Rebamipide is a mucosal-protective antiulcer drug, but its mechanism of action in gastric cancer remains elusive. CagA, a major virulence factor of Helicobacter pylori (H. pylori), is associated with the risk of gastric cancer. CagA protein is injected into gastric epithelial cells and deregulates a variety of cellular signaling molecules. CagA from H. pylori induces phospholipase D1 (PLD1) expression through NFκB activation in gastric epithelial cells, followed by invasion and proliferation of gastric epithelial cancer cells. Infection with cagA-positive H. pylori and expression of CagA enhances the binding of NFκB to the PLD1 promoter. Rebamipide abolishes H. pylori cagA-induced PLD1 expression via inhibition of binding of NFκB to the PLD1 promoter and also inhibits PLD activity. Moreover, rebamipide abolishes H. pylori CagA-induced β-catenin and the expression of a target cancer stem cell (CSC) marker gene via upregulation of miRNA-320a and -4496, followed by attenuation of self-renewal capacity of H. pylori CagA-infected gastric CSCs. In addition, rebamipide increases the chemosensitivity of CagA-expressed gastric CSCs and suppresses gastric carcinogenesis. Thus, it is speculated that rebamipide might show a potent efficacy as chemotherapeutic drug against gastric cancer cells. In this review, we summarizes recent results regarding the novel insights for the efficacy of rebamipide in gastric cancer cells.

Objectives : The present study was conducted to examine whether Cynanchi wilfordii radix (CWR) with or without fermentation has an ameliorative effect on hyperlipidemia in rats.Methods : We analyzed the contents of Conduritol F on Cynanchi wilfordii radix. The experimental animals were divided into six groups; normal diet fed group (N), high cholesterol fed control group (Con), Lovastatin 20 mg/kg (L), CWR-W 300 mg/kg (CWR-W), and CWR-F 300 mg/kg on hyperlipidemia model induced by feeding 1.25% cholesterol. Rats were administrated orally every day for 8 weeks. And lipid profile of serum and weight change were observed.Results : The vehicle displayed a markedly increased body weight and significantly increased liver and epididymal fat weight, however, the administration of CWR improved the body, liver, and epididymal fat weights. All drug treatment reduced significantly the serum level of total cholesterol and LDL-cholesterol elevated by intake of high cholesterol diet. TG displayed a reducing tendency all drug treatment, however, CWR-W decreased significantly. Atherogenic index and cardiac risk factor increased high cholesterol diet fed control group, while the administration of CWR-W and CWR-F decreased significantly. The major index of liver injury such as AST and ALT improved in all drug treatment.Conclusions : These results suggest that CWR extended the effect of lipid enhanced. Therefore CWR with or without fermentation may be useful for therapeutic treatment of clinical conditions associated with hyperlipidemia. Finally, these require more investigations about the action mechanism of CWR in the future.

Hepatocellular carcinoma is the world's most common primary malignant tumor of the liver. In-Jin-ho-Tang (IJHT) has been used as a traditional Chinese herbal medicine since ancient times, and today it is widely used as a medication for jaundice associated with inflammation of the liver. In-Jin-Ho-Tang is a drug preparation consisting of three herbs: Artemisiae Capillaris Herba (Artemisia capillaries $T_{HUNS}$, Injinho in Korean), Gardeniae Fructus (Gardenia jasminodes $E_{LLIS}$, Chija in Korean) and Rhei radix et rhizoma (Rheum palmatum L., Daehwang in Korean). This study investigated whether or not methanol extract of IJHT could induce HepG2 cancer cell death. Cytotoxic activity of IJHT on HepG2 cells was measured using an XTT assay, with an $IC_{50}$ value of $700{\mu}g/ml$ at 24 h Apoptosis induction by IJHT in HepG2 cells was verified by the cleavage of poly ADP-ribose polymerase, and a decrease in procaspase-3, -8, -9. Treatment of IJHT resulted in the release of cytochrome c into cytosol, loss of mitochondrial membrane potential (${\Delta}{\Psi}_m$), decrease in anti-apoptotic Bcl-2, and an increase in pro-apoptotic Bax expression. Thus, IJHT induced apoptosis in HepG2 cells via activation of caspase and mitochondria pathway. These results indicate that IJHT has potential as an anti-cancer agent.

$\beta$-Glucans have been known to exhibit antitumor activities by potentiating host immunity by an unknown mechanism. The C-type lectin dectin-1, a $\beta$-glucan receptor, is found on the macrophage and can recognize various $\beta$-glucans. Previously, we demonstrated the presence of $\beta$-glucan receptor, dectin-1, on the Raw 264.7 cells as well as on murine mucosal organs, such as the thymus, the lung, and the spleen. In order to investigate immunopotentiation of innate immunity by $\beta$-glucan, we stimulated a murine macrophage Raw 264.7 cell line with $\beta$-glucans from Pleurotus ostreatus, Saccharomyces cerevisiae, and Laminaria digitata. Then, we analyzed cytokines such as tumor necrosis factor (TNF)-$\alpha$ and interleukin (IL)-6 by reverse transcription-polymerase chain reaction (RT-PCR). In addition we analyzed gene expression patterns in $\beta$-glucan-treated Raw 264.7 cells by applying total mRNA to cDNA microarray to investigate the expression of 7,000 known genes. When stimulated with $\beta$-glucans, the macrophage cells increased TNF-$\alpha$ expression. When co-stimulation of the cells with $\beta$-glucan and lipopolysaccharide (LPS), a synergy effect was observed by increased TNF-$\alpha$ expression. In IL-6 expression, any of the $\beta$-glucans tested could not induce IL-6 expression by itself. However, when co-stimulation occurred with $\beta$-glucan and LPS, the cells showed strong synergistic effects by increased IL-6 expression. Chip analysis showed that $\beta$-glucan of P. ostreatus increased gene expressions of immunomodulating gene families such as kinases, lectin associated genes and TNF-related genes in the macrophage cell line. Induction of TNF receptor expression by FACS analysis was synergized only when co-stimulated with $\beta$-glucan and LPS, not with $\beta$-glucan alone. From these data, $\beta$-glucan increased expressions of immunomodulating genes and showed synergistic effect with LPS.

The multidrug resistance protein 2 (MRP2, ABCC2) gene may determine individual susceptibility to adverse drug reactions (ADRs) in the central nervous system (CNS) by limiting brain access of antiepileptic drugs, especially valproic acid (VPA). Our objective was to investigate the effect of ABCC2 polymorphisms on ADRs caused by VPA in Korean epileptic patients. We examined the association of ABCC2 single-nucleotide polymorphisms and haplotype frequencies with VPA related to adverse reactions. In addition, the association of the polymorphisms with the risk of VPA related to adverse reactions was estimated by logistic regression analysis. A total of 41 (24.4%) patients had shown VPA-related adverse reactions in CNS, and the most frequent symptom was tremor (78.0%). The patients with CNS ADRs were more likely to have the G allele (79.3% vs. 62.7%, p=0.0057) and the GG genotype (61.0% vs. 39.7%, p=0.019) at the g.-1774delG locus. The frequency of the haplotype containing g.-1774Gdel was significantly lower in the patients with CNS ADRs than without CNS ADRs (15.8% vs. 32.3%, p=0.0039). Lastly, in the multivariate logistic regression analysis, the presence of the GG genotype at the g.-1774delG locus was identified as a stronger risk factor for VPA related to ADRs (odds ratio, 8.53; 95% confidence interval, 1.04 to 70.17). We demonstrated that ABCC2 polymorphisms may influence VPA-related ADRs. The results above suggest the possible usefulness of ABCC2 gene polymorphisms as a marker for predicting response to VPA-related ADRs.

Background: The increasing prevalence of drug-resistant tuberculosis (TB) infection represents a global public health emergency. We evaluated the usefulness of a newly developed multiplexed, bead-based bioassay (Quantamatrix Multiplexed Assay Platform [QMAP], QuantaMatrix, Seoul, Korea) to rapidly identify the Mycobacterium tuberculosis complex (MTBC) and detect rifampicin (RIF) and isoniazid (INH) resistance-associated mutations. Methods: A total of 200 clinical isolates from respiratory samples were used. Phenotypic anti-TB drug susceptibility testing (DST) results were compared with those of the QMAP system, reverse blot hybridization (REBA) MTB-MDR assay, and gene sequencing analysis. Results: Compared with the phenotypic DST results, the sensitivity and specificity of the QMAP system were 96.4% (106/110; 95% confidence interval [CI] 0.9072-0.9888) and 80.0% (72/90; 95% CI 0.7052-0.8705), respectively, for RIF resistance and 75.0% (108/144; 95% CI 0.6731-0.8139) and 96.4% (54/56; 95% CI 0.8718-0.9972), respectively, for INH resistance. The agreement rates between the QMAP system and REBA MTB-MDR assay for RIF and INH resistance detection were 97.6% (121/124; 95% CI 0.9282-0.9949) and 99.1% (109/110; 95% CI 0.9453-1.0000), respectively. Comparison between the QMAP system and gene sequencing analysis showed an overall agreement of 100% for RIF resistance (110/110; 95% CI 0.9711-1.0000) and INH resistance (124/124; 95% CI 0.9743-1.0000). Conclusions: The QMAP system may serve as a useful screening method for identifying and accurately discriminating MTBC from non-tuberculous mycobacteria, as well as determining RIF- and INH-resistant MTB strains.

This study is a descriptive investigation study to identify the Convergence factors of the subjective health status, communication with medical personnel and drug misuse on medication adherence. The subjects of this study were 179 senior citizens who used community elderly welfare centers. Data were collected from January 13, 2020 to January 17, 2020. Data analysis was performed using frequency, percentage, mean, standard deviation, t-test, ANOVA. Post-Hoc Test Was performed using Scheffe test, Pearson's correlation coefficients and multiple regression analysis. The regression equation of this study explained 24% of medication adherence. Drug misuse(𝛽=-4.32, p=<.001) was the factor that had the greatest influence on the medication adherence, followed by the presence or absence of chronic disease (𝛽=-3.04, p=.003), marital status (𝛽=2.64, p=.009), and communication with medical personnel (𝛽=2.26, p=.025 ) in that order. Therefore, it is necessary to establish a convergence system of medication adherence for the elderly using community welfare centers.

Nonprescription drugs have become increasingly important in Korean healthcare. By leveraging lower-cost drugs and reducing expenditure associated with fewer physician visits, the nonprescription segment can deliver tremendous value to individual consumers and the Korean healthcare system. Many countries have provided simpler and more rapid routes to market entry for qualifying nonprescription drug products, using the established data on drug safety and efficacy, as well as public and professional opinion. In US, the FDA waived the pre-approval process for over-the-counter (OTC) drugs marketed through the OTC Monograph Process. In Australia and Canada, different OTC product application levels are defined, with a reduced level of assessment required when the risks to consumers are considered low. Japan established a new OTC evaluation system in 2014 to facilitate the Rx-to-OTC switch process. The legislative framework for medicinal products in the European Union allows for drugs to be approved with reference to appropriate bibliographic data for old active substances with well-established uses. Through a comparison of the regulatory framework and the requirements for nonprescription approval process in different countries, several ways to improve regulatory practice for the evaluation of nonprescription drugs in Korea have been suggested.

Oseltamivir is an antiviral medication prescribed to prevent and treat influenza A and B. A case from a community pharmacy in Korea was reported for an adverse event associated with oseltamivir administration. A 20-month-old boy had psychiatric symptoms after receiving 2 doses of oseltamivir. Therefore, an evaluation of whether the psychiatric symptoms were caused by oseltamivir was required. To determine whether the adverse event resulted from the administrated medication or other factors, three tools were used: the Naranjo scale, the Korean causality assessment algorithm (Ver.2), and the World Health Organization-Uppsala Monitoring Center (WHO-UMC) criteria. The psychiatric symptoms occurred after oseltamivir administration, and were attenuated after oseltamivir termination. A possible cause of the psychiatric symptoms is high fever, but information on the body temperature of the patient was not sufficient. Therefore, it was unclear whether there were other nonpharmacological causes of adverse drug reaction. For these reasons, in terms of causality, the results evaluated by the three tools represented, "possible", "probable", and "probable/likely", respectively.
