  • This experimental study was carried out to evaluate the effects of Acanthopanacis cortex on Cytokine-inducing and and immune response in Mice. In order to investigate the effect of Acanthopanacis cortex, the following was performed; Cytotoxicity, in vitro, the fraction of $CD4^+$, $CD8^+$, $B220^+$ in splenic cell, gene expression of IL-12(p35), IL-12(p40), IFN-${\gamma}$, and splenic cell proliferation by Acanthopanacis cortex. Analysis of cytokine gene expression was carried out by RT-PCR amplification. Amplified PCR products were electrophoresed on 1.2% agarose gel, and the analysis (Ht) was used to 1D-density program. The results were obtained as follows. Acanthpanacis cortex showed didn't have cell toxicity under $12{\mu}g/m{\ell}$ group on mouse lung fibroblast cells. In an in vitro model using mouse peripheral blood mononuclear cells (PBMCs), extract of Acanthpanacis cortex induced multiple cytokine, including interleukin-12 (p35), interleukin-12 (p40), interferon-gamma (IFN-${\gamma}$). The extract also enhanced the percentages of the $CD4^+$, and $CD8^+$ in the untreated control were $22.1{\pm}3.3$ to $38.4{\pm}2.1$, and $5.0{\pm}0.4$ to $10.7{\pm}0.3%$, respectively. From above findings, it is suggested that Acanthopanacis cortex is able to anti-cancer and activate immune response system.

  • To determine effects of zinc on lipopolysaccharide (LPS)-induced production of proinflammatory cytokines and Iymphokines in tumor-bearing ICR mice, this study has been investigated. Zinc chloride (Zn) at doses of 1 mg/kg was administered orally 30 minutes before i.p. injection of LPS (8 mg/kg) 5 times for 7 days. LPS greatly increased tumor necrosis factor (TNF)-$\alpha$ and interleukin (IL)-1$\beta$, in both serum and splenic supernatants compared with those in controls. However Zn strongly decreased LPS-increased production of TNF-$\alpha$ and IL-1$\beta$ in spleenic supernatants compared with those in controls and insignificantly also reduced in serum. LPS insignificantly decreased IL-2 levels in spleenic supernatants compared with those in controls but significantly increased interferon (IFN)-${\gamma}$ levels. Zn didn't affect IL-2 production in splenic supernatants compared to controls but significantly enhanced the LPS-decreased production of IL-2. Zn significantly increased IFN-${\gamma}$ levels in splenic supernatants compared to controls and did not affect the LPS-increased production of IFN-${\gamma}$. These findings suggest that Zn may strongly attenuate the LPS-induced pathogenesis of proinflammatory cytokines in tumor-bearing state and significantly up-regulate the LPS-induced function of T cells to produce IL-2 with maintaining normally the LPS- increased levels of IFN-${\gamma}$.

  • Anti-inflammatory effects of dihydrobenzofuran neolignans isolated from Euonymus alatus leaves and twigs were evaluated in lipopolysaccharide (LPS)-stimulated RAW264.7 macrophage cells. Six neolignans, (+)-simulanol (1), (+)-dehydrodiconiferyl alcohol (2), (-)-simulanol (3), (-)-dehydrodiconiferyl alcohol (4), (+)-dihydrodehyrodiconiferyl alcohol (5), threo-buddlenol B (6) effectively inhibited the production of nitric oxide (NO) induced by LPS, and the activity of iNOS. (-)-dehydrodiconiferyl alcohol (4), which showed the most potent inhibitory activity, attenuated the activity of iNOS enzyme and also the expression of iNOS and COX-2 proteins. The subsequent production of pro-inflammatory cytokines, interleukin-$1{\beta}$, interleukin-6, tumor necrosis factor-${\alpha}$ and prostaglandin E2 were also inhibited by the pretreatment of RAW264.7 cells with (-)-dehydrodiconiferyl alcohol (4). These neolignans are thought to contribute to anti-inflammatory effects of E. alatus, and expected to be potential candidates to prevent/treat inflammation-related diseases.

  • Silibinin is the major active molecule of silymarin, the mixture of flavonolignans extracted from Cirsium japonicum (CJ). It has been used for treatment of hepatitis and inflammation related diseases. The aim of this study was to prove whether Silibinin has effectiveness for allergic inflammation. Silibinin processes the inflammatory reaction in phorbol 12-myristate 13-acetate (PMA) plus calcium ionophore A23187 (PMA plus A23187) stimulated human mast cell line (HMC-1). Its effect was examined by ELISA, RT-PCR, Western blot, and Luciferase assay. The results were Silibinin inhibited the expression of histamine, TNF-$\alpha$ (tumor necrosis factor-$\alpha$), IL-6 (interleukin-6), and IL-8 (interleukin-8). Silibinin suppressed NF-${\kappa}B$ (nuclear factor kappa B) activation in stimulated HMC-1 (human mast cell-1). This effect was mediated through inhibition of phosphorylation and degradation of $IkB{\alpha}$, an inhibitor of NF-kB. Silibinin significantly inhibited induction of NF-kB promoter mediated Luciferase assay. These results suggest that Silibinin has a potential molecule for therapy of mast cell-derived allergic inflammatory diseases.

  • Cheongpyesagan-tang (CP) is one of the traditional medicinal prescription to treat Taeumin (太陰人)'s disease. It has been commonly used for the treatment of stroke, arthritis, diabetes and obesity. In this study, we investigated an anti-inflammatory potential of CP water extract. We examined the effects of CP on the lipopolysarccharide (LPS)-induced production of nitric oxide (NO) and prostaglandin $E_2$ ($PGE_2$). We also examined the levels of protein or mRNA of inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2) and proinflammatory cytokines in RAW 264.7 cells. CP inhibited NO and $PGE_2$ production in a dose dependent manner and decreased the protein and mRNA expression of iNOS and COX-2. Also, CP decreased the mRNA expression of interleukin-6 (IL-6), interleukin-$1{\beta}$ (IL-$1{\beta}$), tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$). These results suggest that CP has potential as anti-inflammatory therapeutic medicine.

  • [Purpose] Strenuous exercise often induces skeletal muscle damage, which results in impaired performance. Sphingolipid metabolism contributes to various cellular processes, including apoptosis, stress response, and inflammation. However, the relationship between exercise-induced muscle damage and ceramide (a key component of sphingolipid metabolism), is rarely studied. The present study aimed to explore the regulatory role of sphingolipid metabolism in exercise-induced muscle damage. [Methods] Mice were subjected to strenuous exercise by treadmill running with gradual increase in intensity. The blood and gastrocnemius muscles (white and red portion) were collected immediately after and 24 h post exercise. For 3 days, imipramine was intraperitoneally injected 1 h prior to treadmill running. [Results] Interleukin 6 (IL-6) and serum creatine kinase (CK) levels were enhanced immediately after and 24 h post exercise (relative to those of resting), respectively. Acidic sphingomyelinase (A-SMase) protein expression in gastrocnemius muscles was significantly augmented by exercise, unlike, serine palmitoyltransferase-1 (SPT-1) and neutral sphingomyelinase (N-SMase) expressions. Furthermore, imipramine (a selective A-SMase inhibitor) treatment reduced the exercise-induced CK and IL-6 elevations, along with a decrease in cleaved caspase-3 (Cas-3) of gastrocnemius muscles. [Conclusion] We found the crucial role of A-SMase in exercise-induced muscle damage.

  • This study was designed to examine the immune response in Korean rockfish during water temperature fluctuation and to elucidate the factors contributing to streptococcal pathogenesis in cultured Korean rockfish, S. schlegeli. We investigated cumulative mortality against Streptococcus iniae (FP5228 strain) infection in the exposed Korean rockfish (39.7±5.8 g) to environmentally relevant temperature (Control, 23℃; High temperature, 28℃ and 23℃ and 28℃ with 12 hours interval exchange, 23↔28℃) for 48 hours. Also, the expression of the mRNA related to the immune response genes (heat shock protein 70, interleukin1β, lysozyme g-type and thioredoxin-like 1) were measured in spleen and head kidney by real-time PCR analysis in the exposed fish to thermal stress. In this study, the combined stress with bacterial challenge in fishes exposed to thermal stress lowered the survival rate than that of control (23℃). The cumulative mortality in the group of control, 28℃ and 23↔28℃ was 24%, 24% and 40% (P<0.05), respectively. Also, thermal stress modulated the mRNA level of immune related genes; heat shock protein 70, interleukin-1β, lysozyme g-type and thioredoxin-like 1 in Korean rockfish. The present study indicates that a high and sudden water temperature change affect immune responses and reduce the disease resistance in Korean rockfish.

  • 점막 상피는 외부 인자를 감지하는 최전선의 인식부위로서 외부스트레스 자극을 하부의 반응 신호로 전달하는 주요 세포이다. 리보솜독성 반응을 유발하는 데옥시니발레놀 (DON) 및 그 관련 곰팡이 독소는 푸자륨 곰팡이 오염에 의한 식중독성 소화기 염증성 질환과의 연관성이 알려 져 있다. 본 연구의 목적은 DON이 상피세포 감지 신호 전달 분자로서 PKR과 EGR-1이 관련 되고 이들이 상피세포에서의 염증성 사이토가인 인터루킨 8의 생성에 관련 된다는 가정 하에서 연구를 수행 하였다. PKR 발현의 세포내 작용 억제는 DON에 의해 유도되는 인터루킨 8의 생성을 감소시켰다. 또한 DON에 의한 IL-8 전사 활성화는 PKR 억제에 의하여 장관 상피세포에서 감소하였다. PKR 저해제의 처리는 EGR-1 promoter 활성, mRNA, 단백질 유도 등을 감소를 유발하였으며 MAP kinase (ERK1/2, p38, JNK)는 변화가 적거나 오히려 PKR 저해제의 전처리에 의하여 항진 되었다. 결론적으로 DON에 의해 자극된 감지신호인 EGR-1은 자체적으로 또는 PKR 신호를 경유하여 인터루킨8의 생산을 항진하는데 주요한 기능을 하였다. 이를 통하여 향후 리보솜 독성 반응과 관련된 소화기 염증유발의 주요한 기전을 제공하고 있다.

  • 스트레스가 위장관 기능을 변화시키며 이에는 interleukin과 시상하부-뇌하수체-부신피질 축이 관여한 다고 알려져 있다. 한편 우울증이 기능성 위장관 장애 및 interleukin과 연관성을 지닌다. 본 연구에서는 IL-$1\beta$, IL-2, IL-6의 혈청 농도를 기능성 위장관 장애 환자에서 측정하고, 혈청 cortisol 및 우울증과 스트레스의 정도를 조사하여 기능성 위장관 장애에 있어서 interleukin의 역할과 우울증 및 스트레스와의 상관성을 살펴보고자 하였다. 방법: 기능성 위장관 장애의 진단을 위한 로마기준 II에 따라 진단된 환자 20명과 건강한 대조군 20명을 대상으로 하였다. 채취한 혈액에서 혈청을 분리한 다음 Enzyme-linked Immunosorbent Assay 방법으로 혈청 IL-$1\beta$, IL-2, IL-6 농도를 측정하고 Fluorescence Polarization Immunoassay 방법으로 혈청 cortisol 농도 를 측정하였다. 우울증상의 정도를 Hamilton Rating Scale for Depression을 이용하여 평가하고, Schedule of Recent Experience를 이용하여 최근 일년간의 스트레스 생활사건의 양을 측정하여 비교하였다. 결과는 다음과 같다. 결과: 1) 기능성 위장관 장애 환자들의 혈청 IL-$1\beta$, IL-2 농도는 대조군에 비해 유의하게 낮았으나 혈청 IL-6 농도는 차이가 없었다. 2) 기능성 위장관 장애 환자군의 혈청 cortisol 농도는 대조군에 비해 유의하게 높았고, 우울증상도 유의하게 더 심하였으며, 스트레스 생활사건의 양 또한 유의하게 더 많았다. 3) 기능성 위장관 장애에서 우울증상의 정도와 혈청 cortisol 간에는 유의한 정상관관계가 있었다. 정도는 IL-$1\beta$와 역상관하는 경향이 있고, IL-2와는 정상관하였다. 스트레스 생활사건의 양파 혈청 cortisol 농도는 IL-6 와 유의하게 정상관하였다 대조군을 포함한 전 집단에서 IL-$1\beta$는 우울 정도, 스트레스 생활사건의 양, 혈청 cortisol 등과 유의하게 역 상관하였다. IL-6와 의하게 정상관하였다. 결론: 기능성 위장관 장애는 우울증 및 스트레스와 연관되며, 우울증, 스트레스가 심할수록 혈청 cortisol이 높았다. 기능성 위장관 장애 환자들에서 IL-$1\beta$, IL-2가 감소되어 있었지만, IL-6는 변화가 없었다. 상대적으로 증가된 혈청 cortisol이 IL의 변화와 관련될 수 있다고 생각된다.

  • Interleukin-17A (IL-17A) is a multifunctional cytokine which plays a crucial role in the initiation and progression of cancer. To date, several studies have investigated associations between IL-17A -197G>A (rs2275913) polymorphism and digestive cancer risk, but the results remain conflicting. We here aimed to confirm the role of this single nucleotide polymorphism (SNP) in susceptibility to digestive cancer through a systemic review and meta-analysis. Ten eligible case-control studies were identified by searching electronic databases, involving 3,087 cases and 3,815 controls. Odds ratios (ORs) and corresponding 95% confidence intervals (CIs) were used to estimate the strength of the association. The results of overall analyses indicated that the variant A allele was associated with an increased risk of digestive cancer (AA vs GG: OR=1.51, 95%CI=1.18-1.93; AA vs GG+GA: OR=1.45, 95%CI=1.12-1.87; A vs G: OR=1.21, 95%CI=1.05-1.39). In subgroup analysis stratified by specific cancer type, elevated risk among studies of gastric cancer was found (AA vs GG: OR=1.68, 95%CI=1.24-2.28; AA vs GG+GA: OR=1.62, 95%CI=1.16-2.26; A vs G: OR=1.23, 95%CI=1.04-1.46). According to ethnicity, there was evidence in the Asian populations for an association between this polymorphism and cancer risk (GA vs GG: OR=1.19, 95%CI=1.05-1.36; AA vs GG: OR=1.56, 95%CI=1.15-2.12; AA+GA vs GG: OR=1.28, 95%CI=1.13-1.44; AA vs GG+GA: OR=1.42, 95%CI=1.01-2.00; A vs G: OR=1.24, 95%CI=1.08-1.44), while in the Caucasian populations an association was found in the recessive model (AA vs GG+GA: OR=1.62, 95%CI=1.17-2.24). In conclusion, the results of this meta-analysis suggest that the IL-17A -197G>A polymorphism contributes to an increased risk of human digestive cancer, both in the Asian and Caucasian populations and especially for gastric cancer.
