Objective : This study was performed to estimate the effects of OMC-2010 extract on cytokine production in mouse spleen cells. Methods : Mouse spleen cells were pre-treated with ethanol and water extract of OMC-2010 for 1 h, then stimulated with lipopolysaccharide (LPS, 1 μg/ml) for 48 h. Then the cells were harvested for real-time reverse transcription polymerase chain reaction to detect cytokines. Results : OMC-2010 ethanol extract significantly inhibited the LPS-induced interleukin (IL)-1beta, tumor necrosis factor (TNF)-alpha and IL-5 mRNA expressions, but not shown such changes in IL-6, IL-4, IL-13. OMC-2010 water extract significantly inhibited the LPS-induced TNF-alpha, and IL-5 mRNA expressions, but not shown such changes in IL-1beta, IL-6, IL-4, IL-13. Conclusions : Theses results could suggest that both ethanol and water OMC-2010 extract could inhibit the TNF-alpha and IL-5 mRNA expression.

(Young Il I . Koh),(In Seon S . Choi),(Won Young Kim),(Hyun Chul Lee),(Jong Un Lee) 대한내과학회 2001 The Korean Journal of Internal Medicine Vol.16 No.3

N/A Background: BCG, a potent inducer of Th1 immune response, has been suggested to suppress Th2 response which is known to mediate IgE-mediated allergic disorders, in particular allergic asthma. Schultz-Dale reaction is known to be a model of IgE-mediated hypersensitivity. This study was done to investigate whether BCG infection suppresses the Schultz-Dale reaction by inhibiting Th2 response and allergen-specific IgE production. Methods: Twenty-four Sprague-Dawley rats were sensitized and provoked with ovalbumin (OVA). A pretreatment of 6×104 colony forming units of BCG or saline was done 7 days before sensitization. The Schultz-Dale reaction was represented as tracheal smooth muscle contractions to 50μg/mL OVA challenge in vitro. Serum OVA-specific IgE levels and IFN-γand IL-4 concentrations in bronchoalveolar lavage fluid (BALF) were measured. Results: The Schultz-Dale reaction and serum OVA-specific IgE levels were significantly decreased in BCG infected and OVA sensitized rats compared with only sensitized rats (p<0.01 and p<0.05, respectively). As compared with only sensitized rats, IL-4 concentration and a ratio of IFN-γ:IL-4 in BCG infected and OVA sensitized rats were significantly decreased (p<0.001) and increased (p<0.05), respectively. The Schultz-Dale reaction was correlated with OVA-specific IgE levels (r=0.50, p<0.05), IL-4 concentration (r=0.69, p<0.001), and ratio of IFN-:IL-4(r=-0.44, p<0.05). OVA-specific IgE levels were correlated with IL-4 concentration (r=0.61, p<0.01) and ratio of IFN-γ:IL-4(r=-0.48, p<0.05). Conclusion: These findings suggest that BCG infection prior to allergen sensitization may inhibit Schultz-Dale reaction developed in the sensitized rat tracheal smooth muscle via the suppressive effects of Th2 immune response and allergen-specific IgE production.

Triptolide suppresses interleukin-1beta-induced human beta-defensin-2 mRNA expression through inhibition of transcriptional activation of NF-kappaB in A549 cells.

Jang, Byeong-Churl,Lim, Ki-Jo,Choi, In-Hak,Suh, Min-Ho,Park, Jong-Gu,Mun, Kyo-Chul,Bae, Jae-Hoon,Shin, Dong-Hoon,Suh, Seong-Il D.A. Spandidos 2007 INTERNATIONAL JOURNAL OF MOLECULAR MEDICINE Vol.19 No.5

<P>The immunosuppressive effect of triptolide has been associated with suppression of T-cell activation. However, the immunosuppressive effects of triptolide on innate immunity in the epithelial barrier remain to be elucidated. Human beta-defensin (HBD)-2 is an inducible antimicrobial peptide and plays an important role in the innate immunity. We have previously demonstrated that IL-1beta induced HBD-2 mRNA expression in A549 cells through activation of nuclear factor-kappaB (NF-kappaB) transcriptional factor as well as p38 mitogen-activated protein kinase (MAPK), c-Jun N-terminal kinase (JNK), or phosphatidylinositol-3-kinase (PI3K). In this study, we investigated effects of triptolide on IL-1beta-induced HBD-2 mRNA expression in A549 cells. Triptolide inhibited IL-1beta-induced HBD-2 mRNA expression in a dose-dependent manner. Addition of triptolide did not suppress activation of p38 MAPK, JNK, or PI3K in response to IL-1beta. Triptolide inhibited IL-1beta-induced MAPK phosphatase-1 expression at the transcriptional level and resulted in sustained phosphorylation of JNK or p38 MAPK, explaining the little effect of triptolide on IL-1beta-induced phosphorylation of these kinases. Although triptolide partially suppressed IL-1beta-mediated degradation of IkappaB-alpha and nuclear translocation of p65 NF-kappaB, triptolide potently inhibited NF-kappaB promoter-driven luciferase activity in A549 cells. These results collectively suggest that the inhibitory effect of triptolide on IL-1beta-induced HBD-2 mRNA expression in A549 cells seems to be at least in part mediated through nuclear inhibition of NF-kappaB transcriptional activity, but not inhibition of p38 MAPK, JNK, or PI3K. This inhibition may explain the ability of triptolide to diminish innate immune response.</P>

<i>In vivo</i> genotoxicity evaluation of lung cells from Fischer 344 rats following 28 days of inhalation exposure to MWCNTs, plus 28 days and 90 days post-exposure

Kim, Jin Sik,Sung, Jae Hyuck,Choi, Byung Gil,Ryu, Hyeon Yeol,Song, Kyung Seuk,Shin, Jae Hoon,Lee, Jong Seong,Hwang, Joo Hwan,Lee, Ji Hyun,Lee, Gun Ho,Jeon, Kisoo,Ahn, Kang Ho,Yu, Il Je Informa Healthcare 2014 INHALATION TOXICOLOGY Vol. No.

<P>Despite their useful physico-chemical properties, carbon nanotubes (CNTs) continue to cause concern over occupational and human health due to their structural similarity to asbestos. Thus, to evaluate the toxic and genotoxic effect of multi-wall carbon nanotubes (MWCNTs) on lung cells <I>in vivo</I>, eight-week-old rats were divided into four groups (each group = 25 animals), a fresh air control (0 mg/m<SUP>3</SUP>), low (0.17 mg/m<SUP>3</SUP>), middle (0.49 mg/m<SUP>3</SUP>), and high (0.96 mg/m<SUP>3</SUP>) dose group, and exposed to MWCNTs <I>via</I> nose-only inhalation 6 h per day, 5 days per week for 28 days. The count median length and geometric standard deviation for the MWCNTs determined by TEM were 330.18 and 1.72 nm, respectively, and the MWCNT diameters ranged from 10 to 15 nm. Lung cells were isolated from five male and five female rats in each group on day 0, day 28 (only from males) and day 90 following the 28-day exposure. The total number of animals used was 15 male and 10 female rats for each concentration group. To determine the genotoxicity of the MWCNTs, a single cell gel electrophoresis assay (Comet assay) was conducted on the rat lung cells. As a result of the exposure, the olive tail moments were found to be significantly higher (<I>p</I> < 0.05) in the male and female rats from all the exposed groups when compared with the fresh air control. In addition, the high-dose exposed male and middle and high-dose exposed female rats retained DNA damage, even 90 days post-exposure (<I>p</I> < 0.05). To investigate the mode of genotoxicity, the intracellular reactive oxygen species (ROS) levels and inflammatory cytokine levels (TNF-α, TGF- β, IL-1, IL-2, IL-4, IL-5, IL-10, IL-12 and IFN-γ) were also measured. For the male rats, the H<SUB>2</SUB>O<SUB>2</SUB> levels were significantly higher in the middle (0 days post-exposure) and high- (0 days and 28 days post-exposure) dose groups (<I>p</I> < 0.05). Conversely, the female rats showed no changes in the H<SUB>2</SUB>O<SUB>2</SUB> levels. The inflammatory cytokine levels in the bronchoalveolar lavage (BAL) fluid did not show any statistically significant difference. Interestingly, the short-length MWCNTs deposited in the lung cells were persistent at 90 days post-exposure. Thus, exposing lung cells to MWCNTs with a short tube length may induce genotoxicity.</P>

CHOI, SUN-IL,JUNG, TAE-DONG,CHO, BONG-YEON,CHOI, SEUNG-HYUN,SIM, WAN-SUP,HAN, XIONGGAO,LEE, SANG JONG,KIM, YOUNG-CHEUL,LEE, OK-HWAN UNKNOWN 2019 INTERNATIONAL JOURNAL OF MOLECULAR MEDICINE Vol.44 No.2

<P> Processed products from agricultural produce generate a large number of agricultural by-products that contain a number of functional substances. These are often discarded owing to the lack of suitable processing methods. The present study investigated the anti-photoaging properties of fermented rice bran (FRB), soybean cake (FSB) and sesame seed cake (FSC) on ultraviolet B (UVB)-irradiated hairless mouse skin. Results indicated that the oral administration of FRB, FSB and FSC effectively inhibited the UVB irradiation-induced expression of matrix metalloproteinase (MMP)-2, MMP-9, MMP-3 and MMP-13. Reverse transcription-quantitative polymerase chain reaction results also demonstrated that FRB, FSB and FSC significantly inhibited the UVB-induced expression of the genes encoding tumor necrosis factor-α, inducible nitric oxide synthase, interleukin (IL)-6 and IL-1β when compared with the UVB-vehicle group (P<0.05). Additionally, collagen degradation and mast cell infiltration were reduced in hairless mouse skin. Furthermore, UVB-induced wrinkle formation was also significantly reduced in mouse skin compared with the UVB-vehicle group (P<0.05). These results reveal that fermented agricultural by-products may serve as potential functional materials with anti-photoaging activities. </P>

Choi, Gi Soon,Han, Jae Bok,Park, Joon Ha,Oh, Sang Deog,Lee, Gi Seog,Bae, Hyun Su,Jung, Sung Ki,Cho, Young Wuk,Ahn, Hyun Jong,Min, Byung Il WHO COLLABORATING CENTRE FOR TRADITIONAL MEDICINE 2004 東西醫學硏究所 論文集 Vol.2004 No.-

Moxibustion is one of the major healing techniques in Oriental medicine. It has been widely used in many diseases such as rheumatoid arthritis, Hashimoto disease, breech presentation, etc. However, till now, effects of moxibustion on natural killer (NK) cell activity and relations between sympathetic nerve system (SNS) and the immune alteration induced by moxibustion wert not well studied. This study was designed to evaluate effects of moxibustion on NK cell activity and the Intervention of SNS in the alteration of NK cell activity induced by moxibustion. Splenic NK cell cytotoxicity was measured in a standard 4-hour ^(51)Cr release assay. We measured the NK cell cytotoxicity after moxibustion stimulation for 1, 3, 5 and 7 days, and also measured the NK cell cytotoxicity after 3 and 7 days burn stimulation with similar temperature. Interleukin (IL)-2, -4 and interferon (INF)-γ in serum were measured by rat IL-2, -4 and INF-γ ELISA test kit. To evaluate the effects of sympathectomy on alteration of NK cell cytotoxicity, 6-hydroxydopamine (6-OHDA: 50 mg/kg) was used. We showed that NK cell activity of moxibustion stimulation group incrcased at the 3rd day, and declined at the 7th day in comparison with that of the control group. In thc moxibustion stimulation group, NK cell activity was significantly higher than the sham group at the 3rd day. On the contrary, in the burn stimulation group, NK cell activity was significantly higher than that of the sham groups at 3rd and 7th days. INF-γ level after 3 days in the moxibustion stimulation group was significantly higher than that of the sham group. IL-2 Ievel among groups were not different. IL-4 was not detected in serum with this method. Sympathectomy abolished the NK cell activity alteration induced by moxibustion. The results suggest that moxibustion modulates NK cell activity, along with INF-γ, and SNS is mediating these effects.

Objectives: We recently have reported that constituents of OMC-2010 have an immuno-modulatory effects via inhibiting tumor necrosis factor (TNF)-alpha and interleukin (IL)-5. In this study, based on previous data, we investigated the effects of combinations with each OMC constituents on splenocyte cytotoxicity, cytokine productions, and ovalbumin (OVA) induced experimental allergic asthma. Methods: Mouse splenocytes were pre-treated with ethanol extract of constituents of Rehmannia glutinosa (RG), Pinellia ternata (PT), Schisandra chinensis (SC). We made 4 combinations using RG, PT, and SC (A;1:1:1, B;2:1:1, C;1:2:1, D;1:1:2). The cells were pretreated with A, B, C, or D for 1 h, then stimulated with lipopolysaccharide (LPS, 1 ㎍/ml) for 48 h. Then the cells were harvested for real-time reverse transcription polymerase chain reaction to detect cytokine productions. Then using effective combination from RG, PR and SC, we administrated the combination orally, then challenged with OVA to induce asthma. Then we analyzed the airway hyper-reactivity (AHR), lung histology and lung TNF-α and IL-5 mRNA. Results: A. B. C. and D did not showed significant cytotoxicity on splenocytes. Pre-treatment of A inhibited the expression of TNF-α and IL-5 significantly, but not B, C, and D. In experimental asthma, administration of A significantly inhibited the increase of AHR, lung damage, TNF-α and IL-5 expression. Conclusions: Theses results could suggest that inhibitory effects of the ideal combination with RG, PT and SC (1:1:1) could be applied to treatment of asthma and study of asthma mechanisms.

S-562 : MicroRNA-155 as a proinflammatory regulator in acute gouty arthritis

( Jung Ho Choi ),( Hye Mi Jin ),( Moon Ju Kim ),( Young Nan Cho ),( Kwang Il Nam ),( Seung Jung Kee ),( Jang Bae Moon ),( Dong Jin Park ),( Yong Wook Park ),( Shin Seok Lee ),( Tae Jong Ki ) 대한내과학회 2013 대한내과학회 추계학술대회 Vol.2013 No.1

Introduction: MicroRNA-155 (miR-155) is crucial for the proinflammatory activation of human myeloid cells and antigen-driven inflammatory arthritis. Since, the functional role of miR-155 in gouty arthritis has not been defined. The aim of this study was to examine the role of miR-155 in pathogenesis of gouty arthritis. Materials and methods: Samples from fourteen patients with gouty arthritis and ten healthy controls were obtained. Monosodium urate (MSU) crystals were prepared by recrystallization from uric acid. Total RNA was isolated using the miRNeasy kit (Qiagen). The miScript Reverse Transcription Kit (Qiagen) was used for cDNA preparation. MiScript primer assay (Qiagen) were used for semiquantitative determination of the expression of human miR-155. Human TNF-α and IL-1β in supernatants were measured by Luminex (Millipore, USA) according to the instructions of the manufacturer. Gout peritonitis mice (Male C57BL/6J) model used to analyze expressions of miR-155, Src homology 2-containing inositol phosphatase-1 (SHIP-1), and inflammatory cytokines. Results: The samples from gout patients proved to be highly enriched in miR-155, with levels of expression being 4-fold higher than those found in peripheral blood mononuclear cells (PBMC) from healthy controls and gout (p<0.05). miR-155 was found to be strongly induced by stimulation of MSU crystals after 24 hours and their expressions gradually decreased. Stimulating with MSU crystals for the indicated times, and the level of SHIP-1 was found to be gradually decreased in according to over-expression of miR-155. miR-155 promoted MSU-induced proinflammatory cytokine production. Commensurate with our observations in human synovial monocytes, miR-155 expression was elevated in gout mice model. SHIP-1 protein levels were markedly reduced in cells by MSU stimulated, compared to the control. MSU crystal induced peritonitis mice significantly increased the production of inflammatory cytokines, such as TNF-α and IL-1β. Conclusion: Overexpression of miR-155 in synovial fluid mononuclear cells (SFMC) led to down-regulation of SHIP-1 and an increase in the production of proinflammatory cytokines.
