Background: This present study was conducted to evaluate the anti-inflammatory and immune regulatory effects of Aucklandia lappa Decne (AL). Methods and Results: We measured cytotoxicity, nitric oxide (NO) content, mRNA expression (iNOS, IL-1${\alpha}$, IL-$1{\beta}$, and TNF-${\alpha}$), protein expression (iNOS, COX-2, and $I{\kappa}B$) and phagocytic activity in RAW264.7 cells. Male BALB/c mice were fed 100 mg/kg AL (Aucklandia lappa Decneon 70% ethanol extract) and 250 mg/kg AL for 4 weeks; thereafter, we observed B/T or $CD4^+/CD8^+$ lymphocyte subpopulation change, and expression patterns of $CD4^+$ and $CD8^+$ lymphocytes by immunohistochemical staining in mouse splenocytes and/or thymocytes. To determine the experimental concentration of AL, cell viability was measured by MTT assay and tested at $12.5{\mu}g/m{\ell}$ or less. AL inhibited the levels of NO, lymphokine production (IL-$1{\beta}$, and TNF-${\alpha}$), and mRNA (iNOS, IL-1${\alpha}$, IL-$1{\beta}$, and TNF-${\alpha}$) and protein (iNOS, and COX-2) expression. Additionally, the levels of $I{\kappa}B$, phagocytic activity, and splenic and thymic T lymphocytes, especially $T_H$ and $T_C$ cells were significantly increased in AL administered mice. The immuno-reactive density of $CD4^+$ and $CD8^+$ lymphocytes was stronger in AL groups than in the normal group. AL stimulated NO, iNOS, and COX-2, and regulated IL-1${\alpha}$, IL-$1{\beta}$, TNF-${\alpha}$, and $I{\kappa}B$ in macrophages treated with LPS (lipopolysaccharide). In addition, AL increased the phagocytic activity of macrophages and the immunity of mouse T ($T_H$, and $T_C$) cells. Conclusions: These results suggested that AL might show anti-inflammatory activity via the suppression of various inflammatory markers and immuno-regulatory activity.

Immunological activities of the combined-administration of Ginseng Radix Rubra and Vitis Fructus were examined in C57BL/6 mice. Ginseng Radix Rubra and Vitis Fructus were extracted with distilled water or 40% ethyl alcohol. Ginseng Radix Rubra water extracts (GW), the mixture (1:1) of Ginseng Radix Rubra and Vitis Fructus water extracts [GVW(1:1)], the mixture (1:3) of Ginseng Radix Rubra and Vitis Fructus water extracts [GVW(1:3)], 40% ethyl alcohol extracts of Ginseng Radix Rubra (GE), the mixture (1:1) of Ginseng Radix Rubra and Vitis Fructus 40% ethyl alcohol extracts [GVE(1:1)] and the mixture (1:3) of Ginseng Radix Rubra and Vitis Fructus 40% ethyl alcohol extracts [GVE(1:3)] were administered p.o. once a day for 7 days, respectively. GVW(1:1) and GVW(1:3) decreased the viability of thymocytes increased by GW, but GVE(1:1) and GVE(1:3) increased the viability of thymocytes decreased by GE. GVW(1:1) and GVW(1:3) increased the viability of splenocytes decreased by GW or GE. Also, GVW(1:1) and GVE(1:1) enhanced the population of helper T cell in thymocytes, and GVE(1:1) and GVE(1:3) decreased the population of cytotoxic T cells increased by GE. Furthermore, GVW(1:1), GVW(1:3), GVE(1:1) and GVE(1:3) enhanced the population of $B220^+$ cells decreased by GW or GE, and decreased the population of $Thyl^+$ cells increased by GW or GE, and decreased the population of splenic $CD4^+$ cells increased by GW or GE. In addition, GVW(1:1) and GVW(1:3) decreased the phagocytic activity and the production of nitric oxide in peritoneal macrophages increased by GW, but GVE(1:1) and GVE(1:3) enhanced the phagocytic activity and the production of nitric oxide in peritoneal macrophages decreased by GE. These results suggest that Vitis Fructus has an regulative action on immune response of Ginseng Radix Rubra.

The purpose of this study was to establish an in vitro culture method of tumor-specific T cells, and determine the efficacy of the cultured tumor-specific cytotoxic T-lymphocytes (CTL) as an agent of anti-tumor immunotherapy against a murine lymphoma, TIMI.4. Tumor-specific T-lymphocytes derived from C57BL/6 mice (thy-1.2) immune to TIMI.4 were activated by in vitro stimulation with the irradiated TIMI.4 cells, and expanded by restimulation with TIMI.4 in the presence of the concanavalin A-stimulated rat spleen culture supernatant, and splenic antigen-presenting cells. In vitro restimulation enhanced markedly the proportion of $CD8^+$, a predominant surface marker of CTL and the cytotoxic activity in the cultured immune T cell population. The resulting TIMI.4-specific T cells were adoptively transferred into nude mice. The tumor cells residing in the host after 7 days of adoptive transfer to B6.PL (thy-1.1) mice were quantified by use of an antibody directed to the thy-1.2 allele. The TIMI.4 cells in the recipient nude mice were decreased in a dose-dependent manner. Anti-tumor activity of the TIMI.4-specific T cells was also demonstrated by a survival test, where the tumor-bearing nu/nu mice which received the activated T-cells survived about 30% longer than the control mice which received the tumor cells alone. These suggest that adoptive transfer of TIMI.4-specific T cells could be a candidate for effective therapy of the murine lymphoma.

Purpose : Investigate the effects of Haeganjeon water extract (HGJ) on immobilization-stress or cold-stress in C57BL/6J mice. Methods : Male C57BL/6J 30 mice of weighting 18${\pm}$2g, were divided into sixs groups including the immobilization-stress group(5heads), after immobilization-stress HGJ oral administration(500mg/kg) groups(5heads), cold-stress group(5heads) and after cold-stress HGJ oral administration(500mg/kg) groups(5heads). then we observed changes in the serum histamine and corticosterone level and changes immune system. Results : HGJ decreased the serum level of histamine and corticosterone increased by immobilization-stress or cold-stress. HGJ inhibited the release of histamine from mast cells. In addition, HGJ enhanced the cell viability of thymocytes decreased by immobilization-stress or cold-stress and decreased DNA fragmentation of thymocytes increased by immobilization- stress or cold-stress. Also, HGJ increased the cell viability of splenocytes decreased by cold-stress and decreased DNA fragmentation of splenocytes increased by cold-stress. HGJ decreased the population of thymic CD4+ cells increased by immobolization-stress. HGJ increased the population of B220+ cells decreased by immobilization-stress and decreased the population of Thy1+ cells increased by immobilization-stress. Also, HGJ decreased the population of splenic CD4+ cells increased by immobolization-stress. HGJ enhanced the production of ${\gamma}-interferon$ decreased by immobilization-stress or cold-stress and increased the production of interleukin-4 decreased by immobilization-stress. Furthermore, HGJ enhanced the phagocytic activity decreased by immobilization-stress or cold-stress and enhanced the level of nitric oxide decreased by immobilization-stress or cold-stress. Conclusion : HGJ may be useful for the prevention and treatment of stress via suppression of serum histamine and corticosterone level and enhancement of immune response.

This experimental study was carried out to evaluate the effects of Kimchi intake of Cordyceps sinensis extract (CDSE) supplementation on cytokine-induction and immune response in mice. To study in experiments using male Balb/c mice fed Kimchi and Kimchi of CDSE supplementation (addition of 2% of total Kimchi weight) containing fed experimental diet during 2 weeks. Experimental mice were fed control diet or diet containing freeze-dried Kimchi at the level of 5%(w/w) or 5% freeze-dried Kimchi with 2% CDSE supplementation. The main ingredient of Kimchi was Korean cabbage and fermentation was carried out at $4^{\circ}C$ for three weeks. Freeze-dried 2% CDSE supplementation was added to Kimchi at the beginning of fennentation. In order to investigate the effect of Kimchi intake of CDSE supplementation (5%Kimchi-2%CDSE), the following was performed; body weight, food intake, hematological parameter, serum level of mouse interleukin-4 (mIL-4) and mouse $interferon-{\gamma}$ $(mIFN-{\gamma})$, and, the percentage of CD3+/CD4+, CD3+/CD8+, B220+ in splenic cells. The results of final body weight, and food diet intake of two Kimchi groups were lower than those of the control group (not supplemented experimental diet). The hematology change obtained from the level of WBC (white blood cell) and platelet were not affected by feeding different dietary regiments, but the level of RBC (red blood cells) HB (hemoglobin), and spleen weight of two Kimchi groups were increased significantly than those of the control group. The serum level of IL-4 and $IFN-{\gamma}$ of two Kimchi groups were increased significantly than those of the control group, also enhanced the percentages of the CD3+/CD4+ and CD3+/CD8+ by 5% freeze-dried Kimchi, and 5%Kimchi-2%CDSE group were 43.9 and 60.1%, and 96.0 and 174% than those of the control group, respectively. From these results, it can be concluded that Kimchi itself has an immuno-stimulatory effect and Kimchi contaning 2% CDSE supplementation has the more pronounced effect in vivo system.
