Objective : The present experiments were designed to study on the immune-enhancing effect of Mountain grown ginseng, Mountain cultivated ginseng, and Panax ginseng Method : In order to compare the immune-enhancing effect of moutain grown ginseng, moutain cultivated ginseng and Panax ginseng, the study was done through the forced swimming test (FST), measurement of T helper Th1, Th2 cytokines and fatigue related factors. Result : Moutain grown ginseng and panax ginseng decreased the immobility time in the FST compared to the control. Glucose, blood urea nitrogen (BUN), creatinine, lactate dehydrogenase (LDH) and Total-protein (T-protein) in serum were investigated. The serum achieved from ginseng administered mouse showed higher BUN, T-protein than the control. moutain grown ginseng administered group showed lower LDH than the control group. moutain grown ginseng administered mouse showed higher glucose than the control. Creatinine was same in either experimental or control group. Ginseng-induced cytokine production in human T-cell line, MOLT-4 cells and mouse peritoneal macrophages were compared. Moutain cultivated ginseng (10-4 dilution) and panax ginseng (10-3 dilution) were increased the interferon $IFN-{\gamma}$ production compared with media control (about 1.6-fold P<0.05) at 48 h. Moutain grown ginseng (10-4 dilution) was increased the $IFN-{\gamma}$ and interleukin IL-4 production compared with media control (about l.4-fold for $IFN-{\gamma}$ and 1.6-fold for IL-4 P<0.05) at 48 h. Moutain grown ginseng (10-3 dilution) and moutain cultivated ginseng (10-4 dilution) were increased the turmor necrosis factor $TNF-{\alpha}$ production compared with $rIFN-{\gamma}$ treated cells (about 1.9-fold for $TNF-{\alpha}$ P<0.05), respectively. Moutain cultivated ginseng (10-3 dilution) was increased the IL-12 production compared with $rIFN-{\gamma}$ treated cell (about 1.7-fold for IL-12 P<0.05). Conclusion : These data suggest that three different three kinds of ginseng act on immune responses in different aspects.

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.

When the inhibitory effect of ginsenoside (G) Re isolated from ginseng and its metabolites G-Rg1, G-F1, G-Rh1 and protopanaxatriol in mouse ear skin psoriasis stimulated by oxazolone was investigated, G-Re and its metabolites suppressed mouse ear swelling stimulated by oxazolone. Among these agents tested, G-Rh1 most potently suppressed ear swelling as well as mRNA expression of COX-2 and proinflammatory cytokines $IL-1{\beta},\;TNF-{\alpha}$ and $interferon-{\gamma}$. These findings suggest that G-Rh1 may improve chronic dermatitis and psoriasis.

The enhancement of immunity for atopic dermatitis with application of eicosapentaenoic acid (EPA)-loaded liposome was evaluated on NC/Nga mice. The EPA-loaded liposome was coated with thiol-chitosan. The liposomes were characterized with transmission electron microscopy (TEM), surface zeta potential & particle size analyzer (Zeta-PSA) and differential scanning calorimetry (DSC). The loading efficiency of EPA in the liposome was about 4.7%. The particle size of the EPA-Ioaded liposome was about 230 nm. The values of Immunoglobulin E (IgE), interleukin-4 (IL-4), and tumor necrosis factor-$\alpha$ (TNF-$\alpha$) were reduced significantly with application of the EPA-loaded liposome. The interferon-$\gamma$ (IFN-$\gamma$) value was increased with the application effect. It is concluded that EPA loaded liposome have immunity advancing effects in mouse model of atopic dermatitis.

This study is aimed to investigate the anti-inflammatory effect of Euphorbiae kansui radix methanol extract (ERE) in lipopolysaccharide(LPS)-stimulated mouse peritoneal macrophages. Peritoneal macrophages were obtained from thioglycollate-injected Balb/c mice. Cells were stimulated with LPS or LPS plus interferon-gamma (IFN-${\gamma}$) in the presence of ERE and various inflammatory markers were assayed. Finally, LPS-induced signaling molecules were measured. ERE up to $400{\mu}g/m{\ell}$, was not cytotoxic to ERE inhibited LPS/IFN-${\gamma}$-induced nitric oxide (NO), inducible NO synthase. ERE also reduced the levels of cyclooxygenase-2 and the proinflammatory cytokines such as tumor necrosis factor-${\alpha}$, interleukin(IL)-6 and IL-12. The inhibitory effect of ERE on LPS-induced $I{\kappa}B{\alpha}$ degradation was weak but phosphorylation of JNK, p38 and ERK1/2 was strongly suppressed. Our data indicated that the anti-inflammatory effect of ERE in LPS-stimulated macrophages was partly mediated by its inhibition of JNK, p38 and ERK1/2.

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.

Interleukin (IL)-18, a member of the family of IL-l cytokine, is one of the principal inducers of $interferon-{\gamma}(IFN-{\gamma})$ in T lymphocytes and natural killer cells. The objective of the present study was to evaluate the effect of IL-18 on the expression of chemokine IP-10 (CXCL-10) mRNA in mouse peritoneal macrophages. IL-18 had very weak direct effect or synergistic effect with IL-12 on the expression of IP-10 mRNA in C57BL/6 mouse peritoneal macrophages. However, IL-18 pretreatment was found to playa cooperative role in the expression of lipopolysaccharide (LPS)-induced IP-10 mRNA. For the expression of LPS-induced IP-10 mRNA, the synergistic effect was detected after 16 h of IL-18 pretreatment prior to LPS stimulation. The expression level of CD14 in cells stimulated with LPS was not changed by IL-18 pretreatment, and the level of $IFN-{\gamma}$ production during IL-18 pretreatment plus LPS stimulation was barely discernible ($0.36{\pm}0.31pg/ml$). Namely, the synergistic effect of IL-18 pretreatment was not related to a change of LPS receptor, CD14 expression, and the production of $IFN-{\gamma}$ by the interaction between IL-18 and LPS. The synergistic effect of IL-18 pretreatment on the expression of LPS-induced IP-10 was related to not NF-kB but AP-1 activation, and associated with the extracellular signal-regulated kinase (ERK) pathway, one of the mitogen-activated protein kinase signaling pathways. These results provide useful information that may elucidate the mechanisms underlying the effect of IL-18 on the expression of IP-10 mRNA.
