  • Objectives : This study aimed to assess the scientific evidence for the use of Hwanglyeonhaedok-tang, a traditional herbal formula, in the treatment of rhinitis, and prepare the basis for the investigational new drug application by analyzing the experimental studies. Methods : Ten electronic databases were searched up to December, 2016 without language limitation. Experimental studies on the anti-inflammatory and anti-allergic effects of Hwanglyeonhaedok-tang against rhinitis were included. We extracted data about study design, characteristics of intervention, outcomes, and pharmacological effects from the included studies and summarized them. Results : Eight hundred and thirty-three potentially relevant studies were identified, of which 18 experimental studies met our inclusion criteria. Of 18 included studies, 5 had conducted cell viability test, and all studies had reported that Hwanglyeonhaedok-tang was non-cytotoxic. Hwanglyeonhaedok-tang exhibits anti-inflammatory effect by regulating the inflammation-related cytokines including nitric oxide(NO), prostaglandin $E_2(PGE_2)$, interleukin-6(IL-6), and tumor necrosis $factor-{\alpha}(TNF-{\alpha})$ in vitro and in vivo. Hwanglyeonhaedok-tang exhibits anti-allergic effect by suppressing eosinophil, and histamine levels. Hwanglyeonhaedok-tang helps in the recovery of nasal mucous membrane by supressing goblet cells, heat shock protein 70, and substance P. Conclusions : This study suggests that Hwanglyeonhaedok-tang has the potential to be developed as therapeutic agent for rhinitis. Further experimental and clinical studies needed to be performed to prove the safety and efficacy.

  • Background: Periodontal disease, also known as gum disease, is a major dental inflammatory disease with a very high prevalence; it is the main cause of tooth loss. Therefore, diagnostic biomarkers that can monitor gum inflammation are important for oral healthcare. Since the gingival crevicular fluid (GCF) adequately reflects changes in the periodontal environment, they have become a target for the development of effective diagnostic biomarkers for periodontitis. In the present study, the level of the target molecules suggested as diagnostic biomarkers for periodontitis were analyzed in GCF samples collected from healthy individuals and periodontitis patients. In addition, useful targets for the diagnosis of periodontitis were evaluated. Methods: GCF samples were collected from healthy individuals and periodontitis patients using absorbent paper points. SDS-PAGE and Coomassie staining were performed for protein analysis. The protein concentrations of GCF specimens were determined using the Bradford method. The levels of the target molecules appropriate for diagnosing periodontal disease were measured by ELISA, according to the manufacturer's protocol. Results: The protein concentration of GCF collected from periodontitis patients was 3.72 fold higher than that in an equal volume of GCF collected from healthy individuals. ELISA analysis showed that the level of interukin-6 (IL-6), IL-8, metalloproteinases 2 (MMP-2), MMP-9, tumor necrosis factor-alpha (TNF-α), azurocidin, and odontogenic ameloblast-associated protein (ODAM) were higher in the GCF samples from the periodontitis patients than in those from the healthy individuals. However, the level of IL-6 and TNF-α were relatively low (> 5 pg/ml). The prostaglandin E2 (PGE2) levels were not significantly different between the two GCF samples. Conclusion: These results indicate that IL-8, MMP-2, MMP-9, azurocidin, and ODAM are potentially useful diagnostic biomarkers for periodontitis; combining multiple biomarkers will improve the diagnostic accuracy of periodontitis.

  • Objectives : In cases of osteoarthritis, the hypofunction of the cartilage and joint leads to a limited range of joint motion, swelling, and pain, which is generally treated using pharmaceutical drugs (e.g., anti-inflammatory agents, cartilage protectants, and nonsteroidal anti-inflammatory drugs) or replacement arthroplasty. However, long-term drug treatment is associated with adverse effects on the gastrointestinal systems. The present study aimed to evaluate the ability of Giheolsotong-hwan to treat of osteoarthritis symptoms in the MIA-induced rat model based on histological analysis, and factors that are associated with inflammation and bone mineral metabolism. Methods : Giheolsotong-hwan was administered orally at doses of 200 mg/kg/day or 400 mg/kg/day for 2 weeks before direct injection of monosodium iodoacetate ($3mg/50{\mu}{\ell}$ of 0.9% saline) into the intra-articular space of the rats' right knee. The rats subsequently received the same doses of oral Giheolsotong-hwan for another 4 weeks. We evaluated the treatment effects based on serum biomarkers and histopathological analysis of the knee joints. Results : Compared to those in control rats, the Giheolsotong-hwan treatments significantly decreased the serum concentration of inflammation factors (i.e., $IL-1{\beta}$, IL-6, $TNF-{\alpha}$, $PGE_2$, and $LTB_4$), and bone degrade factors (i.e., MMP-9, CTX-II, and COMP). In addition, the Giheolsotong-hwan treatments significantly increased the concentration of glycosaminoglycans of bone defence factors, but no chage the TIMP-1. Furthermore, the Giheolsotong-hwan treatments effectively preserved the knee cartilage and proteoglycan. Conclusion : The results indicate that Giheolsotong-hwan treated osteoarthritis symptoms. Thus, Giheolsotong-hwan may be a novel oriental therapeutic option for the management of osteoarthritis.

  • Although hypoxic/ischemic injury is thought to contribute to the incidence of Alzheimer disease (AD), the molecular mechanism that determines the relationship between hypoxia-induced β-amyloid (Aβ) generation and development of AD is not yet known. In this study, we investigated the protective effects of Acorus gramineus Soland. (AGS) on oxygen-glucose deprivation/reoxygenation (OGD/R)-induced A β production in SH-SY5Y human neuroblastoma cells. Pretreatment of these cells with AGS significantly attenuated OGD/R-induced production of reactive oxygen species (ROS) and elevation of levels of malondialdehyde, nitrite (NO), prostaglandin E2 (PGE2), cytokines (TNF-α, IL-1β and IL-6) and glutathione, as well as superoxide dismutase activity. AGS also reduced OGD/R-induced expression of the apoptotic protein caspase-3, the apoptosis regulator Bcl-2, and the autophagy protein becn-1. Finally, AGS reduced OGD/R-induced Aβ production and cleavage of amyloid precursor protein, by inhibiting secretase activity and suppressing the autophagic pathway. Although supporting data from in vivo studies are required, our results indicate that AGS may prevent neuronal cell damage from OGD/R-induced toxicity.

  • 본 연구의 목적은 발효차 중에 미량물질로 존재하는 purpurogallin 유도체의 항염증에 대한 효과를 검토하고자 실시하였다. 특히 발효차에 존재하는 미량 성분들에 대한 생리활성 연구보고는 많지 않은데 이러한 이유는 미량성분을 기술적으로 발효차로부터 분리 정제하기가 매우 어렵기 때문으로 판단된다. 특히 녹차잎에 존재하는 페놀 화합물중 하나인 gallic acid는 발효과정 중 benzotropolone 구조를 가지는 purpurogallin 유도체를 새롭게 만드는 것으로 알려져 있는데 본 연구에서는 gallic acid 화합물이 이러한 과정 중에 생성하는 산화물을 효소적 산화 모델시스템인 peroxidase/hydrogen peroxide 모델을 이용하여 산화물을 얻은 후 컬럼크로마토그라피법을 이용하여 순수 분리하였다. 이 과정에서 purpurogallin carboxylic acid(PCA)를 gallic acid의 산화물로 분리할 수 있었고 이의 구조를 $^{1}H$ NMR, $^{13}C$ NMR 및 MS 분석방법을 이용하여 확인할 수 있었다. 이후 단리되어진 PCA의 항염증 효과를 검토하였다. RAW264.7 세포를 이용하여 PCA의 항염증 효과를 검토하였는데 PCA 100, 75, $50{\mu}g/mL$ 처리는 NO의 생성을 LPS만 처리한 세포에 비해 각각 57.6, 41.5, 21.8%를 유의적으로 저해시키는 것으로 나타났다. PCA 100, $75{\mu}g/mL$ 처리군에서 LPS만 처리한 RAW264.7 세포에 비해 IL-6의 생성이 각각 43.1, 23.9% 억제되어지는 것으로 관찰되었다. 또한 유사한 경향으로 PCA 100 및 $75{\mu}g/mL$ 처리군에서 LPS만 처리한 RAW264.7 세포에 비해 $PGE_2$의 생성이 각각 29.0% 및 15.4% 억제 되어지는 것으로 관찰되었다. 최근 생리활성을 가지는 신물질의 탐색 및 신소재 개발의 중요성이 부각되고 있다. 특히 선진국의 신물질의 개발에 의한 물질 특허가 증가하고 있고, 이에 따라 국내에서도 국제 경쟁력을 확보하기 위한 새로운 소재 개발이 시급한 상황이다. 본 연구 결과는 gallic acid의 산화물인 purpurogallin 유도체를 이용한 항염증 소재의 적용 가능성을 검토한 주요한 결과로 사료되어진다. 또한 본 연구를 통하여 발효차에 미량으로 존재하는 화합물들의 생리활성을 확인할 수 있었으며, 발효차에 포함되어 있는 미량 성분들의 항염증 관련 신소재 개발 가능성을 검토할 수 있었다.

  • To investigate the difference and change of ingredient and efficacy of Galgeun-tang (GGT) according to extraction solvent, water and 70% EtOH, the quantities of index components and the several in vitro activities of two kinds of GGT extract were compared. The contents of extracts were analyzed with HPLC. The biological activities such as anti-inflammatory and anti-obesity effects were measured through cell line-based in vitro assay. The cytotoxicity was measured by CCK-8 assay in RAW 264.7 cell, BEAS-2B cell, HaCaT cell and 3T3-L1 cell. We compared effects of two kinds of extract by measuring NO, PGE2, IL-6 and TNF-${\alpha}$ in RAW264.7 cell, RANTES in BEAS-2B cell, MDC and RANTES in HaCaT cell and GPDH activity and leptin level in differentiated 3T3-L1. 70% EtOH extract of GGT contained more compositions than water extract. The inhibitory effect of water extract of GGT on NO in RAW 264.7 cell and GPDH activity in 3T3-L1 was stronger than that of 70% EtOH. 70% EtOH has a stronger inhibitory effect on PGE2 in RAW264.7 cell, RANTES in BEAS-2B cell, MDC, RANTES in HaCaT cell, leptin in 3T3-L1 cell than water extraction. These results suggest that the ingredient and efficacy from 70% EtOH extract of GGT are more effective than water extract.

  • 본 연구에서는 보행훈련 전후에 실시된 보행속도 측정 결과와 누운 자세에서 능동적 발목 배굴시의 근전도 활동 측정 결과를 비교하였다. 9명의 불완전 척수손상 환자들이 3개월 동안 하루 20분 주 5회로 이루어진 체중부하 감소장치 및 트레드밀을 이용한 보행훈련 (STAT supper-ted treadmill ambulation training)에 참가하였다. 보행속도 실험과 능동운동 실험은 보행훈련 시작 및 종료된 시점의 동일한 날, 혹은 같은 주에 실시되었다. 환자의 능동운동시의 표면근전도 값을 측정하였고. 동일한 운동시 열명의 건강한 피실험자들로부터 측정된 근전도값을 기준값으로 비교하는데 사용하였다 하지 열곳의 근육에서 측정된 표면근전도 값은 반응벡터 (response vector)라고 명명되었고 크기 및 근육 제어 분포 패턴을 관찰하는데 사용되었다. 척수손상 환자들의 보행속도는 0.47$\pm$0.35 m/s에서 0.68$\pm$0.52 m/s로 유의한 증가를 보였다. 근전도 해석결과에서는 우측 발목관절 배굴시에 근전도의 증가를 보인 6인의 환자들의 값은 109.7$\pm$148.5 $\mu\textrm{V}$에서 145.9 $\pm$ 180.7 $\mu\textrm{V}$ 로 증가하였으나 유의한 수준은 아니었다 (p〈0.055). 또한 좌측 발목의 배굴에서 측정된 근전도에서는 단 2명만이 상관계수와 근전도 증가를 보였다 보행훈련 후의 환자들의 근육 활동의 변화는 개개인의 상태에 따라 매우 다양하게 변하였고. 보행훈련 후의 상태는 보행훈련 전의 상태에 매우 의존적임을 알 수 있었다 정량적인 해석을 위해 새로 도입된 반응벡터의 사용은 척수손상 환자들의 보행훈련 전후에 환자의 상태를 평가. 예측, 혹은 훈련의 방향 설정시에 유용하게 사용될 수 있는 가능성을 보여주었다.ne(chloroform)와 toluene 등이 가장 자주 검출되는 성분이었다. 대부분의 aromatic hydrocarbons, alkyl benzenes및 다른 유기용매 성분은 검출농도 이하이다.한 대사적인 문제와 생활 양식에 의한 영향이 클 것으로 추정된다. 그러므로 BMI가 높은 노인들에게 부족되고 있는 영양소에 대한 연구가 이루어져야 할 것이다. 특히 비타민 A, E B 복합체는 노인성 질병과 관련하여 그 기능이 규명되어야 할 영양소이다. 이는 항산화효소의 증가에 의한 지질 과산화물 생성삼소와 PGE$_2$및 TXA$_2$등의 유의적인 감소가 유선암세포의 증식을 억제하는 인자로 작용할 수 있는 가능성을 시사하였다. 또한 지방산 투여 에 따른 과산화물 생성과 항산화 시스템이 유선암 세포에서는 상호기전적으로 작용하지 않았으나 이는 농도와 배양시간에 따른 CLA의 항암효과가 in vivo 실험에서 재검증 할 필요가 있음을 시사한다. 또한 장시간의 세포배양 실험시 PGE$_2$는 반감기가 짧고 다른 대사물로 쉽게 전환되는 불안전한 물질이므로 새로운 측정방법의 개발이 필요하겠다. 더욱이 CLA에 의한 항암효과가 정확히 어떤 기전에 의한 것인지 보다 깊이 있는 연구가 필요하지만 본 연구에서 얻은 에이코사노이드 대사의 변화 등은 유선암 예방 연구에 기초적인 자료가 될 것으로 생각된다.들어가 면서 점차 감소하여 대조군과 유사한 양상을 나타내었으나, 전체적으로 대조군보다 높은 수치를 나타내었다. 반면에 5, 10 $\mu\textrm{g}$ L$^{-1}$의 농도에 노출된 세포는 초기에 매우 낮은 탄소동화율을 보였으며, 5 $\mu\textrm{g}$ L$^{-1}$의 농도에 노출시킨 세포의 경우 12일째부터 단위세포 당 탄소동화율이 매우 크게 증가하였다. 본 연구의

  • 진달래꽃으로부터 Sephadex LH-20 및 MCI gel CHP-20 column chromatography로 정제한 결과 항염증 활성을 가지는 myricetin을 분리, 동정하였다. Myricetin은 농도 의존적으로 NO 발현을 억제하였고, $50{\mu}M$ 농도에서 약 40%의 억제효과를 나타내었다. Myricetin의 iNOS와 COX-2의 발현억제력은, $25{\mu}M$ 농도에서 각각 20% 및 80%의 protein 발현 억제효과를 나타내었다. 또한 myricetin의 염증반응의 cytokine을 측정하여 $TNF-{\alpha}$, $IL-1{\beta}$, IL-6 및 $PGE_2$의 억제력을 살펴본 결과, 농도 의존적으로 발현억제 효과를 나타내었으며, $50{\mu}M$ 농도에서 각각 70%, 80%, 80% 및 95%의 발현 억제효과를 나타내었다. 따라서 진달래 꽃잎에서 분리한 myricetin은 LPS로 유도되어진 대식세포주인 Raw 264.7 세포에서 염증반응의 억제효과를 기대할 수 있었다.

  • Objectives : This study evaluated activities and ingredient contents concerning extracts according to extraction solvents of Insampaedok-san (IS, Renshen bai du-san). Methods : The herbal constituents of IS were extracted with water and 70% ethanol at $100^{\circ}C$ for 2 hr. Using the HPLC system, the six ingredient contents of different solvent extracts of IS were analyzed. The nitric oxide (NO), prostaglandin $E_2$ ($PGE_2$) production and proinflammatory cytokines were measured in RAW264.7 cells stimulated with lipopolysaccharide (LPS). The macrophage-derived chemokine (MDC/CCL22) and regulated on activation normal T-cell expression and secreted (RANTES/CCL5) production were measured in HaCaT and BEAS-2B cells stimulated tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) and interferon-${\gamma}$ (IFN-${\gamma}$). The activities of glycerol-3-phosphate dehydrogenase (GPDH) and leptin level were measured in 3T3-L1 cells. Results : The calibration curves showed good linearity ($r^2$=1.0000) for different concentration ranges. The contents of liquiritin, naringin, hesperidin, neohesperirin and glycyrrizin in 70% ethanol extracts of IS were relatively higher than that of water extract, however the content of ferulic acid in 70% ethanol and water extract of IS were similar. The extraction solvents of water and 70% ethanol were evaluated inhibitory effect on the production of NO, $PGE_2$, TNF-${\alpha}$ and IL-6 in RAW 264.7 cells. Their extractions were inhibitory effect on production of MDC/CCL22 and RANTES/CCL5 in HaCaT cell and BEAS-2B cell, respectively. In addition, evaluated reduced on GPDH activity and leptin level in 3T3-L1 preadipocyte cell. Conclusions : Our results suggest that IS extracts were inhibitory effects of disease such as inflammation, allergies and obesity.
