  • Chungkookjang, fermented soybean, is high in microorganism, enzymes, daidzein, and peptides. Using yellow, black, Seoritae, small-black soybeans and Bacillus licheniformis B1, each Chungkookjang (YC, BC, SC, SBC) was prepared, and their fermentation patterns were compared. Changes of pH and browning material formation were taken as an indicative of fermentation. YC had a high pH increase at an early stage of fermentation, and a low change at a late stage. BC, SC, and SBC showed different patterns with a low pH increase at an early stage and a high pH increase at a late stage. Formation rate of browning material was fastest in YC and slow in the rest of BC, SC, and SMC. SC showed the highest value of browning material formation 1 d after fermentation. Anthocyanin in black soybeans seems to suppress the growth of bacteria at an early stage of fermentation. When anti-inflammatory daidzein contents were analyzed by HPLC, BC, SC, SBC showed higher values than YC. It was demonstrated that black soybeans can be fermented with B. licheniformis B1.

  • The increase in resistance by pathogenic bacteria to multiple antimicrobial agents has become a significant treat, as the effective antimicrobial agents available for the patients infected by such resistant bacteria are reduced, or even eliminated. Several natural plant extracts have exhibited antibacterial and synergistic activity against various resistant microorganisms. Houttuynia cordata is frequently used by many traditional medicine practicioners for its antimicrobial, antiviral, and anti-inflammatory properties. This study investigated the antibacterial effects of H. cordata extract against clinical multi-resistant bacteria, and compared the two methods used for the antimicrobial susceptibility testing. Thirty isolates of Methicillin-resistant Staphylococcus aureus (MRSA, 10), Vancomycin-resistant Enterococcus faecium (VRE, 10), Carbapenem-resistant Acinetobacter baumannii (CRAB, 10) were included in this study. The antibacterial effect of H. cordata was tested by disk diffusion and microbroth dilution methods as per CLSI guidelines. In disk diffusion, all isolates (30) showed no inhibition to 30,000 ug/mL of H. cordata. But in the microbroth dilution method, $MIC_{90}$ of H. cordata was 4,096 ug/mL, 8,192 ug/mL and 4,096 ug/mL in MRSA, VRE and CRAB, respectively. These results demonstrate that H. cordata exhibits antibacterial activity against MRSA, VRE and CRAB. Moreover, the microbroth dilution method is a more effective method than disk diffusion to evaluate the antibacterial activity of natural products. The Disk diffusion method used to evaluate the antibacterial activity of natural products required new standard guidelines including inoculum concentration of bacteria.

  • Bilirubin has an anti-inflammatory effect as an endogenous antioxidant and has been reported to be inversely correlated with hypertension, diabetes, metabolic syndrome, and insulin resistance. On the other hand, there is a lack of research evaluating the association between bilirubin and metabolic syndrome compared to liver-specific indicators. This study examined the association between the total bilirubin and metabolic syndrome prevalence in Korean adults who underwent health screening compared to ALT and GGT. This cross sectional study included 22,568 adult males and females aged 20 years or older who underwent a health examination at the General Hospital of Gyeonggi Province from March 2015 to February 2018. Metabolic syndrome was diagnosed based on the American Heart Association/National Heart, Lung, and Blood Institute (AHA/NHLBI) guidelines. In both genders, the metabolic syndrome diagnosed group had higher liver enzymes, and the total bilirubin and direct bilirubin were lower than those without the metabolic syndrome risk factors. The serum total bilirubin showed a weak inverse correlation with abdominal obesity (r=-0.066 vs r=-0.055) and triglyceride (r=-0.127 vs r=-0.136) in both males and females, which is weaker than ALT and GGT The data were statistically significant. In addition, total bilirubin as well as ALT and GGT in both men and women were not predictors of the likelihood of developing metabolic syndrome.

  • Cordycepin, an active component originally isolated from the traditional medicine Cordyceps militaris, is a derivative of the nucleoside adenosine, which has been shown to possess a number of pharmacological properties, including antioxidant and anti-inflammatory activities, immunological stimulation, and antitumor effects. This study was conducted on cultured human prostate carcinoma LNCap cells to elucidate the possible mechanisms by which cordycepin exerts its anticancer activity, which, until now, has remained poorly understood. Cordycepin treatment of LNCap cells resulted in dose-dependent inhibition of cell growth and the induction of apoptotic cell death as detected by an MTT assay, cleavage of poly ADP-ribose polymerase, and annexin V-FITC staining. Flow cytometric analysis revealed that cordycepin resulted in G2/M arrest in cell cycle progression and downregulation of cyclin B1 and cyclin A expression in a concentration-dependent manner. Moreover, the incubation of cells with cordycepin caused a striking induction in the expression of the cyclin-dependent kinase (CDK) inhibitor p21Waf1/Cip1 without affecting the expression of the tumor suppressor p53. It also resulted in a significant increase in the binding of CDK2 and CDC2 to p21. These findings suggest that cordycepin-induced G2/M arrest and apoptosis in human prostate carcinoma cells is mediated through p53-independent upregulation of the CDK inhibitor p21.

  • The purpose of this study was to evaluate the anti-atopic-dermatitis effect of Angelica keiskei extract using a DNFB-induced animal model of atopic-dermatitis symptoms. A. keiskei was prepared via extraction with DW, 50% ethanol, and 100% ethanol in addition to fresh juice. All the extracts reduced the thickness levels of the ears and ear epidermis against swelling by DNFB inducement, especially in the aqueous-extract-treated group. The mRNA expressions of matrix metalloproteinases (MMPs), however, were not observed, which may indicate that Angelica keiskei extract alleviates the atopic-dermatitis symptoms in an MMP-independent manner. Finally, the level of the inflammatory cytokine IL-4 was inhibited only in the juice-treated group, although the IL-13 level was inhibited in the juice-, 50%-ethanol-extract-, and 100%-ethanol-extract-treated groups in a dose-dependent manner, and was not inhibited in the aqueous-extract-treated group. Taken together, these results suggest that Angelica keiskei extract has an inhibitory effect on atopic dermatitis, and may be a useful biomaterial for the development of cosmeceuticals.

  • Background: Korean Red Ginseng (KRG) is a well-known natural product with anticarcinogenic and antioxidant effects. We evaluated the antifatigue effect of KRG in patients with nonalcoholic fatty liver disease (NAFLD). Methods: Eighty patients with NAFLD were prospectively randomized to receive 3 wk of KRG or placebo in addition to counseling on healthy eating and regular exercise. Liver function test, proinflammatory cytokines, adiponectin, antioxidant activity, and fatigue score were measured and compared according to the body mass index between the KRG and placebo groups. Results: The liver function tests were significantly improved after 3 wk of treatment in both groups. The mean levels (at baseline and after treatment) of tumor necrosis factor-${\alpha}$ were $108.0pg/mL{\pm}54.8pg/mL$ and $92.7pg/mL{\pm}39.0pg/mL$ (p = 0.018) in the KRG group and $123.1pg/mL{\pm}42.1pg/mL$ and $127.5pg/mL{\pm}62.2pg/mL$ (p = 0.694) in the placebo group, respectively. There was a significant difference in change of adiponectin levels between the KRG ($7,751.2pg/mL{\pm}3,108.1pg/mL$ and $8,197.3pg/mL{\pm}2,714.5pg/mL$) and placebo groups ($7,711.6pg/mL{\pm}3,041.3pg/mL$ and $7,286.1pg/mL{\pm}5,188.7pg/mL$, p = 0.027). In patients with overweight, the fatigue score was significantly decreased in the KRG group ($35.0{\pm}13.2$ and $24.5{\pm}8.9$, p = 0.019). Conclusion: Our results show that KRG might be effective in reducing proinflammatory cytokine and fatigue in overweight patients with NAFLD, in addition to improvements in adiponectin levels.

  • Purpose: This study was conducted to investigate the characteristics of drug induced anaphylactis and anaphylactic shock in patients who were admitted to the emergency department Methods: We retrospectively collected the data on patients with drug induced anaphylaxis and who were admitted to the emergency department from January 2001 to June 2009. The study group was divided into the non-shock and shock groups according to whether the systolic blood pressure more than 90mmHg. The initial demographic data, the causes of drug-induced anaphylaxis, the clinical manifestations, the treatment and the prognosis were reviewed for 72 patients. Results: The mean age of the study subjects was $47.9P{\pm}14.2$ years old and there were 40 male patients and 32 female patients. There were 26 patients in the non-shock group and 46 in the shock group. The mean age was older in the shock group than in the non-shock group ($51.5{\pm}15.1$ vs $42.5{\pm}10.6$, p-0.002). A history of drug allergy was more common in the shock group, but no difference was found for the comorbid chronic diseases between the two groups. Radio-contrast media was the most common cause, followed non-steroidal anti inflammatory drugs and antibiotics, but there is no difference in the causes between the two groups. The symptoms of cyanosis, syncope, sweating and dizziness were more frequently manifested in the shock group. The administration of intravenous fluid and injection of subcutaneous epinephrine at the emergency department were more frequent in the shock group than in the non-shock group. Conclusion: For the patients who were admitted to the emergency department with drug induced anaphylaxis, the mean age was older and the symptoms of cyanosis, syncope, sweating, dizziness were more frequent in the anaphylactic shock patients than in the non-shock group. More treatments were given at the emergency department to the anaphylactic shock patients.

  • Objectives: The aim of this study was to observe the reduction of lipid accumulation by treatment with Akkermansia muciniphila extract on 3T3-L1 adipocytes. Methods: After treating pasteurized Akk. muciniphila strains in HT-29 colorectal cancer cell, the relative expression of interleukin (IL)-8, tumor necrosis factor-α, IL-6, and IL-1β mRNA was analyzed by real time polymerase chain reaction, respectively. 27 strains of Akk. muciniphila which have anti-inflammatory effects were selected. 3T3-L1 pre-adipocytes were treated with Akk. muciniphila for 24 hr and then measured the toxicity using water soluble tetrazolium salt assay. The cells were incubated for 4 days and then differentiated into adipocytes using the medium including adipogenic reagents for 10 days. The Akk. muciniphila was treated when the medium was exchanged for differentiation medium at 4th day and insulin medium at 6th day. To observe the lipid accumulation, the cells were stained with Oil red O dye and were measured using a spectrophotometer. Results: In the cytotoxicity test, the cell viability of 3T3-L1 pre-adipocytes was significantly increased compared to the control group which untreated with Akk. muciniphila, and there was no cytotoxicity of Akk. muciniphila at 1×107 CFU/mL. The results on Oil red O staining and absorbance measurements were showed a significant decrease in lipid accumulation in the group which was treated with Akk. muciniphila compared to the control group. Conclusions: In our results, Akk. muciniphila has the inhibitory effect of lipid accumulation in 3T3-L1 adipocytes. This suggests that Akk. muciniphila could be help to improve obesity.

  • The multifaceted role of chronic inflammation in multistep carcinogenesis has been extensively investigated and well documented. Periodontal diseases are associated with multifactorial agents, including bacterial endotoxins and the generation of an inflammatory response, indicating that poor oral health is associated with a variety of systemic diseases. The association between poor oral health, chronic inflammation, smoking, and increased alcohol consumption as risk factors for tumorogenesis is well established. More recently, associations between oral health and tooth loss and gastric, lung, and pancreatic cancers have been explored, with some studies pointing to smoking and oral health as a common link with an increased risk for malignant disease. In addition, epidemiological studies consistently indicate increased risks of various cancers with periodontal disease or poor oral condition caused by oral bacteria, which may activate alcohol- and smoking-related carcinogens locally or act through chronic inflammation. Appropriate oral care is vital in preventing cancer, as well as many other diseases. Thus, research on the correlation between oral care and periodontal inflammation and cancer is required. This review highlights the association between oral health and the risk of certain malignancies, such as periodontal disease-associated chemoprevention of inflammation" in this sentence.

Differential Sensitivities of Human Multidrug-resistant Cancer Cells to BIIB021 and Modulation of Hsp90 Inhibitors by NSAIDs and Niclosamide (항암제 다제내성(MDR) 암세포의 Hsp90 저해제 BIIB021에 대한 감수성의 차이 및 NSAIDs 및 Niclosamide에 의한 Hsp90 저해제의 활성 변화)

  • The critical role of heat shock protein 90 (Hsp90) in tumorigenesis led to the development of several first- and second-generation Hsp90 inhibitors, which have demonstrated promising responses in cancers. In this study, we found second-generation Hsp90 inhibitor BIIB021-resistant multidrug-resistant (MDR) human cancer cells, although BIIB021 was shown to be active in first-generation Hsp90 inhibitor 17-allylamino-17-demethoxygeldanamycin (17-AAG)-resistant MDR cells. MCF7-MDR and HeyA8- MDR cells were more resistant to BIIB021 than their parental counterparts, indicating that BIIB021 cannot be applicable to all cancer cells expressing MDR proteins. We revealed that dimethyl-celecoxib (DMC), one of the non-steroidal anti-inflammatory drugs (NSAIDs), potentiated cytotoxicity of BIIB021 against both BIIB021-resistant and BIIB021-sensitive MDR cells. The effectiveness of NSAIDs involving celecoxib and DMC in combination with BIIB021 led to the autophagic degradation/down-regulation of mutant p53 (mutp53) that overexpressed MDR cells and the suppression of Hsp70 induction. This resulted in sensitization of MDR cells to BIIB021. Moreover, autophagy induction by sulindac sulfide, another type of NSAID, and niclosamide, an FDA-approved anthelmintic drug, potentiated 17-AAG-mediated autophagic degradation/down-regulation of mutp53 and c-Myc, client proteins of Hsp90. Therefore, our results suggest that NSAIDs and niclosamide positively enhance the anticancer activity of Hsp90 inhibitors through an autophagic pathway. They may also be new candidates for sensitizing MDR cells to Hsp90 inhibitors.
