${\beta}$-(1,3)-D-Glucans have been known to exhibit antitumor and antimicrobial activities. The presence of dectin-1,${\alpha}$, ${\beta}$-glucan receptor of dendritic cell, on macrophage has been controvertial. RT-PCR analysis led to the detection of dectin-1${\alpha}$ and ${\beta}$ in murine macrophage Raw264.7 cell line. Among the various organs of mouse, dectin-1${\alpha}$ and ${\beta}$ were detected in the thymus, lung, spleen, stomach and intestine. To analyze gene expression modulated by ${\beta}$-glucan treated murine Raw264.7 macrophage, total mRNA was applied to cDNA microarray to interrogate the expression of 7,000 known genes. cDNA chip analysis showed that ${\beta}$-glucan of P. osteatus increased gene expressions of immunomodulating genes, membrane antigenic proteins, chemokine ligands, complements, cytokines, various kinases, lectin associated genes and oncogenes in Raw 264.7 cell line. When treated with ${\beta}$-glucan of P. osteatus and LPS, induction of gene expression of TNF-${\alpha}$ and IFN-R1 was confirmed by RT-PCR analysis. Induction of TNF-R type II expression was confirmed by FACS analysis. IL-6 expression was abolished by EDTA in ${\beta}$-glucan and LPS treated Raw264.7 cell line, indicating that ${\beta}$-glucan binds to dectin-l in a Ca$\^$＋＋/ -dependent manner. To increase antitumor efficacy of ${\beta}$-glucan, ginsenoside Rh2 (GRh2) was co-treated with ${\beta}$-glucan in vivo and in vitro tests. IC$\sub$50/ values of GRh2 were 20 and 25 $\mu\textrm{g}$/$m\ell$ in SNU-1 and B16 melanoma F10 cell line, respectively. Co-treatment with ${\beta}$-glucan and GRh2 showed synergistic antitumor activity with cisplatin and mitomycin C both in vitro and in vivo. Single or co-treatment with ${\beta}$-glucan and GRh2 increased tumor bearing mouse life span. Co-treatment with ${\beta}$-glucan and GRh2 showed more increased life span with mitomycin C than that with cisplatin. Antitumor activities were 67% and 72 % by co-injection with ${\beta}$-glucan and GRh2 in the absence or presence of mitomycin C, respectively.

Although BinSo-San(BSS), a mixed herbal formula consisted of 11 types of medicinal herbs and have been used as anti-inflammatory agent, In the present study, the acute toxicity (single oral dose toxicity) of lyophilized BSS aqueous extracts was monitored in male and female mice after oral administration according to Korea Food and Drug Administration (KFDA) Guidelines (2005-60, 2005). In order to observe the 50% lethal dose ($LD_{50}$), approximate lethal dosage (ALD), maximum tolerance dosage (MTD) and target organs, test articles were once orally administered to female and male ICR mice at dose levels of 2000, 1000, 500, 250 and 0 (control) mg/kg (body wt.) according to the recommendation of KFDA Guidelines (2005-60, 2005). The mortality and changes on body weight, clinical signs and gross observation were monitored during 14 days after dosing according to KFDA Guidelines (2005-60, 2005) with organ weight and histopathology of 12 types of principle organs. We could not find any mortality, clinical signs and changes in the body weights except for dose-independent increases of body weight and gains restricted in 1000 mg/kg of BSS extracts-dosing female group. Hypertrophic changes of lymphoid organs.thymus, spleen and popliteal lymph nodes were detectedat postmortem observation with BSS extracts dose-dependent increases of lymphoid organ weights, and hyperplasia of lymphoid cells in these all three lymphoid organs at histopathological observations. These changes are considered as results of pharmacological effects of BSS extracts or their components, immunomodulating effects, not toxicological signs. In addition, some sporadic accidental findings such as congestion spots, cyst formation in kidney, atrophy of thymus and spleen with depletion of lymphoid cells, and edematous changes of uterus with desquamation of uterus mucosa as estrus cycles were detected throughout the whole experimental groups including both male and female vehicle controls. The significant (p<0.01) increases of absolute weights of kidney and pancreas detected in BSS extracts 1000 mg/kg-treated female group are considered as secondary changes from increases of body weights. The results obtained in this study suggest that the BSS extract is non-toxic in mice and is therefore likely to be safe for clinical use. The LD50 and ALD of BSS aqueous extracts in both female and male mice were considered as over 2000 mg/kg because no mortalities were detected upto 2000 mg/kg that was the highest dose recommended by KFDA and OECD. In addition, the MTD of BSS extracts was also considered as over 2000 mg/kg because no BSS extracts-treatment related toxicological signs were detected at histopathological observation except for BSS or their component-related pharmacological effects, the immunomodulating effects detected in the present study.

Background and Objectives : Panax ginseng C.A. Meyer is a medical plant that has been widely utilized as a tonic and nutritional agent since ancient times in Korea. Ginseng has anti-metastatic property of cancer and immunomodulating activity. The novel acidic polysaccharide compound(MB40) was isolated from the leaves of Panax ginseng C.A. Meyer. To determine immunomodulating activities of MB40, we evaluate anti-cancer and anti-metastatic effects of MB40 in tumor bearing immune competent mice. Material and Methods : C3H mice were divided into three equal groups(Cisplatin treatment group, MB40 treat-ment group, Cisplatin and MB40 treatment group) and were transplanted SCC(Squamous Cell Carcinoma) cells(2${\times}$106) to the lateral side of abdomen. From day 4 after transplantation, MB40 was administrated at dose of 10mg/kg, respectively, every other day by intratumoral injection. Cisplatin was systemically administrated at doses of 1mg/kg, respectively, every week by intraperitoneal injection. Results : 5 days after administration, tumors can be palpated in every mice group. After 13 days of administration, the mice group to which MB40 were administrated exhibited reduction in tumor size respectively, compared to cisplatin group. Overall status of mice such as body weight and activity were superior in MB40 group than cisplatin group. Conclusion : The result of this study indicates MB40 may have significant therapeutic effect and decreases complications induced by systemic chemotheraphy. MB40 may be developed as a novel and potent immunotropics to improve the cell immune system and anti-cancer drug for the treatment of cancer patients in head and neck squamous cell carcinoma.

Effects of resveratrol glucosylation on the immunomodulation properties of resveratrol and on the viability of macrophage cells have been studied by using murine macrophage RAW 264.7 cells. Nitric oxide (NO) and interleukin 6 (IL-6) expression in macrophages in vitro were studied after treatment with different concentrations of (E)-resveratrol, (E)-resveratrol 3-O-${\beta}$-${\small{D}}$-glucoside (R-3-G), or (E)-resveratrol 4'-O-${\beta}$-${\small{D}}$-glucoside (R-4'-G). In vitro viability of RAW 264.7 cells after treatment with the aforementioned three compounds was also studied. As demonstrated by macrophage cell viability assays, two different resveratrol monoglucosides, R-3-G and R-4'-G, exhibited 50-80% reduced cytotoxicity in comparison to (E)-resveratrol in A549 and HepG2 cells. Compared to the resveratrol aglycon, both glucosylated resveratrol derivatives positively modulated NO and IL-6 production in macrophages positively via transcriptionally up-regulating IL-6 and iNOS expression. Conjugation of a glucose moiety on resveratrol was found to enhance the immunomodulating activity of resveratrol and the viability of RAW 264.7 cells.

Objectives: This study was designed to investigate the anti-tumor metastasis by anti-inflammatory and innate immunomodulating effects of extracts of Jipae-san on cancer cells. Methods: Antimetastatic experiments were conducted in vivo mouse model by using 4T1 mouse mammary carcinoma cells. Cell viability of Jipae-san was tested with 4T1 mouse mammary carcinoma cells, colon 26-M3.1 carcinoma cells and macrophage. In addition expression of $TNF-{\alpha}$ and NO induced by LPS was measured after treating with Jipae-san. To observe innate immunomodulating effects of Jipae-san on macrophage, we measured $TNF-{\alpha}$, IL-12, IL-6 and MCP-1, respectively. Cell cytotoxicity was tested with the macrophage stimulated with Jipae-san and we evaluated the activation of $TNF-{\alpha}$ and NO. And the effect of Jipae-san on metastasis was measured without NK-cell using GM1 serum. Results: Intravenous inoculation of Jipae-san significantly inhibited metastasis of 4T1 mouse mammary carcinoma cells. In an in vitro cytotoxicity analysis, cell growth are closer to 100% less than $1,000{\mu}g/ml$ concentration. The expression of $TNF-{\alpha}$ and NO induced by LPS after treating Jipae-san was down regulated in dose-dependent manner. Level of cytokines such as $TNF-{\alpha}$, IL-12, IL-6 and MCP-1 of Jipae-san group were up regulated in compared to the control group. The macrophage stimulated with Jipae-san significantly inhibits the cancer cell at ratio of 10:1, 20:1. The activation of NO was significantly up regualted in a group of 5:1, 10:1, 20:1. The depletion of NK-cells by anti-asialo GM1 serum partly abolished the inhibitory effect of Jipae-san on tumor metastasis. Conclusions: Jipae-san appears to have considerable activity on the anti-metastasis by inflammation control and activation of innate immune system.

In order to examine the functionality of broccoli sprout (Brassica oleracea, BS), solvent extracts were prepared and their anti-oxidative and immunomodulating activities were compared with those of broccoli (B). EtOH extracts (E) were potently higher than hot-water extracts (HW) in the antioxidant contents and radical scavenging activity. In particular, the total polyphenolic contents in addition to ABTS and DPPH radical scavenging activity were significantly higher in EtOH extract of broccoli sprout (BS-E; 9.15 mg GAE/g, 4.52 mg AEAC/g, and 1.14 mg AEAC/g) compared with that of broccoli (B-E; 7.83 mg GAE/g, 3.63 mg AEAC/g, and 0.97 mg/AEAC/g). Whereas, total flavonoid content was significantly higher in B-E (1.60 mg QE/g) than BS-E (1.43 mg QE/g). Anti-inflammatory activity was investigated using LPS-induced cell line model at a concentration of $10{\sim}100{\mu}g/mL$, in which all solvent extracts of both broccoli sprouts and broccoli were not toxic to RAW 264.7 cell lines. In anti-inflammatory activity of broccoli sprouts, EtOH extracts also showed significantly more potent activity than hot-water extracts in all sample concentrations tested. In addition, BS-E ($100{\mu}g/mL$) inhibited nitric oxide (NO) and IL-6 production to 60.9% and 68.9% compared with the LPS inflammation group (without extracts), whereas B-E inhibited 49.6% and 54.9%. On the other hand, in immunostimulating activity by splenocytes and macrophages, hot-water extract showed significantly higher activity than EtOH extract. Especially, BS-HW stimulated the splenocyte proliferation (1.2-fold against saline group) and IFN-${\gamma}$ production (264.39 pg/mL) at $100{\mu}g/mL$, and the production of IL-6 (1.33-fold), IL-12 (1.09-fold) and TNF-${\alpha}$ (1.49-fold) from macrophages was also significantly enhanced over broccoli. In conclusion, broccoli sprouts showed more potent anti-oxidative, anti-inflammatory and immunostimulating activity than broccoli, suggesting the possibility of using broccoli sprouts as functional food materials.

Purpose: Upper respiratory tract infections are major causes of the common cold throughout the world. Cordyceps militaris (C. militaris) is a well-known functional food for its anti-fatigue and immunomodulating activities. On the other hand, there are no reports on the protective effect against upper respiratory tract infections (URI). This study was a 12 week randomized, double-blind, and placebo-controlled trial in healthy volunteers. Methods: A total of 100 subjects 20 ~ 70 years of age with a history of at least two colds in the year were enrolled in the study. The participants were required to record any adverse events and rate any cold-related incidents in a diary during the investigation period. The efficacy end point was the symptoms and incidence of URI, and changes in cytokines, IgA and natural killer (NK) cell activity. Results: The Cordyceps militaris group over 12 weeks showed no significant impact on the incidence and symptomatology of URI compared to the placebo group. On the other hand, the experimental group showed significantly higher NK cell activity (p = 0.047) and IgA level (p = 0.035) compared to the placebo group. The NK-cell activity and IgA level were increased significantly by Cordyceps militaris over 12 weeks. Conclusion: The results suggest the possible beneficial immunomodulating effects, but the protective effects on URI could not be demonstrated under these conditions. Additional research will be needed to determine the efficacy and mechanisms of Cordyceps militaris function.

Chlorophytum borivilianum Baker (Antharicaceae) commonly referred as 'Safed Musli' has been widely used in the Indian traditional systems of medicine to treat various diseases like rheumatism apart from having immunomodulating property and is used as general tonic. It is also known as 'Ayurvedic viagra' for its aphordisiac properties. C. borivilianum was screened for the first time to determine its antioxidant activity, isolation of the sapogenins and standardization of the isolated sapogenin fraction using HPTLC. Potent antioxidant activity of ethanolic extract was found by their ability to scavenge DPPH (84.51%), hydroxyl radical (48.95 %), ferryl bi-pyridyl complex (84.53%) along with the inhibition of lipid peroxidation (67.17%) at $100\;{\mu}g/ml$ concentration. The ethanolic extract also exhibited significant inhibition of superoxide anion radical generated by photochemiluminescence. Thus, the potent antioxidant activity validates the innumerable therapeutic claims of the plant in the traditional system especially its use as a Rasayana drug.
