  • Objectives : The purpose of this study is to investigate the effect of Bacillus-fermented Scutellariae Radix acupuncture solution (SB) on interleukin(IL) production in mouse macrophage stimulatedby lipopolysaccaride(LPS). Methods : Productions of interleukins were measured y High-throughput Multiplex Bead based Assay with Bio-plex Suspension Array System based on $xMAP^{(R)}$(multi-analyte profiling beads) technology. To begin with, cell culture supernatant was obtained after treatment with LPS(1 ${\mu}g/mL$) and SB for 24 hour. Then, it was incubated with the antibody-conj${\mu}g$ated beads for 30 minutes. And detection antibody was added and incubated for 30 minutes. After incubating for 30 minutes, Strepavidin-conjugated Phycoerythrin(SAPE) was then added. Incubating for another 30 minutes, the level of SAPE fluorescence was analyzed on Bio-plex Suspension Array System. Results : The results of the experiment are as follows. SB significantly inhibited the LPS-induced production of IL-3($9.15{\pm}0.35$ pg/mL) by $6.92{\pm}0.05,\;7.21{\pm}0.11,\;6.96{\pm}0.33,\;and\;7.45{\pm}0.74$ pg/mL at the concentration of 25, 50, 100, and 200 ${\mu}g/mL$ in mouse macrophage RAW 264.7 cells (p<0.05). SB significantly inhibited the LPS-induced production of IL-5($7.30{\pm}0.48$ pg/mL) by $6.50{\pm}0.29,\;6.30{\pm}0.25,\;6.30{\pm}0.25,\;and\;5.80{\pm}0.25$ pg/mL at the concentration of 25, 50 100, and 200 ${\mg}g/mL$ in RAW 264.7 cells (p<0.05). SB significantly inhibited the LPS-induced productiion of IL-9($17.26{\pm}0.19$ pg/mL) by $15.01{\pm}0.43$ pg/mL at the concentration of 25 ${\mu}g/mL$ in RAW 264.7 cells(p<0.05). SB significantly inhibited the LPS-induced productioh of IL-13($187.80{\pm}2.90$ pg/mL) by $152.80{\pm}4.25,\;172.80{\pm}3.97,\;162.10{\pm}6.67,\;and\;165.30{\pm}11.80$ pg/mL at the concentration fo 25, 50, 100, and 200 ${\mu}g/mL$ in RAW 264.7 cells(p<0.05). SB significantly inhibited the LPS-induced production of IL-17($18.30{\pm}0.95$ pg/mL) by $13.30{\pm}1.25,\;13.80{\pm}1.11,\;13.30{\pm}0.75,\;and\;14.00{\pm}1.08$ pg/mL at the concentration of 25, 50 100, and 200 ${\mu}g/mL$ in RAW 264.7 cells(p<0.05). SB significantly inhibited the LPS-induced production of IL-23($43.90{\pm}0.83$ pg/mL by $39.50{\pm}1.26,\;38.00{\pm}1.78,\;and\;39.60{\pm}2.49$ pg/mL at the concentration of 25, 100, and 200 ${\mu}g/mL$ in RAW 264.7 cells(p<0.05). Conclusions : These results suggest that SB has anti-inflammatory activity related with its inhibition of IL-3, IL-5, IL-13, IL-17, and IL-23 production in macrophages.

  • Background: Cell mediated immune response mediated by interaction between CD4+ T lymphocytes and macrophagies is thought to play an important role in tuberculous pleurisy. This interaction is dependent on the interplay of various cytokines. The immunologic response of tuberculous pleurisy is thought to depend on the balance between helper T cell(Th1) cytokine Interleukin-12, Interferon gamma and Th2 cytokine IL-4, IL-10. To understand immunologic mechanism in tuberculous pleurisy and evaluate diagnostic value of these cytokines, the concentrations of Th1 cytokine IL-12, IFN -$\gamma$ and Th2 cytokine IL-10 were measured in tuberculous pleurisy and malignant pleural effusion group. Material and Methods: The concentrations of IL-10, IL-12 and IFN-$\gamma$ were measured by ELISA method in pleural fluids and serums of 20 patients with tuberculous pleurisy and 20 patients with malignant pleural effusion ADA activities were measured by spetrophotomery in pleural fluids of both groups. Results: In tuberculous pleurisy, the mean concentrations of IL-10, IL-12 and IFN-$\gamma$ of pleural fluids showed $121.3{\pm}83.7$ pg/mL, $571.4{\pm}472.7$ pg/mL and $420.4{\pm}285.9$ pg/mL. These were significantly higher than that of serum, $21.2{\pm}60.9$ pg/mL, 194.5 pg/mL, $30.1{\pm}18.3$ pg/mL respectively(p< 0.01). In malignant pleural effusion, the mean concentrations of IL-10, IL-12 and IFN-$\gamma$ of pleural fluids showed $88.4{\pm}40.4$ pg/mL, $306.5{\pm}271.1$ pg/mL and $30.5{\pm}54.8$ pg/mL respectively. Compared with that of serum ($43.4{\pm}67.2$ pg/mL, $206.8{\pm}160.6$ pg/mL, $14.6{\pm}3.3$ pg/mL), only IL-10 was significantly higher (p<0.001), but IL-12, IFN-$\gamma$ were not significant. In tuberculous pleural effusion compared with malignant pleural effusion, the concentration of IL-12, IFN-$\gamma$, ADA were significantly higher (p=value 0.046, <0.001, <0.001), but IL-10 was not significant. For differential diagnosis of tuberculous pleurisy from malignant pleural effusion, using cut-off value of IL-12, IFN-$\gamma$, ADA as 300 pg/mL. 100 pg/mL, 45 U/L, the sensitivity/specificity were 60%/70%, 90%/87.5%, 85%/90% respectively. Conclusion: In tuberculous pleurisy, IL-10, IL-12 and IFN-$\gamma$ were selectively concentrated highly in pleural space than serum. Compared with malignant pleural effusion, IL-12 and IFN-$\gamma$ were significantly higher, but IL-10 were not in tuberculous pleural effusion. The results suggest that Th1 pathway contributes to immune resistant mechanism in tuberculous pleurisy. IFN-$\gamma$ and ADA revealed useful methods of differential diagnosis in tuberculous pleurisy from malignant pleural effusion.

  • Objectives: We aimed to identify the dose-dependent inhibitory effects of Maekmundongcheongpye-eum and Liriopis Tuber on the mRNA expression of IL-6, IL-16, GM-CSF involved in the asthma model. Methods: In the study BEAS-2B cell lines, human epithelial cells were used. These cells were stimulated with tumor necrosis factor $(TNF)-{\alpha}$ for artificial inflammatory expression. ${\beta}-actin$ messenger RNA (mRNA) was used by internal standard. After 24 hours of Maekmundongcheongpye-eum, Liriopis Tuber-treatment, total cellular RNAs were collected, treating RNAzol directly on the alive cells. Then the transcriptional activities of IL-6, 16, GM-CSF were measured by RT-PCR with electrophoresis. Results: In the Maekmundongcheongpye-eum study, the mRNA expression of IL-6 showed 48% transcriptional inhibitory effect compared to the control group in the $100{\;}{\mu}l/ml$ category (P<0.001). In the IL-16, there was 53% and 57% transcriptional inhibitory effect compared to the control group in the $20{\;}{\mu}l/ml$ and $100{\;}{\mu}l/ml$ categories (P<0.001). In the GM-CSF, there was no inhibitory effect. In the Liriopis Tuber study, the mRNA expression of IL-6 showed 43% transcriptional inhibitory effect compared to the control group in the $100{\;}{\mu}l/ml$ category (p<0.005). In the IL-16, 34% and 26% of transcriptional inhibitory effect was shown compared to the control group in the $20{\;}{\mu}l/ml$ and $100{\;}{\mu}l/ml$ categories, respectively (P<0.05). In the GM-CSF, there was no inhibitory effect. Conclusions: This study shows that Maekmundongcheongpye-eum and Liriopis Tuber have dose-dependent inhibitory effects on the mRNA expression of IL-6 and IL-16 in BEAS-2B cell lines, human epithelial cells. Advanced studies are required to investigate the mechanisms of inhibition by herbal medicine in the asthma model.

  • Objective: In vitro culture of preimplantation embryos is improved by grouping embryos together in a drop of media. Individually cultured embryos are deprived of paracrine factors; with this in mind, we investigated whether the addition of a single embryo-secreted factor, interleukin-6 (IL-6), could improve the development of individually cultured embryos. Methods: Mouse embryos were cultured individually in $2{\mu}L$ of G1/G2 media in 5% oxygen and supplemented with a range of doses of recombinant mouse or human IL-6. Results: Mouse IL-6 increased hatching at doses of 0.01 and 10 ng/mL compared to the control (93% and 93% vs. 78%, p< 0.05) and increased the total number of cells at a dose of 0.1 ng/mL compared to the control ($101.95{\pm}3.36$ vs. $91.31{\pm}3.33$, p< 0.05). In contrast, the highest dose of 100 ng/mL reduced the total number of cells ($79.86{\pm}3.29$, p< 0.05). Supplementation with human IL-6 had a different effect, with no change in hatching or total cell numbers, but an increase in the percentage of inner cell mass per embryo at doses of 0.1, 1, and 100 ng/mL compared to the control ($22.9%{\pm}1.1%$, $23.3%{\pm}1.1%$, and $23.1%{\pm}1.1%$ vs. $19.5%{\pm}1.0%$, p< 0.05). Conclusion: These data show that IL-6 improved mouse embryo development when cultured individually in complex media; however, an excess of IL-6 may be detrimental. Additionally, these data indicate that there is some cross-species benefit of human IL-6 for mouse embryos, but possibly through a different mechanism than for mouse IL-6.

  • Background: Tumor necrosis factor(TNF)-$\alpha$ and Interleukin(lL)-$1{\beta}$ are thought to play a major role in the pathogenesis of the septic syndrome, which is frequently associated with adult respiratory distress syndrome(ARDS). In spite of many reports for the role of TNF-$\alpha$ in the pathogenesis of ARDS, including human studies, it has been reported that TNF-$\alpha$ is not sensitive and specific marker for impending ARDS. But there is a possibility that the results were affected by the diversity of pathogenetic mechanisms leading to the ARDS because of various underlying disorders of the study group in the previous reports. The purpose of the present study was to evaluate the roles of TNF-$\alpha$ and IL-$1{\beta}$ as a predictable marker for development of ARDS in the patients with septic syndrome, in which the pathogenesis is believed to be mainly cytokine-mediated. Methods: Thirty-six patients of the septic syndrome hospitalized in the intensive care units of the Asan Medical Center were studied. Sixteens suffered from ARDS, whereas the remaining 20 were at the risk of developing ARDS(acute hypoxemic respiratory failure, AHRF). In all patients venous blood samples were collected in heparin-coated tubes at the time of enrollment, at 24 and 72 h thereafter. TNF-$\alpha$ and IL-$1{\beta}$ was measured by an enzyme-linked immunosorbent assay (ELISA). All data are expressed as median with interquartile range. Results: 1) Plama TNF-$\alpha$ levels: Plasma TNF-$\beta$ levels were less than 10pg/mL, which is lowest detection value of the kit used in this study within the range of the $mean{\pm}2SD$, in all of the normal controls, 8 of 16 subjects of ARDS and in 8 in 20 subjects of AHRF. Plasma TNF-$\alpha$ levels from patients with ARDS were 10.26pg/mL(median; <10-16.99pg/mL, interquartile range) and not different from those of patients at AHRF(10.82, <10-20.38pg/mL). There was also no significant difference between pre-ARDS(<10, <10-15.32pg/mL) and ARDS(<10, <10-10.22pg/mL). TNF-$\alpha$ levels were significantly greater in the patients with shock than the patients without shock(12.53pg/mL vs. <10pg/mL) (p<0.01). There was no statistical significance between survivors(<10, <10-12.92pg/mL) and nonsurvivors(11.80, <10-20.8pg/mL) (P=0.28) in the plasma TNF-$\alpha$ levels. 2) Plasma IL-$1{\beta}$ levels: Plasma IL-$1{\beta}$ levels were less than 0.3ng/mL, which is the lowest detection value of the kit used in this study, in one of each patients group. There was no significant difference in IL-$1{\beta}$ levels of the ARDS(2.22, 1.37-8.01ng/mL) and of the AHRF(2.13, 0.83-5.29ng/mL). There was also no significant difference between pre-ARDS(2.53, <0.3-8.34ngfmL) and ARDS(5.35, 0.66-11.51ng/mL), and between patients with septic shock and patients without shock (2.51, 1.28-8.34 vs 1.46, 0.15-2.13ng/mL). Plasma IL-$1{\beta}$ levels were significantly different between survivors(1.37, 0.4-2.36ng/mL) and nonsurvivors(2.84, 1.46-8.34ng/mL). Conclusion: Plasma TNF-$\alpha$ and IL-$1{\beta}$ level are not a predictable marker for development of ARDS. But TNF-$\alpha$ is a marker for shock in septic syndrome. These result could not exclude a possibility of pathophysiologic roles of TNF-$\alpha$ and IL-$1{\beta}$ in acute lung injury because these cytokine could be locally produced and exert its effects within the lungs.

  • Objectives : We aimed to identify the dose-dependent inhibitory effects of Cheonsagunja-tang(喘四君子湯), leech(Hirudo medicinalis/水蛭) roasted with Ephedrae Herba(麻黃) on the mRNA expression of IL-6, IL-16, GM-CSF involved in the asthma model. Methods : In the study BEAS-2B cell lines, human epithelial cells were used. These cells were stimulated with tumor necrosis factor(TNF)-${\alpha}$ for artificial inflammatory expression. ${\beta}$-actin messenger RNA(mRNA) was used by internal standard. After 24 hours of the Cheonsagunja-tang, leech-treatment, total cellular RNAs were collected treating RNA zol directly on the living cells. Then the transcriptional activities of IL-6, 16 and GM-CSF were measured by RT-PCR with electrophoresis. Results: In the Cheonsagunja-tang study, the mRNA expression of IL-6 showed 30% transcriptional inhibitory effect compared to the control group in the $100{\mu}l/ml$ category(p<0.005). In the IL-16, there was 26%, 31% and 31% transcriptional inhibitory effect compared to the control groups in the $4{\mu}l/ml$, $20{\mu}l/ml$ and $100{\mu}l/ml$ categories, respectively(p<0.05). In the GM-CSF, the experimental group had 56% transcriptional inhibitory effect compared to the control group in the $100{\mu}l/ml$ category(p<0.001). In other concentrations, there was no inhibitory effect. In the leech study, the mRNA expression of IL-6 showed 37% transcriptional inhibitory effect compared to the control group in the $100{\mu}l/ml$ category(p<0.001). In the IL-16, there was 63% and 67% transcriptional inhibitory effect compared to the control groups in the $20{\mu}/ml$ and $100{\mu}/ml$ categories, respectively(p<0.001). In the GM-CSF, there was 64% and 68% transcriptional inhibitory effect compared to the control groups in the $20{\mu}l/ml$ and $100{\mu}l/ml$ categories, respectively(p<0.001). In other concentrations, there was no inhibitory effect. Conclusions : This study shows that Cheonsagunja-tang and leech roasted with Ephedrae Herba have dose-dependent inhibitory effects on the mRNA expression of IL-6, IL-16 and GM-CSF in BEAS-2B cell lines, human epithelial cells.

  • This study was carried out to investigate the anti-oxidative and anti-inflammatory effects of hot water extracts of Ligularia fischeri cultivated in Youngyanggun. We obtained hot water extract (HWE) and cold water extract (CWE) from L. fischeri. The anti-oxidative activities of L. fischeri extracts were measured by 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity. The anti-inflammatory effects of L. fischeri were evaluated in human mast cell line-1 (HMC-1) cells stimulated with phorbol-12-myristate-13-acetate plus A23187 (PMACI). The solid yields of HWE was 150% higher than CWE solid yield. Total polyphenol contents of HWE were $198.07{\pm}0.24mg/g$. The value of anti-oxidative activities of HWE were shown $IC_{50}$ $28.2{\pm}0.04ug/mL$. We showed that HWE significantly reduced the PMACI-induced the production of IL-6 (0.01-1 mg/mL), IL-8 (0.1-1 mg/mL), and $TNF-{\alpha}$ (0.01-1 mg/mL). These results indicate that the HWE of L. fischeri can be used as a functional material due to its antioxidant and anti-inflammatory activities.

  • This study was conducted to quantify chlorogenic acid content and evaluate biological activity, such as antioxidant, antibacterial, anti-inflammatory, and digestive enzyme activity of Aralia elata ethanol extract (AEE). The SC50 of DPPH and ABTS radical scavenging activities of AEE were 4.79±0.05 mg/mL, 5.79±0.05 mg/mL; total polyphenol and total flavonoid contents were 170.0±1.8 mgGAE/g, 105.5±4.1 mgQE/g, respectively. Nitric oxide (NO) was increased in RAW 264.7 cells and Caco-2 cells with treatment of LPS, and production of NO was inhibited by AEE in a concentration-dependent manner. Production of NO was reduced by 60.0±1.1% in RAW 264.7 cells and 50.7±2.8% in Caco-2 cells at of AEE. Similarly, the production of inflammatory cytokines (TNF-α, IL-1β and IL-6) was inhibited in a concentration dependent manner. Antibacterial activity increased as the dose concentration of AEE increased, and the MIC was 75 mg/mL for L. monocytogenes, and 100 mg/mL for S. typhimurium and H. pylori. In addition, amylase and protease enzyme activity was observed in AEE and increased enzyme activity was observed according to the concentration of the extract. AEE contained 7.06±0.01 mg/g of chlorogenic acid. As a result of the experiment, it is judged that it can be used as basic data for the development of health food using Aralia elata.

  • The purpose of this study is to investigate effects of White Ginseng-Ejung-tang water extract (EJ) on production of various cytokines such as interleukin (IL)-2, IL-5, IL-6, IL-10, IL-12p70, macrophage inflammatory protein (MIP)-2, vascular endothelial growth factor (VEGF), keratinocyte-derived chemokine(KC), tumor necrosis factor (TNF)-${\alpha}$, and granulocyte macrophage colony-stimulating factor (GM-CSF) in RAW 264.7 mouse macrophages stimulated by lipopolysaccharide (LPS). Levels of cytokines were measured by High-throughput multiplex bead array cytokine assay based on xMAP (multi-analyte profiling beads) technology. EJ significantly decreased levels of IL-2, IL-12p70, IL-5, MIP-2 for 24 h incubation at the concentrations of 25, 50, and 100 ${\mu}g/mL$ in LPS-induced RAW 264.7 (P < 0.05). EJ significantly decreased levels of IL-6 at the concentrations of 50 and 100 ${\mu}g/mL$ (P < 0.05). EJ significantly decreased levels of IL-10 and VEGF at the concentrations of 25 and 100 ${\mu}g/mL$ (P < 0.05). EJ significantly decreased levels of KC at the concentrations of 100 ${\mu}g/mL$ (P < 0.05). EJ did not show any significant effect on TNF-${\alpha}$ and GM-CSF production. These results suggest that EJ has anti-inflammtory property related with its inhibition of IL-2, IL-5, IL-6, IL-10, IL-12p70, MIP-2, VEGF, and KC production in LPS-induced macrophages.

  • Purpose : Abnormal activation patterns of Th1/Th2-cells have been suggested to increase the prevalence of allergic diseases. Prevention is regarded as an important corner stone in the management of allergic diseases. In this study, we have investigated the relationship between cord blood levels of IL-4, IL-10, and IL-12 in preterm newborns and the development of allergic respiratory diseases in infancy Methods : Forty-six preterm newborns born at the Ewha Womans University Mokdong Hospital between January 2003 and July 2005, were enrolled for this study, and consent was obtained to test their cord blood samples. Clinical history was obtained from the hospital records. Cord blood was obtained at birth and kept frozen until it was tested. The levels of IL-4, IL-10, and IL-12 were determined by enzyme-linked immunosorbent assay (ELISA). Results : All infants were followed-up for a median of $16.0months{\pm}13.2d$ (range, 12.0 to 36.0 months). Eighteen infants who developed wheezing showed lower cord blood levels of IL-12 ($366.60{\pm}140.40$ vs $435.09{\pm}91.20pg/mL$, P=0.009). Cord blood levels of IL-4 and IL-10 showed no significant difference between the two groups. Four newborns who later developed asthma, and infants with asthma showed lower IL-12 level in the cord blood than other groups. Conclusion : Lower concentration of cord blood levels of IL-12 in newborns who later developed wheezing and asthma suggested that they had abnormal activation patterns of Th1/Th2-cells at the time of birth, and cord blood IL-12 level can be used as a predictor of allergic respiratory diseases.
