        폐포 대식세포 및 단핵구가 Interleukin-2 Enhanced Natural Killer 및 LAK Activity에 미치는 영향

        조철호 ( Jo Cheol Ho ),김병일 ( Kim Byeong Il ),김세규 ( Kim Se Gyu ),천선희 ( Cheon Seon Hui ),김형중 ( Kim Hyeong Jung ),장준 ( Jang Jun ),안철민 ( An Cheol Min ),김성규 ( Kim Seong Gyu ),이원영 ( Lee Won Yeong ),윤정구 ( Yun J 대한내과학회 1992 대한내과학회지 Vol.42 No.5

        저자들은 폐포 대식세포 및 말초혈액내의 단핵구가 NK 활성도 및 LAK 활성도에 미치는 영향을 보기위하여, 임파구에 여러 가지 농도(0, 100 : 1, 10 : 1, 1 : 1)의 폐포 대식세포와 단핵구를 넣어 IL-2 enhanced NK 활성도 및 LAK 활성도를 비교하여 다음과 같은 결과를 얻었다. 1) 여러 가지 농도의 단해구는 IL-2 enchanced NK 활성도 및 LAK 활성도에 영향을 미치지 않았다. 2) 동량의 페포대식세포(임파구 : 폐포 대식세포= 1 : 1)는 IL-2 enhanced NK 활성도를 의의있게 억제하였으나(p<0.05), 소량의 폐포대식세포(임파구 : 폐포 대식세포-10 : 1과 100 : 1)는 IL-2 enhanced NK 활성도를 억제하지 못하였다. 3) 임팍와 폐포 대식세포의 비율이 1 : 1과 10 : 1에서는 LAK 활성도를 의의있게 억제하였으나, 소량의 폐포대식세포(임파구 : 폐포 대식세포=100 : 1)는 LAK 활성도를 억제하지 못하였다(p<0.05). 이상의 결과로 IL-2 enhanced NK 활성도 및 LAK 활성도는 폐포 대식세포의 양에 비례하여 억제되었으나, 말초혈액내의 단핵구에 의해서는 영향받지 않는 것을 알 수 있었다. Alveolar macrophages (AM) are thought to function as primary effector cells against tumors growing in the lung. Systemic administration of lymphokine activated killer (LAK) cells and IL-2 resulted in partial antitumor response in patients with advanced cancer. LAK activity is influenced by various factors. We studied the effects of AM and blood monocytes from healthy donors on IL-2 enhanced NK activity against K-562 cells and LAK activity against Raji cells utilizing a 4h ^(51)Cr release assay. The following results were obtained: 1) The addition of different doses of human blood monocytes showed no suppression or enhancement of IL-2 enhanced NK and LAK activity. 2) The addition of high dose of AM (Lymphocyte: AM=1:1) significantly suppressed IL-2 enhanced NK activity. Smaller doses of AM (Lymphocyte: AM= 10:1and 100:1) did not suppress IL-2 enhanced NK activity. 3) The addition of high dose of AM (Lymphocyte: AM = 1:1 and 10:1) significantly suppressed LAK activity. The smallest dose of AM (Lymphocyte: AM= 100:1) did not suppress LAK activity. In conclusion, IL-2 enhanced NK and LAK activity were dose-dependently suppressed by human alveolar macrophages. However IL-2 enhanced NK and LAK activity were not suppressed by blood monocytes.

        Effects of BCG infection on Schultz - Dale reaction , Allergen - specific IgE levels , and Th2 immune response in sensitized rats

        (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.

        영화광고로 본 1930년대 영화연구

        어일선(Il-Seon Eo) 한국콘텐츠학회 2011 한국콘텐츠학회논문지 Vol.11 No.11

        이 연구는 1930년대 상영영화에 대한 『매일신보』와 『동아일보』에 실린 영화광고를 비교, 분석하였다. 본 논문에서는 형식적인 면에서의 분석보다는 게재내용상의 비교, 분석에 중점을 두고 연구가 진행되었다. 두 신문의 광고는 게재면수나 단수에서는 그 형태상 다소 차이를 보였지만 내용적인 면에서는 『매일신보』와『동아일보』가 대부분 일치하였다. 이러한 결과로 볼 때, 총독부 기관지의 성격을 띤 『매일신보』, 민간신문의 대표격인『동아일보』를 비교 조사한 결과는 광고의 반복을 고려한다면 1930년대 상영작품에 대한 대부분의 광고 자료를 확보한 것으로 1930년대 상영영화 광고 특징에 대한 정확한 분석이 이루어졌다고 할 수 있을 것이다. 이 연구 성과를 바탕으로 보다 확장된 1930년대 한국영화의 특징에 대한 연구가 이루어지기를 기대해 본다. This study analyzed and compared Dong-a Il-bo, a new material, based on the result of analysis of movie commercials on Mae-il Shin-bo from the previous study. Although we could not analyze precisely them in regard to their form, there are differences between them in terms of where they show movie commercials and how large their movie commercials are. However, in terms of the content, the characteristics of movies in the 1930s correspond with the result of the study that analyzed Mae-Il Shin-Bo. As Mae-Il Shin-Bo was actually a organ of the Japanese Government-General of Korea, and Dong-A Il-Bo was a representative of private newspapers, our comparative study actually covered almost all materials on the movies of the 1930s, considering repeating movie commercials. Based on the results of this study, we can learn more precisely the characteristics of the movies in the 1930s.

        (2S)-2′-Methoxykurarinone from Sophora flavescens Suppresses Cutaneous T Cell-Attracting Chemokine/CCL27 Expression Induced by Interleukin-β/Tumor Necrosis Factor-α via Heme Oxygenase-1 in Human Keratinocytes

        Seung-Il Jeong,Young-Eun Lee,Seon Il Jang 한국식품영양과학회 2010 Journal of medicinal food Vol.13 No.5

        One of the CC chemokines, cutaneous T cell-attracting chemokine (CTACK/CCL27), is a skin-specific CC chemokine that is produced constitutively by keratinocytes and is highly up-regulated in inflammatory skin conditions such as atopic dermatitis and contact dermatitis. (2S)-2′-Methoxykurarinone (MOK) from Sophora flavescens has been demonstrated to have antioxidant effects. Heme oxygenase (HO)-1 has recently emerged as an important cytoprotective enzyme against oxidative stress and inflammatory responses in many cell types. This study aimed to define whether and how MOK regulates skin specific CTACK/CCL27 chemokine production in human HaCaT keratinocytes. The level of CTACK/CCL27 and HO-1 expression was measured by reverse transcription-polymerase chain reaction, and signaling was evaluated by western blot analysis. CTACK/CCL27 production was determined by enzyme-linked immunosorbent assay. Pretreatment with MOK suppressed tumor necrosis factor-α (TNF-α)- and interleukin (IL)-1β-induced CTACK/CCL27 production in human HaCaT keratinocytes. MOK inhibited TNF-α- and IL-1β-induced nuclear factor κB (NF-κB) activation. Interestingly, pretreatment with MOK significantly suppressed TNF-α- and IL-1β-induced CTACK/CCL27 production through the induction of HO-1. This suppression was completely abolished by HO-1 small interfering RNA. Furthermore, carbon monoxide, but not other end products of HO-1 activity, also suppressed TNF-α- and IL-1β-induced CTACK/CCL27 production. These results demonstrate that MOK attenuates TNF-α- and IL-1β-induced production of CTACK/CCL27 in human HaCaT keratinocytes by inhibiting NF-κB activation and induction of HO-1.

        위상피세포에서 Helicobacter pylori 형태 변화가 Interleukin-8 분비에 미치는 영향

        이학성,김혜원,홍원선,민영일,정훈용,김해련,양석균,이미화 대한소화기학회 1999 대한소화기학회지 Vol.33 No.6

        Background/Aims: Interleukin-8 (IL-8) has been reported to play a critical role in Helicobacter pylori (H. pylori)-associated gastric mucosal damage. H. pylori exist in both bacillary and coccoid forms in the stomach. In contrast to bacillary forms, it is not clear whether coccoid forms stimulate gastric epithelial cells to produce IL-8. This study was conducted to investigate the effects of coccoid forms on IL-8 production. Methods: H. pylori strains of ATCC 43504, ATCC 43526 and three clinical isolates were used in the present study. Coccoid forms were induced by culturing bacillary forms of H. pylori for more than 84 hr. After co-culture of two human gastric adenocarcinoma cel lines (KATO III and AGS) with five strains of H. pylori, the levels of IL-8 were determined in th supernatants by enzyme linked immunosorbent assay. Results: The levels of IL-8 in KATO III and AGS cells were markedly elevated up to 6-9 hr after co-culture with the bacillary forms. The IL-8 levels produced in both cell lines by the coccoid forms were significantly lower than those by the bacillary forms in all strains. Conclusions: These results suggest that coccoid forms are much less implicated in IL-8- mediated gastric mucosal damage than bacillary forms.

        장선일 ( Jang Seon Il ),윤용갑 ( Yun Yong Gab ) 대한본초학회 2003 大韓本草學會誌 Vol.18 No.3

        N/A Objectives : The present study has been undertaken to investigate the effect of Kagam-Bojungikgitang (KBT) decoction on development of collagen-induced arthrtis (CIA) in DBAl J mice. Methods : CIA was induced in UBAJ1 mice by immunization with bovine type II collagen (CIU and treatment with lipopolysacchride (LPS). KBT is the water extracts prepared from Ginseng Radix, Astragali Radix, Angelicae gigantis Radix, Astractylodis Rhizoma alba, Aurantii nobilis Pericarpium, Glycyrrhizae Radix, Artemisiae iwayomogii Herba, Scutellariae Radx. This is a modifitd prescription of Bojungikgitang, which has been used for the treatment of indigestion, and immunological disease in oriental countries. KBT was orally administered at difference doses. The incidence of arthritis, arthritis index, levels of tumor necrosis factor -alpha (TNF-a). interferon-gama (IFN-V), interleukin lbeta (IL-lP), IL - 3 . IL--10, II- 13. and prostaglandin E? (PGE.1 and cyclooxygenase~-2 (COX21 activity were investigated. Results : KBT dose- dependently suppressed the release of T h l cytokines (TNF-a, IFN-.v, and IL-1 8 ) and inflammatory mediators (PGE? and COX--2 caused by immunization of CII and stimulation of 1,PS. KUT without cytotoxic effext. Kagam-bojunyikgitang`s Inhibitory effects were better than Ehjungikgitang in PGEz production and COX-2 expression. However, KBT increased markedly the production of Th:! cytokines (IL-4, IL 10, and IL -13). Therefor , KBT suppressed markedly the incidence of arthritis and arthritis index caused by immunization of CII and stimulation of LPS. Conclusion : These results suggest that KBT suppress inflammatory mediators and regulates Th l and Th2 cytokmes. And these properties may contribute to the strong anti-arthritis of KBT.

      • 2,3-Dehydrosilybin Suppresses IL-31-Associated Pruritus Factors in Astrocytes and Microglia

        Ji Hyeon Park,Jae Young Shin,Feng Wang,Suping Hao,Da Jeong Shin,Seon Il Jang,Byoung Ok Cho 한국식품영양과학회 2021 한국식품영양과학회 학술대회발표집 Vol.2021 No.10

        Chronic pruritus is the main symptom that increases the suffering of patients in hypersensitivity disorder disease. IL-31 is a pruritic cytokine with a primary objective to control itch. A 2,3-dehydrosilybin (DHS) is a type of flavonoid extracted from the seeds of milk thistle. DHS has been reported to have hepatoprotective, angiogenic, and antioxidant effects. This study investigated the effect of DHS pretreatment on IL-31-associated pruritus in astrocytes and microglia. Pretreatment with DHS inhibited the production of IL-31 by lipopolysaccharide (LPS) and interferon gamma (IFN-γ) stimulation in microglia. Pretreatment with DHS inhibited the phosphorylation of MAPK, STAT1 and NF-κB by LPS plus IFN-γ stimulation in microglia. In addition, DHS suppressed the expression of IL-31 receptor A in IL-31-treated astrocytes. DHS also inhibited lipocalin2 production in IL-31 stimulated astrocytes. Taken together, DHS has potential as a therapeutic agent for symptom relief by down-regulating the IL-31-mediated pruritus mechanism in microglia and astrocytes.

        Objectives : The aim of this study was to know the immunity responses of Gwanjulbang-1(Quanjiefang-1)(hereinafter referred to GJB-1) to on Rheumatoid Arthritis in Collagen-induced Arthritis(CIA) Mice Methods : For this purpose, experiments were performed to measure the cytotoxicity against mLFC, hFLSs and the production of proinflammatory cytokines IL-1β, IL-6, TNF-α, IFN-γ in hFLSs and the production of pro-inflammatory cytokines IL-4, IL-10 and the value of CD3+(T), CD19+(B), CD3+/CD69+, CD4, γδ T cells, CD4+/CD25+ Results : 1. The cytotoxicity against mLFC, hFLSs were not measured. 2. The production of pro-inflammatory cytokines IFN-γ were reduced in hFLSs. 3. The production of pro-inflammatory cytokines IL-4, IL-10 were increased. 4. Statistically significant value of CD3+(T), CD19+(B), CD3+/CD69+, CD4, γδ T cells, CD4+/CD25+ compared with control group, wild type, MTX. Conclusions : Comparison of the results for this study showed that GJB-1 had immunomodulatory effects of suppressing or enhancing. So we expect that GJB-1 should be used as a effective drugs for not only rheumatoid arthritis but also another auto-immune disease. Therefore we have to survey continuously in looking for the effective substance and mechanism in the future.

        Inflammatory Endotypes of Chronic Rhinosinusitis in the Korean Population: Distinct Expression of Type 3 Inflammation

        Min Jin-Young,Kim Jin Youp,성충만,Kim Seon Tae,조현진,문수진,Cho Sung-Woo,Hong Sang Duk,Ryu Gwanghui,Cho Kyoung Rai,Kim Young Hyo,Park Soo-Kyoung,Kim Dong-Kyu,Lee Dong Hoon,Heo Sung Jae,Lee Ki-Il,Kim Su Jin,Le 대한천식알레르기학회 2023 Allergy, Asthma & Immunology Research Vol.15 No.4

        Purpose: Cluster analyses on inflammatory markers of chronic rhinosinusitis (CRS) in Asians from multicenter data are lacking. This multicenter study aimed to identify the endotypes of CRS in Koreans and to evaluate the relationship between the endotypes and clinical parameters. Methods: Nasal tissues were obtained from patients with CRS and controls who underwent surgery. The endotypes of CRS were investigated by measuring interleukin (IL)-5, interferon (IFN)-γ, IL-17A, IL-22, IL-1β, IL-6, IL-8, matrix metalloproteinase-9, eotaxin-3, eosinophil cationic protein, myeloperoxidase (MPO), human neutrophil elastase (HNE), periostin, transforming growth factor-β1, total immunoglobulin E (IgE), and staphylococcal enterotoxin (SE)-specific IgE. We performed hierarchical cluster analysis and evaluated the phenotype, comorbidities, and Lund-Mackay computed tomography (LM CT) score in each cluster. Results: Five clusters and 3 endotypes were extracted from 244 CRS patients: cluster 1 had no upregulated mediators compared to the other clusters (mild mixed inflammatory CRS); clusters 2, 3, and 4 had higher concentrations of neutrophil-associated mediators including HNE, IL-8, IL-17A, and MPO (T3 CRS); and cluster 5 had higher levels of eosinophil-associated mediators (T2 CRS). SE-specific IgE was undetectable in T3 CRS and had low detectable levels (6.2%) even in T2 CRS. The CRS with nasal polyps (CRSwNP) phenotype and LM CT scores showed no significant differences between T2 and T3 CRS, while the incidence of comorbid asthma was higher in T2 CRS than T3 CRS. In T3 clusters, higher levels of neutrophilic markers were associated with disease severity and CRSwNP phenotype. Conclusions: In Koreans, there is a distinct T3 CRS endotype showing a high proportion of CRSwNP and severe disease extent, along with T2 CRS.

        감껍질 열수 및 초임계 유체 추출물의 항아토피 효과

        조병옥(Byoung Ok Cho),윤홍화(Hong Hua Yin),방숭주(Chong Zhou Fang),신재영(Jae Young Shin),하혜옥(Hye Ok Ha),김상준(Sang Jun Kim),정승일(Seung Il Jeong),장선일(Seon Il Jang) 한국식품과학회 2015 한국식품과학회지 Vol.47 No.3

        본 연구에서는 고종시 감껍질을 열수 추출 및 초임계 유체 추출하여 아토피 피부염 증상 억제 효과를 밝히고, 항염 효능을 나타내는 기능성 소재로서의 이용 가능성을 알아보고자 하였다. 그 결과 육안 평가를 통해 피부의 홍반(erythema), 가려움과 피부의 건조상태(pruritus and dry skin), 부종과 혈종(edema and excoriation), 짓무름(erosion), 그리고 태선화(lichenification)와 같은 아토피 피부염 같은 증상이 AD 모델에서 증가하였지만, SPPE와 PPWE를 투여하였을 경우 완화되는 것을 확인할 수 있었으며, SPPE가 PPWE보다 더 뛰어난 효과를 나타내었다. 피부 두께와 염증 세포의 침윤은 AD 모델에서 크게 증가하였지만, SPPE와 PPWE를 투여하였을 경우 감소하는 것을 확인할 수 있었으며, SPPE가 PPWE보다 더 뛰어난 효과를 나타내었다. 혈청 중의 IgE와 IL-4의 수치를 측정한 결과, AD 모델에서 크게 증가하였으나 SPPE와 PPWE를 투여하였을 경우 감소하는 것을 확인할 수 있었으며, SPPE가 PPWE보다 더 뛰어나게 억제하는 효과를 나타내었다. 또한 RAW264.7 세포에 SPPE를 처리하였을 경우 염증매개 인자인 NO, PGE2, IL-6, IL-1β의 생성량이 유의적의로 감소하였고, PPWE의 경우 NO, PGE2, IL-1β의 생성을 억제한 반면 IL-6 생성 억제에는 영향을 나타내지 않았다. 이러한 염증 매개인자 억제 효능은 SPPE가 PPWE보다 더 뛰어나게 억제하는 것을 확인하였다. 따라서 감껍질 추출물은 아토피 피부염 증상 개선과 염증관련 질환 치료를 위한 기능성 천연물 소재로 유용하게 활용될 수 있을 것으로 판단된다. This study aimed to investigate the anti-atopic effect of hot water (PPWE) and supercritical-carbon dioxide fluid extract of persimmon peels (SPPE) on atopic dermatitis (AD)-like skin lesions in hairless mice. Histological analyses demonstrated that SPPE treatment more strongly inhibited the dermal infiltration of inflammatory cells in AD-like skin lesions than that by PPWE. Compared to PPWE, SPPE significantly decreased the dermatitis clinical score and the epidermal thickness and potently suppressed serum IgE and interleukin (IL)-4 production in hairless mice with AD. Furthermore, compared to PPWE, SPPE potently inhibited the production of nitric oxide, prostaglandin E₂, and proinflammatory cytokines such as IL-6 and IL-1β in lipopolysaccharide-stimulated RAW264.7 macrophages. These results suggested that SPPE exhibited anti-atopic dermatitis activity via the regulation of inflammatory responses.
