol extracts form four kinds of kimchi, which were differently prepared in kinds and levels of sub-ingredients, were given to Balb/c mice for 3 weeks (0.5 mg/kg/day). Peritoneal macrophages isolated from mice treated with kimchi extracts and saline were stimulated by lipopolysaccharide (LPS). K3 and K4 kimchis, containing more red pepper powder, garlic, Chinese pepper powder, mustard leaf and organically cultivated Korean cabbage, significantly increased NO production by the activated macrophages (p<0.05). K1, K2, K3 and K4 kimchi extracts (0.01, 0.1, 1.0 $\mu\textrm{g}$) significantly reduced the increased TGF-$\beta$1 production of H.pylori lysate (0.01 $\mu\textrm{g}$)-activated human epithelial RPMI 2650 cells (5$\times$10$^{4}$ cells/mL) at 24 and 48 hrs of treatment (p<0.01). However, the decreased TGF-$\beta$1 $\alpha$ production of RPMI 2650 cells by H. pylori lysate increased by treatment with kimchi extract for 72 hrs. Especially, K4 kimchi (containing organically cultivated Korean cabbage and more ingredients, modulated TGF-$\beta$1 production of H. pylori lysate-activated RPMI 2650 cells to the normal level (control) by treatment for 48 hrs. The treatment of K1 and K4 kimchi enhanced the LPS (0.01 $\mu\textrm{g}$/mL)-induced IL-6 production of splenocytes. The results suggest that kimchi might have an beneficial effect on cancer prevention due in part to the function enhancing NO production of activated macrophages. Our data suggest that kimchi could modulate TGF-$\beta$1 production by cancer cells and IL-6 production of splenocytes, thereby possibly contributing to control carcinogenesis and the immune system.

Three traditional Chinese medicines, Agrimonia pilosa Ledeb, Grifola umbellata (pers.) Pilat, and Gambogia, are combined to form a compound extract, AGC. In this study, the in vitro and in vivo inhibitory effects of AGC on human gastric carcinoma MGC-803 cells were demonstrated, and the molecular mechanisms underlying these effects are investigated. Our results indicate that AGC inhibited MGC-803 cell growth in a dose-dependent manner as measured by a 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay, with an $IC_{50}$ of about $6.045{\pm}0.69{\mu}g/mL$. In vivo, AGC inhibited growth of human gastric carcinoma in xenograft tumors in nude mice, and the inhibitory rate reached 55.2% at 300 mg/kg. The pro-apoptotic activity of AGC was attributed to its ability to decrease the expression of Bcl-2 and Pro-caspase3 and increase the expression of Bax. These results demonstrate that AGC can effectively induce programmed cell death and may be a promising anti-tumor drug in human gastric carcinoma.

Ligand-receptor clustering event is the most important step in leukocyte adhesion and spreading on endothelial cells. Intercellular adhesion molecule-1 (ICAM-1) has been shown to enhance leukocyte adhesion, but the molecular event during the process of adhesion is unclear. To visualize the dynamics of ICAM-1 movement during adhesion, we have engineered stable Chinese hamster ovary cell lines expressing ICAM-1 fused to a green fluorescent protein (IC1_GFP/CHO) and examined them under the fluorescence microscopy. The transfection of IC1_GFP alone in these cells was sufficient to support the adhesion of K562 cells that express $\alpha$L$\beta$2 (LFA-1) integrin stimulated by CBR LFA-1/2 mAb. This phenomenon was mediated by ICAM-1-LFA-1 interactions, as an mAb that specifically inhibits ICAM-1-LFA-1 interaction (RRl/l) completely abolished the adhesion of LFA-1＊ cells to IC1_ GFP/CHO cells. We found that the characteristic of adhesion was followed almost immediately (~10 min) by the rapid accumulation of ICAM-1 on CHO cells at a tight interface between the two cells. Interestingly, ICI_GFP/CHO cells projected plasma membrane and encircled approximately half surface of LFA-1+ cells, as defined by confocal microscopy. This unusual phenomenon was also confirmed on HUVEC after adhesion of LFA-1＊ cells. Neither cytochalasin D nor 2,3-butanedione 2-monoxime an inhibitor of myosin light chain kinase blocked LFA-1-mediated ICAM-1 clustering, indicating that actin cytoskeleton and myosin-dependent contractility are not necessary for ICAM-1 clustering. Taken together, we suggest that leukocyte adhesion to endothelial cells induces specialized form of ICAM-1 clustering that is distinct from immunological synapse mediated by T cell interaction with antigen presenting cells.
