Codonopsis lanceolatae have been used as one of the traditional remedies as well as food source. We previously reported that in vitro supplementation of Codonopsis lanceolatae water extracts enhanced the splenocytes proliferation compared to the control group. This study, the combined immunomodulative effect of water extract Codonopsis lanceolatae was Seven to eight weeks old mice(balb/c) was fed ad libitum on chow diet and water extract of Codonopsis lanceolatae was orally administrated every other day for four weeks at two different concentrations(50 and 500 mg/kg B.W.). The production of cytokine(IL-2, IL-10 and IFN-${\gamma}$), secreted by macrophages stimulated with LPS or not, were detected by ELISA assay using the cytokine kit. The result of ex vivo study showed that the IL-2, IL-10 and IFN-${\gamma}$ was detected at 500 mg/kg B.W. supplementation group with LPS stimulation in all cases. Also, ratio of IFN-${\gamma}$, IL-10 was the range of 3${\sim}$7 with mitogen stimulation such as Con A and LPS. In conclusion, this study suggests that Codonopsis lanceolatae extracts may enhance the immune function by regulating the cytokine(IL-2, IL-10 and IFN-${\gamma}$) prodution capacity by activated macrophages in mice.

Background and Objective : Asthma is a chronic inflammatory disease at the mucosa and is associated with excess production of Th2 cytokine and eosinophil accumulation in lung.Gamchomahwang-tangextract(GME) is one of the well known prescription used in oriental medicine for treating asthma. This study was designed to compare the anti-asthmatic effect of GME according to the ratio of 2 compounds.Methods : To examine the effects of GME on asthma, mice were sensitized with 100 ㎍ of OVA and 1 ㎎ of aluminum potassium sulfate(Alum; Sigma) intraperitoneally on day 1 and 15. From day 22, mice were challenged on 3 consecutive days with 5% OVA. The anti-asthmatic effects of GME were evaluated by enhanced pause(Penh), bronchoalveolar lavage fluids (BALF), inflammatory cytokine production and genes expression, serum IgE production. and histological change in lung tissue. GMEⅠ consists of ES and GU in the proportion 2:1(300 ㎎/㎏ group), GMEⅡ consist of ES and GU in the proprtion 4:1(300 ㎎/㎏ group).Results : GMEⅠ,Ⅱ generally inhibited lung inflammation, inflammatory cells infiltration and cytokine production and gene expression such as IL-4, IL-5 and IL-13 in BALF and serum IgE level. GMEⅡ significantly reduced the cytokine production and gene expression such as IL-4, IL-5 and IL-13 in BALF and GMEⅠ decreased cytokine production of IL-4, IL-13 in BALF and gene expression of IL-4, IL-5 in Lung. GMEⅡ potently inhibited the development of Penh and also reduced the number of eosinophil during OVA-induced AHR(airway hyper-reactivity). Overall the results show that GMEⅡ has more effect on inhibiting production, gene expression of cytokine, serum IgE level and development of Penh than GMEⅠ. Consequently, GMEⅡ might be more effective than GMEⅠ at inhibiting allergic asthma on the OVA-induced mice model.Conclusion : These results indicate that GME has a deep inhibitory effects on airway inflammation and hyperresponsiveness in mice model of asthma and that suppression of IL-4, IL-5, IL-13 expression and decrease of IL-4, IL-5, IL-13 production in BALF might contribute this effect. Hence, the results indicate that GME might be useful herbal medicine of allergic asthma. As a result, GMEⅡ mght be superior to GMEⅠ in the aspect of anti-asthmatic effect on the OVA-induced mice model.

The nutritional status of host has a profound effect on immune response and its ability to defend aganinst invading pathogen. Almost all nutrient dificiencies impaired host defence, and more than recommended levels of certain nutrient enhance immune response beyond that observed with 'adequate'. But high-fat diets have been associated with various types of immune dysfunction in experimental animal models and humans. Also, high linoleic acid suppressed immune function and growth and metastasis of tumor than saturated fatty acids. The present review focused on the effect of dietary lipid on immune fuction, cytokine production and clinical conditions like infection, autoimmune disease and cancer.

In 1998, Osada and co-workers isolated 140 mg of a novel cytokine modulator from 18 L of the culture broth of Streptomyces RK95- 31 isolated from a soil sample in Hiroshima Prefecture. This new immunosuppressant was named (-)-cytoxazone and its absolute configuration was determined on the basis of its NMR, CD and X -ray analysis. It interferes with cytokine IL4, IL10 and IgG production by selective inhibition of the signaling pathway of Th2 cells, but not Thl cells. Inhibitors of Th2-dependent cytokine production have potential as potent chemotherapeutic agents in the field of immunotherapy. The (-)-cytoxazone is different from known immunomodulators such as FK 506 and rapamycin in respect of structure and biological activity. As such cytoxazone should be a useful tool for understanding signaling pathways in Th2 cells, the synthesis of (-)-cytoxazone is of interest for the development of new cytokine modulators.

We investigated that the immunomodulating activity of BL18 (Ganshu) acupuncture on the experimental liver metastasis model of mice. NA (non-acupoint)- and BL18-treatment enhanced the mitogenic activity of BALB/c whole splenocytes induced by various mitogenic stimuli. Acupuncture treatment tended to increase splenocytes differentiation even though did not show significance. Acupuncture treatment caused a marked increase of production of Th1 cytokine (IFN-${\gamma}$) and Th2 cytokine (IL-4) by splenocytes and IL-12 and IFN-Y by macrophages. The increase of cytokine production on BL18-treated group was more pronounced compared to NA-treated group. The liver weight of NA- and BL18-treated group decreased compared to tumor group, but did not showed significant differences.

Objectives: The object of this study was to identify the anti-inflammatory effects of Patrinia scabiosaefolia aqueous extract (PSE). Methods: RAW 264.7 cells were pre-treated with PSE and then incubated with or without lipopolysaccharide (LPS). Cell viability, production of nitric oxide (NO), secretion of pro-inflammatory cytokine, activation of mitogen-activated protein kinases (MAPKs) and nuclear factor-kappa B (NF-${\kappa}B$) were measured. In addition, we observed mice survival rate after LPS and their cytokine levels of serum. We also observed inflammatory and hemorrhagic change on the histological sections of the liver. Results: PSE inhibited LPS-induced NO production, interleukin (IL)-6 secretion, c-Jun NH2-terminal kinase (JNK) and NF-${\kappa}B$ activation. In addition, PSE reduced the death rate of LPS-induced mice and IL-6 production on the serum of mice. PSE inhibited inflammation and hemorrhage on liver tissue as well. Conclusions: The results suggest that PSE have anti-inflammatory effects by inhibited NF-${\kappa}B$ and JNK activation, IL-6 secretion, and NO production. So PSE may be effective treatment for the inflammatory disease.

Sorghum bicolor L. Moench(Sorghum, Su-Su) is a major cereal food crop used in many parts of the world. It is used as a human food resource and folk medicines in Asia and Africa. The stem of sorghum has been used as a digestive aid and an anti-diarrheal agent. Sorghum hybrids contain high levels of diverse phenolic compounds that may provide health benefits. High levels of polyflavanols, anthocyanins, phenolic acids, and other antioxidant compounds have been reported in sorghums, which have also been shown to possess various biological activities such as anti-mutagenic, anti-carcinogenic, and HMG-CoA reductase inhibitory activities. In an in vitro experiment, we examined mice splenocyte proliferation and production of three types of cytokine($IL-1{\beta},\;IL-6,\;TNF-{\alpha}$) by peritoneal macrophages cultured with ethanol and water extracts of Sorghum bicolor L. Moench. A single cell suspension of splenocytes was prepared and the cell proliferation of the splenocytes was examined by MTT assay. The splenocyte proliferation was increased when water extracts of Sorghum bicolor L. Moench were used as supplements in all concentrations investigated. The production of cytokine($IL-1{\beta},\;IL-6,\;TNF-{\alpha}$) by activated peritoneal macrophage was detected by ELISA using the cytokine kit. $IL-1{\beta},\;IL-6,\;and\;TNF-{\alpha}$ production by activated macrophages were increased by supplementation with Sorghum bicolor L. Moench water extracts. This study suggests that supplementation of with Sorghum bicolor L. Moench water extracts may enhance immune function by regulating the splenocyte proliferation and enhancing the cytokine production by activated macrophages in vitro.
