  • Bangpungtongseong-san(BPTSS, Fangfengtongsheng-san in Chineses) is a traditional herbal formula comprising 18 medicinal herbs. In the present study, we performed the simultaneous analysis for four compounds of BPTSS and examined anti-allergic effects in human keratinocytes and mouse splenocytes. The column for separation of four compounds was used Luna C18 column and maintained at 40℃. The mobile phase for gradient elution consisted of two solvent systems. The analysis was carried out at a flow rate of 1.0 mL/min with PDA detection at 254 and 280 nm. To evaluate production and expression of Th2 chemokines, ELISA and RT-PCR were conducted in tumor necrosis factor (TNF)-α and interferon (IFN)-γ-stimulated HaCaT cells with or without BPTSS or silymarin, a positive control for skin inflammation. To measure Th2 cytokines, primary mouse splenocytes were treated with BPTSS and performed ELISA for interleukin (IL)-4, 5, 13. Calibration curves were acquired with r2>0.9999. The contents of geniposide, liquiritin, baicalin, and glycyrrhizin in BPTSS were 5.06 ㎎/g, 7.33 ㎎/g, 27.56 ㎎/g, and 7.81 ㎎/g, respectively. BPTSS reduced TARC and RANTES production and mRNA expression in TNF-α and IFN-γ-treated HaCaT cells. BPTSS inhibited IL-4, 5, and 13 production in mouse splenocytes. Our data will be a helpful information to upgrade quality control and anti-allergic effects of BPTSS.

  • A fucoidan, isolated from Korean Undaria pinnatifida spoprophyll (UP-F), was investigated for its immunomodulating activity on murine macrophages and splenocytes, and its activity was compared with that of fucoidan from Fucus vesiculosus (FV-F). Treatment of UP-F resulted in inhibition of the growth of murine macrophage RAW 264.7 cells, but its cytotoxicity was not observed in normal murine splenocytes. FV-F was shown to be highly cytotoxic to both immune cells, and its cytotoxic activity was higher than that of UP-F. Treatment of UP-F induced TNF-α in a dose-dependent manner from two types of macrophages, RAW 264.7 cells and murine peritoneal macrophages. The TNF-α-inducing activity of UP-F was higher than that of FV-F. UP-F also actively induced chemokines (RANTES and MIP-1α) from RAW 264.7 cells. Furthermore, treatment of UP-F gave rise to activation of murine splenocytes to produce cytokine (IL-6) and chemokines (RANTES and MIP-1α), showing significantly higher activity than that of FV-F. These results indicate that UP-F is less cytotoxic to immune cells than FV-F, and possesses immunomodulating activity to produce cytokines and chemokines from macrophages and splenocytes.

  • Total spleen lymphocytes, lymphocyte proliferation, tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), and interleukin-10 (IL-10) in spleen lymphocyte culture were studied in malnourished Wistar rats fed with goat milk yoghurt. Malnourished rats were created by using standard feed restriction as much as 50% of normal rats for 21 d. Goat milk yoghurt containing three types of microorganism e.g., Lactobacillus acidophilus, Sterptococcus thermophilus and Bifidobacterium longum derived from Lacto-B culture in powder form. After 21 d, the rats continued to receive restricted feeding and supplemented with goat milk yoghurt for 7 d. Total splenocytes were counted by hemocytometer. Splenocytes proliferation was expressed as stimulation index, whereas the TNF-${\alpha}$ and IL-10 of spleen lymphocyte culture were measured by ELISA technique. The total number of splenocytes and stimulation index of splenocytes in moderate malnourished and normal rats supplemented with goat milk yoghurt was not significantly different. The level of TNF-${\alpha}$ in the rat supplemented with goat milk yoghurt was lower (p<0.05) than the control group, whereas the level of IL-10 in the rat supplemented with goat milk yoghurt was higher (p<0.05) than the control group. In conclusion, goat milk yoghurt supplementation in malnourished rats could decrease TNF-${\alpha}$ as a representation of the pro-inflammatory cytokine, while it increases IL-10 as a representation of the anti-inflammatory cytokine.

  • Aster scaber $T_{HUNB}$ (AST ; Charm-chui), a potent herbal medicinal plant, has a long tradition of use, being harvested as a wild plant, is said to stimulate appetite, and may act as a diuretic, antifebrile agent and painkiller. This study was conducted to investigate the immunomodulative effects of AST In mice, using in vitro and in vivo experiments. The immunomodulative effects were studied in vitro by measuring the proliferation of mice splenocytes and the production of three kinds of cytokines (IL-$\beta$, IL-6, and TNF-$\alpha$) by mice peritoneal macrophages which were cultured with sequential fractions of AST methanol extract (methanol, hexane, chlo-roform, ethylacetate, butanol and water). In an in vivo experiment using mice, different concentrations of AST water extract were orally administrated every other day for two weeks. The production of cytokines (IL-1$\beta$, IL-6, and TNF-$\alpha$) secreted by activated macrophages, and the proliferation of mice splenocytes, were used as indices for immunocompetence. In vitro supplementation using six fractions of AST in the range of 1 to 100$\mu$ g/ml enhanced splenocyte proliferation by 10.5% to 53% compared to the control. IL-1$\beta$production was significantly increased with the supplementation of butanol and water extracts of AST. Higher levels of IL-6 and TNF-$\alpha$production were detected with supplementation of methanol, ethylacetate, butanol or water extracts at the concentration of 100$\mu$ g/ml. In the in vivo study, the highest proliferation of splenocytes was seen in the mice orally administrated with the AST water extract at the concentration of 500mg/kg body weight. In the case of cytokine production, there were no significant differences in the production of IL-1$\beta$and IL-6 among the treated groups and the control. However, TNF-$\alpha$released by activated peritoneal macrophages were augmented by the oral administration of AST water extract. These results indicate that AST may enhance the immune functions by regulating splenocyte proliferation and cytokine production capacity in mice.

  • Cordycepin was purified from a mushroom, Cordyceps militaris, and its effect on Th1 and Th2 cytokines was examined. The level of cytokine induction in mouse splenocytes was estimated after co-inoculation of purified cordycepin and LPS. When $5{\mu}g/ml$ of purified cordycepin was exposed to mouse splenocytes for 72 h, the level of a Th1 cytokine IL-12 increased by 2.9-fold. The addition of the purified cordycepin to splenocytes also increased the level of Th2 cytokines, IL-4 and IL-10, by 1.9- and 1.8-fold, respectively. Therefore, cordycepin increases the cytokine levels and may contribute to the up-regulation of cellular and humoral immunity.

  • Radiotherapy is an irreplaceable method of cancer treatment but, it has various side effects, especially damage to the hemopoietic system. A lot of radioprotectors have been found but they also have toxic effects. Many kinds of crude drugs(Oriental Chinese medicine)with low toxicity have been reported to promote the recovery from radiation damage. Recently, the trial to combine radiotherapy with herbal treatment of cancer patients shows a desirable result, an enhancement in recovery of the blood system.. This study was performed to determine whether prescriptions to support the healthy energy and strengthen the body resistence, Buzhongyiqi-tang and Siliu-tang, promote the recovery of splenocytes of N:GP(s) mice from radiation damage. We investigated the proliferative effect of Buzhongyiqi-tang, Siliu-tang and EIB(ethanol insoluble fraction of Buzhongyiqi-tang) on N:GP(S)mice splenocytes before or after ${\gamma}$-irradiation. We also investigated the morphology of splenocytes cultured with these herbs. Buzhongyiqi-tang and Siliu-tang promoted the proliferation of splenocytes in a concentration of 0.1 mg/ml compared with normal control(p<0.001). After 1-5Gy of ${\gamma}$-irradiation they also showed the effect of recovery of hemopoietic cells, especially in Buzhongyiqi-tang(4Gy:p<0.005; 5Gy:p<0.05). In addition, EIB(ethanol insoluble fraction of Buzhongyiqi-tang) showed the highest proliferative effect of all agents suggesting that more effective fractions could be found from crude herbs or prescriptions. These results suggest that it is possible to make use of Buzhongyiqi-tang, Siliu-tang or EIB as radio-protective agents.

  • Vegetable soup has been reported to have anti-inflammatory, anti-oxidative and anti-cancer effects. In this study, five kinds of vegetable soup were developed using a new manufacturing process and compositional changes in raw material, and anti-cancer and immuno-stimulatory activities were evaluated. Cytotoxicity tests based on MTT assay revealed that all vegetable soups had strong inhibitory effects against CT26 mouse colon cancer cells, with soups including Solomon's seal being most effective based on comparison of $IC_{50}$ values. Apoptosis in response to vegetable soup was occurred by 3-5 fold on cancer cells compared to normal cells. Mouse splenocytes increased by 266-541% in response to addition of vegetable soup in an in vitro proliferation experiment. In co-culture with splenocytes and CT26 cancer cells, splenocytes increased by more than 280% in every vegetable soup treatment, while cancer cells decreased by about 60% and cytokines such as $IFN- {\gamma}$ and IL-12 were secreted from splenocytes in high levels only in response to vegetable soup including Solomon's seal. In conclusion, all vegetable soups developed in this study had anti-cancer effects, and vegetable soup including Solomon's seal showed the strongest anti-cancer and immuno-stimulatory effects. These results suggest that functionality of vegetable soup could be increased by changes in manufacturing processes and raw materials composition.

  • 마우스의 비장세포에 아로마 에센셜 오일 중 eucalyptus나 geranium에 노출된 마우스비장세포로부터 생성되는 in-terleukin (IL)-2와 IL-4를 정량 분석하였다. Eucalyptus를 노출시킨 비장세포에서 IL-2의 생성은 저농도의 오일 노출의 경우 대조군에 비하여 증가한 반면 고농도에서는 감소를 보였으며 geranium을 노출시켰을 때에도 유사한 경향을 보였다. 따라서 eucalyptus나 geranium를 생체에 적용할 때 저농도하에서 T세포 증식을 포함하는 IL-2 관여 면역반응이 증강될 것으로 보인다. 비장세포에서 IL-4의 생성은 eucalyptus 고농도에서 증가를 보이지만 저농도에서는 큰 변화를 보이지 않았으며 geranium의 경우는 농도 의존적으로 증가하는 양상을 보였다. 따라서 eucalyptus나 geranium을 생체에 적용하였을 때 IL-4 증가는 B세포 증식을 포함하는 IL-4관련 여러 가지 면역반응을 상향시킬 것으로 예상된다.

  • There is an increasing interest in using inactivated probiotics to modulate the host immune system and protect against pathogens. As the immunomodulatory function of heat-killed Lactobacillus brevis KCTC 12777BP (LBB) and its mechanism is unclear, we investigated the effect of LBB on immune response based on the hypothesis that LBB might exert stimulatory effects on immunity. In the current study, we demonstrate that administration of LBB can exert immune-stimulatory effects and promote clearance of foreign matters through enhancing phagocytosis. Treatment with LBB induced the production of TNF-α, IL-6, and nitric oxide in macrophages. Importantly, LBB directly increased the phagocytic activity of macrophages against bacterial particles. LBB was able to promote the production of TNF-α in bone marrow-derived macrophages and splenocytes and also increase the proliferation rate of splenocytes, suggesting that the immune-stimulating activity of LBB can be observed in primary immune cells. Investigation into the molecular mechanism responsible revealed that LBB upregulates TAK1 activity and its downstream ERK, p38, and JNK signaling pathways. To further confirm the immunomodulatory capability of LBB in vivo, we orally administered LBB to mice and assessed the effect on primary splenocytes. Splenocytes isolated from LBB-treated mice exhibited higher TNF-α expression and proliferative capacity. These results show that heat-killed L. brevis, a wildly consumed probiotic, may provide protection against pathogens through enhancing host immunity.

  • The purpose of this research was to investigate the effects of Kamikwibitang water extract (KKT) on immobilization stress in C57BL/6J mice. KKT decreased the serum level of histamine and corticosterone increased by immobilization stress. In addition, KKT decreased the cell viability of thymocytes and enhanced the cell viability of splenocytes decreased by immobilization stress. Also, KKT decreased the viability of thymocytes and splenocytes in vitro. KKT decreased DNA fragmentation of splenocytes increased by immobilization stress. KKT decreased the population of thymic $CD4^+CD8^-$ cells increased by immobilization stress, and did not affect the population of $B220^+$ cells and the population of $Thy1^+$ cells changed by immobilization stress and enhanced the population of splenic $CD4^-CD8^+$ cells increased by immobilization stress. KKT enhanced the production of ${\gamma}-interferon$ and did not affect the production of interleukin-2 and interleukin-4 decreased by immobilization stress. Also, KKT decreased the phagocytic activity and the level of nitric oxide decreased by immobilization stress. These results indicate that KKT may be useful for the prevention and treatment of stress via suppression of serum histamine and corticosterone level and enhancement of specific-immune response.
