  • Scorpion (SCP) has been clinically used for the treatment of endogenous wind to relieve convulsion, clearing away toxins, resolving hard masses and removing obstruction in the collaterals to relieve pain. Recent studies showed that scorpion toxins that affect the activating mechanism of sodium channels and indian black scorpion venom induced anti-proliferative and apoptogenic activity against human leukemic cell lines U937 and K562. There is lack of studies regarding the effects of SCP on the immunological activities. The present study was conducted to evaluate the effect of SCP on the regulatory effects of cytokines and nitric oxide (NO) for the immunological activities in Raw 264.7 cells. After the treatment of SCP MeOH extract dissolved in media for 1 h prior to the addition of lipopolysaccharide (LPS: 1 ${\mu}$g/ml), cell viability was measured by MTT assay, NO production was monitored by measuring the nitrite content in culture medium. Inducible nitric oxide synthase (iNOS) was determined by immunoblot analysis, and levels of cytokine were analyzed by sandwich immunoassays. As results, SCP inhibited the production of nitrite and nitrate (0.3 and 1.0 mg/ml), iNOS and p-$I_KB_{\alpha}$ protein, tumor necrosis factor-${\alpha}$ (0.3 and 1.0 mg/ml), interleukin-1${\beta}$ (0.3 and 1.0 mg/ml) and interleukin-6 (1.0mg/ml) in Raw 264.7 cells activated with LPS. These findings suggest that SCP can produce anti-inflammatory effect, which may play a role in adjunctive therapy in Gram-negative bacterial infections.

  • This present study demonstrates the immunological synergistic effects of herbal preparation (HemoHIM) and red ginseng powder granule in various immune cell models (bone marrow-derived macrophages, dendritic cells, and mouse splenocytes) from mice. Both herbal preparation and red ginseng extracts were treated to bone-marrow derived macrophages, dendritic cells, and mouse splenocytes, and there was no cytotoxicity at a dose below $200{\mu}g/mL$. Cell proliferation and cytokine [tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-6, and IL-12] production tested in bone marrow-derived macrophages and dendritic cells significantly increased upon combined treatment. Cell surface marker (CD 80/86, MHC class I/II)-mediated immune cell activation was highly elevated by combined treatment. For cytokine production in splenocytes, combined treatment significantly increased production of Th 1 type cytokines [IL-2 and interferon (IFN)-${\gamma}$] but not Th 2 type cytokines (IL-4 and IL-10). Therefore, combined treatment with HemoHIM and red ginseng extracts is an effective method to establish powerful immunological synergy in immune cells.

  • The use of alkylating agent cyclophosphamide(CY), a widely used antitumor drug is well known as a potent immunosuppressant and has been used as a probe for investigating the functional capabilities of lymphocyte subsets of both T and B cells that play an important role in the regulation of the immune response. The present study was undertaken in an effort to assess the effects of CY on immunological memory in murine model. CY, given as a single dose of CY(250mg/kg) before sensitization with sheep red blood cells(SRBC) enhanced the primary response of Arthus and delayed-type hypersensitivity(DTH), as measured by footpad swelling reaction, but suppressed their tertiary DTH response. The similar CY pretreatment enhanced both the primary and tertiary hemagglutinin(HA) responses to SRBC, and the tertiary antibody response against polyvinylpyrroridone(PVP), a thymus-independent antigen but not the primary response against PVP. CY, given as a single dose of 250mg/kg 2 days before the primary immunization and two doses of 100mg/kg 2 days before the secondary and tertiary immunization, markedly suppressed the tertiary DTH and HA responses to SRBC. However, CY, given as small multiple daily doses(10mg/kg) over 4 days before sensitization but not after sensitization, enhanced the secondary HA response to SRBC. Contact sensitivity to dinitrofluorobenzene(DNFB) was suppressed by the drug, given either as a single large dose(300mg/kg) or as multiple dose(10mg/kg) administered 2 days before, together with or after DNFB sensitization. This suppression was more pronounced and more significant when CY was given as multiple dose. However, the enhancement of the secondary contact sensitivity to DNFB by CY was not clear-cut. The splenectomy appears to increase the enhancing effect of CY on contact sensitivity. These results suggest that CY selectively influences the immune response depending on the time of the drug administration relative to immunization and that the secondary or tertiary immune response involve memory cells with different susceptibilities to CY. Moreover, these results suggest that multiple low doses may sesectivley inhibit suppressor T cell proliferation involving DTH, HA or contact sensitivity without effecting helper T cells, but high doses presumably inhibit helper T cells and suppressor T cells with effecting B cells.

  • To clarify the activating effects of Buthus martensi Karsch on immunological function, its effect on primary and secondary antibodies production in mice of various ages was investigated. Buthus martensi Karsch increased the number of both antibody producing cells(anti-IgM and anti-IgG producing plaque forming cells, PFC) and phagocytic activity of peritoneal macrophage. Futhermore, these phenomena were significantly increased with aging in mice. Buthus martensi Karsch also increased natural killer cell activity concerning to cancer immunology. These results suggest that Buthus martensi Karsch markedly increases the reduced activity in the elderly and activates the immune response in senescence mice.

  • IL-9 has been reported to play dual roles in the pathogenesis of autoimmune disorders and cancers. The collaboration of IL-9 with microenvironmental factors including the broader cytokine milieu and other cellular components may provide important keys to explain its conflicting effects in chronic conditions. In this review, we summarize recent findings on the cellular sources of, and immunological responders to IL-9, in order to interpret the role of IL-9 in the regulation of immune responses. This knowledge will provide new perspectives to improve clinical benefits and limit adverse effects of IL-9 when treating pathologic conditions.

  • Objectives: This study aims to investigate the effects of voice disorders on changes in stress among people with damaged larynxes. To accomplish this, physiological changes and reductions in the stress of Sprague-Dawley rats whose larynx had been damaged were investigated after the laboratory animals were administered kudzu leaf extracts with sedative effects. Methods: In the experiment, a total of 24 rats were divided into four groups of six rats, including the normal group, control group, experimental group 1, and experimental group 2. After orally administering to the subjects a predetermined amount of the extract at a specific time (once per day over five weeks), changes in physiological functions, internal organ weight, cortisol, estrogen, and progesterone in the subjects were examined, and an immunological test was conducted on their brain tissues. Results: Statistical significance was seen in the experimental group as opposed to the control group and the results were similar to those of the normal group. Conclusions: In consideration of these results, it is deemed that there are severe effects on stress due to voice disorders and that the administration of kudzu leaf extracts results in improvement in stress.

  • In order to investigate the of effects of nalbuphine on immune system in mice, we examined the various immunological parameters. After single oral administration of nalbuphine (130, 260, 390 mg/kg, i.p.) to female ICR mite, the weights of bodies and organs (thymus, spleen, liver, kidney), and hematological parameters were examined on day 2, 4, 6, and 8. The increased rate of body weight, relative weight of organ, and hematological parameters in nalbuphine -treated groups, were not significantly changed when compared with control group. However, number of WBC was decreased by the treatment of nalbuphine. To assess the effects of nalbuphine on humoral immune responses, splenic IgM plaque forming cell (PFC) and serum IgM were assayed. When nalbuphine wat administered after immunization with SRBC, but not before immunization, splenic IgM PFC and ,serum IgM level against SRBC were significantly lowered in a dole -dependent manner. These results indicate that the suppressive effects of nalbuphine on primary humoral immune response may be dependent on the timing of its administration relative to the initial antigenic sensitization.

  • Objectives In the past, studies have been shown that Forsythiae Fructus (FF), Ulmi Cortex (UC) and JwaGwiEum (JGE) are effective in treating allergic reactions. However, no report shows the difference in effects of FF, UC and JGE in allergic rhinitis (AR). Therefore, the purpose of this study was to differentiate the effects of FF, UC and JGE in AR induced by ovalbumin (OVA) in mice. Methods From this experiment, the effects of FF, UC and JGE were several - changes in body weight, hematologic changes such as WBC, RBC, Hb and PLT counts, immunological changes such as levels of histamine, IgE, IL-4 and expressions of iNOS & COX-2 mRNA. Moreover, histological change of nasal mucosa was also investigated. Results FF administration group and JGE administration group significantly inhibited level of IgE compared to the control group. Also, FF administration group, UC administration group and JGE administration group inhibited IL-4 and expressions of iNOS & COX-2 mRNA. In histological assessment, FF administration group, UC administration group and JGE administration group showed reduced amount of subepithelial edema, desquamated mucosa and hyperplasia of basement membrane from OVA.

  • In order to investigate the effects of bisphenol A (BPA) on immune system in mice we examined the various immunological parameters. After single oral administration of BPA to female ICR mice, the weights of bodies and lymphoid organs, splenic cellularity and hematological parameters were examined on day 2 and 7. Among them WBC and splenic cellularity were slightly decreased on day 2. To assess the effects of BPA on humoral immune responses, splenic IgM plaque forming cell (PFC) and serum IgM were assayed. When BPA was administered after immunization with SRBC, but not before immunization, IgM PFC against SRBC was significantly lowered in a dose dependent manner. Serum IgM level was also decreased on day 4 when high dose (2000 mg/kg) of BPA was administrated after injection of OVA-antigen. The indexes of splenocyte proliferation (SP) to concanavalin A (Con A) and bacterial lipopolysaccharide (LPS) were measured in vitro by MTT assay. At low concentration BPA slightly increased splenocyte proliferation but at higher concentration it showed significant inhibitory effects on cell proliferation. Mitogen-stimulated SP was also determined with spleen cells from BPA treated mice. Con A-induced SP was slightly decreased and LPS-induced SP was especially inhibited at 1000 mg/kg and 2000 mg/kg of BPA. These results indicate that BPA is able to acutly evoke humoral and cell mediated immune suppression in mice.
