  • The purpose of this research was to investigate the effect of Cheongsimondam-tang(CSODT) on the activity of immune cell and anti-carcinogenic effect of mouse leukemia cell. The addition of CSODT(1 ㎍/ml) enhanced the proliferation of cultured-splenocytes and thymocytes. And also administration of CSODT(500 ㎍/kg) accelerated subpopulation of splenic and thymic T lymphocytes especially CD4/sup +/-T/sub H/ cells in BALB/c mice. CSODT treatment decreased cell proliferation and increased apoptotic cell death of cultured-L1210 leukemia cells, and induced apoptosis in addition to decreased mitochondrial transmembrane potential (ΔΨm) of transplanted-L1210 cells in vivo. These results suggest that CSODT have a cellular immuno-regulatory effect and anti-cancer property action.

  • We measured physiological functionalities, including antihypertensive angiotensin I-converting enzyme inhibitory activity and immun-stimulating ${\beta}$-glucan content for sixty kinds of Makgeolli that is commercially available from the market. As a result, we selected R-12 commercial raw Makgeolli, with a high content of immuno-stimulating ${\beta}$-glucan, and R-14 commercial raw Makgeolli, exhibiting high antihypertensive activity. Due to the similarities in their overall physicochemical properties and raw materials used for fermentation, we compared the microbial flora in order to investigate the reason for the differences in their functionalities. Nested PCR and denaturing gradient gel electrophoresis for yeasts and bacteria were performed for analysis of microbial diversity of two different kinds of Makgeolli (i.e., R-12, R-14), which showed immuno-stimulating ${\beta}$-glucan content and exhibited a very high level of antihypertensive activity, respectively. Analysis of the 18S rDNA amplicon revealed a major presence of the yeast strain Pichia burtonii in every Makgeolli sample. Analysis of the 16S rDNA amplicon revealed a predominance of lactic acid bacteria, and the most frequent lactic acid bacteria were Lactobacillus ingluviei, L. fermentum, and L. harbinensis, and Lactobacillus sp. Among these, L. harbinensis was detected only in R-12 and L. ingluviei was found only in R-14. Different functionalities from the individual commercially available Makgeolli may be attributed to actions of different microbial flora during fermentation.

  • Purpose: This research aimed to study the effect of FAE(Ferment Artemisiae Argyi Folium and Epimedii Herba) on the mouse macrophage cell activity. Methods: Effect of FAE, which was fermented by Sacchromyces cerevisiae STV89, on cell viability, amount of $H_2O_2$ within cells, amount of NO was measured and compaperd by using mouse macrophage cells. Results: 1. Result of MTT assay conducted to observe the effect of FAE on the survival rate of mouse macrophage cells illustrated that, when FAE was proccessed for each concentration, there was no significant decrease of the survival rate. 2. FAE increased the amount of $H_2O_2$ within macrophage cells and increased inhibition of amount of $H_2O_2$ in macrophage induced by LPS. 3. FAE inhibited amount of NO in macrophage cells, and significantly inhibited increase of amount of NO in mcacrophage induced by LPS. Conclusion: FAE produced by Artemisiae Argyi Folium and Epimedii Herba did not induce the decrease of macrophage cell survival rate, increased amount of $H_2O_2$ within cells, and reduced amount of NO. FAE significantly increase by LPS, reduced the increase of amount of NO in macrophage induced by LPS. These results signify FAE has significant effect on immuno modulating activity of macrophage.

  • To elucidate the novel biological function of Korean traditional vinegars, crude polysaccharides were isolated from vinegars manufactured at home and abroad, and their chemical properties and immuno-stimulating activities were examined. Three kinds of polysaccharides from Korean brown rice vinegar (KBV-0), Japanese brown rice vinegar (JBV-0) and Korean persimmon vinegar (KPV-0) showed higher immuno-stimulating activity. Component sugar analysis indicated that KBV-0 and JBV-0 mainly consisted of mannan, whereas KPV-0 existed as pectic materials. Three polysaccharides did not show any cytotoxicity to RAW 264.7 cell, whereas RAW 264.7 cells stimulated with KBV-0, JBV-0 and KPV-0 showed enhanced production of various cytokines such as IL-6, IL-12 and TNF-${\alpha}$ in dose-dependent manners. However, the activity of KPV-0 was more potent than that of KBV-0 and JBV-0. Also, only KPV-0 augmented FcR II expression related with phagocytosis of macrophages. The results suggest among the tested vinegars, that the Korean persimmon vinegar has the most potent immune-stimulating activity, and it could possibly serve as industrial applications as functional materials.

  • In this study, we examined immuno-modulatory activities of crude polysaccharides from wild ginseng adventitious roots (WGAR). The crude polysaccharide (WGAR-CP) was isolated from WGAR by hot water extraction, ethanol precipitation, and dialysis. The major constituents in WGAR-CP were neutral sugar (64.77%), and uronic acid (34.32%). WGAR-CP demonstrated anti-complementary activity dose-dependently. The immuno-modulatory effects of WGAR-CP were also analyzed by measuring nitric oxide and cytokines in the supernatants of mouse peritoneal macrophages. Mouse peritoneal macrophages stimulated with WGAR-CP produced nitric oxide and various cytokines such as interleukin (IL)-6 and IL-12 in a dose-dependent manner. In conclusion, WGAR-CP may have immuno-modulatory activities by activating a complementary system and macrophages, which produces cytokines.

  • Polysaccharides isolated from Korean black raspberry wine were examined for their chemical properties and immuno-modulating activities. The molecular mass of RB-1b-I, the main polysaccharide in black raspberry wine, was estimated as 180 kDa and it contained a significant proportion of mannose (76.8%) and 4 different minor component sugars such as galactose (15.8%), arabinose (3.8%), glucose (2.6%) and rhamnose (1.2%). This indicated that RB-1b-I was mainly present as a mannan, which had originated from the cell walls of fermenting yeasts. On the other hand, RB-1b-I induced high levels of macrophage activation as well as mitogenicity regarding murine splenocytes in vitro. The intravenous administration of RB-1b-I significantly augmented NK cytotoxicity against YAC-1 tumor cells. RB-1b-I also showed potent anti-complementary activity in a dose-dependent manner via both alternative and classical pathways. Results indicated that Korean black raspberry wine contains peculiar polysaccharides which provide beneficial immuno-stimulating activities for human health.

  • The immune system plays an important role in maintaining and protecting human health. In the present study, comparison of immuno-modulatory activities between polysaccharides (SFP) and ethanol (SFE) extracts separated from Sargassum fulvellum in macrophages and murine splenocytes were investigated. Immuno-modulatory activities of macrophages were estimated based on cell proliferation, nitric oxide (NO), inducible NO synthase (iNOS), and cytokine production in RAW 264.7 macrophage cells, and lipopolysaccharide was used as a positive control. SFP and SFE treatment did not affect cytotoxicity in RAW 264.7 macrophage cells, and SFP treatment significantly increased NO and cytokine production ($TNF-{\alpha}$, IL-6, and $IL-1{\beta}$), whereas SFE did not contribute to the increase in NO and cytokine production. In the case of splenocytes, SFP treatment increased splenocyte proliferation and also highly increased production of Th-1 type cytokines (IL-2 and $IFN-{\gamma}$) than those of SFE. Through this study, we confirmed that immuno-modulatory activities of Sargassum fulvellum may be due to polysaccharide extracts and this can be a potential nutraceutical.

  • This study compared the immuno-modulatory effects of ethanol extracts (A. muricata L. ethanol extracts, ALE) and crude polysaccharide fraction (A. muricata L. crude polysaccharide fraction, ALP) from Annona muricata L. in macrophages. Immuno-modulatory activity was determined by assessing cell viability, nitric oxide (NO) production, inducible NO synthase (iNOS) expression and cytokine production in RAW 264.7 a macrophage cell line. Both ALE and ALP treatment did not affect cytotoxicity, and ALP treatment significantly increased NO production. Additionally, cytokine production [tumor necrosis factor ($TNF-{\alpha}$; $2909.04{\pm}4.1pg/mL$), interleukin (IL)-6; $662.84{\pm}5.3pg/mL$, and $IL-1{\beta}$; $852.37{\pm}2.2pg/mL$), was highly increased in the ALP ($250{\mu}g/mL$) treated group compared to the ALE ($250{\mu}g/mL$) treated group ($TNF-{\alpha}$; $1564.50{\pm}6.1pg/mL$, IL-6; $517.24{\pm}4.1pg/mL$ and $IL-1{\beta}$; $237.23{\pm}1.8pg/mL$). Moreover, ALP treatment considerably increased the expression of mitogen-activated protein kinase (MAPKs) and nuclear $factor-{\kappa}B$ ($NF-{\kappa}B$) in the macrophages. Therefore, ALP can induce macrophage activation through MAPK and $NF-{\kappa}B$ signaling and this can be a potential candidate for development of nutraceuticals.
