  • 녹용은 강심작용, 여성홀몬작용, 강장작용, 창상치유작용 등의 약리작용이 있는 것으로 보고되어 있는데 녹용의 상용량에서는 강장작용, 창상치유작용이 있는 것으로 알려져 있다. 녹용의 창상치유작용은 생체내 질소 평형이 음의 방향으로 되었을 때 이를 빠른 시간내에 정상적으로 회복시키는 약리효과에 기인하는 것으로 볼 수 있겠다. 본 연구에서도 흰쥐에 turpentineee oil (TPO)를 주사하여 acute-phase response를 일으켜 질소평형을 깨뜨린 실험 모델에서 녹용의 효과를 측정하였다. Acute-phase reactants중에서 $\alpha$$_2$-macroglobulin, $\alpha$$_1$-cysteine pretense inhibitor (T-kininogen), ceruloplasmin을 측정 하였는데 이 중에서 creuloplasmin의 측정이 재현성이 높았다. TPO로 급성염증을 유발시키면 2일 후에 ceruloplasmin의 혈청내 농도가 약 100% 증가하며 4일까지 지속하다가 5일째부터 감소하는데 이때 미리 녹용추출물을 투여한 군은 TPO주사 후 4일째에 50% 감소하였다. TPO로 염증을 유발하기 전에 녹용을 투여했을 때가 염증유발 후에 투여했을 때보다 녹용의 효과가 현저히 나타났다. 이러한 결과는 급성염증에 의해 깨어진 단백질 평형을 신속히 정상화시키는 효과가 있음을 나타내는 것으로 이러한 녹용의 효과를 지표로 하여 녹용의 유효성분 분리를 수행하고자 한다.

  • When inflammatory reaction is in progress, the macrophages release inflammatory cytokines, such as interleukin-6 (IL-6), tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), and product inflammatory mediators, including inducible nitric oxide synthase (iNOS) and prostaglandin E2 (PGE2). We conducted this study to evaluate the anti-inflammatory efficacy on each water extract of Acanthopanacis cortex, Achyranthes radix, and Eucommiae cortex, and to investigate whether they inhibit the expression of pro-inflammatory cytokine. Acanthopanacis cortex, Achyranthes radix, and Eucommiae cortex were extracted with water and freeze-dried. Acanthoside D, 20-hydroxyecdysone, and pinoresinol diglucoside as an index material were analyzed by high-performance liquid chromatography (HPLC) to ensure that the components of each extracts were extracted well. RAW 264.7 cell line, stimulated with lipopolysaccharide (LPS) to cause an inflammatory response, was treated with each water extract at various concentrations to determine the anti-inflammatory efficacy. Then, the anti-inflammatory efficacy was confirmed by a nitric oxide (NO) assay, and the mRNA expression levels of pro-inflammatory cytokines were measured by real time PCR. As a result, the indicator materials were detected from each extract, and Acanthopanacis cortex water extract (ACWE) and Achyranthes radix water extract (ARWE) were shown to have a high activity than Eucommiae cortex water extract (ECWE) in NO assay. In Korea, traditionally it prescribed a combination of medicinal herbs. This study confirmed the anti-inflammatory response of these medicinal plants in arthritis and its synergistic effect when used in combination with western medicine.

  • Purpose : Though atopic and nonatopic asthma have different clinical manifestations, bronchial hyperresponsiveness (BHR) and airway inflammations are common characteristics of them. We investigated BHR to both methacholine and adenosine 5'-monophosphate (AMP), and their relationships with blood eosinophil markers in nonatopic asthma as well as atopic asthma. Methods : We studied 116 children (82 atopics; 34 nonatopics) with mild to moderate asthma. Methacholine and AMP challenge tests were performed and bronchial responsiveness was expressed as $PC_{20}$ (provocative concentration causing a 20 percent fall in $FEV_1$); blood eosinopil counts (ETCs) and serum eosinophil cationic protein (ECP) levels were gauged. Results : In atopics, 95.1 percent and 90.2 percent showed hyperreactivity to methacholine ($PC_{20}$<16 mg/mL) and AMP ($PC_{20}$<200 mg/mL), respectively. Meanwhile, in nonatopics, 94.1 percent and 52.9 percent displayed hyperreactivity to methacholine and AMP, respectively. The geometric mean of AMP $PC_{20}$ was lower in atopics (31.6 mg/mL) than in nonatopics (125.9 mg/mL); that of methacholine $PC_{20}$ was similar in the two groups. AMP $PC_{20}$ correlated with blood ETCs in both atopics(r=-0.30, P<0.01) and nonatopics (r=-0.57, P<0.01), and correlated with serum ECP levels (r=-0.23, P<0.01) in atopics, but not in nonatopics. Apart from AMP, methacholine $PC_{20}$ was not associated with blood eosinophil markers in either group. Conclusion : Atopics more frequently displayed BHR to AMP than nonatopics. Furthermore, BHR to AMP was associated with not only blood ETCs, but serum ECP levels in atopics but was correlated with only blood ETCs in nonatopics. Those results suggest that BHR to AMP reflects airway inflammation in asthma and is more related to atopy.

  • Lathyrus palustris often used as a treatment for inflammation of the kidneys in Korean traditional medication. Generally, drugs for arthritis have anti-inflammatory and antinociceptive properties. However, the validity of the anti-inflammatory effect has not been scientifically investigated so far. Therefore, the purpose of the research was to investigate the latent anti-inflammatory ability of L. palustris using the ethanol extract. To evaluate the anti-inflammatory activities, we examined the inflammatory arbitrators such as a nitric oxide (NO) and prostaglandin E2 (PGE2) on RAW 264.7 cells. Our results indicated that ethanol extract significantly inhibited the lipopolysaccharide E (LPS) derived PGE2 production in RAW 264.7 cell. The inhibitory activity of ethanol extract for PGE2 tests with inhibition ratio showed in 40 ㎍/mL. Overall, PGE2 tests had a higher inhibitory effect on inflammation than NO tests. This result anticipated that the ethanol extract from L. palustris is a good candidate for developing the origin of anti-inflammatory agents.

  • 녹용의 알려진 약리작용 중에서 녹용의 상용량 투여에 의해 나타나는 것은 강장작용과 창상치유작용이므로 이러한 작용이 진정한 녹용의 효능으로 간주될 수 있으나 이러한 작용을 생물활성 검색법으로 활용하여 녹용의 유효성분을 검색하기에는 재현성과 간편성이라는 면에서 어려운 점이 없지 않다. 녹용의 효능이 생체의 질소평형이 음의 방향으로 진행되었을 때 이를 정상 수준으로 복귀시키는 생물활성에 기인할 것이라는 가정하에서, 실험적으로 생체내 질소편형을 음의 방향으로 전환시킬 수 있는 급성기 반응 (acute-phase responce)을 야기시킨 다음 녹용의 효과를 연구하였다. 흰쥐의 급성기 반응물질 (acute-phase reactants, APR) 중에 서 positive ARP인 ceruloplasmin, $\alpha$-cysteine pretense inhibitor(= T-kininogen)는 비색정량법으로 간편하게 측정될수 있음에 착안하여 이 단백질을 지표로 삼아 turpentine oil로 급성 염증을 유발시킨 전후에 녹용 물추출액의 효과를 측정하였다. 그 결과 녹용의 상용량에서 괴소 4일 이상 경구투여한 흰쥐에서 급성 염증유발 후 4일에서 ceruloplasmin 의 혈중농도가 현저히 감소함을 알수 있었다. 급성 염증 유발후 녹용의 경구투여한 실험에서는 적어도 녹용 상용량의 3배 이상을 투여하여야 만 ceruloplasmin 혈중 농도를 감소시킬 수 있었다. 본 연구에서 수립된 생물활성을 이용하여 녹용의 유효 성분을 단리할 계획이다.

  • 본 연구에서는 침의 면역조절작용을 통한 염증반응 억제효과를 연구하기 위하여 내독소를 주입한 흰쥐의 시상하부에서 염증반응의 중추인 방실핵의 신경활성에 미치는 영향을 관찰하였다. 흰쥐의 미정맥에 LPS와 생리식염수를 각각 주입하고 군에 따라 양측 소부(HT8)나 족삼리(ST36)에 1분간 침치료를 각각 시행하였다. C-Fos는 신경활성을 자극하는 초기단계에 발현되는 유전자로서 신경계의 특정부위의 활성도를 측정하는 지표로 널리 사용되고 있다. 본 연구자는 침자극이 LPS로 인한 염증반응에 미치는 영향과 그 기전을 알아보기 위해 면역조직화학염색의 방법을 이용하여 대뇌 시상하부의 방실핵에서 c-Fos 면역활성을 측정하였다. LPS를 주입한 군의 방실핵에서 생리식염수를 주입한 군에 비해 c-Fos 면역활성이 유의하게 증가한 반면 소부에 자침했을 때 LPS에 의해 증가된 c-Fos 면역활성이 유의하게 감소하였다. 족삼리에 자침한 군에서는 유의한 변화가 나타나지 않았다. 결론적으로 소부 침치료는 LPS로 인해 증가된 방실핵의 신경활성을 효과적으로 감소시켰고 이는 침의 면역조절 및 탁월한 염증억제 효과를 보여주는 결과일 뿐 아니라 침의 인체 항상성 유지를 통한 치료기전에 대한 향후 연구의 중요한 실마리를 제공해주고 있다고 사료된다.

  • Background : The intrapleural hypofibrinolysis is caused by mainly excessive concentration of pleural plasminogen activator inhibitor-1 antigen(PAI-1 Ag), which binds tissue type plasminogen activator. In pleural inflammation induced by sclerosing agents for pleurodesis, levels of pleural PAI-1 antigen increase in relation to decreasing D-dimer levels. It has been known that the pleural mesothelial cells have the capability of secreting PAI-1 Ag in response to inflammation in vivo. Therefore, we estimated whether pleural inflammation changes the balance between fibrinolytic and coagulative properties in exudative pleural effusions. Method : The thirty cases was included in our study. We determined the pleural levels of glucose, lactic dehydrogenase(LDH), pH and the counts of white blood cell(WBC), polymorpho leukocyte(PMN), lymphocyte as the parameters of pleural inflammation and cellular components of pleural fluid. The plasma level of fibrinogen in fluid and the neutrophil count in blood were determined. The levels of D-dimer, PAI-1 Ag and thrombinantithrombin III complex(TAT) were determined by ELISA(Behring, Marburg, Germany). Result : The causes of pleural effusion were as following : tuberculous in 14 cases, malignant in 10 cases and parapneumonic in 6 cases. The levels of pleural D-dimer, PAI-1 Ag and TAT was significantly higher than that of plasma(p<0..001). The severity of pleural inflammation did not correlated with pleural D-dimer, PAI-1 Ag, TAT and their plasma levels. But the level of pleural TAT correlated with pleural WBC and lymphocyte count. Conclusion : We found that the severity of pleural inflammations did not correlated with pleural D-dimer, PAI-1 Ag, TAT and the possibility of local production of PAI-1 antigen is present.

  • In this study, Cyperus rotundus (C. rotundus) was fractionated into ethyl acetate to identify α-cyperone, a representative indicator, and its ethyl acetate fraction were evaluated to confirm the possibilityas a functional cosmetic ingredient. As a result of HPLC analysis, it was confirmed that the content of α-cyperone was 5.243%. In order to verify the inflammatory relief effect of the ethyl acetate fraction from C. rotundus (EAFC) and α-cyperone, it was confirmed that nitric oxide (NO) production inhibitory ability in RAW 264.7 macrophages induced an inflammatory reaction with lipopolysaccharide (LPS). Real-time qPCR analysis confirmed inhibition of mRNA expression level of inflammatory factors, IL-1β, IL-6, TNF-α, COX-2 and iNOS. As a results of conducting a clinical study using a simple cosmetic formulation containing EAFC, it was confirmed that the skin irritation stimulated by sodium lauryl sulfate (SLS) was calming and relieving itching. Through these results, it is believed that the C. rotundus can be used as a natural cosmetic ingredient that has the effect of inhibiting inflammation and relieving itching.

  • The antioxidant and anti-neuroinflammatory activities of water, 30, 70, and 100% ethanol extracts of leaves of three different species of bamboo (Phyllostachys nigra, P. bambusoides, and Sasa borealis) were investigated. The levels of total polyphenol and flavonoid were measured, and antioxidant activity was evaluated using various antioxidant assays (DPPH, ABTS, and FRAP). Lipopolysaccharide (LPS)-induced BV2 microglial cell activation was used to evaluate the anti-neuroinflammatory properties of the bamboo leaf extracts. Treatment with both aqueous and ethanolic extracts showed no cytotoxicity in BV-2 microglial cells. Pre-treatment of BV-2 cells with bamboo leaf extracts significantly inhibited LPS-induced excessive production of nitric oxide in a dose-dependent manner. Moreover, phytochemical analysis based on the extraction solvent showed that caffeic acid, p-coumaric acid, and tricin are the principal constituents of all three bamboo leaf extracts. Therefore, our findings suggest that bamboo leaf extract contains potent antioxidants and anti-neuroinflammatory compounds that can be used as potential therapeutic agents for the treat neuroinflammatory diseases.
