  • Lipopolysaccharide (LPS)-induced inflammatory responses in the HaCaT keratinocyte cell line produce proinflammatory cytokines, such as interleukin-1${\alpha}$(IL-1${\alpha}$), tumor neurosis factor-${\alpha}$ (TNF-${\alpha}$), interleukin-6 (IL-6), and interleukin- 8 (IL-8) and also increase the expression of inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), and prostaglandins E2 (PGE2). In this study, we developed new natural ingredients for cosmetics that inhibit the pro-inflammatory responses induced by LPS in HaCaT cells. The mixture of Sorbus commixta (SC), Urtica dioica (UD), Phyllostachys nigra (PN), and Rhus semialata gall (RS) extracts blocked the increase of TNF-${\alpha}$ IL-1${\alpha}$ IL-6, and IL-8. The increase of COX-2, iNOS, and PGE2 were also blocked by it. Finally, the mixture inhibited skin irritation induced by sodium lauryl sulfate (SLS), when applied on skin through IQ chamber$^{(R)}$. In conclusion, these results show that the mixture of SC, UD, PN, and RS can be used as a primary ingredient to alleviate skin irritation when cosmeceutical products are developed for sensitive skin.

  • Objective: This study was eanied out to investigate the effects of Raphani Semen on immuno-response in the mouse model of allergic asthma. Methods: In this study, BALB/C mice were divided into 6 groups: Normal (Non-treated group), Control (Group with not treated after allergic sensitization and induction by ovalbumin), Treat I (Group with the oral administration of saline after allergic sensitization and induction by ovalbumin), Treat n (Allergic asthma group treated with acupuncture (BL 13)), Treat III (Allergic asthma group treated with the oral administration of Raphani Semen) and Treat lV (Allergic asthma group treated with the herbal-acupuncture of Raphani Semen (BL 13)). The effect on cytokine was assessed by measuring cytokine (lL-2, IL-4, IL-5, IL-10, IL-12, IFN-r) in bronchoalveoar lavage fluid(ELISA). ResuJts : The results obtained as follows: 1. The production of Interleukin-2 was decreased significantly in Treat I group, Treat n group and Treat IV group as compared with Control group. 2. The production of Interleukin-4 was decreased significantly in Treat I group, Treat II group and Treat IV group as compared with Control group. Among them. the production of Interleukin-4 was decreased remarkably in Treat IV group as compared with other groups. 3. The production of Interleukin-5 was decreased significantly in Treat I group and Treat IV group as compared with Control group. 4. The production of Interleukin-10 was decreased significantly in Treat I group and Treat III group as compared with Control group. 5. The production of Interleukin-12 was all decreased significantly in Treat I group, Treat n group, Treat m group and Treat IV group as compared with Control group. 6. The production of Intelferon- showed no significant changes in Treat I group, Treat n group. Treat m group and Treat Ⅳ group as compared with Control group. Conclusion: These results show that the production of Interleukin-4, 5 was decreased significantly in aJlergic asthma group treated with the herbal-acupuncture of Raph Semen (BL 13), It is known that inactivity of Th2 cell constrained the revelation and controlled hypersenstive action. As to this mechanism, it is suggested that the herbal-acupuncture of Raphani Semen(BL 13) constrained the revelation of allergic asthma.

  • Sanyeoleumja (SY) is the traditional Korean medicinal prescription for the treatment of inflammatory diseases of eyes. In this study, the anti-inflammatory effects of SY water extract were investigated. To measure the anti-inflammatory effects of SY, we examined the productions of inflammatory factor including nitric oxide (NO), prostaglandin E2 (PGE2), inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), interleukin-6 (IL-6), interleukin-1β (IL-1β) in lipopolysaccharide (LPS)-induced RAW 264.7 cells. SY inhibited NO and PGE2 production in a dose dependent manner and decreased the protein and mRNA expression of iNOS and COX-2. Also, SY decreased the mRNA expression of interleukin-6 (IL-6) and interleukin-1β (IL-1β). In conclusion, SY downregulated LPS-induced inflammatory factor productions, which could be a clinical basis for inflammatory diseases.

  • To examine the role of protein kinase C (PKC) in regulation of interleukin-1 beta (IL-1$\beta$)-induced iNOS expression, IL-1$\beta$-induced nitrite production was observed in cultured vascular smooth muscle (VSM) cells pretreated with phorbol 12-myristate 13-acetate (PMA) and phorbol 12,13-butyrate (PDB) as PKC activator; 4$\alpha$-phorbol-didecanoate (PDD) as PKC non-activator. Nitrite production induced by IL-1$\beta$ was increased by the presence of increasing concentration of PMA ranging from 2 to 200 nM. However, in VSM cells pretreated with PMA and PDB, IL-1$\beta$-induced $NO_2$ production was decreased in proportion to the duration of pretreatment, and most significantly decreased in pretreatment time of 24 hours. Using RT-PCR method, the expression of iNOS mRNA induced by IL-1$\beta$ was decreased in VSM cells pretreated with PMA 200 nM for 24 hours. These results suggest that decrease in IL-I$\beta$-induced nitrite production by the pretreatment of PMA result from inhibition of iNOS expression and the inhibition related to PMA-induced PKC down-regulation.

  • 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.

  • We have identified a T cell-activating material in the culture supernatant of Streptomyces species. The factor in microbial culture supernatant (MCS) induced thymocyte proliferation in a does dependent fashion and it could be detected by immunoblot analysis using anti-interleukin-1(IL-1) antibody. The factor in MCS was slightly larger(about 21 kd) in its molecular weight than IL-1 on SDS-PAGE. When 125I-MCS was covalently coupled with homo-bifunctional cross-linking agent, disuccinimidyl-propionate to IL-1 receptor(IL-1R) on mouse thymoma cell(EL-4) and immunoprecipitated with anti-IL-1R antibody the molecular weight of this complex of 110 kd was observed.

  • The protective effects of extract powder of Angelica gigas on the degeneration of the articular cartilage in rats was investigated with monosodium iodoacetate (MIA)-induced osteoarthritis, The treatment of high concentration (50 μg/mL) of Angelica gigas effectively inhibited nitric oxide (NO) production induced by interleukin-1α (IL-1α) without any cytotoxicity. Specifically, mRNA and protein expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) were dose dependently reduced by extract powder of Angelica gigas. Importantly, mRNA expression in articular cartilage of inflammatory cytokines, tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β) and interleukin-6 (IL-6) were clearly reduced. The inflammatory cytokines in blood were also reduced as well. These results suggested that the protective effects on the degeneration of the articular cartilage was derived from the inhibitory effects of mRNA and protein expression of tested inflammatory cytokines which is linked to prevent the degradation of proteoglycan (PG), the main matrix content in articular cartilage. Meanwhile, the 2 hrs incubation of decursin, a major compound of extract powder in rat whole blood rapidely converted decursin into decursinol which shows string anti-inflammatory activity. The coverted decursinol was detected after 8 hrs in whole blood by LC-MS/MS. Conclusively, the inhibitory effects of inflammatory cytokines production in osteoarthritis may be derived from the production of decursinol, which performs against inflammatroy cytokines like TNF-α, IL-1β, and IL-6.

  • Objectives : Daucus carota sativa has been frequently used as food supplements in many of the Asian countries, and a nutritional medical drug in traditional medicine. This research investigated the effects of Daucus carota sativa extract (DCE) on acute phases of inflammation in Raw 264.7 cells treated with lipopolysaccharide (LPS) in terms of the inhibition of nitric oxide (NO), prostaglandin $E_2$ ($PGE_2$) and pro-inflammatory cytokines production. Methods : NO, $PGE_2$, tumor necrosis factor (TNF)-${\alpha}$, interleukin-$1{\beta}$ and interleukin-6 contents were assayed by ELISA, and expressions of inflammation-related proteins such as inducible NO synthase (iNOS) were determined by immunoblot analyses. Results : DCE treatment attenuated the LPS ability to increase the productions of NO and $PGE_2$ as well as the protein level of iNOS in a concentration-dependent manner. Consistently, treatment of the cells with DCE suppressed the production of TNF-${\alpha}$, interleukin-$1{\beta}$ and interleukin-6. DCE also caused decreases of inhibitor of ${\kappa}B{\alpha}$ phosphorylation induced by LPS in the cells, which means DCE inhibition of NF-${\kappa}B$ activity. Furthermore, DCE blocked LPS-induced phosphorylation of p38 and SAPK/JNK. Conclusion : This study showing here may be of help to understand the action mechanism of DCE, and provide the information for the medical use of Daucus carota sativa for the inflammatory disease.

  • Interleukin-1 (IL-1) is one of the proinflammatory cytokines, after IL-1 binds to IL-1RI, IL-1RacP (interleukin-1 receptor accessory protein) joins with IL-1/IL-1RI to form a complex, and leading to cell activation. IL-1RAcP is involved in immune response, stress and apoptosis. The purpose of this study was to investigate the gene expression of IL-1RAcP in red seabream (Pagrus major) exposure to low water temperature (8℃, 33 psu) and low salinity (20℃, 10 psu). Results showed that, the expression of IL-1RAcP was significantly increased in the experiment groups, such as low water temperature (8℃, 33 psu), and low salinity (20℃, 10 psu). These results suggest that IL-1RAcP was played roles in biomarker gene on the environmental stress such as low water temperature and low salinity.
