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.

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.

조병옥(Byoung Ok Cho),윤홍화(Hong Hua Yin),신재영(Jae Young Shin),방숭주(Chong Zhou Fang),체 데니스 창(Chong Zhou Fang),장선일(Seon Il Jang) 한국식품영양과학회 2016 한국식품영양과학회지 Vol.45 No.4

본 연구는 고욤잎, 감잎 및 뽕잎을 단독으로 사용하기보다 혼합하여 사용할 경우 고욤잎, 감잎 및 뽕잎 복합추출물이 아토피 피부염(AD) 증상을 억제하는지 효과를 밝히고, 항염효능을 나타내는 기능성 소재로서의 이용 가능성을 알아보고자 하였다. 그 결과 육안 평가를 통해 피부의 건조 상태, 스케일링, 미란, 찰과상 및 홍반 같은 아토피 피부염 증상이 AD 모델에서 증가하였지만, 고욤잎, 감잎 및 뽕잎 각각의 추출물과 복합추출물을 투여하였을 경우 완화되는 것을 확인할 수 있었으며, 복합추출물이 고욤잎, 감잎 및 뽕잎 각각의 추출물보다 더 뛰어난 효과를 나타내었다. 피부 두께와 염증세포 및 비만세포의 침윤은 AD 모델에서 크게 증가하였지만, 고욤잎, 감잎 및 뽕잎 단독추출물과 복합추출물을 투여하였을 경우 감소하는 것을 확인할 수 있었으며, 복합추출물이 단독추출물보다 더 뛰어난 효과를 나타내었다. 혈청중의 IgE와 IL-4의 수치를 측정한 결과 AD 모델에서 많이 증가하였으나, 고욤잎, 감잎 및 뽕잎 단독추출물과 복합추출물을 투여하였을 경우 감소하는 것을 확인할 수 있었으며, 복합추출물이 단독추출물보다 더 뛰어나게 억제하는 효과를 나타내었다. HMC-1 세포에 복합추출물을 처리하였을 경우 염증성 사이토카인인 TNF-α와 IL-6의 생성량이 유의적으로 감소하였으며, 또한 RAW 264.7 세포에 복합추출물을 처리하였을 경우 염증 매개 인자인 TNF-α, IL-6, PGE2 및 NO 생성량이 감소하였고, 이러한 염증 매개 인자 억제 효능은 복합추출물이 단독추출물보다 더 뛰어나게 억제하는 것을 확인하였다. 이러한 결과로 미루어볼 때 고욤잎, 감잎 및 뽕잎을 혼합한 복합추출물을 사용할 때 효능이 더 우수한 것을 확인하였고, 아토피 피부염 증상 개선 및 염증관련 질환 치료를 위한 기능성 천연물 소재 및 제품 개발에 응용이 가능할 것으로 생각한다. The present study investigated the anti-atopic effects of mixed extracts from date plum, persimmon, and mulberry leaves (DPME) on atopic dermatitis (AD)-like skin lesions in hairless mice. The in vivo results demonstrated that DPME treatment significantly reduced the dermatitis clinical score and epidermal thickness in AD-like skin lesions. Histological analyses showed that DPME treatment strongly inhibited dermal infiltration of inflammatory cells and activity of mast cells in AD-like skin lesions. DPME treatment inhibited production of serum IgE and interluekin (IL)-4 in hairless mice with AD. Moreover, DPME treatment significantly suppressed production of tumor necrosis factor (TNF)-α and IL-6 cytokines in phorbol 12-myristate 13-acetate plus calcium ionophore A23187-stimulated HMC-1 human mast cells. In addition, DPME treatment reduced production of pro-inflammatory mediators (nitric oxide, prostaglandin E2, TNF-α, and IL-6) in lipopolysaccharide-stimulated RAW 264.7 macrophages. Therefore, the results of this study indicate that the anti-atopic and anti-inflammatory effects of DPME may be involved in the regulation of inflammatory responses, suggesting that DPME may be used as an anti-atopic dermatitis material and natural anti-inflammatory ingredient.

조병옥(Byoung Ok Cho),윤홍화(Hong Hua Yin),방숭주(Chong Zhou Fang),하혜옥(Hye Ok Ha),김상준(Sang Jun Kim),정승일(Seung Il Jeong),장선일(Seon Il Jang) 한국식품과학회 2015 한국식품과학회지 Vol.47 No.1

본 연구에서는 들깨 유래 기능성 물질인 rosmarinic acid (RA)와 luteolin이 RAW264.7 세포에서 항염증작용에 대한 상승 효과가 있는지 알아보고자 하였다. 그 결과 RAW264.7 세포에 RA (50 μM)와 luteolin (1 μM)을 동시에 처리하였을 경우 염증 매개 인자인 NO, iNOS, PGE2, COX-2의 생성을 RA (100 μM)와 luteolin (2 μM)을 각각 처리하였을 때 보다 더 뛰어나게 억제하였다. 또한 RA (50 μM)와 luteolin (1 μM)을 동시에 처리하였을 경우 TNF-α, IL-6, IL-1β 같은 염증성 사이토카인의 생성량을 RA (100 μM)와 luteolin (2 μM)을 각각 처리하였을 때 보다 더 뛰어나게 억제하는 것을 확인하였다. 그리고 RA (50 μM)와 luteolin (1 μM)을 동시에 처리하였을 경우 RA (100 μM)와 luteolin (2 μM)을 각각 처리하였을 때 보다 NF-κB의 subunit인 p65의 translocation과 IκB-α의 degradation을 더 뛰어나게 억제하는 것을 볼 수 있어 두 화합물 간의 상승작용이 뚜렷함을 확인 할 수 있었고, RA와 luteolin 두 화합물을 동시에 처리할 경우 염증관련 질환 치료에 유용하게 활용될 수 있을 것으로 판단된다. The aim of this study was to investigate the synergistic anti-inflammatory effect of rosmarinic acid (RA) and luteolin from perilla (Perilla frutescens L.) leaves in lipopolysaccharide (LPS)-stimulated RAW264.7 macrophages. A combination of RA and luteolin more strongly inhibited the production of nitric oxide (NO), inducible NOS (iNOS), prostaglandin E2 (PGE2), and COX-2 than higher concentrations of RA or luteolin alone in LPS-stimulated RAW264.7 macrophages. The combined RA and luteolin synergistically inhibited the production of pro-inflammatory cytokines, such as tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and interleukin-1β (IL-1β), in LPS-stimulated RAW264.7 macrophages. Furthermore, combined RA and luteolin more strongly suppressed NF-κB activation than RA or luteolin alone, by inhibiting the degradation of inhibitor of NF-κB (IκB)-α and nuclear translocation of the p65 subunit of NF-κB in LPS-stimulated RAW264.7 macrophages. Collectively, these results suggest that RA and luteolin in combination exhibit synergistic effects in suppression of LPS-induced inflammation in RAW264.7 macrophages.

Cho, Byoung Ok,Yin, Hong Hua,Park, Sang Hyun,Byun, Eui Baek,Ha, Hun Yong,Jang, Seon Il Informa UK (TaylorFrancis) 2016 Bioscience, biotechnology, and biochemistry Vol.80 No.8

<P>Diospyros lotus is traditionally used for the treatment of diabetes, diarrhea, tumor, and hypertension. The purpose of this study was to investigate the anti-inflammatory effect and underlying molecular mechanisms of myricetin in lipopolysaccharide (LPS)-stimulated RAW264.7 macrophages. Myricetin dose-dependently suppressed the production of pro-inflammatory mediators (NO, iNOS, PGE(2), and COX-2) in LPS-stimulated RAW264.7 macrophages. Myricetin administration decreased the production of NO, iNOS, TNF-, IL-6, and IL-12 in mice. Myricetin decreased NF-B activation by suppressing the degradation of IB, nuclear translocation of p65 subunit of NF-B, and NF-B DNA binding activity in LPS-stimulated RAW264.7 macrophages. Moreover, myricetin attenuated the phosphorylation of STAT1 and the production of IFN- in LPS-stimulated RAW264.7 macrophages. Furthermore, myricetin induced the expression of HO-1 through Nrf2 translocation. In conclusion, these results suggest that myricetin inhibits the production of pro-inflammatory mediators through the suppression of NF-B and STAT1 activation and induction of Nrf2-mediated HO-1 expression in LPS-stimulated RAW264.7 macrophages.</P>

Cho, Byoung Ok,Che, Denis Nchang,Yin, Hong Hua,Shin, Jae Young,Jang, Seon Il Elsevier 2017 BIOMEDICINE AND PHARMACOTHERAPY Vol.89 No.-

<P><B>Abstract</B></P> <P>Atopic dermatitis, a chronic relapsing and pruritic inflammation of the skin also thought to be involved in, or caused by immune system destruction is an upsetting health problem due to its continuously increasing incidence especially in developed countries. Mast cell infiltration in atopic dermatitis skin lesions and its IgE-mediated activation releases various cytokines and chemokines that have been implicated in the pathogenesis of atopic dermatitis. This study was aimed at investigating synergistic anti-inflammatory, anti-pruritic and anti-atopic dermatitis effects of <I>Diospyros lotus</I> leaf extract (DLE) and Muscat bailey A grapefruit stem extract (GFSE) in atopic dermatitis-like induced skin lesions in mice. Combinations of DLE and GFSE inhibited TNF-α and IL-6 production more than DLE or GFSE in PMA plus calcium ionophore A23187-activated HMC-1 cells. DLE and GFSE synergistically inhibited compound 48/80-induced dermal infiltration of mast cells and reduced scratching behavior than DLE or GFSE. Furthermore, DLE and GFSE synergistically showed a stronger ameliorative effect in skin lesions by reducing clinical scores; dermal infiltration of mast cells; ear and dorsal skin thickness; serum IgE and IL-4 production in atopic dermatitis-like mice. Collectively, these results suggest that DLE and GFSE synergistically exhibit anti-atopic dermatitis effects in atopic dermatitis-like skin lesions in mice.</P>

윤홍화(Hong Hua Yin),조병옥(Byoung Ok Cho),이혜승(Hye Seung Lee),추정임(Jung Im Chu),장선일(Seon Il Jang) 한국식품과학회 2016 한국식품과학회지 Vol.48 No.6

본 연구는 캠벨어얼리 포도가지와 새송이버섯 혼합 추출물이 활성화된 면역세포에서 항염증 및 화학항원과 생물학적 항원을 동시에 처리한 아토피 피부염 유사 모델 마우스에서 아토피 개선에 대한 상승효과를 알아보았다. 그 결과 지방질다당류로 자극된 RAW 264.7 세포에 포도가지와 새송이버섯 각각의 추출물 처리했을 때 보다 이들 추출물을 혼합하여 처리할 때 산화질소와 PGE2 생성을 효과적으로 억제하였다. 또한 지방질다당류로 자극된 RAW 264.7 세포와 PMA와 A23187로 활성화된 HMC-1 세포에서도 각각의 추출물 보다 혼합추출물을 처리했을 때 TNF-α와 IL-6 생성에 대한 억제 효과가 매우 우수하였다. 더욱이 DNCB와 집먼지진드기 항원으로 유도된 아토피 피부염 유사 모델에서 포도가지와 새송이버섯 혼합 추출물 투여는 각각의 추출물 투여에 비해서 외부적 피부병변과 피부두께 및 피부조직학적 등 임상적으로 아토피 피부염에 대한 개선 효과가 매우 뛰어남을 확인할 수 있었다. 이러한 포도가지와 새송이버섯 혼합 추출물의 아토피 피부염 개선 효과는 혈청 내 IgE와 IL-4의 생성을 억제함으로써 각각의 추출물에 비해서 상승되는 효과가 있음을 나타내 주었다. 이러한 결과는 포도가지와 새송이버섯 각각의 추출물 투여보다는 이들의 추출물을 혼합하여 투여하는 것이 아토피 피부염을 개선시키는데 효과적임을 알 수 있었다. The aim of this study was to investigate the synergistic anti-inflammatory and anti-dermatitis effects of grape branch extract (GBE) and Pleurotus eryngii (PEE) combinations on the active immune cells and atopic dermatitis-like skin lesions in mice. The results showed that the combination of GBE (12.5 μg/mL) and PEE (500 μg/mL) led to much stronger inhibitory effects on the production of inflammatory mediators, such as NO and PGE2 than that exhibited by GBE(25 μg/mL) and PEE (1000 μg/mL) alone, even at higher concentrations, in LPS-stimulated RAW 264.7 macrophages. The combination of GBE and PEE synergistically inhibited the production of TNF- and IL-6 in LPS-stimulated RAW 264.7 macrophages and PMA plus A23187-activated HMC-1 cells. Furthermore, combined GBE and PEE had a stronger ameliorative effect than GBE and PEE alone by inhibiting the clinical sores, IgE, and IL-4 on atopic dermatitis-like skin lesions in mice. Collectively, these results suggested that the combination of GBE and PEE produced a synergistic antiinflammatory and anti-atopic dermatitis effect on immune cells and atopic dermatitis-like skin lesions in mice.

( Byoung Ok Cho ),( Hyung Won Ryu ),( Yang Kang So ),( Chang Wook Lee ),( Chang Hyun Jin ),( Hong Sun Yook ),( Yong Wook Jeong ),( Jong Chun Park ),( Il Yun Jeong ) 한국응용약물학회 2014 Biomolecules & Therapeutics(구 응용약물학회지) Vol.22 No.4

Mangostenone F (MF) is a natural xanthone isolated from Garcinia mangostana. However, little is known about the biological activities of MF. This study was designed to investigate the anti-infl ammatory effect and underlying molecular mechanisms of MF in lipopolysaccharide (LPS)-stimulated RAW264.7 macrophages. MF dose-dependently inhibited the production of NO, iNOS, and pro-infl ammatory cytokines (TNF-α, IL-6, and IL-1β) in LPS-stimulated RAW264.7 macrophages. Moreover, MF decreased the NF-κB luciferase activity and NF-κB DNA binding capacity in LPS-stimulated RAW264.7 macrophages. Furthermore, MF suppressed the NF-κB activation by inhibiting the degradation of IκBα and nuclear translocation of p65 subunit of NF-κB. In addition, MF attenuated the AP-1 luciferase activity and phosphorylation of ERK, JNK, and p38 MAP kinases. Taken together, these results suggest that the anti-infl ammatory effect of MF is associated with the suppression of NO production and iNOS expression through the down-regulation of NF-κB activation and MAPK signaling pathway in LPS-stimulated RAW264.7 macrophages.

조병옥(Byoung Ok Cho),윤홍화(Hong Hua Yin),체 데니스 창(Denis Nchang Che),김상준(Sang Jun Kim),유철(Cheol Ryu),장선일(Seon Il Jang) 한국식품과학회 2016 한국식품과학회지 Vol.48 No.6

본 연구에서는 우리나라에서 가장 많이 재배되고 있는 캠벨어얼리 포도 품종에서 포도가지를 대상으로 산화방지, 항염증 및 항가려움증 효과를 검증하고 활성물질을 나타내는 지표물질을 추적 조사하였다. 그 결과 포도가지 추출물의 총 폴리페놀과 총 플라보노이드 함량은 각각 201.42±4.16과 11.85±0.44 mg GAE/g으로 조사되었다. 또한 캠벨어얼리 포도가지 추출물의 ABTS와 DPPH 라디칼 소거 활성은 각각 45.60±0.09 (IC50)과 299.13±0.22(IC<SUB>50</SUB>)으로 나타나 산화방지 활성이 우수하였다. 게다가 캠벨어얼리 포도가지 추출물은 지방질다당류로 활성화된 RAW 264.7 세포에서 전염증성 매개물인 산화질소와 프로스타글란딘 E₂를 iNOS와 COX-2 분자 발현 억제를 통하여 억제하였고, 전염증성 사이토카인인 인터류킨-1베타와 인터류킨-6를 농도 의존적으로 억제하는 효능이 있었다. 더욱이 phorbol 12-myristate 13-acetate (PMA)와 calcium ionophore A23187로 활성화된 인간 유래 비만세포인 HMC-1 세포에서 종양괴사인자-알파와 인터류킨-6를 농도 의존적으로 억제하는 효능이 있었다. 마지막으로 Compound 48/80으로 유도되는 마우스 가려움증을 캠벨어얼리 포도가지 추출물은 효과적으로 억제하였다. 이러한 캠벨어얼리 추출물에서 활성을 나타내는 물질을 추적한 결과 레스베라트롤의 함량이 높게 검출되었다. 그러므로 본 연구의 결과를 종합해 볼 때 캠벨어얼리 포도가지 추출물은 아토피 질환에서 나타나는 염증과 가려움증을 효과적으로 제어할 수 있는 효과적인 소재임을 제시하였다. This study was designed to investigate the antioxidant activities of the ethanol extracts (GBE) of grape branches (Campbell Early). The total polyphenol and flavonoid content of GBE was 201.42±4.16 and 11.85±0.44 mg GAE/g, respectively. The antioxidant activity of GBE was measured using the ABTS and DPPH assays, and the IC<SUB>50</SUB> values were 45.60±0.09 and 299.13±0.22, respectively. GBE inhibited the production of pro-inflammatory mediators (NO, iNOS, PGE₂, COX-2, IL-1β, and IL-6) in lipopolysaccharide-stimulated RAW 264.7 macrophages in a dose-dependent manner. Moreover, GBE treatment significantly suppressed the production of TNF-α and IL-6 cytokines in phorbol 12-myristate 13-acetate plus calcium ionophore A23187-stimulated HMC-1 human mast cells. Furthermore, the administration of GBE markedly inhibited the scratching behavior induced by the compound 48/80 in ICR mice. These results suggested that GBE has potential as a therapeutic agent against inflammation and itch-related skin diseases.
