We have investigated the in vitro cytotoxic effect of liposome-encapsulated N-(phospho-nacetyl)-L-aspartic acid (PALA) against C-26 murine colon cancer cells, and have compared it in this regard to free PALA. Three different PALA-containing liposomal formulations using distearoylphosphatidylcholine (DSPC), distearoylphosphatidylglycerol (DSPG), and polyethyle-neglycol-derivatized distearoylphosphatidylethanolamine (PEG-DSPE) were made and their cytotoxicity was measured. In 72 hr continuous exposure experiment with C-26 cells, the 50% growth inhibitory concentration ($IC_50$) of DSPG-PALA liposome formulation was $0.09\mu\$, which showed about 65-fold more potent than unencapsulated free PALA ($5.1\mu\$). Similar degree of increase in cytotoxicity was also observed in 1 hr exposure experiment. However the $IC_50$ of PEG-DSPE-PALA liposome and DSPC-PALA liposome were $10.7\mu\$and $11.8\mu\$respectively, which showed slightly less potent than unencapsulated free PALA. Physical characteristics of PALA-liposomes, such as the size and drug:lipid ratio were also determined. In conclusion, negatively-charged DSPG-PALA liposome showed the highest cytotoxic effect among tested on the C-26 cells in vitro.

Objectives : This experiment was conducted to evaluate the inhibitory effects against lung metastasis and promotion of splenocytes by water-soluble components from five mushrooms extracts (WEFM): Garnoderma frondosa, Corious versicolor, Codyceps militaris, Hericium erinaceus and Lentinula edodes. Methods : Colon 26-L5 carcinoma cells were injected through the tail vein to induce lung metastatic cancer. Changes in weight of lung were observed and cytokine level was analyzed to evaluate immunological changes. Results : Oral administration of WEFM resulted in a significant inhibition of lung metastasis after intravenous injection of colon 26-L5 cells in a dose-dependent manner. There was also a significant increase in T cell and B cell mitogenic stimuli and production of IFN-g by splenocytes stimulated with Con A compared to untreated controls. Conclusion : WEFM may have anti-tumor activities via Th1-type dominant immune responses.

Purpose: This study was designed to investigate the anti-tumor metastasis by immunomodulating effects of extracts of Prunellae Spica. Methods: Antimetastatic experiment was conducted in vivo by using colon 26-M3.1 carcinoma. And we observed cytotoxicity of Prunellae Spica on colon 26-M3.1 carcinoma, L5178Y-R lymphoma cell, hela cell and macrophage. To observe the immnomodulating effects of Prunellae Spica, we estimated IL-6, IL-10, IL-12, TNF-${\alpha}$ from peritoneal macrophages. And we evaluated the activation of NK cell by using anti-asialo-GM1 serum. Results: We found that the administration of Prunellae Spica extracts significantly inhibited tumor metastasis in vivo. In an in vitro cytotoxicity analysis, cell growth are closer to 100% in case of colon 26-M3.1 carcinoma, L5178Y-R lymphoma cell, hela cell at low concentration. In case of macrophage, cell proliferation is closer to 100% less than $62.5{\mu}g/m{\ell}$ of Prunellae Spica extracts. The level of cytokine such as IL-6, IL-10, IL-12 which stimulates Prunellae Spica extracts was increased in dose-dependent manner compared to the control group. TNF-${\alpha}$ is hardly secreted less than $250{\mu}g/m{\ell}$ The depletion of NK cells by anti-asialo GM1 serum partly abolished the inhibitory effect of Prunellae Spica on tumor metastasis. Conclusion: Prunellae Spica appears to have considerable activity on the anti-metastasis by activation the immune system such as macrophage and NK cell.

Hominis placenta (HP) has been used as an agent for promoting physiological function in traditional asian medicine. The present study was peformed to investigate whether HP acupuncture treatment in an experimental tumor mice model inhibit tumor growth through immunomodulatory effects. Mice were inoculated subcutaneously with colon26-L5 cells on the back. Three days after tumor inoculation, HP herbal acupuncture treatment was conducted on BL18 acupoint every other day for three weeks. HP Herbal acupuncture treatment significantly suppressed the primary tumor growth and prolonged survival rate. To evaluate immunomodulatory effect of HP acupuncture, splenocytes proliferation assay, fluorescence-activated cell sorting (FACS) and ELISA for IFN- ${\gamma}$, and IL-4 cytokine level. HP herbal acupuncture enhanced the mitogenic activity of Balb/c whole splenocytes induced by various mitogenic stimuli and increased immune cell population such as T cell, B cell, Th cell, Tc cell and Macrophages. HP herbal acupuncture caused a marked increase of production of Th1 cytokine (IFN- ${\gamma}$ ,) and decrease of production of Th2 cytokine (IL-4). These results indicated that HP herbal acupuncture suppresses tumor growth through a mechanism leading to a Th1 dominant immune state.

BACKGROUND/OBJECTIVES: D. candidum is a traditional Chinese food or medicine widely used in Asia. There has been little research into the anticancer effects of D. candidum, particularly the effects in colon cancer cells. The aim of this study was to investigate the anticancer effects of D. candidum in vitro and in vivo. MATERIALS/METHODS: The in vitro anti-cancer effects on HCT-116 colon cancer cells and in vivo anti-metastatic effects of DCME (Dendrobium canidum methanolic extract) were examined using the experimental methods of MTT assay, DAPI staining, flow cytometry analysis, RT-PCR, and Western blot analysis. RESULTS: At a concentration of 1.0 mg/mL, DCME inhibited the growth of HCT-116 cells by 84%, which was higher than at concentrations of 0.5 and 0.25 mg/mL. Chromatin condensation and formation of apoptotic bodies were observed in cancer cells cultured with DCME as well. In addition, DCME induced significant apoptosis in cancer cells by upregulation of Bax, caspase 9, and caspase 3, and downregulation of Bcl-2. Expression of genes commonly associated with inflammation, NF-${\kappa}B$, iNOS, and COX-2, was significantly downregulated by DCME. DCME also exerted an anti-metastasis effect on cancer cells as demonstrated by decreased expression of MMP genes and increased expression of TIMPs, which was confirmed by the inhibition of induced tumor metastasis in colon 26-M3.1 cells in BALB/c mice. CONCLUSIONS: Our results demonstrated that D. candidum had a potent in vitro anti-cancer effect, induced apoptosis, exhibited anti-inflammatory activities, and exerted in vivo anti-metastatic effects.

Of hot- water extracts prepared from 30 kinds of herbal medicines, Acanthopanax senticosus (75.6% inhibition of control), Atractylodes macrocephale (71.3%), Panax ginseng (70.0%), Glycyrrhiza uralensis (66.3%) and Angelica acutiloba (63.1%) showed the potent tumor metastasis inhibition activity against colon 26-M3.1 lung carcinoma at 2.5 mg/kg body weight, whereas the other extracts had a little activity, except for Pueraria thunbergiana (58.6%) and C. leticulata (54.9%) having the intermediate activity. We also found that Citrus leticulata (1.80-fold of control), A. macrocephale (1.73-fold), A. senticosus and G. uralensis (1.64-fold) enhanced on Peyer's patch cells mediated-hematopoietic response at 100 $\mu\textrm{g}$/mL. In addition, these active herbal medicines were prepared into steam distillates to improve the food rheology as beverage, and to remove the inactive components. Among these steam distillates, A. macrocephale, G. uralensis and A. senticosus showed the significant tumor metastasis inhibition activity at 2.5 mg/kg body weight (58.7%, 50.3% and 41.9%, respectively), and A. macrocephale had the potent activity even at 0,25 mg/kg body weight (49.7%). In treatments of steam distillates with Peyer's patch cells, A. macrocephale and A. senticosus significantly increased the bone marrow cell proliferation even at 10 $\mu\textrm{g}$/mL (1.49- and 1.28-fold of control). Although steam distillates had lower activity than hot-water extracts, herbal medicines, such as A. macrocephale and A. senticosus, showed the high immunostimulating activity in hot-water extracts as well as steam distillates. Therefore, these results assumed the possibility that steam distillates from herbal medicines might be utilized to food industry for beverage.
