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.

Objectives : We recently have reported that constituents of OMC-2010 have an immuno-modulatory effects via inhibiting tumor necrosis factor (TNF)-alpha and interleukin (IL)-5. In this study, based on previous data, we investigated the effects of combinations with each OMC constituents on splenocyte cytotoxicity, cytokine productions, and ovalbumin (OVA) induced experimental allergic asthma. Methods : Mouse splenocytes were pre-treated with ethanol extract of constituents of Rehmannia glutinosa (RG), Pinellia ternata (PT), Schisandra chinensis (SC). We made 4 combinations using RG, PT, and SC (A;1:1:1, B;2:1:1, C;1:2:1, D;1:1:2). The cells were pretreated with A, B, C, or D for 1 h, then stimulated with lipopolysaccharide (LPS, $1{\mu}g/ml$) for 48 h. Then the cells were harvested for real-time reverse transcription polymerase chain reaction to detect cytokine productions. Then using effective combination from RG, PR and SC, we administrated the combination orally, then challenged with OVA to induce asthma. Then we analyzed the airway hyper-reactivity (AHR), lung histology and lung TNF-${\alpha}$ and IL-5 mRNA. Results : A. B. C. and D did not showed significant cytotoxicity on splenocytes. Pre-treatment of A inhibited the expression of TNF-${\alpha}$ and IL-5 significantly, but not B, C, and D. In experimental asthma, administration of A significantly inhibited the increase of AHR, lung damage, TNF-${\alpha}$ and IL-5 expression. Conclusions : Theses results could suggest that inhibitory effects of the ideal combination with RG, PT and SC (1:1:1) could be applied to treatment of asthma and study of asthma mechanisms.

Objective : In the present study, we investigated the pharmacological profile of the aqueous extract of $Patrinia$ $scabiosaefolia$ Fischer ex Link (EPS) and $Patrinia$ $villosa$ Jussieu (EPV) for its anti-asthmatic activities. The purpose of this study is to ascertain if EPS result in better anti-asthmatic activities and functional outcome as compared with EPV. Methods : In this study, BALB/c mice were systemically sensitized to ovalbumin (OVA) followed intratracheally, intraperitoneally, and by aerosol allergen challenges. We investigated the effect of EPS, EPV on the recruitment of pulmonary inflammatory cells, various immune cell phenotypes, Th1/Th2 cytokine gene expression and production and histamine production in serum. Results : In BALB/c mice, we found that EPV-treated groups had more effectively suppressed inflammatory cell infiltration of lung and BALF, B220+IgE+, CD11b+Gr-1+ cell population in lung and these occurred by suppressing the gene expression of IL-4, IL-5 and IL-4 cytokine production in BALF and serum. Conclusions : These results suggest that EPV may play an important role in the control of anti-asthmatic activities by down-regulation of Th2 cytokine (especially IL-4, IL-5). In general, EPV has shown a better anti-asthmatic activities compared to EPS.

Objective : This study is conducted to evaluate the efficiency of ethanol extracts of 4 mixed herbs(CP001 or CP002) on mouse model of atopic dermatitis induced by ovalbumin. Methods : Female BALB/c mice were internally sensitized with ovalbumin($20{\mu}g$) plus aluminum hydroxide hydrate(4mg) once per week. After 3 weeks, they were dermally challenged with patches containing ovalbumin ($100{\mu}g$) plus aluminum hydroxide hydrate(20mg) every other day for 3 weeks. After induction of atopic dermatitis, mice back skin were gently rubbed with CP001 or CP002(200mg/$m{\ell}$, $100{\mu}{\ell}$) for two weeks(every 2 days). Results : In CP001 or CP002 treated group, there was a remarkable reduction in infiltration of eosinophils on the skin areas and diminution of mast cells and total T cells in blood samples as compared with control group. Cutaneous expressions of interleukin-13, 17 were also decreased by CP001 or CP002. Moreover, blood immunoglobulin E level was decreased by drug administration while there was no decrease in OVA sensitization group. Conclusion : In summary, our result shows that herbal extracts(CP001 and CP002) could be potential candidates for the treatment of chronic atopic dermatitis.

Individual immunochromatographic assays (ICG) for ochratoxin A (OTA) and zearalenone (ZEA) were optimized and used in the development of a one-step simultaneous immunochromatographic assay (OS-ICG) for the rapid multianalysis of two mycotoxins in corn samples. The nitrocellulose membrane of the OS-ICG was treated with OTA-bovine serum albumin (BSA), ZEA-ovalbumin (OVA), and anti-mouse IgG in the OTA test, ZEA test, and control zones, respectively. Monoclonal antibody-gold conjugates (OTA3 MAb-gold and ZEA2C5 MAb-gold) were sprayed onto the conjugate pad. The visual detection limits were 2.5 and 5 ng/ml for OTA and ZEA, respectively, and the results were obtained within 15 min after starting the analysis. An efficient, simple, and rapid extraction method using 30% MeOH/PBS was established and validated by analyzing the corn samples spiked with OTA/ZEA mixtures (0/0, 5/10, 10/20, and $20/30\;{\mu}g/kg$). The cut-off values of the OS-ICG for the spiked corn were 5 and $10\;{\mu}g/kg$ for OTA and ZEA, respectively. Natural corn samples were analyzed by OS-ICG, direct competitive enzyme-linked immunosorbent assay (DC-ELISA), and HPLC. Results of the OS-ICG were in good agreement with those obtained by DC-ELISA and HPLC. The developed OS-ICG offers a rapid, easy-to-use, and portable analytical system and can be used as a convenient qualitative tool for the on-site simultaneous determination of OTA and ZEA in cereals, food, and agricultural products in one analytical cycle.

Background &Objectives : Rhinitis is an inflammation of nasal mucosa and the major symtoms are watery rhinorrhea, sneezing, itchy nose, and nasal obstruction. Rhinitis is classified into allergic rhinitis and nonallergic rhinitis. Allergic rhinitis is an immune reaction by allergen, and vasomotor rhinitis which is nonallergic and noninfectious is hypersensitive reaction. The incidence of allergic rhinitis has increased and the rate of vasomotor rhinitis is high. However there have been no studies about vasomotor rhinitis compared with allergic rhinitis. And there have been no studies so far performed on the effect of Tongkwansan. Therefore this study is aimed to find out the effects of Tongkwansan on allergic rhinitis and vasomotor rhinitis. Materials and Methods : Fifteen BALC/c mouses were divided into three groups : normal group, control group and sample group. To induce the allergic rhinitis in control group and sample group, mouses were sensitized intrapertioneally 0.1% ovalbumin solution three times at intervals of 1 week. Then intranasal sensitization was performed by diffusing 0.1 % ovalbumin solution 3 times at intervals of 2 days. After that time, mouses in the sample group were oral administration treated by Tongkwansan for 28 days. We observed changes in the segment of IL-4, IL-5, $IFN-{\gamma}$, Total IgE, and ovalvumin specific IgE in blood. We used the statistical methods of ANOVA test(p<0.05). Results : There were no significant changes statistically in $IFN-{\gamma}$, IL-4, and IL-5 in blood(p<0.05). There were also no significant changes statistically in Total IgE, OVA-specific IgE in blood(p<0.05). Conclusion : According to above results, it is supposed that Tongkwansan has no significant effects on allergic rhinitis. But it is supposed that Tongkwansan has significant effects on vasomotor rhinitis which is nonallergic and noninfectious

난초과의 석곡(石斛; Dendrobii herba) 에탄올 추출물(EED)의 항당뇨 활성 및 항당뇨 기전을 조사하였다. 스트렙토 조 토신에 의해 유도된 당뇨병 마우스에서 EED를 하루 4회 경구 투여하여 공복 혈당, 당화혈색소 수치, 인슐린 수치 및 글루탐산 옥살 아세트산 트랜스 아미나 아제 및 글루탐산 피루브산 트랜스 아미나 아제의 간 기능을 감소시키는 실험연구를 통해 그 약리적 기전을 밝혀내고자 했다. EED는 L6 근육 세포에서 세포 내 포도당 섭취뿐만 아니라 RINm5F 베타 세포에서 포도당에 의한 인슐린 분비를 증가시켰다. 따라서 EED는 인슐린 분비를 증가시킬 뿐만 아니라 세포 당 흡수를 증가시킴으로써 항당뇨병 활성을 나타내는데 커다란 가능성을 보여주었으며, 향후 석곡(石斛; Dendrobii herba) 에탄올 추출물에 대한 약리적 기전에 대한 연구가 더욱 활발하게 이루어져 당뇨병 치료에 큰 공헌을 할 수 있게 되기를 기대해본다.
