  • The present study was to investigate anti-oxidative and anti-inflammatory activity of Perillae semen in RBL-2H3 basophilic leukemia cells. Inhibitory effect of Perillae semen onto free radical generation was determined by measuring DPPH and hydroxyl radical scavenging activities in vitro. Anti-inflammatory actions of Perillae semen extracts (100, 250, $500\;{\mu}g/mL$) were assessed by testing their effects on the degranulation of mast cells. For this, $\beta$-hexosaminidase released from RBL-2H3 cells was used and proinflammatory cytokines were measured by an ELISA kit. Our results indicated that Perillae semen water extracts effectively inhibited free radical generation. At the concentration of $500\;{\mu}g/mL$ of water extract, the degranulation of RBL-2H3 cells were inhibited by 42.1%. The IgE-antigen complex increased the accumulation of IL-4 and TNF-$\alpha$ secretion in RBL-2H3 cells and treatments with 250 and $500\;{\mu}g/mL$ of Perillae semen extracts suppressed the IgE induced secretion of IL-4 and TNF-$\alpha$ protein by 20.5, 26.9% and 14.5, 16.5% respectively. We observed that Perillae semen water extract reduced $\beta$-hexosaminidase, IL-4, and TNF-$\alpha$ secretion in RBL-2H3 cells. These results provide that Perillae semen may be beneficial in the treatment of allergic inflammatory disease.

  • Purpose: Advanced cancer may accompany cold sweat as paraneoplastic symptom. Few studies have been performed on the efficacy of non-steroid anti-inflammatory drug (NSAID) in advanced cancer patients who sweated without fever. Methods: To select study participants, medical records were retrospectively reviewed for patients who satisfied the following criteria: 1) incurable, advanced solid cancer; 2) Cold sweating of 4 or higher on the numeric rating scale (NRS) 4; 3) No evidence of infection or hypoglycemia; 4) No newly started opioid or anti-hormonal agents within one month; 5) NSAID prescription for the management of cold sweating and 6) Documented NRS information before and after NSAID administration. Results: A total of 13 patients were selected after excluding four patients due to lack of NRS information or fever. The mean age was 59 years old (range: 50~71), and nine patients (69%) were male. Bile duct cancer was the most common primary tumor followed by pancreatic cancer, gastric cancer and prostate cancer. The mean NRS of cold sweating dropped from baseline 6.5 (min-max: 4~10) to 1.9 at the follow-up assessment (min-max: 0~5). The mean follow-up period was 9.1 days (range: 2~30 days) from NSAID treatment to assessment. Conclusion: NSAID was effective medication for management of sweating without fever in patients with advanced cancer.

  • The resistance of cancer cells to anti-cancer drugs is the leading cause of chemotherapy failure. The clinical use of nonsteroidal anti-inflammatory drugs (NSAIDs) has been gradually extended to cancer treatment through combination with anti-cancer drugs. In the current study, we investigated whether NSAIDs including celecoxib (CCB), 2,5-dimethyl celecoxib (DMC), and ibuprofen (IBU) could enhance the cytotoxic effects of imatinib and TNF-related apoptosis inducing ligand (TRAIL) on human cancer cells. We found that the NSAIDs potentiated TRAIL and imatinib cytotoxicity against human hepatocellular carcinoma (HCC) cell lines SNU-354, SNU-423, SNU-449, and SNU-475/TR and against leukemic K562 cells with high level of CD44 (CD44highK562), respectively. More specifically, CCB induced endoplasmic reticulum stress via up-regulation of ATF4/CHOP which is associated with the induction of autophagy against HCC and CD44high K562 cells. NSAID-induced autophagic activity accelerated TRAIL cytotoxicity of HCC cells through up- and down-regulation of DR5 and c-FLIP, respectively. The NSAIDs also potentiated imatinib-induced cytotoxicity and apoptosis through down-regulation of markers in CD44highK562 cells that express a stemness phenotype. Our results suggest that the ability of NSAIDs to induce autophagy could enhance the cytotoxicity of TRAIL and imatinib, leading to a reverse resistance to these drugs in the cancer cells. In conclusion, NSAIDs in combination with low-dose TRAIL or imatinib may constitute a novel clinical strategy that maximizes therapeutic efficacy of each drug and effectively reduces the toxic side effects.

  • Bacterial resistance to antibiotics and residues of antibiotics in poultry products have encouraged the use of probiotics, prebiotic substrates, and synbiotic combinations of prebiotics and probiotics as alternative approaches to the use of antibiotics in poultry. The present study was carried out to evaluate the effect of a new probiotic CS61 culture on growth performance, feed conversion efficiency, and safety in broiler chickens, and to evaluate its value as an alternative for antibiotics used as a feed additive. Two dosages of CS61 culture (0.1% and 1%) were fed to chickens for 28 days. The results showed that terminal body weight and daily weight gain in the treatment groups increased in a dose-dependent manner when compared with the control group. Dietary supplementation with CS61 culture also improved feed conversion rate compared to the control group. There were no treatment-related toxic effects in terms of clinical findings, mortality, necropsy findings, hematology, or serum biochemistry parameters in any group tested. The nitric oxide assay showed that CS61 peptide has a dose-dependent inhibitory effect on lipopolysaccharide-induced nitric oxide production in RAW 264.7 cells. The results of this experiment indicated that dietary supplementation of CS61 culture may improve growth performance and feed conversion efficiency in chickens through its anti-inflammatory effect.

  • Background: Luteolin, a flavone found in various Chinese herbal medicines is known to possess anti-inflammatory properties through its ability to inhibit various proinflammatory signaling pathways including NF-${\kappa}B$ and p38 MAPK. In this study, we investigated the potential therapeutic effect of luteolin on dextran sodium sulfate (DSS)-induced colitis. Materials and Methods: We used a transgenic mouse model expressing the enhanced green fluorescent protein (EGFP) under the transcriptional control of NF-${\kappa}B$ $cis$-elements. C57BL/6 NF-${\kappa}B^{EGFP}$ mice received 2.5% DSS in their drinking water for six days in combination with daily luteolin administration (1mg/kg body weight, 0.1ml vol, intragastric) or vehicle. NF-${\kappa}B$ activity was assessed macroscopically with a Charge-Coupled Device (CCD) camera and microscopically by confocal analysis. Results: A significant increase in the Disease Activity Index (DAI), histological score (p<0.05), IL-12 p40 secretion in colonic stripe culture (p<0.05) and EGFP expression was observed in luteolin and/or DSS-treated mice compared to water-treated mice. Interestingly, a trend toward a worse colitis (DAI, IL-12p40) was observed in luteolin-treated mice compared to non-treated DSS-exposed mice. In addition, EGFP expression (NF-${\kappa}B$ activity) strongly increased in the luteolin-treated mice compared to control mice. Confocal microscopy showed that EGFP positive cells were primarily lamina propria immune cells. Conclusions: These results suggest that luteolin is not a therapeutic alternative for intestinal inflammatory disorders derived for primary defects in barrier function. Thus, therapeutic intervention targeting these signaling pathways should be viewed with caution.

  • Objective: The prevalence rate of osteoarthritis in Koreans aged 50 years or older is 14.3%, and the total amount of medical costs is more than KRW 1 trillion. Recently, the reimbursement guidelines for osteoarthritis treatment have changed. Methods: In this study, we sought to describe prescription patterns of nonsteroidal anti-inflammatory drugs (NSAIDs) and gastro-protective agent (GPA) and analyze the clinical and economic impacts of the new policy using the national health insurance claims data. The incidence of upper gastrointestinal adverse event by policy change was identified through the odds ratio, and changes in medicine and medical costs related to osteoarthritis through mean and median. Results: There were 204,552 patients before the reimbursement guidelines relaxation and 239,710 after it, a 17.2% rise. The prescription ratio was 3.3% for the patients prescribed with COX-2 selective NSAIDs alone and 1.3% for those with both COX-2 selective NSAIDs and GPA combination before the reimbursement guidelines relaxation. The reimbursement guidelines relaxation significantly increased their ratios to 6.9% and 2.8%, respectively. Gastrointestinal adverse events significantly reduced by 1.21%p after reimbursement guidelines relaxation. The average medicine cost per person increased significantly to KRW 140,291 from KRW 137,323 after the reimbursement guidelines relaxation, while the average medical cost per person slightly decreased from KRW 311,605 to KRW 310,755 after the relaxation, showing no meaningful difference. Conclusion: The reimbursement guidelines relaxation may influence on decreasing the upper gastrointestinal adverse event, increasing the medicine costs and maintaining the medical costs for osteoarthritis.

  • This study confirmed the effects of improving lung damage of celecoxib using an animal model of chronic obstructive pulmonary disease(COPD). It was induced in models LPS + CSE and performed in vitro and in vivo. MTT assay and real-time PCR were performed in MRC5 cells as in vitro, and mRNA expression, BALF, collagen content, and protein expression were confirmed as in vivo. Celecoxib reduced the number of inflammatory cells, cytokine and soluble protein accumulation in BALF, decreased body weight and lung weight in animal models, and improved lung collagen deposition. In addition, the reduction of EMT markers was confirmed through Western blotting and real-time PCR. Consequently, celecoxib is thought to improve lung damage of COPD induced to LPS+CSE by regulating EMT.

  • Coprinellus micaceus, belongs to family Psathyrellaceae of Agaricales, Basidiomycota, has been used for edible purposes in the world. This study was initiated to evaluate the antioxidant, anti-diabetic, anti-cholinesterase, anti-tyrosinase, and nitric oxide inhibitory activities of fruiting bodies from C. micaceus extracted with methanol and hot water. The HPLC analysis of phenolic compounds from the mushroom extracts identified 4 phenolic compounds including procatechuic acid, chlorogenic acid, (-)-epicatechin, and naringin. In 1,1-diphenyl-2-picrylhydrazyl(DPPH) free radical scavenging assay, the scavenging activities of methanol and hot water extracts were lower than that of positive control, BHT. The chelating effects of methanol and hot water extracts were significantly higher than that of BHT, the positive control at the all concentrations tested. In the reducing power assay, methanol and hot water extracts exhibited the lower activities compared with positive control at the 0.125-0.2 mg/ml. The methanol and hot water extracts of the mushroom inhibited the ${\alpha}$-glucosidase activity by 62.26% and 67.59%, respectively at the 2.0 mg/ml, while acarbose, the positive control, inhibited the ${\alpha}$-glucosidase activity by 81.81% at the same concentration. In the acetylcholinesterase(AChE) inhibitory activity assay, methanol and hot water extracts of the mushroom inhibited the AChE by 94.64% and 74.19%, respectively at 1.0 mg/ml, whereas the galanthamine, standard drug, inhibited the AChE activity by 97.80% at the same concentration. The tyrosinase inhibitory activities of methanol and hot water extracts were 91.33% and 91.99% at 2.0 mg/ml, while the inhibitory activity of kojic acid, the positive control, was 99.61% at the same concentration. Nitric oxide(NO) production in lipopolysaccahride (LPS) activated RAW 264.7 cells were inhibited by the methanol and hot water extracts in a concentration dependent manner. Therefore, it is concluded that fruiting bodies of C. micaceus contained natural antioxidant, anti-acetylcholinesterase and ${\alpha}$-glucosidase inhibitory, anti-inflammatory, anti-tyrosinase substances which might be used for promoting human health.

  • 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.

  • Background : It is known that airway inflammation is present in most patients with asthma, but the relationship between symptoms and the severity and nature of airway inflammation has not been established. Cough variant asthma is defined as an asthma in which the dominant symptom is cough, and the condition can be successfully treated with inhaled steroids. This study was performed to evaluate the time course of bronchial responsiveness according to an inhaled anti-inflammatory therapy and the factors which affect the resolution of bronchial responsiveness, and an efficacy of nedocromil to cough asthma. Method: A prospective study for the investigation of bronchial responsiveness according to an inhaled anti-inflammatory treatment in sixty-one cough asthmatics was performed. Twenty-three entered budesonide ($400{\mu}g{\times}2/day$), twenty-two entered nedocromil ($4mg{\times}2/day$) and sixteen patients entered combined group. The bronchial hyperresponsiveness (BHR) was estimated by methacholine challenge test using counted breath method. The symptom was estimated by 'symptom score'. Reevaluation of BHR and symptom was performed at 2 month after treatment, and if BHR was not resoluted at this time, regarded as a non-responder, and then follow-up of BHR and symptom was performed at 4- and/or 6 month after treatment. Results: The improvement of BHR and symptom was significant in 2 month (p<0.05), but there was no change of them during follow-up period of 4- and/or 6 month in non-responders. In comparison of allergic markers such as serum total IgE, peripheral eosinophil count and skin test reactivity between responders and non-responders, there was no difference in each other. However, in comparison of other factors such as cumulative pack-years, symptom duration, age, gender, and the initial degree of PC20, there was a significant difference in each other(p<0.05). The percent of patients with the resolution of BHR in 2 month was not different in each group(p=0.95). There was no significant difference in the degree of improvement of BHR and symptom in each group. Conclusion: Bronchial responsiveness and symptom was not significantly improved in non-responders during follow-up period of 4- and/or 6 month. The effect of inhaled nedocromil was equivalent to that of inhaled steroid in cough asthmatics, and the response to combined treatment is not superior to that achieved by either of these agents used alone.
