Zingiberis rhizoma(ZB) has been used to treat a various condition and disease in traditional oriental medicine. The present study was conducted to evaluate the immunomodulatory effect of aqueous-extracted ZB(ZBE) on methotrexate (MTX)-induced immune suppression in mouse spleen cells. In spleen cell proliferation assay, ZBE enhanced mitogenic activity in mouse spleen cells. In RT-PCR, ZBE induced IL-2, IFNr and IL-6 cytokine gene expression in mouse spleen cells. In spite of MTX treatment, IL-2, IFNr and IL-6 gene expressions sustained in MTX treated spleen cells. CD45R/B220, pan B marker was slightly increased in ZBE treated mouse spleen cells. IL-6, B cell tropical cytokine, production was induced by ZBE-treated mouse spleen cells and IL-6 production was sustained on MTX-ZBE co-cultured cells. ZBE administration enhanced suNival of S-180 bearing mouse. These data indicate that ZBE has a protective effect of immune suppression caused by MTX, and ZBE may be enhance cellular and humoral function by regulate cytokine gene expression as well as the mitogenic effect on spleen cells.

Balb/c mouse spleen cells in vitro sensitized against ICR spleen cells were cultured in conditioned media(CM). The CM was produced by ICR spleen cells stimulated with Concanavalin-A(Con-A), and sensitized lymphoid cells were grown in CM. ICR mouse spleen cells were appeared to be a good generator of IL-2. Optimal growth was seen in growth medium containing 20% fetal calf serum. and 25% CM. When cultures were initiated at 1, 5, $10{\times}10^4\;cells/ml$, the cells were increased in numbers by about 20, 13, 5-fold, respectively, every 9 days. Such growth pattern was sustained for about 4-6 weeks and thereafter the cell growth was diminished gradually. Direct immunofluorescence indicated that 93% of the lymphoid cells grown in CM(for 10 days) expressed Thyl surface antigen. And the cells grown in CM were cytotoxic to the sesitizing ICR mouse spleen cells though cytotoxicity level was not high. According to these results, the cells grown in CM were considered to be cytotoxic T lymphocytes. The lymphoid cells grown for 20 days were nearly unresponsive to Con-A and therefore dependent only IL-2 to be used for IL-2 assay.

This study deals with the biological changes in mice after ${\gamma}-irradiated$. Four weeks old BALA/c mice were irradiated with 6.5Gy of ${\gamma}-ray$ on the fifth day after oral administration of radioprotectants such as ascorbic acid, tocopherol and cysteine. Control group was irradiated with 6.5Gy without pre-administration of radioprotectors. Blood cells and sperm cells were counted and body, testis and spleen were weighed 3 days after irradiation. And also liver antioxidant activity and range of spleen immune cells were measured. Differences in most biological parameters were not clearly distinguished between experimental groups. However, the relative spleen weight, the relative testis weight and the population size of spleen immune cells such as T helper cells, B cells and macrophages measured by means of FACS showed significant difference between irradiated and radioprotectant administered group. It is concluded that the relative spleen weight, the relative testis weight and the population size of spleen immune cells are easy and useful parameters for assessing the effect of radioprotective substances and for quantifying biological damage of radiation, as well.

The effects of antlers have long been known in traditional Asian medicine. However, few studies have investigated the effects of antlers on immunity. In this study, we investigated whether fermented antler extract (FAE) has immunomodulatory effects on spleen cells. FAE enhanced the activity of spleen cells in a concentration dependent manner compared to antler extract. Interestingly, FAE significantly increased the production of interleukin-12, a representative cytokine of cell-mediated immunity, while it marginally increased that of tumor necrosis factor-alpha. Flow cytometry analysis demonstrated that FAE can protect spleen cells from spontaneous cell death without a significant proportional change in subsets, mainly lymphocytes. Taken together, the results of the present study showed that FAE has beneficial effects on spleen cells, a major type of immune cell, indicating that it can function as an immunomodulator without significant cytotoxicity. These data may broaden the use of FAE in basic research and clinical areas.

Mycobacterial cell-wall skeleton (CWS) is an immunoactive and biodegradable particulate adjuvant and has been tried to use for immunotherapy. The CWS of Mycobacterium bovis bacillus Calmette-Guerin (BCG-CWS) was studied as an universal vaccine vehicle for antigen conjugation, to develop potentially effective and safe vaccine. Although a variety of biological activities of BCG-CWS have been studied, the effects of BCG-CWS on spleen cells are not fully elucidated. Using MTT assay and trypan blue exclusion test, we found that BCG-CWS significantly enhanced the viability and proliferation of cells. Multiple clusters, indicating proliferation, were observed in BCG-CWS-treated spleen cells and surface marker staining assay revealed that BCG-CWS promoted the proliferation of $CD19^+$ B lymphocyte rather than $CD4^+$ or $CD8^+$ T lymphocyte. In addition, BCG-CWS up-regulated the expression of anti-apoptotic molecules such as bcl-2, bcl-xL. BCG-CWS increased the surface expression of CD25 and CD69 as well as IL-2 production of spleen cells, suggesting increased activation. Furthermore, BCG-CWS enhanced the antigen-specific cell proliferation and interferon-gamma production of spleen cells. Taken together, these results demonstrate the immunostimulatory effects of BCG-CWS on spleen cells via multiple mechanisms, providing valuable information to broaden the use of BCG-CWS in clinical and research settings.
