The present experiments were designed to study the influence of WalgookwhanhabBojoongikgitang on immune functions of Balb/c mice under stress condition. WalgookwhanhabBojoongikgitang was orally administered to the mice for 15 days. On the 10th day the mice were immunized with sheep red blood cells (SRBC) and then subjected to electric footshock for 5 days (2 sessions a day, 11 footshocks a 31 min-session). The immune responses to SRBC were determined by means of hemagglutination and BIT cell populations in the spleen were studied by FACS analysis on the 16th day. The results were as follows. 1. After electric footshock, IDlce became sluggish and crowded to one side of the cage. Increased antibody titer for SRBC, increased B cell population, and decreased T cell population in the spleen were also observed. These results confirm that electric footshock caused stress inducing immunological and behavioral changes in Balblc mice. 2. Walgookwhanhab-Bojoongikgitang administration significantly antagonized the effect of electric footshock on the antibody titer for SRBC. As a result, antibody titers for SRBC in the mice treated with Walgookwhanga-Bojoongikgitang were maintained at the similar levels as those of control group mice even after the electric foots hock. 3. Walgookwhanhab-Bojoongikgitang administration also antagonized the effect of electric footshock on the BIT populations in spleen. As a result, Band T populations in the mice treated with Walgookwhanhab-Bojoongikgitang were maintained at the similar levels as in the control group mice even after the electric footshock. Taken together, Walgookwhanhab-Bojoongikgitang seem to help Balb/c mIce to maintain their humoral immune response and immune cell populations at a normal range under the stress conditions, suggesting its possible therapeutic use as a immune function modulator.

Objective: This experiment was conducted to find out the immunological effects of wheat phytase when long-chain inorganic polyphosphate (polyP) treated with wheat phytase was added to a macrophage cell line, Raw 264.7, when compared to intact long-chain polyP. Methods: Nitric oxide (NO) production of Raw 264.7 cells exposed to P700, a long-chain polyP with an average of 1,150 phosphate residues, treated with or without wheat phytase, was measured by Griess method. Phagocytosis assay of P700 treated with or without phytase in Raw 264.7 cells was investigated using neutral red uptake. The secretion of tumor necrosis factor α (TNF-α) by Raw 264.7 cells with wheat phytase-treated P700 compared to intact P700 was observed by using Mouse TNF-α enzyme-linked immunosorbent assay kit. Results: P700 treated with wheat phytase effectively increased NO production of Raw 264.7 cells by 172% when compared with intact P700 at 12 h exposure. At 5 mM of P700 concentration, wheat phytase promoted NO production of macrophages most strongly. P700, treated with wheat phytase, stimulated phagocytosis in macrophages at 12 h exposure by about 1.7-fold compared to intact P700. In addition, P700 treated with wheat phytase effectively increased in vitro phagocytic activity of Raw 264.7 cells at a concentration above 5 mM when compared to intact P700. P700 dephosphorylated by wheat phytase increased the release of TNF-α from Raw 264.7 cells by 143% over that from intact P700 after 6 h exposure. At the concentration of 50 μM P700, wheat phytase increased the secretion of cytokine, TNF-α, by 124% over that from intact P700. Conclusion: In animal husbandry, wheat phytase can mitigate the long-chain polyP causing damage by improving the immune capabilities of macrophages in the host. Thus, wheat phytase has potential as an immunological modulator and future feed additive for regulating immune responses caused by inflammation induced by long-chain polyP from bacterial infection.

Objectives: This study was designed to investigate intestinal immune system activation and anti-metastatic effect on cancer cells by orally administered extracts of Boyanghwano-tang. Methods: To observe immunomodulating effects of Boyanghwano-tang on Peyer's patch cells, we measured cytokines GM-CSF, IL-4. In addition to observing effects of Boyanghwano-tang on hematopoiesis, we measured proliferation of bone marrow cells mediated by Peyer's patch cells in vitro. IgA induction activated in intestinal content and serum was measured to observe the effect of orally administered Boyanghwano-tang on mucosal immune system. After administering ovalbumin (OVA) with Boyanghwano-tang, Proliferation of Peyer's patch cell was measured to investigate gut immunostimulatory effect. Anti-metastatic experiments were conducted in vivo mouse model by using colon 26-M3.1 carcinoma cell. Results: The amounts of GM-CSF and IL-4 in the culture supernatant of Peyer's patch cells were significantly increased compared to the control group. The proliferation of bone marrow cell was significantly up-regualted with Boyanghwano-tang. These results indicate that oral administration of Boyanghwano-tang enhances the secretion of hematopoietic growth factors such as GM-CSF and IL-4 from Peyer's patch cells, and these cytokines also act on modulator of bone marrow cell proliferation. After orally administering OVA with Boyanghwano-tang, IgA induction and Proliferation of peyer's patch cell was up-regulated with Boyanghwano-tang. These results means orally administered Boyanghwano-tang activates intestinal immune system and has an inhibitory effect on tumor metastasis. In addition, We found that orally administered Boyanghwano-tang significantly inhibited tumor metastasis in vivo. Conclusions: Orally administered Boyanghwano-tang appears to have considerable activity on the anti-metastasis by activation of immune system.

Objectives: This study was designed to investigate intestinal immune system activation and antimetastatic effect of Ojeok-san on cancer cells by oral administration. Methods: Cell viability of Ojeok-san was tested with colon 26-M3.1 carcinoma cells and Peyer's patch cells in vitro. Antimetastatic experiments were conducted in vivo mouse model by using colon 26-M3.1 carcinoma cell. To observe immunomodulating effects of Ojeok-san on Peyer's patch cells, we measured interleukin (IL)-4, GM-CSF. In addition to observing effects of Ojeok-san on hematopoiesis, we measured proliferation of bone marrow cells mediated by Peyer's patch cells in vitro. IgA induction activated in serum and intestinal content was measured to observe the effect of orally administered Ojeok-san on mucosal immune system. After administering Ovalbumin (OVA) with Ojeok-san, Proliferation of Peyer's patch cell was measured to investigate gut immunostimulatory effect. Results: in vitro cytotoxicity analysis, the inhibitory concentration $(IC)_{50}$ of the colon 26-M3.1 carcinoma cell was $890{\mu}g/ml$. $IC_{50}$ of the Peyer's patch cells with LPS was $990{\mu}g/ml$. We found that orally administered Ojeok-san significantly inhibited tumor metastasis in vivo. In addition, the amounts of IL-4 and GM-CSF in the culture supernatant of Peyer's patch cells were significantly increased compared to the control group. The proliferation of bone marrow cell was significantly up-regulated with Ojeok-san. These results indicate that oral administration of Ojeok-san enhances the secretion of hematopoietic growth factors such as GM-CSF and IL-4 from Peyer's patch cells, and these cytokines also act on modulator of bone marrow cell proliferation. After orally administering Ovalbumin (OVA) with Ojeok-san, IgA induction and Proliferation of peyer's patch cell was up-regulated with Ojeok-san. These results means orally administered Ojeok-san activates intestinal immune system and has an inhibitory effect on tumor metastasis. Conclusions: Orally administered Ojeok-san appears to have considerable activity on the anti-metastasis by activation of immune system.

Human milk, which nourishes the early infants, is a source of bioactive components for the infant growth, development and commensal formulation as well. Human milk oligosaccharide is a group of complex and diverse glycans that is apparently not absorbed in human gastrointestinal tract. Although most mammalian milk contains oligosaccharides, oligosaccharides in human milk exhibit unique features in terms of their types, amounts, sizes, and functionalities. In addition to the prevention of infectious bacteria and the development of early immune system, human milk oligosaccharides are able to facilitate the healthy intestinal microbiota. Bifidobacterial intestinal microbiota appears to be established by the unilateral interaction between milk oligosaccharides, human intestinal activity and commensals. Digestibility, membrane transportation and catabolic activity by bacteria and intestinal epithelial cells, all of which are linked to the structural of human milk oligosaccharides, are crucial in determining intestinal microbiota.

To investigate the mechanism of germ cell death in postnatal stage of mouse, the involvement of apoptotic executioners, caspase-3 and caspase-activated DNase(CAD), and apoptotic initiators, Bax Fas and Fas ligand, in the germ cell death has been studied. Immune-labels of active caspase-3 and CAD were located in TUNEL-positive, apoptotic, oocytes as well as normal oocytes of primary or secondary follicles. CAD immune-labels were also detected in the nucleus of TUNEL-positive oocytes. Most of oocytes showing positive immune-labeling of active caspase-3 or CAD had vacuoles in their cytoplasm, which is the morphological characteristic of oocyte during folliclar atresia. Bax immune-stains were detected in the atretic oocytes which showed the vacuole in their cytoplasm. Positive immune-labels for Fas ligand was localized in TUNEL-positive or atretic oocytes. Presence of immunoreactivity of active caspase-3 and CAD in TUNEL-positive germ cells implicate that active raspase-3 and CAD might play a role in germ cell apoptosis during early development of mouse ovarian follicle. Immunohistochemical localization of Bax and Fas ligand in TUNEL-positive oocytes suggests that these might be the most plausible modulator of oocyte apoptosis.

When pine (Pinus densiflora) needles were fractionated into cold water (PD-CW), hot water (PD-HW) and methanol extract (PD-M), PD-M showed potent simulating activity (1.19-fold of the saline control) for proliferation of bone marrow cells mediated by Peyer's patch cells in vitro. MeOH extracts were prepared by homogenization, stirring or reflux to identify the method of methanol extraction, and MeOH extract by reflux method showed significantly highest intestinal immune system modulating activity (1.30-fold) in vitro. The intestinal immune system modulating effect of orally administered PD-M fractionated from pine needles also were studied in mice. Analyzing intestinal immune system modulating activity mediated Peyer's patch cells from C3H/He mice which had been fed with PD-M at different doses for 7 days, 1.0 g/kg of BW/day indicated that the bone marrow cells had proliferated (3.65-fold of 3% EtOH administered group). In addition, the amounts of IL-6 in the culture supernatant of Peyer's patch cells at 1.0 g/kg of BW/day were increased (1.13-fold) whereas the production of GM-CSF was not dose dependent. These results indicate that oral administration of PD-M enhances the secretion of hematopoietic growth factors such as GM-CSF and IL-6 from Peyer's patch cells, and these cytokines also act on modulator of bone marrow cell proliferation.

In this paper, we present evidence that the Korean red ginseng extract shows the immunomodulatory activities during postoperative chemotherapy after curative surgery in patients with advanced colon cancer. We measured the circulating interleukin-2 (IL-2), interleukin-8 (IL-8)and interleukin-10 (IL-10) as a immune modulator to evaluate the effect of Korean red ginseng. The mean preoperative value of IL-2 was similar in the non-RG group and the RG group (5.72 pg/ml versus 6.87 pg/ml, p>0.05). The mean value of IL-2 was compared with IL-2 from healthy control group, there was no significant difference (14.89 pg/ml versus 14.22 pg/ml, p>0.05). The mean preoperative value of IL-8 was higher in the non-RG group comparing with the RG group (30.92 pg/ml versus 36.25 pg/ml, p < 0.05). At postoperative 3 month, the mean values of IL-8 from non-RG and RG group down to 24.56 pg/ml and 21.46 pg/ml respectively. The IL-8 of RG group at 3 month showed no difference with that of HC group(21.46 pg/ml versus 16.31 pg/ml, p>0.05). The preoperative mean value of IL-10 of non-RG, RG and HC group was 11.56 pg/ml, 10.8 pg/ml, and 3.68 pg/ml respectively. At postoperative 3 month, the mean values of IL-10 from non-RG and RG group down to 8.45 pg/ml and 5.04 pg/ml respectively. In spite of decreasing IL-10 levels of both cancer Patients group with time, there was still significant difference with that of HC group (non-RG versus HC group, p=0.00, RC versus HC group, p=0.04). The results of this study suggest that the red ginseng extract may have some immunomodulatory properties associated with IL-2, IL-8 and IL-10 activity in patients with advanced colorectal cancer during postoperative chemotherapy. We think to need the further studies and a larger sample size to fully evaluate the antitumor effect of ginseng and need to establish this mechanism of action as well as identify the active components associated with antitumor activity and immunomodulation in patients with advanced colorectal cancer.
