  • $\beta$-l, 3-glucans are well known to enhance the immune reactions, resulting in antitumor, antibacterial, antiviral, anticoagulatory and wound healing activities. $\beta$-1, 3-glucans have various activities depending on molecular weight, degree of branching, conformation, water-solubility and intermolecular association. However, the $\beta$-1, 3-glucans linked backbone structure is essential and $\beta$-D-glucopyranosyl units are required for immunopotentiating activities. In this study, we tested the immunophamacological activities of insoluble $\beta$-1, 3-glucan from Agrobacterium sp. R259 KCTC 10197BP and confirmed the following activities: (1) IFN-${\gamma}$ production in PBMCs in the presence or in the absence of PHA, LPS, IL-18, and IL-12; (2) the induction of various cytokines in the spleen and thymus; (3) the adjuvant effect on the antibody production; (4) the cytotoxic and antitumor effects on cell lines and ICR mice. These results strongly suggest that $\beta$-1, 3-glucan from Agrobacterium sp. R259 KCTC 10197BP possesses various immunopharmacologica1 activities.

  • Hizikia fusiforme(sea weed fusiforme) has long been used for food source in this country. This study was performed to evalute the immunomodulative effects of Hizikia fusiforme (sea weed fusiforme) in mouse, using in vivo experiments. In vivo experiment, different concentration (0, 50, 500 mg/kg B.W.) of Hizikia fusiforme water extracts were orally administrated into mouse every other day for two weeks. The proliferation of mouse splenocytes, the production of three cytokines ($IL-1{\beta}$, IL-6, $TNF-{\alpha})$ secreted by activated macrophage. Splenocyte proliferation was enhanced in mouse orally administrated with 50 mg/kg B.W. and 500 mg/kg B.W. concentration compared to that of control group. Especially, the highest proliferation of spleoncyte was seen from the mouse orally administrated at the concentration of 50 mg/kg B.W. Also, the mouse of Hizikia fusiforme water extracts supplementation group in the both concentrations showed enhanced levels of cytokine production by activated peritoneal macrophages compared to those in control group. The highest level of cytokine ($IL-1{\beta}$, IL-6, $TNF-{\alpha})$ production was observed at 50 mg/kg B.W. supplementation group with LPS stimulation in all cases.

  • The purpose of this study was to investigate the effects of Violae Herba Water Extract (VH) on the proinflammatory factors of lipopolysaccharide (LPS)-induced on the production of inflammatory mediators in RAW 264.7 mouse macrophages cells. We examined effect of Violae Herba Water Extract on the cell viability of RAW 264.7 mouse macrophages cells. Futhermore, After 24 hours treatment we investigated anti-inflammatory effect of Violae Herba Water Extract by the production of Bio-Plex cytokine assay, concentrations of various cytokines such NO, $interleukin(IL)-1{\beta}$, tumor necrosis factor ${\alpha}(TNF-{\alpha})$ and IL-6. The water extract of Violae Herba significantly inhibited the production of NO, $IL-1{\beta}$, $TNF-{\alpha}$ and IL-6 at the concentration of 25, 50, 100 and $200{\mu}g/mL$ in the LPS-induced RAW 264.7 mouse macrophages cells with no changes in the cell viability of them. These results suggest that water extract of Violae Herba has anti-inflammatory effect related with its inhibition of proinflammatory cytokines such as $IL-1{\beta}$, $TNF-{\alpha}$ and IL-6 in the LPS-induced RAW 264.7 mouse macrophages cells. Further research is needed to develop therapeutic agents for inflammatory diseases using Violae Herba.

  • Rheumatoid arthritis is characterized by the focal loss of cartilage due to an up-regulation of inflammatory pathways, which produce inflammatory mediators, such as interleukin-1beta(IL-$1{\beta}$), IL-6, tumour necrosis factor alpha(TNF-$\alpha$), prostaglandin, and nitric oxide(NO). We investigated the anti-arthritic effects of water extract from FLOS LONICERAE(FLWE) in vitro and in vivo. Extract inhibited the production of inflammatory mediators(NO, IL-$1{\beta}$, TNF-$\alpha$, and prostaglandin $E_2$) and the expression of inducible NO synthase(iNOS) and cyclooxygenase-2(COX-2) in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages in a dose-dependent manner. FLWE also inhibited TNF-$\alpha$, IL-$1{\beta}$, IL-6, and $PGE_2$ production as well as COX activity in collagen-induced mouse arthritis. Moreover, FLWE significantly suppressed collagen-induced mouse arthritis. These results suggest that FLOS LONICERAE may be useful for therapy against inflammatory immune diseases and rheumatoid arthritis, probably by suppressing the production of inflammatory mediators.

  • Zinc plays an important role in immunobiological responses, while excessive zinc attenuates immune functions in a dose-dependent manner. Zinc excess has been reported to increase levels of plasma prostaglandin E$_2$ (PGE$_2$), which is known to inhibit production of Th (helper T) 1-associated cytokines and to induce inflammatory responses. Thus, this study was investigated the effects of indomethacin, a potent inhibitor of PGE$_2$ synthesis, on the proinflammatory cytokine and lymphokine production in ICR mice exposed to excessive zinc. Indomethacin at doses of 5 mg/kg was administered i.p. 30 minutes before zinc chloride (Zn) 30 mg/kg orally daily for 10 days. Excessive Zn remarkedly increased tumor necrosis factor (TNF)-$\alpha$ and interleukin (IL)-1$\beta$ levels in both serum and splenic supernatants compared with those in controls, while indomethacin significantly reduced the excessive Zn-induced levels of IL-1$\beta$. In serum, excessive Zn significantly decreased the levels of IL-2 and interferon (IFN)-${\gamma}$ compared with those in controls, whereas indomethacin significantly enhanced the excessive Zn-decreased levels of IFN-${\gamma}$ but did not affect the Zn-decreased levels of serum IL-2. In splenic supernatants, All of excessive Zn, indomethacin, and combination of Zn and indomethacin significantly enhanced IL-2 levels compared with those in controls, but indomethacin didn't affect the Zn-induced production of IL-2. These data, therefore, suggest that indomethacin significantly attenuated the in vivo and ex vivo IL-1$\beta$ production increased by excessive zinc and remarkedly enhanced the in vivo excessive zinc-suppressed production of IFN-${\gamma}$ but not IL-2.

  • This experiment was carried out in order to separate bovine colostral whey protein from Imsil province and to test the effect of immunological activity on RAW 264.7 cells. The colostral whey protein contained TGF-${\beta}$ 7, 475 pg/g in total. We first tested the effect of the colostral whey protein on the proliferation of RAW 264.7 cells and it demonstrated cytotoxicity at concentrations greater than 20 mg/mL. Therefore, the immunological activities of colostral whey protein were investigated in maximum concentration of 10 mg/mL on LPS-induced RAW 264.7 cells. Results indicated that colostral whey protein inhibited the LPS-induced nitric oxide (NO) production in a dose-dependent manner. The colostral whey protein also suppressed the productions of proinflammatory cytokines (TNF-${\alpha}$, IL-$1{\beta}$, IL-6) in a dose-dependent manner. In addition to the immunological activity, colostral whey protein led to the expression of heme oxygenase-1 (HO-1) in RAW 264.7 cells. In conclusion, colostral whey protein containing TGF-${\beta}$ inhibited the production of NO, TNF-${\alpha}$, IL-$1{\beta}$, and IL-6 via expression of HO-1.

  • It has been focused on the importance of the host inflammatory response in periodontal pathogenesis and progression, treatment has been introduced to control the host response and the method, which diminishes production and activity of MMP by doxycycline, has been used in periodontal field. MMP is a proteolytic enzyme which plays a major role in tissue destruction and MMP-1 is secreted in the periodontally healthy tissue, while MMP-8, 9, 13, etc in the inflammatory state. Among these, MMP-13 has been discovered lately and reported to degrade primarily type II collagen. Periodontal ligament (PDL) cell plays a role in destruction of periodontal tissue. This study was to evaluate the effect of doxycycline and mefenamic acid, non-steroidal antiinflammatory drug on MMP-13 mRNA expression in the rat PDL cell. Doxycycline concentration of $1{\sim}100\;{\mu}g/ml$ was added rat PDL cell and cell activity was measured by MIT assay at day 1 and 3. MMP-13 gene expression was evaluated by RT-PCR after PDL cells were pre-treated for 1hour with doxycycline (50 ${\mu}g/ml$) alone or with mefenamic acid ($10^{-6}M$), then added $IL-1{\beta}$(1.0 ng/ml) and incubated for 16-18 hours. The results are as follows: 1. Cell activity decreased Significantly at 24 and 72 hours in 100 ${\mu}g/ml$ (p<0.05). 2. Level of MMP-13 mRNA was in 20.2% increase by $IL-1{\beta}$ and in pre-treating doxycycline group, expression of $IL-1{\beta}$ induced MMP-13 mRNA was inhibited by 31% than $IL-1{\beta}$ treated only. 3. Mefenamic acid did not inhibit on the expression of $IL-1{\beta}$ induced MMP-13 mRNA, while mefenamic acid in combination with doxycycline inhibited the expression by 41% compared to only $IL-1{\beta}$ stimulation. These results suggest that doxycycline synergistically inhibit the expression of $IL-1{\beta}$ induced MMP-13 mRNA in combination with mefenamic acid.

  • In this study, ${\beta}$-1,3/1,6-glucan, lactic acid bacteria, and ${\beta}$-1,3/1,6-glucan+lactic acid bacteria were tested for 10 weeks using an immunodeficient animal model infected with LP-BM5 murine AIDS virus On the immune activity. Cytokines production, plasma immunoglobulin concentration, T cell and B cell proliferation were measured. As a result, the T cell proliferative capacity which was weakened by immunization with LP-BM5 murine AIDS virus increased significantly T cell proliferative capacity compared with the red ginseng control group. B cell proliferative capacity was significantly higher than the infected control group. Increased B cell proliferation was reduced. In the cytokine production, IL-2, IL-12 and IL-15 in the Th1-type cytokine increased the secretion of IL-2, IL-12 and IL-15 compared to the infected control. The proliferative capacity of the treated group was higher than that of the mixed treatment group. TNF-${\alpha}$ was significantly decreased compared with the infected control group. The IL-4, IL-6 and IL-10 levels were significantly inhibited in the infected control group and the Th1/Th2 type cytokine expression was regulated by immunohistochemistry. IgE, IgA, and IgG levels were significantly lower in the immunoglobulin secretion assay than in the control. As a result, the immunomodulatory effect of ${\beta}$-1,3/1,6-glucan+lactic acid bacteria was confirmed by mixing with LP-BM5 murine AIDS virus-infected immunodeficient animal model.
