        Disulfiram is a drug used to treat alcohol dependence. Recent studies have shown that disulfiram also has anti-cancer effects. Considering that many anti-cancer agents have side effects, including immunosuppression, it is important to check if disulfiram has some cytotoxicity to immune cells. In this study, mouse spleen cells were treated with disulfiram and the metabolic activity was measured. Disulfiram increased the cell death of spleen cells according to annexin V-FITC/PI staining analysis. In addition, disulfiram decreased the mitochondrial membrane potential of spleen cells. The toxicity of disulfiram was concentration dependent. Interestingly, disulfiram affected the population of lymphocytes and the subset of spleen cells was altered. This study provides clinicians and researchers with valuable information regarding the toxicity of disulfiram to mouse spleen cells, particularly lymphocytes.

        Doxorubicin has been used to treating cancers, including breast cancer, bladder cancer, and acute lymphocytic leukemia, however, few studies have investigated its anti-inflammatory activity. In this study, we used mouse spleen cells treated with lipopolysaccharide (LPS), a representative inflammatory agent to investigate the effects of doxorubicin. Specially, we investigated the effects of doxorubicin on metabolic activity, cell size, cell death, and cytokine production of LPS-treated spleen cells. Doxorubicin significantly decreased the metabolic activity, even when applied at relatively low concentrations (1.6-8 ng/mL). To investigate the potential mechanism, we measured the mitochondrial membrane potential (MMP) of the LPS-treated spleen cells using Rhodamine 123. Doxorubicin decreased MMP and cell size, and induced cell death. Furthermore, doxorubicin suppressed the production of tumor necrosis factor (TNF)-alpha, a representative cytokine, in LPS-treated spleen cells. Taken together, doxorubicin decreased metabolic activity and the production of inflammatory cytokines, while increasing the death of LPS-induced hyperactivated spleen cells. This results will enable broader application of doxorubicin, as an anti-inflammatory agent, in clinical and research fields.

        King oyster mushroom (Pleurotus eryngii), an improved species of oyster mushroom, is a popular ingredient in Asian cuisine. Spleen cells were treated with various concentrations (0, 5, 10, 50, 100, 250, 500, and 1,000 μg/mL) of king oyster water extracts (KOWE); then, the proliferation of the cells was measured 24, 48, and 72 h after each treatment. Also, type 1 T helper cytokine productions (TNF-α, IFN-γ, and IL-2) were measured in activated macrophage by KOWE in seven concentrations. Under the condition of its 50, 100, 250, and 1,000 μg/mL for 48 h, the proliferation of cells was increased. However, there was no significant fluctuation in the spleen cells proliferation for 24 and 72 h-long KOWE exposure. To determine cytokine (TNF-α, IFN-γ, IL-2) productions of type 1 T helper cells, macrophage was stimulated by KOWE for 48 h. Treatment of KOWE gave a rise to the levels of TNF-α and IFN-γ, but not in that of IL-2 productions. These results suggest that king oyster mushroom water extracts may be beneficial for enhancing immune functions in its high concentration.

        Plantago asiatica L., observed frequently in East Asia, is a known herb used in traditional medical remedies several studies report that P. asiatica L has anti-inflammatory and antioxidant effects. To determine the production of cytokines (IL-2, IFN-γ, and TNF-α) induced by lipopolysaccharide (LPS) and non-LPS-stimulated macrophages, an ELISA assay was conducted using cytokine kits. Mice splenocytes were cultured for 48 h with various concentrations of P. asiatica L. (5, 10, 50, 100, 250, 500, and 1,000 μg/mL) or with mitogens (ConA or LPS). P. asiatica L. increased the proliferation of mice splenocytes, especially under the condition of its concentration ranging from 250 to 1,000 μg/mL. In addition, Plantago asiatica L. notably induced cytokine production of (IL-2, IFN-γ, and TNF-α) at its concentration of 250~500 μg/mL. These results suggest that supplementation with P. asiatica L. water extracts may play a potential role in enhancing immune function by mediating splenocyte proliferation and cytokine production through its anti-inflammatory activit.

        Fucoidan is a sulfated polysaccharide, purified from brown algae. It has multiple biological activities including anti-cancer and anti-inflammatory effects. Our previous reports demonstrated that fucoidan can stimulate spleen cells and especially high molecular weight fucoidan is responsible for the immunostimulatory activity. However, we recently found that the activity of fucoidan can be dependent on its individual batch or sources. Four different fucoidans (fucoidan A, fucoidan B, high molecular weight fucoidan, and low molecular weight fucoidan) were used for this study. MTT assay and flow cytometry analysis were performed for analysis of the activity of fucoidan. MTT assay showed that fucoidan B significantly decreased the cellular activity of spleen cells compared to fucoidan A. In addition, fucoidan B consistently killed spleen cells based on the cell size by flow cytometry analysis and the morphology by an inverted microscope. To elucidate the detailed mechanisms of cytotoxicity, fucoidan B-treated spleen cells were stained with Rhodamine 123 solution and Annexin V-FITC/propidium iodide for measurement of mitochondrial membrane potential (MMP) and early/late apoptosis, respectively. From these two assays, fucoidan B decreased the MMP and induced early apoptosis of spleen cells. Taken together, we suggest that different batches or origin of fucoidan may have differential activities on spleen cells, immunostimulatory and cytotoxic activity. The present study may provide some valuable information regarding use of fucoidan in the clinical area and in basic research.

        Taxol is an anti-cancer agent that stabilizes the microtubules of cancer cells, resulting in inhibition of mitosis and thus preventing the proliferation of cancer cells. However, many anti-cancer agents including taxol work on normal cells as well as cancer cells, resulting in side effects such as immunosuppression. A marine algae-derived sulfated polysaccharide, fucoidan, an anti-cancer agent, also showed immunostimulating effects. This study investigated the effects of fucoidan on taxol-treated spleen cells. Spleen cells were treated with taxol in a concentration-dependent manner and in combination with fucoidan. MTT assay and flow cytometry analysis were performed to measure the viability and activity of treated cells. Two assays demonstrated that taxol induced the death of spleen cells. Fucoidan clearly inhibited the cell death induced by taxol. In addition, fucoidan enhanced the production of nitric oxide in spleen cells, which was decreased by taxol. Taken together, taxol can induce the cell death of spleen cells, a major type of immune cells and fucoidan protects spleen cells from taxol-induced cell death. This finding suggests that taxol and fucoidan can be used in combination for lowering the immunosuppressive effects of taxol.

        부비장은 정상인의 약 10%에서 발견되고 약 16%에서 췌장에서 발견되는 것으로 알려져 있다. 그러나 췌장 내의 부비장에서 발생한 유표피 낭종은 극히 드물고 특이적 방사선 소견이 없어 진단하기 매우 어려워 췌장의 낭성 종양으로 오진하기 쉽다. 저자들은 우연히 발견된 췌장 미부의 낭성 종괴에 췌장 낭성 종양 의심하에 원위부 췌장절제술을 시행하였으나 수술 후 병리학적인 검사상 췌장 내 부비장에서 발생한 유표 피 낭종으로 진단된 증례를 2예를 경험하였기에 문헌고찰 과 함께 보고하는 바이다. 췌장 내 부비장의 유표피 낭종은 영상학적인 검사나 임상양상을 통해서는 다른 췌장의 낭성 종양과 쉽게 구분할 수가 없으며 따라서 췌장 낭성 종양에 대한 감별진단으로 췌장 내 부비장의 유표피 낭종의 가능성도 고려가 필요하겠다.

        Mycoplasma hyopneumoniae (M. hyopneumoniae) is one of the causative bacteria that can induce chronic enzootic pneumonia, resulting in low production in the swine industry. Potentiation of porcine reproductive and respiratory syndrome virus-induced pneumonia by M. hyopneumoniae has also been recognized. Although some available vaccines have been developed for prevention of M. hyopneumoniae infection, protective immunity is still poor. In this study, in order to provide valuable information on vaccine antigen, we investigated the immunogenicity of M. hyopneumoniae on mouse spleen cells. Concanavalin A (ConA) and lipopolysaccharide (LPS) were used for generation of activated T and B lymphocytes. M. hyopneumoniae made clusters of spleen cells and also affected the cellular activity and viability of spleen cells by alone or with mitogens. Of particular interest, it induced a significant increase in production of TNF-alpha in ConA- treated spleen cells, meaning T helper 1 response. In addition, cell size and mitochondrial membrane potential of M. hyopneumoniae–treated spleen cells were measured by flow cytometric analysis. M. hyopneumoniae did not affect the cell size by alone, whereas ConA or LPS profoundly increased the cell size. Taken together, M. hyopneumoniae significantly affect the cellular activity and cytokine production of spleen cells by alone or in a combination of ConA. This study provides valuable information for production of the vaccine against M. hyopneumoniae.

        Dang, jonghae had written five books on chinese medicine, 『Hyeoljeungron』 is his most important work. He wanted to correct the fallacies of the theory of Jang(臟) and Bu(腑) by comparing with chinese and western medicine. He distinguished Bi(脾) from Cheomyuk(甛肉) by comparing the spleen with the pancreas. He recognized Stomach as the warehouse of foods, and explained that Bi took charge of digestion actually. Bi charged the function of Transportation(運化) and Blood-govering(統血) in addition to plain digestion, he wrote. Dang, jonghae regarded the metabolism of the human body as the interaction of Gi(氣), Blood (血), Water(水) and Fire(火). And he explained that Bi adjusted them. He classified Syndrome of Blood(血證) into five sorts of syndrome and presented four kinds of treatment. Especially he took a serious view of the treatment connected with Bi and Stomach. He set up the theory of Bi and Stomach(脾胃論) practically on basis of anatomy, but he didn't assorted the physiology and pathology of each organ clearly. However he proved the importance of Bi and Stomach by treating Syndrome of Blood and provided with the foundation of merging chinese and western medicine.
