  • Behcet's disease is a complex multisystem disease that features recurrent aphthous stomatitis, recurrent genital ulcerations, and eye lesions(uveitis or chorioretinitis). Among the systemic manifestations, pulmonary involvement is known to be rare and only a few cases have been documented. The most important features of pulmonary lesions in Behcet's disease are recurrent hemoptysis, which is often massive, and fatal pleuritic chest pain and recurrent high fever and fleeting nature of the pulmonary infiltrates. We report a case of Behcet's disease manifestated as high fever and pleural effusions which was complicated by pulmonary infarction as a result of pulmonary arteritis.

  • Postcardiac injury syndrome (PCIS) is an inflammatory process that usually occurs within 1 to 6 weeks after an injury to the pericardium, epicardium, or myocardium. As more interventions are performed for complicated coronary artery obstructive lesions, there have been some recent reports on PCIS following percutaneous coronary intervention (PCI). The medical management of PCIS depends on nonsteroidal anti-inflammatory drugs (NSAIDs), in addition to colchicine or steroids. An 80-year-old male patient underwent a PCI. Unfortunately, the guidewire piercing failed but he showed no immediate signs of complication. However, 5 hours after the procedure, he complained of chest discomfort. An electrocardiogram showed widespread ST elevation. Chest X-ray and computed tomography showed pulmonary congestion with pleural effusion, while thoracic echocardiography showed a moderate amount of pericardial effusion. NSAIDs were initiated, but there was no improvement of symptoms. We describe an unusual case of atypical earl onset PCIS after PCI, recovered rapidly by steroids.

  • Purpose : The purpose of this study was to evaluate the prescription pattern of NSAIDs and GPAs in the arthritis patients over 65 years old to prevent the GI adverse events. Nonsteroidal anti-inflammatory drugs (NSAIDs) are the most commonly used agents to treat arthritis, can cause gastrointestinal (GI) adverse effects. Recent guidelines recommend that moderate risk patients who have one or two risk factors, should be prescribed either combination of non-selective NSAID (nsNSAIDs) and gastroprotective agent (GPAs) or selective NSAID alone. Methods : Study population was National Patient Sample of 2011. Number of drugs used were 138 for NSAIDs and 21 for GPAs. Chi-square test was used to compare prescribing patterns. Results : The appropriate prescription rate follows the guideline was 11.2%: co-prescription with nsNSAID and proton pump inhibitor (PPI) or misoprostol was 1.6% and selective NSAID alone was 9.6%. Inappropriate prescription rates were as follows: co-prescription with nsNSAID and Histamine-2 receptor antagonist (H2RA) or antiacid was 53.8% and nsNSAID alone was 35.0%. The appropriate prescription rate among the types of medical institute was 54.4% in tertiary hospital, 31.2% in secondary hospital, and 6.0% in primary hospital. The appropriate prescription rate among the regions was 19.4%, highest in Seoul and 4.2%, lowest in Jeju. The appropriate prescription rate among the medical departments was as follow: 12.2% in orthopaedic surgery, 11.0% in internal medicine, and 7.7% in other departments. Conclusion : This finding suggests the needs to revise the national medical insurance imbursement policy, provide continuing medical education about the guideline of medical doctors.

  • This study was designed to determine the activities of Rosa davurica Pall. leaf extract and their regulatory mechanisms in macrophage inflammation. Anti-inflammatory potential of Rosa davurica Pall. leaf extract was evaluated by measuring the nitric oxide (NO) release and inducible nitric oxide synthase (iNOS) synthesis in lipopolysaccharide (LPS)-treated macrophage Raw 264.7 cells. Rosa davurica Pall. leaf extract potently inhibited LPS-induced NO release in a dose dependent manner. However, cell viability decreased to about 50% at high dose of 500 ㎍/ml, resulting in cytotoxicity. LPS-induced iNOS protein expression was also reduced significantly after treatment with Rosa davurica Pall. leaf extract. Furthermore, extract of Rosa davurica Pall. attenuated LPS-mediated phosphorylation of IκB and nuclear factor (NF-κB). Suppression of NF-κB signaling by treatment with PDTC, an NF-κB specific inhibitor, accelerated the inhibition of NO production and iNOS protein expression. These results suggest that Rosa davurica Pall. exhibits the anti-inflammatory potential in LPS-induced macrophage inflammation, partly through inhibition of NO production by down-regulation of NF-κB signaling.

  • The enhancement effects of sea mustard extract (SME), starfish collagen peptide (SCP) and a mixture of the two (MIX) on skin activity were evaluated to investigate the possibility of using marine-derived extracts as cosmetic additives. The anti-inflammatory activity, whitening activity and skin elasticity activity of the extracts were analyzed to evaluate their skin-activating effects. Inhibiting the generation of nitric oxide (NO) and the tyrosinase and elastase inhibitory activities were assessed as the bio-markers for evaluating skin activity. SME, SCP and MIX did not show cytotoxicity within the concentration range of 1.0-50 ㎍/mL. In addition, SME, SCP and MIX all increased NO production and the tyrosinase and elastase inhibitory activities in a concentration-dependent manner. The activity of MIX was significantly increased compared to that with using SME or SCP alone. Taken together, when natural extracts are applied as cosmetic additives, the results demonstrate that using a mixture of SME and SCP may have a greater synergistic effect than that when using only a single extract. Therefore, this study contributes to the knowledge about the kinds and composition of several natural extracts when they are used as cosmetic additives.

  • 영지의 약리효과는 triterpenoid계의 저분자와 polysaccharide인 고분자로 대별할 수 있다. 저분자 물질은 항염증작용, 항알러지작용, 간암세포 성장 억제작용, 혈압 강하작용, 혈소판 응집저해작용 등이 있으며, 고분자 물질은 혈압강하작용, 정혈작용, 고지혈증 개선작용, 혈당 강하작용, 면역 증강작용 및 항종양작용 등이 있는 것으로 알려졌다. 현재까지의 영지에 관한 연구는 주로 자실체에 대한 연구가 주류를 이루고 있으며 이들의 산지, 환경조건, 채집시기 및 실험자들에 따라 약리 효과 등에 많은 차이가 있다. 이들에 대한 효과가 영지의 대표적 약리효과라고 언급하기엔 부족한 점이 많으므로 약리효과가 우수하고 일관성이 있는 영지 유래 다당류를 얻기 위한 방법으로서는 균사체의 대량배양법 및 분리방법이 확립 되어야만 한다. 본 연구에서는 새로운 항암활성 다당류의 개발을 위해 국내 자생 영지를 채집하여 검색 및 계통적 분류를 행하였으며 분리된 균주의 최적 액체배양 조건, 다당류 분리 조건, 다당류의 물리화학적 특성 및 약리활성 등에 관한 연구를 실시하였다. 그 중 약리활성이 우수한 G- lucidum IY009 균주를 선발 하였다. 구조적 특징과 종양 면역 활성과의 관계 규명을 위해, G- lucidum IY009 배양균사체로부터 다당류를 T-AS, U-AS, M-AS, S 및 H로 분획 하였다. 추출조건에 따른 다당류 GLG의 수율은 열수 추출 분획이 2.98g/l로 가장 높았으며, U-AS및 T-AS에서 각각 2.32g/l, 2.07g/l이었다. GLG의 특성을 조사하기 위하여 수용성과 비수용성으로 분리한 결과 수용성 분획은 비수용성 분획보다 높은 당 함량을 나타냈으며, T-AS는 70.3%의 당과 7.8%의 단백질로 구성 되었다. GLG 대부분의 분획들은 60~93%의 glucose로 구성된 다당류 이었으며, 주로 $\beta$-glucose로 구성된 다당류 이었다. 아미노산은 Asp 및 Glu의 산성 아미노산과 Ala, Leu 등의 함량이 높게 나타났으며, 비알칼리 추출물에서 Ser과 Thr의 함량이 높게 나타났다. 다당류 T-AS는 평균 분자량이 2,000 kD와 12kD에서 주 peak를 나타냈으며, 수용성 분획의 평균 분자량은 12kD이고 비수용성 분획은 36~2,000 kD의 평균 분자량 분포를 갖는 것으로 나타났다. IR과 NMR 분석 결과 890 cm-1에서 흡수 peak를 나타내어 $\beta$-(1,3)0glucan과 $\beta$-(1,6)-glucan의 구조를 갖는 다당류로 확인 되었다. T-AS 분획은 C:H:O:N의 함량비가 38.9:5.7:49.6:1.84%이며, 이 물질의 융점은 163 $^{\circ}C$로 연한 갈색을 나타낸다. 분리된 GLG의 항암활성 기전 규명을 위해, in vivo 항암실험, 항보체 활성능, 항체 생성능, serum protein 분비능, 대식세포의 탐식능과 활성능 및 세포간 물질 분비 등의 상관관계를 조사하였다. 다당류 GLG 분획물들 가운데 항보체의 활성이 높았던 분획은 sarcome 180에 대한 항암 활성이 높게 나타났다. 다당류 T-AS의 보체 활성화 기작은 classical과 alternative complement pathway의 양 경로를 통해 활성화 되었다. T-AS 분획은 mouse내의 특정 혈청단백을 증가시켰으며, 항체 생성능의 증가가 관찰되어 effect T 세포의 활성화가 나타나고 있음을 알 수 있었다. T-AS는 생체내 투여시에 대식세포의 탐식능이 증진되었으며, 대식세포 기능 저해제에 의한 대식세포의 기능 저해 현상이 회복되었다. 이와 같은 결과들로부터, T-AS의 항암 활성은 활성화된 보체 성분 및 당 수용체들이 존재하는 대식세포의 개입을 시사한다.

  • Alkyl ethoxy sulfate type surfactants, widely used in commercial cleansers, are easily adsorbed to skin to often cause skin irritation and inflammation if not thoroughly rinsed nut. In order to replace or complement existing surfactants, we screened the existing surfactants through protein denaturation method, cell cytotoxicity assay and human IL-1$\alpha$ assay, etc. Fourteen surfactants have been chosen from among too irritant anionic, cationic and/or zwitter-ionic ones and investigated for cell cytotoxicity in human fibroblast cell lines using monolayer culture with the thirteen commercially available cleansers for sensitive skin. From these results, we selected 5 surfactants and 2 commercial cleansers (names not shown), such as sodium laureth sulfate (anionic), sodium cocoyl isethionate (anionic), sodium lauroamphoacetate (zwitter-ionic), and cocamidopropyl betaine (zwitter-ionic), alkyl polyglycoside (non-ionic). 20 formulations were made out of 5 surfactants and five of them were chosen through a protein denaturation method (lower than 3 M sodium dodecyl sulfate solution ($13.2\%$)), cell cytotoxicity and human patch test. These five selected formulations containing preservatives were compared to two selected commercial cleansers by cell cytotoxicity and human IL-1$\alpha$ ELISA assay using dermal equivalent. Finally, we selected the best formulation. To this formulation, fructan ($3\%$ or $5\%$) or/and portulaca extract ($3\%$ or $5\%$) well known for its anti-inflammatory and moisturizing effects were added and investigated for cell cytotoxicity using dermal equivalent. In cytotoxicity assay using dermal equivalent, two formulations containing $5\%$ fructan and $3\%$ or $5\%$ portulaca extract were less toxic than the others. In cytotoxicity assay and human IL-1$\alpha$ ELISA using 3D culture, the selected formulation containing $5\%$ fructan and $5\%$ portulaca extract showed better efficiency than those of the others and 2 commercial cleansers. As a result, we could develop a low irritant and safe liquid cleanser.

  • Hemp seed (Cannabis sativa L.; HS), an annual herbaceous plant in the Cannabis genus, has been reported to play various biological functions in immunity increase, atherosclerosis, constipation, hyperlipidemia prevention, anti-inflammatory, and anti-cancer. In recently years, as superfood, the growing interest in the health care benefits of hemp seed has led to increased consumption. In this study, we investigated the effect of an ethanol extract of HS fermented with lactic acid bacteria (Lactobacillus plantarum KCTC 3107, L. plantarum KCTC 3108, L. brevis BHN-LAB128, L. paracasei BHN-LAB129). An antibacterial activity against Staphylococcus aureus and Bacillus cereus were 13.99 mm and 15.17 mm, respectively. The ethanol extracts of fermented hemp seed by lactic acid bacteria that the contents of total polyphenol, total flavonoid content, DPPH radical scavenging activity, SOD-like activity, and ${\alpha}$-glucosidase inhibitory activity were increased compared to non-fermented hemp seed. Also, tyrosinase inhibitory activity of the fermented hemp seed (FHS), known to melanin increasing substance was increased. In these results, we suggested that FHS have effects of anti-oxidant, ${\alpha}$-glucosidase inhibitory activity, and tyrosinase inhibitory activity. Hence, we proposed that FHS has possible to development as functional foods and cosmetics.

  • The succulent plant Aeonium sedifolium leaves contain several compounds that are of interest for their cosmetic uses on the skin. This study measured the inhibitory effects of enzyme production and antioxidant, astringent effects and skin wrinkles using Aeonium sedifolium leaves (ASL). The total phenolics compounds (TPC) content of ASL under optimal extraction conditions was 34.49 mg/g for hot water extract (ASLW) and 61.64 mg/g for 50% ethanol extract (ASLE). The ASLW and ASLE extracts were freeze-dried, powdered, and used as solids. TPC content, 2,2-diphenyl-1-picrylhydrazy (DPPH) radical scavenging activity, and 2,2'-azinobis (3-ethylben-zothiazoline 6-sulfonate) (ABTS) radical inhibition of the ASL phenolics were tested. The DPPH radical scavenging activities of ASLW and ASLE were tested at a TPC of 100 ㎍/mL. ABTS radical inhibition showed antioxidant activity of 100.00% in ASLW and ASLE, and the antioxidant protection factor of ASLW and ASLE was 1.07 and 1.22, respectively. The thiobarbituric acid-reactive substance (TBARS) inhibitory activity of ASLW and ASLE was 77.00%. The elastase inhibitory activity of ASLE was 69.03%, and collagenase inhibition activity for ASLW and ASLE was 29.82% and 54.76%, respectively. The astringent effect of ASLE was 89.82% at a TPC of 200 ㎍/mL. Thus, we concluded that ASL has the potential as a functional cosmetic ingredient with anti-aging effects on the skin.

  • Mesenchymal stem cells (MSCs) are an attractive resource for refractory patients because of their anti-inflammatory/immunomodulatory capability and multi-lineage differentiation potential. The transplantation of MSCs has led to positive results in preclinical and clinical application to various diseases, including autoimmune disease, cardiovascular disease, cancer, liver cirrhosis, and ischemic stroke. On the other hand, studies have shown that paracrine factors, not direct cell replacement for damaged cells or tissue, are the main contributors in MSC-based therapy. More recently, evidence has indicated that MSC-derived exosomes play crucial roles in regulating the paracrine factors that can mediate tissue regeneration via transferring nucleic acids, proteins, and lipids to the local microenvironment and cell-to-cell communication. The use of these exosomes is likely to be beneficial for the therapeutic application of MSCs because their use can avoid harmful effects, such as tumor formation involved in cell transplantation. Therefore, therapeutic applications using MSC-derived exosomes might be safe and efficient strategies for regenerative medicine and tissue engineering. This review summarizes the recent advances and provides a comprehensive understanding of the role of MSC-derived exosomes as a therapeutic agent.
