  • Objectives : The purpose of this study is to investigate the effect of Ulmi Cortex(UC) on the cisplatin-induced cell death. Materials and Methods : I examined several kinds of cell populations such as $CD4^+$ T cells, $CD8^+$ T cells, macrophages and dendritic cells in spleen. Result : When cisplatin was injected to mice, UC recovered total number of cells in spleen and also the number of T cells, macrophages and dendritic cells. UC also effected the activation of $CD4^+$ and $CD8^+$ T cells such as $CD25^+$, $CD69^+$ cells. To further investigate the effect of UC on the cisplatin-induced cell death, I examined the death of splenocyte and total T cells. UC inhibited cisplatin-induced cell death. Conclusion : Taken together, my results suggest that UC may be a beneficial oriental medicine for side effects during anti-tumor therapy.

  • Objectives: Three yin-tonifying formulae (Ssanghwa-tang, Yukmijihwang-tang and Jaeumganghwa-tang) were applied to investigate their immunological activities on antigen (Ag)-specific or Ag-non-specific immune responses in the murine macrophage cell line (RAW 264.7) and in ovalbumin (OVA)-immunized mice. Methods: This study was carried out in nitricoxide (NO) synthesis in RAW 264.7 cells and cellular proliferation in mouse splenocytes in association with three herbal formulas. C57BL/6 mice were immunized intraperitoneally with OVA/aluminum ($100\;{\mu}g/200\;{\mu}g$/mouse) on days 1, 8, and 15. Three herbal formulas were administrated to mice orally for 3 weeks from day 1. On day 22, OVA-, lipopolysaccharide (LPS)-, and concanavalin A (Con A)-stimulated splenocyte proliferation and antibodies (OVA-specific antibodies of the IgG, IgG1, and total IgM classes) in plasma were measured. Results: All three yin-tonifying formulas significantly enhanced cellular proliferation by LPS and Con A in splenocytes from OVA-immunized mice (p<0.001). Also, these herbal formulas all significantly enhanced plasma OVA-specific IgG, IgG1, and total IgM levels compared with the OVA/Alum group. Conclusion: These results suggested that the three yin-tonifying formulae could be used as stimulators of immune response.

  • Lactic acid bacteria (LABs) have been proposed as a potential oral allergy-therapeutic means of modulating immune phenotype expression in vivo, via promoting or reducing cytokine production. This study investigated the ability of LABs to suppress allergic response via modulating cytokine production in mice splenocytes. BALB/c mice were intraperitoneally primed with ovalbumin together with alum adjuvant to invoke antigen-specific Th1/Th2 cytokine-secreting cell populations in splenocytes. Spleen cells from mice fed with Lactobacillus confusus PL9001 (KCCM-10245), L. fermentum PL9005 (KCCM-10250), L. plantarum PL9011 (KCCM-10358), and Bifidobacterium infantis PL9506 (KCCM-10406) suppressed the levels of Th2 cell cytokines such as IL-4 and IL-5 during antigen sensitization. In addition, all mice fed with LABs induced secretion of Th1 cell cytokines such as IL-2 in splenocytes. These results suggested that LABs are anti-allergic agents, in view of their Th1/anti-Th2 immunoregulation.

  • Atopic dermatitis (AD) is a chronic inflammatory skin disease characterized by inflammatory cell infiltration in the skin. This study was performed to assess the therapeutic effects of YHYBT on the DNCB-induced dermatitis in NC/Nga mice, characterized by the onset of AD along with an increase the number of Th2 cells and dysregulation of inflammaroty mediators including cytokines and chemokines. YHYBT administration significantly reduced clinical dermatitis severity including pruritus, edema, eczematous and erythema. Histological findings indicated that the thickening of epidermis/dermis and dermal infiltration of inflammatory cells including mast cells were dramatically reduced. The suppression of dermatitis by YHYBT was accompanied by a decrease in the total number of immune cells in drained lymph node (DLN) and skin. Especially CD3+, CD4+ and CD3+CD69+ T cells in PBMC and DNL were greatly reduced. The level of IL-4 in CD3/CD28 activated splenocyte was downregulated, whereas that of IFN-'처리불가‘ was increased. Furthermore, the expression of eotaxin2 and CCR3 in skin were significanlty decreased. These data suggest that YHTBT may be effective therapeutic agents for the treatment of AD.

  • The present study was aimed to investigate the effects of MB12662, a synthetic dunnione compound, on cisplatin-induced vomiting reflexes and intestinal, renal, immune system, and hematopoietic toxicities in ferrets and mice, respectively. Male ICR mice were orally administered MB12662 (5, 10, 25 or 50 mg/kg) for 10 days, during which intraperitoneally challenged with cisplatin (3.5 mg/kg) from day 4 to 7, and sacrificed on day 10 for the pathological examination. Male ferrets were orally administered MB12662 (25, 50 or 100 mg/kg) for 7 days, subcutaneously challenged with cisplatin (5 mg/kg), and monitored for vomiting reflexes and survival of the animals. Four-day injection of cisplatin (3.5 mg/kg) to mice caused body weight loss and degeneration and atrophy of intestinal villi, reducing villi/crypt ratio to a half level of control animals. Cisplatin also induced renal and hepatic toxicities, and depletion of splenocytes and bone marrow progenitor cells. The systemic toxicities including decreased villi/crypt ratio, immune system atrophy, splenocyte depletion, and decreased cellularity in bone marrow were improved by MB12662. Cisplatin (5 mg/kg) induced retching and emetic responses of ferrets, which were remarkably attenuated by MB12662 in a dose-dependent manner. All the ferrets pretreated with MB12662 survived the challenge of cisplatin, in comparison with 40% mortality in vehicle-treated animals, and blood parameters of nephrotoxicity and hepatotoxicity were markedly recovered. It is expected that MB12662 could be a candidate for the body protection against burden, including emesis, of chemotherapeutic agents.

  • Multiple beneficial properties of Opuntia ficus indica (OPF) are well established. In the present study, we have investigated the immunological role of OPF extract (OPFE) on murine splenocytes. OPFE dose- and time-dependently enhanced the proliferation of splenocytes without cytotoxicity. Our results also showed that the number of $CD4^+$ helper T cells and CD45R/$B220^+$ pan B cells increased markedly, but not $CD8^+$ cytotoxic T cells or $CD11b^+$ granulocytes/macrophages. In addition, OPFE significantly decreased the production levels of T helper (Th) 1 type cytokines, interferon (IFN)-$\gamma$, and tumor necrosis factor (TNF)-$\alpha$, although had no significantly differences in those of interleukin (IL)-4, a Th2 type cytokine in concanavalin A (Con A)-stimulated blastogenic cells. Furthermore, OPFE alone strongly increased IL-4 production and decreased TNF-$\alpha$ production even in the absence of Con A. On the basis of these results, this study suggests that OPFE enhances immunity by regulating the pro- and anti-inflammatory response, indicating that this extract exerts a marked immunomodulatory effect, confirming its usefulness as therapy for immune-related diseases.

  • 1. Objectives Yanggyuksanhwa-tang for Soyangin was applied to investigate the immunological activities on antigen (Ag)-specific or Ag-non-specific immune responses on murine macrophage cell line (RAW 264.7) and ovalbumin/aluminium (OVA/Alum)-immunized mice. 2. Methods This study were carried out in nitric oxide (NO) synthesis on RAW 264.7 cells and cellular proliferation on mouse splenocytes. C57BL/6 mice were immunized intraperitonially with OVA/Alum (100 ${\mu}g$/200 ${\mu}g$) on day 1, 8, and 15. Yanggyuksanhwa-tang was administrated to mice orally for 3 weeks from day 1. On day 22, OVA-, lipopolysaccharide (LPS)-, and concanavalin A (Con A)-stimulated splenocyte proliferation and antibodies (OVA-specific antibodies of the IgG, IgG1, and total IgM classes) in plasma were measured. 3. Results Yanggyuksanhwa-tang significantly enhanced cellular proliferation by LPS and Con A on splenocytes from OVA/Alum-immunized mice (p<.001). Yanggyuksanhwa-tang also significantly enhanced plasma OVA-specific IgG (p<.001), IgG1 (p<.001), and total IgM (p<.01) levels compared with the OVA/Alum group. 4. Conclusions These results suggested that Yanggyuksanhwa-tang for Soyangin could be used as immunopotent.

  • This study was performed to evaluate the effect of Sorghum bicolor L. Moench(Sorghum, su-su) extracts on mouse immune cell activation. As ex vivo experiment, different concentrations(0, 50, 500mg/kg B.W.) of Sorghum bicolor L. Moench water extracts were orally administrated into mouse every other day for four weeks. The proliferation of mouse splenocytes, the number of plaque forming cells(PFC) and the cytokine IL-1β production by activated macrophage were used as indices for immunocompetence. Splenocyte proliferation was enhanced in mouse orally administrated with 50mg/kg B.W./day concentration compared to that of control group. Especially, the highest proliferation of spleoncyte was seen in the mouse orally administrated at the concentration of 50mg/kg B.W./day. The number of plaque forming cells(PFC) to SRBC were significantly enhanced when compared with control group. Also, the mouse of Sorghum bicolor L. Moench water extracts 50mg/kg B.W./day supplementation group with LPS stimulation enhanced level of IL-1$\beta$ cytokine production. This study suggest that supplementation of Sorghum bicolor L. Moench water extracts may enhance the immune function by regulating the splenocytes proliferation, increasing the number of PFC and enhancing the cytokine production by activated macrophage.

  • Lactic acid bacteria (LAB) in fermented foods have attracted considerable attention recently as treatment options for immune diseases, the incidence of which has been increasing worldwide. The ability of 500 strains of LAB, isolated from kimchi, to induce TNF-${\alpha}$ production in peritoneal macrophages was investigated. Lactobacillus plantarum HY7712 most strongly induced TNF-${\alpha}$ production as well as NF-${\kappa}B$ activation. However, HY7712 inhibited NF-${\kappa}B$ activation in LPS-stimulated peritoneal macrophages. When HY7712 was orally treated in cyclophosphamide (CP)-immunosuppressed mice for 5 or 15 days, it reversed the body and spleen weights, blood RBC and WBC levels, and splenocyte and bone marrow cells that were reduced by CP. Orally administered HY7712 increased concanavalin A-induced T cell proliferation to 84.5% of the normal group on day 15, although treatment with CP alone markedly reduced it to 53.7% of the normal group. Furthermore, orally administered HY7712 significantly induced the expressions of IL-2 and IFN-${\gamma}$ in ConA-induced splenic cytotoxic T cells of CP-treated mice. Orally administered HY7712 restored the CP-impaired phagocytosis of macrophages in mice. Orally administered HY7712 also restored the cytotoxicity of NK and cytotoxic T cells derived from spleen and bone marrow against YAC-1 in CP-immunosuppressed mice. Based on these findings, orally administered HY7712 may accelerate the recovery of cyclophosphamide-caused immunosuppression, without evident side effects, by immunopotentiating NK and Tc cells, and may provide a mechanistic basis for using HY7712 as an alternative means in lessening chemotherapyinduced immunosuppression in cancer patients.
