This study was conducted to assess the effect of highly concentrated onion intake on rodents. The experimental animals were divided two groups as follows; water administered group (CON) and Allium cepa administered group (ACE). The ACE group showed a slightly increases in the number of erythrocytes (RBC), hemoglobin (HGB), hematocrit (Hct) levels compared to the control group (p<0.05). Hemoglobin, monocyte, lymphocyte and neutrophil had no significant change (p>0.05) in ACE group and control group. The analysis of glutamic oxaloacetic transaminase (GOT) and glutamic pyruvic transaminase (GPT) levels showed a significant decrease in ACE group compared to the control group (p<0.05). The blood glucose, total protein, HDL-cholesterol were slightly high in ACE group, while triglyceride, total cholesterol levels were lower in ACE group compared to the control group (p<0.05). The levels of cytokines (interluekin-1α (IL-1α), interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), interleukin-10 (IL-10), interferon-γ (INF-γ), interleukin-18 (IL-18), interleukin-2 (IL-2), granulocyte-macrophage colony-stimulating factor (GM-CSF)) involved in immunity and inflammation in liver tissue and blood have all been confirmed to be within normal range. These findings could be used as basic data to show that highly concentrated dietary onion extract is not toxic to hematological indicators and immune functions.

목적 : 본 연구는 Interleukin 4 Receptor (IL-4R) 유전자 다형성이 중풍의 발병과 관련이 있는지 알아보기 위해 수행되었다. 대상: 대구한의대학교부속 한방병원에 입원한 중풍환자 56명과 종합건진센터에 내원한 중풍 기왕력이 없는 건강인 83명을 대상으로 하였다. 방법 : 각 그룹에서 개개인마다 DNA를 분리 정제한 후 Taq polymerase로 증폭하여 한천 겔에서 전기영동을 하여 PCR 산물을 확인하였다. PCR 산물은 Pyrosequencing 과정을 통하여 IL4R의 유전형이 자동으로 판정되었다. 결과 : A/A, A/G, G/G의 세가지 유전자형이 검출되었으며 중풍군과 대조군 사이에 유의성 있는 차이가 발견되었다(p=0.005). 그러나 개별 allele 빈도에 있어서는 중풍군과 건강인 사이에 통계적인 유의성이 나타나지 않았다(p=0.995). 결론 : 이상의 결과를 통하여 IL4R 유전자 다형성은 중풍의 발병과는 관련성이 있는 것으로 사려되지만 더 많은 환자를 대상으로 다른 환경요인 또는 유전자와의 연관성에 대한 심도있는 연구가 필요하다고 하겠다.

Sinensetin, a pentamethoxyflavone, is known to exert various pharmacological activities including anti-angiogenesis, anti-diabetic and anti-inflammatory activities. However, its effects on the human mast cell - 1 (HMC-1) mediated inflammatory mechanism remain unknown. To explore the mediator and cellular inflammatory response of sinensetin, we examined its influence on phorbol 12-myristate 13-acetate (PMA) plus A23187 induced inflammatory mediator production in a human mast cell line. In this study, interleukin (IL)-6 production was measured using the enzyme-linked immunosorbent assay and reverse transcription polymerase chain reaction. Sinensetin inhibited PMA plus A23187 induced IL-6 production in a dose-dependent manner as well as IL-4, IL-5 and IL-8 mRNA expression. Furthermore, sinensetin inhibited signal transducer and activator of transcription 3 (STAT3) phosphorylation, suggesting that sinensetin inhibits the production of inflammatory mediators by blocking STAT3 phosphorylation. Moreover, sinensetin was found to inhibit nuclear factor kappa B activation. These findings suggest that sinensetin may be involved in the regulation of mast cell-mediated inflammatory responses.

A fusion protein of human interleukin-2(hiL-2) and glucagon which was expressed in Escherichia coli. was digested with enterokinase for recovery of hIL-2 from the fused protein. To obtain hIL-2 of optimum recovery hydrolysis reaction were performed under various conditions of urea additives and reaction time. hIL-2 was finally purified by RP-HPLC(reversed phase-HPLC) to remove cleaved G3 fusion partner and residual uncleaved G3-IL-2 HIL-2 was eluted in a single peak at 100% acetonitrile at 28 min. Optimum urea concentration was found to be 0.5 M and 24 h reaction time was sufficient without any additive such as CaCl2 and Tween-20.

We have previously reported that Korean schizophrenic patients hove low production of IL-2 in vitro suggestive of autoimmunity to the pathogenesis of the disorder. In an attempt to further explore this issue, we measured in vivo serum levels of interleukins(IL-$1{\beta}$, IL-2, and IL-6) using a quantitative "sandwich" enzyme immunoassay(ELISA) in 26 male schizophrenic patients and in 26 age-matched normal controls. Patients met DSM-IV criteria for schizophrenia and were drug free for at least six months. The severity of symptoms was assessed by SANS and SAPS. We found a significant increase of IL-2 level(p<0.05) in schizophrenic patients as compared with normal controls. There were significant positive correlations between IL-2, IL-6 levels and negative symptom scores. There were no correlations between age, age at onset, duration of illness and interleukin levels. Our results may support the hypothesis of viral-autoimmune dysfunction in schizophrenia. IL-2 or IL-6 may be associated with specific clinical feature in schizophrenic syndrome, especially negative symptom.

Purpose: Podocytes are important architectures that maintain the crucial roles of glomerular filtration barrier functions. Despite this structural importance, however, the mechanisms of the changes in podocytes that can be an important pathogenesis of minimal change nephrotic syndrome (MCNS) are not clear yet. The aim of this study was to investigate whether apoptosis is induced by interleukin (IL)-13 in cultured human podocytes. Methods: Human podocytes were treated with different IL-13 doses and apoptotic cells were analyzed using terminal deoxynucleotidyl transferase dUTP nick-end labeling (TUNEL assay) and fluorescence-activated cell sorting (FACS). Results: The IL-13 increased the number of TUNEL-positive cells in a dose-dependent manner at 6 and 18 hours (P<0.05 and P<0.05, respectively). The apoptosis rate was appeared to be increased slightly in the IL-13-stimulated podocytes (8.63%, 13.02%, and 14.46%; 3, 10 and 30 ng/mL, respectively) than in the control cells (7.66%) at 12 hours by FACS assay. Conclusion: Our study revealed that IL-13 expression may increase podocyte apoptosis. Blocking the IL-13 signal pathway can potentially play an important role in regulating the apoptosis of podocytes.

Interleukin-9 (IL-9) is well known for its role in allergic inflammation. For cancer, both pro- and anti-tumor effects of IL-9 were controversially reported, but the impact of IL-9 on tumor metastasis has not yet been clarified. In this study, IL-9 was expressed as a secretory form (sIL-9) and a membrane-bound form (mbIL-9) on B16F10 melanoma cells. The mbIL-9 was engineered as a chimeric protein with the transmembrane and cytoplasmic region of TNF-α. The effect of either mbIL-9 or sIL-9 expressing cells were analyzed on the metastasis capability of the cancer cells. After three weeks of tumor implantation into C57BL/6 mice through the tail vein, the number of tumor modules in lungs injected with IL-9 expressing B16F10 was 5-fold less than that of control groups. The percentages of CD4⁺ T cells, CD8⁺ T cells, NK cells, and M1 macrophages considerably increased in the lungs of the mice injected with IL-9 expressing cells. Among them, the M1 macrophage subset was the most significantly enhanced. Furthermore, peritoneal macrophages, which were stimulated with either sIL-9 or mbIL-9 expressing transfectant, exerted higher anti-tumor cytotoxicity compared with that of the mock control. The IL-9-stimulated peritoneal macrophages were highly polarized to M1 phenotype. Stimulation of RAW264.7 macrophages with sIL-9 or mbIL-9 expressing cells also significantly increased the cytotoxicity of those macrophages against wild-type B16F10 cells. These results clearly demonstrate that IL-9 can induce an anti-metastasis effect by enhancing the polarization and proliferation of M1 macrophages.

To investigate the role of interleukin-l$\beta$ (IL-1$\beta$) in the embryonic development, in vivo and in vitro expression patterns of IL-1$\beta$ gene in the preimplantation mouse embryos were examined by RT-PCR, and the effects of explanted mouse ovi-duct and uterine epithelial cells on the expression of IL-1$\beta$ gene in the pleimplantation mouse embryos were examined by co-culture. IL-1$\beta$ mRNA was detected in the embryos from 4-cell stage to blastocyst stage in vivo and from morula stage to hatching blastocyst stage in vitro. This transcript was not detected from the GV stage to late 2-cell stage in vivo, and not at the 4-cell and 8-cell stages in vitro. For the co-culture of late 2-cell embryos with the explanted mouse oviduct and uterine epithelial cells, oviducts and uterine epithelial cells were isolated at 48 hour alter the hCG injection. The explanted oviduct and uterine epithelial cells in co-culture groups facilitated the IL-1$\beta$ gene expression of the mouse embryos in comparison with the control. Taken together these results suggest that the presence of IL-1$\beta$ plays an important role in preimplantation embryonic development. In addition, the up-regulation of IL-1$\beta$ gene expression by the explanted oviduct and uterine epithelial cells demonstrates that embryonic expression of IL-l$\beta$ gene may be regulated by the interaction with oviductal and uterine factor (s).
