본 연구는 하수오에서 분리한 PM-E와 PM-70M를 이용하여 GATA-3의존성 Th2세포 조절과 IgE 억제 효과를 실험하였다. 하수오를 물질분리하여 GATA-3 전사인자 활성을 억제하는 하수오 물질분획층이 흡착크로마토그래피를 통하여 70% 메탄올층에 포함되어 있다고 분석하였다. 그 결과 PM-70 %MFL 분획이 Th2 사이토카인을 조절하는 GATA-3를 억제하여 항알레르기 작용 효과가 있다고 생각된다. 하수오를 흡착크로마토그래피로 분리하여 분획들을 anti-CD40/rmIL-4와 동시 배양하여 B세포에서 IgE 분비를 억제하는지를 알아본 결과, PM-30M층, PM-70A, 그리고 PM-30A층의 IL-6와 TNF-${\alpha}$ mRNA, IgE 분비량은 대조군과 차이가 없었다. 그러나 IL-6와 TNF-${\alpha}$ mRNA 유전자 발현은 각각 $0.69{\pm}0.058$(p<0.001)과 $0.72{\pm}0.58$ (p<0.05)로 대조군에 비하여 30% 이상 유의하게 억제하였다. IgE 분비량은 $94.6{\pm}16.0$으로 대조군에 비교하였을 때 45.6% 이상 유의하게 감소를 나타내었다 (p<0.01). 본 연구를 통해 하수오의 분획중 PM-70 %MFL층에 B세포의 분화 및 활성을 억제하는 성분이 포함된 것으로 사료된다.

This study aims to evaluate the anti-inflammatory effect of Coptidis Rhizoma (CR) extract for atopic dermatitis through maintaining skin barrier and regulating Th2 cell differentiation. We divided NC/Nga mice into 3 groups as follows; atopy-like dermatitis induced group with CR treatment (CT, n=10), no treatment group(Ctrl), atopy-like dermatitis elicited group(AE). Atopy-like dermatitis was induced to NC/Nga mice by sensitizing with dermatophagoides farinae(DfE) on 7, 8, 9, 11, 12, and 13th week. After inducing atopic dermatitis, CR extract was administered 20 mg/kg daily for the experimental duration to the CT group. We measured the integrity of lipid layers in the epidermis and Th2 differentiation through immunohistochemical staining against filaggrin, loricrin, IL-4, and IL-13. We also measured the distribution of subcutaneous collagen fibers by the Masson's trichrome staining. Administration of CR significantly inhibited the reduction of lipid layers in the skin that caused atopy. The expression of IL-4, IL-13, each of which is a cytokine secreted by T helper type 2 (Th2) cells, was markedly suppressed in the CT group as compared with AE group (p<0.05). CR treatment also decreased the expression of iNOS, $p-I{\kappa}B$. Atopic dermatitis induced dermatological damage to skin, such as hyperplasia of epithelium, and capillary proliferation was significantly reduced by CR administration. CR effectively inhibited the thinning of the skin barrier and inflammatory responses in atopic dermatitis-induced mice. In particular, it showed anti-inflammatory effects by reducing the expression of IL-4 and IL-13, Th2 cell cytokines, which play a crucial role in development of atopic dermatitis. Therefore, CR can be a good candidate to ameliorate and treat atopic dermatitis.

Objective : This study summarized the characteristics of clinical trials for atopic dermatitis medicines approved by the Ministry of Food and Drug Safety(MFDS). This study may be a reference for the design of clinical trials of atopic dermatitis herbal medicine treatment which may be carried out later. Method : The characteristics of the clinical trial were analyzed for clinical trials registered with ClinicalTrials.gov, CRIS, and the Korea Health Industry Development Institute among the clinical trial approval statuses posted on the website of the MFDS. Result : 1. Clinical trial drugs were developed in various formulations such as oral medicines, injections, dermatologic agents, and similar proportions. Relatively little clinical trials were found for herbal medicine. 2. In the control evaluation test, most of the treatments for the control group were performed with placebo using Vehicle. 3. In most clinical trials, one intervention group was in the form of a parallel assignment with only one treatment. 4. The age of the subjects was 11 out of 28 studies including minors, and clinical trials targeting minors were also found to be significant. 5. In the case of atopic dermatitis, the cases of subacute chronic or atopic dermatitis more than 6 months or more than 1 year were often used. 6. Most clinical trials were divided into mild to moderate atopic dermatitis or moderate to severe atopic dermatitis. The SCORAD index, EASI, IGA, BSA, and NRS were used as the evaluation criteria. 7. Regulations for the drugs used prior to the trial period for the treatment of atopic dermatitis vary somewhat from one clinical trial to another. 8. IGA was used most often as a primary efficacy tool, and SCORAD index, EASI, and NRS were also used.

Eruca sativa (E. sativa)는 루꼴라라고 불리우고 이탈리아 요리에 많이 사용되는 식물로 Brassicaceae 속에 속하는 다년생 식물이다. E. sativa를 70% 에탄올로 환류추출 및 농축하고 (ES), n-hexane (EHex), ethyl acetate (EEA), chloroform (ECHCl₃), n-butyl alcohol (EBuOH) 및 water (EDW) 용매 극성별로 분획하여 미백 효능을 규명하고 화장품 소재로서의 응용성을 연구하였다. ES, EHex, EEA, ECHCl₃, EBuOH 및 EDW의 mushroom tyrosinase 활성 저해를 평가한 결과 EEA가 가장 유의하게 저해하였으며, B16F10 멜라노마 세포 내에서의 멜라닌 생성을 확인한 결과 ES, EEA 및 EBuOH를 처리하였을 때 멜라닌 생성이 유의하게 저해되었으며, 특히 EEA 분획물에서 가장 효과가 뛰어났다. 피부염과 여드름을 일으키는 황색포도상구균, 여드름 원인균을 포함한 8종의 세균, 진균에 대해 ES, EHex, EEA, ECHCl₃, EBuOH 및 EDW의 항균력과 방부력 시험을 평가한 결과 EEA는 8종의 균 모두 효과적으로 항균력을 나타냈다. ES를 0.05, 0.1%를 함유하여 제조한 토너와 에멀션은 기존 처방에서 방부력을 증가시켜 천연보존제 역할을 할 수 있을 것으로 판단된다. ES를 토너, 에멀션 제형에 0.05, 0.1%로 첨가하여 일광, -20, 4, 25, 55 ℃ 조건에서 4 개월동안 안정성을 평가한 결과 pH 및 점도에 대한 영향은 크게 없었으나 대조군 및 ES를 첨가한 에멀션 55 ℃에서 분리가 일어나는 것을 확인하였다. 또한, 피부침투시험을 통해 EEA는 6 hr에서 0.058%가 침투되어 임상적인 효능을 예측할 수 있었다. 천연소재 E. sativa는 미백 기능성화장품 소재 및 천연 항균 보존제로 활용 가치가 있을 것으로 사료된다.

본 연구는 PFEG(글루코실세라마이드 4.0% 함유)가 저 미네랄 특수사료(HR-AD)를 섭취시킨 헤어리스 마우스에서 발생하는 피부장벽 붕괴에 대한 억제작용이 있는지를 확인하고자 하였다. 4주간의 투여를 통해 정상군(Rabo MR Stock)과 비교하여 대조군(HR-AD)에서는 경피 수분 손실량(TEWL)이 서서히 상승하여 피부장벽기능의 붕괴가 발생함과 동시에 표피 수분량 및 각층 수분량도 서서히 저하되는 것이 확인되었다. 육안적으로는 깊은 주름 형성이 확인되었으며 조직학적 소견에서는 표피의 비후와 각화 항진이 확인되었다. 그러나 PFEG를 섭취시킨 시험군에서는 대조군에서 유발되는 피부장벽기능 붕괴에 대한 억제 효과가 확인되었다. 즉, 글루코실세라마이드 0.01% 배합군 및 0.1% 배합군에서는 섭취 시작 2주일째 이후 야기되는 TEWL 상승을 완전히 억제하였다. 또한, 저하되는 표피 수분량, 각층 수분량에 대해서도 유의하게 억제하여 피부 보습 기능을 유지하고 있었다. 육안적으로도 깊은 주름 형성은 억제되었으며, 조직학적인 검토에서도 표피의 비후나 각화 항진은 확인되지 않았다. 이러한 결과는 HR-1 마우스의 피부 세라마이드 생산 개선에 기인한 결과라고 예상된다. 즉, HR-AD 섭취에 의해 HR-1 마우스는 세라마이드를 포함한 피부 지질의 함량 및 구성에 이상이 생기고, 피부 수분량이 급격히 줄어들어 피부 보습 능력이 저하된다. 그런데 PFEG의 혼합 투여는 손상된 피부의 세라마이드 함량 및 구성을 정상과 가깝게 만들어, 대조군에서 나타나는 증상의 발현을 억제하는 것으로 판단된다. 이상의 결과로부터 PFEG의 섭취는 피부장벽기능의 손상으로 발생하는 다양한 피부 수분 손실을 억제함으로써 피부 보습 개선에 우수한 효능이 있음을 알 수 있었다. 따라서 PFEG가 피부 보습에 도움을 주는 건강기능성 원료로서 이용 가능성이 높음을 확인할 수 있다.

Objectives : This study is to report a case of otitis media with effusion accompanied by atopic dermatitis improved by Korean medicine monotherapy. Methods : A 31-year-old woman patient visited our clinic for aural fullness, hearing loss, and tinnitus of the left ear on August 14th, 2021. She also had abdominal pain, diarrhea, and general weakness because of side effects of antibiotics. Besides, she had nasal congestion, rhinorrhea, and dry skin. Through otoscopy, her tympanum was fully filled with yellow effusion. She only took Korean medicine therapy including acupuncture and herbal medicine weekly. The treatment continued for about 4 months(total 14 visits) until December 4th, 2021. Otoscopy, numerical rating scale(NRS), scoring atopic dermatitis(SCORAD) index were used to assess the symptoms. Results : On August 30, 2021, her intestinal symptoms improved. The left tympanum was recovered to normal condition as the treatment continued. The effusion disappeared on October 16th, 2021. On November 6th, 2021, peritympanic blood congestion also almost alleviated. Subjective symptoms including aural fullness, hearing loss, and tinnitus disappeared on October 16, 2021. Nasal symptoms and dry skin also improved. The SCORAD index dropped from 15 to 4. Conclusions : These results suggests that otitis media with effusion can be sufficiently managed by Korean medicine therapy. Further, active application of Korean medicine therapy to common otolaryngological diseases is necessary.

Objectives : Horse oil (HO) has been used long time as the folk medicine of many Asian countries such as Korea, Mongol, China, India and Japan. HO has been used for anti-bacterial, anti-inflammatory, and anti-pruritic purposes in skin. However, it is still largely unknown whether HO modulates the skin condition. In this study, we attempted to evaluate the anti-inflammatory effect of HO on the 1 % of 2, 4-dinitro-1-chlorobenzene (DNCB)-induced contact hypersensitivity in Balb/c mice. Methods : To find the anti-inflammatory effect of HO, contact hypersensitivity, a local inflammatory response of skin, was induced on the back of Balb/c mice by sensitization and repeated application by 1% DNCB and HO treated 2 weeks on the 1% of DNCB-treated Balb/c mice. Excised mice skins were stained with hematoxylin and eosin and serum IgE level was measured by mouse IgE ELISA kit. Results : In this study, we found that HO reduced erythema by 1% of DNCB treated Balb/c mice. Also, HO recovered histopathological features such as the thickening of epidermis, hyperkeratosis and the infiltration of inflammatory cells in 1% of DNCB treated Balb/c mice. In addition, HO reduced IgE level on the serum obtained from blood of 1% of DNCB-treated Balb/c mice. Conclusion : Taken together, these results showed that HO could be used as a pharmaceutical material with anti-inflammatory effects by reducing of erythema, IgE level and recovering of histopathological features skin on DNCB-induced contact hypersensitivity in Balb/c mice model.

Objectives : Paeonia lactiflora Pallas (PLP) have been reported to have pharmacological effects such as anti-inflammatory and analgesic. However, it is not yet known whether PLP extract has anti-inflammatory effect on HaCaT cells, human keratinocyte. Methods : To confirm the anti-inflammatory effect of PLP on keratinocyte, TNF-𝛼/IFN-𝛾-stimulated HaCaT cells were used. HaCaT cells were pre-treated with PLP for 1h before stimulation with TNF-𝛼/IFN-𝛾. Then HaCaT cells were stimulated with TNF-𝛼/IFN-𝛾 for 24 h, the cells and media were harvested to measure the inflammatory cytokines levels. Granulocyte-macrophage colony stimulating factor (GM-CSF), monocyte chemoattractant protein-1 (MCP-1), interleukin 1 beta (IL-1𝛽), and TNF-𝛼 were analyzed by enzyme-linked immunosorbent assay (ELISA), and the mRNA expression of thymus and activation-regulated chemokines (TARC), IL-6, and IL-8 were measured by reverse transcription-polymerase chain reaction (RT-PCR). We also investigated the inhibitory mechanism of the mitogen-activated protein kinase (MAPKs) including ERK, JNK, and p38 and nuclear factor-kappaB (NF-𝜅B) by PLP using western blot. Results : PLP did not show cytotoxicity in HaCaT cells. In TNF-𝛼/IFN-𝛾-stimulated HaCaT cells, PLP significantly inhibited the expression of GM-CSF, MCP-1 IL-1𝛽, TNF-𝛼, TARC and IL-6. PLP inhibited the phosphorylation of ERK and translocation of NF-𝜅B into the nucleus. Conclusions : These results indicate that PLP could ameliorate the TNF-𝛼/IFN-𝛾-stimulated inflammatory response through inhibition of MAPK and NF-kB signal pathway. This suggests that PLP could be used beneficial agent to improve skin inflammation.

본 연구에서는 참당귀(Angelica gigas Nakai)의 핵심 유효 성분인 decursin과 decursinol angelate를 높은 수율로 추출한 초임계 이산화탄소 선택 추출물의 항염증 효능을 에탄올 추출물과 비교하여 측정하였다. 항염증 효능을 측정하기 위해 염증 매개 인자인 nitric oxide(NO), 염증성 사이토카인인 interleukin(IL)-6, IL-8 생성량을 측정하였다. NO 생성량은 lipopolysaccharide(LPS)로 염증 반응을 유도한 Raw 264.7 세포를 대상으로 Griess assay를 통해 측정하였고, IL-6 및 IL-8 생성량은 tumor necrosis factor(TNF)-α로 염증 반응을 유도한 human keratinocyte cell line(HaCaT) 세포를 대상으로 enzyme-linked immunoadsorbent assay(ELISA)를 통해 측정하였다. NO 생성량은 초임계 이산화탄소 추출물이 에탄올 추출물에 비해 뛰어나게 억제하였다. IL-6 및 IL-8 생성량 또한 에탄올 추출물은 오히려 증가시키는 반면, 초임계 이산화탄소 추출물은 6.25 ㎍/mL의 농도에서 통계적으로 유의하게 억제하였다(P<0.01). 우리는 이러한 결과를 통해 참당귀 초임계 이산화탄소 선택 추출물이 아토피 피부염을 완화시키는 항염증 코스메슈티컬 소재로써 활용 가능함을 확인하였다.
