This study was performed to compare anticancer and immune activities between natural Artemisia capillaris Thunb. extract and tissue cultured plant extract (hairy root, in vitro culture, callus). The inhibitory effect of cancer cell growth, human B cell growth and productivity of cytokines were examined. Furthermore, HPLC analysis was performed to confirm the components. The anticancer activities increased by more than 55% with the cultured callus of Artemisia capillaris T. for four cancer cell lines(Lung carcunoma, Stomach adenocarcinoma, Hepatocillular carcinoma, Breast adenocarcinoma), showing higher effect than natural Artemisia capillaris T. The extracts from hairy root and in vitro culture of Artemisia capillaris T. significantly increased the immune B cell growth. The immune B cell growth effect of natural Artemisia capillaris T. was higher than that of the tissue culture plants such as hairy root, in vitro culture and callus. Both natural and tissue cultured plants showed similar effects on cytokine secretion. The similar peak size was observed between natural Artemisia capillaris T. and cultured callus in HPLC analysis. As a results, the biological activities were not observed the difference between natural Artemisia capillaris T. and cultured callus. Thus, the cultured callus will be altered natural Artemisia capillaris T. in the environmental side and the resources preservative side

Inflammation is a complex process involving a variety of immune cells, which defend the body from harmful stimuli. However, pro-inflammatory cytokines and inflammatory mediators can also exacerbate diseases such as cancer. Onion peel contains several phenolic compounds, including quercetin at an amount 20 times greater in peel than edible flesh. Therefore, in this study, the anti-inflammatory effects of onion peel ethanol extract (OPEE) were investigated lipopolysaccharide-induced inflammatory response. In our results, NO production decreased in a dose-dependent manner. Secretion of IL-6, $TNF-{\alpha}$, and $IL-1{\beta}$ was suppressed by 44%, 53%, and 60% respectively, at $100{\mu}g/mL$. Moreover, OPEE also suppressed expression of COX-2, iNOS, $NF-{\kappa}B$, and MAPKs in a dose-dependent manner. Formation of mice ear edema was reduced at the highest dose tested compared to the control, and reduction of ear thickness was observed in the histological analysis as well. In the acute toxicity test, no morality was observed in mice administered 5,000 mg/kg body weight of OPEE over a 2-week observation period. These results suggest that OPEE may have significant effects on inflammatory factors and be a potential anti-inflammatory material.

The low quality fresh ginseng was fermented by Phelinus linteus or Hericium erinaceum mycelium. This fermented ginseng was extracted by water at $100^{\circ}C$ or water with ultrasonification at $60^{\circ}C$. Total phenolic compounds was improved by ultrasonification extraction process, compare to conventional water extraction. All extracts enhanced the growth of human B and T cells, showing 2.68 times and 3.43 times higher, respectively, than the control. The secretion of TNF-$\alpha$ and IL-6 from human immune cells was enhanced as $3.53{\times}10^{-4}\;pg/cell$, $3.40{\times}10^{-4}\;pg/cell$ by adding H. erinaceum mycelium fermented ginseng. H. erinaceum mycelium fermented ginseng yielded higher nitric oxide production from macrophage than Lipopolysaccharides (LPS). The cytotoxicity on human normal kidney cell (HEK293) was as low as 20.5% in adding the maximum concentration of $1.0\;mg/m{\ell}$ of fermented ginseng. Generally, the extracts from ultrasonification extraction process showed 10% lower toxicity than that by conventional process. H. erinaceum mycelium fermented ginseng had the highest anticancer activity on human lung cancer and stomach cancer cells as 69.33% and 75.32%, respectively at $1.0\;mg/m{\ell}$. It can be concluded that, in general, H. erinaceum mycelium fermented ginseng has relatively better immune and anticancer activities than P. linteus fermented ginseng. Expecially, the extracts treated with ultrasonification had higher activities than that from conventional extraction process.

LP-BM5 murine leukemia retrovirus induces the immune dysfunction by imbalanced secretion of Th1 and Th2 cytokines in the murine AIDS model. In the present study, it was investigated whether pycnogenol (Pyc) administration could deactivate $NF-{\kappa}B$ to regulate the gene expression of Th1 and Th2 cytokines in C57BL/6 mice with murine AIDS. Treatment with Pyc for 12 weeks significantly inhibited the loss of body weight and enlargement of spleen and lymph node usually seen with AIDS. Moreover, Pyc increased the plasma level of Th1 cytokines, IL-2 and $IFN-{\gamma}$, while reducing the plasma level of Th2 cytokines, IL-6, IL-10, and $TNF-{\alpha}$. In primary culture of splenocytes, mRNA expression of Th2 cytokines was suppressed, but that of Th1 cytokines was not affected. The LP-BM5 retrovirus infection stimulated the cytoplasmic activation of $NF-{\kappa}B$ and nuclear translocation of $I-{\kappa}B$, whereas Pyc administration significantly reduced $NF-{\kappa}B$ activation and $I-{\kappa}B$ degradation. These results suggested that the inhibitory effect of Pyc on Th2 cytokines in mice with murine AIDS was dependent on suppression of the $NF-{\kappa}B$ signaling pathway and was not dependent on $INF-{\gamma}$ level, which regulates Th2 cytokines.

The methanolic (MeOH) extract of A. fruticosa bark, which showed immune-regulatory activities, was separated to purify an active compared by means of a multi-stage column chromatography. This resulted in the isolation and characterization of an isoflavone glycoside named 4', $6-Dimethoxyisoflavone-7-O-{\beta}-D-glucopyranoside$. Immuno-regulatory activities of the crude extract of Amorpha fruticosa LINNE bark were compared with that of an isoflavone glycoside (4', $6-dimethoxyisoflavone-7-O-{\beta}-D-glucopyranoside$). The crude methanolic extract of A. fruticosa and purified single compound showed 16% of relatively low cytotoxicity at a maximum concentration of 1.0 g/L in cultivated normal human lung cell line (HEL299). Cell growth of human T cells was increased up to 15%, 0.5 g/L of the crude extract added group. This was higher than a single compound added one. On the other hand, specific production rates of IL-6 and $TNF-{\alpha}$ from T cell were higher in the purified compound treat group ($0.82{\times}10^{-4}\;pg/cell$ and $1.08{\times}10^{-4}\;pg/cell$, respectively), compared to 0.5 g/L of the crude extract added group ($0.65{\times}10^{-4}\;pg/cell$ and $0.84{\times}10^{-4}\;pg/cell$, respectively). In addition, the growth of NK-92MI cells incubated with the crude extract was higher up to 56% over the cells grown with a single compound (0.5 g/L). In overall, the crude extract showed relatively higher immuno-regulatory activities compared with a single compound, probably due to the synergic effect given by other substances existed in the crude extract. Even though the siolated compound stimulated higher secretion of cytokines from human T cells.

Immune activities of two different extracts of Kadsura japonica Dunal. by typical extraction processes using water and ethanol at 60 $^{\circ}$C and 100 $^{\circ}$C were compared to them by ultrasofication system and through traditional fermemtation process. The fermented broth Kadsura japonica Dunal. definitely improved the growth of human B and T cell up to 30% and 22%, respectively, compared to the control. The secretion of TNF-${\alpha}$ and IL-60 was also enhanced by the addition of the fermented broth, up to 35%. NK cell activation was significantly improved up to 1.4 times higher than the case of adding other extracts. It was also found that this broth could yield higher nitric oxide production from macrophage than Lipopolysaccharides (LPS). It can be concluded that Kadsura japonica has immune activities and, in general, the culture broth from a conventional fermentation has higher immune activities, possibly by yielding immuno-modulatory compounds, not existed in typcial extraction systems as the result of HPLC analysis.

Sodium butyrate (SB) has various metabolic actions. However, its effect on dipeptidyl peptidase 4 (DPP-4) needs to be studied further. We aimed to evaluate the metabolic actions of SB, considering its physiologically relevant concentration. We evaluated the effect of SB on regulation of DPP-4 and its other metabolic actions, both in vitro (HepG2 cells and mouse mesangial cells) and in vivo (high fat diet [HFD]-induced obese mice). Ten-week HFD-induced obese C57BL/6J mice were subjected to SB treatment by adding SB to HFD which was maintained for an additional 16 weeks. In HepG2 cells, SB suppressed DPP-4 activity and expression at sub-molar concentrations, whereas it increased DPP-4 activity at a concentration of $1,000{\mu}M$. In HFD-induced obese mice, SB decreased blood glucose, serum levels of insulin and $IL-1{\beta}$, and DPP-4 activity, and suppressed the increase in body weight. On the contrary, various tissues including liver, kidney, and peripheral blood cells showed variable responses of DPP-4 to SB. Especially in the kidney, although DPP-4 activity was decreased by SB in HFD-induced obese mice, it caused an increase in mRNA expression of $TNF-{\alpha}$, IL-6, and $IL-1{\beta}$. The pro-inflammatory actions of SB in the kidney of HFD-induced obese mice were recapitulated by cultured mesangial cell experiments, in which SB stimulated the secretion of several cytokines from cells. Our results showed that SB has differential actions according to its treatment dose and the type of cells and tissues. Thus, further studies are required to evaluate its therapeutic relevance in metabolic diseases including diabetes and obesity.
