This study investigated the clinical parameters of atopic dermatitis and evaluated the inhibitory effects of Black currant seed oil for atopic dermatitis by using a Dinitrochlorobenzene(DNCB) induced BALB/c mice model. Five-week-old BALB/c mice were divided into four groups: normal group (N, non-treated), control group (C, atopic dermatitis-induced), positive control group (PC, Tacrolimus ointment-treated against induced atopic dermatitis, PC), experiment group (E, Black currant seed oil-treated against induced atopic dermatitis). After induction of atopic dermatitis by DNCB, the erythema, edema, eschar, and scratching were severely observed. The symptoms of atopic dermatitis were improved after 2 weeks, and almost disappeared after 4 weeks in PC and E group. The increased frequencies of scratching in C group were decreased in PC and E group. Transepidermal water loss, erythema index and serum IgE level were significantly decreased in E and PC compared to that in C after 4 weeks of the treatment. The results indicated that Black currant seed oil can relieve atopic dermatitis symptoms effectively, and may be possibly used as a functional material for suppression of atopic dermatitis.

Trichomoniasis is a common sexually transmitted infection caused by Trichomonas vaginalis, which actually does not exist a vaccine for control or prevention. Thus, the identification of new and potent immunogens in T. vaginalis, which can contribute to the development of a vaccine against this parasite, is necessary. Therefore, the aim of this work was to evaluate the potential of a recombinant Transient Receptor Potential-like channel of T. vaginalis (TvTRPV), as a promising immunogen in BALB/c mice. First, TvTRPV was cloned and expressed as a recombinant protein in Escherichia coli BL21 cells and purified by nickel affinity. Next, BALB/c mice were immunized and the antibody levels in mice serum and cytokines from the supernatant of macrophages and from co-culture systems were evaluated. Recombinant TvTRPV triggered high levels of specific total IgG in sera from the immunized mice. Also, a statistically significant increase of cytokines: $IL-1{\beta}$, IL-6, and $TNF-{\alpha}$ after stimulation with the corresponding antigens in vitro, was identified. Moreover, co-cultures using $CD4^+$ T cells from immunized mice were able to identify higher levels of IL-10 and $IFN-{\gamma}$. These results were useful to validate the immunogenicity of TvTRPV in BALB/c mice, where IL-10-$IFN-{\gamma}$-secreting cells could play a role in infection control, supporting the potential of TvTRPV as a promising target for vaccine against T. vaginalis.

The purpose of this research was to investigate effect of water extract of DangKwi-Eum-Ja ka Sumsoo(DESE) on the cytotoxicity of human epidemloid cell, A431 cells. The effects of DESE on the proliferation of A431 cells, Balb/c 3T3 cells, mouse thymocytes and splenocnes were estimated by MTT colorimetric assay, and nitric oxide production from mouse peritoneal macrophage was estimated by Griess method. DESE inhibited the proliferation of A431 cells at $10{\mu}g/ml$, and did not affect the proliferation of Balb/c 3T3 cells. DESE decreased the cytotoxicity of mitomycin C or cisplatin on A431 cells, increased the cytotoxicity of mitomycin C or cisplatin on Balb/c 3T3 cells. DESE inhibited the proliferation of mouse thymocytes and splenocytes at $100{\mu}g/ml$. DESE did not affect the nitric oxide production from mouse peritoneal macrophage in vitro, but decreased the nitric oxide production from DESE-treated mouse peritoneal macrophage.

The purpose of this study was to investigate the immune activation effect of Sasamsaengmaek-san (SSSMS) consisted of a mixture of Adenophora triphylla var. japonica, Liriope platyphylla, Panax ginseng C. A. Meyer and Schisandra chinensis. in Balb/c mice. Measuring alanine aminotransferase (ALT) and aspartic acid transaminase (AST) levels in Balb/c mice was performed to analyze the cytotoxicity. Cytokines (IFN-γ, IL-2, IL-12) which regulate the immune activation in Balb/c mice were measured by enzyme-linked immunosorbent assay (ELISA). Activated T lymphocytes in peripheral blood mononuclear cell (PBMC), spleen, lymph nodes were analyzed by flow cytometry using percentages. All tests were compared with red ginseng 100 ㎍/mL (RG 100), which is the most used for immune activity. As a result, cytokine activity was significantly increased at SSSMS 300 group. Activated T lymphocytes in PBMC, spleen, lymph nodes were significantly increased at SSSMS 300 group. These results suggest that there is a possibility of SSSMS activating an immune system by activating the cytokines, and it is confirmed that SSSMS also effective for generation and differentiation of T, B lymphocytes which activate the immune response.

BALB/c 마우스에서 감염부위와 감염기간에 따른 숙주 체액 면역반응의 변화를 알아보고자 하였다. 배양한 큰리슈만편모충의 전편모형(promastigote)을 BALB/c 마우스의 코. 등 발바닥 부위로 나누어 각각 $3{\;}{\times}{\;}10^6$마리씩 피하 감염 후 10-100일 동안에 궤양의 형성과정을 관찰하고 채혈하여 SDS-PAGE와 면역이적법을 시행하여 각 부위별로 나타나는 항체 반응을 관찰하였다. 외관상으로는 감염 15일부터 코에 감염시킨 마우스에서 먼저 궤양이 형성되기 시작하였고. 코에 궤양이 나타난 후 2-3일 뒤에 발에서 궤양이 형성되었으며 등에서는 감염시킨 후 90일이 되어서야 궤양이 관찰되었다. 감염후 20일에 실시한 면역이적법에 의하면 코 감염군에서는 202, 139, 98, 83, 81, 67, 65, 62, 59, 54, 52, 42, 26, 23 kDa의 항원성 분획이 관찰되었고 발 감염군에서의 항원 분획양상도 코 감염군과 같았으나 등감염군에서는 202, 83, 81, 65 kDa의 희미한 항원성 분획이 관찰되었다. 그러나 감염 후 90일이 경과한 등 감염군에서는 202, 83, 81, 74, 67, 65, 62, 59, 54, 52, 20, 17 kDa의 항원 분획이 관찰되었다 이상의 결과로부터 감염부위와 감염기간에 따라 큰리슈만편모충에 대한 혈청반응이 항원 분획에 따라 다르게 나타남을 관찰하였다. 이 차이는 세 감염부위의 온도차에 의한 결과일 가능성도 있으나 다른 부위에 감염될 경우 한 숙주 내에서도 다른 면역반응이 유발되어 나타날 수도 있다고 추측하였다. 특히 궤양 형성 시기와 혈청 내 67-52 kDa 분획에 대한 항체 출현 시기가 일치하는 것으로 보아 궤양 형성에 이 항체가 관여할 가능성이 있음을 시사한다.

The purpose of this research was to investigate the effects of petroleum ether extract of Euonymus alatus (EAP) on the proliferation of human tumor cells. EAP inhibited the proliferation of HeLa, Hep G2, KHOS/NP and A431 cells. The cytotoxicity of doxorubicin on human tumor cells and Balb/c 3T3 cells were increased by the combination of EAP. EAP did not affect the proliferation of Balb/c 3T3 cells, mouse spleen cells and human lymphocytes. These results suggest that EAP has the cytotoxicity on human tumor cells without cytotoxicity on Balb/c 3T3 cells, mouse spleen cells and human lymphocytes, and increase the cytotoxicity of doxorubicin.

This study was performed to investigate antigenic expression patterns in the course of HSV-1 infection. In SDS-PAGE analysis, HSV-1 antigens were detected, and among them, antigens in the size of 39, 47, 63, 86, 101, 105, 135, 159, and 181 kDa appear to be expressed in the most dominant forms. BALB/c mice were infected with HSV-1 for 29 days and antigenic expression from HSV-1 was investigated by Western blot analysis using anti-HSV-1 sera collected every two days from BALB/c mice infected with HSV-1. Most of HSV-1 antigens appeared sporadically as the infection progressed. However, antigens in the sizes of 63kDa and 135kDa were expressed from day 1 and 3, respectively, and existed continuously during the course of infection for 29 days, suggesting that they are the most dominant antigens inducing immune response durign HSV-1 infection, and they could be the target antigens for the development of vaccines. The isotype levels of IgA, IgGl, and IgM increased till the 17 th day infection and then started to decrease. During this course. IgGl was the most dominant isotype. In an indirect immunofluorescent assay, antibodies exhibited surface binding to the Vero cell infected with HSV-1, demonstrating that HSV-1 antigens are expressed on the surface of Vero cells.

These experiments were conducted to investigate the effect of Taklee Hwangki Tang(THT) on inflammation. THT extract did not affected on the leakage of evans blue into peritoneal cavity and mouse paw edema induced by histamine, but decreased the cottom pellet granuloma formation. Using proliferation of Balb/c 3T3 fibroblast cell line as an in vitro model of granulation tissue formation, the ability of THT to stumulate cellular proliferation of fibroblast cells was investigated. When the cells were seeded at $1{\times}10^4$ cells/well, balb/c 3T3 cells are reached to the late expponential phase at 3rd day. Under the conditions established above, THT increased the proliferation of Balb/c 3T3 cells at concentration of $10^-,\;10^{-6}\;and\;10^{-5}g/ml$. The treatment of $10^{-6}g/ml$ of THT did not influence onthe NDA syntesis and proteinsynthesis of the cells. The $10\%$ serum from THT treated mice(500mg/kg/day for 4 days) increased the proliferation of Balb/c 3T3 fibroblast markedly, but decreased the DNA synthesis and protein sythesis of the cells. The results suggest that THT may be of practical therapeutic use at the period of the last in. flammation.

Atopic dermatitis (AD) is a common chronic inflammatory disease of preceding the development of allergic disorders. The incidence of AD is increasing and it causes problems with administrative costs. Therefore, no side effects, easyto- use development of AD treatment is needed. The aim of this study was to evaluate whether PBMCAT, a functional extract from herbal complex was effective to treat the AD mice. AD was induced by patching ovoalbumin on the backside in BALB/ c mouse and then mice were topically treated with PBMCAT. Elidel $cream^{(R)}$ (pimecrolimus, PL) was used as a control. Scratching counts (SC) and clinical skin severity (CSS) were measured, and total serum IgE level was also measured. After inducing AD, SC and CSS were increased. The total serum IgE level was also increased in AD-induced mice. Treatment with PBMCAT significantly decreased SC, CSS, and serum IgE concentration in mice. Especially, treatment of PBMCAT 0.1% in BALB/c mice more effected than PL. These results suggest that the ointment of PBMCAT may enhance the process of AD healing by influencing phase of allergic reacting.
