Antiallergic and antipsoriatic effects of korean Red Ginseng (KRG, steamed root of panax ginseng C.A. Meyer, Family Araliaceae) were measured. Orally administered KRG water extract potently inhibited passive cutaneous anaphylaxis (PCA). KRG water extract also showed the potent inhibition in oxazolone-induced mouse dermatitis, and suppressed mouse ear swelling by $39\%$ at 16 days at a dose of $0.1\%$. KRG water extract reduced the levels of mRNA of cyclooxygenase (COX)-2, $IL-1\beta$, $TNF-\alpha$ and $INF-\gamma$ increased in oxazolone-applied mouse ears, however, did not inhibit that of IL-4. KRG water extract also inhibited iNOS and COX-2 mRNA expression level of RAW264.7 cell induced by lipopolysaccharide. Based on these findings, we suggest that KRG can improve atopic and contact dermatitis by the regulation of $ IL-1\beta$ and $TNF-\alpha$ produced by macrophage cells and $interferon-\gamma$ produced by Th1 cells.

Objectives : The purpose of this study was to investigate anti-cancer effects of various ginseng herbal acupuncture in mice and expression of cytokine mRNA. Methods: Anti-cancer effects of various ginseng herbal acupuncture were tested by measuring the increase of life span of mice suffering from peritoneal cancer induced by Sarcoma-180, and expression of mRNA manifestation using RT-PCR. The results are as follows: Results: 1. Increase of life span of mice suffering from peritoneal cancer induced by Sarcoma-180 was measured for anti-cancer effects. As a result, 115% increase was shown in the cultivated wild ginseng group, 11.1% increase in the red ginseng group, and no increase was detected in either white ginseng and fresh ginseng groups. 2. Measuring the expression of cytokine mRNA manifestation, expression of $interferon-{\gamma}$ was slightly increased in the cultivated wild ginseng group compared to the control group, but manifestation of interleukin-10 was slightly decreased. 3. For the red ginseng, white ginseng, and fresh ginseng experiment groups II, IL-2, IL-4, $INF-{\gamma}$, and IL -10 all showed increase suggesting possible error occurring during the test process. Conclusion: From the results obtained in this study, we can reason that the ginseng we use may not match the ginseng cited in the texts of the past. Anti-cancer effects of cultivated wild ginseng can be more potent than those of white and fresh ginseng.

Cefodizime has originally been developed for treating infections as antibiotics. However. according to some of recent studies. cefodizime. a third generation cephalosporin. may potentially have the capability of stimulating chemotactic activity of neutrophils and monocytes as well as the strong immuno-modulator. In this study. we studied to learn about the expressive effect of dentritic cells and macrophage. With this background. We have studied to see if cefodizime can be a potential substance inducing an immunological function in dendritic cells and peritoneal macrophages. IL-12 activates NK cell and macrophage, and shows antiviral effect by excreting INF-${\gamma}$. In vitro. total RNAs were extracted from murine dentritic cell at 4, 8, 12, 24hr after the application of 10, 50, 100${\gamma}g$/ml of cefodizime wighout other stimulators. And we analyzed IL-12 mRNA using RT-PCR method. In conclusion. IL-12 mRNA was increased. and the results suggest that cefodizime activate TH1 cell induction, CTL differentiation as well as accelerating the increase of NK. LAK cell.

Purpose : Airways eosinophilia and increased IgE, characteristic features of asthma, result from a predominant Th2 response. In this study, we investigated the effect of CpG oligodeoxynucleotides (ODNs) on the inhibition of airways eosinophilia in mice with established airway inflammation. We also investigated the immunological mechanisms involved. Methods : Groups of BALB/c mice were sensitized intradermally with ovalbumin(OVA). At week 10, airway inflammation was induced by intranasal challenge of the mice with OVA. At week 14, the mice were challenged intranasally again with OVA in the presence and without the presence of CpG ODNs. Mice with saline administration served as negative controls. Bronchoalveolar lavage fluids(BALF) were obtained and eosinophils were counted. Th1 and Th2 cytokines in the spleen cell cultures were measured by ELISA. Serum OVA-specific IgE and IgG2a antibodies were also measured by ELISA. Results : BALF eosinophils were significantly inhibited in the CpG ODNs-treated mice(P<0.01). IgE and IgG2a levels increased significantly in both CpG ODNs-treated and untreated groups as compared to the negative control group; there was, however, no significant difference between the two groups four days after intranasal administration of CpG ODNs. Cytokine analysis revealed decreased production of IL-4, IL-5, and IL-13 and increased production of IL-12 in the CpG ODNs-treated group as compared to the untreated group. Interestingly, $IFN-{\gamma}$ levels were not upregulated in the CpG ODNs-treated group. Conclusion : CpG ODNs vaccination is a potentially useful approach for reversing airways eosinophilia in mice with established airways inflammation.

Background: IFN-$\gamma$ plays an important role in host response to intracellular organisms such as mycobacterium. Human infection with mycobacterium leads to a wide variety of outcomes, ranging from asymptomatic infection to widespread and rapidly fatal disease. Recent reports suggest that alteration of the function of IFN-$\gamma$ caused by a defective IFN-$\gamma$ receptor gene can explain different host response to mycobacterium. In this study, we investigated the role of IFN-$\gamma$ in the development of chronic refractory tuberculosis. Methods: The LPS-induced TNF-$\alpha$ production with or without IFN-$\gamma$ priming was compared by using monocytes taken from recently diagnosed tuberculosis, chronic refractory tuberculosis patients and controls. And the IFN-$\gamma$ receptor was measured by indirect fluorescent antibody technique to know whether change in the priming effect of IFN-$\gamma$ is related to IFN-$\gamma$ receptor deficiency or not. Results: The ratio of TNF-$\alpha$ produced in response to stimulation with INF-$\gamma$ and LPS to LPS alone was $13.5{\pm}7.6$ in controls, $10.8{\pm}6.4$ in recently diagnosed tuberculosis patients and $6.7{\pm}3.9$ in chronic refractory tuberculosis patients. The priming effect of IFN-$\gamma$ significantly decreased in chronic refractory tuberculosis patients compared with that in controls(p=0.002). However, IFN-$\gamma$ receptor deficiency was detected in one of chronic refractory tuberculosis patients. Conclusion: The decrease of the priming effect of IFN-$\gamma$ may play an important role in the development of chronic refractory tuberculosis, and in some patients, this may be related to the IFN-$\gamma$ receptor deficiency.

BACKGROUND : Socheongryong-Tang(小靑龍湯, SCRT), a herbal medicine, has been widely used for the control of respiratory disease in Eastern countries. Recent years SCRT was known as anti-allergic agent. However, its therapeutic mechanisms, especially an inhibitory effect on inflammatory cell infiltration and airway remodeling in allergic asthma are unclear. METHODS : We investigated the effects of SCRT on levels of IL-4, and IFN-g using flow cytometric analysis and infiltration of inflammatory cells in bronchoalveolar lavage fluid(BALF) using cytospin methods in allergen-induced asthma. RESULTS : SCRT decreased levels of IL-4, a Th2-driven cytokine. But INF-g, a Th1-driven cytokine, was not changed. With SCRT treatment, infiltration of inflammatory cells showed reduced tendency. CONCLUSION : In conclusion, we demonstrated that regulation of Th1/Th2 imbalance may be one of mechanism contributed to reduction of inflammatory cell infiltration.

This study was peformed to investigate possible mechanisms underlying possible effect of Coicis Semen composition (CSC) on inflammatory diseases using in vivo model of RA in the mice. Results are summarized as follows. In production of inflammatory cytokines, INF-${\gamma}$ in the spleen and IL-6 in the serum were decreased by CSC treatment. TNF-${\alpha}$ in serum was significantly decreased, IL-4 in the spleen was significantly increased by CSC treatment. In production of rheumatoid factors, IgM and IgG were significantly decreased by CSC treatment. The present data suggest that CSC treatment can improve pathological damage by CIA. So we expect that CSC should be used as a effective drugs for not only rheumatoid arthritis but also another autoimmune disease. Therefore we have to survey continuously in looking for the effective substance and mechanism in the future.

Background : INF-${\gamma}$ plays an important role in the host response to a mycobacterial infection. A complete IFN-${\gamma}$ receptor 1 deficiency is a life threatening condition because it renders patients highly susceptible to a mycobacterial infection. Several mutations in the IFN-${\gamma}$ receptor and STAT1 gene have been identified in the rare mycobacterial infections. These mutations have partial function of the IFN-${\gamma}$ receptor and similar pathologic features to clinical tuberculosis. Materials and Methods : The function of the IFN-${\gamma}$ receptor was evaluated in the patients with clinical tuberculosis. In addition, the DNA coding sequence of the IFNgR1 and STAT1 gene was also analyzed in disseminated tuberculosis patients who might have a defective IFN-${\gamma}$ receptor. Results : The cell surface expression levels of HLA-DR and CD64 in the PMBC after being stimulation with IFN-${\gamma}$ (100IU/ml, 1000IU/ml) were increased in both controls and patients. However, the rate of increase in both groups was similar. The production of TNF-${\alpha}$ in the response to stimulation with LPS was higher in the both groups ($850.7{\pm}687.8$ vs. $836.7{\pm}564.3$ pg/ml). Pretreatment with IFN-${\gamma}$ prior to LPS stimulation resulted in further increase in TNF-${\alpha}$ production between both groups ($2203.5{\pm}242.5$ vs. $2227.5{\pm}560.4$ pg/ml). However, the rate of the increase in TNF-${\alpha}$ production in the both groups was similar. The known mutations in the IFNgR1 and STAT1 coding sequences were not found in the genomic DNA of patients with disseminated tuberculosis. Conclusion : The functional and genetic defects of the IFN-${\gamma}$ receptor were not identified in clinical tuberculosis. This suggests the defective IFN-${\gamma}$ receptor that predispoe patients to a BCG or NTM infection can not alone account for the cases of clinical tuberculosis.
