Objectives : The aim of this study was to investigate the immunopotentiating activity of combine extract that Silkworm and Cinnamomum cassia. Recently, acute epidemic diseases such as cold and viral respiratory diseases have been emerging. So, interested in immunity enhancement has been increasing, and research on natural products to promote immunity activity has been actively conducted. Methods : To confirm the immunopotentiating activity effect, Silkworm (SW), Cinnamomum cassia (CC), and SWCC combined extracts were treated 14 days at 300 mg/kg/day. The changes of glutamic oxalacetic transaminase (GOT), glutamic pyruvate transaminase (GPT) in serum were analyzed after experiment. The changes in the total spleen cell number were measured. Immune cells in spleen were analyzed using fluorescence activated cell sorter (FACS). also, analyzed the expression of cytokines in spleen. Results : Total number of cells in the spleen and FACS analysis of T lymphocytes activated in the spleen showed that the SWCC combined treated group had much higher frequency of active cells than both single groups. The ratio of CD4+CD8+, CD4+CD69+ and CD4+CD25+ T cells in spleen, SWCC is higher than other groups except Nor in CD4+, CD4+CD69+, CD4+CD25+ T cells. The results of this study suggest that SWCC can help immune function via IL-2, IL-10, IL-12, IFN-${\gamma}$ cytokine production, increased T lymphocytes and splenocyte proliferation. Conclusion : Therefore, these results suggested that the SWCC combined extracts administration increase stronger immunity enhancement than when SW and CC adminstration.

The studies were conducted to investigate the combined effects of several combined preparation of crude drugs and mitomycin C(MMC). The combined effects on the proliferation of HepG2, A549, KHOS-Np, A431 and HeLa cells were estimated by MTT colorimetric assays. Sa Kunja Tang(SKT), Boyang Hwanoh Tang(BHT) and Hyulbu Choogo Tang(HCT) inhibited the proliferation of A549 and HeLa cell. The inhibitory action of MMC was increased by the combined treatment of SKT and MMC, and Sa Mul Tang(SMT) and MMC, respectively. When the mice were treated by MMC, the number of leukocyte was decreased significantly at the 3rd day, but recovered at the 7th day. In the groups of MMC treated with SKT or HCT, the number of leukocyte was increased significantly that the group of MMC treated only at the 1st and 3rd day. The combined treatment of SKT, SMT, BHT, HCT and MMC retained the spleen weight of mice at the level of normal mice, but decreased the thymus weight of mice. The combined treatment of SKT, SMT, BHT, HCT and MMC increased the number of PFC significantly than the MMC treated group. The combined treatment of SKT, SMT, BHT, HCT and MMC increased the T cell proliferation significantly thant the MMC treated group.

Taurine (2-ethaneaminosulfonic acid, $^+{NH}_3{CH_2}{CH_2}{SO_3^{-}}$) is endogenous amino acid with functions as modulator of osmoregulation, antioxidation, detoxification, transmembrane calcium transport, and a free radical scavenger in mammalian tissues. Taurine transporter(TAUT) contains 12 transmembrane helices, which are typical of the $Na^+$- and $Cl^-$-dependent transporter gene family, and has been cloned recently from several species and tissues. To analyze the expression of TAUT mRNA, one step RT-PCR was performed from human and mouse cultured cell lines and from various mouse tissues. The primers were designed to encode highly conserved amino acid sequences at the second transmembrane domain and at the fourth and fifth intracellular domains. RT-PCR analysis showed both of the human intestine HT-29 and mouse macrophage RAW264.7 cell lines expressed mRNA of TAUT. To define the expression patterns of the TAUT mRNA in the murine organs, RT-PCR was performed to detect cDNA representing TAUT mRNA from seven different mouse tissues. The TAUT was detected in all of the mouse tissues analyzed such as heart, lung, thymus, kidney, liver, spleen and brain. A large amount of transcript was fecund from heart, liver, spleen, kidney, and brain, while lung contained a very small amount of transcript.

Objectives : The purpose of this study is to investigate cisplatin-induced apoptosis by ethanol extract of bojungbangam-tang (EBJT). Methods : To evaluate of anti-apoptic effects of EBJT, we examined several kinds of cell populations such as $CD4^{+}$ T cells, $CD8^{+}$ T cells and macrophages in spleen. Result : 1. EBJT inhibited cisplatin-induced cell death in spleen. 2. EBJT inhibited the death of $CD4^{+}$ and $CD8^{+}$ T cells. 3. EBJT slightly recovered the number of macrophages by cisplatin. Furthermore, cisplatin-induced upregulation of class II were inhibited by EBJT. Conclusion : EBJT prevented cisplatin-induced cell death, which could provide a clinical basic for side effects of anti-tumor therapeutics.

The purpose of this research was to investigate the effect of reaction-precipitate from Coptidis Rhizoma and Glycyrrhizae Radix aqueous mixture(CGP) on the cytotoxicity. The effects of CGP on the growth of tumor cells, Balb/c 3T3 cell, mouse spleen cell and human lymphocyte were compared with those of berberine, glycyrrhizin and berberine glycyrrhizinate(BG), which were estimated by MTT colorimetric assay or cell counting. CGP, berberine and BG inhibited the growth of several tumor cells, such as Hep G2, A549, Raji, MCF-7, HeLa and KHOS-NP. Whereas, glycyrrhizin inhibited the growth of Raji and MCF-7, CGP did not affect on Balb/C 3T3 cells, mouse spleen cells and human lymphocyte at $10^{-6}{\sim}10^{-5}g/ml$. CGP increased the number of leukocyte in mice. This results indicate that CGP have the inhibitory action of the growth of human tumor cells, and the side effect of CGP is less than berberine and BG.

In order to investigate the immunostimulating effect of mycelia extract of Phellinus linteus (PLM) on human monocyte THP-1 and rat peritoneal macrophage cell, we examined measuring cytokine secretion (IL-6 and TNF-${\alpha}$). The production of IL-6 and TNF-a in human monocyte THP-1 was slight increased dose-dependently when the cells were challenged with PLM for 72 hrs. It was also observed that the treatment of PLM with LPS augmented the production of IL-6 and TNF-a in human monocyte THP-1. It was also observed that the treatment of PLM with LPS augmented the production of IL-6 and TNF-${\alpha}$ in human monocyte THP-1. The production of IL-6 and TNF-${\alpha}$ in rat peritoneal macrophage was significantly enhanced when the cells were treated PLM with LPS for 72 hrs. Moreover, the proliferation rate of rat spleen cells was increased in a dose dependent manner as the cells were treated with PLM and Concanavalin A.

A primary metastatic malignant plasma cell tumor was diagnosed in a 7-year-old, female mixed breed dog. The dog was admitted to Veterinary Teaching Hospital at College of Veterinary Medicine, Seoul National University after suffering from depression, anorexia, and dyspnea. In radiographic examination, a large occupying mass was found at the right cranial thorax. Due to poor prognosis, the dog was euthanized. At surgery, numerous, firm, round, nodules, 1 to 2 cm in diameter were noted in the ribs. The nodules were often confluent and had cylindrical appearance. Osteolysis was associated with the nodules. A large amount of clear fluid was present in the thoracic cavity. The spleen and liver were markedly enlarged and congested. Histologically, the mass was diagnosed as plasma cell tumor which was believed to be originate from the rib. Evidence of metastasis was observed in the spleen, liver, and kidney.

Objective : The aim is to examine the effect of Soyeum Pharmacopuncture (SPP) on collagen-induced arthritis (CIA) in DBA/1OlaHsd mice. Methods : To determine the effect of SPP on chronic IFNlammatory joint disease, we induced CIA in DBA/1OlaHsd mice by immunization with bovine type II collagen. Animals were treated with intraperitoneal injection doses of 2 mg/kg of SPP, beginning 3 days before the expected onset of disease symptoms. Inhibitory Effects of SPP were observed by serum levels of TNF-${\alpha}$, and IFN-${\gamma}$,,, or cell proliferation in the spleen cell culture and histological examination of knee joint. Results : In the CIA Mice, serum levels of TNF-${\alpha}$, and IFN-${\gamma}$,, production in the spleen cell culture were reduced. At the histopathological examination of knee joint, chondropathy of cartilage in the synovial joint in the SP group was repaired while compared with control group. Conclusion : These results suggest that the SPP may be effective for the prevention and treatment of rheumatoid arthritis disease.

In fish both humoral and cell mediated immune responses have been reported whereas antibodies recognizing specific cellular populations have not yet been developed except for ones recognizing surface Ig molecules on B lymphocytes. Our aim was to develop and characterize monoclonal antibodies (Mabs) specific for the immune-related cells. Mabs were produced by fusion of myeloma cells (SP2/0) with Balb/c mouse spleen cells previously sensitized against Israeli carp (I. carp) kidney mononuclear cells. We obtained 44 Mabs positively reacting with I. carp kidney mononuclear cells and partially characterized 7 Mabs in the morphological and mitogen-based proliferative aspects. Fluorescence-activated cell sorter (FACS) analysis against I. carp kidney cells by using 7 different Mabs showed 80.3% for ICK 17-4, 65.1% for ICK 2-3, 64.1% for ICK 25-1, 67.5% for lCK 22-1, 70.8% for ICK 16-2, 76.8% for ICK 13-2, 79.7% for ICK II-I. Panning method was used for the isolation of Mabs specific mononuclear carp spleen cells followed by Wright's stain. The stained cell populations were identified as monocytes (ICK 17-4, ICK 2-3, ICK 25-1, ICK 22-1 and ICK 16-2), lymphocytes (ICK 11-1), and a mixed cell population of monocytes and lymphocytes (ICK 13-2). In cell proliferation assay, monocytes purified by ICK 17-4, 2-3 and 22-1 efficiently responded to Con A and PHA, while ones separated by ICK 25-1 did not react with any mitogens. Lymphocytes isolated by ICK 11-1, though it is not known whether they are T or B cells, were more responsive to Con A than PHA or LPS, suggesting that fish immune cells are somewhat different from mammalian cells in responding to mammalian T or B cell mitogens.
