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

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.

Objectives : This study was carried out to know the anti-osteroarthritic effects of Bangkibokryeong-tang(Fanjifuling-tang(BBT)) on the papain-induced osteoarthritis C57BL/10 mouse. Methods : Osteoarthritis was induced by injection of papain(6 ${\mu}l$) into knee joint of mouse. Osteoarthritic mice were divided into 4 groups(normal, control, joins(R), BBT). The injection did not fit the normal group. A week later, after the injection of papain, control group was taken normal saline 200 ${\mu}l$, positive control group was taken joins(R)(100 mg/kg), treated group was taken extract of Bangkibokryeong-tang(Fanjifuling-tang(BBT))(400 mg/kg). After then, we examined hepatotoxicity, nephrotoxicity, inflammation cytokines, expression of inflammation factor mRNA, hemotology, histology through the micro CT-arthrography, and etc. Results : 1. Hepatotoxicity and nephrotoxicity have not expressed. 2. The levels of IL-$1{\beta}$, TNF-${\alpha}$, IL-6, MCP-1, Thromboxane B2, Leukotriene B4, Prostaglandin E2 in serum were significantly decreased. 3. In hematology, the levels of neutrophils and monocytes were significantly decreased. 4. The expression of inflammation factor mRNA like TNF-${\alpha}$ and IL-6, COX-2, iNOS-II were significantly inhibited. 5. In micro CT-arthrography, cartilage volume was less decreased. 6. The degree of osteoarthritis induced damage of joint of BBT group is low in histopathologic observation(hematoxylin&eosin(H&E), Safranin-O). Conclusions : According to this study, BBT has effect of anti-osteoarthritis. Further clinical research for the cartilage protective effect is necessary.

Obesity, which is characterized by a state of mild chronic inflammation, is known to cause metabolic diseases. This study was carried out to investigate the effect of lyophilized dropwort vinegar powder (DVP) on adipocyte differentiation and inflammation in T3-L1 preadipocyte and RAW 264.7 macrophage cell lines. DVP inhibited the differentiation of 3T3-L1 preadipocytes induced by a mixture of IBMX, dexamethasone, and insulin (MDI). Western blot analysis of cell lysates showed that DVP decreased the levels of two major transcription factors involved in adipogenesis, peroxisome proliferator- activated receptor-${\gamma}$ (PPAR-${\gamma}$) and CCAAT-enhancer-binding protein ${\alpha}$ ($C/EBP{\alpha}$). DVP also significantly suppressed lipopolysaccharide (LPS)-induced production of nitric oxide (NO), and this was accompanied by a decrease in inducible NO synthase (iNOS) and cyclooxygenase-2 (COX-2) protein expression. These results demonstrate that DVP inhibits MDI-induced adipocyte differentiation of 3T3-L1 cells and LPS-induced inflammation in RAW 264.7 macrophage cells. The findings indicate that this natural product may be a good candidate as to prevent metabolic diseases.

Objectives : This study was to investigate the anti-oxidative and anti-inflammatory effect of Lonicera japonica water extracts (LE) on Ulcerative Colitis Induced by DSS (Dextran Sulfate Sodium) in Mice. Methods : Colitis was induced by DSS in Balb/c mice. The sample group was divided into three. The mice in control group were not inflammation-induced. The pathological group was composed of untreated colitis elicited mice. The experimental group was administered Lonicera japonica water extracts (LE) after colitis elicitation. The effects on ulcerative colitis were evaluated the anti-oxidant effect, inhibition of COX-2 mRNA expression, the morphological change of colonic mucosa, decrease effect of HSP 70 and COX-2 in mucosa. Results : The SOD ability of LE was dose-dependently increased and the LPS-induced COX-2 mRNA expression of LE was dose-dependently decreased. LE showed the protective effects on DSS-induced experimental colitis. LE inhibited shortening of colon length, the hemorrhagic erosion in colonic mucosa. LE also showed the decrease effect for HSP70 and COX-2 in mucosa. Conclusions : The current results demonstrate the clinical utility of LE in traditional medicine and indicate the possible treatments for ulcerative colitis from natural products. Further investigations for exact mechanisms will be needed.

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.

Acne is an inflammatory skin disease that occurs in puberty and young people. Propionibacterium acnes (P. acnes) is known to be a major cause of inflammation in acne. P. acnes proliferates within hair follicles blocked by overproduced sebum in the skin, and thereby activates monocytic cells to promote the secretion of pro-inflammatory cytokines. In this study, we investigated the possibility of Cnestis palala (Lour.) Merr. extract to diminish P. acnes-mediated inflammatory responses. We found that C. palala extract significantly attenuated P. acnes-induced pro-inflammatory cytokine expressions, such as $IL-1{\beta}$, IL-6, $TNF-{\alpha}$, iNOS, and COX-2 in mouse macrophage RAW264.7 cells. Moreover, we observed that C. palala extract inhibited $NF-{\kappa}B$ transcriptional activation, which is the major transcription factor of inflammatory cytokine expression. Therefore, it is expected that C. palala extract has a potential as a therapeutic agent or supplement for the treatment P. acnes-induced inflammatory responses.
