The purpose of this research was to investigate the effect of Maekmoondong-tang(MMDT) on the activity of immune cell. The addition of MMDT(10 ㎍/㎖) enhanced the proliferation of cultured-splenocytes and thymocytes. And administration of MMDT(250, 500 ㎎/㎏) accelerated subpopulation of splenic T lymphocytes in BALB/c mice. In contrast, the treatment of the high concentration (500 ㎎/㎏)of MMDT were decreased thymic T lymphocytes. Administration of MMDT(250, 500 ㎎/㎏) eminently enhanced the production of IFN-γ. And MMDT did not affect the cell viability of Jurkat leukemia cells. These results suggest that MMDT have a immunoregulatory effect via enhanced cell mediated immunity

We studied the antioxidative and immunoregulatory properties of 70% ethanol extracts from the leaves, branches, and fruit of 13 species of the Rhamnaceae collected during the bearing season (Berchemia berchemiifolia, Berchemia floribunda, Hovenia dulcis, Paliurus ramosissimus, Rhamnella franguloides, Rhamnus crenata, Rhamnus davurica, Rhamnus koraiensis, Rhamnus parvifolia, Rhamnus ussuriensis, Rhamnus yoshinoi, Sageretia thea, and Ziziphus ujube). Total phenolic and flavonoid content values were determined using calibration curves of gallic acid and rutin, respectively. ABTS and DPPH radical scavenging assays were performed to determine antioxidative potential. Anti-inflammatory effects were studied using the nitric oxide (NO) inhibition assay in LPS-induced RAW264.7 cells. Extracts of Berchemia berchemiifolia, Sageretia thea, and Ziziphus jujuba had the highest total phenol and flavonoid content values. Extracts of Berchemia berchemiifolia, Paliurus ramosissimus, Rhamnella franguloides, and Sageretia thea had the highest ABTS radical scavenging activities. Berchemia berchemiifolia and Sageretia thea had the highest DPPH radical scavenging activities. Furthermore, extracts of Berchemia berchemiifolia, Berchemia floribunda, Paliurus ramosissimus, Sageretia thea, and Ziziphus jujuba showed strong anti-inflammatory activity through inhibition of NO production. The results of this study suggest that Rhamnaceae extracts can be used as natural antioxidants and immunomodulators.

The purpose of this research was to investigate the effects of Chungjokupye-tang(CJKPT) on the anti-carcinogenic action. The cell viability of mouse spienocytes and thymocytes were enhanced by the addition of CJKPT. CJKPT were increased of splenic and thymic T lymphocytes, such as T/sub H/ cells were markedly increased by the treatment of CJKPT in vivo. CJKPT treatment induced the apoptotic cell death of Jurkat and HL60 leukemia cells. CJKPT reduced mitochondrial transmembrane potential and increased the expression of ICE, c-myc and p53 gene in Molt-4cells dose dependant manner. These results suggest that CJKPT have an anti-carcinogenic action via immunoregulatory mechanism.

Inner nutshell of Castanea crenata has been used as an anti-aging and anti-wrinkle agent from the ancient time in east Asia. In order to develop new anti-aging and anti-wrinkle, ethanolic extract of inner nutshell of Castanea crenata was prepared and various biological activities were evaluated. Cor-285 possessed potent tree radical scavenging activity in vitro compared to gallic acid. Cor-285 showed the preventive effect against UV-induced cytotoxicity of fibroblast at concentration of 25-250mg/ml. When Cor-285 was evaluated for its anti-allergic activity, it effectively inhibited histamine release from mast cells induced by compound 48/80. The inhibitory activity was stronger than that of glycyrrhizinate. Cor-285 also showed on vivo inhibition against delayed hypersensitivity as well as croton-oil induced ear edema in mice when topically applied. These results strongly suggest that Cor-285 may reduce immunoregulatory/inflammatory skin trouble. From the attempts to isolate the scavenger, were isolated. In a clinical trial of twenty healthy volunteers with aged skin, 6 weeks application of Cor-285 decreased wrinkle about 26% and increased moisturizing 20% on the skin. All of these results indicate that Cor-285 may be an effective anti-aging and anti-wrinkle agent.

Objectives : To research the trend of studies related to rheumatoid arthritis and to indicate the hereafter direction for its study in oriental medicine and its treatment. Methods : I reviewed 75 domestic oriental medical journals, and 50 medical journals about rheumatoid arthritis published after 2004, and comparative analysis was made. And these theses were classified by college, year, field of study, subject. Results : The following are the results of this study. 1. Classified by oriental medical college, Dae-jeon college published the most theses, followed by Dong-guk, Kyung-hee, Se-myung and Dong-shin college. Han-yang college published the most theses among college of medicine. 2. Classified by type of thesis, experimental theses(70 pieces, 94%) showed higher rate than that of clinical theses(4 pieces, 5%) in oriental medical studies. However, in medical studies, clinical theses(34 pieces, 68%) showed higher rate than that of experimental theses(15 pieces, 30%). 3. Analyzed by subject, the most dealt subject in oriental medicine was herb medication, followed by herbal acupuncture, single herb, electroacupuncture, sasang & gene, acupuncture & moxibustion, complex accordingly. The most dealt subject in medical clinical journals was standards of diagnosis & prognosis, followed by medication, gene analysis, pathogenesis, clinical pattern, operative treatment and complication accordingly. 4. In theses related to herb medication, most of the subject was to evaluate anti-inflammatory and immunoregulatory effects of herb medication with geopungseup, jibitong, hwalhyeolgeoer function. The tendency of experimental methods was focusing on understanding anti-inflammatory and immunoregulatory mechanisms through molecular biologic methods by analyzing cytokine and gene. 5. Most of theses related to herbal acupuncture were experimental studies verifying ant-inflammatory and immnoregulatory effects through methods observing change of cytokine and immunoregulatory factors. Regarding remedies for herbal acupuncture, Ulmus davidiana Planch was most preferred, followed by bee venom. 6. In theses related to single herb, Boik-yak was most prefered, followed by Geopungseup-yak and Hwalhyeolgeoer-yak. Regarding methods of research, there were tendency of shifting from methods verifying travail, anti-inflammatory and anti-pyretic effects through a test of behavior, morphometry, serology and temperature measurement of the rectum and the skin into verifying anti-inflammatory and immunoregulatory effects through observing inflammatory cytokine in the joint and cells of spleen. 7. In theses related to electroacupuncture, ST36 and adjuvant were most preferred as acupoints and induced factor. The tendency of experimental methods was turning from verifying mechanism of travail effect to analyzing inflammation and pain inducing factors. 8. Diverse medical clinical studies were published. Subjects such as diagnosis and prognosis, medication, gene analysis, clinical pattern, operational treatment, complication and pathogenesis were published. Especially, studies about standards of early diagnosis, and research on possible parallel medications with methotrexate were actively inquired. 9. Most of theses related to medical experimental studies was about mediators and receptors related to inflammatory induction and osteoclasia mechanism. Also, it was presented blockage of them can be effective on rheumatoid arthritis. Conclusions : The oriental medicine studies have merit in its diversity of treatment, but it clinical studies is lacking compared to experimental studies. Also, more diversity of subjects is necessary. Therefore, complementary measures are needed. Hereafter, oriental medicine research about rheumatoid arthritis needs more clinical research verifying the effectiveness and safety in clinical field. Also, we require oriental medical standard of diagnosis and researches on pathological generation which would make early checkup and prognosis possible.

The purpose of this study was to investigate the immunomodulatory effects of Alpina officinarum (AO) ethanol extract on immunocompromised mice. The mice were injected intraperitoneally with an immunosuppressive drug, cyclophosphamide, and then administrated orally with 30, 100, and 300 mg/kg of ethanol extract of AO (AO 30, AO 100, and AO 300, respectively). The concentrations of cytokines and immunoglobulins (IgM, IgA, IgG) in serum were measured. The body weight of the mice and spleen cell number of the AO-fed group showed no significant difference compared to a control group. The concentrations of several cytokines, including IL-2, IFN-${\gamma}$, and TGF-${\beta}$, in serum showed a significant increase in the AO 100 group compared to the control and other groups (p<0.05). The IL-4 level showed no significant difference in the experimental groups. The supplementation of AO (30, 100, 300 mg/kg) significantly increased the concentration of IgM (p<0.05). The concentration of IgA was significantly increased in the AO 100 group (p<0.05) compared to the control group. It can be concluded that AO ethanol extract enhances immune function by promoting the production of cytokines and immunoglobulins.

The purpose of this study evaluated the immunoregulatory effect of phellinus linteus ethanol (PLE) extracts on liver damage on carbon tetrachloride ($CCl_4$) induced in rats. Four-week old Male Sprague-Dawley rats were divided into the three experimental groups randomly; Control group, $CCl_4$ group, $CCl_4$ + PLE group. We found that effect of PLE on $IFN-\gamma$, STAT1 and pSTAT1 was decrease in vivo. Several genes were demonstrated to be IL-4 inducible prior to the discovery of STAT6. IL-4, STAT6 and pSTAT6 decreased significantly lower in $CCl_4$ + PLE than the $CCl_4$ group. Our data indicated that cytokine protein production were increased in $CCl_4$ group with $CCl_4$ + PLE group. In our data indicate that IgA levels in MLN lymphocytes were low, while IgE was high in $CCl_4$ + PLE group compared with $CCl_4$ group. Therefore, the results of this study show that PLE can be proposed to protect the liver against $CCl_4$-induced immunoregulatory activity in rats.

Background: Corticotropin-Releasing Hormone (CRH), an important regulator of stress response, has a potent immunoregulatory effect with the ability to promote the growth of various cancer through CRH receptor type 1 under stress. Although the metastasized cancers through cell migration are more aggressive than the primary cancers, little is known about the effect of CRH on cell migration. Gastric cancer is prone to metastasize to other tissues and it is reported that gastric cancer is response to various stresses such as oxidative stress. Herein, we studied the relationship between CRH and gastric cancer cell migration. Methods: We used gastric cancer cell line, MKN-28 and tested the CRH receptor type 1 expression on MKN-28 by RT-PCR. To examine the change in the ability of migration by CRH in MKN-28, cells were incubated with CRH and then migration ability was measured using a cell migration assay. Results: We confirmed that CRH receptor type 1 was expressed in MKN-28 and HaCaT cells. The migration ability of MKN-28 cells was increased by CRH in a time-, dose- dependent manner. Conclusion: These data suggest that CRH increases migration ability in gastric cancer cell line and that CRH may be a critical regulator in the metastasis of gastric cancer cell.

Although pathogenesis of human rheumatoid arthritis (RA) remains unclear, arthritogenic T cells and downstream signaling mediators have been shown to play critical roles. An increasing numbers of therapeutic options have been added for the effective control of RA. Nevertheless, there is still a category of patients that fails treatment and suffers from progressive disease. The recently developed immunosuppressant CP-690550, a small molecule JAK kinase inhibitor, has been implicated as an important candidate treatment modality for autoimmune arthritis. In this study, we evaluated the therapeutic effect of CP-690550 on established arthritis using an SKG arthritis model, a pathophysiologically relevant animal model for human RA. CP-690550 treatment revealed remarkable long-term suppressive effects on SKG arthritis when administered to the well-advanced disease (clinical score 3.5~4.0). The treatment effect lasted at least 3 more weeks after cessation of drug infusion, and suppression of disease was correlated with the reduced pro-inflammatory cytokines, including IL-17, IFN-${\gamma}$, and IL-6 and increased level of immunoregulatory IL-10.
