  • The purpose of this study was to investigate the anti-obesity and anti-inflammation effect of the cheonggukjang (a soybean paste fermented for only a few days) in diet induced obesity mice. Weight gain was significantly decreased in the mice fed cheonggukjang compared High Fat Diets (HFD). The HFD plus cheonggukjang (CGJ) were also effective in improving the lipid metabolism. The levels of plasma triglyceride, cholesterol, ALT, AST, leptin, glucose, and insulin were significantly lower in CGJ than HFD group (p<0.05). The adiponectin level of CGJ group was significantly increased compared to the HFD group (p<0.05). In the CGJ group, the mRNA expression of adipogenic genes in the liver and adipose tissues, which are transcription factors crucial for adipogenesis, were significantly suppressed (p<0.05). The number of $CD11b^+F4/80^+$ T cells, $Gr-1^{int}CD11b^{high}$ cells, and $Gr-1^{int}CD11b^{high}$ cells were significantly higher in HFD group than CGJ group (p<0.05). The size of adipocyte was significantly reduced in CGJ group compared to HFD group. In addition, the contents of liver lipid droplets were significantly downregulated in the CGJ mice than HFD mice (p<0.05). Collectively, these data suggest the novel function of cheonggukjang in modulating adipogenesis through an immune function-alteration involving downregulation of adipogenic transcription factors and macrophage activation.

  • Dichloromethane, ethanol, and boiling water extracts of the green seaweed Codium fragile, used as an herbal medicine and known as an invasive species over the world, were examined for anti-inflammatory, antipyretic, and analgesic activities in mice. The dichloromethane and ethanol extracts inhibited inflammatory symptoms of mouse ear edema and erythema by 74% or higher. The extracts also demonstrated inhibition of pyrexia, similar to that of acetyl salicylic acid. Eicosapentaenoic acid was isolated from the seaweed as the main active anti-inflammatory compound. These findings are consistent with various claims that the seaweed can be used as remedies for inflammation-related symptoms.

  • A direct complement fixation test supplemented with procomplementary porcine serum was studied using anticomplementary human, rabbit and bovine serum against Mycobacterium tuberculosis. Procomplementary activity of porcine serum varied with porcine individual and affected by anticomplementary antiserum. The procomplementary titre of porcine serum against rabbit, human and bovine serum ranged from 1:5 to 1:40. By means of complement fixation test supplemented by porcine serum, the specific complement-fixing antibody to both tuberculopolysaccharide and/or tuberculoprotein antigen was readily differentiated from the anticomplementary antibody titre.

  • 목적 : 진피(Citus Unshiu, CU)는 실험적으로 항산화, 항알러지, 항종양 효과 등이 있다고 보고되고 있다. 본 연구에서는 비만세포에서 PMA와 A23187에 의하여 유도된 싸이토카인의 증가에 대한 진피 추출물의 억제 효과와 그 기전을 알아보고자 한다. 방법 : PMA+A23187에 의한 싸이토카인 생성에 대한 진피 추출물의 억제효과 기전을 조사하기 위하여 진피를 처리한 후 $IL-1{\beta}$, IL-8, $TNF-{\alpha}$의 생산 및 혈관내피성장인자 (VEGF), 과립구 대식구 군집 자극 인자 (GM-CSF), 저산소 유도 인자(HIF-1)의 발현을 조사하였다. 결과 : 실험에서 PMA와 A23187을 처리한 경우 대조군에 비하여 $IL-1{\beta}$, IL-8, $TNF-{\alpha}$의 생산을 유의하게 증가시켰으나 진피 추출물을 처리한 군에서는 유의하게 억제되었다. 특히 $IL-1{\beta}$의 생성은 $103.7{\pm}5%$, IL-8 생성은 $34.6{\pm}7%$, $TNF-{\alpha}$의 생성은 $85.9{\pm}4.5%$ 억제되었다. (P<0.05). 또한 진피 추출물은 PMA와 A23187에 의하여 증가한 VEGF, GM-CSF, $HIF-1{\alpha}$의 발현 증가를 억제하였다 (약 90.9%의 VEGF, 61.6%의 GM-CSF). 결론 : 이러한 결과는 진피가 염증반응에 대한 HIF-1의 억제자로 작용할 수 있으면, 진피가 비만세포 매개성 염증 질환 치료제의 후보 물질이 될 것으로 사료된다.

  • 호흡기 바이러스 감염은 모든 연령층의 천식에 상당한 영향을 미치는 데 영아에서 RSV는 천명을 야기하고 대부분 일시적이나 재발성 일수도 있다. 어릴 때 바이러스 감염은 면역체계 형성에 영향를 미쳐 알러지와 천식의 위험을 완하할 수있다고 한다. 또한 소아와 성인 천식에서 RV같은 감기 바이러스는 천식의 급성 증상을 유발한다. 호흡기 바이러스 감염에 대한 면역반응이, 기관지로 부터 바이러스 제거 기능외에 기도수축과 호흡기 증상에 관여한다고 한다. 이러한 변화가 일어나는 기전은 호흡기 바이러스가 proinflammatory 사이토카인과 매개체 생성을 유도하는 능력과 연관성이 있는 것 같고 이들이 상하기도 호흡기 증상 및 기도반응 변화에 관여하는 것으로 생각된다. 호흡기 바이러스 감염에 대한 면역반응을 요약하면 바이러스 감염으로 상피세포, 내피세포, 과립백혈구가 활성화되며, 상피세포는 사이토카인, 키모카인, 매개체들을 분비하여 항 면역 반응를 주도하다. 이와 같은 상피세포와 다른 기관지 세포들의 조기 활성화로 내피 세포에 유착분자 표현을 증가시켜 백혈구 동원 증가 및 혈관 투과성을 증가시켜 부종과 분비물을 증가시킨다. 바이러스 또는 바이러스 유발 사이토카인에 의해 활성화된 과립 백혈구, 대식세포, T세포들도 기도염증 증가, 기도폐쇄를 야기하고 기도반응을 증가시킨다. 세포독성 임파구에 의한 바이러스 감염세포의 분해, TGF-$\beta$ IL-10 같은 사이토카인에 의해 부분적으로 염증억제, 기도 remoldeling에 의한 기도구조의 재생등이 바이러스 감염후 기관지 기능의 지속적 변화를 결정한다. 끝으로 천식환자에서 RV 감염의 병인에 관한 기본적 문제는 RV감염이 정상인에서는 경한 증상을 나타내는 데 천식환자에서는 왜 심한 임상증상을 나타내는지 아직 완전히 밝혀지지 않았다. 항 바이러스에 대한 면역반응이 천식환자에서 손상되었는지 또는 천식환자에서 RV감염에 의한 중증의 임상증상은 어떤 다른 세포가 관여하는지? 이들에 대한 답은 기도염증이 천식에서 어떻게 조절되는지 또한 바이러스 감염에 의한 악화된 증상을 어떻게 치료할 것인가에 대한 방향을 제시해줄 것이다.

  • The principal objective of this study was to compare and analyze the qualitative properties of MLT (mulberry leaf tea) and FMLT (fermented mulberry leaf tea) on the basis of the anti-cancer and anti-allergy activities of various extracts. The inhibitory effect against S-180 solid cancer in vivo were measured as 16.67% for FMLT and 17.78% for MLT. When the anti-allergy effects of the extracts of MLT and FMLT were evaluated, the hot water extract was shown to block histamine secretion more effectively than the ethanol extract for both groups. Furthermore, when the levels of the inflammatory cytokine of HMC-1 were measured, the ethanol extract was found to inhibit the inflammatory cytokine more effectively than the hot water extract, and the FMLT group was more effective than the MLT group.

  • Traditionally, the larvae of Allomyrina dichotoma (AD), a species of the rhinoceros beetle, have been widely used for their antidiabetic, antihepatofibrotic, antineoplastic, and antiobesity effects. The United Nations' Food and Agriculture Organization has reported on the possibility of using edible insects in human dietary supplements in the future. However, despite the growing interest in insect-based bio-active products, the biological activities of these products have rarely been studied. Previously, we reported that AD larvae inhibit the in vitro differentiation of adipocytes via transcription factor downregulation. In this study, our objective was to evaluate the effects of a hot-water extract of AD larvae on allergy and inflammation. To investigate the inhibitory effect of the extract on allergic reactions, we measured the levels of ${\beta}-hexosaminidase$, tumor necrosis $factor-{\alpha}$ ($TNF-{\alpha}$), interleukin-4 (IL-4), and cyclooxygenase-2 (COX-2) after activation of RBL-2H3 cells using Compound 48/80. In addition, the inhibitory effect of the extract on inflammation was determined using Raw 264.7 cells after lipopolysaccharide (LPS) stimulation. The extract significantly inhibited the ${\beta}-hexosaminidase$, $TNF-{\alpha}$, IL-4, and COX-2 levels in RBL-2H3 cells. Furthermore, it effectively inhibited the inflammatory cytokine IL-6, nitric oxide, and inducible nitric oxide synthase expression in LPS-stimulated Raw 264.7 cells. These results suggest that AD larval extract can be potentially developed as an antiallergic and anti-inflammatory therapeutic agent.

  • Essential oils have been used extensively in pharmacy, medicine, food, beverages, cosmetics, perfumery and aromatherapy. Although anti-bacteria, anti-virus, alleviation of fever operations and an anti-inflammatory properties have been reported, action mechanisms have not been fully discovered. In the present study, anti-inflammatory activities of thirty three essential oils have been evaluated in lipopolysaccharide (LPS)-treated macrophage RAW 264.7 cells by the evaluation of nitric oxide (NO) generation since NO generation is implicated in causal factor of inflammation. Among the tested 33 essential oil, Lemongrass oil showed the most inhibitory effect on LPS-induced NO generation in a dose dependent manner ($IC_{50}$ : $22 {\mu}g/mL$). In further study, it was found that Lemongrass oil inhibited the expression of inducible nitric oxide synthase. These results suggest that Lemongrass oil may be useful for improvements of the inflammatory disease such as pimple acne skin.

  • The moringa (Moringa oleifera Lam.) plant is used both as food and an anti-allergic agent. In this study, we investigated skin protection effects of methanol extracts from the root, seed, fruit, and leaves of moringa in HaCaT keratinocyte cells. To investigate the pharmacological potential of various moringa extracts on TNF-${\alpha}$-induced collagen degradation in HaCaT cells, we measured the activity of matrix metallopeptidase-9,2 (MMP-9,2) by zymography analysis. Our results showed that all the moringa extracts inhibit the TNF-${\alpha}$-induced enzyme activity of MMP-9. In particular, moringa root extracts significantly suppressed MMP-9 and MMP-2 in a dose-dependent manner. Next, to investigate the anti-inflammation effect of the moringa extracts, we examined cyclooxygenase-2 (COX-2), inducible nitric oxide synthase (iNOS), and interleukin-6 (IL-6) expression of the extracts. The results showed that both the root extracts and the seed extracts decreased the TNF-${\alpha}$-induced expression of COX-2. In addition, the root and leaf extracts reduced the expression of IL-6. However, none of the moringa extracts affected the expression of iNOS. The results suggest that moringa root extracts down-regulate MMP-9, COX-2, and IL-6 and that the root extracts offer superior skin protection effects compared with other extracts of moringa in HaCaT cells.

  • This study aimed to evaluate the anti-adipogenic and anti-inflammation effects of extract from Maclura tricuspidata twig fermented with Ganoderma lucidum mycelium (EMFG) in 3T3-L1 preadipocytes. 3T3-L1 adipocytes were treated with 100, 200, 300 ㎍/mL of EMFG. The result showed that EMFG dose-dependently inhibited the accumulation of intracellular lipid content in differentiated 3T3-L1 adipocytes and enhanced increase of adiponectin release and inhibition of leptin release. EMFG treatment reduced expression of adipogenic transcriptional factor such as peroxisome proliferator-activated receptor γ (PPARγ), CCAAT-enhancer-binding protein α (C/EBPα). EMFG also decreased production of lipopolysaccharide (LPS)-induced inflammatory cytokine [tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and monocyte chemoattractant protein-1 (MCP-1)] and the protein expression of cyclooxygenase-2 (COX-2) and inducible NOS (iNOS) in differentiated 3T3-L1 adipocytes. The study demonstrated that EMFG inhibited adipogenesis and inflammation in a dose-dependent manner. These findings suggest that EMFG may have potential as an anti-obesity and anti-metabolic disease agent that works by inhibiting adipogenesis and inflammation.
