Objective : This study was performed to estimate the effects of OMC-2010 extract on cytokine production in mouse spleen cells. Methods : Mouse spleen cells were pre-treated with ethanol and water extract of OMC-2010 for 1 h, then stimulated with lipopolysaccharide (LPS, 1 μg/ml) for 48 h. Then the cells were harvested for real-time reverse transcription polymerase chain reaction to detect cytokines. Results : OMC-2010 ethanol extract significantly inhibited the LPS-induced interleukin (IL)-1beta, tumor necrosis factor (TNF)-alpha and IL-5 mRNA expressions, but not shown such changes in IL-6, IL-4, IL-13. OMC-2010 water extract significantly inhibited the LPS-induced TNF-alpha, and IL-5 mRNA expressions, but not shown such changes in IL-1beta, IL-6, IL-4, IL-13. Conclusions : Theses results could suggest that both ethanol and water OMC-2010 extract could inhibit the TNF-alpha and IL-5 mRNA expression.

본 연구에서는 고종시 감껍질을 열수 추출 및 초임계 유체 추출하여 아토피 피부염 증상 억제 효과를 밝히고, 항염 효능을 나타내는 기능성 소재로서의 이용 가능성을 알아보고자 하였다. 그 결과 육안 평가를 통해 피부의 홍반(erythema), 가려움과 피부의 건조상태(pruritus and dry skin), 부종과 혈종(edema and excoriation), 짓무름(erosion), 그리고 태선화(lichenification)와 같은 아토피 피부염 같은 증상이 AD 모델에서 증가하였지만, SPPE와 PPWE를 투여하였을 경우 완화되는 것을 확인할 수 있었으며, SPPE가 PPWE보다 더 뛰어난 효과를 나타내었다. 피부 두께와 염증 세포의 침윤은 AD 모델에서 크게 증가하였지만, SPPE와 PPWE를 투여하였을 경우 감소하는 것을 확인할 수 있었으며, SPPE가 PPWE보다 더 뛰어난 효과를 나타내었다. 혈청 중의 IgE와 IL-4의 수치를 측정한 결과, AD 모델에서 크게 증가하였으나 SPPE와 PPWE를 투여하였을 경우 감소하는 것을 확인할 수 있었으며, SPPE가 PPWE보다 더 뛰어나게 억제하는 효과를 나타내었다. 또한 RAW264.7 세포에 SPPE를 처리하였을 경우 염증매개 인자인 NO, PGE2, IL-6, IL-1β의 생성량이 유의적의로 감소하였고, PPWE의 경우 NO, PGE2, IL-1β의 생성을 억제한 반면 IL-6 생성 억제에는 영향을 나타내지 않았다. 이러한 염증 매개인자 억제 효능은 SPPE가 PPWE보다 더 뛰어나게 억제하는 것을 확인하였다. 따라서 감껍질 추출물은 아토피 피부염 증상 개선과 염증관련 질환 치료를 위한 기능성 천연물 소재로 유용하게 활용될 수 있을 것으로 판단된다. This study aimed to investigate the anti-atopic effect of hot water (PPWE) and supercritical-carbon dioxide fluid extract of persimmon peels (SPPE) on atopic dermatitis (AD)-like skin lesions in hairless mice. Histological analyses demonstrated that SPPE treatment more strongly inhibited the dermal infiltration of inflammatory cells in AD-like skin lesions than that by PPWE. Compared to PPWE, SPPE significantly decreased the dermatitis clinical score and the epidermal thickness and potently suppressed serum IgE and interleukin (IL)-4 production in hairless mice with AD. Furthermore, compared to PPWE, SPPE potently inhibited the production of nitric oxide, prostaglandin E₂, and proinflammatory cytokines such as IL-6 and IL-1β in lipopolysaccharide-stimulated RAW264.7 macrophages. These results suggested that SPPE exhibited anti-atopic dermatitis activity via the regulation of inflammatory responses.

Background: Nitric oxide (NO), a cytotoxic molecule is produced in various tissues including tumor cells during interleukin-2 (IL-2) therapy . Lymphokine-activated killer (LAK) cells are induced during IL-2 therapy, and have cytotoxic activity against tumor cells. The current study investigated the effects of NO synthesized in target cells or exposure of target cells to NO on the sensitivity of target cells to LAK cell cytotoxicity. Methods: Cytotoxicity was measured using 4 h chromium release assays. LAK cells which were induced by a 4 day incubation of BALB/c mouse splenocytes with IL-2 (6,000 IU/mL) were employed as effector cells. RD-995 skin tumor cells originated from a C3H/HeN mouse were employed as target cells. NO synthesis in target cells was induced by a 24 h incubation of RD-995 cells with $IFN{\gamma}$ (25 U/mL), TNF (50 U/mL) and IL-1 (20 U/mL). S-nitrosyl acetylpenicillamine (SNAP), an NO donor, was used to expose target cells to NO. $N^G$-monomethyl-L-arginine (MLA) and carboxy-PTIO were added during cytotoxicity assays to inhibit NO synthesis, and to scavenge NO produced by target cells, respectively. Results: Sensitivity of NO-producing RD-995 cells to LAK cell cytotoxicity was decreased by addition of MLA and carboxy-PTIO during cytotoxicity assays. However, the two reagents had no effect on the sensitivity of non-NO-producing RD-995 cells. Pretreatment of RD-995 target cells with SNAP increased the sensitivity in comparison with untreated cells. Conclusions: Sensitivity of target cells to LAK cell cytotoxicity is increased by target cell NO synthesis or exposure to NO. Further studies are needed to evaluate whether these in vitro results have relevance to in vivo phenomena.

Park, Sang-Yong,Shin, Heon-Sub,Yang, Jung-Eun,Han, Sang-No,Kim, Dae-Sung,Kim, Myong-Jo,Heo, Seong-Il,Yi, Tae-Hoo,Lee, Jung-Min The Plant Resources Society of Korea 2012 한국자원식물학회지 Vol.25 No.6

Sea Buckthorn (Hippophae rhamnoides L.) has been used in traditional medicine for the treatment of cough, indigestion, circulatory problems and pain. The associated anti-inflammatory effect of this agent is achieved via the inhibition of Nf-${\kappa}B$ signaling, a property that has been demonstrated to effectively control the symptoms of various skin disorders, including atopic dermatitis. Accordingly, the purpose of this study was to assess the efficacy of Sea Buckthorn in reducing the production of lipopolysaccharide (LPS) activated nitric oxide (NO) by inhibiting the Nf-${\kappa}B$ pathway, as measured by the symptoms of atopic dermatitis (AD) occurring secondarily to inflammation and immune dysregulation. Our data demonstrate that Sea Buckthorn significantly decreased the LPS-induced production of NO (p<0.001). Atopic dermatitis was induced by repeated application of 2,4-dinitrochlorobenzene to the dorsal skin of mice. Topical application of 5% Sea Buckthorn extract improved the symptoms of AD, specifically reducing disease severity scores, scratching behaviors and epidermal thickness. When compared to the control group, animals treated with Sea Buckthorn exhibited increased serum IL-12 levels and decreased serum TNF-${\alpha}$, IL-4 and IL-5 levels. Such a modulation of biphasic T-helper (Th)1/Th2 cytokines may result in a reduction in serum IgE levels. Our findings suggest that mechanism of action of Sea Buckthorn in the treatment of AD is associated with a marked anti-inflammatory effect as well as an inhibition of Th2-mediated IgE overproduction via the modulation of biphasic Th1/Th2 cytokines. Such results suggest that topical Sea Buckthorn extract may prove to be a novel therapy for AD symptoms with few side effects.

Background : Loss of bone mass is usually detected after BMT. The causes of bone loss are related with gonadal dysfunction and immunosuppressants. Cytokines, especially IL-6, play an important role in the pathogenesis of postmenopausal osteoporosis. However, the pathogenetic role of cytokines in post-BMT bone loss is unknown and data on the changes of cytokines in accordance with bone turnover markers are scarce. The aim of this study is to assess the relationship of bone turnover markers and cytokines of peripheral blood and bone marrow before and after allogeneic BMT. Methods : This prospective study included two analyses. The first was a study of 46 BMT recipients, examining the relationship between bone turnover markers and cytokines of serum which were measured before and 1, 2, 3, 4 week and 3 months after BMT. The second was a study of 14 BMT patients, measuring bone marrow plasma cytokines such as IL-6 and TNF-? at post-BMT 3 week and bone turnover marker at the same time to assess the relationship beween two parameters. Results : Serum ICTP, bone resorption marker, increased progressively until 4 weeks (peak) after BMT and then decreased thereafter. Serum osteocalcin, bone formation marker, decreased progressively until 3 weeks after BMT and then increased thereafter. There was positive correlation between serum ICTP and bone marrow IL-6 levels at the post-BMT 3 week with a statistical significance, but the correlation between bone turnover markers and bone marrow TNF-? or peripheral blood cytokines was not found. Conclusion : Our data suggest that the progressive increase of bone resorption after BMT is related with the increase of bone marrow IL-6, which is a potent stimulator of bone resorption in vivo(J Kor Soc Endocrinol 15:85-96, 2000).

Although there has been a steady increase in the prevalence of food allergies worldwide in recent decades, no effective therapeutic strategies have been developed. Modulation of the gut microbiota composition and/or function through probiotics has been highlighted as a promising target for protection against food allergies. In this study, we aimed to investigate the allergy-reducing effects of a probiotic mixture (P5: Lactococcus lactis KF140, Pediococcus pentosaceus KF159, Lactobacillus pentosus KF340, Lactobacillus paracasei 698, and Bacillus amyloliquefaciens 26N) in mice with ovalbumin (OVA)-induced food allergy. Administration of P5 significantly suppressed the oral OVA challenge-induced anaphylactic response and rectal temperature decline, and reduced diarrhea symptoms. Moreover, P5 also significantly inhibited the secretion of IgE, Th2 cytokines (interleukin (IL)-4, IL-5, IL-10, and IL-13), and Th17 cytokines (IL-17), which were increased in mice with OVA-induced food allergy, and induced generation of CD4+Foxp3+ regulatory T cells. These results revealed that P5 may have applications as a preventive agent against food allergy.

<P><I>Lonicera japonica THUNB.</I>, which abundantly contains polyphenols, has been used as a traditional medicine for thousands of years in East Asian countries because of the anti-inflammation properties. This study aimed to investigate the anti-inflammatory mechanism of polyphenol components isolated from Korea <I>L. japonica T.</I> by nuclear factor-kappaB (NF-<I><I>κ</I></I>B) and mitogen-activated protein kinases (MAPKs) pathway. Polyphenols significantly decreased lipopolysaccharide- (LPS-) induced mRNA and protein expression of inducible nitric oxide synthase and cyclooxygenase-2, as well as mRNA expression of tumor necrosis factor-alpha, interleukin- (IL-) 1<I><I>β</I></I>, and IL-6. Moreover, polyphenols inhibited nuclear translocation of NF-<I><I>κ</I></I>B p65, phosphorylation/degradation of the inhibitor of <I><I>κ</I></I>B, and phosphorylation of p38 MAPK, whereas the extracellular signal-regulated kinase and Janus N-terminal kinase were not affected. These results indicate that polyphenol components isolated from Korea <I>L. japonica T.</I> should have anti-inflammatory effect on LPS-stimulated RAW 264.7 cells through the decrease of proinflammatory mediators expression by suppressing NF-<I><I>κ</I></I>B and p38 MAPK activity.</P>
