  • Purpose : Studies on the Regulatory Effect of Cytokine Production in Taumin Patients with Cerebral Infarction by Cheongsimyeonjatang Method : ELISA(enzyme-linked immuno-sorbent assay) Result : Chungsimyeunjatang(CYT) is a prescription for the cerebral infarction (CI) patients of Taeumin according to Sasang constitution philosophy. Taeumin patients with CI were treated with CYT during the acute stage. Clinical signs of CI disappeared markedly in about two to four weeks after oral administration of CYT in all patients. The mean interleukin (IL)-2 plasma levels were slightly lower in the patients with CI than in the normal groups, whereas the mean IL-4, IL-6 and IgE levels were significantly higher in the patients. There were no significant differences in $interferon-{\gamma}$ $(IFN-{\gamma})$ levels between the groups. Serum $IFN-{\gamma}$ and IL-2 levels derived from T helper (Th)1 cells were elevated significantly in the patients with CI by CYT administration. Significant reduced plasma levels of IL-4 and IL-6 derived from Th2 cells and IgE were observed in the patients treated with CYT. During the period of CYT administration, there were no other adverse effects. The data indicate that CYT has a good CI treatment effect, and that its action may be due to regulation of cytokine Production.

Result & Conclusion Yangkyuksanhwatang(YST) is a prescription for the cerebral infarction (CI) patients of Soyangin according to Sasang constitution philosophy. Soyangin patients with CI were treated with YST during the acute stage. Clinical signs of CI disappeared markedly in about 2 to 4 weeks after oral administration of YST in all patients. The mean interleukin (IL)-2 plasma levels were slightly lower in the patients with CI than in the normal groups, whereas the mean IL-4, IL-6 and IgE levels were significantly higher in the patients. There were no significant differences in interferon- ${\gamma}$ (IFN- ${\gamma}$ ) levels between the groups. Serum IFN- ${\gamma}$ and IL-2 levels derived from T helper (Th)1 cells were elevated significantly in the patients with CI by YST administration. Significant reduced plasma levels of IL-4 and IL-6 derived from Th2 cells and IgE were observed in the patients treated with YST. During the period of YST administration, there were no other adverse effects. The data indicate that YST has a good CI treatment effect, and that its action may be due to regulation of cytokine production.

  • This study was performed to investigate the in vitro effect of a corn water extract on immune function. Splenocyte proliferation was determined by the MTT(3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl terazolium bromide) assay after preparing asingle cell suspension. Production of macrophage-secreted interleukin(IL)-$1{\beta}$, IL-6, and interferon(IFN)-${\gamma}$, was detected by ELISA using a cytokine assay kit. After a 48-hr incubation with mitogens(ConA or lipopolysaccharide), mice splenocyte proliferation increased with the addition of a corn water extract supplement at 10, 50, 100, 250, 500, or $1,000\;{\mu}g/m\ell$. Production of IL-$1{\beta}$, IL-6, and IFN-${\gamma}$ increased in treatments supplemented with the corn water extract. In an in vitro study, splenocyte proliferation increased when $50\sim1,000\;{\mu}\ell/m\ell$ corn water extract was added. In an ex vivo experiment, the highest production of cytokines by activated peritoneal macrophages was observed in mice orally administered 500 mg/kg body weight/day.

  • To evaluate the role of nitric oxide (NO) in $IFN-{\gamma}$ production and apoptosis of splenocytes in genetically different strains of mice with toxoplasmosis, BALB/c (a toxoplasmosis resistant strain) and C57BL/6 (a toxoplasmosis susceptible strain) mice were infected with Toxoplasma gondii cysts orally and subsequently injected intraperitoneally with aminoguanidine, an iNOS inhibitor (AG; 35 mg/kg per mouse daily for 14 days). When BALB/c or C57BL/6 mice were infected with T. gondii without AG treatment, number of brain cysts, NO and IFN-y production by splenocytes, and percentages of apoptotic splenocytes were increased compared to uninfected control mice without AG treatment. AG treatment increased the number of brain cysts, and reduced NO and $IFN-{\gamma}$ production in T. gondii-infected C57BL/6 mice. In contrast, in T. gondii-infected BABL/c mice, the number of brain cysts, and NO and $IFN-{\gamma}$ production of splenocytes was not altered by treatment with AG. However, the percentages of apoptotic splenocytes in T. gondii-infected BALB/c or C57BL/6 mice were not affected by AG treatment. These results suggest that NO modulates $IFN-{\gamma}$ production in T. gondii-infected C57BL/6 mice, and that NO is involved in mediating a protective response in toxoplasmosis susceptible, but not resistant, mice strain during acute infection.

  • Purpose: The aim of this study was to evaluate whether infants with rhinovirus (RV) infection-induced wheezing and those with respiratory syncytial virus (RSV) infection-induced wheezing have different cytokine profiles in the acute stage. Methods: Of the infants with lower respiratory tract infection (LRTI) between September 2011 and May 2012, 88 were confirmed using reverse transcription polymerase chain reaction and hospitalized. Systemic interferon-gamma ($IFN-{\gamma}$), interleukin (IL)-2, IL-12, IL-4, IL-5, IL-13, and Treg-type cytokine (IL-10) responses were examined with multiplex assay using acute phase serum samples. Results: Of the 88 patients, 38 had an RV infection (RV group) and 50 had an RSV infection (RSV group). In the RV group, the $IFN-{\gamma}$ and IL-10 concentrations were higher in the patients with than in the patients without wheezing (P=0.022 and P=0.007, respectively). In the RSV group, the differences in $IFN-{\gamma}$ and IL-10 concentrations did not reach statistical significance between the patients with and the patients without wheezing (P=0.105 and P=0.965, respectively). The $IFN-{\gamma}$ and IL-10 concentrations were not significantly different between the RV group with wheezing and the RSV group with wheezing (P=0.155 and P=0.801, respectively), in contrast to the significant difference between the RV group without wheezing and the RSV group without wheezing (P=0.019 and P=0.035, respectively). Conclusion: In comparison with RSV-induced LRTI, RV-induced LRTI combined with wheezing showed similar $IFN-{\gamma}$ and IL-10 levels, which may have an important regulatory function.

  • The increase in alcohol consumption level has been noticed in Korea recently. Alcohol appreciably inhibits cell mediated immunity and this may contribute to the high prevalence of serious infection such as pulmonary tuberculosis among alcoholic subjects. The present study was undertaken to examine the effect of ethanol on the cyclooxygenase metabolites of human monocyte in vitro. Monocytes were activated with 800 units of gamma interferon(IFN-${\gamma}$) for 3 days following apply of Ficool-hypaque density gradient and gelatin coated flasks for separation of monocytes. Ethanol with addition of 100mM, 300mM and 600 mM for 30 minutes to 106 monocytes with/without previous IFN-${\gamma}$ treatment caused a dose dependent decrease in the production of thromboxane B2, 6-keto-PGE1$\alpha$ and PGE2 by radioimmunoassay at 6 hours after ethanol treatment. Quite different from the findings after 6 hours there was dose dependent increase in three prostaglandins without IFN-${\gamma}$ treatment after 24 hours of incubation. With previous treatment of IFN-${\gamma}$ reduced productions of three prostaglandins at 24 hours than control is spite of ethanol stimjulation. These findings show that IFN-${\gamma}$ can inhibit alcohol induced derangement of arachidonic acid metabolism of monocytes.

  • Background: Granulocyte-macrophage colony-stimulating factor (GM-CSF) gene-transduced tumor cell vaccines induce very potent systemic anti-tumor immunity in preclinical and clinical models. Our previous phase I clinical trial in patients with metastatic renal cell carcinoma (RCC) has demonstrated both immune cell infiltration at vaccine sites and T cell-mediated delayed-type hypersensitivity (DTH) response to whole tumor cell vaccines. Methods: To investigate the immune responses to autologous genetically- modified tumor cell vaccines, tumor-specific $CD8^+$ T cell lines were generated from peripheral blood lymphocytes (PBL) of a RCC patient 1.24 by repeated in vitro stimulation with either B7.1-transduced autologous RCC tumor cells or B7.1-transduced autologous tumor cells treated with interferon gamma ($IFN{\gamma}$), and cloned by limiting dilution. Results: Among several RCC-specific cytotoxic T lymphocytes (CTLs), a $CD4^+/CD8^+$ double positive T cell clone (17/A2) appeared to recognize $IFN{\gamma}$-treated autologous RCC restricted by HLA-B39. The 17/A2 also recognized other HLA-B39 positive RCC tumor cells after $IFN{\gamma}$ treatment. Conclusion: These results demonstrate that autologous RCC vaccination successfully generates the tumor-specific CTL 17/A2, and suggest that the presentation and recognition of the tumor antigen by the 17/A2 might be upregulated by $IFN{\gamma}$.

  • Objective : The present experiments were designed to study on the immune-enhancing effect of Mountain grown ginseng, Mountain cultivated ginseng, and Panax ginseng Method : In order to compare the immune-enhancing effect of moutain grown ginseng, moutain cultivated ginseng and Panax ginseng, the study was done through the forced swimming test (FST), measurement of T helper Th1, Th2 cytokines and fatigue related factors. Result : Moutain grown ginseng and panax ginseng decreased the immobility time in the FST compared to the control. Glucose, blood urea nitrogen (BUN), creatinine, lactate dehydrogenase (LDH) and Total-protein (T-protein) in serum were investigated. The serum achieved from ginseng administered mouse showed higher BUN, T-protein than the control. moutain grown ginseng administered group showed lower LDH than the control group. moutain grown ginseng administered mouse showed higher glucose than the control. Creatinine was same in either experimental or control group. Ginseng-induced cytokine production in human T-cell line, MOLT-4 cells and mouse peritoneal macrophages were compared. Moutain cultivated ginseng (10-4 dilution) and panax ginseng (10-3 dilution) were increased the interferon $IFN-{\gamma}$ production compared with media control (about 1.6-fold P<0.05) at 48 h. Moutain grown ginseng (10-4 dilution) was increased the $IFN-{\gamma}$ and interleukin IL-4 production compared with media control (about l.4-fold for $IFN-{\gamma}$ and 1.6-fold for IL-4 P<0.05) at 48 h. Moutain grown ginseng (10-3 dilution) and moutain cultivated ginseng (10-4 dilution) were increased the turmor necrosis factor $TNF-{\alpha}$ production compared with $rIFN-{\gamma}$ treated cells (about 1.9-fold for $TNF-{\alpha}$ P<0.05), respectively. Moutain cultivated ginseng (10-3 dilution) was increased the IL-12 production compared with $rIFN-{\gamma}$ treated cell (about 1.7-fold for IL-12 P<0.05). Conclusion : These data suggest that three different three kinds of ginseng act on immune responses in different aspects.

  • In this study, the preventive effects of Radix Trichosanthis extracts (RTE) against cytokine-induced ${\beta}-cell$ death were assessed. Cytokines generated by immune cells infiltrating pancreatic islets are crucial mediators of ${\beta}-cell$ destruction in insulin-dependent diabetes mellitus. The treatment of RIN cells with $interleukin-1{\beta}$ ($IL-1{\beta}$) and $interferon-{\gamma}$ ($IFN-{\gamma}$) resulted in a reduction of cell viability. RTE protected $IL-1{\beta}$ and $IFN-{\gamma}$-mediated viability reduction in a concentration-dependent manner. Incubation with RTE also induced a significant suppression of $IL-1{\beta}$ and $IFN-{\gamma}$-induced inducible nitric oxide synthase (iNOS) protein expression. The molecular mechanism by which RTE inhibited iNOS protein expression appeared to involve the inhibition of $NF{-\kappa}B$ activation. The $IL-1{\beta}$ and $IFN-{\gamma}$-stimulated RIN cells showed increases in $NF{-\kappa}B$ binding activityand $I{\kappa}B{\alpha}$ degradation in cytosol compared to unstimulated cells. However, pretreatment with RTE inhibited cytokines-induced $I{\kappa}B{\alpha}$ degradation and $NF{-\kappa}B$ activation in RINm5F cells. Furthermore, the protective effects of RTE were verified via protection of impairment in glucose-stimulated insulin secretions in $IL-1{\beta}$ and $IFN-{\gamma}$-treated islets.
