  • Recombinant interleukin-2 (IL-2) has demonstrated as an antineoplastic agent in mice and human, but the relatively low response rates observed in clinical trials. Therefore, the present study was undertaken in order to evaluate therapeutic activities of IL-2 for the establishment of therapeutic applications. At the onset of the experiment, normal C3H/HeN mice were injected with $3{\times}10^6$ RD-995 tumor cells, murine ultraviolet radiation-induced fibrosarcoma, subcutaneously. Beginning on day 25, experimental groups were treated with a 5-day course of IL-2 (subcutaneous injection of 30,000 IU every 12 hours for 5 days). The result of this experiment revealed that RD-995 tumor grew progressively in control mice. Subcutaneous IL-2 therapy decreased tumor growth until day 23, then the tumor grew progressively. No significant difference in the survival of IL-2 therapy decreased tumor growth until day 23, then the tumor grew progressively. No significant difference in the survival of IL-2 therapy decreased tumor growth until day 23, then the tumor grew progressively. No significant difference in the survival of IL-2 treated mice were observed compared with the control mice.

  • In this report, we investigated the effect of aqueous extract of vinegar treated small black soybean (Glycine max Merr.) (Leguminosae) (VSBS) on mast cell-mediated allergic reaction and pro-inflammatory cytokine secretion. VSBS inhibited compound 48/80-induced systemic reactions. VSBS attenuated immunoglobulin (Ig) E-mediated passive cutaneous anaphylaxis. In addition, VSBS decreased the phorbol 12-myristate 13-acetate plus calcium ionophore A23187-stimulated secretion of tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-6 and interleukin (IL)-8 in human mast cells. Our findings provide evidence that VSBS inhibits mast cell-derived allergic reactions.

  • Asthma is a chronic disease and occurs in airway in the lung. The cause of the disease has not been identified, it is assumed that both genetic and environmental risk factors play an important role in the development of asthma. Interleukin (IL)-12 is a cytokine regulating T-cell and NK cell. In this study, we analyzed the genetic polymorphisms of IL-12 receptor genes (IL-12Rβ1 and IL-12Rβ2) in asthma patients and normal individuals in a Korean population. We analyzed single nucleotide polymorphisms (SNPs) in IL-12Rβ1 and IL-12Rβ2 using the genotype data of 193 asthma cases and 3,228 healthy controls from the Korea Association REsource for their correlation with asthma case. IL-12Rβ1 and IL-12Rβ2 genes showed statistically significant polymorphism association with asthma case. As a results, 16 SNPs from IL-12Rβ1 and IL-12Rβ2 genes showed statistically significant association with asthma. Among them, rs375947 SNP in IL-12Rβ1 showed the greatest statistical correlation with asthma (P-value = 0.028, Odds Ratio = 1.27, 95% Confidence Interval = 1.03~1.57). The groups with minor allele of IL-12Rβ1 and IL-12Rβ2 showed increased risk of asthma. The genotype-based mRNA expression analysis showed that the group of minor allele of IL-12Rβ1 showed decreased mRNA expression. Decreased IL-12Rβ1 expression causes decreased IL-12 signaling, and this affects developing asthma. In conclusion, the SNPs in IL-12Rβ1 and IL-12Rβ2 may contribute to development of asthma in a Korean population.

  • Objective : The purpose of this study was to investigate the anti-inflammatory effects of Hwagae-san extract(HGSE) on the peritoneal macrophage. Methods : To evaluate anti-inflammatory effects of HGSE, We measured cytokines(interleukin-6; IL-6, interleukin-12; IL-12, tumor necrosis factor-${\alpha}$; TNF-${\alpha}$) and nitric oxide(NO) production in lipopolysaccharide(LPS)-induced macrophages. Furthermore, We examined molecular mechanism using western blot and also LPS-induced endotoxin shock. Results : 1. HGSE did not have any cytotoxic effect in the peritoneal macrophages. 2. HGSE reduced LPS-induced IL-6, TNF-${\alpha}$, IL-12 and NO production in peritoneal macrophages. 3. HGSE inhibited the activation of extracelluar signal-regulated kinase(ERK), C-Jun NH2-terminal kinase(JNK) but not of p38, degradation of IkB-${\alpha}$ in the LPS-stimulated peritoneal macrophages. 4. HGSE inhibited the production of TNF-$\alpha$, IL-6 and IL-12 in serum after LPS injection. Conclusion : These results suggest that HGSE may inhibit the production of TNF-${\alpha}$, IL-6, and IL-12 through inhibition of ERK and JNK activation, and that HGSE may be beneficial for inflammatory diseases.

  • This experimental study was carried out to evaluate the effects of Acanthopanacis cortex on Cytokine-inducing and and immune response in Mice. In order to investigate the effect of Acanthopanacis cortex, the following was performed; Cytotoxicity, in vitro, the fraction of $CD4^+$, $CD8^+$, $B220^+$ in splenic cell, gene expression of IL-12(p35), IL-12(p40), IFN-${\gamma}$, and splenic cell proliferation by Acanthopanacis cortex. Analysis of cytokine gene expression was carried out by RT-PCR amplification. Amplified PCR products were electrophoresed on 1.2% agarose gel, and the analysis (Ht) was used to 1D-density program. The results were obtained as follows. Acanthpanacis cortex showed didn't have cell toxicity under $12{\mu}g/m{\ell}$ group on mouse lung fibroblast cells. In an in vitro model using mouse peripheral blood mononuclear cells (PBMCs), extract of Acanthpanacis cortex induced multiple cytokine, including interleukin-12 (p35), interleukin-12 (p40), interferon-gamma (IFN-${\gamma}$). The extract also enhanced the percentages of the $CD4^+$, and $CD8^+$ in the untreated control were $22.1{\pm}3.3$ to $38.4{\pm}2.1$, and $5.0{\pm}0.4$ to $10.7{\pm}0.3%$, respectively. From above findings, it is suggested that Acanthopanacis cortex is able to anti-cancer and activate immune response system.

  • Background : Cytokines are chemical mediators that control and modulate many inflammatory processes. They work in different fashions in a variety of diseases. Discriminating between malignant effusion, tuberculous effusion, and parapneumonic effusion are crucial from the clinical view-point in Korea. In the current study, interferon-gamma (IFN-${\gamma}$), soluble interleukin-2 receptor (IL-2R), interleukin-6 (IL-6) and interleukin-10 (IL-10) were measured for this purpose. Methods : Pleural fluids from patients with malignant disease, tuberculosis, parapneumonic effusion and lung empysema were collected and gauged using commercial ELISA kits. Results : 34 patients were enrolled in this study. Among these 15 cases were malignant effusions, 12 were tuberculosis pleurisy and 7 were parapneumonic effusion and lung empyema. The levels of cytokines measured in this study were as follows, in order of frequency, malignant effusion, tuberculous effusion, parapneumonic effusion and lung empyema. The levels of INF-${\gamma}$ were higher in tuberculous effusion than in malignant or parapneumonic effusion ($295.5{\pm}585.5$ vs. $16.7{\pm}50$ vs. $10.0{\pm}0$ pg/ml, p>0.05). The levels of IL-2R were higher in tuberculous effusion than in malignant or parapneumoruc effusion ($7423.5{\pm}3752.8$ vs. $3247.4{\pm}1713.3$ vs. $3790.2{\pm}3201.1$ pg/ml, p<0.05). No significant differences were found in the levels of IL-6 between the groups ($600{\pm}12.8$ pg/ml in malignant effusion, $556.4{\pm}161.7$ pg/ml in tuberculous effusion, $514.4{\pm}224.8$ pg/ml in parapneumoruc effusion). IL-10 levels were higher in parapneumoruc effusion than in malignant or tuberculous effusions ($98.4{\pm}141.7$ vs. $28.2{\pm}55.5$ vs. $11.3{\pm}11.7$ pg/ml, p<0.05). Conclusion : These results suggest that the measurement of IL-2R levels in pleural fluids may be a useful means of differentiating between tuberculous effusion and pleural effusions of other origins, and that the measurement of IL-10 levels in pleural fluids may be useful to differentiate between parapneumonic effusion and pleural effusions of other origins.

  • Atherosclerosis is a chronic inflammatory disease of the arterial wall characterized by progressive accumulation of lipids, cells, and extracellular matrix. Matrix metalloproteinases(MMPs) and tissue inhibitor of metalloproteinases(TIMPS) contribute to vascular matrix remodeling in atherosclerosis, and some cytokines may play role in the synthesis or activation of MMPs or TIMPs. Material and Method: We produced experimental atherosclerotic plaques in 9 rabbits by atherogenic hypercholesterol diet for 12 weeks, and 10 other rabbits were used as control group with standard laboratory chow, At that time, 19 rabbits were sacrificed and aorta, coronary arteries and blood specimens were prepared. The expressions of MMP-9, TIMP-2 and interleukin(IL)-18, and the bioactivity of IL-6 were investigated with H&E stain, immunohistochemical stain, immunoblotting(Western blot analysis), and bioassay. Result: Serum cholesterol in the experimental group increased up to 1258$\pm$262 mg/dL(control group: 41$\pm$7 mg/dL). All experimental group showed well-developed atherosclerotic plaques in aorta and coronary artery. The expression of MMP-9 in aorta and coronary artery of the experimental group showed significant increase than that of the control group by immunohistochemistry. Among the experimental group, complicated lesions with intimal rupture or complete luminal occlusion, demonstrated stronger expression of MMP-9. Interestingly, there was no difference in expression of TIMP-2 between the experimental and the control group. These findings were confirmed by Western blot analysis. The bioassay revealed significant up-regulation of serum bioactivity of IL-6 in the experimental group(4819.60$\pm$2021.25 IU/$m\ell$) compared to that of IL-6 in the control group(27.20 $\pm$ 12.19 IU/$m\ell$). IL-18 was expressed in all atherosclerotic plaques, whereas little or no expression was detected in the control group. Conclusion: The increased MMP-9 expression along with the unchanged TIMP-2 expression seem to be contributory factors in extracellular matrix degradation in atherosclerosis. Focal overexpression of MMP-9 may promote plaque destabilization and cause complications of atherosclerotic plaques such as thrombosis with/without acute coronary syndrome. Elevation of IL-6 and IL-18 may be more than just markers of atherosclerosis but actual participants in lesion development. Identification of critical regulatory pathway is important to improve the understanding of the cellular and molecular basis of atherosclerosis and may open the way for novel therapeutic strategies.

  • Objectives ; This study was to investigate the anti-cancer effects of herbal acupuncture with distilled fresh ginseng. The herbal acupuncture was injected to Chung-wan($C.V_{12}$) and Wisu($BL_{21}$) of mice that were subjected to Sarcoma-180 adbominal cancer cell and A549 human epithelial lung cancer cells in vitro. Methods : Anti-cancer effects of distilled fresh ginseng herbal acupuncture were tested by measruing Cox, Bcl-2, and Bax by using RT-PCR in A549 human epithelial lung cancer cells in vitro. And four weeks old Balb/c line male mice weighing around $20\;{\pm}\;3g$ were used to measure survival rate and anti-cancer effect to outputs of interleukin-2 and interleukin-4 using flow cytometry, possibility of mRNA menifestation using RT-PCR, and Cox mRNA. The results are as follows. Results : 1. In measuring mRNA menifestation in Cox, Bcl-2, and Bax by using RT-PCR in A549 human epithelial lung cancer cells in vitro, the result showed that fresh ginseng decreased Cox-2 which is directly involved in Inflammation process. 2. Survival rate was measured in an anti-cancer effect experiment against Sarcoma-180 abdorminal cancer. Median survival time of controlled group was 27 days, of experiment group I was 21 days, and of experiment group II was 27 days. Therefore, experiment group I showed -22.2% increase in survival rate and experiment group II showed no difference compare to controlled group. 3. There was no difference between condition group and controlled and experiment group in measuring outputs of interleukin-2 and interleukin 4 by using flow cytometry 4. In measuring outputs of interleukin-2 by using ELISA, there was no significant difference between condition group and controlled group and there was decrease in experiment group II compared to conditioned and controlled group. 5. In measuring cytokine mRNA menifestation by using RT-PCR, experiment group I showed increase of mRNA menifestation in interleukin-2,4 and $interferon-{\gamma}$ and experiment group II showed no significant difference in $interferon-{\gamma}$. Conclusion : According to the results, fresh ginseng herbal-acupuncture took a little effects in cancer. In using distilled fresh ginseng herbal acupuncture has effect on Cox-2 decrease. However, the difference in concentration of fresh ginseng showed no effect on killing cancer cell. It is assumed that inaccurate concentration of herbal acupuncture and fresh ginseng component could be the reason for this result. Therefore, future consideration will be studies on herbal acupuncture concentration.
