Immunosuppressive therapy after organ transplantation is routinely used to prevent rejection of the organ, because this decreases the risk of adverse events, infection, and malignancies. Recently, ursodeoxycholic acid (UDCA), which is isolated from the dried bile of adult Chinese bears, has been shown to reduce the incidence and severity of acute rejection of liver allograft during early phase of liver transplantation. Therefore, in this study, we investigated the effect of UDCA on the proliferation of splenocytes exposed to PMA plus ionomycin. Our results demonstrated that UDCA decreased the splenocytes' proliferation in a dose-dependent manner. The decreased cell proliferation was accompanied with the decreased secretion of cytokines such as IL-2, IFN-${\gamma}$ and TNF-${\alpha}$. In addition, the pretreatment of UDCA on splenocytes stimulated with PMA plus ionomycin decreased the mRNA levels of cytokines (IL-2, IFN-${\gamma}$ and TNF-${\alpha}$) and costimulatory molecules (B7.2 and PD-L1). These results suggest the beneficial effect of UDCA on organ transplantation by decreasing lymphocyte proliferation.

The purpose of this study is to prove the efficacy of KamiBohuh-tang(KBT) on immunoregulation and the possibility of KBT as an immunoadjuvant. KBT with solid feed was administered orally once a day for 7 days to an experimental group, a solution of salt and solid feed without KBT to a control group. After a week T cell, B cell, cytokines, nitric oxide and phagocytic activity are measured. KBT enhanced the proliferation of splenocytes and the subpopulation of Th cells in splenic T-Iymphocytes, but did not affect the proliferation of thymocytes. KBT decreased the subpopulation of T-Iymphocytes in splenocytes. KBT enhanced the production of interferon-γ. interleukin-2, interleukin-4 in mice serum and the phagocytic activity in peritoneal macrophages but it suppressed the production of nitric oxide. These results suggest that KBT is a potent prescription on immune response via the increase of the proliferation of splenocytes, the production of cytokines from splenic Th cells and the phagocytic activity in vivo.

Sunjeonhwadok-Tang was a drug that treated carbuncle and cellulitis. So, the purpose of this study was to investigate effects of Sunjeonhwadok-Tang on the proliferation of cancer calls and immunocytes focusing around combined effects of anticarcinogen. We used Sunjeonhwadok-Tang extract(SHT) with freeze-dried, 8wks-old male balb/c mice and cancer cell lines(L1210, Sarcoma-180) for this Study. The proliferation of cells was tested using a colorimetric tetrazoliun assay(MTT assay). The results : 1. SHT was significantly showed cytotoxicity on the L1210 cell lines. 2. SHT was significantly increased proliferation of thymocytes and splenocytes in vitro. 3. In combined effects of SHT and vincristine(0.005 mg/kg), SHT was significantly inhibited proliferation of L1210 cell lines, but was not inhibited proliferation of Sarcoma-180 cell lines compared with positive control group. 4. In combined effects of SHT and vincristine(0.005 mg/kg), SHT was significantly increased proliferation of thymocytes and splenocytes compared with positive control group. 5. In combined effects of SHT and vincristine, SHT was significantly increased proliferation of thymocytes and splenocytes in normal mice. 6. In combined effects of SHT and vincristine, SHT was significantly inhibited proliferation of L1210 cells in L1210 cells transplanted mice 7. In combined effects of SHT and vincristine, SHT was significantly increased proliferation of L1210 cell in L1210 cells transplanted mice. The present author thought that SHT had action of anti-cancer and immuno-activity, and in combined effects of vincristine, SHT had recoverable effects on damage by anticarcinogen.

Recently many investigators have initiated searches for immunomodulating substances from natural food sources. Ginger (Zingiber officinale Roscoe) has been used as a raw material in many traditional preparations since the ancient time. This study was performed to investigate the immunomodulative effects of Zingiber officinale Roscoe in mice, using ex vivo experiments. In order to elucidate the immunomodulative effects of Ginger, water extracts of the plant were orally administrated into mice, and isolated splenocytes and macrophages were used as experimental model. In order to identify its ex vivo effect six to seven week old Balb/c mice were fed ad libitum on a chow diet and water extracts of ginger were orally administrated every other day for two weeks at two different concentrations (50 and 500 mg/kg b.w.). After preparing the single cell suspension, the proliferation of splenocytes was determined by MTT assay. The result of ex vivo study showed that the highest proliferation of splenocytes and macrophage activatation was seen in the mice orally administrated at the concentration of 500 mg/kg b. w. of ginger water extracts. In conclusion, this study suggests that ginger extracts nay enhance the immune function by regulating the splenocyte proliferation and cytokine prodution capacity by activated macrophages in mice.

Pumpkin sweet potato (Ipomoea batas L.) has been known as a traditional remedy and food source, not only in South Korea but worldwide. It is rich in fiber, potassium, vitamin C, and other minerals and vitamins, making it a nutritional food loved by many. showed that pumpkin sweet potato had antioxidant biological effects. The in vitro study showed that both splenocytes and cytokine production byactivated peritoneal macrophages increased when water extracts were supplemented at 100 and 250 μL/mL. Notably, the production of IL-1β, TNF-α, and IFN-γ by splenocytes was significantly increased at 100 μL/mL. The results suggest that supplementation with pumpkin sweet potato (Ipomoea batas L.) water extract may enhance immune function by stimulating splenocyte proliferation and improving cytokine production, activating macrophages in vitro.
