  • In this study, we investigated anti-oxidative and anti-inflammatory efficacy, and identified their constituents from Brassica napus L. (Korean name: Yuchae) whole plant. Upon the anti-oxidative activities screening, the ethanol extract exhibited potent DPPH and ABTS+ radical scavenging activities. On the anti-inflammation studies using LPS-induced RAW264.7 cells, the extract inhibited the production of NO and pro-inflammatory cytokines (TNF-α, IL-1β, IL-6) effectively. To identify major constituents of B. napus extract, further purification was performed and led to isolation of two compounds; isorhamnetin 3,7-O-diglucoside(1) and isorhamnetin 3-O-glucoside(2). Quantitative analysis by high pressure liquid chromatography (HPLC) determined the flavonoid 1 as the major constituent. Isolated compounds showed DPPH radical scavenging effects and decreased NO levels without causing cell toxicities. These results indicate that the extract of Yuchae, a rich plant resource in Jeju Island, could be potentially applicable as an anti-oxidative and/or anti-inflammatory ingredients.

  • Background: Although IL-12 has been widely accepted to playa central role in the control of pathogen infection, the use of recombinant IL-12 (rIL-12) as a vaccine adjuvant has been known to be ineffective because of its rapid clearance in the body. Methods: To investigate the effect of sustained release of IL-12 in vivo in the peptide and protein vaccination models, rIL-12 was encapsulated into poly ($A_{DL}$-lactic-co-glycolic acid) (PLGA). Results: We found that codelivery of IL-12-encapsulated microspheres (IL-12EM) could dramatically increase not only antibody responses, but also antigen-specific $CD4^+\;and\;CD8^+$ T cell responses. Enhanced immune responses were shown to be correlated with protective immunity against influenza and respiratory syncytial virus (RSV) virus challenge. Interestingly, the enhancement of $CD8^+$ T cell response was not detectable when $CD4^+$ T cell knockout mice were subjected to vaccination, indicating that the enhancement of the $CD8^+$ T cell response by IL-12EM is dependent on $CD4^+$ T cell "help". Conclusion: Thus, IL-12EM could be applied as an adjuvant of protein and peptide vaccines to enhance protective immunity against virus infection.

  • This study aimed to discover functional materials derived from resources, which can improve the troublesome symptoms of a bronchus by improving bronchial hyperresponsiveness as air pollution in Korea caused by fine dust and yellow dust is getting worse. Of natural resources grown naturally in Korea, Chrysanthemum morifolium(CM), and Scutellaria baicalensis(SB) have been used as a safe raw material for drinking or medicine for a long time, and it has been found that a combination of CS73 can improve bronchial health function in experimental animal models. Analysis of serum of animal models with asthma induced by ovalbumin (chicken egg albumin) and analysis of cytokine production in BALF (Bronchoalveolar lavage fluid) showed that inflammatory indices IL-1β, IL-4, IL-5, IL-6, IL-10, IL-13, IL-17A, IL-17F, and IL-17E were significantly reduced and that respective production of IL-2 and IFN-γ was significantly increased in the group taking extracts from CS73 when compared with the control group. These results suggested that the combination of CS73 could be used as a natural treatment for asthma. In addition, in the animal models that the combination of CS73 significantly decreased the respective production of IgE, histamine and TSLP when compared with the control group. In experimental models, the ratio of Chrysanthemum morifolium to Scutellaria baicalensis of 7 : 3 had more excellent effect than other combined experimental groups, which suggests that the above combination can be developed as a natural treatment for asthma and is valuable as a pharmaceutical composition with an effect of improving bronchial health, capable of contributing to the public health threatened by fine dust.

  • To evaluate antiallergic effect of Brassica rapa Metzg (BR, Family Cruciferae), which is widely used as a food source, its anti-asthmic effect was investigated. BR reduced IgE level in the blood of ovalbumin (OVA)-induced asthmic mice. BR also inhibited IgE and ploinflammatory cytokine IL-6 productions in trachea of OVA-induced mice, but did not inhibit IL-4 production. BR did not inhibit mRNA expression of proinflammatory cytokines IL-6 and IL-4 in IgE-induced RBL-2H3 cells. BR and its isolated components 10-undecenoic acid 2-methoxy methyl ester and galactosyl diglyceride potently inhibited the NO production of RAW264.7cells induced by lipopolysaccharide. These findings suggest that the anti-asthmic effect of BR may be due to the inhibition of the biosynthesis of proinflarnmatory cytokine IL-6 in macrophage and BR can improve IgE-induced allergic disease asthma.

  • 직경이 10 ㎛ 미만의 미세먼지 입자(particulate matter 10, PM10)는 한국을 비롯한 동아시아 지역에서 해로운 대기오염의 주요한 원인 중 하나로 최근 주목받고 있으며, 호흡기와 피부에 유해한 영향을 미치는 주범이 되고 있다. FD는 대식세포에서 활성산소 종(ROS)의 생성과 염증반응을 과도하게 촉진시켜 세포 손상과 더불어 세포 사멸을 유도한다. 장미속의 낙엽관목인 해당화(Rosa rugosa)는 다양한 질병을 치료하는 목적으로 예부터 동아시아 지역에서 민간요법 치료제로써 사용되었다. 본 연구에서는 PM10으로 유도된 RAW 264.7 대식세포에서의 염증반응을 억제하는 해당화 각 기관별 추출물의 항염증 효과를 탐색하고자 한다. 미세먼지 입자가 처리되지 않은 RAW 264.7 대식세포와 비교했을 때, PM10을 100 ㎍/ml의 농도로 처리했을 경우 lipopolysaccharide 처리와 유사하게 nitric oxide (NO) 생성을 눈에 띄게 증가시켰다. 또한 100 ㎍/ml의 해당화 줄기 추출물은 미세먼지 입자 단독 처리군에 비해 NO 생성을 45% 이상 감소시켰고, PM10에 의해 유도된 interleukin(IL)-1β, IL-6, inducible nitric oxide synthase, and cyclooxygenase-2의 발현을 유의하게 감소시켰다. 이러한 결과는 해당화 줄기 추출물의 항염증 효과가 PM10으로 자극된 RAW 264.7 세포에서 염증 유발 매개체의 억제에 의해 매개됨을 나타내며, 해당화 줄기가 유해한 공기 중 미세먼지 입자에 의해 유발되는 염증반응에 대한 보호 효과가 있는 천연 자원으로서 가치가 있음을 시사한다.

  • Although the roots of Heracleum moellendorffii (HM-R) have been long treated for inflammatory human diseases, scientific evidence for the anti-inflammatory activity of HM-R is not sufficient. In this study, we investigated anti-inflammatory activity and mechanism of action of HM-R in LPS-stimulated RAW264.7 cells. HM-R blocked LPS-induced NO and PGE2 production, but not HM-L. HM-R inhibited LPS-induced overexpression of iNOS, COX-2, $IL-1{\beta}$ and IL-6 in RAW264.7 cells. HM-R inhibited LPS-induced $NF-{\kappa}B$ signaling activation through blocking $I{\kappa}B-{\alpha}$ degradation and p65 nuclear accumulation. In addition, HM-R inhibited MAPK signaling activation by attenuating the phosphorylation of ERK1/2, p38 and JNK. Furthermore, HM-R inhibited attenuated LPS-mediated overexpression of the osteoclast-specific factors such as NFATc1, cathepsin K, MCP-1 and TRAP. These results indicate that HM-R may exert anti-inflammatory activity by inhibiting $NF-{\kappa}B$ and MAPK signaling activation. From these findings, HM-R has potential to be a candidate for the development of chemopreventive or therapeutic agents for the inflammation and inflammatory diseases.

  • 체내 면역 증강정을 관찰하기 위하여 체내 임파구의 활성 및 증가 여부를 3개월간 의뢰한 물질인 Immu-Forte EX, Immu-Forte 된장고추장, Immu-Forte A, Immu-Forte를 투여한 후, flowcyometry 및 sandwitch ELISA를 이용하여 측정하였다. 본 실험의 실험 기간 중에 동물의 질병이나 감염에 의한 면역학적인 변화가 있었는지를 확인하기 위하여 혈액학적인 검사를 실시하였으며, 혈액학적인 검사에서 Alkaline phosphatase, T protein, Albumin, Creatine, ALT, AST, Total bilirubin, Potasium을 검사해 본 결과 대조군과 비교 했을때 투여군 전군에서 정상적인 범위내 수치를 나타내는 것으로 나타났다. 이러한 결과로부터 본 실험에서 나온 결과는 질병이나 감염에 의한 것이 아닌 생체내에서의 면역성 증강에 의한 것으로 판단할수 있는 근거를 제공한다고 판단되어진다. 한편, 3개월간 장기 투여시 Immu-Forte EX, Immu-Forte 된장고추장, Immu-Forte A과 Immu-Forte 의 모든 물질은 전반적으로 면역 세포와 사이토카인의 수치를 유의적으로 증가시켰다 그러나, 3개월간 Immu-Forte EX를 투여 후 혈중콜레스테롤 수치를 검사해 본 결과 대조군$(118\pm24.4 mg/dL)$과 비교하였을때, 고용량$(126\pm7.7 mg/dL)$, 중간용량$(121\pm8.4 mg/dL)$, 저용량$(109\pm24.Smg/dL)$으로서 통계학적인 유의적 감소로는 보이지 않는다. 각각의 물질의 면역학적인 변화양상을 살펴보면 물질 동암 EX는 중간 농도군에서는 CD4 T 림파구, CD8 림파구, 대식세포, IL-12, IFN-r가 대조군에 비해서 유의적으로 증가했으며 떠농도에서는 전체 T 임파구, 전체 B 임파구, CD4 T 임파구, 대식세포, IL-2, IL4, IL-12가 대조군에 비해서 유의적으로 증가했다. 물질 Immu-Forte 된장고추장에서는 고농도에서는 CD4 T 임파구, IL-2, IL-4, IL-12가 유의적으로 증가했으며, 중간농도에서는 CD4 임파구, 대식세포, IL-2,IL-4,IL-12 가 유의적으로 증가했고, 저농도에서는 전체 T 임파구, CD4 T 임파구, IL-2, IL-4, IL-12가 유의적으로 증가했다. 물질 Immu-Forte A의 경우 고농도에서 대식세포,자연살해세포, IL-12가 중간농도에서는 전체 T임파구, CD4 T임파구, 대식세포, 자연살해세포, IL-2, IL-4, IL-12가 저농도에서는 자연살해세포가 유의적으로 증가했다. 물질 Immune-Forte f의 경우 고농도에서 전체 B 임파구, IL-4, IL-12가 중간농도에서 전체 T임파구, 전체 B임파구, CD4 T임파구, CD8 T 임파구, 대식세포, IL-2, IL-4, IL-12, IFN-r가 저농도에서는 자연살해세포, IL-12가 유의적으로 증가하였다. 이상과 같이 각각의 물질은 전반적으로 면역증강 효과가 있는 것으로 나타났으며 그 면역증강을 유도하는 세포나 사이토카인은 서로 정확히 일치하지 않는 것으로 보아 각각의 물질이 다른 기전을 통해서 면역증강을 유도하는 것으로 생각된다.

  • 문주란(Crinum asiaticum Linne var. japonicum)은 한국, 말레이지아 등 동남아시아 지역에서 관절통, 해열, 궤양 치료, 국부의 소염 및 해열 등의 목적에 민간요법 등으로 오래 전부터 사용되어 오고 있다. 본 연구에서는 이러한 문주란의 화장료 조성물로서의 가능성을 확인하기 위하여 iNOS (inducible nitric oxide synthase) 억제 그리고 PGE2, IL-6, and IL-8 방출 억제에 의한 항염 효능을 측정하였다. pH를 3.5로 조절하고 95% ethanol을 사용하여 추출한 후, HPLC 실험으로 문주란의 주성분이 면역조절물질로 잘 알려진 lycorine이며 대략 1% 정도 함유한 것을 확인하였고 그 함량은 문주란의 추출 부위 및 추출방법에 따라 달랐다. 리포다당(lipopolysaccharide, LPS)에 의해 활성화된 생쥐 대식세포(RAW 264.7 cells)에서 생성되는 NO 형성의 억제능을 측정한 항염실험에서, 문주란 에탄을 추출물은 투여량에 비례하는 저해능을 가지고 있음을 확인할 수 있었다($IC_{50} = 83.5 {\mu}g/mL$). 또한 RT-PCR법을 이용하여 문주란 에탄을 추출물이 iNOS 유전자 발현도 억제함을 확인하였다. 또한, 문주란 추출물은 전혀 세포독성을 보이지 않았으며 오히려 LPS에 대하여 세포증식효과를 나타내었다(세포생존율 약 $10{\sim}60%$ 증가). 인간의 섬유아세포에서 과산화수소에 의해 활성화된 PGE2, IL-6 및 IL-8 방출 억제효능 측정 실험에서는 0.05%와 1% 농도 이상에서 (PGE2와 IL-6의 분비가) 거의 완전히 억제됨을 확인할 수 있었고, 나아가서 IL-8의 경우는 모든 실험농도 범위에서 완전히 억제되었다(>0.0025%). 이러한 결과로부터 문주란의 추출물이 충분한 항염 효과를 가지고 있음을 확인할 수 있었다.

  • In order to evaluate the antiallergic effects of Kamiyukgunja-tang (KYGJT), studies were done. We measured the cytotoxic activity for lung fibroblast cell, cytokines transcript expression, production of INF-γ, IL-10, IL-4, GM-CSF, IL-1 β, TNF-α. IL-5 proliferation of B cell in anti-CD40mAb plus r1L-4 stimulated murine splenic B cells. The results were obtained as follows : 1. KYGJT was not showed cytotoxicity in the fibroblast lung cell. 2. KYGJT increased the gene synthesis of INF-γ, IL-10, GM-CSF(m-RNA). 3. KYGJT decreased the gene synthesis of IL-1β, IL-4, TNF-α, IL-5(m-RNA). 4. KYGJT decreased the appearance of TNF-α significantly. 5. KYGJT decreased the appearance of IgE significantly. 6. KYGJT decreased the proliferation of B cell significantly. 7. KYGJT decreased the appearance of Histamin Release Production significantly. The facts above prove that KYGJT is effective against the allergy. Thus. I think that we should study on this continuously

  • Objectives: The object of this study was to observe the in vitro anti-bacterial and anti-inflammatory effects of six single aqueous herbal extracts-Quisqualis Fructus (QuF), Meliae Cortex (MeC), Arecae Semen (ArS), Crassirhizomae Rhizoma (CrR), Ulmi Pasta Semen(UlS), Torreyae Semen(ToS)- against Staphylococcus aureus (S. aureus) and Lipopolysaccharide(LPS)-activated Raw 264.7 cells. Methods: Anti-bacterial activities against S. aureus of aqueous extracts of QuF, MeC, ArS, CrR, UlS and ToS were detected using standard agar microdilution methods. In addition, the effects on the cell viability, prostaglandin $E_2$ ($PGE_2$), nitric oxide (NO), tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), interleukin (IL)-$1{\beta}$ and IL-6 productions of LPS activated Raw 264.7 cells were detected. The anti-bacterial and anti-inflammatory effects were respectively compared with lincomycin and piroxicam. Results: Minimal Inhibition Concentration (MIC) of aqueous extracts of QuF, MeC, ArS, CrR, UlS and ToS against S. aureus was respectively detected $5.625{\pm}4.075$ (3.125~12.500), $0.332{\pm}0.273$ (0.098~0.782), $1.094{\pm}0.428$ (0.782~1.563), $2.969{\pm}2.096$ (0.782~6.250), $9.375{\pm}4.419$ (3.125~12.500)>25 mg/ml. MIC of lincomycin was detected as $0.469{\pm}0.297$ (0.195~0.782) ${\mu}g/ml$ at same conditions. In addition, $ED_{50}$ against LPS-induced cell viabilities and cytokine releases of QuF, MeC, ArS, CrR, UlS and ToS was as follows - Cell viability: 66.370, 2.908, 1.747, 259.553, 18.150 and 34.160 mg/ml; NO production: 389.486, 0.294, 0.138, 523.060, 45.363 and 49.327 mg/ml; $PGE_2$ production: 114.271, 0.223, 0.046, 243.078, 8.829 and 28.947 mg/ml; TNF-${\alpha}$ production: 406.288, 0.343, 0.123, 9404.227, 125.406 and 140.775 mg/ml; IL-$1{\beta}$ production: 117.178, 0.135, 0.019, 237.451, 7.923 and 19.418 mg/ml; IL-6 production: 31.261, 0.105, 0.055, 128.434, 2.290 and 3.745 mg/ml. ED50 of piroxicam against LPS-induced cell viabilities, NO, $PGE_2$, TNF-${\alpha}$, IL-$1{\beta}$ and IL-6 were detected as 35.179, 6.552, 1.162, 7.273, 7.101 and $5.044{\mu}g/ml$, respectively at same conditions. Conclusions: All six single aqueous herbal extracts showed anti-bacterial effects against S. aureus, in the order of MeC, ArS, CrR, QuF and UlS aqueous extracts except for ToS; they did not showed any anti-bacterial effects (MIC>25 mg/ml). They also showed anti-inflammatory effects against LPS-activated Raw 264.7 cells in the order of ArS, MeC, UlS, ToS, QuF and CrR aqueous extracts. It means that the ArS and MeC will be showed favorable potent anti-bacterial and related anti-inflammatory effects.
