  • Background: Ginsenoside Rg3, isolated from Panax ginseng, has anti-inflammatory and anti-tumor activities. It is known to reduce inflammation in acute lung injury in mice, and to reduce the expression of inflammatory cytokines and COX-2 in human asthmatic airway epithelium. In this study, we attempted to determine whether ginsenoside Rg3 inhibits airway inflammation, oxidative stress, and airway hyperresponsiveness (AHR) in the lungs of asthmatic mice. We also investigated its effects on oxidative stress and the inflammatory response in tracheal epithelial cells. Methods: Asthma symptoms were induced in female BALB/c mice sensitized with ovalbumin (OVA). Mice were divided into five groups: normal controls, OVA-induced asthmatic controls, and asthmatic mice treated with ginsenoside Rg3 or prednisolone by intraperitoneal injection. Inflammatory BEAS-2B cells (human tracheal epithelial cells) treated with ginsenoside Rg3 to investigate its effects on inflammatory cytokines and oxidative responses. Results: Ginsenoside Rg3 treatment significantly reduced eosinophil infiltration, oxidative responses, airway inflammation, and AHR in the lungs of asthmatic mice. Ginsenoside Rg3 reduced Th2 cytokine and chemokine levels in bronchoalveolar lavage fluids and lung. Inflammatory BEAS-2B cells treated with ginsenoside Rg3 reduced the eotaxin and pro-inflammatory cytokine expressions, and monocyte adherence to BEAS-2B cells was significantly reduced as a result of decreased ICAM-1 expression. Furthermore, ginsenoside Rg3 reduced the expression of reactive oxygen species in inflammatory BEAS-2B cells. Conclusion: Ginsenoside Rg3 is a potential immunomodulator that can ameliorate pathological features of asthma by decreasing oxidative stress and inflammation

  • 본 연구에서는 영지버섯 균사체 발효 꾸지뽕 잔가지 추출물의 지방세포 분화 억제 및 염증 억제 효과를 확인하고자 하였다. 세포독성을 확인한 결과, 최대 1,000 ㎍/mL 농도까지 세포에 처리하여도 세포 생존율이 감소하지 않음을 확인되었다. 분화과정 동안 발효 꾸지뽕 잔가지 추출물을 처리하였을 때, 세포 내 지방 축적이 감소되었다. 분화과정에 관여하는 대표적인 adipokine인 leptin과 adiponectin의 생성량을 확인한 결과, 발효 꾸지뽕나무 잔가지 추출물에 의해 adiponectin의 생성 증가와 leptin의 생성 감소를 확인하였다. 지방세포 분화 관련 유전자의 발현은 분화 유도인자만 처리한 군에 비해 발효 꾸지뽕나무 잔가지 추출물이 함께 처리된 군에서 추출물의 농도가 높아질수록 지방분화 전사인자인 PPARγ와 C/EBPα의 발현량이 감소하는 것을 확인하였다. 분화된 3T3-L1 세포에서 LPS에 의해 분비되는 염증성 사이토카인(TNF-α, IL-6, MCP-1)의 생성량 변화를 측정한 결과, LPS 처리로 증가된 염증성 사이토카인의 생성을 억제하였으며 염증 관련 유전자인 iNOS, COX-2의 발현도 감소되었다. 또한, 발효 꾸지뽕나무 잔가지 추출물과 발효되지 않은 꾸지뽕나무 잔가지 추출물을 비교하였을 때, 발효 꾸지뽕나무 잔가지 추출물이 지방세포 분화 및 염증 억제 효과에서 더 높은 활성을 보였으며, 이들 결과를 종합적으로 볼 때, 영지버섯 균사체를 이용한 발효가 꾸지뽕나무 잔가지의 활성 증가에 기여하는 것으로 보인다. 따라서 발효 꾸지뽕나무 잔가지 추출물은 항비만, 항염증 소재로서 비만뿐만 아니라 대사성 질환 개선을 위한 기능성 소재로서 활용이 가능할 것으로 판단되며, 향후 발효 꾸지뽕나무 추출물의 명확한 항비만, 항염증 효능을 확인하기 위해서는 유용 물질 분리 및 작용기전 등 추가적인 연구가 필요할 것으로 판단된다.

  • 비만은 감염원 없이 진행되는 낮은 수준의 만성적인 전신성 염증상태로 간주되며, 만성대사질환의 원인이 된다. 본 연구에서는 미나리를 발효하여 만든 식초가 3T3-L1 지방전구세포의 분화 및 RAW 264.7 세포에서의 항염증 효과에 미치는 영향을 확인하였다. MDI (IBMX, dexamethasone, insulin)에 의해 분화가 유발된 3T3-L1 지방전구세포에 대한 미나리 식초의 분화 억제능을 Oil-red-O staining을 통해 확인하였으며, western blot법을 통해 지방세포 형성 시 중요한 전사인자인 peroxisome proliferator-activated receptor-${\gamma}$ (PPAR-${\gamma}$)와 CCAAT-enhancer-binding protein ${\alpha}$ ($C/EBP{\alpha}$)의 발현을 감소시키는 것으로 나타났다. 또한, 미나리 식초가 lipopolysaccharide (LPS)에 의해 염증이 유발 된 RAW 264.7 세포의 nitric oxide (NO) 생성을 억제시켰으며, inducible NO synthase (iNOS)와 cyclooxygenase-2 (COX-2)의 단백질 발현을 감소시키는 것을 확인하였다. 이러한 결과들을 통해 미나리 발효 식초는 지방세포 분화와 염증 억제 효과를 가지고 있음을 확인하였다. 따라서 미나리 발효 식초는 대사성 질환을 예방할 수 있는 천연물 소재로 이용 가능할 것으로 생각된다.

  • Objectives ; This study was to investigate the anti-cancer effects of herbal acupuncture with distilled fresh ginseng. The herbal acupuncture was injected to Chung-wan($C.V_{12}$) and Wisu($BL_{21}$) of mice that were subjected to Sarcoma-180 adbominal cancer cell and A549 human epithelial lung cancer cells in vitro. Methods : Anti-cancer effects of distilled fresh ginseng herbal acupuncture were tested by measruing Cox, Bcl-2, and Bax by using RT-PCR in A549 human epithelial lung cancer cells in vitro. And four weeks old Balb/c line male mice weighing around $20\;{\pm}\;3g$ were used to measure survival rate and anti-cancer effect to outputs of interleukin-2 and interleukin-4 using flow cytometry, possibility of mRNA menifestation using RT-PCR, and Cox mRNA. The results are as follows. Results : 1. In measuring mRNA menifestation in Cox, Bcl-2, and Bax by using RT-PCR in A549 human epithelial lung cancer cells in vitro, the result showed that fresh ginseng decreased Cox-2 which is directly involved in Inflammation process. 2. Survival rate was measured in an anti-cancer effect experiment against Sarcoma-180 abdorminal cancer. Median survival time of controlled group was 27 days, of experiment group I was 21 days, and of experiment group II was 27 days. Therefore, experiment group I showed -22.2% increase in survival rate and experiment group II showed no difference compare to controlled group. 3. There was no difference between condition group and controlled and experiment group in measuring outputs of interleukin-2 and interleukin 4 by using flow cytometry 4. In measuring outputs of interleukin-2 by using ELISA, there was no significant difference between condition group and controlled group and there was decrease in experiment group II compared to conditioned and controlled group. 5. In measuring cytokine mRNA menifestation by using RT-PCR, experiment group I showed increase of mRNA menifestation in interleukin-2,4 and $interferon-{\gamma}$ and experiment group II showed no significant difference in $interferon-{\gamma}$. Conclusion : According to the results, fresh ginseng herbal-acupuncture took a little effects in cancer. In using distilled fresh ginseng herbal acupuncture has effect on Cox-2 decrease. However, the difference in concentration of fresh ginseng showed no effect on killing cancer cell. It is assumed that inaccurate concentration of herbal acupuncture and fresh ginseng component could be the reason for this result. Therefore, future consideration will be studies on herbal acupuncture concentration.

  • BACKGROUND/OBJECTIVES: The aim of this study was to investigate the effects of exercise (EX) and Korean red ginseng (KRG) on inflammation mechanism in aging model rats with diet-induced atherosclerosis. MATERIALS/METHODS: Forty-eight male Sprague-Dawley rats were divided into 6 groups: Young control (Y-C), Aging control (A-C), A-C with HFD (AHF), AHF with EX (AHF-EX), AHF-EX with KRG (AHF-EX+RG), and AHF with KRG (AHF-RG). Aging was induced by D-gal (100mg/kg) and atherosclerosis was induced by HFD (60% fat) for 9 weeks. The experimental rats were performed swimming (60 min/day, 5 days/week) and supplied KRG orally (dose of 200 mg/kg) for 8 weeks. All rat aorta samples were harvested for biochemical and immunohistochemical analyses. REULTS: The EX and KRG supplementation significantly inhibited body weight and levels of TC, TG, LDL-C, and enhance of HDL-C compared with untreated AHF groups. AHF-EX, AHF-EX+RG, and AHF-RG group showed a decreased plasma CRP and increase plasma NO activities compared to AHF group. In addition, these groups revealed reduced 4-HNE, NF-kB, TNF-, ${\alpha}$, IL-6, COX-2, ICAM-1, VCAM-1 and enhanced eNOS expression in the aorta. CONCLUSION: These results suggest that EX alone, KRG alone, and combined treatment of EX and KRG may be an effective anti-inflammatory therapeutic for the atherosclerosis, possibly acting via the decreased of CRP and pro-inflammation proteins and the increased NO and eNOS.

  • Biotin is a water-soluble vitamin used as a skin conditioning agent and promotes the formation of intercellular lipid layers through increased lipid synthesis, which improves the skin's natural barrier function. The anti-inflammatory effects of biotin have been investigated using in vitro assay models, such as MTT assay, measurements of concentrations of nitric oxide(NO), prostaglandin E2(PGE$_2$), and inhibition rate of 5-lipoxygenase(5-LOX). In comparison with biotin, other plant extracts were tested at the same time which were kudzu vine extract, sage extract, paeonia extract, and dipotassium glycyrrhetinate. Nitric oxide is a signal molecule with functions such as neurotransmission, local vascular relaxation, and anti-inflammation in many physiological and pathological processes. NO can cause apoptosis and necrosis of target cells such as keratinocytes and is generated from L-arginine by nitric oxide synthase (NOS). Prostanoids, including prostaglandins and thromboxanes, are generated by the phospholipase $A_2$/cyclooxygenase(COX) pathway, and leukotrienes are generated by the 5-lipoxygenase pathway from arachidonic acid. Prostaglandin E2 recently have been shown to be beneficial in the resolution of tissue injury and inflammation, also has been implicated as an immunosuppressive agent and plasma levels of PGE$_2$ are elevated in patients sustaining thermal injury. Lipoxygenase metabolites from arachidonic acid have been implicated in inflammation, anti-inflammatory activity of the raw materials was evaluated in vitro by the offered inhibition of lipoxygenase.

  • Under constant environmental pollution, the incidence of Atopic Dermatitis (AD) caused by air pollutants and allergens has increased. AD is an allergy inflammatory skin disease characterized by pruritus, eczema, and skin dryness. In herbal medicine, Anemarrhena asphodeloides (Anemarrhenae Rhizoma; AR) has been utilized to treat Alzheimer's disease, osteoporosis, hypertension, and inflammation. The purpose of study evaluated the effect of AR in a mouse model of 2,4-dinitrochlorobenzene (DNCB)-induced AD-like skin lesions. After acclimatization for 5 days, the mice (6-week-old, male Balb/c) were divided into five groups (n=6/group): NC (normal control), DNCB (control), Dex (5 mg·kg-1, p.o.), AR100 (100 mg·kg-1, p.o.), and AR300 (300 mg·kg-1, p.o.). On days 1 and 3, 1% DNCB was applied to the skin and ears. After 4 days, 0.5% DNCB was applied once every 2 days for 2 weeks. Then, skin and ears eczema area and severity index (EASI); skin nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), and prostaglandin E2 (PGE2) levels; and plasma immunoglobulin E (IgE) levels were examined. The AR groups showed lower EASI, skin and ear thickness, mast cell count, and IgE levels than the control groups. Moreover, AR reduced iNOS, COX-2, and PGE2 levels. Therefore, AR possesses anti-inflammatory properties and can improve skin damage, indicating its therapeutic potential against AD.

  • 여드름은 사춘기와 젊은 연령층에서 나타나는 염증성 피부질환이다. Propionibacterium acnes (P. acnes)는 여드름에서 염증을 유발하는 주요한 균으로 알려져 있다. P. acnes 는 피부에서 과잉생산된 피지에 의해 막힌 모낭 내에서 증식하며, 피부 내의 단핵구를 활성화시키고 염증성 사이토카인(pro-inflammatory cytokine)의 분비를 촉진하여 염증반응을 증가시키는 것으로 알려져 있다. 본 논문에서는 Cnestis palala (Lour.) Merr. 추출물이 P. acnes 에 의한 염증반응을 감소시킬 수 있는지 확인하고자 하였다. 마우스 대식세포주인 RAW264.7 에서 C. palala 추출물은 P. acnes 에 의해 증가하는 염증성 사이토카인인 $IL-1{\beta}$의 단백질 발현량과 IL-6, $TNF-{\alpha}$, COX-2 의 mRNA 발현량을 감소시켰다. 또한 염증성 사이토카인 발현의 주요 전사인자(transcription factor)인 $NF-{\kappa}B$ 의 전사 활성 역시 C. palala 추출물에 의해 감소하는 것을 확인하였다. 따라서 C. palala 추출물이 P. acnes 에 의해 발생하는 여드름의 치료제나 그 보조제로 사용될 가능성이 있음을 제안 할 수 있다.
